Abstract
We describe a tnotion-compensated hybrid DCT/DPCM video compression scheme that incorporates arithmetic coding. The scheme is based on a current ISO/CCITT standards proposal for compressing still images with suitable extensions to handle video sequences. Compared to Iluffman coding, arithmetic coding can increase compression efficiency for the same image quality or, alternately, improve image quality for the same transmission rate. We have extended the use of arithmetic for coding motion vector data and motion-compensated interframe data. We have also investigated the trade-off in image quality, transmission bandwidth, and algorithm complexity between using I-Iuffman or arithmetic coding in motion video.
