A contents reproducing apparatus includes a main CPU, and the main CPU causes a DSP to decode broadcast data included in a radio packet signal input via a LAN controller in a radio mode, and inputs decoded PCM data to a D/A converter. As a result, a sound of Internet radio is output from a speaker. On the other hand, in a telephone mode, the main CPU causes the DSP to decode receiving speech data included in a telephone packet signal input via the LAN controller, and inputs decoded PCM data to a PCM codec. The CPU causes the DSP to encode the sending speech data input from the PCM codec, and packetizes encoded data to input it to the LAN controller. Thus, it is possible to make a communication with an opponent party.
