The multiple encrypted versions comprising at least a low resolution version and a high resolution version, and each encrypted version is divided into encrypted blocks, containing multiple encrypted images. The method includes selecting an encrypted block from the low resolution encrypted version of the encrypted video stream, selecting a subset of the encrypted block containing an image to be extracted; transmitting to the terminal the subset; decrypting of the subset by the terminal; and extracting the image, from the decrypted subset."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Extraction of video streams","description":"A method for the selective extraction, by a terminal, of at least one image to be extracted, from an encrypted video stream where multiple encrypted versions are stored on a server incapable of decryp","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-10477264","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.
