Abstract
An improved definition TV (IDTV) digital broadcast receiver is described that uses three-dimensional digital signal processing with motion-adaptive Y/C signal separation and motion adaptive scanning video line interpolation techniques in order to improve the picture quality of the NTSC system circuitry in use. The receiver uses seven large scale integration chips that include 11 image field memories and 12 scan line memories. After a brief review of the function of each clip, the digital processing system is examined along with the motion adaptive Y/C separation method. >
