An HDTV broadcasting service on one satellite broadcast channel became available after the development of a transmission system called MUSE involving bandwidth compression. Using MUSE, a satellite channel of width 27 or 24 MHz in the 12 GHz band can carry an HDTV picture, digitally-coded four-channel sound and independent digital signal at about 100 Kb/s.

Abstract HDTV broadcasting, which uses a multiple sub-sampling method, is being conducted in Japan on an experimental basis. In this paper, we discuss a new method to improve the picture quality of the HDTV broadcasting system. We are proposing a new signal processing method for chrominance signals in moving areas. The concept of this method is to process the chrominance signal frame by frame. Here, we will refer to the MUSE system as an example of an HDTV broadcasting system, however it is easy to adapt the idea to other HDTV systems.
