Video analyzer

A content receiver, comprising:

• a communication system configured to receive video content comprising a plurality of video frames from a content source;
• and
• a video analyzer communicatively coupled to the communication system the video analyzer comprising a processor and memory, the video analyzer configured to:
• determine, for each of a plurality of blocks of video, that one or more blocks of video content may be perceived as blocky based upon a luminance of the respective block;
• determine, when one or more blocks of video content may be perceived as blocky, when the one or more blocks of video content have edges distinct from centers of the respective one or more blocks of video content;
• determine, for each video block determined to have edges distinct from centers of the respective one or more blocks of video content, a weight for each edge of the respective video block;
• determine, for each video block determined to have edge a weight over a predestined threshold, that the respective video block is blocky when there is no pattern between the respective video block and at least one other adjacent video block;
• determine that compression of the video content is causing blockiness in the one or more blocks of video content by determining when a total number of blocks of video in the one or more of the plurality of video frames determined to be blocky, while excluding the respective adjacent video blocks having the pattern there-between, exceeds a predetermined threshold;
• and
• trigger at least one content receiver response when the compression of the video content is causing blockiness in the one or more blocks of video which have edge distinctness.
