The method also includes deriving the modified position (x′, y′) using arithmetic shift operations; setting the second motion vector equal to a motion vector at the modified position (x′, y′) of the pixel in the previous frame; and deriving the motion vector of the current block using a motion vector predictor and a difference motion vector."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Buffer compression for motion vector competition","description":"Deriving a motion vector of a current block, in a current frame, including: generating a motion vector predictor candidate list including a set of first motion vectors and a second motion vector, wher","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9749657","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
