ABSTRACT:
A video signal to be recorded on a recording medium used in a video tape recorder or optical disk recorder is digitized, distributed into several bit sets, and then subjected to separate processings or converting operations. The bit sets are merged into a data word with the same number bits as of the original digital data and, after being processed for bit inversion at a certain data interval, it is recorded on the recording medium. Data words retrieved from the recording medium are processed for bit inversion and inverse conversion in a reverse order with respect to the recording process, and a high quality video signal including a smaller number of bit errors can be reproduced.
