A predictive quantization parameter deriving unit derives a predictive quantization parameter of the second block using quantization parameters of a third block adjacent to the left of the second block and a fourth block adjacent to the top of the second block. A differential quantization parameter generation unit generates a differential quantization parameter of the second block from a difference between the quantization parameter of the second block and the predictive quantization parameter. A first bitstream generation unit codes the differential quantization parameter of the second block."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Moving picture coding device, moving picture coding method, and moving picture coding program, and moving picture decoding device, moving picture decoding method, and moving picture decoding program","description":"In a moving picture coding device that codes moving pictures in units of a block by partitioning a first block, which is obtained by partitioning each picture of the moving pictures into predetermined","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9667989","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.
