Abstract

A system and method are provided for compressing data. In use, luminescence data of a frame is updated at a first predetermined rate, while chrominance data of the frame is updated at a second predetermined rate that is less than the first predetermined rate. Moreover, pause information may be inserted with the compressed data, where the pause information may be used when the video data is paused during the playback thereof to increase the quality of a still frame.

Claims (10)

1. A method for compressing video data comprising:

updating luminescence data of a frame at a first predetermined rate; and

updating chrominance data of the frame at a second predetermined rate that is less than the first predetermined rate;

wherein one or more frequency bands of the chrominance data is omitted utilizing a wavelet filter.

2. The method as recited in claim 1 , and further comprising interpolating omitted portions of the chrominance data upon decompression of the video data.

3. A computer program product embodied on a computer readable medium for compressing video data, comprising:

computer code for updating luminescence data of a frame at a first predetermined rate; and

computer code for updating chrominance data of the frame at a second predetermined rate that is less than the first predetermined rate;

wherein one or more frequency bands of the chrominance data is omitted utilizing a wavelet filter.

4. The computer program product as recited in claim 3 , and further comprising interpolating omitted portions of the chrominance data upon decompression of the video data.
