The new frontier created by high-bandwidth digital video systems and services

Digital broadcasting services provide high-definition TV service and an increased number of standard definition TV channels. The allocated bit-stream rate, however, is around 30 Mb/s/channel, whereas original digital video signals require 100 to 1000 Mb/s. MPEG2 is used to compress the original source data to a rate suitable for broadcasting and recording. The compression codings are shown for digital video systems, together with computing power required for decoding. Advanced LSI technology with sophisticated architecture and device technology will enable high-bandwidth video systems. Performance improvement by a factor of two per year is possible. Availability of such advanced video systems will create various new business frontiers with sophisticated video applications such as the 3DCG game linked with Live TV, the multi-angle TV program and the video filtering to customer profile. This in turn will provide a large market opportunity for semiconductor business.
