Wireless device supporting Wi-Fi direct service
A wireless device supporting Wi-Fi Direct service includes: a display; a communication unit; and a controller configured to cause: transmitting resolution information including a plurality of resolutions that are supported by the wireless device to a second wireless device; receiving an entire image including a first image and a second image from the second wireless device if a resolution of the first image is not one of the plurality of resolutions; displaying the first image by removing the second image from the received entire image when the entire image is received; and receiving the first image from the second wireless device without the second image if the resolution of the first image is included in the resolution information, the second image being an image that is added to the first image such that a resolution of the received entire image corresponds to one of the plurality of resolutions.
1. A first wireless device supporting Wi-Fi Direct service, the first wireless device comprising:
a display;
a communication unit configured to communicate with a second wireless device; and
a controller configured to:
transmit resolution information to the second wireless device by using Real-Time Streaming Protocol (RTSP), the resolution information including a plurality of resolutions that are supported by the first wireless device;
receive an entire image including a first image and a second image from the second wireless device if a resolution of the first image is not one of the plurality of resolutions;
display the first image by removing the second image from the received entire image; and
receive the first image from the second wireless device without the second image if the resolution of the first image is included in the resolution information,
wherein the second image is an image that is added to the first image such that a resolution of the received entire image corresponds to one of the plurality of resolutions.
2. The first wireless device of claim 1 , wherein the resolution of the entire image is selected by the second wireless device from the plurality of resolutions.
3. The first wireless device of claim 2 , wherein the controller is further configured to cause the communication unit to receive, from the second wireless device, a message indicating that an image having the resolution that is selected from the plurality of resolutions is to be delivered by using the RTSP.
4. The first wireless device of claim 1 , wherein the second image is a black image.
5. The first wireless device of claim 1 , wherein the first image is an image that is currently displayed by the second wireless device when the entire image or the first image is received.
6. The first wireless device of claim 1 , wherein the controller is further configured to cause the display to:
display an image of media content via an entire screen of the display prior to the receiving of the entire image from the second wireless device; and
display the first image via a partial screen of the display by removing the second image after receiving the entire image.
7. The first wireless device of claim 6 , wherein the first image is displayed overlapping the image of media content.
8. The first wireless device of claim 7 , wherein the controller is further configured to cause the display to display an image adjustment window for controlling at least one of a size or transparency of the first image such that the image adjustment window is displayed on a first area of the display while the first image is displayed on a second area of the display.
9. The first wireless device of claim 8 , wherein the controller is further configured to cause the first image to decrease its size in response to an input applied via the image adjustment window such that the decreased size first image overlaps partially with the image of media content.
10. The first wireless device of claim 8 , wherein the controller is further configured to cause the first image to increase its transparency in response to an input applied via the image adjustment window such that the image of media content is visible through the first image with the increased transparency.
11. The first wireless device of claim 6 , wherein the controller is further configured to:
cause the display to display a control window including at least one virtual button for controlling an operation of the second wireless device on a first area of the display while the first image is displayed on a second area of the display; and
control an operation of the second wireless device in response to an input applied via the at least one virtual button.
12. The first wireless device of claim 6 , wherein the controller is further configured to cause the display to display the second image that is restored at a top/bottom or left/right portion of the first image in response to an input for selecting the first image displayed via the partial screen.
13. The first wireless device of claim 12 , wherein the controller is further configured to:
cause the display to display a control window including at least one virtual button for controlling an operation of the second wireless device on an area of the second image; and
control an operation of the second wireless device in response to an input applied via the at least one virtual button.
14. The first wireless device of claim 1 , wherein the controller is further configured to cause the display to:
display the first image on an entire screen of the display without the second image; and
display at least one image adjustment window for adjusting a size or a position of the first image, the at least one image adjustment window overlapping the first image.
15. The first wireless device of claim 1 , wherein the resolution of the first image that is currently displayed by the second wireless device is not included in the plurality of resolutions when a display mode of the second wireless device is a portrait mode.
16. The first wireless device of claim 15 , wherein the controller is further configured to automatically switch the first image to a landscape mode when the display mode of the second wireless device is switched from the portrait mode to the landscape mode.
17. The first wireless device of claim 1 , wherein each of resolutions supportable by the first wireless device corresponds to an aspect ratio of which a horizontal length is longer than a vertical length.
18. The first wireless device of claim 1 , wherein the controller is further configured to detect the second wireless device prior to performing connection setup to communicate with the second wireless device.
19. A method for controlling a first wireless device supporting Wi-Fi Direct service, the method comprising:
communicating with a second wireless device via a communication unit;
transmitting resolution information to the second wireless device by using Real-Time Streaming Protocol (RTSP), the resolution information including a plurality of resolutions that are supported by the first wireless device;
receiving an entire image including a first image and a second image from the second wireless device if a resolution of the first image that is currently displayed by the second wireless device is not one of the plurality of resolutions; and
displaying, on a display, the first image by removing the second image from the received entire image,
wherein the second image is an image that is added to the first image such that a resolution of the received entire image corresponds to one of the plurality of resolutions.
