ABSTRACT:
A recording and reproducing device for frequency division multiplexing of a television video and a digital data signal. The digital signal is interleaved in blocks so that the length of an interleaved block is longer than a video field but shorter than a video frame. The interleaved digital data is recorded so that an end of a group of blocks corresponds to a vertical synchronizing signal for the video signal.
