Abstract

The present invention relates to a method of generating contents information for managing contents including stereo-scopic contents being two-dimensional contents and three dimensional contents, and an apparatus for managing contents, the method including the steps of, when there is a scene change of contents, adding a second field including information on each of a plurality of scenes corresponding to a plurality of types, respectively, to the contents information.

Claims

1. A method of generating contents information comprising:

adding a first field representing the number of scene changes of contents to contents information; and

adding a second field including information on each of a plurality of scenes corresponding to a plurality of types to the contents information, respectively, when there is the scene change of contents.

2. The method of claim 1, wherein the second field includes information on a start frame of each of the plurality of scenes, and information on the plurality of types each corresponding to the plurality of scenes.

3. The method of claim 2, wherein the second field further includes a plurality of header information required for decoding each of the plurality of scenes and corresponding to each of the plurality of scenes.

4. The method of claim 1, further comprising adding a third field including information on a camera photographing the contents to contents information.

5. The method of claim 4, wherein the third field includes:

information on the type of arrangement of a plurality of cameras photographing the contents;

information on a baseline that is a distance between the plurality of cameras;

information on a focal length that is a distance between lenses of the plurality of cameras and an image plane; and

information on a distance between the baseline and a convergence point.

6. The method of claim 1, further comprising adding a fourth field including information on a disparity between the contents of the plurality of scenes and the contents information.

7. The method of claim 6, wherein the fourth field includes:

information on a magnitude of the Max disparity between the contents of the plurality of scenes; and

information on a magnitude of the Min disparity between the contents of the plurality of scenes

8. A method of generating contents information comprising:

adding a first field representing the number of scene changes of contents to contents information; and

adding a second field including information on the types of contents to the contents information, when there is no scene change of contents.

9. The method of claim 8, further comprising adding a third field including information on a camera photographing the contents.

10. The method of claim 9, wherein the third field includes:

information on the type of arrangement of a plurality of cameras photographing the contents;

information on a baseline that is a distance between the plurality of cameras;

information on a focal length that is a distance between lenses of the plurality of cameras and an image plane; and

information on a convergence point that is a distance between the baseline and a convergence point.

11. An apparatus for managing contents comprising:

a control signal generating unit generating a binary format for a scene descriptor,

an object descriptor, and a stereoscopic descriptor;

an encoding unit encoding media data and control signals input from the control signal generating unit and outputting an encoding stream (elementary stream, ES); and

a unit generating a file after receiving the encoding stream, wherein

the stereoscopic descriptor includes information required for decoding and reproducing the contents composed of two-dimensional contents and three-dimensional contents, or various types of three-dimensional contents.

12. The apparatus of claim 11, further comprising a packetizing unit extracting the media data and the control signals included in the file and generating packets.

13. The apparatus of claim 11, wherein the stereoscopic descriptor includes a scene change specification information field on each of a plurality of scenes corresponding to a plurality of types, respectively.

14. The apparatus of claim 13, wherein the scene change specification information field includes:

a plurality of start frame index parameters representing each start access unit (AU) of the plurality of scenes;

a plurality of contents format parameters representing each content type of the plurality of scenes; and

a plurality of decoder specification information parameters including header information required for decoding each contents of the plurality of scenes.

15. The apparatus of claim 13, wherein the stereoscopic descriptor further includes a stereoscopic camera information field including information on a stereoscopic camera.

16. The apparatus of claim 15, wherein the stereoscopic camera information field includes:

a stereoscopic camera setting parameter representing an arrangement form of a plurality of cameras photographing three-dimensional contents;

a baseline parameter representing a baseline that is a distance between the plurality of cameras;

a focal length parameter representing a distance between lenses of the plurality of cameras and an image plane; and

a convergence point distance representing a distance between the baseline and a convergence point.

17. The apparatus of claim 13, wherein the stereoscopic descriptor further includes a stereoscopic contents information field including information on a disparity between contents of the plurality of scenes.

18. The apparatus of claim 17, wherein the stereoscopic contents information field includes:

a Max disparity parameter representing a magnitude of a Max disparity between contents of the plurality of scenes; and

a Min disparity parameter representing a magnitude of a Min disparity between contents of the plurality of scenes.

19. The apparatus of claim 11, further comprising a three-dimensional contents generating unit converting sizes and colors of contents into three-dimensional contents.
