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."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Quality metric for compressed video","description":"Methods and systems are disclosed for calculating and applying a VQ metric which operates during the decoding of compressed video.
