Claim:
1. An information reproduction system comprising a first information reproduction device and a second information reproduction device that can communicate with each other, wherein: the first information reproduction device includes: a first network connection unit to make connection to the Internet; a first player unit to reproduce a main content which is a reproduction target file recorded on a portable information recording medium and an additional content which is a network file acquired via the Internet; an access analyzer to extract a network file entry as Internet connection destination information contained in an Internet connection request issued by executing a content application recorded on the portable information recording medium, when the portable information recording medium is reproduced in the first player unit; a network-file entry storage unit to store the network file entry extracted by the access analyzer; a first transmission-reception unit to transmit information through the first network connection unit; and a first central controller to cause the first transmission-reception unit to transmit the network file entry stored in the network-file entry storage unit, when a network-file entry transmission request is received; the second information reproduction device includes: a second network connection unit to make connection to the Internet without use of the first network connection unit; a second player unit to reproduce a main content which is a reproduction target file recorded on the portable information recording medium, and an additional content which is a network file acquired via the Internet; a second transmission-reception unit to transmit and receive information through the second network connection unit; a network-file table storage unit to store the network file entry as a network file table; a second central controller to control a process of causing the second transmission-reception unit to transmit the network-file entry transmission request to the first information reproduction device, the second central controller performing a process of updating the network file table in the network-file table storage unit by using the network file entry transmitted from the first information reproduction device; a network-file storage unit to store a network file; and a network-file prior acquisition unit to acquire the network file via the Internet through the second network connection unit, on a basis of the network file entry stored as the network file table and cause the network-file storage unit to store the acquired network file, the network file being acquired through the second network connection unit directly from the Internet without being routed through the first information reproduction device; and if it is determined that a network file entry included in an Internet connection request based on a content application recorded on the portable information recording medium exists in the network file table when the portable information recording medium is reproduced in the second player unit, the second central controller reads a network file identified by the network file entry which is determined to exist in the network file table, from the network-file storage unit, and supplies the network file to the second player unit.
