A Motion-Compensated Interframe Coding Scheme for Television Pictures

Abstract

A motion-compensated prediction system for interframe coding is proposed. An interframe coding system is developed using this prediction method and second-order temporal prediction. Real-time hardware of reasonable circuit size using this coding system for monochrome TV pictures has been constructed. Assessments have been made of the picture quality of coded/decoded pictures from a variety of broadcast television programs. Quality was good for almost all such programs. A subjective test of picture quality was performed under stringent conditions, using some of the most difficult scenes selected in earlier experiments.
