ABSTRACT:
A video signal recording apparatus is capable of compressing the amount of information of a video signal sequentially containing a plurality of pictures correlated to one another. In this compression, the video signal recording apparatus can selectively assume an intrapicture coding mode for executing compression by using only a correlation within each of pictures of the video signal and an interpicture coding mode for executing compression by using a correlation between a plurality of pictures of the video signal. When a video signal the amount of information of which is compressed is to be recorded on a recording medium, the video signal recording apparatus starts recording with a video signal compressed in the intrapicture coding mode. When a video signal compressed by variable-length coding is to be recorded while sequentially forming a multiplicity of tracks on a recording medium, the video signal recording apparatus begins recording a picture to be recorded immediately after the start of recording, at the forefront of the tracks.
