Abstract: This article discusses the addition of motion compensation to an earlier motion-adaptive bandwidth reduction system. The earlier system reduced the bandwidth of a high-definition television (HDTV) signal by a factor of four and was capable of transmitting a highly detailed image in stationary parts of the picture. However, loss of resolution in moving areas was an objectionable artifact, which would become increasingly obvious in an HDTV transmission system as the performance of cameras and display devices improved. The addition of motion compensation, with the aim of being able to transmit signals with high spatial resolution in all parts of the picture except those whose motion cannot be estimated accurately, significantly improved the quality of the decoded picture, although at the expense of the compatible picture quality.
