Abstract
A television-type video signal containing main information, and auxiliary information modulating an auxiliary subcarrier having a controlled phase, is applied to a field storage network. First and second adaptive luminance-chrominance separators of the line comb filter type are coupled to the field storage network for receiving input signals from adjacent image fields, respectively. Chrominance outputs from the separators are combined to produce a separated main chrominance signal. Luminance outputs from the separators are combined to produce a separated main luminance signal. The modulated auxiliary subcarrier is derived from the field storage network.
