Method and apparatus for the processing of color video signals in which the two fields of a color video frame are compressed into a single field without appreciable loss of picture resolution and without image disturbance and degradation. The compressed signal may be recorded on a single track of a VCR and played back in a still-frame mode without picture jitter, color loss, or image degradation. According to the invention, first and second color video signals of a predetermined time period (such as a field period) are compressed into a time-division-multiplexed (TDM) signal of a single time period. The luminance components of the first and second signals are summed to produce a sum luminance signal and subtracted to produce a difference luminance signal, the sum signal having a greater bandwidth than the difference signal. A chrominance signal is produced which is a function of the chrominance components of the first and second signals. The luminance signals and chrominance signal are compressed and arranged sequentially to form a TDM signal of a single time period.
