ABSTRACT:
A luminance component of a video signal is modulated in a first frequency band. A first chrominance component of the video signal is modulated in a second frequency band and is mixed with an audio component. A second chrominance component of the video signal is modulated in a third frequency band. The modulated luminance component, the first modulated chrominance component, and the second modulated chrominance component are then transmitted across a communication link.
