Patent ID: 6873368

Claim:
A method for processing first and second video signals respectively exhibiting first and second dissimilar image formats, comprising the step of detecting the presence of said first or second video signal, and further comprising the steps of: A. when said first video signal is detected, (a) converting said first video signal to a different format, to produce a converted signal; (b) filtering said converted signal to produce a filtered signal; (c) reconverting said filtered signal to the original format of said first signal, to produce a reconverted signal; (d) converting said reconverted signal to a lower resolution to produce a lower resolution, signal; (e) encoding said lower resolution signal to produce an encoded signal; and (f) conveying said encoded signal to an output channel; and B. when said second video signal is detected, (g) filtering said second video signal to produce a filtered signal; (h) converting said filtered signal to a lower resolution to produce a lower resolution signal; (i) encoding said lower resolution signal to produce an encoded signal; and (j) conveying said encoded signal to an output channel.
