A handsfree video phone system that includes a video phone terminal 106 and a car device in which a microphone 101, a speaker 102, a camera 103 are connected with an instrument panel 105 via a cable 104. The video phone terminal 106 is connected with the instrument panel 105 via a wireless communication medium 107. When the video phone terminal 106 is brought into the vehicle, the instrument panel 105 informs the video phone terminal 106 of the attribute information on the system structure. According to the attribute information, the video phone terminal 106 switches the paths of multiplexed audio-video data so as to replace a microphone, a speaker, a camera, and a display that have been built in the video phone terminal 106 with the microphone 101, the speaker 102, the camera 103, and a display of the instrument panel 105 when the status changes to the communication status.
