    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: In one method embodiment, for each of a number the plural blocks to be matched, displaying whether an indication of closeness in match between the each of the plural blocks exceeds a first threshold; displaying a counter value which is incremented each time the first threshold is exceeded for closeness of the block matching of a particular block; displaying an indicator of whether the counter value exceeds a second threshold, the exceeding of the second threshold indicating that a defined quantity of blocks has exceeded the first threshold; and responsive to determining that the counter value exceeds the second threshold, displaying that a scene change detection has been triggered.
