Claim Text:
1. A method for encoding a video signal having a plurality of frames, comprising: transforming coefficients in a plurality of blocks of a current frame of the plurality of frames to generate transform coefficients; quantizing the transform coefficients to generate quantized transform coefficients, the quantized transform coefficients including zero value quantized coefficients and non-zero value quantized coefficients; ordering the quantized transform coefficients in each of the plurality of blocks according to a scan order; identifying, for each block of the plurality of blocks, a value for an entropy-related characteristic associated with the block, the value including at least one of a position of a last non-zero value quantized coefficient of the quantized transform coefficients arranged in the scan order or a number of non-zero value quantized coefficients among the quantized transform coefficients of the block; assigning, to each of a plurality of segments for the frame, a unique, assigned value corresponding to the entropy-related characteristic; assigning at least some of the plurality of blocks to a segment of the plurality of segments based on a comparison of the value for the entropy-related characteristic associated with the block and the unique, assigned value for the segment; and encoding the at least some of the plurality of blocks assigned to the segment of the plurality of segments without encoding an end of block indictor for each block of the at least some of the plurality of blocks.
