Abstract: Methods and systems are disclosed for calculating and applying a VQ metric which operates during the decoding of compressed video. As such, this metric is appropriate for all formats of compressed video codecs (e.g., MPEG-2, AVC and HEVC). The VQ metric relies on the decoded quantization parameter (Qp) together with analysis of both the compressed and decoded video. As such, the VQ metric does not require a reference video, and is less cumbersome to use for multiple channels, e.g., statistically multiplexed channels.

Abstract translation: 公开了用于计算和应用在压缩视频解码期间操作的VQ度量的方法和系统。 因此，该度量适用于所有格式的压缩视频编解码器（例如，MPEG-2，AVC和HEVC）.VQ度量依赖于解码的量化参数（Qp）以及压缩和解码的视频的分析。 因此，VQ度量不需要参考视频，并且对于多个频道使用不太麻烦，例如， 统计复用通道。
