Abstract

A first wireless device that supports a Wi-Fi direct service includes: a display unit configured to display an entire image of content being displayed by a second wireless device; a communication unit configured to perform a connection setup with the second wireless device; and a processor configured to control the display unit and the communication unit. The processor receives a zoom-in request signal for zooming in a partial image included in the entire image and receives data of the entire image and data of a zoomed-in partial image corresponding to the partial image from the second wireless device based on the zoom-in request signal.

Claims

1. A display device comprising:

a display configured to display information;

a hardware communication unit configured to perform wireless communication with an external device; and

a processor configured to;

control the display to display a letterbox adjacent to a content image being displayed at the external device, the content image received from the external device via the hardware communication unit;

receive a zoom-in signal for zooming-in to a partial region of the displayed content image;

transmit a zoom-in request message to the external device;

according to the transmitted zoom-in request message receive the entire content image and a zoomed-in image corresponding to the partial region from the external device via the hardware communication unit; and

display the entire image at a region where the letterbox was displayed and display the zoomed-in image on a remaining region of the display.

2. The display device of claim 1, wherein the processor is further configured to control the display to concurrently display the entire content image at a first region of the display and the zoomed-in image at a second region of the display.

3. The display device of claim 1, wherein:

the processor is further configured to control the display to display a pointer corresponding to a remote control device; and

the zoom-in signal is a signal for zooming-in to the partial region corresponding to a location of the pointer within the displayed content image.

4. The display device of claim 3, wherein the zoom-in request message comprises location information of the partial region.

5. The display device of claim 4, wherein the location information of the partial region includes coordinates of the pointer within the content image and coordinates of the partial region.

6. The display device of claim 2, wherein when the content image is displayed at the external device in a portrait orientation:

the content image is displayed on the display in a letterboxed format wherein a first letterbox is displayed at a left side of the displayed content image and a second letterbox is displayed at a right side of the displayed content image; and

the first region corresponds to a location where the first letterbox was displayed and the second region corresponds to a remainder area of the display other than the first region.

7. The display device of claim 2, wherein when the content image is displayed at the external device in a landscape orientation, the second region corresponds to an entire area of the display and the first region corresponds to a windowed area within the second region.

8. The display device of claim 7, wherein the processor is further configured to control the display to display a different zoomed-in image at the second region to correspond to movement of a pointer corresponding to a remote control device, wherein the pointer is displayed and moved within the entire content image displayed at the first region.

9. A system for wirelessly displaying content, the system comprising:

a first display device configured to;

display a letterbox adjacent to a content image being displayed at a second display device of the system;

receive a zoom-in signal for zooming-in to a partial region of the displayed content image;

transmit a zoom-in request message to the second display device;

receive the entire content image and a zoomed-in image corresponding to the partial region from the second display device in response to the transmitted zoom-in request message; and

display the entire image at a region where the letterbox was displayed and display the zoomed-in image on a remaining region of the display,

wherein the second display device is configured to;

display the content image;

receive the zoom-in request message from the first display device;

transmit the entire content image and the zoomed-in image to the first display device in response to the zoom-in request message.

10. The system of claim 9, wherein the first display device is further configured to concurrently display the entire content image at a first region of a display of the first display device and the zoomed-in image at a second region of the display of the first display device.

11. The system of claim 9, wherein:

the first display device is further configured to display a pointer corresponding to a remote control device; and

the zoom-in signal is a signal for zooming-in to the partial region corresponding to a location of the pointer within the displayed content image at the first display device.

12. The system of claim 11, wherein:

the zoom-in request message comprises location information of the partial region; and

the second display device is further configured to obtain data of the partial image based on the location information.

13. The system of claim 12, wherein the location information of the partial region includes coordinates of the pointer within the content image and coordinates of the partial region.

14. The system of claim 10, wherein when the content image is displayed at the second display device in a portrait orientation:

the content image is displayed at the first display device in a letterboxed format wherein a first letterbox is displayed at a left side of the displayed content image and a second letterbox is displayed at a right side of the displayed content image; and

the first region corresponds to a location where the first letterbox was displayed and the second region corresponds to a remainder area of the display of the first display device other than the first region.

15. The system of claim 10, wherein when the content image is displayed at the second display device in a landscape orientation, the second region corresponds to an entire area of the display of the first display device and the first region corresponds to a windowed area within the second region.
