The Digital Micro-mirror Device (DMDTM) and the Digital Light Processing (DLPTM) system utilizing the DMD are used in various types of image projectors, and are now being applied to high-definition television (HDTV) projection systems. Terrestrial HD digital broadcasting service began in the USA in 1998, and satellite HD digital broadcasting is scheduled to start in Japan in DEC 2000. The 720 P-DMD (horizontal pixel number : 1280, vertical pixel number : 720, mirror pitch : 13.8 pm) was developed for consumer HD projector applications to display full extent of broadcast High Definition television. In 1999, a prototype 720 P-DLP rear-projection system was made with the 720 P-DMD. This paper describes the 720 P-DLP system and its digital signal processing technique.
