In addition, a control signal receiving unit 360 for receiving the control signal transmitted from the above-described remote control unit is included, the motion signal from the remote control unit can be output via a wire or wireless signal such as RF signal have.

In addition, a memory unit 380 for storing the EPG information received through the tuner 310 is included, and stored in the memory unit 380 when an EPG display command is input through the control signal receiving unit 360. And a controller 390 for displaying EPG information on the display 350.

The controller 390 causes the EPG information to be displayed on the screen, and generates a pointer on the EPG screen with respect to the motion signal received through the control signal receiver 360 to perform a motion corresponding to the motion. do.

This operation will be described in detail using the EPG screen illustrated in FIG. 4.

FIG. 4 is a diagram illustrating EPG information displayed on the display unit 350. In the EPG screen 400, broadcast programs for each channel / time band are listed with the time being the horizontal axis and the channel being the vertical axis.

When a user inputs a specific key of a remote control unit or takes a specific motion, a pointer 401 is generated in the center of the EPG screen 400, and the control unit 390 of the display device receives the control signal receiver 360. When a predetermined command is input through the control unit, the image signal processor 340 or the OSD generator 370 is controlled to generate a pointer 401 in the center of the EPG screen.

The pointer 401 is a tool for allowing a user to recognize the tracking result of the motion of the remote control unit, and can be regarded as similar to that of a mouse. However, in the exemplary embodiment of the present invention, the pointer 401 may be displayed on the screen when there is a specific function key input or a specific motion input after the EPG screen is displayed by the user.

According to the motion of the remote control unit by the user, the pointer 401 is moved on the EPG screen, and the user places the pointer 401 on a specific broadcast program and then inputs a specific function key to broadcast the corresponding broadcast. You can set watching or scheduled watching or scheduled recording for the program.

In addition, when the EPG display command is received, the controller 390 of the display apparatus further forms key helpers 402, 403, 404, and 405 for page switching together with the EPG screen 400.

When the pointer 401 is positioned on the key helpers by a user's motion, the controller 390 controls to switch pages in the corresponding direction. That is, the upper key helper 402 and the lower key helper 403 for switching the page for the broadcast program for each channel on the EPG screen are displayed, and the right key helper for switching the page for the broadcast program for each time zone on the EPG screen. 405 and left key helper 404 are displayed.

When the pointer 401 is positioned on the right key helper 405 according to the motion tracking of the remote control unit, the control unit 390 displays broadcast program information of a next time zone for the displayed broadcast channels. . On the other hand, if the user places the pointer 401 on the right key helper 405 and then inputs a specific function key, it may be possible to switch pages.

In addition, when the pointer 401 is positioned on the upper key helper 402, the controller 390 displays broadcast program information of other channels broadcasted in the displayed time zone. Again, when the user moves the pointer 401 and inputs a specific function key, broadcast program information for previous channels may be displayed.

Meanwhile, although the EPG screen 400 illustrated in FIG. 4 forms a separate tag called a key helper for page switching by broadcasting time zone and page switching by channel, an edge border of the EPG screen 400 is illustrated. In the case where the pointer 401 is crossed, a configuration for switching to the corresponding page is also possible.

That is, when a separate key helper tag is not configured, the pointer 401 is placed on the right edge rim line 406 of the EPG screen 400 or the border 406 is placed on the pointer 401. If is passed, the screen may be switched to the right page (broadcast program page of the next time zone). The switching of the channel page (page moving up or down) can also be performed by this configuration.

In particular, when acceleration information is included in the motion signal transmitted from the remote control unit, a configuration in which a plurality of page switching is performed may be an embodiment. That is, the controller 390 of the display apparatus reads out a signal input through the control signal receiver 360 to determine whether motion acceleration information is included, and if an acceleration value of more than a preset value is input, Allows page switching in the motion direction to be performed multiple times.

For example, when the user moves the remote control unit to the right by more than a certain acceleration, the control unit 390 of the display device receiving such a signal controls the broadcast time zone to be displayed after 2 hours or 3 hours for the displayed channels. can do. However, this technical configuration will be limited to the case that the remote control unit is provided with an acceleration sensor for measuring the motion acceleration.

On the other hand, according to an embodiment of the present invention will be described with reference to Figure 5 that the page switching is performed by the broadcast program information of the EPG screen by the sliding method according to the motion of the remote control unit.

FIG. 5 is a diagram for illustrating how page switching of EPG information is performed according to an embodiment of the present invention.

First, when the user inputs the EPG information confirmation key of the remote control unit, the EPG information stored in the memory unit is displayed on the display unit 350 of the display device.

Then, when a motion of the remote control unit or a predetermined pointer generation key input is generated, a pointer is generated on the screen of the display unit, and when the user moves the pointer to input a right key helper, as shown in FIG. 5. Page transition is performed.

The controller 390 of the display apparatus moves the broadcast program for the currently displayed channels to the left and controls the broadcast program information for the next time slot for the corresponding channels to gradually move from the right to the left.

By this process, the currently displayed broadcast program information gradually disappears while moving to the left side, and the broadcast program information of the next time zone is gradually displayed from the right side and displayed on the entire EPG screen.

In the EPG screen, the next page is gradually displayed on the screen by sliding the page-by-time page or the page-by-channel page, so that the user can obtain a visual effect.

FIG. 6 is a diagram for describing a method of performing channel selection using a pointer in an EPG screen.

Referring to FIG. 6, when selecting a channel or selecting an external input or an image file through the split screen 600, the display apparatus moves the pointer 601 or selects a channel using motion information of the remote control unit. Can be done.

When the user selects the multi-division mode of the display device, a pointer 601 for tracking the motion of the remote control unit is displayed, and the movement from one object to another is performed by the pointer 601.

In addition, when the user inputs the selection key (confirmation key) of the remote control unit to the specific object (channel) on which the pointer 601 is placed, the channel can be viewed in full screen.

As described above, the page switching can be performed through the motion of the remote control unit for the multi-screen shown in FIG. 6, and the user divides the pointer 601 to one side of the multi-screen in the corresponding direction. The page of the screen to be switched can be switched.
