PC type Receiver for 525-line Interlace/Progressive Digital Broadcast

Abstract

This paper describes a PC type Receiver for 525 line progressive/interlaced scanning (525p/i) digital broadcast. The graphic overlay onto 525p picture has not been realized in a conventional PC receiver. We have achieved PC graphics overlay onto high quality 525p picture as well as 525i picture by implementing Matsushita's proprietary video decoder LSI for 525p/i and a specially designed graphics accelerator. A front-end module is also implemented.
