Multimedia Signal Control Device and Control Method Thereof

A multimedia signal control device, for connecting and controlling a portable data-processing device and a multimedia playback device, the multimedia signal control device comprising:

• a signal-connecting unit connected to the portable data-processing device, converting a multimedia signal in a first signal format outputted by the portable data-processing device into a multimedia signal in a second signal format recognizable and processible to the multimedia playback device, and transmitting the converted multimedia signal to the multimedia playback device;
• and
• a remote control unit connected to the signal-connecting unit, transmitting a control signal to the signal-connecting unit so that the signal-connecting unit transmits the control signal to the portable data-processing device,
• wherein, the portable data-processing device outputs, in response to the control signal, the multimedia signal in the first signal format to the signal-connecting unit, and the signal-connecting unit converts the multimedia signal in the first signal format into the multimedia signal in the second signal format and then transmits the converted multimedia signal to the multimedia playback device.

A method for controlling a multimedia signal, the method comprising the following steps:

• establishing a signal-transmitting connection between a portable data-processing device and a multimedia playback device by using a signal-connecting unit;
• receiving a control signal from a remote control unit by using the signal-connecting unit;
• transmitting the received control signal to the portable data-processing device or the multimedia playback device by using the signal-connecting unit;
• and
• manipulating the portable data-processing device or the multimedia playback device according to the received control signal.
