ABSTRACT:
A video data recording/reproduction method used in a VTR, wherein distribution of picture elements into channels is altered for each field or frame so that the same picture element arrangement produced by interpolation does not continue in successive fields or frames, and wherein information indicating the type of picture element arrangement is recorded together with the video data. The method is intended to perform interpolative correction for still picture portions without sacrificing the resolution, while retaining the editing functions in units of field or frame, whereby degradation of a reproduced picture can be minimized.
