  • METHOD AND APPARATUS FOR TEMPORAL WAVELET COMPRESSION
    Publication number: 20090323819
    Abstract: A system is described that comprises a method and apparatus for further compressing an already compressed data stream, using a mathematical comparison computation. The method comprises: receiving a data stream that has been compressed using a first compression protocol; decompressing the data stream using the first compression protocol; reducing temporal redundancy in the data stream using a comparison protocol; and recompressing the data stream using the first compression protocol. The apparatus comprises: a decompression unit to receive and decompress a compressed data stream to produce decompressed data; a comparison unit, coupled to the decompression unit, to perform a mathematical comparison operation on the decompressed data to produce resultant data; and a recompression unit to compress the resultant data to produce a further compressed data stream.

  • Method and apparatus for temporal wavelet compression
    Patent number: 7558322
    Abstract: A system is described that comprises a method and apparatus for further compressing an already compressed data stream, using a mathematical exclusive-OR computation. The method comprises: receiving a data stream that has been compressed using a first compression protocol; decompressing the data stream using the first compression protocol; reducing temporal redundancy in the data stream using an exclusive-OR comparison protocol; and recompressing the data stream using the first compression protocol. The apparatus comprises: a decompression unit to receive and decompress a compressed data stream to produce decompressed data; an exclusive-OR comparison unit, coupled to the decompression unit, to perform a mathematical exclusive-OR operation on the decompressed data to produce resultant data; and a recompression unit to compress the resultant data to produce a further compressed data stream.
