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. Realtime hardware of reasonable circuit size using this coding system for monochrome TV pictures has been constructed. Sampling frequency and bit-rate of this system are 10.06 MHz and 1.6 bits/pel, respectively. 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. The lowest value for the quality of pictures coded/ decoded at 1.6 bits/pel was 3.7 on a five-grade impairment scale.
