Data broadcast data, which is broadcast in data broadcasts, is constructed by disposing, for example, EMD (Electric Music Distribution) links required to acquire song data as actual broadcast data, which is broadcast in actual broadcasts by a transmitting device, the actual broadcast data is transmitted, and the data broadcast data wherein the EMD links for the song data in the actual broadcasts are disposed, is transmitted periodically during the transmission of the actual broadcast data. The actual broadcast data and the data broadcast data are received by a user terminal, and the EMD links disposed in the data broadcast data are stored whenever there is an input of an operation to attach a 'bookmark'. Thus, audio data such as songs in programs broadcast can easily be acquired by radio.
