Digital Transmission of HDTV via CS using MPEG2 CODEC

This paper describes a transmission system for Hi-Vision (HDTV) program materials. The system consists of an HDTV coder-decoder (codec) using MPEG2, a Trellis-coded 8PSK* modem (TCM) and other equipment. Using the system and a Communication Satellite (CS), we realized a program transmission route which enables us to use various images and sounds sent from field broadcasting points.
