Abstract:
1. A recording apparatus for recording to a record medium a digital video signal of which a screen is divided into first blocks in a predetermined manner, a luminance signal and two color difference signals of each first block being divided into second blocks corresponding to a chroma format based on the ratio of sampling frequencies of the luminance signal and the two color difference signals, in the digital video signal, the luminance signal and the two color difference signals having been compression-encoded for each second block, the recording apparatus, comprising: detecting means for detecting a first chroma format that represents the ratio of sampling frequencies of the luminance signal and the two color difference signals of an input digital video signal; and controlling means for stopping a process for the input digital video signal in a period corresponding to the difference between a predetermined information amount represented by a second chroma format and the information amount represented by the first chroma format when the information amount represented by the first chroma format is smaller than the information amount of the second chroma format corresponding to the first chroma format detected by said detecting means.
