ABSTRACT:
A noise reduction circuit in a recording medium player is disclosed in which the time-axis of a video signal read out from a memory to be used for noise reduction is changed by a shift command signal for changing the time-axis of a video signal in order to keep the continuity of the phase of a color burst in special playback operation. Owing to the arrangement, even in a special playback operation, the phases of a chrominance signal and a luminance signal contained in a read out video signal, and those of a chrominance signal and a luminance signal contained in a video signal as a signal to be mixing-processed coincide with each other, which makes it possible to prevent the blur in a played back picture.
