Abstract
Abstract A digital video and audio signal recording and/or reproducing device comprises: a recording format having a first recording area for recording a coded video signal, a second recording area for recording a coded audio signal, and a third recording area for recording an audio associated data constructed in pack form; means for coding the video signal and recording it in the first recording area; means for coding the audio signal and recording it in the second recording area; means for forming in pack the audio-associated information inserted in a vertical blanking period of the video signal and recording it in the third recording area; means for reproducing the coded video signal from the first recording area and coding the video signal; means for reproducing the coded audio signal from the second recording area and coding the audio signal; and means for reproducing the audio-associated information formed in pack from the third recording area and reading out the associated information.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
159 words
A digital video and audio signal recording and/or reproducing device comprising: a recording format having a first recording area for recording a coded video signal, a second recording area for recording a coded audio signal, and a third recording area for recording an audio associated data constructed in pack form; means for coding the video signal and recording it in said first recording area; means for coding the audio signal and recording it in said second recording area; means for forming in pack the audio-associated information inserted in a vertical blanking period of said video signal and recording it in said third recording area; means for reproducing the coded video signal from said first recording area and decoding the video signal; means for reproducing the coded audio signal from said second recording area and decoding the audio signal; and means for reproducing the audio-associated information formed in pack from said third recording area and reading out said associated information.
Claim 2
Dependent Claim
59 words
A digital video and audio signal recording and/or reproducing device according to Claim 1, wherein the third recording area has a major zone and a sub-zone, records the audio-associated information in the sub-zone of said third recording area and said audio-associated information having a high degree of importance is recorded in the main zone in said third recording area.
Claim 3
Dependent Claim
84 words
A digital video and audio signal recording and/or reproducing device according to Claim 2, wherein when the content of the sub-zone can be understood during a reproducing operation, the associated information in said sub zone is superposed on the vertical blanking period of the video signal and in turn when the content in the sub-zone can not be understood, only the associated information in the major zone having a high degree of importance is superposed on the vertical blanking period of the video signal.
Claim 4
Dependent Claim
48 words
A digital video and audio signal recording and/or reproducing device according to Claim 3, wherein a pair of tracks recorded by a pair of heads having different azimuth angles to each other are handled as pair and the kind of the associated information in the sub-zone is increased.
Claim 5
Dependent Claim
52 words
A digital video and audio signal recording and/or reproducing device according to Claim 4, wherein the most preference associated information is recorded in the sub-zone of the final track pair within 1 frame, thereby even if other associated information are recorded in the sub-zone of other track pairs, their convertibility is assured.
