Abstract:
A digital signal recording and reproducing device comprising:high efficiency encoding means for encoding a digital video signal at a high efficiency and outputting video data encoded at the high efficiency;recording means for executing a predetermined encoding process for recording the video data encoded at high efficiency and outputted from said high efficiency encoding means and for recording video data obtained after the encoding process on a recording medium;reproducing means for reproducing the video data recorded on said recording medium executing a predetermined data processing on the reproduced video data and outputting the video data;delay means for delaying the video data outputted from said high efficiency encoding means by a delay time of a total of a delay time of the video data relevant to the processing of said recording means and a delay time of the video data relevant to the processing of said reproducing means, and for outputting delayed video data;selecting means for selectively switching over between video data outputted from said delay means and video data outputted from said reproducing means, and for outputting the selected one of the video data; andhigh efficiency decoding means for high-efficiency-decoding the video data outputted from said selecting means, and for outputting video data high-efficiency-decoded.
