Nationwide roll out of IPTV in Japan will include MPEG-4 technology from TANDBERG Television of Norway.
The MPEG-4 rollout includes using AVC IPv6.
"On Demand TV" — a joint venture of NTT West (Nippon Telegraph and Telephone West Corp. and Itochu — will expand its deployment of TANDBERG Television’s Mediaplex-20™-based video head-ends to support MPEG-4 AVC technology.
On Demand TV is planning to deploy TANDBERG Television MPEG-4 AVC transcoding in its Mediaplex-based head-ends in Tokyo (East) and Osaka (West). Each head-end will process transcoded MPEG-2 to MPEG-4 AVC content and deliver it to NTT’s Broadband (FTTH and ADSL) customers. On Demand TV also is adding two new Mediaplex head-ends to its existing installation of Mediaplexes to transcode the MPEG-2 content to MPEG-4 AVC and to provide additional head-end redundancy.
On Demand TV will use the MPEG-4 AVC transcoding technology to reduce the bit rate of video delivery over millions of its DSL lines and to offer a new, extensive library of video-on-demand (VOD) movies to NTT’s subscribers in both standard definition and MPEG-4 AVC High Definition VOD.
“After one year, our MPEG-2 IPTV service has been completely dependable and is operating well with the Mediaplex. We’re getting ready to expand our IPTV offering beyond our fiber networks and make it available to the rest of our subscribers over our ADSL networks, and TANDBERG Television’s MPEG-4 advanced compression and transcoding technology enables us to deliver high-quality content regardless of bandwidth constraints or content format,” says Yasuyuki Taniguchi, Chief Manager of Engineering for On Demand TV. “The Mediaplex video head-end’s efficient migration path to MPEG-4 will make it easy for us to upgrade our head-ends with a minimal amount of resources expended.”
NTT West and NTT East provide telephone and broadband services to more than 60 million subscribers across Japan, which has one of the world’s highest broadband penetration rates. On Demand TV currently delivers 27 broadcast channels over the NTT West and NTT East IPv6- based fiber networks using MPEG-2 compression.
TANDBERG Television is publicly traded (Oslo, Norway, Stock Exchange: TAT) and is a major supplier to digital broadcasters around the world, including the Australian Broadcasting Corp. (ABC), BBC, BSkyB, FOX Sports, NBC, NTL, Telenor and StarTV
