In the system including video reproduction devices, the vehicle-mounted video reproduction device transmits an NF entry transmission request, stores a received NF entry as an NF table, acquires in advance an NF on the basis of a stored NF entry and stores it, and if it is determined that an NF entry corresponding to a reproduction target file exists in the NF table when an optical disc is reproduced in a player unit, executes a proxy response for reading an NF identified by the NF entry corresponding to the reproduction target file from an NF storage unit and for supplying it to the player unit."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Information reproduction system, information reproduction method, information reproduction device, and access analysis device","description":"A system, a method, and a device that can reproduce a reproduction target file recorded on a portable information recording medium and a network file acquired in response to a request of a content app","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9736421","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.
