MPEG OSD ANIMATED 'ON-SCREEN' DISPLAY PROVISIONS FOR AN VIDEO SIGNAL PROCESSING SYSTEM

摘要

A digital television system according to the present invention for processing television information in the form of a stream data packet representing video and audio information compressed by a method such as MPEG, So as to display an elaborate graphic such as an animation. The graphic data is transmitted to the same video decode and decompression unit that processes the video data contained in the video packet to form a digital signal representing the video information of the uncompressed form, As shown in FIG. A multiplexing arrangement is provided so that the digital signal representing the animated graphic is multiplexed into a digital signal representing the static graphic image data extracted from the bitmap representation.
