摘要

本文主要通过峰值信噪比、率失真曲线、平均比特率节约等主观测试，对几种视频编码标准进行性能比较。对H.265/高效视频编码(HEVC)、H.264/MPEG4-高级视频编码(AVC)、MPEG4V2、MPEG4和谷歌视频编解码器VP8、VP9等不同码率和峰值信噪比(PSNR)下的视频编码标准进行了具体的计算。与早期的视频编码标准相比，比特率平均降低了约50%。结果表明，H.265/HEVC在低比特率下实现了峰值信噪比。与较低版本的视频编码标准相比，这类似于高编码效率。

Analysis of video coding standards using PSNR and bit rate saving

This paper mainly deals with the performance comparison of several video coding standards by means of peak signal-to-noise ratio and subjective testing like Rate Distortion (RD) curves and average bit-rate savings. A particular procedure is applied for the video coding standards H.265/High Efficiency Video Coding (HEVC), H.264/MPEG4- Advance Video Coding (AVC), MPEG4V2, MPEG4 and the Google video codec's such as VP8, VP9 at different bit-rates and Peak Signal-to-Noise Ratios (PSNR) are estimated. The bit-rate reduction on an average is achieved about 50% for comparable to earlier video coding standards. The results obtained illustrate the H.265/HEVC achieving high peak signal-to-noise at low bit rates. This resembles high coding efficiency, comparing with lower versions of video coding standards.
