Abstract
A video compression method and system including object-oriented compression plus error correction using decoder feedback.
Claims17
An error correcting decoder, comprising:
- (a) a first decoder;
- (b) a deinterleaver coupled to the output of said first decoder;
- (c) a second decoder coupled to the output of said deinterleaver;
- (d) a memory coupled to said first decoder;
- and
- (e) a feedback coupled to said second decoder and said memory and output to said deinterleaver;
- (f) wherein said feedback errors corrected in a codeword by said second decoder to correct errors of related codewords in said memory and thereby correcting errors in said deinterleaver for codewords for said second decoder.
4 more elements
A method of motion-compensated video coding, comprising the steps of:
- (a) provide motion data and texture data for a plurality of groups of pixels;
- (b) aggregating the motion data of said groups of pixels;
- (c) aggregating the texture data of said groups of pixels;
- (d) inserting a resynchronization word between said aggregated motion data and said aggregated texture data.
1 more element
A method of motion-compensated video decoding, comprising the steps of:
- (a) interpreting a first sequence of symbols as aggregated motion data of groups of pixels;
- and
- (b) interpreting a second sequence of symbols as aggregated texture data of said groups of pixels wherein said first sequence and said sequence are separated by a resynchronization word.
