A user relief management unit monitors failure information notifying, grasps a delivery disabled period from the failure information, specifies a delivery destination user for a content of which the view period is overlapped with the delivery disabled period and issues a relief right with a relief period specified thereto to the specified user. A contract period processing unit manages the relief right and permits viewing within the relief period set by the relief right when a view right based on the relief right is output from the user terminal device."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Content delivery apparatus, user terminal device, relief management method and computer program","description":"A content delivery apparatus, when a content delivery request is outputted from a user terminal device, encrypts the requested content with an encryption key, adds a view period to it to deliver it to","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9792755","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.
