■  Outline
YGV639 (hereafter referred to as “VC1E,” its function name) is the display controller which makes it easier to create a highly colorful graphic image in a low-cost system configuration. VC1E, having a build-in digital video decode, allows characters, lines, and graphic icons (hereafter, called “sprite”) to be superimposed over CVBS signal from a CCD camera. It is possible to represent moving images like animation even through a serial port communication, and VC1E realize impressively higher colorful picture expression under an equivalent CPU control load as that of a low-cost OSD controller.
