Abstract

This paper describes an efficient coding algorithm developed for the bit rate reduction of full motion video signals . The algorithm combines a motion adaptive subsampling process with a Discrete Cosine Transform (DCT) based digital coding method in order to achieve a compression factor greater than twenty without annoying artefacts. Thus images with Common Intermediate Format ( CIF ) can be coded at a bit rate of about 1,2 Mbit/s with a good quality. A version of this algorithm has been used for coding of some test sequences at 900 Kbitls. They have been presented to the Moving Picture Expert Group's ( MPEG) meeting held in Japan, October 1989.
