The transmission of HDTV signals on digital networks requires adoption of sophisticated compression techniques to limit the bit-rate requirements and to provide a high-quality and reliable services to customers. This paper describes system design and transmission characteristics of an adaptive subband DCT codec that can encode original 1.2 Gb/s HDTV signals at 156 Mb/s. The performance of the codec was evaluated using motion picture signals. The characteristics obtained with the codec was found to maintain good picture quality.
