To provide an information providing system capable of facilitating the acquisition of information by displaying information related to a broadcast in a portable terminal device to be used by a user with the use of acoustic identification information.
A broadcast reproduction apparatus emits broadcast sound with identification information superimposed thereon. An identification information resolution server includes an identification information/address information correspondence table for storing the address information of contents for each time period so as to retrieve the table by using time information when the identification information is received from a portable terminal device, and returns the address information of the corresponding content. The portable terminal device includes: a sound collection part for collecting the broadcast sound emitted by the broadcast reproduction apparatus; a demodulation part for demodulating the identification information from the collected broadcast sound; an operation part for receiving an operation by a user; an identification information resolution part for transmitting the identification information to the identification information resolution server when the operation part is operated and acquiring the address information; and a content access part for accessing to the content by using the acquired address information.
