Abstract
There is provided a digital information signal recording and reproducing apparatus which is arranged to input a plurality of kinds of digital video signals, generate sub-information indicative of a television system of the digital video signal, and form a track on a recording medium to record the digital video signal and the sub-information related to the digital video signal at predetermined locations on the track, respectively.
Claims16
A digital signal recording apparatus for recording a digital video signal and a digital audio signal on a recording medium transported by transporting means, comprising:
- (a) sub-information generating means for generating digital sub-information including a first signal indicating at least one of the different types of television signal formats of the digital video signal and a second signal representing at least one of a plurality of recording mode each of which has different transporting speed of the recording medium;
- and
- (b) recording means for forming a plurality of tracks on a recording medium transported by said transporting means to record the digital video signal and the digital sub-information in each of the plurality of tracks,
- said recording means recording adjacently the first signal and the second signal in each of the plurality of tracks.
A digital signal recording apparatus for recording a digital video signal and a digital audio signal on a tape-shaped recording medium transported by transporting means, comprising:
- sub-information generating means for generating digital sub-information including a first signal representing at least one of the different types of television signal formats of the digital video signal and a second signal representing at least one of a plurality of recording modes each of which has different transporting speed of the tape-shaped recording medium;
- and
- recording means for forming a plurality of helical tracks on a tape-shaped recording medium transported by said transporting means to record the digital video signal and the digital sub-information signal in each of the plurality of helical tracks,
- said recording means recording adjacently the first signal and the second signal in each of the plurality of helical tracks.
