Abstract:
The complexity of coding a significant_coeff_flag in video coding such as High Efficiency Video Coding (HEVC) is able to be reduced using the same mapping to select luma and chroma contexts for the coding of 4×4 significant maps. As a result, a 15 element lookup table and multiple branches are able to be removed to select the context index, and WD text is also simplified.
