    摘要: A method of dubbing compressed digital video signals (32) adopted for an apparatus (1-15) for efficient coding and subsequent recording/playback of video signals. In the method of dubbing compressed digital video signals, on a playback unit side (8-15), after padding error data by an error processing circuit with respect to an error uncorrectable in error correction by an ECC circuit (10) of playback, the digital video signal is provided with a parity for transmission by a parity generating circuit (6) and is then transmitted to a recording unit side (1-7). On the other hand, on the recording unit side (1-7), after padding error data by an error processing circuit with respect to an error uncorrectable in error correction by an ECC circuit (10) of transmission, the digital video signal is provided with a parity for recording by a parity generator (6) and is then recorded in a recording medium.
