The transform type is determined to be a Discrete Cosine Transform or Discrete Sine Transform, the size of the current block is equal to or greater than 4×4, and the transform type is determined independently to a direction of the intra prediction mode of the current block."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Encoding method and decoding method, and device implementing the same","description":"An encoding method obtains an intra prediction mode related to a current block from a bitstream; obtains prediction samples of the current block by performing intra prediction on the current block bas","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11997263","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.
