Development of Multimedia Services for Current and Future Broadcasting Media

摘要

ISDB will be the infrastructure for future broadcasting services in the 'multimedia era' that will arrive with the new century. Basic characteristics such as the multiplexing of various kinds of program component signals and the transmission of multiple program TV signals have been tested by using the MPEG-2 based experimental system. Since ISDB has a very high potential, studies have to continue to examine the feasibility of more sophisticated functions, while at the same time there should be a gradual introduction of basic multimedia services using current broadcasting channels to gain experience in program production as well as in the utilization of these new services by users.
