Abstract:
1. A device comprising: compression means for compressing a video signal by a data compression method using predictive coding; writing/reading means for performing a process of writing compressed data obtained by the compression means to a recording medium and a process of reading already recorded compressed data from the recording medium; control means for controlling the compression means and the writing/reading means so that the compressed data already recorded on the recording medium is not used for compression encoding of the video signal to be newly recorded; and receiving means for receiving an input indicating a selected mode upon starting the recording of the video signal, the mode being selected between one mode where the compressed data already recorded on the recording medium is not used for compression encoding of the video signal to be newly recorded and the other mode where the compressed data already recorded on the recording medium is read out and is used for compression encoding of the video signal to be newly recorded, wherein when the mode where the compressed data already recorded on the recording medium is read out and is used for compression encoding of the video signal to be newly recorded is selected, the control means controls the compression means and the writing/reading means to read out the compressed data already recorded on the recording medium and use the read-out data for compression encoding of the video signal to be newly recorded.
