Abstract
Provided are a method and apparatus for processing a graphic stream. The method may include determining whether a graphic picture is reproducible as a three-dimensional (3D) image by assigning different depth values according to graphic objects or by assigning the same depth value to the graphic picture, using 3D capability information.
Claims48
A method of processing a graphic stream, the method comprising:
- generating graphic objects by decoding the graphic stream;
- generating two-dimensional (2D) composition information and color information by decoding the graphic stream;
- generating three-dimensional (3D) composition information from the 2D composition information using metadata about the graphic stream;
- and
- outputting the graphic objects to a screen using the 3D composition information to and the color information.
An apparatus for processing a graphic stream, the apparatus comprising:
- a graphic processor configured to generate graphic objects, two-dimensional (2D) composition information, and color information by decoding a graphic stream;
- a depth processor configured to generate three-dimensional (3D) composition information from the 2D composition information using metadata about the graphic stream;
- and
- is a graphic picture output unit configured to output the graphic objects to a screen using the 3D composition information and the color information.
A computer-readable storage medium comprising:
- a graphic stream;
- and
- metadata about the graphic stream,
- wherein the graphic stream comprises a graphic object, two-dimensional (2D) composition information, and color information, and
- the metadata comprises hole compensation information and one of graphic object identification information, a depth value of the graphic object, and a location to movement value, and the metadata is used to generate three-dimensional (3D) composition information for outputting the graphic object in 3D from the 2D composition information.
A computer-readable storage medium having stored therein program is instructions to cause a processor to implement a method of processing a graphic stream, the method comprising:
- generating graphic objects by decoding a graphic stream;
- generating two-dimensional (2D) composition information and color information by decoding the graphic stream;
- generating three-dimensional (3D) composition information from the 2D composition information using metadata about the graphic stream;
- and
- outputting the graphic objects to a screen using the 3D composition information and the color information.
A computer-readable storage medium having stored therein program instructions to cause a processor to implement a method of processing a graphic stream, the method comprising:
- determining whether a graphic picture is reproducible in three dimensions (3D) by assigning different depth values according to graphic objects or by assigning a same depth value to the graphic picture, using 3D capability information.
A computer-readable storage medium comprising:
- a graphic stream;
- and
- metadata about the graphic stream for reproducing the graphic stream in a three-dimensional (3D) graphic picture,
- wherein the metadata comprises depth information about a graphic object and depth information about a graphic picture, and
- the depth information about the graphic object comprises hole compensation information and one of a graphic object identifier, a depth value of the graphic object, and a location movement value.
A method of processing a graphic stream, the method comprising determining whether a graphic picture is reproducible in three dimensions (3D) by assigning different depth values according to graphic objects, or by assigning the same depth value to the graphic picture, using 3D capability information.
An apparatus for processing a graphic stream comprising a graphic decoder configured to determine whether a graphic picture is reproducible in three-dimensions (3D) by assigning different depth values according to graphic objects, or assigning the same depth value to the graphic picture, using 3D capability information.
