An MPEG2-based digital CATV and VOD system using ATM-PON architecture
Proposes a next-generation access network infrastructure from NTT (Nippon Telegraph and Telephone Corporation.) The solution for providing both broadband and narrowband multimedia services is the ATM-PON (ATM-passive optical network) based FTTH (fiber-to-the-home) access network. Additionally, an MPEG-ATM encoder has been developed in order to provide CATV (cable TV) and VOD (video-on-demand) services in a fully-digital residential network. This is a compact, economical and easily-maintained multi-channel MPEG2 encoder, which is designed with custom LSIs for MPEG2 encoding and single-board circuits for each channel. NTT has been examining these systems in residential broadband service trials since January 1996. An outline of the trials and major features of the systems are presented.
