The method includes determining whether the current block is encoded in a non-angular intra prediction mode. The method includes, in response to the block being encoded in the non-angular intra prediction mode, determining whether the reference line index indicates a non-zero reference line from the plurality of reference lines. The method includes in response to determining that the reference line index is the non-zero reference line, (i) enabling non-angular intra prediction modes for the non-zero reference line, and (ii) decoding the current block with at least one reference sample from the non-zero reference line."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and apparatus for improved planar and DC modes for non-zero reference lines","description":"A method of video decoding includes retrieving, from a coded video bitstream for a current block encoded in an intra prediction mode, a reference line index indicating a reference line from a pluralit","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11496748","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.
