HDVC initiative and LTE as an enabler forHD Video communication on IMS




Traditional room based videoconferencing

Many proprietary solutions that work only in closed

environments. Mainly intracompany or intercompany

(through operator’s service centres)

Tele-Presence Services

For a niche of Top customers.

Need strong infrastrucural and networking

requirements. Mainly Intracompany.

Market growth opportunities for Operators…

Videocommunication adoption extended

also to the Consumer Market

Tablet/Smartphone diffusion

video-client HDTV-IP introduction

(es. Sony, Samsung, ecc), at limited

expenditures

Reduced bandwidth capacity tosupport HD Videocommunication

IP-based control platforms for VoIP

services (IMS) are «natively» video-

ready




…and market growth limits

Although video services demand is growing (e.g. video in Skype traffic is > 50%),

the videoconferencing market is constrained by several factors:

lack of interoperability among networks and manufacturers

closed solution environments

Complexity in switching between networks and/or video equipment from

different manufacturers located in different countries

Costly single vendor solutions can target only high profile corporate

customers

Need to unite a fragmented and non-interoperable market

place by involving players from the ITC sector to create a

common set of standards based on openness and

interoperability

HDVC




What is HDVC (High Definition Video Conference)?

5

+

•COMMUNITY (reuse of traditional fixed & mobile telephone numbers)

•EASY TO USE & ACCESS (many access – many device: TV/PC/Tablet/Smartphone LTE)

•QUALITY (managed service)

•INTEROPERABILITY (any device – to – any network; any provider – to – any provider)

•COST SCALABILITY (economies of scale for device and network equipment)

Effort of an open group of operators and equipment manufacturers to apply existing

and emerging open standards to high quality video communication

HDVC technical profile is based on 3GPP IMS

… More Operators & Vendors are welcome to join us!!

HDVC mission

Provide business and consumer customers with easy to use,interconnected, and interoperable high quality video conferencing services

globally.

Define minimum profiles of features from existing standards for the user

to network and network to network interfaces.

Validate the profiles through the demonstration of interoperable video

conferencing across multiple operators and utilizing equipment from multiple

vendors.

Encourage the participation of additional operators, service providers,network suppliers, and equipment manufacturers that are aligned with and

actively contributing towards the mission.

HDVC profile

The UNI / NNI documents are a profile (i.e. a minimum set

of functions that all equipment must support) of the

SIP/IMS specifications,

covering e.g.

SIP registration

HDVC strenghts

End to End interoperability - UNI profiling ensures interoperabilty

between any networks and any device; NNI profiling ensures

multivendor/multicarrier interoperability

Identities - Operators can choose whether to reuse traditional

telephone number (e.g. TEL:+391721234512) or SIP-URI (e.g.

name@operatordomain). Reuse of E.164 simplifies user experience.

Same platform as Voice over IMS – HDVC reuses the samenetwork infrastructures Operators will launch for mobile and fixed

telephony (IMS). The main difference is the introduction of the MRF

(conference focus) to handle point-to-multipoint services.

Open interworking to other solutions - NNI profile can be used as

a global reference for interconnection between networks

implementing different videocomunication solutions.

Basic service concept - Point to Point, Ad-hoc conferencing, Meet-

me, Content Sharing in conference, supplementary service support

(Originating/Terminating Identification Presentation, …)

HDVC on LTE

The bandwidth requirement is of 2 Mbit/s for 720p and 4 Mbit/s for 1080p. Thebandwidth can be reduced adopting H.264 High Profile. This profile isn’t available on

portable device.

End-to-End QoS is needed for large deployment to guarantee the bandwidth on radio

interface.

A bidirectional-simmetrical bandwidth requirement. Latency: Apart from large bandwidth requirements, a small round trip time is

required for reduced delays between frames. Any delay beyond 150-300ms becomes

noticeable and distracting.

HDVC service specifically require LTE access to be delivered on mobile networks.

Remarks

HDVC identifies “only” a technical profile (on top of standards capability), necessary

for UNI & NNI interoperability.

Standards (3GPP, HDVC) are essential but not sufficient for service enablement. The

following operational aspects were intentionally left out of profiling activity, but will

need to be addressed:

QoS assurance (over fixed access and at interconnection)Commercial settlement between Operators

NAT/Firewall traversal

Scheduling & management facilities

Consistent dial plan

Device Certification

Conclusions

Today there are different Videoconference Systems but there are still many problems to define afully interoperable service like the GSM ones.

IMS can be considered as and enabler to develop a fully interoperable Videoconference service

between different Telcos.

Telecomitalia and other operator, network equipment providers and terminal provider have

worked in GSMA to define HDVC service profile to be integrated in IR.39.

This profile define also the IP interconnectivity based on IPX and NNI SIP interconnection

between Telcos based on TS. 29.165.

The idea of HDVC as Open Forum where different Telcos, Network Equipments Provider and

Terminal provider can participate to implement this approach.
