ABSTRACT:
In order that each of two recording channels utilized for a single color television signal may be used if necessary to provide a complete picture with only a loss of quality, digitally coded signal samples of the luminance signal and of the two chrominance signal components are equally distributed between the two channels, successive luminance component samples going alternately to the two channels, each pair made up of related samples of the two chrominance components going entirely to one channel or the other, with successive pairs going to different channels. With the usual input sequence, a simple transposition of the sample sequence in one channel can make the sequences of the various components in the two channels identical.
