SeaChange powers H.264 HD IPTV on-demand service

June 16, 2006

Japan's OnDemand TV is launching an IPTV on-demand service to offer high-definition programming encoded in the H.264 video compression standard. The transition is being done with existing VOD technology from SeaChange.

Beginning in July, subscribers around Tokyo and Osaka will have access to on-demand libraries of HD movies, sports and other programming. The programming will be encoded with MPEG-4 AVC (H.264) compression, a standard that enables delivery of HD video streams in less than half the bandwidth required by MPEG-2.

The OnDemand service, which has used SeaChange's IPTV Systems since early 2005, continues to deliver MPEG-2 streams for standard-definition movies and programs in conjunction with the range of new H.264-encoded HD choices. The existing SeaChange platform supported the expansion to H.264.

At its commercial launch in March 2005, OnDemand TV delivered service over IP v6 fiber optic networks, taking advantage of the SeaChange IPTV System's capabilities for delivering multiple media formats and bit rates.

SeaChange's IPTV System automates entire on-demand services from ingest to set-top applications. It combines fault-resilient and scalable SeaChange MediaCluster servers with Axiom video operation system software, which manages sessions and resources for all video network functions.
