Variances between blocks of a current video frame and blocks of a previous video frame are used to partition the current video frame into varying block sizes depending upon the magnitude of the variances. Blocks with low variance may be combined with other low variance blocks to form larger blocks, while blocks with high variance may be further partitioned into smaller blocks to improve coding efficiency. In cases where partitioning is unlikely to provide improved efficiency, the variation calculations may be skipped in favor of using fixed partitioning for a frame. The partitioned frames are decoded."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Video coding using adaptive source variance based partitioning","description":"Frames including in a video bitstream may be partitioned using source difference variance based partitioning before encoding.
