INFORMATION PROVIDING SYSTEM, COMMUNICATION TERMINAL, AND MANAGEMENT DEVICE

摘要

PROBLEM TO BE SOLVED: To prevent temporal concentration of access in a mechanism of accessing a device storing content data by using information superposed on voice. ! SOLUTION: A broadcast station 20 superposes an acquisition ID to acquire content data on a broadcast wave. A communication terminal 10 extracts the acquisition ID from voice produced by a television set 30, and obtains time information, address information, and an ID for prior distribution corresponding to the acquisition ID from a management device 50. The communication terminal 10 obtains and stores content data on the basis of the address information when time indicated by the time information comes. The broadcast station 20 broadcasts an output ID of the content data by superposing it on a broadcast wave at timing to output the content data. When the communication terminal 10 extracts the output ID from voice produced by the television set 30, it outputs content data stored in association with the ID for prior distribution including the
