A new set of LSI chips have been developed to construct Clearvision receiver system. Main digital Signal processings are Motion Adaptive 3-Dimensional Y/C-separation and Motion Adaptive 3-Dimensional Scan Conversion. These processings enhance picture quality for NTSC color TV signals. processing functions have been integrated in three LSI chips. It is Possible to rationalize scale of system,these LSI have included Line-memories and D/A converters.
