説明

This paper describes a new signal processing method for MUSE encoders and decoders which improves Hi-Vision pictures. Seven years have passed since MUSE was first developed as an HDTV broadcasting system. Many experiments have proved that MUSE is a practical system. Although the picture quality of MUSE is sufficient for practical use, it is still possible to improve it further. Our new signal processing method improves the picture quality of the moving areas. In addition, we have been studying how to improve picture quality of the stationary areas as well, which means extending the resolution and attenuating aliasing noise. Based on this research, we have built a new MUSE encoder and a new MUSE decoder. They are highly compatible with the conventional MUSE system.
