TWO PASS QUANTIZATION FOR CABAC CODERS

摘要

This disclosure describes techniques for quantizing coefficients of a video block for a video coding process that supports context-based adaptive binary arithmetic coding (CABAC). A method may comprise estimating a last non-zero coeffi-cient of the video block, and generating a set of quantized coefficients for the video block based on an assumption that the esti-mated last non-zero coefficient is actually the last non-zero coefficient of the video block.
