A study on high efficiency coding of HDTV at 50 Mbps

High-efficiency techniques for encoding HDTV signals at 50 Mb/s are proposed. An adaptive chrominance interpolation method and an adaptive chrominance decimation method are discussed. It is shown that the distortion of decimation can be decreased and visible distortion can be reduced. Some pictures using these schemes were encoded by computer simulation, and it was confirmed that the processed pictures are adequate for consumer use.<
