摘要： The video control circuit is particularly adapted to multimedia applicati, wherein image transmission services are offered in addition to usual telephone speech and data transmission services. The circuit is capable of processing both photographic and graphic video images, satisfying both the relevant CCIR standards and the specifications proper to personal computers, VGA EGA, etc. so as to allow the representation of either types of images on an only type of display. To this end, it generates both timings proper to the CCIR standards, for a resolution of 720 columns per 480 lines, with an upper representation limit of graphic planes of 1024 columns per 1024 lines.
