Audio visual coding technologies and LSI circuits based on MPEG2 standard to implement multimedia services

Abstract

Summary form only given, as follows. Standardization of MPEG2 has been almost completed and it is expected to be the most important technology for fascination multimedia services in telecommunication, broadcasting and interdisciplinary services areas. The MPEG2 coding algorithm for video and audio signals is outlined and the main features of the MPEG2 standard are presented. The LSI technology required to implement functions for MPEG2 is described, and the current status of the development for LSI chips in the world is touched upon. Finally some pilot systems in Japan to provide multimedia services using MPEG2 standard are introduced.
