摘要：
According to the present invention, when an ATV signal is recorded by a digital VCR in the conventional television signal record mode, variable speed reproduction data composed of HP data containing I frame is redundantly recorded in a surplus record area that is formed by the difference between the transmission rate of the ATV signal and the transmission rate of the conventional compressed digital video signal. When variable speed reproduction is performed, the variable speed reproduction data is reproduced.
