Abstract

The data structure includes a navigation area of a computer readable medium storing navigation data associated with a data stream representing a portion of at least one reproduction path. The navigation data includes indication information, and the indication information indicates whether the data stream represents multiple reproduction paths or the data stream represents a single reproduction path. If the indication information indicates the data stream represents multiple reproduction paths, the navigation data includes path number information and an indicator associated with each reproduction path. The path number information identifies a number of the multiple reproduction paths, and each indicator indicates a file associated with the associated one of the multiple reproduction paths.

Claims

1. A computer readable medium having a data structure for managing reproduction of a data stream, comprising:

a navigation area storing navigation data associated with a data stream representing a portion of at least one reproduction path, the navigation data including indication information, the indication information indicating whether the data stream represents multiple reproduction paths or the data stream represents a single reproduction path, and if the indication information indicates the data stream represents multiple reproduction paths, the navigation data includes path number information and an indicator associated with each reproduction path, the path number information identifying a number of the multiple reproduction paths, and each indicator indicating a file associated with the associated one of the multiple reproduction paths.

2. The recording medium of claim 1, wherein the navigation data further includes information associated with seamless reproduction if the indication information indicates the data stream represents multiple reproduction paths.

3. The recording medium of claim 2, wherein the indication information has a first value or a second value, the first value indicating the data stream represents multiple reproduction paths, and the second value indicating the data stream represents a single reproduction path.

4. The recording medium of claim 1, further comprising:

a data area storing at least one clip file of the data stream, each clip file representing one of the multiple reproduction paths if the indication information indicates the data stream represents multiple reproduction paths.

5. The recording medium of claim 4, wherein the multiple reproduction paths represent multiple camera angles of video data.

9. The method of claim 1, further comprising;

recording at least one clip file of the stream data in a data area of the recording medium, each clip file representing one of the multiple reproduction paths if the indication information indicates the data stream represents multiple reproduction paths.

6. A method of recording a data structure, for managing reproduction of a data stream, on a recording medium, comprising:

recording navigation data associated with a data stream representing a portion of at least one reproduction path on the recording medium, the navigation data including indication information and at least one indicator, the indication information indicating whether the data stream represents multiple reproduction paths or the data stream represents a single reproduction path, each indicator indicating a file associated with a reproduction path; and

selectively recording path number information as part of the navigation data on the recording medium based on the indication information, the path number information identifying a number of the multiple reproduction paths.

7. The method of claim 6, wherein the navigation data further includes information associated with a seamless reproduction if the indication information indicates the data stream represents multiple reproduction paths.

8. The method of claim 7, wherein the indication information has a first value or a second value, the first value indicating the data stream represents multiple reproduction paths, and the second value indicating the data stream represents a single reproduction path.

10. A method of reproducing a data structure for managing a data stream, comprising:

accessing navigation data associated with a data stream representing a portion of at least one reproduction path, the navigation data including indication information and at least one indicator, the indication information indicating whether the data stream represents multiple reproduction paths or the data stream represents a single reproduction path, each indicator indicating a file associated with a reproduction path;

selectively accessing path number information from the navigation data based on the indication information, the path number information identifying a number of the multiple reproduction paths; and

reproducing the data stream based on the accessed navigation data.

11. The method of claim 10, the navigation data further includes information associated with a seamless reproduction if the indication information indicates the data stream represents multiple reproduction paths.

12. The method of claim 10, wherein the indication information has a first value or a second value, the first value indicating the data stream represents multiple reproduction paths, and the second value indicating the data stream represents a single reproduction path.

13. The method of claim 10, further comprising;

reproducing clip files of the data stream, each clip file representing one of the multiple reproduction paths if the indication information indicates the data stream represents multiple reproduction paths.

14. The method of claim 13, wherein the multiple reproduction paths represent multiple camera angles of video data.

15. An apparatus for recording a data structure for managing a data stream, comprising:

a driver for driving a recording device to record data on a recording medium, and;

a controller for controlling the driver to record navigation data associated with a data stream representing a portion of at least one reproduction path, the navigation data including indication information, the indication information indicating whether the data stream represents multiple reproduction paths or the data stream represents a single reproduction path, and if the indication information indicates the data stream represents multiple reproduction paths, the navigation data includes path number information and an indicator associated with each reproduction path, the path number information identifying a number of the multiple reproduction paths, and each indicator indicating a file associated with the associated one of the multiple reproduction paths.

17. An apparatus for reproducing a data structure for managing a data stream, comprising:

a driver for driving an reproducing device to reproduce data from a recording medium, and;

a controller for controlling the driver to read navigation data associated with a data stream representing a portion of at least one reproduction path, the navigation data including indication information, the indication information indicating whether the data stream represents multiple reproduction paths or the data stream represents a single reproduction path, and if the indication information indicates the data stream represents multiple reproduction paths, the navigation data includes path number information and an indicator associated with each reproduction path, the path number information identifying a number of the multiple reproduction paths, and each indicator indicating a file associated with the associated one of the multiple reproduction paths.
