PURPOSE: A device for processing a digital video signal is provided to record audio data in a part of an area where video data are recorded in an SD-DVCR(Standard Definition-Digital Video Tape Recorder), so as to extend the number of audio channels. CONSTITUTION: A video ADC(Analog-to-Digital Conversion) unit(410) converts a video signal into a digital signal. A video shuffling unit(420) shuffles video data outputted from the video ADC unit(410). An audio ADC unit(440) converts an audio signal into a digital signal. An audio signal processor(450) performs signal processing in a predetermined format for audio data, for shuffling. A video signal processor(430) performs compression signal processing for the video data shuffled in the video shuffling unit(420), and records additional audio data outputted from the video shuffling unit(420) in a spare space. An ECC(Error Correcting Code) unit(470) performs error correction for the audio data and video data, outputted from the video signal processor(430) and the audio signal processor(450).
