提出了一种对诸如MPEG - 2、H.263、MPEG - 4以及视频编码标准草案H.264/AVC（高级视频编码）等视频编码标准的编码器控制的统一方法。通过峰值信噪比（PSNR）和主观测试结果对各种标准的性能进行了比较。结果表明，符合H.264/AVC标准的编码器通常能达到与符合先前标准的编码器基本相同的重现质量，而所需比特率通常为后者的60%或更低。
A unified approach to the coder control of video coding standards such as MPEG-2, H.263, MPEG-4, and the draft video coding standard H.264/AVC (advanced video coding) is presented. The performance of the various standards is compared by means of PSNR and subjective testing results. The results indicate that H.264/AVC compliant encoders typically achieve essentially the same reproduction quality as encoders that are compliant with the previous standards while typically requiring 60% or less of the bit rate.
