The present invention relates to a display apparatus and a control method thereof, and more particularly, to a display apparatus for confirming protocol information of a set-top box connected to a display apparatus and automatically selecting protocol information corresponding to the set-top box to perform communication. It relates to a control method.

Hotels, hospitals and large shopping malls are using a variety of electronic products with Internet functions to enhance the convenience of customers and the efficiency of sales management.

For example, the hotel is equipped with a set-top box that can communicate with the central server in each room to provide management and service of all rooms. The set-top box is connected to the display device of each room to control the situation of the room through the command of the central server or to allow the user of the hotel, such as cloud service or checkout.

At this time, the set-top box is mainly provided and managed by system integration (SI) companies. SI companies have been making their own protocol schemes, so they can communicate between their products, but they do not communicate well between their products. SI companies mainly produce servers, set-top boxes, etc., and display devices connected to them are produced by other manufacturers. Therefore, in order to communicate through set-top boxes, protocols that match the unique protocol information set in the set-top box are used. The information must be set on the display device.

Therefore, when a new display device is provided in a hotel, etc., unique protocol information of the corresponding set-top box should be set in the display device. In this case, there is an inconvenience in that the user must manually enter the protocol information of the set-top box in the display device. Also, if the protocol information of the set-top box is incorrectly written, the communication between the set-top box and the display device does not work properly. There is a problem that needs to reset the protocol information of the set-top box connected to the display device. Thus, if the display device can automatically set the protocol information of the set-top box connected to the display device will provide convenience to the user.

Accordingly, the present invention has been made in view of the problems of the conventional display device as described above, and was created to improve the problem. An object of the present invention is to check the protocol information of the set-top box connected to the display device, thereby communicating with the set-top box.

As shown in FIG. 3, when the set-top box 100 is connected to the communication unit 200 of the display apparatus 1 (S200), the control unit 500 includes a plurality of protocol information stored in the storage unit 600. Select one (S210), and sends a command signal to the set-top box 100 using the selected protocol information (S220).

The control unit 500 determines whether there is a response signal from the set-top box 100 in response to the command signal transmitted in step S220 (S230). When the control unit 500 receives the response signal from the set-top box 100 within a predetermined time (YES in S230), the controller 500 sets the communication with the set-top box 100 using the selected protocol information (S240).

On the other hand, if the control unit 500 does not receive a response signal from the set-top box 100 within a predetermined time (NO in S230), whether there is unused protocol information among the plurality of protocol information stored in the storage unit 600. Determine (S250).

At this time, if there is protocol information not yet used (NO in S250), the control unit 500 returns to step S210 and sequentially uses protocol information not yet used among the plurality of protocol information stored in the storage unit 600. Proceed with the steps.

The control unit 500 transmits a command signal to the set-top box 100 using all the protocol information stored in the storage unit 600, but if there is no response from the set-top box 100 (YES of S250), the user input Opening the window controls the user to directly enter the protocol information corresponding to the set-top box 100 through the input device (S260).

The present invention is not limited to the specific preferred embodiments as described above, and any person having ordinary skill in the art without departing from the gist of the present invention claimed in the claims can make various modifications.
