US Patent 7162531 Manipulating a compressed video stream

A computer may be remotely accessed. At a first location, display commands are generated. The display commands are converted into a compressed video data stream. Each display element (50) is checked if it is encoded (52). If an object is encoded, it is transcribed into MPEG (54). The image is adjusted for display (56) and compression (58). Additional steps of motion determination (60), change detection (62), compression depth and frame determination (66, 68) are executed. Then the data is transmitted to a second location. This display commands are decompressed and displayed as an image at the second location.
