The image decoding apparatus disclosed herein executes decoding and filtering in raster scan order across a screen independently of the sizes and positional relations of tiles. At a tile boundary, decoding proceeds to a right adjacent tile on the same row, rather than decoding coding blocks on one row down in the same tile, and filtering is also executed using decoded data of row-wise adjacent coding blocks."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Image decoding apparatus executing successive tile decoding and filtering around tile boundary","description":"For a decoding apparatus based on H.265/HEVC with single-core or single-threaded hardware not parallelized, which executes decoding a plurality of tiles and filtering around a tile boundary, the discl","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9800874","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.
