Abstract

An information storage medium on which multi-angle data is recorded includes at least two clips in each of which video object data for an angle of the multi-angle data is recorded. The at least two clips are recorded in contiguous areas of the information storage medium.

Claims

1. A method of recording motion picture data for different angles corresponding to a motion picture to an information storage medium, the method comprising:

recording clip information on the information storage medium; and

recording clip audio-video (AV) streams corresponding to the recorded clip information on the information storage medium, at least two of the recorded clip AV streams correspond to the motion picture data for different angles, and each of the at least two clip AV streams comprising a plurality of interleaved blocks, and the interleaved blocks included in one clip AV stream among the at least two clip AV streams are interleaved with the interleaved blocks included in the other clip AV streams among the at least two clip AV streams,

wherein;

each recorded clip information comprises an entry point map comprising;

information on entry points of a corresponding one of the recorded clip audio-video streams for random access, and

information on whether each of the entry points is an angle change point,

the angle change point is a point through which the motion picture is reproduced from one of the angles to another of the angles,

the clip information further comprises information on an address of the entry point map, and

a start point of the interleaved blocks is the angle change point.

2. The method of claim 1, wherein the information on the entry points comprises location information of the entry points among the AV streams.

3. The method of claim 1, wherein the information storage medium further comprises playlist information which comprises at least one playitem corresponding to the recorded clip AV streams.

4. The method of claim 3, wherein the at least one playitem comprises angle block information, and the angle block information comprises information on whether the playitem is for the motion picture data of the different angles.

5. The method of claim 4, wherein the angle block information further comprises information on a number of the different angles of the motion picture data of the different angles.

6. A method of reproducing motion picture data for different angles corresponding to a motion picture from an information storage medium, the method comprising:

reading clip information from the information storage medium; and

reading clip audio-video (AV) streams corresponding to the read clip information from the information storage medium, at least two of the read clip AV streams correspond to the motion picture data for different angles, and each of the at least two clip AV streams comprising a plurality of interleaved blocks, and the interleaved blocks included in one clip AV stream among the at least two clip AV streams are interleaved with the interleaved blocks included in the other clip AV streams among the at least two clip AV streams,

wherein;

each read clip information comprises an entry point map comprising;

information on entry points of a corresponding one of the read clip audio-video streams for random access, and

information on whether each of the entry points is an angle change point, and

the angle change point is a point through which the motion picture is reproduced from one of the angles to another of the angles,

the clip information further comprises information on an address of the entry point map, and

a start point of the interleaved blocks is the angle change point.

7. The method of claim 6, wherein the information on the entry points comprises location information of the entry points among the AV streams.

8. The method of claim 6, wherein the information storage medium further comprises playlist information which comprises at least one playitem corresponding to the read clip AV streams.

9. The method of claim 8, wherein the at least one playitem comprises angle block information, and the angle block information comprises information on whether the playitem is for the motion picture data of the different angles.

10. The method of claim 9, wherein the angle block information further comprises information on a number of the different angles of the motion picture data of the different angles.
