FIG. 3 is a control flowchart for explaining a procedure for connecting a display device and a terminal of the image display system in FIG. 1. First, the connection for communication between the display apparatus 100 and the terminals 210, 220, 230, and 240 will be described with reference to FIG. 3.

The display device 100 searches for a terminal that can communicate in operation S100, and transmits access information for notifying the accessible state to the searched terminal in operation S110. In the image display system, since the display device 100 is used as a server for the terminals 210, 220, 230, and 240, the display device 100 needs to collect information about the terminals currently accessible, the terminals accessed by the display device, Attempting to access the information of the terminal of the display device 100 or the like. In other words, the display device 100 searches the terminal to correctly and easily manage the access state of the terminal.

On the other hand, the terminals 210, 220, 230, and 240 can search for the accessible display device 100 via the second communication unit 211 during operation S200. The terminals 210, 220, 230, and 240 can search not only for the display device 100 but also for other terminals that can currently access the display device 100.

The terminals 210, 220, 230, and 240 recognize the accessibility of the display device 100 by receiving the above-mentioned access information from the display device 100 or searching for the request access information for accessing the display device 100 by itself (at operation S210) sex.

In operation S120, the display device 100 establishes a plurality of terminals 210, 220, 230, and 240 that request access between communicable terminals as target terminals to which personal content can be transmitted.

In operation S220, the terminals 210, 220, 230, and 240 request the display device 100 to transmit personal content. In response to the request, the display device 100 transmits personal content to the terminals 210, 220, 230, and 240 in operation S130. Here, the access request signal transmitted from the terminals 210, 220, 230, and 240 to the display device 100 may include a signal for requesting personal content. That is, the display device 100 can regard the access request signal as a content request signal when receiving the access request signal, and transmit personal content to the terminal that transmits the access request signal.

Although not shown, if the target terminal transmits an access release signal for releasing access, the display device 100 releases access to the target terminal that transmits the access release signal.

FIG. 4 is a control flowchart for explaining the image display method in the image display system of FIG. 1. Hereinafter, referring to FIG. 4, the process of changing the shared image I and the personal image II in an interlocked state by the first controller 140 will be described.

First, the display device 100 receives server software from an external server when operating S300. The server software contains information about the shared image I to be displayed on the first display unit 130 and the information about the shared image I to be displayed on the terminals 210, 220, 230, and 240. Information of Personal Image II.

The operation when the display device 100 receives the server software is executed before the personal content is transmitted to the terminals 210, 220, 230, and 240.

The display device 100 processes the received server software through the first controller 140, and then displays the shared image I on the first display unit 130 in operation S310 and transmits the personal content to the requested personal content in operation S320 The terminals 210, 220, 230, and 240.

The terminals 210, 220, 230, and 240 use the second controller 214 to process each of the personal content received via the second communication unit 211, and display the corresponding information on the second display unit 212 during operation S400. Personal Image II. Personal content can include scripts. In this case, the terminals 210, 220, 230, and 240 can download software from an external server, such as a browser capable of processing the script. Since personal content is processed by the browser regardless of the platform, the terminals 210, 220, 230, and 240 do not need to download a separate application for processing personal content. In other words, the terminals 210, 220, 230, and 240 can execute personal content provided from the display device 100 without downloading independent applications for executing various personal content.

In operation S410, the user can input (for example) at one of the terminals via the user input unit 213 to manipulate the personal image II displayed thereon. In operation S420, the second controller 214 processes the personal image II in response to the user's input. For example, in the case of a poker game, the user can perform operations such as betting one of his playing cards, placing a bet, fold a hand, or abandoning the game, and the second The controller 214 changes the personal image accordingly.

In operation S430, the terminals 210, 220, 230, and 240 operated by the user transmit information about the changed personal image II, the received user input, or a control signal based on the user's input to the display device 100.

In operation S330, the display device 100 changes the shared image I to correspond to the received information, that is, corresponds to the changed personal image II and/or the user's input. If a user opens a card when the terminal is interconnected with the display device 100, starts betting, folds or abandons the game, the display device 100 changes the shared image I accordingly.

In operation S340, the display device 100 can change the shared image I when the server software is executed without responding to the user's input. For example, the execution of the server software may allow the display device 100 to become one of the terminals manipulated by the game player and participate in the game. In this case, the shared image I can be changed without user input.

If the shared image I is changed by any means or if information is provided to each of the terminals 210, 220, 230, and 240, the display device 100 individually transmits the information to the respective terminals 210, 220, 230, and 240 in order to change the personal images II corresponding to the terminals 210, 220, 230, and 240, respectively. In operation S350, the display device 100 individually transmits data to the respective terminals 210, 220, 230, and 240 independently of each other so as to individually change the personal images II corresponding to the terminals 210, 220, 230, and 240, respectively. Here, the data may include image-composition information about the personal image II that needs to be changed, as well as various control and command signals.

In operation S440, the terminals 210, 220, 230, and 240 respectively change the personal image II based on the received data.

When receiving user input from one of the multiple terminals 210, 220, 230, and 240, the first controller 140 of the display device 100 correspondingly changes the shared image I and the personal images II of other terminals At least one.

As described above, the shared image I and the personal image II are changed in an interlocked state, and the first controller 140 controls the second controller 214 so that the personal image II of the individual terminals 210, 220, 230, and 240 can be Corresponding to the change of the shared image I or the personal image II of other terminals.

When receiving the user's input, in this exemplary embodiment, the terminals 210, 220, 230, and 240 individually process and change their own personal image II, and provide the user's input to the display device 100 at the same time.

According to another exemplary embodiment, the terminals 210, 220, 230, and 240 may provide the user's input to the display device 100 and then receive from the display device 100 the changed information corresponding to the personal image II related to the user input . In other words, the terminals 210, 220, 230, and 240 transmit the received user input to the display device 100, and all image processing can be performed in the display device 100. In this case, the terminals 210, 220, 230, and 240 are used to display the personal image II depending on the received information.

FIG. 5 is a control flowchart for explaining another image display method in the image display system of FIG. 1.

Basic control operations such as connecting the display device 100 and the terminals 210, 220, 230, and 240 to each other through an access protocol, starting communication, and changing the shared image I and personal image II by the first controller 140 are the same as those in FIG. 3 The basic control operation is the same.

In this exemplary embodiment, if the personal image II must be changed, in operation S360, the display device 100 generates the personal image II and transmits it to the terminals 210, 220, 230, and 240, but does not transmit information about the individual to be changed Image II data, control and command signals. In operation S450, the second controller 214 receives the personal image II generated in the display device 100 and only executes the program for displaying the personal image II on the second display unit 212. In this case, it is advantageous to reduce the load of processing data in the terminals 210, 220, 230, and 240. In addition, it is possible to display personal content regardless of the platforms supported by the terminals 210, 220, 230, and 240, even when the personal content is not a script but an application software.

According to another exemplary embodiment, communication between the plurality of terminals 210, 220, 230, and 240 may be realized. In other words, the terminals 210, 220, 230, and 240 can transmit and receive text or images therebetween. For example, in the case of playing games or taking notes, it is possible to exchange messages with other terminals or draw personal images II to other terminals. The communication between the terminals 210, 220, 230, and 240 can be achieved through short message service (SMS) or peer to peer (P2P).

As is obvious from the above description, shared images and personal images are controlled in an interlocked state, and different images are displayed on the display device communicating with one terminal or multiple terminals at the same time, thereby providing a video similar to the prior art. A new video interface with a different interface. Such a video interface provides a game environment for promoting friendship among multiple users, and an environment for allowing each user to control personal images involved in open shared images in public places.

As described above, according to exemplary embodiments, a display device, a terminal, and an image display method capable of providing a video interface including a shared image and a personal image are provided.
