[ What is claimed is:] [1.] 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 secon

[ What is claimed is:] [1.] 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. [2.] 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. [10.] 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. The method of claim 10, wherein:(a) each of said group of pixels are the pixels of a 16 by 16 macroblock of pixels of a frame. The method of claim 10, wherein:(a) each of said group of pixels are the pixels of a 16 by 16 macroblock of pixels of a frame and lying within an object within said frame. The method of claim 10, wherein:(a) each of said group of pixels are the pixels of an 8 by 8 block of pixels of a frame. The method of claim 10, wherein:(a) each of said group of pixels are the pixels of an 8 by 8 block of pixels of a frame and lying within an object within said frame. The method of claim 10 wherein:(a) said motion data is encoded with variable length code. The method of claim 10, wherein:(a) said texture data is encoded with variable length code. The method of claim 10 further comprising the step of:(a) interpreting a third sequence of symbols as shape data for an object which includes said groups of pixels, wherein a second resynchronization word separates said shape data from said aggregated motion data and said aggregated texture data.
