It is desired to improve handling of key selection vectors of revocation lists. A structured key selection vector for a revocation list is provided. The key selection vector is structured to contain at least one bit field with a predetermined number of bits and at a predetermined location in the key selection vector. The bit field contains information relating to a group property of a device, which group property allows to process as a group a plurality of key selection vectors storing the same or similar group property information in said at least one bit field."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Key selection vector, mobile device and method for processing the key selection vector, digital content output device, and revocation list","description":"A key selection vector for a revocation list in an HDCP system as well as a mobile device and a method for processing a key selection vector, a digital content output device using a key selection vect","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8542837","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.
