Abstract

A display apparatus includes a display which displays an image; an external peripheral device; a peripheral device interface connected to the external peripheral device; an image composing module which combines a video signal with a graphic signal and outputs a combined signal to the display; and a controller which outputs a graphic signal to the image composing module when the graphic signal is input from the external peripheral device through the peripheral device interface, the graphic signal being associated with contents of a video signal displayed on the display and displayed along with the video signal.

Claims

1. A display apparatus comprising:

a display configured to display an image;

a peripheral device interface configured to connect to an external peripheral device;

an image composing module configured to combine a video signal with a graphic signal and output a combined signal to the display;

a video processor configured to process a video signal; and

a controller configured to directly output the graphic signal input from the external peripheral device to the image composing module in response to the graphic signal being input from the external peripheral device through the peripheral device interface, and to output the video signal input from the external peripheral device to the video processor in response to the video signal being input from the external peripheral device through the peripheral device interface.

2. The display apparatus of claim 1, further comprising a user interface configured to receive a selection by a user, wherein the controller is further configured to output a control signal to the external peripheral device so that the graphic signal provided from the external peripheral device is output to the image composing module in response to a selection signal to display the desired graphic signal being received through the user interface.

3. The display apparatus of claim 1, wherein the graphic signal provided from the external peripheral device comprises transparency information.

4. The display apparatus of claim 1, wherein the peripheral device interface comprises a USB port and an HDMI port.

5. The display apparatus of claim 1, wherein the external peripheral device is connectable to a network and receives data through the network.

6. The display apparatus of claim 1, wherein the peripheral device interface is further configured to receive the video signal and the graphic signal as separate signals.

7. The display apparatus of claim 1, wherein the peripheral device interface is further configured to receive the video signal and the graphic signal in different signal forms.

8. A display apparatus comprising:

a display configured to display an image;

a peripheral device interface configured to connect to an external peripheral device, wherein the external peripheral device is configured to output a video signal and a graphic signal to the peripheral device interface;

a video processor configured to process a video signal;

an image composing module configured to combine the video signal with a graphic signal associated with contents of the video signal and displayed together with the video signal, and output a combined signal to the display; and

a controller configured to determine whether an image signal received through the peripheral device interface is the graphic signal, directly output the graphic signal to the image composing module in response to the image signal being the graphic signal, and output the video signal to the video processor in response to the image signal being the video signal.

9. An image displaying method of a display apparatus comprising a peripheral device interface connected to an external peripheral device and a display, the image displaying method comprising:

receiving a graphic signal and/or a video signal from the peripheral device through the peripheral device interface;

directly outputting the graphic signal received from the peripheral device to the image composing module in response to the graphic signal being input from the external peripheral device through the peripheral device interface and outputting the video signal received from the peripheral device to the video processor in response to the video signal being input from the external peripheral device through the peripheral device interface;

combining the graphic signal with the video signal; and

displaying the video signal and the graphic signal on the display.

10. The image displaying method of claim 9, wherein the display apparatus further comprises a user interface which receives a selection by a user, and

the method further comprises:

receiving a selection signal to display the desired graphic signal through the user interface; and

outputting a control signal to the external peripheral device so that the graphic signal provided from the external peripheral device is output to an image composing module.

11. The image displaying method of claim 9, wherein the graphic signal is a separate signal from the video signal.

12. The image displaying method of claim 9, wherein the graphic signal is in a signal form different from the video signal.

13. An image displaying method of a display apparatus comprising a peripheral device interface connected to an external peripheral device and a display, the image displaying method comprising:

receiving an image signal through the peripheral device interface from the peripheral device;

determining whether the image signal is a graphic signal or a video signal received from the peripheral device through the peripheral device interface;

directly outputting the graphic signal to the image composing module in response to the image signal being the graphic signal, and outputting the video signal to the video processor in response to the image signal being the video signal; and

combining an input graphic signal with the video signal in response to the image signal being the graphic signal or processing a video signal in response to the image signal is the video signal, and displaying the signal on the display.

14. An image display system, comprising:

an external peripheral device configured to output a desired signal and a video signal;

a peripheral device interface configured to receive the desired signal and the video signal output by the external peripheral device;

a video processor configured to process the video signal;

an image composing module configured to combine the video signal with the desired signal and output a combined signal;

a display configured to display the combined signal;

a user interface configured to input a user selection signal for selecting the desired signal; and

a controller configured to directly output the graphic signal input from the external peripheral device to the image composing module in response to the graphic signal being input from the external peripheral device through the peripheral device interface, and to output the video signal input from the external peripheral device to the video processor in response to the video signal being input from the external peripheral device through the peripheral device interface.

15. The image display system of claim 14, wherein in response to a selection signal from the user interface being received, the controller is further configured to output a control signal to the external peripheral device so that the external peripheral device outputs the desired signal.

16. The image display system of claim 15, wherein the graphic signal comprises a graphic signal received through the Internet.

17. The image display system of claim 14, wherein the external peripheral device is further configured to output the graphic signal and the video signal as separate signals.

18. The image display system of claim 14, wherein the external peripheral device is further configured to output the graphic signal and the video signal in different signal forms.
