The method comprises determining whether or not an error is present in an input image data stream; determining a similarity between patterns of transform coefficients that are generated in the course of decoding the input image data stream; and detecting the starting position of the error based on the similarity determination. Accordingly, a decoder can independently detect the position of the error accurately, and the quality of an image which is replaced and restored using error concealment can be improved."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method of and apparatus for detecting error in image data stream","description":"A method is provided for detecting an error in an image data stream in a device environment where digital image data is reproduced, especially, in a wired/wireless network such as a personal portable ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8478056","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.
