Method of coding and transmission of progressive video using differential signal overlay

摘要

A method of coding and transmission of a 1080p or other higher resolution picture using a lower resolution differential signal overlay on top of a lower resolution existing video signal. The method may be useful for television service providers or other video related application providers in that the use of the lower resolution signals may allow the providers to utilize existing capabilities while providing a higher resolution picture.

1. A method of simulating a 1080p signal, the method comprising:
transmitting a first 1080i signal with motion vectors; transmitting a second 1080i signal with less motion vectors than the first 1080i signal; and enabling simultaneous decode of the first and second 1080i signals, the simultaneous decode of the first and second 1080i signals forming the 1080p signal.
