Abstract
A system and method receives video data and its corresponding alpha channel data using a single stream or file, each of the video data and alpha channel data in the same format, and decompresses each set of data using a single decompression algorithm.
Claims18
A method of providing video data and alpha channel data, comprising:
- decompressing, using a decompression algorithm, data from a stream into a first set of data having a format;
- decompressing, using the decompression algorithm, data from the stream into a second set of data having the format;
- extracting the alpha channel data from a portion of the second set of data;
- extracting the video data from the first set of data;
- providing the video data and alpha channel data;
- converting the set of video data and alpha channel data from the format to a second format;
- and
- wherein the video data and alpha channel data is provided in the second format.
A computer program product comprising a non-transitory computer useable medium having computer readable program code embodied therein for providing video data and alpha channel data, the computer program product comprising computer readable program code devices configured to cause a computer system to:
- decompress, using a decompression algorithm, data from a stream into a first set of data having a format;
- decompress, using the decompression algorithm, data from the stream into a second set of data having the format;
- extract the alpha channel data from a portion of the second set of data;
- extract the video data from the first set of data;
- provide the video data and alpha channel data computer readable program code devices configured to cause the computer system to convert the set of video data and alpha channel data from the format to a second format;
- and
- wherein the video data and alpha channel data is provided in the second format.
A system comprising:
- a processor;
- and
- a storage device storing instructions operable to cause the processor to perform operations comprising:
- decompressing, using a decompression algorithm, data from a stream into a first set of data having a format;
- decompressing, using the decompression algorithm, data from the stream into a second set of data having the format;
- extracting the alpha channel data from a portion of the second set of data;
- extracting the video data from the first set of data;
- providing the video data and alpha channel data converting the set of video data and alpha channel data from the format to a second format;
- and
- wherein the video data and alpha channel data is provided in the second format.
