ABSTRACT:
The invention provides a mobile communication terminal in which the operating time can be prolonged when the videophone function is used, and a videophone with many persons involved therein can be realized while maintaining the freedom of the movement. A TRX unit receives video and audio data sent from a base station. A radio processing LSI performs the A/D conversion of the video and audio data. A CPU extracts the received video and audio data from a compressed state by use of MPEG or the like, and then outputs the resulting data to a built-in LCD and a built-in loudspeaker. When the data output destination is changed to a Bluetooth control LSI by manipulating operation keys, the built-in LCD and built-in loudspeaker are turned off. By using a Bluetooth TRX unit, the Bluetooth control LSI sends the compressed data through a Bluetooth receiver to an external display and loudspeaker.
