Fast bypass mode for CABAC

In this paper, improved bypass mode for CABAC called pass through mode is proposed. The bypass mode stands for a special coding process in CABAC to be used for encoding a symbol having equal probability. The proposed scheme realizes complexity reduction of the bypass mode in decoder without any loss of compression performance. We implemented the proposed scheme into test model software that is used for HEVC standardization process to evaluate its performance. Our experimental result shows that the run-time of the bypass mode process in decoder is reduced by about 60 %.
