ABSTRACT:
A color TV signal playback apparatus capable of applying H (horizontal sync) period compensation and color sequence compensation to a color TV signal stored in a magnetic tape. A 1-H delayed reproduced color signal and a non-delayed reproduced color signal are switched from one to the other in response to a color sequence compensating signal. The selected reproduced color signal is multiplexed with a reproduced luminance signal to prepare a composite video signal. A signal produced by delaying the composite video signal by a period of time equal to a deviation in the period of a horizontal sync signal and the non-delayed composite video signal are selected in response to an H-period compensating signal, thereby producing a compensated color TV signal.
