6 is a flowchart illustrating an example of a method of operating an image display device according to an exemplary embodiment of the present invention, and FIGS. 7 to 16 are views referenced to explain the operation method of FIG. 6.

First, referring to FIG. 6, the image display device 100 receives an image through the image receiving unit 105. Then, the received image is signal-processed, and the signal-processed image is displayed on the display 180.

For example, the image display device 100 receives a broadcast signal received through an antenna through a tuner unit 110, etc., and processes the signal by the control unit 170 to display the signal-processed broadcast image on the display 180 Can be marked on. In particular, by processing one broadcast signal, one broadcast image may be displayed on the display 180.

Next, the image display apparatus 100 determines whether there are a plurality of divided image display inputs based on a single source (S605), and if applicable, displays a plurality of divided images (S610).

For example, when there is an external input image display input from the set-top box through the user input interface unit 150, the control unit 170 may receive an external input image through the external device interface unit 130. have.

In this case, when there is a plurality of divided image display inputs for displaying a plurality of divided images among external input images, the controller 170 may receive a plurality of divided images through the external device interface unit 130.

For example, through the set-top box 50, a plurality of divided images may be received. Specifically, a content provider that provides a broadcast image through the set-top box 50 may transmit a plurality of divided images as one stream in order to increase the convenience of use during user viewing when there is a divided image display input. have.

In addition, the image display device 100 may receive one stream including a plurality of divided images through the external device interface unit 130.

The control unit 170 in the image display device 100 demultiplexes the received stream, extracts a plurality of divided images from the demultiplexed signal, and performs signal processing on each divided image, As this single screen, it can be controlled to be displayed on the display 180. Accordingly, the user can view a plurality of divided images at the same time, thereby increasing user convenience.

Meanwhile, the image display device 100 displays an indicator for selecting or focusing any one of a plurality of divided images (S615).

For example, the controller 170 generates an indicator for selecting or focusing any one of the plurality of divided images when there is an operation such as a menu key of the remote control device 200 while a plurality of divided images are displayed, and , It is possible to control to display an indicator generated on any one of a plurality of divided images on the display 180.

For example, when four divided images are displayed on the display 180, an indicator for thickening the border of the image may be displayed on one of them.

Meanwhile, the image display apparatus 100 determines whether there is an indicator movement input (S625), and if applicable, moves the indicator to display (S625).

The controller 170 may control the indicator to be moved and displayed according to a movement input for the indicator. For example, when there is an input of moving a direction key from the remote control device 200, the indicator may be moved in the corresponding direction. Specifically, according to the left key movement input, the indicator may be moved to be positioned on the left divided image.

On the other hand, the control unit 170 may control a pointer that is displayed to be moved in response to the movement of the remote control device to be displayed as shown in FIG. 4.
