【Abstract】 The GO7007SB is a multi- format audio and video compression chip of the American WIS Technologies. The GO7007SB uses multiple algorithms to buffer and compress raw video data into streams. The output video stream can be MPEG- 1,MPEG- 2, MPEG- 4,MJPEG or H.263 format. This paper will introduce the application of GO7007SB chip on the MPEG- 4 Audio and Video Compression System with USB2.0 interface, and it includes three aspects――system structure, hardware design and software design.更多还原
