Abstract
Color television signals are split up to provide a luminance signal and a chrominance signal. These are recombined in a manner designed to reduce the frequency bandwidth and, furthermore, time-subdivision is used to distribute signals for recording between two channels, with time expansion being provided in each channel before recording each channel on a separate track on the recording medium. In playback, the signals of the separate channels are time-compressed and then sequentially switched back into the original signal sequence. The time-expansion and distribution among channels can be performed after the color television signal has been rearranged to occupy smaller bandwidth or the components of the television signal can be separately time divided, distributed and time expanded in the recording technique, with the converse signal processing being performed in playback.
