Abstract

A display apparatus and a control method are provided in the present disclosure. The display device includes a display configured to display content from a broadcast system or network and/or a user interface; one or more external device interfaces, configured to communicate with one or more external devices according to a communication protocol, where the communication protocol includes a Bluetooth protocol and an infrared protocol; and at least one processor, in connection with the display and the one or more external device interfaces, and configured to execute instructions to cause the display apparatus to perform the control method.

First claim

What is claimed is:

1 . A display apparatus, comprising:
a display, configured to display content from a broadcast system or network and/or a user interface; one or more external device interfaces, configured to communicate with one or more external devices according to a communication protocol, where the communication protocol comprises a Bluetooth protocol and an infrared protocol; and at least one processor, in connection with the display and the one or more external device interfaces, and configured to execute instructions to cause the display apparatus to: in response to an instruction received from a first external device according to a first communication protocol, determine whether the display apparatus is paired and connected with the first external device according to a second communication protocol, the second communication protocol being different from the first communication protocol; in response to determining that the display apparatus and the first external device have been paired and connected according to the second communication protocol, control the first external device to automatically unpair with the display apparatus according to the second communication protocol, to enable the display apparatus to unpair with the first external device; and in response to determining that the display apparatus has not yet paired and connected with the first external device according to the second communication protocol, control the first external device to pair with the display apparatus according to the second communication protocol without a further operation from a user, control the display to present prompt information of a change of a connection state according to the change of the connection state of the display apparatus, and control the display to present pairing success information after the display apparatus has been paired and connected with the external device according to the second communication protocol.

2 . The display apparatus according to claim 1 , wherein the at least one processor is further configured to execute the instructions to cause the display apparatus to:
before the first external device is controlled to pair with the display apparatus, control the display to present a navigation interface for pairing the first external device with the display apparatus according to the second communication protocol, wherein the navigation interface comprises a control which is variable, the control is displayed as a first key for indicating cancelling a pairing operation before the first external device is paired successfully with the display apparatus, and the control is displayed as a second key for indicating skipping to other function configuration interface after the first external device is paired successfully with the display apparatus.

3 . The display apparatus according to claim 1 , wherein the at least one processor is further configured to execute the instructions to cause the display apparatus to:
automatically unpair with the first external device paired with the display apparatus without other operations from the user during unpairing process.

4 . The display apparatus according to claim 2 , wherein the at least one processor is further configured to execute the instructions to cause the display apparatus to:
receive a function instruction from the first external device based on the infrared protocol that requires data transmission according to the Bluetooth protocol; and control the display to present prompt information for prompting the user for a method of sending a pairing request for Bluetooth pairing.

5 . The display apparatus according to claim 4 , wherein the function instruction comprises a trigger effect and function implementation instruction,
before the first external device is not paired with the display apparatus according to the Bluetooth protocol, the function instruction is configured to enable the display apparatus to trigger a pairing according to the Bluetooth protocol; and after the first external device has been paired with the display apparatus according to the Bluetooth protocol, the function instruction is configured to enable the display apparatus to implement a corresponding function instruction.

6 . The display apparatus according to claim 1 , wherein the instruction received from the first external device is generated by long pressing a specific key on a remote controller.

7 . The display apparatus according to claim 1 , wherein the first external device comprises a remote controller supporting the Bluetooth protocol.

8 . A display apparatus, comprising:
a display, configured to display content from a broadcast system or network and/or a user interface; one or more external device interfaces, configured to communicate with one or more external devices according to a communication protocol, where the communication protocol comprises a Bluetooth protocol and an infrared protocol; and at least one processor, in connection with the display and the one or more external device interfaces, and configured to execute instructions to cause the display apparatus to: in response to an instruction received from a first external device according to a first communication protocol, determine whether the display apparatus is paired and connected with the first external device according to a second communication protocol; in response to determining that the display apparatus and the first external device have been paired and connected according to the second communication protocol, control the first external device to automatically unpair with the display apparatus according to the second communication protocol, to enable the display apparatus to unpair with the first external device; and in response to determining that the display apparatus has not yet paired and connected with the first external device according to the second communication protocol, control the first external device to pair with the display apparatus according to the second communication protocol without a further operation from a user, control the display to present prompt information of a change of a connection state according to the change of the connection state of the display apparatus, and control the display to present pairing success information after the display apparatus has been paired and connected with the external device according to the second communication protocol, wherein the at least one processor is further configured to execute the instructions to cause the display apparatus to: in response to a power-on command for the display apparatus, display a navigation interface for pairing the first external device with the display apparatus, wherein the navigation interface comprises a control which is variable depending on a connection state between the first external device and the display apparatus; the connection state comprises a stage of a pairing process; before the first external device is successfully paired with the display apparatus, the control is displayed as a first key for indicating cancelling a pairing operation; and after the first external device is successfully paired with the display apparatus, the control is displayed as a second key for indicating skipping to other function configuration interface.

9 . A control method for a display apparatus, and comprising:
in response to an instruction received from a first external device according to a first communication protocol, determining whether the display apparatus is paired and connected with the first external device according to a second communication protocol, the second communication protocol being different from the first communication protocol; wherein the display apparatus communicates with
