In order to solve the problems in the prior art, the embodiment of the application provides a display device, which comprises a display, a user interface and a controller. The operational flow diagram of the display device may refer to fig. 6, the controller being configured to perform the steps of:

S101, utilizing the voice assistant application to send received user voice to the voice assistant server;

the controller receives user voice through the user interface, and the user voice in the embodiment of the application is voice for indicating the display device to change channels. The user speech may include a channel name or a channel number. For example, in some feasible embodiments, the transmission procedure of the user voice may be: the user outputs a wake-up word in advance and then outputs the user's voice. The user is connected with the controller based on the wake-up words, so that the controller can respond to the user voice output by the user correspondingly. For example, the user enters the wake word "college classmate" and the user voice "switch to Hunan guard. In some feasible embodiments, for another example, the user enters the wake-up word "college classmate" and user voice "to switch to 57". The present embodiment is merely exemplary to provide two forms of user voice, and the user voice may be, but is not limited to, the two forms in the process of practical application.

In the practical application process, each voice assistant corresponds to a voice assistant identifier, and the voice assistant sends the voice of the user and simultaneously sends the voice assistant identifier to the voice assistant server. Wherein, the voice assistant identifiers are in one-to-one correspondence with the voice assistants, and the voice assistant identifiers can be, but are not limited to, user account numbers, voice assistant IDs, and the like.

In the application, the voice assistant server is configured with a plurality of communication interfaces, and each communication interface is bound with a voice assistant identifier. When the voice assistant server receives the voice assistant identifier, the voice assistant server can call a communication interface corresponding to the voice assistant identifier to establish connection with the corresponding voice assistant, and send the parsed channel changing instruction to the corresponding voice assistant.

The process of the voice assistant server to parse the user's voice will be described with reference to specific examples.

In a possible embodiment, the user voice input by the user is the channel number "10" and the user voice is "switch to channel". The voice assistant outputs the user voice and the voice assistant identification to the voice assistant server. The voice assistant server analyzes the user voice into a channel change instruction:

the analysis process is as follows:

{"inputs":[{"context":{"locale_country":"AU","locale_language":"en"},"intent":"action.devices.EXECUTE","payload":{"commands":[{"devices":[{"id":"8610030090000060000006418a7be726ebffe6d7b20884d409acb98d"}],"execution":[{"command":"action.devices.commands.selectChannel","params":{"channelNumber":"10"}}]}]}}],"requestId":"13593393700909919799"}。

the analysis instruction is as follows: channel number: "10". The voice assistant identifies: id is "13593393700909919799"; the voice assistant server can call the communication interface corresponding to the voice assistant identifier to establish connection with the corresponding voice assistant, and send the parsed channel change instruction to the corresponding voice assistant.

In a possible embodiment, the user enters the user voice as channel name "ABC" and the user voice as "switch tochannelABC. The voice assistant outputs the user voice and the voice assistant identification to the voice assistant server. The voice assistant server analyzes the user voice into a channel change instruction:

The analysis process is as follows:

{"inputs":[{"context":{"locale_country":"AU","locale_language":"en"},"intent":"action.devices.EXECUTE","payload":{"commands":[{"devices":[{"id":"8610030090000060000006418a7be726ebffe6d7b20884d409acb98d"}],"execution":[{"command":"action.devices.commands.selectChannel","params":{"channelCode":"ABC","channelName":"ABC"}}]}]}}],"requestId":"728373555060824393"}。

the analysis instruction is as follows: channelCode: "ABC". The voice assistant identifies: id: "728373555060824393"; the voice assistant server can call the communication interface corresponding to the voice assistant identifier to establish connection with the corresponding voice assistant, and send the parsed channel change instruction to the corresponding voice assistant.

S102, responding to a channel changing instruction issued by the voice assistant server, and receiving an audio and video signal transmitted by a channel corresponding to the channel changing instruction;

the implementation modes of receiving the audio and video signals transmitted by the channels corresponding to the channel changing instruction are various;

for example, a channel identifier may be configured for each channel, and in response to a channel change instruction issued by the voice assistant server, the controller directly invokes a channel whose identifier value matches the channel change instruction, and receives an audio/video signal transmitted by the channel. Wherein, the channel identifier can be a channel name or a channel number.

For example, in a feasible embodiment, the display device may receive audio and video signals transmitted by 100 channels, where the channel identifier corresponding to each channel is 1, 2, 3 and … … respectively, and the channel number is: "10" in response to the channel change instruction issued by the voice assistant server; the controller directly calls the channel corresponding to '10' and receives the audio and video signals by using the channel. In a feasible embodiment, the display device may receive audio and video signals transmitted by 100 channels, where the channel identifier corresponding to each channel is respectively: name 1, name 2, name 3 … … name 100, responding to a channel code of a channel change instruction issued by the voice assistant server, wherein the channel code is 'name 1'; the controller directly calls the channel corresponding to the name 1 and receives the audio and video signals by using the channel.

For another example, the controller stores a channel list for recording the channel names, channel numbers, and correspondence of channels; an implementation manner of receiving an audio/video signal transmitted by a channel corresponding to the channel change instruction may refer to fig. 7, where the controller is further configured to:

s10211, responding to a channel changing instruction issued by the voice assistant server, traversing the channel list to obtain a target channel, wherein the target channel is a channel corresponding to the channel changing instruction;

in a possible embodiment, the controller may receive signals transmitted by 60 channels, and the list of channels may be referred to in table 1.

TABLE 1

Sequence number	Channel name	Channel number	Channel(s)
				1	Name A	1	Channel 1
2	Name B	2	Channel 2
				3	Name C	3	Channel 3
4	Name D	4	Channel 4
				……	……	……	……
60	Name N	60	Channel 60

Responding to a channel changing instruction issued by the voice assistant server, traversing the channel list by a controller according to the sequence of the sequence numbers to obtain a target channel, wherein the target channel is a channel corresponding to the channel changing instruction; for example, in response to a channel number instruction issued by the voice assistant server, "4"; the controller traverses the table 1, and when the 4 th channel number is found, the channel 4 corresponding to the 4 th channel number is determined to be the target channel. Control calls channel 4 and receives audio and video signals using channel 4.

To improve the traversal efficiency of the controller to some extent, in a feasible embodiment, the controller may configure the channel list according to historical data, and in particular, the controller may count the number of times each channel is invoked. And writing the corresponding channel number, channel name and channel into the channel list according to the times. For example, the controller counts how many channels were invoked for the last month of the display device. The arrangement sequence from big to small according to the called times is respectively as follows: the final channel list generated by Hunan channel, zhejiang channel, jiangsu channel, liaoning channel, shandong channel … … may be referred to in Table 2:

TABLE 2

Sequence number	Channel name	Channel number	Channel(s)
				1	Hunan guard	12	Hunan channel
2	Zhejiang toilet	25	Zhejiang channel
				3	Jiangsu guard	6	Jiangsu channel
4	Liaoning toilet	57	Liaoning channel
				4	Shandong guard	24	Shandong channel
……	……	……	……
				60	Name N	60	Channel 60

By adopting the channel list shown in the embodiment, the traversing efficiency of the controller can be improved in some cases. For example, the user prefers the program of Hunan guard, and the user switches channels 5 times before 10-12 points; the channels switched are respectively: hunan channel, qinghai channel, hunan channel, shandong channel, hunan channel. During the first, third and fifth channel changes, the controller traverses one data in the list 2 to determine the target channel, and the traversing speed of the controller is improved.

In a feasible embodiment, the channel name includes: the channel is a generic name, the channel is abbreviated as a short term, and the channel is a generic name, wherein the generic name can be configured according to habits of users, for example: the name of the Hunan broadcast television station may be referred to as a "mango station". The Zhejiang broadcast television group satellite television channel may be referred to as "blueberry station", and the satellite channel under the flag of the Su province broadcast television group may be referred to as "litchi station". Table 3 is a list of channels shown according to one possible embodiment;

According to the technical scheme, user voice input by a user can be reduced, and experience of the user is improved. For example, in one possible embodiment, where the user wants to switch to "Hunan radio station," the user voice input by the user may be "mango station. The voice assistant server analyzes the voice of the user to obtain a switching instruction hannelCode, namely a mango table. And responding to a channel changing instruction channel code issued by the voice assistant server, namely 'mango station', and traversing the table 3 by the controller to obtain a target channel Hunan channel. The controller receives the audio and video data using the Hunan channel.

In a feasible embodiment, the voice assistant server may store a channel name list, where the channel name list user stores a correspondence between a switch instruction and a channel name, where the channel name may include: the channel is a generic name, the channel is abbreviated, and the channel is a generic name. Table 4 is a list of channel names shown according to one possible embodiment;

TABLE 4 Table 4

In this embodiment, only the channel names, channel numbers, and correspondence relation of channels are recorded in the channel list stored in the controller. Table 5 is a channel list shown in the present embodiment;

table 5:

to reduce the amount of data stored by the voice assistant service and the controller, a short term for a channel change instruction may be used in a feasible example.

For example, in one possible embodiment, the user wants to switch to "mango stage", and the user voice input by the user may be "mango stage". The list of channel names stored by the voice assistant server can be referred to in table 4, and the voice assistant server analyzes the voice of the user to obtain a switching instruction hannel code: "Hunan broadcast television station". And responding to a channel changing instruction channel code issued by the voice assistant server, namely 'Hunan broadcast television station', and traversing the table 5 by the controller to obtain a target channel Hunan channel. The controller receives the audio and video data using the Hunan channel.

In order to reduce the data throughput of the controller, in a feasible embodiment, the channel list comprises a first sub-table and a second sub-table; the first sub-table is used for recording the corresponding relation between the channel number and the channel; the first sub-table is used for recording the corresponding relation between channel names and channels; the channel changing instruction also comprises a channel identifier; the controller is further configured to: responding to a channel changing instruction issued by the voice assistant server, and traversing the first sub-table if the channel identifier is a first identifier; if the channel identifier is a second identifier, traversing the second sub-table.

TABLE 6

TABLE 7

Sequence number	Channel number	Channel(s)
			1	12	Hunan channel
2	25	Zhejiang channel
			3	6	Jiangsu channel
4	14	Shanghai channel
			……	……	……
60	60	Channel 60

For example, in one possible embodiment, the channel code is "Jiangsu" as the channel change instruction received by the controller, and the controller identifies the channel code as the first identifier. The controller determines that the Jiangsu channel is the target channel based on the Jiangsu television traversing the first sub-table. In one possible embodiment, the channel number received by the controller is "4", and the controller identifies the channel identifier, which is the second identifier. The controller determines the Jiangsu channel as the target channel based on 4 traversal of the first sub-table.
