ABSTRACT:
A video processor for generating an improved video display by synthesizing high frequency components of a received video signal in a manner that the frequencies of the synthesized high frequency components are greater than the upper frequency limit of the received video signal. A selected higher frequency band of the received signal modulates a continuous wave signal having a selected frequency so that the upper sideband frequency components of the modulated output are greater than the video signal upper frequency limit. The lower sideband components of the modulated output are removed and the upper sideband components are then added in phase with the original video signal to generate a composite signal having a greater bandwidth than the original received signal for generating the improved video display.
