The estimate of the actual intra prediction mode can be determined by selecting one of the first most probable mode and the second most probable mode as the estimate of the actual intra prediction in response to both the first most probable mode and the second most probable mode being different angular prediction modes. The estimate of the actual intra prediction mode plus difference information can be used to identify the actual intra prediction mode used to code the current video block."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Reference mode selection in intra mode coding","description":"A video coder can determine a first most probable intra prediction mode and a second most probable intra prediction mode for a current video block, and based on the first and second most probable intr","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9628789","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.
