Abstract

A remote control method and system embody a graphic user interface. The present invention includes a remote controller having a touch pad and a digital television having a GUI. That is, a viewer can select a menu displayed on the digital television by using the touch pad. It is thus possible to overcome control limitations of the remote controller, namely complexity of the rapidly-developed functions of the television. In addition, the viewer can watch menus displayed on the screen of the digital television, operate the touch pad and execute a wanted control operation. As a result, the viewer can easily conveniently control the digital television through simple operations of the remote controller.

Claims

1. A remote control method including a GUI function, comprising the steps of:

transmitting, at a remote control means, a touch pad signal mode set up by a button key operation of a viewer to an image display means;

displaying, at the image display means, menu selection information in a GUI environment according to the touch pad signal mode;

transmitting, at the remote control means, a touch control signal generated by a touch pad contact of the viewer to the image display means; and

executing, at the image display means, the displayed menu selection information according to the touch control signal.

2. The method according to claim 1, further comprising a step of distinguishing, at the image display means, the touch pad signal mode and button signal mode received from the remote control means, and supplying them to a corresponding control unit.

3. The method according to claim 1, wherein the menu selection information comprises a main manual for allowing the viewer to select a menu and a pointer for designating the menu selected by the viewer.

4. The method according to claim 1, wherein the touch control signal is a movement position signal having movement distance/direction information of the pointer generated when the viewer moves by a predetermined distance in a state where he/she maintains a first contact position to the touch pad.

5. The method according to claim 1, wherein the touch control signal is a menu selection signal generated when the viewer maintains a first contact position to the touch pad over a predetermined time, or when he/she continuously contacts the first position to the touch pad.

6. The method according to claim 1, wherein the menu selection information is displayed in a window type.

7. A remote control system including a GUI function, comprising:

a remote control means having a button processing unit for generating a button signal in response to a button key press of a viewer, a touch pad control unit for generating a touch control signal in response to a touch pad contact of the viewer; and

a signal transmitting unit for remotely transmitting the signals from the button processing unit or touch pad control unit; and

an image display means having a signal receiving unit for receiving the signals from the signal transmitting unit;

a signal control unit for receiving the signals from the signal receiving unit and distinguishing modes of each signal;

an image control unit for executing the operation according to a button signal included in the button signal mode, when the mode distinguished by the signal control unit is a button signal mode; and

a GUI control unit for displaying a main manual and a pointer on the screen in a GUI environment, and controlling the pointer according to a touch pad operation of the viewer, when the mode distinguished by the signal control unit is a touch pad signal mode, wherein the pointer is moved corresponding to be moved from a reference position of the touch pad.

8. The system according to claim 7, wherein the GUI control unit performs the control operation to recognize characters which the viewer inputs to the touch pad and to search information corresponding to the characters.

9. The system according to claim 7, wherein the remote control means varies the previously-set button signal mode into the touch pad signal mode and enables the touch pad control unit, when the viewer selects a menu button key among the button keys.

10. The system according to claim 7, wherein, when the viewer continuously contacts the touch pad, one of a few menus of the main manual is executed by the pointer.

11. A remote controller for remotely controlling a digital television, comprising:

a button unit having a plurality of button keys including a menu button key for activating a touch pad at its one side;

the touch pad installed at the other side of the button unit, and contacted by a viewer for executing menu selection information displayed on the digital television;

a button key control unit for varying a previously-set button signal mode into a touch pad signal mode according to a menu button key operation of the viewer;

a touch pad control unit for generating a touch control signal including a movement position signal and a menu selection signal according to a touch pad contact of the viewer, and

a signal transmitting unit for remotely transmitting the touch pad signal mode from the button key control unit or the touch control signal from the touch pad control unit to the digital television.

12. The remote controller according to claim 11, wherein the menu selection information comprises a main manual for allowing the viewer to select a menu and a pointer for designating the menu selected by the viewer.

13. The remote controller according to claim 11, wherein, when the viewer moves by a predetermined distance in a state where he/she maintains a first contact position to the touch pad, the touch pad control unit calculates movement distance and direction information on the basis of the first contact position and final contact position.

14. The remote controller according to claim 11, wherein the touch pad control unit senses whether the viewer maintains a first contact position to the touch pad over a predetermined time, or continuously contacts the first contact position to the touch pad, and generates a menu selection signal.
