Abstract

Rate-Distortion Optimized Quantization (RDOQ) brings significant improvement of coding performance in High Efficiency Video Coding (HEVC). However, it results in high computational complexity to determine the best quantization levels for each transform coefficient when applying rate and distortion optimization operation. In this paper, we firstly proposed an efficient way to skip the all zero coding units. Then we further propose a fast RDOQ scheme by skipping the optimization step of All Quantized Zero Blocks except DC Coefficient (AQZB-DC). Moreover, a rate difference model is established to select optimal quantization level for AQZB-DC blocks. Experiments are carried out on reference software HM 16.0 and the results show that the proposed method achieves 42.00% and 39.63% quantization time saving under Random Access (RA) and Low Delay (LD) configuration on average, while the BD-Rate loss is only 0.03% and 0.06%, respectively.
