Patent ID: 8634029

Claim:
A video processing system comprising: an RF signal input operative to receive a band of RF signals; a diplexer device having an input and first and second outputs, said input of said diplexer coupled to said RF signal input operative to provide first and second RF output signals of mutually exclusive channel frequencies from said band of RF signals at respective ones of said first and second outputs exclusively; a first tuner having a first tuner input coupled to said first output of said diplexer; a second tuner having a second tuner input coupled to said second signal output of said diplexer; and a video signal processor for generating a signal representing multiple images, said video signal processor having first and second inputs coupled to respective ones of first and second outputs of said first and second tuners, wherein said band of RF signals at said input of said diplexer include said first modulated channel signal at a first channel frequency and second modulated channel signal at a second channel frequency, said first modulated channel signal has a first signal power, said second modulated channel signal has a second signal power, said first output of said diplexer provides said first modulated channel signal at said first channel frequency with said first signal power for said first tuner being tuned to said first channel frequency, said second output of said diplexer provides said second modulated channel signal at said second channel frequency with said second signal power for said second tuner being tuned to said second channel frequency, said diplexer device further comprises first and second tunable filters, said first tunable filter is tuned to pass said first channel signal to said first output of said diplexer while blocking said second channel signal when said first tuner is tuned to said first modulated channel signal, said second tunable filter potion is tuned to pass said second channel signal to said second output of said diplexer while blocking said first channel signal when said second tuner is tuned to said second modulated channel signal.
