Abstract

A method and apparatus for encoding a frame of audio/video data, segment by segment, comprising a number of pixels each having a plurality of pixel color components by creating a frame group table in which each pixel entry includes a dominant pixel color component of the plurality of pixel color components, and determining a set of segment reference pixels for each encoded segment, wherein each one of the segment reference pixels is a pixel within each one of the encoded segments having a most intense dominant pixel color value.

Claims

1. A method, comprising:

encoding a frame of audio/video data, segment by segment, comprising a number of pixels each having a plurality of pixel color components by;

creating a frame group table of encoded pixel values in which each pixel entry includes a dominant pixel color component of the plurality of pixel color components; and

determining a set of segment reference pixels for each encoded segment, wherein each one of the segment reference pixels is a pixel within each one of the encoded segments having a most intense dominant pixel color value.

2. The method of claim 1, wherein each pixel entry further includes at least one pixel parameter value.

3. The method of claim 2, wherein the pixel parameter values include at least one of luminance, chrominance, and color depth information.

4. The method of claim 2, including scaling down each pixel parameter value prior to storing each pixel entry into the frame group table.

5. The method of claim 1, wherein prior to encoding the frame of audio/video data, creating a frame group file to store a header, the frame group table, and each set of segment reference pixels.

6. The method of claim 5, wherein after creating the frame group table, writing a pointer to a next frame group to the frame group file.

7. The method of claim 5, including storing audio data within the frame group file.

8. The method of claim 1, including encoding audio data into the frame group table.

9. The method of claim 1, including encoding audio synchronization tags into the frame group table.

10. The method of claim 1, wherein determining the set of segment reference pixels includes comparing, on a pixel by pixel basis for each segment, a current pixel color value with a previously stored dominant pixel color value and storing the plurality of pixel color components and pixel parameters of the pixel with the most intense dominant pixel color component.

11. The method of claim 1, wherein each pixel entry further comprises scaled down non-dominant pixel color components.

12. The method of claim 1, wherein the plurality of pixel color components comprises at least one of the sets of primary color components, red, green, and blue, or cyan, magenta, and yellow.

13. The method of claim 12, wherein the dominant pixel color components include red, green, blue, and black.

14. The method of claim 13, wherein the dominant pixel color component black is determined by comparing an average of the red, green, and blue pixel component values to a black threshold value.

15. The method of claim 1, wherein an encoded segment is a row of pixels within the frame of audio/video data.

16. The method of claim 1, wherein creating a frame group table further comprises scaling down the dominant pixel color component.

17. The method of claim 1, wherein the frame group table includes pixel entries for a plurality of frames.

18. The method of claim 1, wherein redundant encoded pixel values of the frame group table share common table entries.

19. The method of claim 18, wherein redundant encoded pixel values share identical dominant pixel color components and identical pixel parameter values.

20. The method of claim 18, wherein redundant encoded pixel values share dominant pixel color components and pixel parameters values that are similar to one another within a tolerance range.

21. An encoder, comprising:

the encoder to create, pixel by pixel, a frame table of encoded segments of audio/video data, wherein each pixel is represented by a single pixel color component; and

the encoder to create a set of color scaling pixels for each encoded segment, wherein each color scaling pixel is selected based upon a pixel having a most significant color intensity value with respect to similarly colored pixels within the segment.

22. The encoder of claim 21, wherein the frame table data of encoded segments of audio/video data for each pixel includes pixel parameter values for at least one of, luminance, chrominance, and color depth.

23. The encoder of claim 22, wherein the pixel parameter values are scaled down values.

24. A machine readable medium storing a set of instructions that, when executed by a machine, cause the machine to execute a method, the method comprising:

encoding a frame of audio/video data, segment by segment, comprising a number of pixels each having a plurality of pixel color components by;

creating a frame group table in which each pixel entry comprises a dominant pixel color component of the plurality of pixel color components; and

determining a set of segment reference pixels for each encoded segment, wherein each one of the segment reference pixels is a pixel within each one of the encoded segments having a most intense dominant pixel color value.
