Information reproduction system, information reproduction method, information reproduction device, and access analysis device

Abstract

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 application are provided. 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.
