Efficient content compression and decompression system and method
A content compression/compression system and method are disclosed in which a pre-processing step is performed before any compression and a post-processing step is performed once a compressed piece of content is decompressed.
1. A method for compressing a piece of video content, the method comprising:
suppressing one or more least significant raw data portions in a piece of video content to generate a pre-processed piece of video content; and
compressing the pre-processed piece of video content using discrete cosine transform based video compression that reduces the amount of data.
2. The method of claim 1 , wherein each least significant data portion further comprises a bit-plane.
3. The method of claim 2 , wherein suppressing one or more least significant raw data portions further comprises removing the one or more least significant bit-planes.
4. The method of claim 2 , wherein suppressing one or more least significant raw data portions further comprises setting a plurality of bits in the one or more least significant bit-planes to a single value that is one of “1” and “0”.
5. The method of claim 1 , wherein the discrete cosine transform based video compression is one of motion JPEG, motion JPEG 2000, H.263, MPEG-4 and H.264.
6. A method for decompressing a compressed piece of video content, the method comprising:
decompressing a compressed piece of video content using discrete cosine transform based video compression to generate a decompressed piece of content wherein the compressed piece of video content had been pre-processed to suppress one or more least significant unconverted data portions; and
regenerating the suppressed one or more least significant data portions.
7. The method of claim 6 , wherein the one or more least significant data portions further comprises one or more bit-planes.
8. The method of claim 7 , wherein regenerating the suppressed one or more least significant data portions further comprises inserting a number of least significant bit-planes into the decompressed piece of video content based on the number of least significant bit-planes removed from an original piece of video content that was compressed.
9. The method of claim 8 , wherein the inserting a number of least significant bit-planes further comprises distributing a plurality of bits in each least significant bit-plane.
10. The method of claim 9 , wherein distributing the plurality of bits further comprises one of inserting “0” bits into the least significant bit-plane, inserting “1” bits into the least significant bit-plane and inserting random bit into the least significant bit-plane.
11. The method of claim 6 , wherein the discrete cosine transform based video compression is one of motion JPEG, motion JPEG 2000, H.263, MPEG-4 and H.264.
