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.
