Abstract
In audio contents which have cells for defining an audio title playback unit and whose actual playback sequence is determined by defining the playback sequence of the cells, cell information to specify the cells is provided with identification information to identify the types of the cells according to the difference in the contents of the data included in the cells. One type of the contents of the data in the cells is for obtaining the length of the silent period of time. The identification information corresponding to the cell indicates a silent cell.
Claims21
An audio data structure characterized in that, in audio contents which have cells for defining at least an audio title playback unit and whose actual playback sequence is determined by defining the playback sequence of the cells, identification information to specify the types of the cells according to the difference in the contents of the data included in said cells is included in cell information to specify said cells.
An audio data structure characterized in that, in a track that defines the playback sequence of one or more cell groups,
- an arrangement of audio cells composed of ordinary audio data items is allowed as a first arrangement, and
- an arrangement of silent cells composed of only audio data items with an amplitude level of zero and audio cells composed of ordinary audio data items is allowed as a second arrangement.
An audio data structure characterized in that, in a track that defines the playback sequence of one or more cell groups,
- the audio attributes of the cells constituting said track and track connection information indicating the relationship in playback time between the present track and the preceding track are provided between tracks.
A disk playback apparatus characterized by comprising
- an information recording medium which has cells for defining at least an audio title playback unit, audio contents whose actual playback sequence is determined by defining the playback sequence of the cells, and an audio data structure where identification information to identify the types of the cells according to the difference in the contents of the data included in said cells is included in cell information to specify said cells, with at least silent data existing in said cells and said identification information including silent cell identification information to identify said silent data cell, and
- means for reading the recorded information on said information recording medium and, when recognizing said silent cell identification information, supplying the audio contents integrated in the identification information to an audio decoder section.
A transmission apparatus characterized by transmitting such information as includes audio contents which have cells for defining at least an audio title playback unit and whose actual playback sequence is determined by defining the playback sequence of the cells, and causes identification information to identify the types of the cells according to the difference in the contents of the data included in said cells to be included in cell information to specify said cells, one type of the contents of the data in said cells being for obtaining the length of the silent period of time and the identification information corresponding to the cell indicating a silent cell.
A receiving apparatus characterized by comprising means which receives such information as includes audio contents which have cells for defining at least an audio title playback unit and whose actual playback sequence is determined by defining the playback sequence of the cells, and causes identification information to identify the types of the cells according to the difference in the contents of the data included in said cells to be included in cell information to specify said cells, one type of the contents of the data in said cells being for obtaining the length of the silent period of time and the identification information corresponding to the cell indicating a silent cell and which, when recognizing the identification information indicating said silent cell, supplies the cell integrated in the identification information to an audio decoder section for playback.
A recording medium on which audio contents are to be recorded, the audio contents having cells for defining at least an audio title playback unit and making actual playback sequence determined by defining the playback sequence of the cells, said recording medium characterized by recording identification information to identify the types of the cells according to the difference in the contents of the data included in said cells in such a manner that the identification information is included in cell information to specify said cells.
A recording medium characterized in that, in a track defining the playback sequence of one or more cell groups,
- an arrangement of audio cells composed of ordinary audio data items is allowed as a first arrangement, and
- an arrangement of silent cells composed of only audio data items with an amplitude level of zero and audio cells composed of ordinary audio data items is allowed as a second arrangement for recording.
A recording medium characterized in that, in a track defining the playback sequence of one or more cell groups,
- the audio attributes of the cells constituting said track and track connecting information indicating the relationship in playback time between the present track and the preceding track are recorded between tracks.
