Abstract

Video data divided into a plurality of cells, attribute information for specifying the playback order of the plurality of cells, and a flag for specifying whether the playback can be effected or not for each of the plurality of cells are recorded on an optical disk. In a playback apparatus, the cell which is specified to be inhibited from being played back by the flag is not played back when a plurality of cells are played back based on the playback order specified by the attribute information.

Claims

1. An optical disc on which video object data and control information for controlling the video object data are recorded, wherein a recording/reproducing apparatus accesses data of the optical disc in accordance with the control information, the optical disc comprising:

a data area configured to store the video object data, the video object data including a plurality of groups of pictures; and

a management area configured to store the control information, the control information including a plurality of program chains including cells, wherein,

each of the cells is configured to enable management of a reproducing period of the video object data,

each program chain is configured to enable management of a reproducing order of the cells, and

a cell of one part of the program chains and a cell of another part of the program chains are configured to enable overlap playback of a same portion of the video object data.

2. A method for reproducing video object data and control information recorded on an optical disc including,

a data area storing the video object data, the video object data including a plurality of groups of pictures, and

a management area storing the control information, the control information including a plurality of program chains including cells, wherein,

each of the cells is configured to enable management of a reproducing period of the video object data,

each program chain is configured to enable management of a reproducing order of the cells, and

a cell of one part of the program chains and a cell of another part of the program chains are configured to enable overlap playback of a same portion of the video object data,

the method comprising:

reproducing the control information from the management area; and

reproducing the video object data from the data area.

3. A reproduction apparatus for reproducing video object data and control information recorded on an optical disc including,

a data area storing the video object data, the video object data including a plurality of groups of pictures, and

a management area storing the control information, the control information including a plurality of program chains including cells, wherein,

each cell is configured to enable management of a reproducing period of the video object data,

each program chain is configured to enable management of a reproducing order of the cells, and

a cell of one part of the program chains and a cell of another part of the program chains are configured to enable overlap playback of a same portion of the video object data,

the reproduction apparatus comprising:

a first reproducer configured to reproduce the control information from the management area; and

a second reproducer configured to reproduce the video object data from the data area.

4. An information recording method for recording information on an optical disc including,

a data area configured to store video object data, the video object data including a plurality of groups of pictures, and

a management area configured to store control information for controlling the video object data, the control information including a plurality of program chains including cells, wherein,

each cell is configured to enable management of a reproducing period of the video object data,

each program chain is configured to enable management of a reproducing order of the cells, and

a cell of one part of the program chains and a cell of another part of the program chains are configured to enable overlap playback of a same portion of the video object data,

the information recording method comprising:

recording the video object data and the control information on the optical disc.
