The household encryption key can be configured to be used by the client device to encrypt recordings of media content it makes and/or decrypt recordings of media content it previously made or that it receives from another client device that encrypted the recording using the household key. If the subscriber identifier has previously been associated with a household encryption key, the update server retrieves the household key and sends it to the client device. If the subscriber identifier has not previously been associated with a household encryption key, the update server retrieves a new household key from a pool, associates the new household key with the subscriber identifier, and sends it to the client device."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method of provisioning persistent household keys for in-home media content distribution","description":"A method of providing a household key to a client device, comprising receiving a key request including a subscriber identifier at an update server from a client device, and determining whether the sub","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9847975","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.
