通过峰值信噪比（PSNR）和主观测试结果比较了几代视频编码标准的压缩性能。一个统一的方法被应用于分析设计，包括H。262/MPEG-2视频，H. 263，MPEG-4 Visual，H. 264/MPEG-4高级视频编码（AVC）和高效视频编码（HEVC）。针对WVGA和HD序列的主观测试结果表明，HEVC编码器可以实现与符合H. 264/MPEG-4 AVC时，平均使用约50%的比特率。HEVC设计被证明对于低比特率、高分辨率视频内容和低延迟通信应用特别有效。所测量的主观改善稍微超过由PSNR度量测量的改善。
The compression capability of several generations of video coding standards is compared by means of peak signal-to-noise ratio (PSNR) and subjective testing results. A unified approach is applied to the analysis of designs, including H. 262/MPEG-2 Video, H. 263, MPEG-4 Visual, H. 264/MPEG-4 Advanced Video Coding (AVC), and High Efficiency Video Coding (HEVC). The results of subjective tests for WVGA and HD sequences indicate that HEVC encoders can achieve equivalent subjective reproduction quality as encoders that conform to H. 264/MPEG-4 AVC when using approximately 50% less bit rate on average. The HEVC design is shown to be especially effective for low bit rates, high-resolution video content, and low-delay communication applications. The measured subjective improvement somewhat exceeds the improvement measured by the PSNR metric.
