ISDB (Integrated Services Digital Broadcasting) has been studied for the future digital broadcasting system which will provide multi-program and multi-media services. To investigate into video coding system suitable for ISDB, an SDTV video codec and a variable bit rate program multiplexer have been developed. They conform to various services through a flexible service planning which ISDB makes possible. They also support low delay operation and error resilience, which are the necessary features for broadcasting. A variable bit rate control is very advantageous in efficient program multiplexing. Multi-program and multi-media transmission experiments, linked with ISDB system, have been successfully carried out to verify the expected functions and performance.
