Abstract

The authors consider the problem of bandwidth reduction needed to allow HDTV (high-definition television) signals to be transmitted through the narrow DBS (direct broadcast by satellite) channel and to simultaneously fulfil the compatibility requirement with the European DBS transmission standard, the MAC/packet family. This problem is studied in the context of the EUREKA 95 project. The HDMAC coding system is outlined; it is a three-mode system (stationary 80 ms, tracking 40 ms, and dynamic 20 ms modes) with motion compensation used in the 40 ms mode. The system was built in hardware and has been demonstrated
