  • Patent number: 10182233
    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.
    Type: Grant

  • Publication number: 20110222837
    Abstract: In one embodiment, a system, comprising an encoder comprising memory with personal video recording assist (PVRA) logic; and a processor configured to execute the PVRA logic to: provide a reference picture reordering command (RPRC) in association with one or more pictures of a video stream to be received in a video stream receive-and-process (VSRP) device, the RPRC configured to cause the VSRP device to reorder or modify associations of reference pictures to ascending reference indices of a derived, default reference picture list such that lower tier number pictures precede higher tier number pictures in a modified reference picture list used for decoding the one or more pictures.
