The above and/or other aspects will become apparent and more readily appreciated from the following description of the exemplary embodiments, taken in conjunction with the accompanying drawings, in which:
Below, exemplary embodiments will be described in detail.
The display device 1 connects with the peripheral device such as an image device 3. The image device 3 may include a digital versatile disc (DVD) player, a BluRay disc (BD) player, a set-top box, a personal computer (PC), a camcorder, a portable terminal, etc. The peripheral device connected to the display device 1 is not limited to the image device 3. Also, the number of image devices 3 connected to the display device 1 is not limited to one device. Two or more image devices may be connected to the display device 1.
The display device 1 and the image device 3 may form a wireless network (hereinafter, referred to as “wireless connection”). As an example of a wireless network connection mode (hereinafter, referred to as a “wireless connection mode”) in this exemplary embodiment, there are an infrastructure mode, an ad-hoc mode, a DLNA mode, etc. Through this wireless connection mode, the display device 1 and the image device 3 may connect with each other directly as shown in
The display device 1 and the image device 3 may connect with each other not only wirelessly, but also through a predetermined interface for transmitting a video signal and/or an audio signal (hereinafter, referred to as a “video signal”). In this exemplary embodiment, an interface mode between the display device 1 and the image device 3 may include high-definition multimedia interface (HDMI) or an HDMI-consumer electronics control (CEC).
The display device 1 receives information for a wireless connection (hereinafter, referred to as “wireless connection information”) from the image device 3 through the interface for transmitting a video signal, and performs the wireless connection based on the received wireless connection information. For example, the wireless connection of an exemplary embodiment includes connection between the display device 1 and the image device 3 or connection between the display device 1 and the wireless router 3 as described above. The wireless connection information in this exemplary embodiment corresponds to each foregoing wireless connection mode, and contains information needed for a wireless connection in accordance with procedures regulated by these modes. For example, the wireless connection information may include information about at least one of whether the image device 3 is mounted with a wireless adapter, a supportable wireless connection mode (i.e., whether the image device 3 supports the ad-hoc mode), and a current network configuration state (i.e., whether the image device 3 connects with a wireless router, a DLNA server or the like). For example, the wireless connection information may also contain at least one of device identification (ID) of the image device 3, a security key and a security type.
The first communication unit 11 communicates with the image device 3 through an interface for transmitting a video signal. The first communication unit 11 receives wireless connection information from the image device 3.
The video processor 12 performs video processing for displaying an image based on a video signal received through the first communication unit 11. The video processor 12 may perform decoding, scaling, image enhancing, etc.
The display unit 13 displays an image based on a video signal processed by the video processor 12. For example, the display unit 13 may display an image by at least one type among various display types such as a liquid crystal display (LCD), a plasma display panel (PDP), projection, an organic light emitting diode (OLED), etc.
The second communication unit 14 performs wireless communication for a wireless network connection. The second communication unit 14 corresponds to each wireless connection mode, and performs operations needed for a wireless connection in accordance with procedures regulated by these modes. The second communication unit 14 performs communication for a wireless connection based on the wireless connection information received from the image device 3 under control of the controller 15.
The controller 15 generally controls the display device 1. The controller 15 controls the first communication unit 11, the video processor 12 and the display unit 13 to display an image based on a video signal.
The controller 15 receives wireless connection information from the image device 3 through the first communication unit 11, and controls the second communication unit 14 to perform wireless connection based on the received wireless connection information. The controller 15 may include a non-volatile memory (not shown) where a control program for performing the above control is stored, a volatile memory (not shown) where the control program is at least partially loaded, and a microprocessor (not shown) that executes the loaded program.
First, at operation 41, the display device 1 receives wireless connection information from the image device 3 through the first communication unit 11. For example, if the display device 1 connects with the image device 3 through an HDMI cable, the display device 1 performs a discovery algorithm through the HDMI-CEC and receives the wireless connection information from the image device 3.
Then, at operation 42, the display device 1 performs wireless connection through the second communication unit 14 on the basis of the wireless connection information received from the image device 3 through the first communication unit 11.
In the case of a wireless fidelity (Wi-Fi) direct connection as an example of the above-mentioned wireless connection modes, the display device 1 sends the image device 3 a command of request for the Wi-Fi direct connection, and the image device 3 receiving the command enters a group formation procedure. Also, the display device 1 outputting the command starts the group formation procedure for the Wi-Fi direct connection. When the group formation procedure is completed, the Wi-Fi direction connection between the display device 1 and the image device 3 is automatically achieved through a provisioning procedure; in which the display device 1 and the image device 3 exchange a Wi-Fi credential with each other through Wi-Fi simple config (WSC) and achieve Wi-Fi connection. The procedure of establishing a wireless connection is not limited to the above exemplary embodiment, and may be carried out variously in accordance with each of the wireless connection modes mentioned above.
First, at operation 51, the display device 1 receives wireless connection information from the image device 3 through the first communication unit 11.
Then, at operation 52, the display device 1 determines a wireless connection mode to be performed through the second communication unit 14 based on the wireless connection information received from the image device 3 through the first communication unit 11. That is, the display device 1 analyzes the received wireless connection information, and grasps a current wireless network state, thereby determining a proper wireless connection mode. For example, the determined wireless connection mode may be one of the infrastructure mode, the ad-hoc mode, the Wi-Fi direct connection mode, the DLNA mode, etc. as described above. Further, if the image device 3 is connected to the wireless router 5 but the display device 1 is not connected to the wireless router 5, it may be determined to connect the display device 1 and the wireless router 5 to achieve the infrastructure mode. However, this is merely an example. Alternatively, the determination of the wireless connection mode based on the wireless connection information may be varied depending on the current wireless network state.
Next, at operation 53, the display device 1 asks a user whether to carry out the wireless connection based on the determined wireless connection mode. In this case, as shown in
Referring back to
Thus, in the display device 1 according to an exemplary embodiment, the wireless connection is automatically established based on the wireless connection information received from the image device 3, thereby improving a user's convenience. That is, a user can establish the wireless network between the devices even though she has no prior knowledge about the network or the devices. It is therefore more convenient, and time taken during the wireless connection procedures may be reduced.
The display device 1 connects with a plurality of image devices 3a and 3b through an interface for transmitting a video signal. The plurality of image devices 3a and 3b may wirelessly connect with each other. The display device 1 receives wireless connection information from one (e.g., image device 3a) of the plurality of image devices 3a and 3b, and transmits it to the other one (e.g., image device 3b), thereby establishing the wireless connection of the image device 3b.
For example, the image device 3b and the image device 3a may be connected in the ad-hoc mode as shown in
Then, at operation 102, the display device 1 determines a wireless connection mode to be established for the image device 3b on the basis of the wireless connection information received from the image device 3a through the communication unit 11a.
Next, at operation 103, the display device 1 carries out the wireless connection of the image device 3b in accordance with the determined wireless connection mode. That is, the display device 1 transmits the wireless connection information received from the image device 3a to the image device 3b. The image device 3b performs the wireless connection based on the received wireless connection information.
As described above, it may be possible to more easily perform the wireless network connection with at least one peripheral device.
Also, the wireless network connection is performed by receiving the wireless network information from the device connected through the HDMI-CED for transmitting a video signal, the USB for universal communication, etc., and therefore there is no need of a separate configuration for an automatic wireless connection, thereby simplifying configuration and reducing cost.
Although a few exemplary embodiments have been shown and described, it will be appreciated by those skilled in the art that changes may be made in these exemplary embodiments without departing from the principles and spirit of the present inventive concept.
For example, if the plural image devices are connected to the wireless router 5, and are capable of sharing content through the DLNA mode on the basis of the received wireless connection information, the display device 1 asks a user whether to activate a DLNA connection between the devices and allows content to be automatically shared between the devices. In this case, the display device 1 sends a message for driving a DLNA server to the image device providing content, so that the display device 1 can become a DLNA client. Also, such share of the content may be achieved in another wireless connection mode such as the ad-hoc mode or the like.
Also, the display device may connect with a peripheral device by a universal communication standard such as a USB standard or the like, as well as the HDMI-CEC standard for transmitting the video signal according to the foregoing exemplary embodiment, so that it can receive information for the wireless network connection through the universal communication standard.
Further, the foregoing exemplary embodiment illustrates only the display device 1 as a wireless communication device, but is not limited thereto. Alternatively, the foregoing exemplary embodiments may be applied to any electronic device having a wireless communication function.
