In order to realize the quick start of the application, the application key and the application need to be bound before the television is shipped. If some countries and regions do not allow some bound applications to be online, the application start function keys silk-screened on part of the remote controllers are disabled. If through the mode of producing this national remote controller alone, not only with high costs, can't guarantee moreover no longer change afterwards, use when the product shipment after change, will lead to the function inefficacy of quick start button.

In order to solve the problems in the prior art, a first aspect of the embodiments of the present application shows a display device, where the display device includes a display, a user interface, and a controller, where a flowchart of the display device may refer to fig. 7, and the controller is configured to perform the following steps:

s101, responding to a starting instruction, monitoring a network state;

when the user wants to activate the display device, the user may send an activation instruction to the user interface. In some feasible embodiments, the start instruction may be a start instruction sent by the user in the form of voice; the sending process of the start instruction may be: the user outputs the awakening words in advance, then outputs starting instructions, and the user establishes connection with the controller based on the awakening words, so that the controller can respond to the starting instructions output by the user correspondingly. For example, the user enters the wake-up word "congregation classmates" and the start command "turn on the television". In some feasible embodiments, the start instruction may be a start instruction sent by a user through a remote controller; the sending process of the start instruction may be: the user can touch related controls of the remote controller, so that the controller can send corresponding starting instructions, and the controller can make corresponding responses to the starting instructions. For example, the user may trigger the remote controller to send a start command to the controller by clicking a power-on button of the remote controller. The present embodiment provides only two exemplary starting modes of the display device, and the process of sending the start instruction in the process of the actual application may be, but is not limited to, the two modes.

The implementation manner of monitoring the network state may adopt a network monitoring manner that is customary in the art, and the applicant does not make much limitation here.

If the network state is a connected state, executing step S102 to send a list request instruction to a server so that the server calls a key function list;

if the network state is a broken block state, executing step S103 to connect the network;

when the network connection state is connected, step S103 is executed to send a list request instruction to the server;

for example, in one possible embodiment, when the user interface receives the start command, the display device is in a network connection state, and the controller directly sends a list request command to the server. In a feasible embodiment, when the user interface receives the starting instruction, the display device is in a disconnected state, the controller tries to connect to the network and monitors the network connection state in real time, and when the network connection state is connected, the controller directly sends a list request instruction to the server.

The list request instruction at least comprises a device ID of the display device, wherein the device ID can be used as a unique identification value of the display device, and the list request instruction can serve to send the key function list to the corresponding display device based on the device ID.

The server may configure the key function list in the following manner.

For example, in a possible embodiment, the remote controller includes 6 application keys, the server is configured to allocate one application for each key, and the key function list corresponding to the 6 keys can be referred to table 1.

TABLE 1

Serial number	Application key	Application name
				1	Key A	Applications A1
2	Key B	Applications of B1
			3	Key C	Using C1
4	Key D	Applications D1
			5	Key E	Applications of E1
6	Push button F	Using F1

The application configured by the server for the application key is updated in real time, in a feasible embodiment, the application A1 is already offline, and when a list request instruction sent by the controller is received, the key function list configured by the server may refer to table 2;

TABLE 2

As another example, applications supported for use in each country may be different in general, and in order to ensure the accuracy of the server-configured key function list, the list request instruction may include the country in which the display device is located in a feasible embodiment. The server reads the country when receiving a list request instruction; and calling the application supported by the country to generate a key function list. Table 3 list of key functions corresponding to country a. In a possible embodiment, the application B2 does not support the application in country B, and the key function column corresponding to country B can be referred to table 4.

TABLE 3

Serial number	Application key	Application name
			1	Key A	Applications A2
2	Key B	Applications B2
			3	Key C	Applications of C2
4	Push-button D	Using D2
			5	Key E	Applications E2
6	Push-button F	Using F2

TABLE 4

Serial number	Application key	Application name
			1	Key A	Applications A2
2	Key B	Applications G2
			3	Key C	Using C2
4	Key D	Application D2
			5	Key E	Using E2
6	Push button F	Applications of F2

Alternatively, when the display device is in an on state, the controller may send a list request instruction to the server in response to the user touching the country switching control.

In this embodiment, the list request instruction includes the device ID and the country, so that the server can accurately retrieve, based on the country, the relevant information supporting the country to use the application, and generate the key function list according to the relevant information of the application; the server may accurately send the list of key functions to the display device based on the device ID.

For another example, in order to facilitate the user to know the function of each application key corresponding to the application, in some feasible embodiments, a key identifier may be configured for each key, specifically, refer to fig. 1, where an identifier of the key is marked on each application key, for example, the key identifier at the upper left corner is "LIVE TV (LIVE type key)", and the user may select the corresponding key according to the key identifier. In order to ensure the matching between the key identifier and the later-started application, in a feasible embodiment, the list request instruction sent by the controller carries an application function (corresponding to the key identifier), so that the server may configure the key function list based on the application function.

For example, in one possible embodiment, the remote controller includes 6 application keys. The key identifiers corresponding to the 6 application keys are respectively as follows: live, chat, shopping, video, gaming, communication. The list request instruction sent by the controller carries the key identifier, the device ID, and the country where the display device is located, where the functions of the device ID and the country where the display device is located may refer to the foregoing embodiments, which are not described herein again. The server may refer to table 5 for a key function list generated by invoking application data of a corresponding application based on the key identifier;

TABLE 5

Serial number	Application key	Key mark	Application name
				1	Key A	Live broadcast	Applications A3
2	Key B	Chat	Applications B3
				3	Key C	Shopping	Applications of C3
4	Key D	Video	Applying D3
				5	Key E	Game machine	Applications E3
6	Push button F	Communication	Applications of F3

For another example, the server may classify all applications according to functions in advance, when the server receives a list request instruction carrying a key identifier, the server calls a class of applications matched with the key identifier, then selects an application supporting the country where the display device is located from the class of applications as a target application, and configures a key function list based on target application parameters. For example, the following steps are carried out: the applications that match chat may be qq, weChat, nailing, new wave micro blogging International edition, facebook, twitter, line, whats, soul App, toilet MT, exploration App, accompany me App, strange, neighborhood App, tree hole App, scout App, etc.

In a feasible embodiment, if the application comprises a plurality of applications supporting the country where the display device is located, the server can randomly select a target application to generate a key function list; in a feasible embodiment, if the application supporting the country where the display device is located is included, the server can select an application with better stability as a target application to generate a key function list; the embodiment is only an exemplary method for selecting several target applications, and in the process of practical application, the method for selecting the target application may be, but is not limited to, the above methods.

For another example, in order to reduce the data processing amount of the server, each time the server receives a list request instruction, the server compares the list request instruction with the list request instruction received last time, and if the two list request instructions are consistent, the server directly calls the key function list issued last time for the display device to the display device.

By way of example: in a possible embodiment, the display device is turned on at point 8, 20, when the controller of the display device sends a list request command to the server. The server generates a key function list based on the list request instruction, where the process of generating the key function list may refer to the above embodiments, which are not described herein, and the server sends the generated key function list to the display device. At point 10, 25, the display device is powered on again and the display device sends the list request command to the server again. The server compares the list request instruction received by the point 10 and the point 25 with the list request instruction received by the point 8 and the point 20, the two list request instructions are consistent, and the server directly lists the key function generated by the point 8 and the point 20 to the display device.

In a possible embodiment, the display device is turned on at point 8, 20, when the controller of the display device sends a list request command to the server. The server generates a key function list based on the list request instruction, wherein the generation process of the key function list may refer to the above embodiments and is not described herein, and the server sends the generated key function list to the display device. At point 10 and point 25, the display device is turned on again, the display device sends the list request instruction to the server again, the list request instruction received by point 10 and point 25 is compared with the list request instruction received by point 8 and point 20, the two list request instructions are not consistent, the server generates a key function list based on the list request instruction received by point 10 and point 25, the generation process of the key function list may refer to the above embodiments and is not described herein again, and the server sends the generated key function list to the display device.

S104, in response to receiving the key function list, updating the stored key function list by using the received key function list;

there are various ways of updating the stored key function list using the received key function list.

For example, in response to receiving the key function list, the controller may store the key function list, and when the storage of the key function list is completed, the controller deletes the original key function list. Further, in order to ensure that the controller has an available key function list in the period from power-on to completion of storing the key function list, the key function list in the technical scheme shown in the embodiment of the present application is stored in the FLASH memory, so as to ensure that the key function list can be continuously stored in the FLASH memory after each power-off.

For example, in a feasible embodiment, a FLASH memory of the controller stores a key function list issued by the 8 point 20 server. And when the display device is powered on again at 10 o 'clock and 25 o' clock for 03 seconds, the controller of the display device sends a list request instruction to the server. The controller 10 receives the key function list in 25 minutes and 30 seconds, and completes the storage of the key function list in 10 minutes and 25 minutes and 46 seconds. The controller continues to use the 8 o ' clock 20 received key function list from 10 o ' clock 25 min 03 sec to 10 o ' clock 25 min 46 sec. After 10 o 'clock 25 min 46 sec, the controller can utilize the key function list received by 10 o' clock 25 to realize the quick start of the application.

For another example, in order to ensure that the display device stores the key function list in the display device when the display device is in the first use, so that the application keys of the display device can be normally used, in a feasible embodiment, the controller stores a default list before the display device leaves the factory. When the display device is used for the first time and the display device is not networked or the display device cannot acquire the key function list from the server under other conditions, the display device can utilize the default list to realize the quick start of the application.

For another example, in order to reduce the data processing amount of the controller, when the controller receives the key function list each time, the controller compares the key function list with the stored key function list, and if the two key function lists are consistent, the controller does not store the key function list received this time; and if the two key function lists are not consistent, the controller updates the stored key function list by using the received key function list.

For example, the following steps are carried out: in a feasible embodiment, the display device receives the key function list sent by the server at point 8 and stores the key function list. At point 10 and point 25, the display device is turned on again, the display device sends a list request instruction to the server again, at point 10 and point 26, the display device receives the key function list again, the controller compares the key function list received at point 8 and point 20 with the key function list received at point 10 and point 25, and if the two key function lists are consistent, the controller does not store the key function list received at point 10 and point 25, and continues to use the key function list received at point 8 and point 20, so that the application is started quickly.

In a feasible embodiment, the display device receives the key function list sent by the server at point 8 and stores the key function list. At point 10 and point 25, the display device is turned on again, the display device sends a list request instruction to the server again, at point 10 and point 26, the display device receives the key function list again, the controller compares the key function list received at point 8 and point 20 with the key function list received at point 10 and point 25, if the two key function lists are inconsistent, the controller stores the key function list received at point 10 and point 25, and when the storage of the key function list received at point 10 and point 26 is completed, the controller erases the key function list received at point 8 and point 20, and uses point 10 and point 26 to receive the key function list, so that the application is started quickly.

In a feasible embodiment, the display device receives the key function list sent by the server at point 8 and stores the key function list. At point 10 and point 25, the display device is turned on again, the display device sends a list request instruction to the server again, at point 10 and point 26, the display device receives the key function list again, the controller compares the key function list received at point 8 and the key function list received at point 10 and point 25, the two key function lists are inconsistent, the difference is that the applications corresponding to the key D are inconsistent, the controller can delete the key C recorded in the key function list received at point 8 and point 20, the relevant data of the key D is recorded in the key function list received at point 10 and point 26, and the relevant data of the key D is written in the pre-stored key function list, so that the updating of the key function list is completed.

S105, responding to a key instruction, calling a target application parameter in the key function list, wherein the target application parameter is a parameter corresponding to the key instruction;

For example, the controller responds to a key instruction, and reads a key identifier "live" of the key instruction; the controller invokes the application name "application A3" and the application address "address A3". The controller accesses corresponding resources by using the address A3, returns the UI interface by using the resources, and meanwhile traverses a pre-stored starting mode list by using the application A3, wherein the starting mode list is used for recording the corresponding relation between the application name and the starting mode. And the controller determines that the starting mode of the application A3 is APP starting, and sends the UI interface to the corresponding APP.

The key function list is used for recording mapping relations among key identifiers, application addresses and application IDs; table 7 shows a list of key functions according to a possible embodiment;

TABLE 7

Serial number	Application key	Key label	Application ID	Application address
					1	Key A	Live broadcast	ID-A3	Address A3
