CSC (Communication Service Concierge)NTT Cyber Solutions Laboratories
With the explosive increase in popularity of broadband and mobile network access in recent years, the connection of things
to the Internet that have never before been considered is beginning. We are also seeing rapid diversification in the ways
networks are employed by users. CSC is network middleware that serves as a platform for providing user-friendly services that
respond to the needs of this new network society.
In CSC, communication appliances that are connected to a network are configured with software components known as
plug-in modules. Network appliances include home gateways, automobiles, cell phones and other such devices that are
connected to a network. The required plug-in modules can be downloaded to the communication appliance from a data center to
immediately replace or add to existing plug-ins (1) when adding new services or devices, (2) when customizing functions for
individual customers, or (3) when it is desired to correct problems, download. CSC can be used in various fields, including home
automation, home security, ubiquitous services, mobile appliances, energy conservation, healthcare, telematics, and education.
CSC conforms to the industry standard OSGi* (www.osgi.org) specifications, with extended functions for better security and
providing safer services as well as functions for flexible cooperation among peer appliances. NTT promotes standardization
activities in the OSGi Alliance and established the OSGi Users’ Forum Japan (www.osgi-ufj.org) with other companies to
popularize this technology in Japan.
We will continue with future research and development to achieve even safer and faster provision of appealing network
services with CSC.

Music Discernment System via Mobile PhoneNTT Information Sharing Platform Laboratories
By a user transmitting a song heard on a street, from a radio or television to a data center via a mobile phone, this “music
discernment system via mobile phone” can identify the name of the song and inform the user of the name via e-mail.
In October 2004, in collaboration with NTT Resonant Inc., NTT Laboratories performed field test of the music discernment
system via mobile phone at “in the city Tokyo 2004”, a music industry event. After we had evaluated service requirements and
technical matters, the system was launched commercially in December 2004 as a mobile service provided by the Internet portal
site “goo”.
By combining “media research technologies” and “service integration technologies” developed at NTT Laboratories, this
system becomes a large-scale call-center system with outstanding customizability for mass-user services. Utilizing media-
search technology, it extracts characteristic data (i.e., a “fingerprint”) from a sound source sent from a mobile phone, checks a
previously prepared, huge database of fingerprints at high speed, and identifies the musical composition contained with the
sound source. Moreover, by utilizing service integration technology, mutual cooperation between multiple groups of
servers — such as CTI* servers and search servers for checking pairs of fingerprints — is possible. As a result of utilizing this
technology, a large-scale system can be constructed, while maintaining customizability, in a short time period from many
hundreds of systems. Maintenance such as database update adding new releases coming out day by day is available without
stopping the service.
From now onwards, we plan to apply the music discernment function to fields other than mobile phones, such as
broadcasting, we hope to expand the business domain of the NTT Group, such as copyright management business.

NTT-CERT, as the CSIRT for NTT GroupNTT Information Sharing Platform Laboratories
Information security cannot be pursued only by proactive protection measures. Moreover, since information systems mutually depend on
each other through multiple types of interactions over information network, it is difficult for an individual group, organization or person in charge
to execute effective security measures. With the aim of overcoming this difficulty, the activities of CSIRTs*1 and coordination among them have
been drawing much attention. The key factors for success of these activities are to construct and maintain capabilities for collecting incident
information and leading-edge trends commoditize know-how and delivery usable information in the right place at the right time.
The NTT Laboratories — R&D center to develop an information-security platform within the NTT Group — founded NTT-CERT*2 on October
2004 and started CSIRT activities since then. At the core of the NTT Group, NTT-CERT is a trusted contact point of NTT Group in regard to
information security and through which organizations and specialists inside and outside of the NTT Group can cooperate and receive reliable
back up regarding early incident detection, early incident resolution, limiting damages, and prevention. Put more concretely, NTT-CERT
analyzes security information collected from CSIRTs inside and outside of NTT Group, and develops advisories and technical documents in
the forms reusable at the scene of operation and delivers this information to appropriate place timely. On January 2005, NTT joined FIRST*3 or
Forum for Incident Response and Security Teams which is the worldwide CSIRTs alliance working on developing and coordinating member
CSIRTs all over the world in terms of exchanging security information and coordinated incident response worldwide, in order to tighten
relationship with other CSIRTs all over the world, since the security breaches and incidents nowadays can easily spread out worldwide.
From now onwards, NTT-CERT will develop a security management framework called “NTT CRISTs” for CSIRTs and the security
departments in NTT Group companies to share the security information and to manage incidents and their response. NTT-CERT will continue
to support establishing a CSIRT at NTT Group companies for their own, coordinating CSIRTs within NTT Group, and communicating with
other CSIRTS out of NTT Group.

Examples of how i-Visto is used
The i-Visto Internet HDTV Video Studio SystemNTT Network Service Systems Laboratories, NTT Network Innovation Laboratories
As evidenced by the beginning of terrestrial digital broadcasting in 2003, the transition in television broadcasting from analog
to digital format is being accompanied by a rapid shift toward multiple channels and higher image resolution. This trend has
presented broadcasters with the major problems of how to efficiently produce high definition television (HDTV) programs, which
require five times as much data as conventional standard definition television (SDTV) and distribute the programs to affiliated
stations across the nation.
NTT Laboratories have developed i-Visto*1 to provide an environment for producing and distributing high-quality HDTV
material at low cost to broadcasting industries. The i-Visto system functions as an integrated network system that implements,
for the first time, realtime transport, storage, and distribution of uncompressed multi-rate HDTV video up to 1.5 Gbit/s over an IP
network whose maximum speed is 10 Gbit/s.
Some research results and activities from 2004 are listed below.
(1) April 2004: Success in live, two-way uncompressed HDTV via a commercial 2.5-Gbit/s IP network between Japan and the U.S. at NAB*2 2004.
(2) August 2004: Success in live, uncompressed HDTV over a 10-Gbit/s IPv6*3 network between Osaka and Tokyo.
(3) November 2004: Successful transmission of up to six multiplexed uncompressed live HDTV signals using a video synchronization technique between Chiba, Tokyo, and Osaka over a 10-Gbit/s IP network at InterBEE*4 2004.
(4) February 2005: Remote conferencing with uncompressed HDTV video over a 10-Gbit/s IP network between Kanagawa and Osaka.
(5) March 2005: Successful uncompressed live HDTV transmission between the World’s Exposition site (in Aichi) and Osaka.
(6) March 2005: Successful development of a server system capable of storing and distributing uncompressed HDTV at up to 15 Gbit/s.
We will continue to expand this system with respect to network computing, including storage functions.

Container Administrative Experiment by Using Active RFID TagsNTT Network Innovation Laboratories
The NTT Laboratories are turning attention to Active RFID* as a key device for implementing distribution management and
automatic freight movement history recording. An Active RFID contains its own battery power supply for transmitting a radio
signal. Active RFID Tags that are already on the market emit weak signals periodically, but the NTT Laboratories have developed
a more powerful RFID that offers more advanced features.
We conducted verification experiments for marine shipping container management with the Active RFID. We attached our
400-MHz Active RFID to containers and measured the signal range. Even in a container yard where containers were stacked
around in the area, the signal could be read at about 30 m from the RFID. These results demonstrate the feasibility of recording
of freight movement histories in unprecedented detail by using this high-performance Active RFID on freight containers.
In future work, we will proceed with development and experimentation on highly accurate location determination technology
and various types of sensor network technology to achieve a more practical and efficient system.
