    Abstract

    The authors discuss an experimental 64-kb/s video codec that transmits still and motion pictures in several coding modes. In previous work (1986), they proposed a coding scheme, tailored to 384-kb/s transmission, that used motion-compensated prediction and hybrid quantization and a 64-kb/s video codec design concept having several coding modes. Here, they detail the computer simulation used to check the proposed coding scheme's efficiency at 64 kb/s. They then describe the hardware architecture that implements the design concept. The performance of the video codec is then demonstrated in different coding modes.
