Coding of Broadcast TV Signals for Transmission Over Satellite Channels

This paper presents the coding algorithms and simulation results of multimode movement-compensated interframe video coders operating at 15 and 20 mbits/s for broadcast applications. The coding algorithms are based on a motion-compensated predictive coding approach. Simulation results using samples of broadcast video sequence indicate that excellent picture quality is obtained at the 20 Mbit/s transmission bit rate. Results of informal subjective evaluation of picture quality are also presented.
