The LCD screen data of the mobile terminal may be display data processed by the mobile terminal 40 in response to the data input through the key input unit 42 of the mobile terminal 40, and also, a key of the mobile terminal 40. As described above, the display data may be service related display data provided through the portable terminal 40 without an input through the input unit 42.

In the embodiment according to the invention, in the signal processing method of the apparatus further comprising an external key input means 10, the user is any of the key input section 42 or the external key input means 10 of the portable terminal 40. It is possible to implement one selectively, which will be apparent to those skilled in the art.

Accordingly, the user can use the useful service provided by the portable terminal 40 through the convenient key input means 10 such as a remote controller and a joystick, and a display means 20 having excellent visual effect and readability such as a TV.

As mentioned above, preferred embodiments of the present invention are disclosed for the purpose of illustration, and those skilled in the art can improve and change various other embodiments within the spirit and technical scope of the present invention disclosed in the appended claims below. , Replacement or addition would be possible.

As described above, the portable terminal user interface device according to the present invention, when the user uses a useful service provided through the portable terminal, is more convenient than the key pad embedded in the portable terminal itself and the built in the portable terminal itself. There is an effect that can utilize the output means that the visual effect is better than the LCD.

In addition, by providing an additional external expansion device and a portable terminal user interface device that the portable terminal can exchange data with each other, there is an effect of using the location information of the portable terminal and storing a large amount of data collected through the portable terminal. .
