Table 1. Recommendations which received Consent at the June 3-7, 2002 SG9 meeting.

Supplement 4 to the J-series of Recommendations, Terminology for new services in television andsound-program transmission, is a companion to Recommendation J.1. It was first generated tosupport the continuous updating of Recommendation J.1 needed to keep it current, which wasbecoming onerous since each update required formal approval.

The Rapporteur on terminology has recently developed a new approach to ease access to theterminology of SG9, in cooperation with F. Cantero, the ITU Counselor responsible for the ITU-Tterminology database available on the ITU web site under the acronym of SANCHO. The newapproach links the SG9 home page on the ITU web site, to the SG9 subset of the terminologydatabase contained in SANCHO. That link has now been made available on the SG9 web page.Using it, persons interested in the terminology used by SG9 can readily access it from the SG9home web page.



It was noted that the terminology database contained in SANCHO is updated as soon as a newRecommendation is approved, using its final text. Updates are thus much more systematic, timelyand accurate than the ones that the Rapporteur on terminology could introduce in RecommendationJ.1 or in Supplement 4.

Proposed Web Guide to ITU-T Recommendations

D.41, Proposal for a Web Guide to Recommendations of the ITU-T (Editor on Supplement 5 to theJ-Series of Recommendations), notes that Supplement 5 to the J-series of Recommendationsprovides a guide to the Recommendations in the J-series, relevant to various subjects in the scope ofStudy Group 9. It should be regularly updated to reflect new Recommendations in the J-series, asthey are approved.

The Administration of Italy recently submitted a proposal to TSAG. The proposal, if adopted andimplemented, would make Supplement 5 redundant. The proposal recommends a new database,freely accessible and prominently offered on the ITU web site, of information about eachRecommendation in the ITU. It would include:

• The number and title of the Recommendation,• A short summary of the Recommendation (e.g.: four lines of text),• A number of keywords, chosen from a standardized dictionary, by which the database can be

searched.

Each Study Group would be responsible to provide appropriate summaries of all the existing andnew Recommendations in its purview, and to also provide the relevant keywords for each one ofthem, while the ITU (TSB) would be responsible for the database administration. TSAG isexpected to consider this proposal at its forthcoming meeting.

In respect to the Italian proposal, the Editor for Supplement 5 notes the following.

• The number and title of all the Recommendations are already available in ITU databases.• The summaries of all recent Recommendations are also available, since it is required that a

summary be provided for each Recommendation submitted for approval. It should be easy tolink those summaries to the relevant Recommendations in the database.

• The keywords could be extracted from the text of each Recommendation, on the advice of therelevant Rapporteur.

The Editor for Supplement 5 consequently believes that it would be relatively easy to implement theItalian proposal. He also feels that a comprehensive guide to Recommendations provided on theITU web site would have a much higher profile, and it would be much more effective since it wouldeventually cover all the Recommendations of the ITU. The Editor for Supplement 5 consequentlyproposes that Study Group 9 should endorse the Italian proposal, that it should so inform theTSAG, and that work on Supplement 5 be suspended until the TSAG decides on the Italianproposal.

Plenary Highlights

D.42, Review of currency of N-Series Recommendations (P. Zaccarian, Rapporteur on VintageRecommendations), notes that Recommendations in the N-series have never been revisited after1988 or 1993. It thus seems legitimate to question their importance and currency today. N-seriesRecommendations address maintenance of international sound-program and television analogtransmission circuits. P. Zaccarian questions whether SG9 is willing to undertake this task.



D.45 (Liaison Rapporteur to ITU-R SG6) is a brief report on the March 2002 meeting of ITU-RSG6 (broadcasting services). Of interest to SG9 scope is the work performed on multimediastudies, which are jointly conducted in JRG-1 of SG6 and SG9. That work has led to the followingmain results. Three documents, together with the table in the Report on Common CoreSpecifications for the Applications Environment were sent ATSC, ARIB, DVB and OCAP seekingtheir comments in time for the next meeting of the JRG-1 in June of this year. The threedocuments are:

• Progress Report on the Harmonization of Procedural Functionalities for Interactive TV• Preliminary Considerations on the Harmonization of Declarative Functionalities for Interactive

TV• Interfaces between the Application and the System

Furthermore, WP 6M has further updated the Diagrammatic Representation of Interrelations ofRecommendations for Interactive Services. This is now becoming a very useful document.Unfortunately, no further progress on Digital Rights Management has been possible and WP 6Mmembers have been asked to solicit contributions from their professional contacts in time for thenext meeting of WP 6M in September 2002.

Information from this liaison related to D-Cinema is covered in the WG9 report, below.

TD-004 includes patent statement and licensing declarations on Recommendations J.mbi and J.ret.The statements are all from KDDI, Japan.

TD-043 (TSB) is a request for establishing a communication process with the Digital VideoBroadcasting (DVB). It notes to the DVB that SG9 is working on topics of interest to the DVB(multimedia home platform specifications and APIs), and that SG9 would like a closer relationshipbetween the ITU and DVB. The letter invites DVB to read Recommendations A.4 and A.5(attached), which define the formal communications between the ITU and other groups.

TD-031 is a report of the Informal Forum Summit meeting held December 3-4, 2001. On theinvitation of the Director of ITU TSB, representatives of a number of forums, ITU-T, and standardsdevelopment organizations (SDOs) met to improve awareness about each others’ organizations andrespective activities, to identify possible common ground/basis for improved cooperation with ITU-T, and to fulfill better their respective objectives in an increasingly complex telecommunicationsworld. One item came out clearly from the discussion: communication and better understanding ofactual work activities of each group is a critical factor. The representatives of the organizationsdeveloped a detailed list of best practices for communication between forums, ITU-T, and SDOsand also outlined possible types of further activity.

TD-046, Report on the Workshop on IPCablecom/Mediacom 2004/Interactivity in Multimedia(Geneva, March 12-15, 2002) (TSB), informs TSAG about the Workshop on MultimediaConvergence. The Workshop was set jointly by ITU-T and ITU-R.

Six sessions took place: Service and network architecture, Security and privacy, Multimedia QoS,Broadband delivery and in-home distribution, Interactivity in broadcasting, and Voice, video codingand speech processing. Coordination and harmonization issues dominated the agenda of thesesessions. However the session on Interactivity in broadcasting focused on Broadcast-basedMultimedia (BMM) which is already very popular and commercially available service in Europe,Japan and North America as part of regular broadcasting operations. In Europe all the BMMservices are invariably based on Digital Video Broadcasting (DVB) technology.



BMM services in Europe are planned to be further enhanced by embracing two novel multimediatechnologies, namely MHP and MPEG-4. Personal Versatile Recorders (PVRs) installed in TVset-top boxes will further enhance non-linear broadcasting (e.g., file transfer and streaming).

BMM uses digital satellite, terrestrial and cable delivery mechanisms. Return/Interaction channelscan be implemented either by specific broadcast channels (example: RCT) or by bi-directionaltelecommunication channels (such as 2.5G or 3G channels). The BMM QoS does not depend onthe number of simultaneous users and is thus not subject to regional or diurnal variations. In time-varying propagation channels (when receive terminal moves at a certain speed), the required bit rateof BMM does not depend on the speed. Consequently, the service quality does not diminish withthe terminal speed. Broadcast channels are capable of providing a guaranteed bandwidth of thetransmission channel and thus stable QoS.

Telecom-based Multimedia (TMM), both wired and wireless, is also under development, and thereare many trials currently in place to test the technology and business viability. The main issuesassociated with TMM that are currently under the discussion within ITU-T and the relevantindustry forums are the following: Service and Network architectures, Security and Privacy, Qualityof Service (QoS), and Voice and Video Coding.

The Workshop showed that the existing and future digital broadcast channels represent a suitablemeans for delivering multimedia, i.e., BMM. One example of a successful synergy between TVshows and SMS was given. Dedicated Internet websites have been set to leverage this synergy.

Broadcast networks are capable of providing ubiquitous coverage using a variety of differentcoverage scenarios, e.g., supranational, national, regional and local coverages. This capability ofuniversal coverage will allow the deployment of well-defined, stable and potentially large market andfast deployment of commercially viable BMM services.

TD-047 is a list of ITU-T SG9 incoming Liaisons Statements for this meeting. TD-118 is a list ofthe outgoing Liaison Statements from this meeting.

Working Group 1, IPCablecom

The Co-chairs of WG1 are E. Miller (Terayon) and N. Olsen (ADC). WG1 includes Questions 10(Functional characteristics for the interconnection of cable networks with the public switchednetwork and other delivery systems) and 13 (Voice and video IP applications over cable televisionnetworks). TD-092 is the report of this meeting

D.43 and TD-041 were presented for information; no specific action is required at this time. D.43,IPCablecom Recommendation J.160: further evolution (United Kingdom), provides a copy of ETSITR 101 963 v1.1.1, from ETSI TC AT. TD-041, IPCablecom Approval Summary For SCTE, ETSIAnd ITU-T SG9 (Associate Rapporteurs for Questions 10, 12 & 13/9), includes a large, usefultable that matches each IPCablecom topic to its input reference, SCTE latest standard, ETSI lateststandard and ITU-T latest recommendations.

TD-007, TD-008, and TD-016 are informational liaisons from SG13 and SG11 regarding the GIIand NGN projects, which were sent to all ITU-T study groups. TD-016 mentions the IPCablecomproject in the context of SG11’s future plans for cooperation in the context of the NGN project.No action is required.

TD-010, Comments on ITU-T Study Group 11 liaison on “Proposed joint activity on genericcontrol mechanism for end-to-end QoS service control and signaling protocol development basedon IP transfer capabilities and IP QoS classes” (ITU-T Study Group 13, January 22 – February 1,



2002), provides a significant amount of detailed information regarding SG13’s architecturaldirections for a generic QoS mechanism. It was noted that the extent of “coordination” with theIETF on IP QoS classes is minimal as the IETF does not produce any document that specifieslevels of performance. The base set of parameters used in defining the IP QoS classes in Y.1541(Network Performance Objectives for IP-Based Services) are consistent with the work of the IPPMworking group.

Study Group 13 envisions a solution that goes beyond voice to address the full range of multimediaand data applications. Thus emphasis is placed on indicating the specific application in addition toa requested Application QoS class and Traffic Descriptor.

The working group reviewed this information in the context of IPCablecom. Since the liaison wassent to many study groups and TD-064 and TD-065 already contain liaisons to SG13 regarding theIPCablecom QoS architecture, an additional liaison statement was not felt to be necessary.

TD-025, Liaison Statement on Consent of Draft New Recommendation M.2301 (Ex-M.23IP),Performance objectives and procedures for provisioning and maintenance of IP-based networks, isan informational liaison from Working Party 1/4 regarding the release of a new draftRecommendation. No response was deemed necessary.

TD-035, Response to Comments on G.799.1 (ITU-T SG15, April 29 – May 10, 2002), providesinformation regarding SG15’s selection of H.248 for their TIGIN gateway project, but does notrequest any action or response by SG9.

TD-054 (Study Group 12) alerts Study groups 2, 4, 9, 13, 15, 16, and ETSI project TIPHON of acall for the assessment of voice transmission quality from protocol analysis information on IPnetworks. The deadline for notification of the intent to respond is Aug. 31. Since there is no activework in SG9 in this area, it was felt that no response is needed.

J.175 (J.as), Audio Server Protocol, for “Consent”

J.175 (J.as_June_02.doc) is draft Recommendation J.as, Audio Server Protocol, proposed forConsent from the Dec. 2001 ITU-T SG9 meeting.

TD-110, Draft Liaison to SG16: SG9 response on J.171 (J.tgcp) and J.as (TD-027 and TD-071),is an outgoing liaison statement from the Dec. 2001 ITU-T SG9 meeting that was sent to SG16.There was considerable discussion surrounding the use of protocols other than the MGCP-basedprotocol specified in J.175 for the control of audio servers. D.23 from the Dec. 2001 SG9 meetingwas considered in this context. D.23 (UK; S. Alexander, BT) proposed that an alternative profilebased on H.248 be added to draft Rec. J.as.

TD-012 is the return Liaison to SG9 from Q3/16 on H.248 Profiles for J.tgcp and J.as. It providesthe following information relevant to J.as:

SG16 supports the use of H.248 for controlling audio servers. SG16 can not assume that H.248provides more or less functionality for controlling audio servers than an MGCP-based protocol,neither that cable operators prefer an MGCP-based solution.

SG16 considers that an H.248-based solution for audio servers would be consistent with theoffered use of an H.248-based solution for controlling media gateways. Furthermore, SG16 doesnot believe in the viability of the solution consisting in a device gateway located between the MPController and the MP to convert between MGCP and H.248. SG16 is not aware of any workhaving begun on such devices. Additionally, they would probably be complex devices (i.e.,



containing a state model) because of the large differences between H.248 and MGCP connectionmodels and commands. The complexity of such devices would probably prevent operators fromusing them, and then to finally use an H.248-based solution.

To be fully credible, an H.248-based solution has to be proposed for both gateways and audioservers. Symmetrical work has to be done for both MGCP- and H.248-based solutions forcontrolling Media Players. SG16 thinks D.23 is a good base for such a work, and would bepleased to provide any help to SG9 if needed.

TD-061 contains editorial clarification to the scope of J.175 (J.as_June_02.doc) regardinginterworking in order to address the concerns that were raised. Working Group 1 agreed that draftrecommendation J.175 (J.as_June_02.doc) as modified by TD-061 would be ready for submissionto the SG9 consent process. Rec. J.175 was Consented at the SG9 Plenary.

J.176 (J.memmib), MIB for Management Event Mechanism, for “Consent”

COM 9-40 is the proposed draft Recommendation on IPCablecom MIB for Management EventMechanism (J.memmib). The working group agreed that draft recommendation J.memmib wasready for submission to the Consent process. It was Consented as J.176 at the SG9 Plenary.

Supplement to J.160 concerning Emergency Telecommunications (ET)

D.53, Requirements for an Emergency Telecommunications Service (ETS) related to IPCablecomNetworks (United States of America), proposes that Study Group 9 consider, in their future work,the stated requirements of the Emergency Telecommunications Service (ETS). The goal is toensure that an Emergency Telecommunications Service will be able to function in the architecture,signaling, security, and other provisions of the IPCablecom family of Recommendations.Interworking of the ETS across different networks is a key requirement for ETS functionality overIPCablecom networks. However, it is understood that some requirements are not feasible in thenear term and therefore some of the requirements are considered as more important than others.

Emergency Telecommunications is an important topic being discussed by many study groupswithin the ITU. Of particular and urgent importance is the activity of requirements definition sothat relevant protocol work can be undertaken, where appropriate. Working Group 1 discussed themany incoming liaisons and other contribution regarding Emergency Telecommunications andagreed that the most appropriate action for SG9 is to cooperate with the overall requirementsdefinition process for the ITU-T, rather than to attempt to lead the process or to develop their ownset of requirements independent of the overall process. Rather, WG1 hopes to assist the overallEmergency Telecommunications requirements definition process in a contributor/reviewer capacity.WG1’s primary Emergency Telecommunications activity, then, will be to analyze the impact ofEmergency Telecommunication requirements, as they become known, on the IPCablecomarchitecture, and to take steps, when appropriate, to develop or modify the IPCablecom protocolmechanisms in support of those requirements.

As a tool to assist SG9 in this activity, WG1 created a draft supplement to J.160 (TD-066) for thepurpose of tracking Emergency Telecommunications requirements and assessing their impact onthe IPCablecom architecture. TD-084 is an outgoing liaison statement as a general response to allof the incoming liaison statements for this topic. TD-066 is attached to TD-084 for the informationof other ITU-T study groups and responds to incoming liaisons contained in TDs 014, 015, 018,026, 027, and 038:

TD-038, Proposed Revisions to E.106, Description of an international emergency preferencescheme (IEPS) (ITU-T SG2, May 7-16, 2002)

Proposed Amendment to J.165, Internet Signaling Transport Protocol (ISTP)

D.56, Proposed revision of Recommendation J.165: generic version - IPCablecom InternetSignaling Transport Protocol (ISTP) (United Kingdom), provides a draft of a revised IPCablecomRecommendation J.165 in a generic format, for study as a possible amendment for J.165. It startedas the study of a European Appendix for J.165 which became neither European nor NorthAmerican, but a generic ITU protocol that is basically the same everywhere.

In reviewing the document, the working group did not discover any technical issues, but the changein moving the appendix of that document to the main body requires more time for review bymembers than was available in the meeting. Thus the document was not put forward for consent.TD-069 was created as a liaison to SG11 informing them of the status of the work in SG9 on theproposed amendment to J.165, and the plan for progressing the document in the future.

Proposed Amendment to J.171, Trunking gateway control protocol (TGCP),Annex B

D.44, Annex B of Recommendation J.171 – Trunking gateway control protocol (United Kingdom),notes that currently Annex B of Recommendation J.171 is marked as “for further study based onH.248.” This document offers material for consideration as the contents of the new Annex B. It isbased on D.22 from the December 2001 SG9 meeting. This revision has the same technicalcontent but is in accordance with subsequent approval by ETSI Technical Committee AT.

TD-068 was created as a liaison to SG16 suggesting that a more complete analysis of the issuesinvolved in supporting both an IETF/H.248-based architecture and an IPCablecom J.171-basedarchitecture might preferably be performed by the ETSI group which originated the contribution. Itwas also noted that the SG16 need for “symmetry” in protocol could be accomplished by SG16referencing SG9 protocols. No changes are proposed by WG1 to J.171 at this time.

WG1 Liaisons

TD-011, Response to liaison statement on Generic QoS service requirements (Study Group 13),notes that SG13 welcomes the opportunity to collaborate on generic QoS issues that require broadconsideration beyond the development of BICC. User-to-user QoS control with multiple networktechnologies requires considerable coordination. The document attached to this liaison is work-in-progress, and gives SG13’s current view of the QoS signaling information exchange between usersand networks, and between networks. In particular, the work on parameter commitments is stillunder discussion. Work on this topic is in progress, and other alternatives will be considered.



TD-009 is a liaison statement on general QoS reference architecture for packet switched networksfrom Study Group 13. It notes that Q16/13 has agreed to adopt a new work item to develop ageneral QoS reference architecture for packet switched networks at the January meeting of SG13 inGeneva. The reference architecture is to serve as the general reference for any specific QoSapproach, current or emerging, within a packet switched network. It includes generic QoS buildingblocks (or functional components or network capabilities) that can be used in combination tocontrol the network response to a service request in various ways such that, for example, a serviceelement is provided with a level of response equal to or above a guaranteed minimum or is providedwith a superior level of network resource in case of resource contention. The building blocksidentified should not be constrained by a particular existing QoS approach such as DiffServ, MPLSor IntServ. Admission control, congestion feedback, metering and measurement, policy andpolicing, queuing and scheduling, resource reservation, service level agreement, tariff presentationand traffic marking are examples of possible generic QoS building blocks. An integral part of thenew work is the investigation of the impacts of security requirements and mechanisms on QoS.

TD-064 is a proposed response to TD-009, thanking SG13 for the information. Through the set ofIPCablecom recommendations, SG9 has defined an end-to-end QoS architecture for delivering IPservices over a cable network. SG9 invites SG13 to consider the QoS mechanisms defined inJ.163, Dynamic quality of service for the provision of real time services over cable televisionnetworks using cable modems, and J.174, Interdomain quality of service. These recommendationsdefine specific requirements for resource reservation, policy and policing, queuing and scheduling,and admission control. In addition, J.170, IPCablecom security specification, which definessecurity mechanisms for QoS signaling, should be considered.

TD-017, Progress on generic end-to-end QoS service requirements (Study Group 11), discusseswhether the protocol mechanism for end-to-end QoS service control should be based on QoSclasses and/or QoS parameters. SG11 would like to acknowledge the view of favoring the use of alimited number of QoS classes rather than QoS parameter values, based on the considerationsprovided in the different liaison responses. The liaison specifically asks for guidance from SG12and SG13.

TD-065 is a response to TD-017; it was sent to both SG11 and SG13. It notes that in theIPCablecom project, SG9 has defined mechanisms for an end-to-end QoS mechanism suitable foran architecture intended for the delivery of multimedia services across a network structure using aJ.112-based cable television network as access network. The mechanisms are based on negotiationof QoS parameters taking scalability issues into account. The work was successfully concludedand has resulted in a set of Recommendations that were brought to the attention of interested studygroups earlier.

TD-039, Transmitting Draft Rec. E.QSC (SG2), provides for information and comment DraftRecommendation E.QSC, Signaling of Proposed QoS Service Classes for IP-, ATM-, and ATM-Based Multiservice Networks. TD-071 is the response to TD-039.

Future Meetings

WG1 proposed that a Rapporteurs meeting for Questions 10 and 13 be scheduled for the week ofNovember 11, 2002 in Boulder, Colorado. Specific topics for discussion are expected to includeEmergency Telecommunications (draft supplement to J.160), Interdomain Communications(J.IDS), further work to draft amendment 1 to J.165, and any other significant relevant topics.



Working Group 2, Cable Modems

The WG2 chair is R. Yassini (YAS/CableLabs). WG2 covers the work in Q12/9 (Cable televisiondelivery of advanced multimedia digital services and applications that use Internet protocols [IP]and/or packet-based data). TD-090 is the report of this meeting. A Rapporteur meeting ofQuestion 12/9 is proposed for August 26-27, 2002 at a location to be announced.

TD-041 (Associate Rapporteurs for Questions 10, 12 & 13/9) is a summary of the status ofinternational cable modem and IPCablecom standards. No action was required based on thisinformative document. It is the intent of members of WG2 that the document be updated asstandardization activities progress in SCTE, ETSI, and ITU-T. TD-041 updates TD-48 of theprevious SG9 meeting in Dec. 2001.

J.191, IP Feature Package to Enhance Cable Modems, for “Consent”

COM 9-41 is draft amendment to Recommendation J.112 (Transmission systems for interactivecable television systems), Annex B, IP Enhanced Cable Modem-Feature Package (United States ofAmerica). WG2 reviewed COM 9-41, and it was decided to convert this proposed annex to astandalone Recommendation. Editorial changes were made in order to accomplish this goal.

Delegates requested harmonization of terminology within this proposal with terms contained withinCOM 9-43, Draft new Recommendation J.hna: Architecture of MediaHomeNet that supports cablebased services (see WG8, below), which was accomplished via editorial modifications.

TD-077 contains ITU-T draft new Recommendation J.191 – IP Feature Package to Enhance CableModems. J.191 provides a set of IP based features that may be added to a cable modem that willenable cable operators to provide an additional set of enhanced services to their customers includingsupport for IPCablecom Quality of Service (QoS), enhanced security, additional management andprovisioning features, and improved addressing and packet handling.

Recommendation A.5 documentation remains to be created for the following reference types:

• 30 IETF Standards (many of which are referenced within J.112)• 2 FIPS Standards (which are referenced within the IPCablecom Recommendations)

J.191, IP Feature Package to Enhance Cable Modems, was given Consent at the SG9 Plenary. TD-088 is a liaison to ITU-T SG15, ITU-R SG6 on draft new Recommendation J.191, noting that ithas been Consented at this meeting.

J.122, Second Generation Transmission Systems for Interactive CableTelevision Services – IP Cable Modem, for “Consent”

COM 9-42, Proposed draft Recommendation J.rfi2gen – Radio Frequency Interface 2.0 (UnitedStates of America), was reviewed. This recommendation defines the second generation ofradio-frequency interface specifications for high-speed data-over-cable systems and is in the familyof Recommendation J.112. Its purpose is to provide a technology through which the demand forsymmetrical services on cable networks can be met. This second generation technology, whileusing the same RF channel, is backward compatible with that of Recommendation J.112. Itprovides a significant increase in upstream channel capacity with wider channels, higher symbol rateand increased spectral efficiency. It provides for both Synchronous-CDMA and Advanced-TDMAcoding and also adds higher order modulation capabilities. It is more robust with regard to noiseimmunity and provides greater multipath protection than the technology used in Rec. J. 112.



Two options for physical layer technology are included, which have equal priority and are notrequired to be interoperable. One technology option is based on the downstream multi-programtelevision distribution that is deployed in North America using 6 MHz channeling, and supportsupstream transmission in the 5-42 MHz region. The other technology option is based on thecorresponding European multi-program television distribution and supports upstream in the 5-65MHz region. Both physical layer technologies are proposed to employ the same PMD technology.

The physical layer technology upstream Physical Media Dependent (PMD) sublayer uses anFDMA/TDMA (called TDMA mode) or FDMA/TDMA/S-CDMA (called S-CDMA mode) bursttype format, which provides six modulation rates and multiple modulation formats. The use ofTDMA [RF channel symbol rate (160 to 5,120 ksps)] or S-CDMA (modulation rate of 1,280 to5,120 kHz) mode is configured by the CMTS via MAC messaging. FDMA (frequency divisionmultiple access) indicates that multiple RF channels are assigned in the upstream band. A CMtransmits on a single RF channel unless reconfigured to change channels.

During the Working Group 2 meeting, it was proposed, since this document has undergoneconsiderable review in the industry and is a basis upon which demonstrably interoperable productsare being actively developed, that this contribution be considered for Consent at this meeting ofSG9.

WG2 discussed a number of editorial and minor technical changes to the regional differencesdefined in Annex F (European specification additions), and it was acknowledged that such changesmay be necessary to adequately define operation in certain regions.

Although it is anticipated that such changes may be necessary, it was decided by WG2 that thisdocument has been developed to a sufficiently mature state such that Consent is appropriate. Inlight of the fact that the details of the editorial and minor technical changes for Annex F have notbeen thoroughly vetted with interested parties outside of WG2, and to reduce the opportunity forconfusion that might arise should the text be posted for Last Call as-is, WG2 agreed that the currenttext of Annex F be replaced by placeholder text that will be replaced by working group participantsduring the last call period. The proposed placeholder text for Annex F is given in TD-086:

This Annex provides the changes necessary to be consistent with 8 MHz environments. Thecontent for this Annex is in the final stages of review by the relevant European industry and isin the process of submission for European standardization.

Recommendation A.5 documentation remains to be created for a number of references in thisdocument (many of which are referenced within J.112).

Working Group 2 recommends that this document, as amended by TD-086, be consented as J.122,Second Generation Transmission Systems for Interactive Cable Television Services – IP CableModems, with Last Call to be announced no sooner than September 2, 2002 to allow alladministrations adequate time to prepare comments. It was consented as such at the SG9 Plenary.TD-089 is a liaison to ITU-T SG15, and ITU-R SG6 on draft new Recommendation J.122, notingthat it has been Consented at this meeting.

WG2 Liaisons

TD-033, a liaison from SG15, requests that consideration be given to the suitability andrequirements for the transport of IPv6 Jumbo frames via GFP (Generic Framing Procedure -G.7041/Y.1303). TD-087, the response liaison, provides feedback on the suitability andapplicability to J.112 systems.



TD-034 is a liaison from SG15 requesting suggestions and comments on the revisedStandardization Plan and Work Plan for Access Network Transport (ANT), as well as commentsand suggestions for roadmapping future needs of access networks. No deadline was given foraction related to this liaison. Because the completion of such a roadmap for cable access networkswill require research and review, Working Group 2 took an action item to discuss the item via theQ12/9 email reflector as well as in the proposed Rapporteur’s Meeting, and to prepare a responsefor agreement at the subsequent SG9 meeting. TD-091, the response liaison, provides commentson the revised Standardization Plan, and informs SG15 of the intent to provide a road map table as aresult of the next SG9 meeting.

Working Group 3, Network Transport

The chair of WG3 is R. Kawaka (KDDI). The report of this meeting is TD-119. WG3 includesQuestions 1, 2, 11, 16, 17, 18 and 19:

Q1/9 Digital networks carrying sound-program signals for broadcastingQ2/9 Digital transmission of conventional television and high-definition television signals

for contributionQ11/9 Digital program insertion for MPEG-2 bitstreamsQ16/9 Transmission of multi-channel analog and/or digital television signals over optical

access networksQ17/9 Management and operational requirements with regard to wide area network edge

devices for TV and sound-program transmissionQ18/9 Transport of uncompressed studio quality TV, sound-program signals, and other

signals using the same interface on telecommunication networksQ19/9 Transport of video and audio signals over contribution or primary distribution

networks using IP techniques

J.133 (J.pcr), Measurement of MPEG-2 Transport Streams in Networks, for“Consent”

J.pcr_June_02 is draft new Recommendation J.pcr, Measurement of MPEG-2 Transport Streamsin Networks. MPEG-2 transport streams that are transmitted over any real networks are exposed tocertain effects caused by the network components which are not ideally transparent. One of thepre-dominant effects is the acquisition of jitter in relation to the Program Clock Reference (PCR)values and their position in the TS. This recommendation specifies measurements that enabledetermination of this jitter. TD-062 is the text that was given Consent as J.133 by the SG9 Plenary.

TD-063 is a liaison to SG15 and ITU-R WP6Q, noting that the new Recommendation J.133(J.pcr), Measurement of MPEG-2 transport streams in networks, has been consented.

J.187 (J.mpph), Transport Mechanism for Component-Coded Digital HighDefinition Television Signals Using MPEG-2 Video Coding Including All ServiceElements for Contribution And Primary Distribution, for “Consent”

COM 9-37 is text of draft new Recommendation J.mpph, Transport mechanism for component-coded digital high definition television signals using MPEG-2 video coding including all serviceelements for contribution and primary distribution (Japan). The scope of J.mpph is basically inaccordance with ITU-T Rec. J.89, which specifies the transport mechanism of SDTV. Threeeditorial errors were corrected.



J.mpph specifies the general transport mechanism for conveying all the service elements requiredfor contribution and primary distribution applications of TV programs whose vertical resolution isquite high compared to 525/60 or 625/50 television systems (e.g., 1125/60 system) using theMPEG-2 4:2:2 profile or Main profile at High level compression. The service elements provided toMPEG-2 coding systems are assumed to be (4:2:2) component video signals, studio quality audiosignals and various data signals, e.g., time code. J.mpph ensures the compatibility on the level ofthe bit-stream into a decoder. It is based on and is in conformity with the MPEG-2 standard ITU-TRecommendation H.222.0 | ISO/IEC 13818-1.

TD-023 (ITU-R Working Party 6P) is an incoming Liaison Statement on Draft NewRecommendation J.mpph. It commends SG9 because the draft new Recommendation specifies thetransport mechanism for resolutions higher than 525/60 and 625/50 television systems using theMPEG-2 coding 4:2:2 profile or Main Profile @ High Level.

The text given in TD-074 was Consented by the SG9 Plenary as J.187. TD-073, a liaison to ITU-R WP6A and WP6P, notes the Consent of J.187.

J.97 (J.metadata), Metadata on Cable Networks, for “Consent”

D.26 (Dec. 2001) is text for J.metadata, Metadata on Cable Networks. J.metadata defines therequirement that metadata used in Cable networks must allow for modification at the Cable Head-end by the controlling Cable network operator of that metadata received from an original source. Itwas Consented at this meeting by the SG9 Plenary as J.97.

A liaison to ITU-R WP6A, 6P, and 6Q is given in TD-115 and reports Consent for J.97.

J.189 (J.mbi), Seamless Splicing for MPEG-2 Bitstreams, for “Consent”

D.29 (Dec. 2001) provides text for J.mbi. J.mbi provides a seamless splicing technique forMPEG-2 bitstreams. Some modifications were made to the text and are reported in TD-104. D.29(Dec. 2001) plus TD-104 is J.189, Seamless Splicing for MPEG-2 Bitstreams, as Consented bySG9.

TD-107 is a liaison to ITU-R WP6M, notifying them of the Consent of J.189 (J.mbi).

J.metadata.req, Metadata Requirements on Cable Networks for Video-on-Demand

D.50, Proposed Draft Recommendation J.metadata.req, Metadata Requirements on cable networksfor video-on-demand (VoD, United States of America), describes requirements at the cableoperator’s headend for VoD metadata. While J.metadata denotes general requirements for cablenetworks, J.metadata.req focuses on VoD and lists specific tables.

A liaison to ITU-R WP6A, 6P, and 6Q is given in TD-114. It notes that J.metadata.req is expectedto be submitted for Consent at the next SG9 meeting.

J.89, Transport Mechanism for Component-Coded Digital Television SignalsUsing MPEG-2 4:2:2 P@ML Including All Service Elements for Contribution andPrimary Distribution (editorial revision)

D.49, Revision of Recommendation J.89, Transport mechanism for component-coded digitaltelevision signals using MPEG-2 4:2:2 P@ML including all service elements for contribution and



primary distribution (Japan), corrects editorial errors and inconsistencies in the current J.89. WG3proposed to the SG9 Plenary to include these corrections in an implementers’ guide.

WG3 Liaisons

TD-036 is a liaison from ITU-T SG15 about DVB encapsulation via GFP. It notifies SG9 that anamendment to G.7041 (Generic Framing Procedure) has received the Consent of SG15.

Working Group 4, Conditional Access and Webcasting

The Co-Chairs of WG4 are R. Prodan (Terayon) and S. Miyaji (KDDI). WG4 covers Question 6(Conditional access methods and practices for digital cable distribution to the home), 7(Requirements and methods for sound-program and television “webcasting” services), and 15(High-speed webcasting services over cable television networks). TD-078 is the report of thismeeting. No interim meetings have been requested.

TD-013 is a liaison from ITU-T SG16 on Recommendation J.121 (J.qweb), Quality controlprotocol for webcasting. It notes that QF/16 is working on a new Recommendation H.qos.mgtwhich will use similar techniques to those outlined in J.121. They would welcome being keptinformed of further developments. SG9 concluded that no action is required.

J.123 (J.mfweb), Multiplexing format for Webcasting on TCP/IP network, for“Consent”

COM 9-39 is proposed draft new Recommendation “Multiplexing format for Webcasting onTCP/IP network” (J.mfweb). This recommendation provides a multiplexing format appropriate foraudio and video transmission by download-based protocol over TCP/IP without any session controlprotocols between server and client. However, when session control protocols are not used, somenecessary information should be added to the media data. Therefore, this recommendation definesa multiplexing format particular to Webcasting on the TCP/IP. This format carries metadata, digitalrights management (DRM) information and formatted text as well as audio and video bitstreams.

WG4 made necessary editorial changes to COM 9-39. TD-056 is the revised version for Consentat this meeting. TD-056 also contains several new definitions on the multiplexing format which areproposed for the web list on definitions. TD-056 was Consented by the SG9 Plenary as J.123.

TD-081 is a liaison to SG16 and ISO/IEC JTC1/SC29/WG11 noting that J.123 (J.mfweb) hasbeen Consented. TD-079 is the Chairman’s letter to 3GPP2, noting the same thing.

Amendment to J.96, Technical Method for Ensuring Privacy in Long-DistanceInternational MPEG-2 Television Transmission Conforming to ITU-T J.89

D.52 (European Broadcasting Union), Proposed modification to Recommendation J.96 (Technicalmethod for ensuring privacy in long distance international MPEG-2 television transmissionconforming to ITU-T J.89 [Transport mechanism for component-coded digital television signalsusing MPEG-2]), provides a draft of Basic Interoperable Scrambling System with Encrypted keys(BISS-E). This draft specification describes a BISS-E for use on digital contribution circuits(satellite, DSNG, etc.) which use MPEG-2 compression, the DVB-S modulation scheme and theDVB Common Scrambling Algorithm with fixed keys. BISS-E uses encrypted Session Keys and



allows centrally-managed Conditional Access. It was noted that this specification can only be usedin conjunction with version 2 of the DVB-CSA when it becomes available.

WG4 reviewed D.52. As the technical specification attached to D.52 was in EBU style format, thedrafting group re-formatted and provided a new text as TD-072. The amendment to J.96 will beproposed for Consent at the next SG9 meeting.

TD-022, Compendia of Communication Systems Security (ITU-T SG17), was discussed. TD-022requests that SG17 (lead study group for security) be advised of any necessary modifications andadditions of the Compendia. WG4 agreed that the amendment to J.96 be proposed to be added tothe compendia. TD-111 is the liaison to SG17 proposing this. The Compendia is available(without password access) on the ITU web site at <http://www.itu.int/ITU-T/studygroups/com17/cssecurity.html>.

Working Group 5, Quality Assessment

The Co-Chairs of WG5 are A. Karwowska-Lamparska (National Institute, Poland) and A. Webster(US Dept. of Commerce). WG5 covers Questions 4 (Measurement and control of the quality ofservice for television transmission on contribution and distribution networks), 20 (Signal qualityparameters for MPEG-2 transport streams transmitted via telecommunication networks), and 21(Objective and subjective methods for evaluating conversational audiovisual quality in multimediaservices). TD-099 is the report of this meeting. A Rapporteur meeting of Questions 4/9 and/or21/9 is proposed to be held in early December 2002, location to be determined.

TD-101 is a draft liaison statement to ITU-R Working Party 6Q relating to draft newrecommendations prepared in ITU-T Study Group 9 WG5. It includes copies of J.146 (J.lpl, TD-050rev1), J.ists (TD-051 +corr1), J.ret (TD-052 +corr1+corr2), J.mmq-req (TD-098), and J.vqm(TD-097).

D.39 (Rapporteur on Question 4/9) is a report on progress in ITU-R WP 6Q concerning QualityAssessment. D.45 (Liaison Rapporteur to ITU-R SG6) is a brief report on the March 2002meeting of ITU-R SG6 (see Plenary report, above, for additional details).

TD-076 is a reply to ITU-R WP6Q’s meeting report liaison, supporting the content of theirpreliminary draft new Recommendation. WG5/9 considers that it will allow performance ofsubjective tests in a faster and less expensive fashion in the future. In that these gains may belimited to circumstances where the impairments are minor, modifications are suggested.

TD-053, Cooperation on measurement/monitoring of end-to-end quality (for action) (ITU-TSG12), notes that Recommendations produced by ITU-T Study Group 12, in particular with respectto subjective and objective end-to-end quality measurement techniques, have been used by otherITU-T Study Groups and are well accepted in the market. However, in some cases, measurementswere performed without consideration of the complete technical context, and consequently theresults were misleading. SG12 is currently considering whether these risks of misuse ofmeasurement techniques and mis-interpretation of results can be minimized by taking joint effortwith other Study Groups involved in these subjects. Therefore this liaison requests each involvedStudy Group to identify and to communicate those measurement issues that can best be resolved byjoint activities.

TD-102 is a response to SG12. SG9 notes that it currently has two Questions concerned withquality measurement, Questions 4 and 21. Question 4/9 deals primarily with television videoquality (Rapporteur A. Karwowska-Lamparska, Associate Rapporteur L. Durant). Question 21/9deals primarily with multimedia quality (Rapporteur A. Webster, Associate Rapporteur D. Hands).



Question 21/9 particularly welcomes the development of an active exchange of information withSG12. The liaison also includes a copy of J.mmq-req (see below).

TD-075 (Rapporteur for Q21/9) is a report on recent VQEG (Video Quality Experts Group)activities, including their February meeting in New York.

TD-055 (ITU-T SG12) notes that Recommendation G.114, One-way transmission time, will berevised to provide clear guidance on the effects of transmission time with respect to end-to-endspeech quality.

J.146 (J.lpl), Loop Latency Issues in Contribution Circuits for Conversational TVPrograms, for “Consent”

TD-037rev1 (March 2001) is the proposed text for J.lpl, Loop latency issues in contributioncircuits for conversational TV programs. The text was considered stable, and only minor changeswere made on the basis of ITU-R WP6Q comments. This Recommendation indicates that the looplatency in contribution circuits used for conversational TV programs can be annoying and can makethe resulting program subjectively unacceptable. The Recommendation presents results ofsubjective assessment tests on the perceptual impact of loop latency and gives its threshold ofacceptability.

TD-024 is a Liaison statement from ITU-R WP 6Q relating to draft new Recommendations (J.lpl,J.ists, J.mmq-req, J.ret). Regarding J.lpl, WP 6Q suggested:

• Can ITU-T SG9 include some details regarding where this recommendation would be used.E.g.:o A matrix relating to broadcast environments sensitive to loop latency.o Information extracted from subjective data to indicate potential advantages.

• Can the subjective results from Site C assessors be incorporated into the document?• Remove the codec table as it can lead to confusion, and focus on maximum delay value.

The Draft New Recommendation J.lpl, “Loop latency issues in contribution circuits forconversational TV programs” is given in TD-050rev1. This text was Consented by the SG9Plenary as J.146.

J.147 (J.ists), Objective Picture Quality Measurement Method By Use of In-Service Test Signals, for “Consent”

COM 9–R36 is Draft new Recommendation for objective picture quality measurement method byuse of in-service test signals (J.ists) (Japan). The text is stable.

This Draft Recommendation presents an objective picture quality measurement method by use ofin-service test signals in a digital television network. This method is separated into three procedures:

a) Test signal generation at the transmission side using the invisible marker methodb) Test signal detection at measurement pointsc) Picture quality measurement using the result of test signal detection

A practical implementation is described in Appendix I, while the parameters for generating in-service test signals and the performance of this method is described in Appendices II and III,respectively.



TD-024 is a Liaison statement from ITU-R WP 6Q relating to draft new Recommendations (J.lpl,J.ists, J.mmq-req, J.ret). Regarding J.ists, WP 6Q suggested:

1. Appendix 1 describes one practical implementation. It shall recognize that alternativeimplementations are possible.

2. Similarly, Appendix II and III refer to this particular implementation.3. Is it possible to extend this method to detect problems with the transmission stream (e.g., packet

headers, look-up table, etc.)?4. To what media is this applicable (e.g., between studios, broadcast to end receivers)?5. Can some indication of the overhead imposed by inserting the markers be provided?6. What is the lower intensity required for the marker to be useful (p.19)?7. Is it possible to watermark both the picture and the sound to ensure that:

• The correct audio and video is matched within a multichannel environment.• To ensure that audio and video are properly synchronized, and measure any asynchronies.

Only minor changes were made on the basis of ITU-R WP6Q comments.

The revised text is given in TD-051 and TD-051Corr.1, and was Consented by the SG9 Plenary asJ.147.

J.188 (J.ret), A Framework for an Efficient Duplex Video Transmission SystemIncluding Codecs With Functions of Failure Detection and Picture QualityEvaluation, for “Consent”

COM 9-38 is draft new Recommendation J.ret, A framework for an efficient duplex videotransmission system including codecs with functions of failure detection and picture qualityevaluation (Japan). Duplex transmission links including codecs are often set up to realize a highlyreliable contribution and primary distribution of television programs, in particular of big events suchas Olympics and World Cup Soccer. This configuration, however, has the following issues:

1. The reserve link is totally wasted during normal periods.2. Switching to the reserve link should be perfect to avoid a disrupted television program, when a

failure occurs in a transmission link.3. In addition, objective assessment of received video quality has been strongly demanded in an

actual operation of digital television program transmission.

This Recommendation, therefore, recommends a framework for methods that support solutions forthese issues. This framework mainly consists of the following three elements:

1. Efficiency: It reduces coding noise and improves picture quality compared to only one link byoutputting the average signal of two links, when both links are normal.

2. Support of failure detection: It detects a failure that occurs in one of the two links bymonitoring the two links by comparing them.

3. Automatic picture quality assessment: It evaluates the quality of the two decoded pictures bycomparing them.

Appendices show examples of methods in this framework. Such methods improve the operationalefficiency and reliability of duplex video transmission links.

TD-024 is a Liaison statement from ITU-R WP 6Q relating to draft new Recommendations (J.lpl,J.ists, J.mmq-req, J.ret). Regarding J.ret, WP 6Q suggested:

1. Amend the reference to 0 – not clear what it refers to.



2. Should the system also measure the quality after the averaging and switching process to test thatsystem has produced improved quality?

3. The following are not clear:• The practical use of the system.• Who should use it.• Can it be used to optimize the transmission path and is the delay induced by different paths

accommodated?

Only minor changes were made on the basis of ITU-R WP6Q comments.

The text given in TD-052, TD-052Corr.1 and TD-052Corr.2 was Consented by the SG9 Plenary asJ.188.

J.mmq-req, Requirements for an Objective Multimedia Quality Model

Draft new Recommendation J.mmq-req, Requirements for an objective multimedia quality model,was progressed. It is based on TD-084 from the Dec. 2001 meeting. The current version is foundin TD-098. It is expected to be proposed for Consent at the next meeting.

This draft new Recommendation details the requirements for the development of an objectivemultimedia perceptual quality model. The requirements are set out for an audiovisual model. Thecurrent requirements detail the form of the model, the focus for the multimedia modelingcomponent, and the nature of the output necessary for the model to operate as a valuable assessmenttool.

TD-024 is a Liaison statement from ITU-R WP 6Q relating to draft new Recommendations (J.lpl,J.ists, J.mmq-req, J.ret). Regarding J.mmq-req, WP 6Q noted that the Recommendation should beextended to include other forms of multimedia (e.g., IP).

J.vqm, Methodological Framework for Specifying Accuracy and Cross-Calibration of Video Quality Metrics

D.55, Suite of five technical reports describing methods of objective Video Quality Metrics (UnitedStates of America), was provided for information. The work of the Video Quality Experts Group(VQEG) has demonstrated the difficulty in obtaining an international agreement for adoption of asingle video quality metric (VQM). While this important work continues, there is a need formethods that quantify the accuracy (i.e., how well a VQM tracks subjective quality) and cross-calibration (how one VQM relates to another VQM) of existing VQMs being used by the industry.

D.55 provides the text of a series of five newly approved Technical Reports (TR) from ANSI-accredited Committee T1 that address this need. The first report provides methods and software forspecifying the accuracy and cross-calibration of VQMs. This TR also addresses how to specify thescope and limitations of a VQM. The algorithms and methods presented in this TR are general inthat they may be applied to any VQM or set of VQMs.

The remaining TRs contain associated information and methods used in the context of single andmultiple VQMs. The TRs deal with Normalization methods, PSNR, JND and facilitationMATLAB code.

D.54, Draft new Recommendation J.vqm, Methodological framework for specifying accuracy andcross-calibration of Video Quality Metrics (United States of America), notes that at the Decembermeeting of SG9, the USA provided an informational document (D.28) on methods that quantify theaccuracy (i.e., how well a VQM tracks subjective quality) and cross-calibration (how one VQM



relates to another VQM) of existing VQMs being used by industry. A similar contribution wasprovided to ITU-R SG6 WP6Q (document ITU-R 6Q/69) at their March 2002 meeting.T1.TR.PP.72-2001, Methodological Framework for Specifying Accuracy and Cross-Calibration ofVideo Quality Metrics, is a fully approved Technical Report (TR) from the ANSI accreditedCommittee T1. The present contribution has been modified from the approved TR with editorialchanges for international usage. It is proposed that this document be considered as the basis forITU-T and ITU-R recommendations for applications appropriate to each Sector. Because thiscontribution is being proposed for recommendations in both the ITU-T and ITU-R, it is stronglysuggested that liaison between ITU-T SG9 and ITU-R SG6 WP6Q be used to ensure the technicalaspects of the two proposed recommendations are mathematically equivalent.

TD-044 (Chairman of ITU-R WP 6Q) is a liaison statement to SG9 on D.54 and D.55. Thechairman of ITU-R WP 6Q offers information of ongoing work in WP 6Q as well as in VQEG, onmatters related to D.54 and D.55.

J.vqm provides guidelines for the development, documentation, preliminary validation, and use offull-reference video-quality metrics (VQMs). These guidelines include the following:

(a) Definition of the necessary elements in a full VQM disclosure.(b) An algorithm (based on statistical analysis relative to subjective data) to quantify the accuracy of

a given VQM.(c) An algorithm for quantifying a transformation between the output of any new VQM and the

output of any existing VQM.(d) Guidelines for documenting and specifying the limitations of a VQM.

The revised (current) version of J.vqm is found in TD-097. This Draft Recommendation isexpected to be proposed for Consent at the next SG9 meeting. It is expected to have commontechnical content with a parallel Recommendation in ITU-R WP6Q.

Working Group 6, Work Program, Questions and Liaisons

The WG6 Chair is S. Matsumoto (KDDI). WG6, Work Program, Questions and Liaisons,includes all the Questions of SG9. TD-080 is the report of this meeting.

SG9 Work Program

TD-003 summarizes the work program of Study Group 9 in 2002 – 2004, as of the beginning ofthis meeting (June 3, 2002). TD-041 presents an updated summary of the status of internationalcable modem and IPCablecom standards. The WG6 chair has confirmed with each WG chairman,and has updated the SG9 Work Program as described in TD-083.

SG9 Questions

COM 9-34 (Rapporteur on Questions) is a reminder to all SG9 Rapporteurs on dormant Questionsthat had been labeled as candidates for deletion. These Questions include:



Q. Title Rapporteur1/9 Digital networks carrying sound-program and television signals for

broadcastingY. Shavdiya (NIIR)

15/9 High speed “Webcasting” services over cable television networks S. Miyaji (KDDI)17/9 Management and operational requirements with regard to Wide Area

Network edge devices for TV and sound-program transmissionA. Ehbrecht (DTAG)

18/9 Transport of uncompressed studio quality TV, sound programsignals and other signals using the same interface ontelecommunication networks

H. Hoffmann (EBU)

Questions 1/9, 15/9, 17/9 and 18/9 received no contribution at the Study Group meetings of March2001, December 2001 and June 2002.

D.51, Proposal for a revision of Question 1/9 (Rapporteur on Questions), and D.58, Proposedrevision of Question 1/9: Advisable network and technical solutions for MPEG-2 signalstransmission over PDH and SDH networks (Russian Federation), propose the modification to theQ1/9 study subjects by focusing on the transmission of MPEG-2 multiplexes of television andsound program signals over PDH and SDH networks. WG6 has endorsed retaining Q1/9 with thismodification as described in TD-082. WG6 has also agreed to retain Q15/9, taking account of theRapporteur’s intention.

WG6 agreed with the suspension of Q17/9 and Q18/9 since contributions are not expected in thefuture and appropriate new rapporteurs are not available.

D.47, Cooperation between ITU and EDCF (United Kingdom), proposes to add the EuropeanDigital Cinema Forum (EDCF) to a list of cooperative organizations in the Annex of Q22/9,Transmission of D-cinema programs for contribution and distribution purposes. WG6 hasendorsed this proposal. TD-085 is the proposed revision of Question 22/9.

SG9 Liaisons

TD-019 (ITU-R WP 6M) provides the sixth revision of the working document for diagrammaticinter-relations of Recommendations for interactive broadcasting services and their summaries. TD-095 is WG6’s reply to WP6M, thanking WP6M for the information.

TD-020 is a liaison statement from SG17 announcing an ITU-T Workshop on Security held inKorea in May 2002.

TD-021 is a liaison statement from SG17 inviting SG9 to join the User Requirements Notation(URN) Focus Group; it requests comments on the content of their Draft Recommendation Z.150,User Requirements Notation. Because SG9 is not highly involved in the URN, WG6 decided totake no action.

TD-028 (SG4) requests comments on Recommendation M.3030, telecommunications Mark-upLanguage (tML) Framework. This Recommendation was Consented to AAP in April 2002 and isfollowed in a comment period with several months to final approval. Since SG9 is not highlyinvolved tML, WG6 decided to take no action.

TD-029, Update on the CORBA TMN Framework (ITU-T SG4), informs of small corrections andadditions to Recommendation X.780 on the TMN CORBA framework. No action was required.

TD-030, SG4 Report and Request in its role as Lead SG on TMN (ITU-T SG4), reports on theTMN project management meeting held in April 2002 and requests an appropriate expert from each



SG to review and update the TMN Documentation Plan. WG6 decided not to take any action dueto lack of experts in this field.

In addition to these liaison statements, one important liaison statement from TSAG onTelecommunication Reliability and Security (see TD-059 rev1 from the Dec. 2001 SG9 meeting,CSR 12.46) was overlooked at the last SG9 meeting. WG6 has agreed to send a liaison back toTSAG in order to inform of the appointment of E. Rosenfeld (Cable Labs, USA) as a contactperson for security studies, as shown in TD-096.

Working Group 7, APIs

The WG7 Chair is C. Sandbank (DTI). WG7 covers Question 5 (Interactivity over cable televisionnetworks) and Question 8 (Application programming interfaces [API] for services over cablenetworks). The report of this meeting is in TD-109. This report is also of interest to ITU-R 13/6.Members of JRG-1 were invited by the Chairman of SG9 to participate so that the work of JRG-1could progress at the same time. It is proposed to have the next meeting of JRG-1 September 1-4,2002, starting just before the 6M meeting.

D.46 (Chairman of JRG-1) is a progress report of JRG-1 to ITU-R WP 6M and ITU-T SG9. TheJRG-1 met March 18-20, 2002. The main activity built on the work of JRG-1 Subgroup 3 which isdescribed in Doc. 6M/117. This resulted in an important milestone document, Doc.6M/TEMP/49(Rev.1). Doc. 6M/TEMP/49(Rev.1) reports that the JRG-1 has receivedcontributions from a number of organizations specifying both Declarative and Proceduralfunctionalities for Interactive TV Applications. These are compared in Document 6M/117.The analysis in Document 6M/117 points to the possibility of significant harmonization of theProcedural Application Environments. The purpose of Doc. 6M/TEMP/49(Rev.1) is to distill andidentify these possibilities from the data specified by ARIB, ATSC-DASE, DVB-MHP and OCAP,noting that additional work is underway, e.g., DASE-2 and OCAP 2.0.

J.coreapi was created from Doc. 6M/117, Doc. 6M/TEMP/49(Rev.1[edited]), and Doc.6M/TEMP/55(edited). It was not Consented at this meeting. The Recommendation defines a“Common Programming Environment and Application Representation Format” that enablesinteroperability of applications for interactive television receivers. This represents the next stage indefinition under the umbrella of Rec. ITU-T J.200. It draws on analysis of both the syntacticdifferences and functional differences between five “Master Specifications” being developed orused by regional digital television systems (ATSC-DASE, DVB-MHP, OCAP, ARIB, andMHEG).

TD-040, Information on EBU/DVB work relevant to WG7 and JRG-1 (Chairman of SG9),provides a copy of a draft document from the DVB on MHP which is relevant to the work in SG9pertaining to Question 8/9 and the work that WG7 is carrying out on the development of aRecommendation for a Common Programming Environment and Application RepresentationFormat along with the JRG-1.

D.46 contains the current status of the comparison tables prepared by Vice-Chairman N.Yagi(Nippon Hoso Kyokai) and the JRG work plan with clarification of harmonization scope preparedby Vice-Chairman P. Griffis (Microsoft). It also contains proposals for progressing towards theharmonization of procedural and declarative content based on common core APIs extracted fromthe data submitted by ARIB, DASE, DVB-MHP and OCAP. These organizations had beencontacted before the SG9 meeting and asked for comment following review of the JRG outputdocuments by their own experts. The four responses are contained in Appendix A to TD-109.



Considerable further progress has been made on the harmonization of procedural content formatsparticularly with the help of a joint effort by ARIB, DVB and OCAP (soon to be joined by ATSC)who submitted a document entitled Globally Executable MHP (GEM). This supports the commoncore by providing semantic guarantees and system aspects of platform behavior. TD-067 (Q8/9) isa Liaison statement from DVB-MUG to JRG-1 on GEM.

TD-103 is a new draft Recommendation, Harmonization of procedural content formats forinteractive TV applications, for consideration as candidate for Consent at the next meeting.

Further progress has also been made on the related work towards harmonizing the declarativecontent for international program exchange; this work is still in a preliminary form, and requiressubstantial further interaction with the community contributing to the work of JRG-1. The currentstatus of this work is presented for information in TD-108.

Working Group 8, Set Top Boxes and Home Networks

The WG8 Co-Chairs are M Matsumoto (NEC, for Question 9/9) and J. Dahl (CableLabs, forQ14/9). WG8 covers Question 9 (Functional requirements for a universal integrated receiver orset-top box for the reception of cable television and other services) and Question 14 (The extensionof cable-based services over broadband in-home networks). The report of this meeting is TD-106(duplicated in TD-112). No interim rapporteurs meetings are proposed.

J.190 (J.hna), Architecture of MediaHomeNet that Supports Cable BasedServices, for “Consent”

COM 9-44 is the draft report of the Rapporteur’s meeting of the Experts on Question 14/9(Louisville, Colorado, USA, April 1-3, 2002, CSR 13.14).

COM 9-43 (Q14/9 Rapporteur) is proposed text for draft new Recommendation J.hna, Architectureof MediaHomeNet that supports cable based services. It is the principle output of the interimmeeting of Q14/9 that was held in Colorado, Louisville, April 1-3, 2002. The document wasreviewed in detail and several editorial improvements were made.

The goal of MediaHomeNet is to provide new cable-based services to devices within the home,complementing the J.112, IPCablecom, and cable broadcast network infrastructures. Specifically,MediaHomeNet provides an infrastructure, by specifying a home networking environment, overwhich IPCablecom and other related application services can be delivered, managed, and supported.Wherever possible, the architecture framework incorporates Recommendations and existingstandards.

The MediaHomeNet architecture composes two sub architectures: IPCable2Home architecture andProprietary architecture. The IPCable2Home architecture uses the Cable Modem (ITU-T J.112,2001) on the HFC network providing network capabilities. The Proprietary architecture uses thebroadcast services on the HFC network.

It is a goal of the IPCable2Home architecture to remain independent of physical and data linkprotocols. Home networking technologies such as G.989 (Home phoneline networkingtransceivers) are given as examples. The IPCable2Home architecture is focused on Layer 3 IPtraffic in the home. Similarly, IPCable2Home does not place requirements on higher layers forspecific application or codecs. However the architecture is designed to support resource intensiveservices such as MPEG video streaming, toll quality IP telephony, and gaming.



The MediaHomeNet architecture supports a myriad of operator and service provider businessmodels, and introduces additional features above and beyond current proprietary home networkingsolutions. One of the goals is the creation of an operator and service provider configurableResidential-Gateway-centric environment that will interact meaningfully with existing IP-basedhome devices (LAN IP Devices) and specified IPCable2Home devices. The MediaHomeNetarchitecture must allow for remote detection, access or control of services and applications on thehome network from either in-home or out-of-home.

The edited document is TD-060rev1. It was Consented by the SG9 Plenary as J.190.

WG8 prepared a liaison statement to be sent to ITU-T SGs 13, 15, 16 and ISO/IECJTC1/SC25/WG1, notifying them that J.190 (J.hna) has been Consented. The liaison statement iscontained in TD-105 (reproduced also in TD-113).

J.stb, Functional Requirements for the New Generation of Set Top Boxes forCable Television and Other Services

D.57 (Rapporteur for Q9/9) is a proposed draft new Recommendation, J.stb, Functionalrequirements for the new generation of STB for the reception of cable television and other services.Revised text is contained in TD-100 along with a list of issues. While the work is very preliminary,and no technical agreements have been reached, several members have expressed an interest inadvancing the work rapidly.

Working Group 9, D-cinema

The WG9 Chair is P. Zaccarian (Italy). WG9 covers Question 22/9 (Transmission of D-cinema[Digital Cinema] programs for contribution and distribution purposes), The report of this meetingis TD-070.

TD-042 (Rapporteur for Q22/9) is a progress report on Question 22/9 activities during the interimsince the last SG9 meeting.

TD-006, Liaison on Digital Cinema on Coding of moving pictures and audio (Convenor, ISO/IECJTC1), provides two documents for review, in regards to a digital cinema compression standard:

• Request for Industry Contributions: MPEG Standard for Distribution of Digital CinemaTheatrical Content (N4462)

• Digital Cinema “Expert Viewing” Test Methodologies (N4458)

The reply liaison is in TD-059. SG9 thanks ISO/IEC JTC1/SC29/WG11 and ITU-R SG6 (TaskGroup 6/9) for the documents, and notes the new work in ITU-T Q22/9.

D.45, Brief report on the March 2002 meeting of ITU-R SG6 (Liaison Rapporteur to ITU-R SG6),notes that work on D-cinema in SG6 has started in earnest with the recent setting up of Task Group6/9. The Task Group has produced an exceptional volume of activity at its first meeting, which hasresulted in the preparation of four preliminary draft new Recommendations, whose texts areexpected to be adopted at the SG6 meeting in September 2002:

• User requirements for D-cinema programs intended for distribution in cinema theatres• General reference chain and management of postprocessing headroom for program essence in

D-cinema applications• Expert viewing methods to assess the quality of visual material in D-cinema applications• Tools to evaluate candidate image systems for D-cinema applications



It should be noted that the two last Recommendations listed above are the counterpart of two listedfor Working Party 6Q, because the proponent Administration had submitted similar contributionsto both bodies, for action in their respective fields of competence. Task Group 6/9 has alsodeveloped an aggressive program of work for the forthcoming months, taking into account that allits studies on D-cinema should be completed in time to be adopted at the first meeting of StudyGroup 6 that will be held in 2004.

J.tdcine, Transport of D-Cinema Applications that Employ MPEG-2 EncodedHDTV Signals

D.48 (Italy) is a proposal for a draft new Recommendation J.tdcine, Transport of D-cinemaapplications that employ MPEG-2 encoded HDTV signals. This Recommendation specifiesapproaches to the transport of audio, video and data signals, for those D-cinema applications thatemploy HDTV signals encoded in conformity with MPEG-2 specifications. It is based on the useof specifications detailed in existing ITU-T Recommendations in the J-series.

TD-057 is revised text for J.tdcine. Working Group 9 agreed that the draft new Recommendationwould be proposed for Consent at the March 2003 meeting of Study Group 9.

TD-058 is a draft liaison to ITU-R Task Group 6/9 on ITU-T SG9 ongoing work on D-Cinema,noting the new work on J.tdcine. A copy of TD-057 is attached to the liaison.
