The method further includes decoding, for one of the units, a current block from the plurality of blocks using an entry from a history motion vector (HMVP) buffer. The method further includes updating the HMVP buffer with a motion vector of the decoded current block. The method further includes determining whether the current block is at a beginning of a row included in the grid of the one of the units. The method further includes, in response to determining that the current block is the beginning of the row, resetting the HMVP buffer."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and apparatus for history-based motion vector prediction","description":"A method of video decoding for a decoder includes acquiring a current picture from a coded video bitstream, where the current picture is segmented into a plurality of units with each unit divided into","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-10491902","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.
