There is also provided a method of improving latency in a Rate Distortion Optimization apparatus, where the Rate Distortion Optimization apparatus assesses nine intra prediction modes and the method further comprises re-ordering processing of intra prediction modes such that a first six modes processed are not dependent on a block of pixels above and to the right of a current block of pixels, and processing the re-ordered sequence of intra prediction modes in the Rate Distortion Optimization apparatus."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Latency rate distortion optimisation","description":"There is provided a method of improving latency in a Rate Distortion Optimization apparatus, comprising re-ordering processing of a sequence of 4×4 blocks of pixels received for processing by the Rate","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8488673","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.
