摘要/Abstract

摘要： 在详细分析高效率视频编码标准HEVC现有码率控制算法JCTVC-H0213的基础上，提出了一种快速有效的改进算法。该算法根据前一帧的目标比特和实际比特的比值来确定当前帧量化参数。在恒定比特率情况下将该算法与JCTVC-H0213进行比较，实验结果表明该算法对于大部分内容特性序列峰值信噪比变化值提高2.4dB以上，达到了很好的码率控制效果；并且该算法非常简单，适用于实时的码率控制应用。

Abstract: By analyzing the current rate control algorithm, i.e., JCTVC-H0213 for high efficiency video coding, a new fast and effective method to derive the quantization parameter was proposed, relying on the ratio of the targeted bitrate to the actual coding bitrate of the previous frame. The proposed algorithm was implemented on the HM6.3 platform in the constant bit rate case. The experimental results show that the proposed algorithm outperforms JCTVC-H0213 rate control algorithm. A performance gain in variety of Peak Signal-to-Noise Ratio (PSNR) of more than 2.4 dB can be observed. In conclusion, the proposed algorithm achieves outstanding rate distortion performance with a low complexity, which makes it well suited to real-time scenarios.

Key words: high efficiency video coding, rate control, targeted bitrate, real-time application, HM6.3
