Abstract

Provided are a method for transmitting data related to a stereoscopic image and a method for playing back a stereoscopic image. The stereoscopic image data transmitting method includes generating stereoscopic image data related to a stereoscopic still image in a predetermined file format (200), and transmitting the generated data. The file format (200) includes a media information unit (220) including the stereoscopic still image (222), control information (212) for controlling playing back the stereoscopic still image, and image composition information (214) indicating a type of composing a stereoscopic image using the stereoscopic still image.

Claims

1. A method of transmitting stereoscopic image data, comprising:

generating stereoscopic image data related to a stereoscopic still image in a predetermined file format; and

transmitting the generated data,

wherein the file format includes a media information unit including the stereoscopic still image, control information for controlling playing back the stereoscopic still image, and image composition information indicating a type of composing a stereoscopic image using the stereoscopic still image.

2. The method of claim 1, wherein the file format includes image type information that indicates a type of providing the stereoscopic image or a file type.

3. The method of claim 1, wherein the control information includes the image composition information.

4. The method of claim 1, wherein the media information unit includes a plurality of stereoscopic still images that compose one scene of the stereoscopic image, and the image composition information indicates a type of composing the stereoscopic image based on the plurality of stereoscopic still images.

5. The method of claim 1, wherein the control information includes identification information about the control information, and the header information unit includes a list of the identification information.

6. The method of claim 1, wherein when the stereoscopic image includes a main image and a supplementary image, the control information includes reference information that indicates whether the stereoscopic still image is the main image or the supplementary image.

7. The method of claim 1, wherein the header information unit includes time information about a playback start time and a playback end time of the stereoscopic still image.

8. The method of claim 1, wherein the header information unit includes information about a method of displaying the stereoscopic still image in three dimensions.

9. A method of playing back a stereoscopic image, comprising:

receiving data generated in a file format including a media information unit having a stereoscopic still image and image composition information and control information;

composing a stereoscopic image from the stereoscopic still image according to the image composition information; and

playing back the stereoscopic image according to the control information.

10. The method of claim 9, further comprising:

checking image type information indicating a type of providing the stereoscopic image or a type of a file.

11. The method of claim 9, wherein the image composition information is included in the control information.

12. The method of claim 9, wherein the image composition information is information about a plurality of stereoscopic still images that compose one scene of the stereoscopic image.

13. The method of claim 9, further comprising:

determining whether the image composition information is included or not.

14. The method of claim 9, further comprising:

inquiring identification information of the control information in an identification information list included in the header information unit.

15. The method of claim 9, wherein said composing a stereoscopic image from the stereoscopic still image includes determining reference information that indicates whether the stereoscopic still image is the main image or the supplementary image.

16. The method of claim 9, wherein said playing back the stereoscopic image includes checking time information about a reproduction start time and a reproduction end time of the stereoscopic still image.

17. The method of claim 9, wherein said playing back the stereoscopic image includes checking information about a method of displaying the stereoscopic still image in three dimensions.

18. The method of claim 9, wherein said composing a stereoscopic image from the stereoscopic still image includes linking a 2D video or an audio with the stereoscopic still image.

19. A method of generating a file of stereoscopic image data, comprising:

generating a media information unit including a stereoscopic still image;

generating a header information unit including control information for controlling the stereoscopic still image and image composition information for indicating a type of composing a stereoscopic image using the stereoscopic still image; and

generating a file format including the media information unit and the header information unit.

20. The method of claim 19, wherein the file format includes image type information that indicates a type of file or a type of providing the stereoscopic image.
