After PCM coding, deblocking filtering may be applied. The deblocking filter may be selected for the present PCM coded block based on its noise and/or the noise of its adjacent block. The noise of the PCM coded block is indicated by a so-called PCM quantization parameter, which is also encoded in the bitstream."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Quantization parameter for blocks coded in the PCM mode","description":"The present invention relates to coding of an image of a video sequence block wisely and, in particular, to coding of a block of samples, which may be chrominace or luminance samples, or samples of an","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9774851","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.
