Patent ID: 7030934

Claim:
A video system for combining a first analog video signal with a second analog video system to generate a combined analog video signal, the video system comprising: a multiplexer having a first input port, a second input port, a control port, and an output port, wherein the first input port is coupled to receive the first analog video signal and the output port is configured to provide the combined analog video signal; a video processor coupled to receive the second analog video signal and to generate a processed analog video signal and a switch signal, wherein the video processor is configured to change the resolution of a plurality of images from the second analog video signal to form a plurality of scaled images; to pad the plurality of scaled images with pad data to form a plurality of padded images having a resolution equal to a resolution of a plurality of images in the first analog video signal; and to form the processed analog video signal with the plurality of padded images; and wherein the switch signal is provided to the control port of the multiplexer and the processed analog video signal is provided to the second input port of the multiplexer.
