Accordingly, embodiments of the present disclosure not require a reference video, which makes it more easily computable and therefore more easily deployable for multiple channels, such as statistically multiplexed channels. In some embodiments, SVQ logic may be integrated in encodersuch as integrated in an applications specific integrated circuit ASIC. SVQ logic may be configured to provide a video quality metric for video encoded by encoder Each of these standards includes certain attributes of the compression process: Frame Types, Transform Blocks, e. The advantage of this diagram is that it describes a systematic way to describe color mathematically. Headend may comprise an encoder having video compression functionality. The reason for this is that edges are important features to the human visual system, while dark areas of scenes are the opposite. The object passes or reflects some colors and absorbs others, deriving the observed by the eye color from the fractions that have not been absorbed. Presently described embodiments of SQV are no-reference. Generally, non-reference frames may be more highly compressed than reference frames.

    The associated reference P-frame may have a WQA of 6. B-frames are bi-predicted, meaning they are encoded differentially to two neighboring I or P reference frames, so B-frames require several other reference frames i.

    Instead, the proper scope of the disclosure is defined by the appended claims.

    The method of claim 1, further comprising: converting the weighted sum to the frame adjusted Qp by dividing the weighted sum of all adjusted Qp values by a sum of all applied weighting values. The local interface may have additional elements, which are omitted for simplicity, such as controllers, buffers cachesdrivers, repeaters, and receivers, to enable communications. A WQA may also be calculated for non-reference frames such as B-frames.

Furthermore, although embodiments of the present disclosure have been described as being associated with data stored in memory and other storage mediums, data can also be stored on or read from other types of computer-readable media, such as secondary storage devices, like hard disks, floppy disks, or a CD-ROM, a carrier wave from the Internet, or other forms of RAM or ROM.

    In some embodiments, storage device may be externally coupled to a content server not shown. Encoder may further comprise SVQ logic configured to receive encoded video e. Similarly, at stepuncompressed domain processing may be performed on the first video stream to store a second set of macroblock classifications.

    Presently described embodiments of SQV are no-reference. There exists a need to be able to monitor and measure the video quality of compressed video. The processing includes frame statistics collection during decoding compressed domain processingand the generation of certain frame statistics after the frame has been decoded pixel domain processing.
