The tweeter page transmitted from the TV 100 is displayed on the display module of the remote controller 200. The controller 270 of the remote controller 200 analyzes the received information and performs mode switching. For example, when the received content is text, the controller 270 switches from the control mode to the editing mode.

Accordingly, when a user watches TV and there is a marker indicating a poll and a feed and a mark indicating a social network hash tag on the TV screen, the user selects the markers and confirms the real time feed related to the image currently displayed on the screen You can enter comments and comments about the survey.

6 is a second embodiment of contents linkage between a video display device and an external input device according to an embodiment of the present invention.

Referring to FIG. 6, when a user presses a capture button provided on the remote controller 200, a capture signal is transmitted to the TV 100. The control unit 150 of the TV 100 captures an image currently displayed on the screen according to the capture signal and transmits the captured screen shot to the remote controller 200. [

Accordingly, the user can capture (screen) the screen shot displayed on the display module 144 of the remote controller 200 by touching and manipulating (enlarging / reducing) the captured image on the TV 100. The edited image is stored in the storage unit 260.

7 is a third embodiment of contents linkage between a video display device and an external input device according to an embodiment of the present invention.

The third embodiment shown in FIG. 7 is an example in which the QR code 80 is selected using the remote controller 200 on the screen of the TV 100. When the QR code 80 is selected, the controller 270 of the remote controller 200 can decode the QR code 80 and display the corresponding information.

When the UI capable of inputting text is displayed on the screen of the TV 100, it is practically difficult for the user to input the text accurately to the remote controller 200 while watching the UI.

Accordingly, the present invention provides a method of easily and conveniently inputting a text by displaying a corresponding UI on a remote controller 200 when a TV UI for inputting text is displayed on a screen of the TV 100.

FIG. 8 is a fourth embodiment of contents linkage between a video display device and an external input device according to an embodiment of the present invention.

As shown in FIG. 8, when a pop-up 90 for inputting text is displayed on the screen of the TV 100, the user selects the pop-up 90 using the remote controller 200. When the pop-up 90 is selected, the controller 150 of the TV 100 transmits a pop-up 90 that allows text input to the remote controller 200, and the controller 270 of the remote controller 200 controls the pop- And displays the transmitted pop-up 90 on the display module 244 by switching to the edit mode. At this time, the control unit 270 divides the screen and displays the keyboard together with the pop-up 90. [

Accordingly, the user inputs text while simultaneously watching the pop-up 90 and the keyboard in the remote controller 200, and the input text is automatically input to the screen of the TV 100. [ When the text input is completed, the control unit 270 returns to the control mode. Such an embodiment can be applied to text input and text conversion as well as text input.

FIG. 9 is a fifth embodiment of contents linkage between a video display device and an external input device according to an embodiment of the present invention.

The present invention can display and control an image selected by the user through the remote controller 200 when two or more different images are displayed on the screen of the TV 100 as divided screens. 9, when the user selects the second image from the first and second images through the remote controller 200, the controller 150 of the V 100 displays the first image as a full screen And transmits the selected second image to the remote controller 200.

The user can control the channel and volume of the second image displayed on the screen through the remote controller 200 and can listen to the voice of the second image by connecting the earphone to the earphone terminal of the remote controller 200. [

Accordingly, the user can enjoy different images through the video display device and the remote controller 200, for example, images that are more important than the voice, such as the first image, and are important to the voice, such as the second image. When the second image through the remote controller 200 is stopped or terminated, the controller 15 of the TV 100 automatically displays the first and second images.

As described above, according to the present invention, the image or additional information selected in the image display device is displayed on the external input device through the content linkage between the image display device and the external input device to perform image viewing or text input, It is possible to overcome the limitation of inputting and editing information and to use the video and additional information displayed on the video display device more conveniently and variously.

According to an embodiment of the present invention, the above-described method can be implemented as a computer-readable code on a medium on which a program is recorded. The computer readable medium includes all kinds of recording devices in which data that can be read by a computer system is stored. Examples of the computer-readable medium include ROM, RAM, CD-ROM, magnetic tape, floppy disk, optical data storage, and the like, and also implemented in the form of a carrier wave (for example, transmission over the Internet) . Further, the computer may include a control unit of the terminal.

The image display apparatus and the control method thereof using the fingerprint recognition as described above are not limited to the configuration and method of the embodiments described above, Or some of them may be selectively combined.
