Claim:
1. An information-providing system comprising: a sound output device adapted to output, as a sound wave, identifying information which is modulated into a sound signal; an identifying-information resolution server connected to an information-communication network, and adapted to identify address information for accessing a content server which is connected to the information-communication network, based on the identifying information, and send the address information; and a portable terminal device that includes a sound receiving section adapted to receive the sound wave outputted from the sound output device, a demodulating section adapted to demodulate the identifying information from the received sound wave, a resolution section adapted to send the demodulated identifying information to the identifying-information resolution server and receive the address information from the identifying-information resolution server, and an access section adapted to access the content server using the address information acquired, wherein the address information includes a URL for accessing the content server, the identifying information does not include the address information, the identifying-information resolution server identifies the address information by associating the address information with the identifying information, and the identifying-information resolution server includes an association section that associates identifying information with address information including a URL for each of a plurality of time of day ranges, in which a first URL is associated with first identifying information in a first time of day range and a second URL is associated with the first identifying information in a second time of day range that is different from the first time of day range, wherein the portable terminal device further includes a position acquiring section adapted to acquire position information which indicates a position of the portable terminal device, the identifying-information resolution server is configured to identify the address information based on the identifying information and the position information sent from the portable terminal device, and the resolution section of the portable terminal device sends the identifying information demodulated by the demodulation section and the position information acquired by the position acquiring section to the identifying-information resolution server to acquire the address information.
