Abstract

Disclosed is a multimedia system using a mobile communication terminal and an external connection device for the same. The multimedia system uses a video/audio output device, a peripheral device, and an external connection device. The multimedia system includes a mobile communication terminal having a video/audio output function and a peripheral device control function so that the mobile communication terminal outputs images and sounds by using the video/audio output device and controls the peripheral device; and an external connection device for connecting the mobile communication terminal to the video/audio output device and the peripheral device, relaying the images and sounds from the mobile communication terminal to the video/audio output device, and relaying data transmitted/received between the mobile communication terminal and the peripheral device. When multimedia data is reproduced by using a mobile communication terminal, it is easily connected to an external video/audio output device (e.g. a TV) or a peripheral device (e.g. a computer, a mouse, a joystick) to construct a multimedia system.

Claims
