ABSTRACT:
The digital signal recording apparatus of the invention for recording a video signal on a recording medium, includes: a mode setting section for setting a recording mode, the recording mode being one of a standard recording mode and a long-time recording mode having a longer recording time than that of the standard recording mode; a sampling section for sampling the video signal at a sampling number corresponding to the recording mode set by the mode setting section, the sampling number when the selected recording mode is the long-time recording mode being smaller than the sampling number when the selected recording mode is the standard recording mode; a coding section for coding the video signal sampled by the sampling section at a compression rate corresponding to the recording mode set by the mode setting section, the compression rate when the selected recording mode is the long-time recording mode being higher than the compression rate when the selected recording mode is the standard recording mode; and a recording section for recording the video signal coded by the coding section on a recording medium.
