摘要

The disclosed invention is a enhancement to the Video Encoder component of t he MPEG standard to improve both the efficiency and quality of the video presentation at the display device (Fig. 2). The inventions described below pertains to the enhancement of video compression technology (290). In genera l, they are compatible with MPEG video standards, but represent novel enhancements thereof (230). The above inventions apply to several transmissions media and networks including cable, DSL, wireless, satellite a nd IP networks (285). Another category of invention in this disclosure enhances networking performance by recognizing that the transmitted information is video, rather than data (271). This invention can be scaled to other classes of multimedia data such as speech or audio or images (234).
