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

机译:MPEG视频信号处理系统的动画“屏幕上”显示规定

摘要

A digital television system which processes television information in the form of a stream data packets representing video and audioinformation in compressed form, such as MPEG, includes on-screen display (OSD) provisions for displaying sophisticated graphics, suchas animation, by storing graphics data in a read only memory (ROM) in the same compressed form as that used for the video information.The graphics data is transported to the same video decoding and decompression unit which processes the video data contained in the videopackets to form digital signals representing video information in uncompressed form, where it is converted in the same manner as the videodata to form graphic image data. A multiplexing arrangement is provided so that digital signals representing animation graphics can bemultiplexed with digital signals representing static graphics image data derived from bit-mapped representations.
