ABSTRACT:
A method of selectively recording one of plural kinds of video signals having different frame (field) rate and the accompanied sound signal comprises the steps of: converting one of plural kinds of video signals and the sound signal into another digital signal; generating the error check codes from the digital signal; recording the digital signal and the generated error check codes on a recording medium, wherein one of a plural kinds of video signals and the digital sound signal are converted and the error check codes are generated to have the same data rate between the plural kinds of video signals to form the same M tracks (sectors) for the same interval on the recording medium between the plural of kinds of digital video signals. The error check codes are generated every N tracks (sectors), the M being natural number more than one: N being a divisor of the M. Sequence number data is generated and recorded on the recording medium together with the another digital signal and the generated error check codes every track (sector).
