VIDEO SIGNAL PROCESSING UNIT

摘要

PURPOSE: To display an image of a full mode as a shape represented by an original image when the image is displayed on a television receiver whose aspect ratio is 4:3 having no aspect conversion function and the image is transmitted. CONSTITUTION: A video signal reproduced from a video disk 1 is subject to aspect ratio conversion processing at an aspect ratio converter 3 depending on a video ID detected by a video ID decoder 4 and a setting content of an aspect ratio conversion changeover button 6 and outputted through a switch SW 1. Then the video ID is rewritten depending on the aspect ratio conversion processing by a video ID encoder 7 and added to a video signal after aspect ratio conversion at a synthesizer 8.
