【Abstract】 The paper introduced the main performance and structure of ADSP-BF561. The method of the extraction of the TV-tracking position deviation in a symmetrical background was described in detail. According to the experiment result based on the target video in PAL, the method can extract the tracking position deviation in time. And it was achieved to capture and display the video using the double-buffers mechanism.更多还原
