ABSTRACT:
A sampled color video signal is recorded in component form in a plurality of channels. The form of the signal is chosen so that if only one channel is available due to dropouts upon playback, then at least approximate separation into color components is possible, and if all channels are available, then full color separation is possible. The form is also chosen to provide a dynamic range that fits the transmission channel.
