In reducing MV data redundancy, the value of MVx and/or MVy can have a baseline at the width (W), or height (H) of the respective block, whereby fewer bits need to be encoded. One embodiment for enhancing RExt provides an improved selection of a default block vector predictor for the first CU performing intra-block copying in a CTU."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Intra-block copying enhancements for HEVC in-range-extension (RExt)","description":"High efficiency video coding (HEVC) enhancements are described for intra-block copying for reducing motion vector (MV) coding redundancy and enhancing in range extensions (RExt) by selecting a default","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9774879","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.
