Such as: the control apparatus 100 transmits a control signal (e.g., a touch signal or a button signal) to the display device 200 via the communicator 130, and the control apparatus 100 may receive the signal transmitted by the display device 200 via the communicator 130. The communicator 130 may include an infrared signal interface 131 and a radio frequency signal interface 132. For example: when the infrared signal interface is used, the user input instruction needs to be converted into an infrared control signal according to an infrared control protocol, and the infrared control signal is sent to the display device 200 through the infrared sending module. The following steps are repeated: when the rf signal interface is used, a user input command needs to be converted into a digital signal, and then the digital signal is modulated according to the rf control signal modulation protocol and then transmitted to the display device 200 through the rf transmitting terminal.

The user input interface 140 may include at least one of a microphone 141, a touch pad 142, a sensor 143, a key 144, and the like, so that a user can input a user instruction regarding controlling the display apparatus 200 to the control apparatus 100 through voice, touch, gesture, press, and the like.

The output interface 150 outputs a user instruction received by the user input interface 140 to the display apparatus 200, or outputs an image or voice signal received by the display apparatus 200. Here, the output interface 150 may include an LED interface 151, a vibration interface 152 generating vibration, a sound output interface 153 outputting sound, a display 154 outputting an image, and the like. For example, the remote controller 100 may receive an output signal such as audio, video, or data from the output interface 150, and display the output signal in the form of an image on the display 154, in the form of audio at the sound output interface 153, or in the form of vibration at the vibration interface 152.

And a power supply 160 for providing operation power support for each element of the control device 100 under the control of the controller 110. In the form of a battery and associated control circuitry.

In some scenes, the remote controller 100 is provided with numeric keys 0 to 9 and direction keys (up, down, left and right), and a user can control the television by operating the remote controller; the graphical user interface of the television can also display a virtual keyboard, and letter keys and number keys 0-9 are arranged on the virtual keyboard.

If the user wants to search the media data on the television, the display interface of the television can display the interface of the virtual keyboard, and the user can complete the function of searching the pinyin initial letters by combining the remote controller and the virtual keyboard. The prior art pinyin initial search process will be described by a specific example:

fig. 2A is a diagram illustrating a prior art text input via a virtual keyboard interface. As shown in fig. 2A, a schematic diagram of a virtual keyboard that includes letter keys a-Z and number keys 0-9 and that provides a user with a pinyin initial search function is shown on a display interface of the television. Taking the example that the user searches for the video of the pig cookie, under the pinyin initial search function, the user needs to select the X-letter key through the direction key of the remote controller and press the enter key first, and then the user needs to select the Z-letter key in the same way. As can be seen from fig. 2A, there is a certain interval between the X-letter key and the Z-letter key, in an alternative manner, the user can press the direction keys of "down, left" (i.e. the route and direction shown by the dotted arrow in fig. 2A) in sequence through the remote controller, that is, the user needs to perform 5 key operations through the remote controller to complete the input of the Z-letter key.

FIG. 2B is a diagram of another prior art text entry via a virtual keyboard interface. As shown in fig. 2B, after the user inputs the "X" and "Z" letter keys in the operation manner shown in fig. 2A, the right side of the display interface of the virtual keyboard displays the results of the XZ search, such as "pig peclet album", "pig peclet first season", "pig peclet seventh season", "pig peclet fourth season", "pig peclet second season", etc., and if the user wants to select "pig peclet seventh season", the user needs to sequentially press the "right, down" (i.e., the route and direction shown by the dotted arrow in fig. 2B) direction keys using the remote controller, that is, the user needs to perform 6 key operations via the remote controller to complete the video selection of "pig peclet seventh season".

As can be seen from fig. 2A and 2B, if the user wants to complete the video search of "pig peclet season seven", 11 key operations are required, which is more operation steps, complicated operation, and low input efficiency for the user.

In order to solve the technical problems, the future input behavior of the user is predicted and is marked by using the key symbols on the remote controller, so that the user can directly input the content to be input by operating the key symbols of the remote controller, the quick input is realized, the operation steps of the search process are simplified, and the input efficiency is improved.

The following describes the technical solutions of the present application and how to solve the above technical problems with specific embodiments. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments. Embodiments of the present application will be described below with reference to the accompanying drawings.

Fig. 3 is a flowchart of a method for searching media data according to an embodiment of the present disclosure. As shown in fig. 3, the method for searching media data includes the following steps:

and receiving the operation of calling out the search interface by the user, wherein the operation of the search interface can be called out by inputting a search instruction through voice or can be called out by selecting a search control in the display interface by the user.

In some embodiments, the search interface includes at least a virtual keyboard, a search text box, and a results display area, where the results display area displays recommended content when no characters are entered, such as when the search interface is just entered, or when a user deletes a search character, and displays search results (which may be a program title corresponding to a search term, or a media asset list) corresponding to the search character when there are characters in the search text box.

In some embodiments, when the search result is a program title, the media asset list corresponding to the search term may be further filtered by selecting the program title to filter out the media asset list corresponding to the program title.

In some embodiments, after presenting the search interface, the following steps are performed:

and step S301, receiving the input first character.

The execution main body of the method is the television, a virtual keyboard can be displayed in a graphical user interface of the television, a plurality of character controls are arranged on the virtual keyboard, and the character controls are used for generating a character input instruction when being selected.

The first character in this step is one of the characters characterized by the character control on the virtual keyboard. In an alternative embodiment, the characters represented by the character controls on the virtual keyboard include letters and numbers. The user can input the first character by operating the remote controller of the television. Take the example where the first character is a letter on a virtual keyboard. In an optional scenario, a user may input the first pinyin letter of the name of the media data to be searched on the virtual keyboard by operating a remote controller, for example, a direction key of the remote controller, where the first pinyin letter of the name of the media data is the first character. For a specific process of how to input the first character on the virtual keyboard, reference may be made to the description of the embodiment of fig. 1A and fig. 1B, and details are not described here again.

The first character in this embodiment may be one character or a plurality of characters, which is not specifically limited in this embodiment.

And step S302, displaying recommended symbols at least one second character position on the virtual keyboard respectively.

In this embodiment, the at least one second character is a character to be input predicted according to the first character, each second character further corresponds to a recommended symbol, the recommended symbol is a key symbol on a control panel of the remote controller, and different second characters correspond to different recommended symbols.

Before the television respectively displays the recommended symbol at the position of at least one second character on the virtual keyboard, the display interface of the virtual keyboard needs to be modified according to the recommended symbol, so that the recommended symbol corresponding to the second character is displayed at the position corresponding to the second character on the virtual keyboard, and a quick input reference is provided for a user. The position corresponding to the second character includes a display position within a preset range around the display position of the second character, for example, a gap position between the display position of the second character and the display position of an adjacent character on the virtual keyboard, for example, a display position of an upper right corner of the second character. And meanwhile, establishing a mapping relation between the second character and the recommended symbol, so that the second character can be mapped to a specific second character according to the input recommended symbol.

In some embodiments, the television modifies the display interface of the virtual keyboard according to the recommended symbol, including: and determining the display position of the second character on the virtual keyboard, determining the display position of the recommended symbol according to the display position of the second character, and displaying the recommended symbol at the display position of the recommended symbol. The user searching for a video of "pig cookies" is still used here as an example. As shown in fig. 4, when the television acquires a plurality of second characters "Z" and "H" and acquires that the recommended symbols corresponding to "Z" and "H" are

numbers

1 and 2, respectively,

numbers

1 and 2 are displayed beside the display positions of "Z" and "H" on the virtual keyboard, for example, in the upper right corner.

In some embodiments, the virtual keyboard is displayed on a first layer, the recommended characters are displayed on a second layer, the second layer is located above the first layer, and the second layer is a transparent layer.

In some embodiments, the display position of the second character in the first layer on the virtual keyboard is determined, and the display position of the recommended symbol in the second layer is determined according to the display position of the second character, and the recommended symbol is displayed at the display position of the recommended symbol. The user searching for a video of "pig cookies" is still used here as an example. As shown in fig. 4, when the television acquires a plurality of second characters "Z" and "H" and acquires that the recommended symbols corresponding to "Z" and "H" are

numbers

1 and 2, respectively, the display positions of "Z" and "H" on the virtual keyboard are determined to be (X1, Y1), (X2, and Y2), respectively, and further the positions of the

numbers

1 and 2 in the second layer are determined to be (X1+ i, Y1+ i), (X2+ i, and Y2+ i) according to a preset algorithm. Of course, the specific position change can be changed according to the design of research personnel, and only the marking effect is needed.

It should be noted that the recommended symbol in this embodiment may be any key symbol on the control panel of the remote controller, including a numeric key, a direction key, and the like.

Step S303, according to the received first key value, determining the input of the target character at the position of the first recommended symbol corresponding to the first key value.

The first key value is a key value sent by the remote controller when a trigger is received by a first key symbol in key symbols on a control panel of the remote controller, the first key symbol is the same as the first recommendation symbol, and the first recommendation symbol is one of the recommendation symbols.

After the recommendation symbols are displayed on the virtual keyboard of the television, a user can visually see the recommendation symbols, further select one of the recommendation symbols, and press a first key symbol corresponding to the selected recommendation symbol in the key symbols on the control panel of the remote controller, wherein the recommendation symbol selected and pressed by the user is the first recommendation symbol, and the user inputs a target character on the virtual keyboard corresponding to the first recommendation symbol through the remote controller. Still taking fig. 4 as an example, the

numbers

1 and 2 are keys on the control panel of the remote controller, so that the user can directly press the

number key

1 or 2 on the remote controller to input "Z" or "H".

In some embodiments, the first key value may be replaced by a first instruction, the first instruction may be generated by a key of a remote controller, or may be generated by a voice component according to a received voice, and the voice component may be in the remote controller or on the television body. The first instruction corresponds to the first recommended symbol, and the first instruction is used for enabling the television to inquire the recommended symbol corresponding to the first instruction according to a preset relation, for example, according to a mapping relation between the instruction and the recommended symbol, or a mapping table or other association modes. And then determining a corresponding second character according to the recommended symbol.

And step S304, searching media data according to the first character and the target character.

Specifically, when the television searches for media data according to the first character and the target character, the method includes: and sending the first character and the target character to a server, searching media data by the server according to the first character and the target character, and returning a media searching result to the television. For example, after the user inputs "Z" by pressing the number key 1 on the remote controller, and the search condition displayed in the search bar on the virtual keyboard is "XZ", the television performs a media data search according to "XZ", and the search result may be referred to as a search result list displayed on the right side in fig. 4.

The method includes the steps that input first characters are received, wherein the first characters are one of characters represented by character controls on a virtual keyboard, and recommended symbols are respectively displayed at positions of at least one second character on the virtual keyboard, wherein the at least one second character is a character to be input and is predicted according to the first characters, the recommended symbols are key symbols on a control panel of a remote controller, and the recommended symbols corresponding to different second characters are different; then, according to the received first key value, determining the input of a target character at the position of a first recommended symbol corresponding to the first key value, wherein the first key value is a key value sent by the remote controller when a trigger is received by the first key symbol in the key symbols on the control panel of the remote controller, the first key symbol is the same as the first recommended symbol, and the first recommended symbol is one of the recommended symbols; and finally, searching media data according to the first character and the target character. Because the recommendation symbol is a key symbol on the control panel of the television remote controller, a user can directly operate the remote controller, press the corresponding recommendation symbol on the remote controller and quickly complete the input of the second character, thereby simplifying the operation steps of the user input and improving the input efficiency.

In addition, after step S304, the present embodiment may further determine the first character input last time by the user and the target character input according to the first recommended symbol at the current time as the first character together, and continue to perform step S302. For example, in the example of the user searching for a pig cookie, after the user inputs "X" through the remote controller and inputs the character "Z" determined according to the first recommended symbol through the remote controller, the tv set may determine "XZ" as the first character and continue to predict the second character, for example, "P".

In some embodiments, before displaying the recommended symbol at the at least one second character position on the virtual keyboard, respectively, the method of this embodiment further includes: at least one second character is obtained from the first character. Specifically, after receiving the first character, the television may obtain at least one second character from the television itself, or obtain at least one second character from another device other than the television, for example, from a server.

If the television acquires at least one second character from the television, the television predicts that the character to be input by the user is executed according to the first character. Taking the example of the user searching for the video of the piglet peclet, after the user inputs the first character "X" on the search interface of the television, the television predicts that the second character to be input by the user is "Z" according to the first character "X" input by the user.

If the television acquires at least one second character from other equipment except the television, predicting that the character to be input by the user is executed by other equipment except the television according to the first character. Specifically, taking the server as an example, the television set sends a prediction request including a first character to the server, and the server predicts a second character to be input by the user according to the first character and returns the second character to the television set. Still taking the example here of the user searching for the video of "pig peck", the television set sends the first character "X" to the server, which predicts the second character to be input by the user as "Z" from the first character "X", and returns the predicted second character "Z" to the television set.

In some embodiments, after obtaining at least one second character according to the first character, the television set may further obtain a recommended symbol corresponding to the second character. For the television to obtain the recommended symbol corresponding to the second character, at least two different implementations can be adopted as follows:

in an alternative embodiment, the television may randomly determine that one of the key symbols on the control panel of the remote controller is the recommended symbol corresponding to the second character.

In another optional implementation manner, the television may further obtain the recommendation probability corresponding to the second character, and determine the recommendation symbol according to the magnitude order of the recommendation probability corresponding to the second character. In some embodiments, the server may determine recommendation probabilities corresponding to the second characters, send each second character and its corresponding recommendation probability to the television, and determine the recommendation symbol according to the recommendation probability. The server can also determine the recommendation probability corresponding to the second character, determine the corresponding recommendation symbol according to the recommendation probability corresponding to each second character, and then return the second character and the corresponding recommendation symbol to the television.

When the recommendation symbol is determined according to the order of the recommendation probability corresponding to the second character, the recommendation symbol may include a number, and the key symbol includes a number corresponding to a numeric key on a control panel of the remote controller, the recommendation symbol of the second character may also be determined according to the number of the numeric key on the remote controller, that is, the number of the numeric key is inversely related to the recommendation probability of the second character, for example, the larger the recommendation probability of the second character is, the smaller the number of the numeric key corresponding to the second character is, and conversely, the smaller the recommendation probability of the second character is, the larger the number of the numeric key corresponding to the second character is.

Still taking fig. 4 as an example for illustration, if the second character obtained by the television includes "Z" and "H", and the recommendation probability corresponding to "Z" is greater than the recommendation probability of "H", the television may determine that the recommendation symbols corresponding to "Z" and "H" are

numbers

1 and 2, respectively, and

display numbers

1 and 2 beside the display positions of "Z" and "H" on the virtual keyboard, for example, in the upper right corner, respectively.

In the above embodiments, it is described that the television set may obtain the at least one second character from itself, or may obtain the at least one second character from another device, such as a server, besides the television set. The following will respectively detail the process of how to determine the at least one second character in the above two embodiments:

in an embodiment where the television set obtains at least one second character from itself:

in a first alternative embodiment, obtaining at least one second character from a first character comprises: acquiring historical input behaviors of a user; and predicting at least one second character according to the sequence of the characters input in the historical input behaviors of the user and the first character. Specifically, the television stores the historical input behavior of the user, and after receiving the first character, the television can determine at least one second character to be input by the user according to the first character and the sequence of the characters input in the historical input behavior of the user.

When the television determines at least one second character to be input by the user according to the first character and the sequence of the characters input in the historical input behaviors of the user, the second character can be determined according to the sequence of the characters input in the historical input behaviors including the latest historical moment of the first character, or the second character can be determined according to the sequence of the characters input in the historical input behaviors including the most characters.

The following describes, by way of a specific example, an implementation process for determining a second character according to a sequence of characters input in a history input behavior including a recent history time of a first character:

for example, if the first character is "X", the historical input behaviors of the user are sorted in descending order of time, which are: time: 17/7/17/2020, input behavior: a piggy cookie; time: at 09/7/17/2020, the input action is: the redemption of xiaoshenke; then it can be determined that there is a high probability that the second character that the user will enter is "Z" based on the most recent entry behavior "piggy-peck" and the first character "X" in chronological order.

The following describes, by way of another specific example, an implementation process for determining the second character according to the order of characters input in the historical input behaviors that include the most first characters:

for example, if the first character is "X", statistics are performed on the historical input behavior of the user over a period of time, which are: time: 17/7/17/2020, input behavior: a piggy cookie; time: 14, 7/17/2020, input behavior: a piggy cookie; time: at 12 days 7, 17 and 2020, the input action is: a piggy cookie; time: at 09/7/17/2020, the input action is: the redemption of Shortsek. It can be seen that the most frequent search by the user during this time period is "piggy-peck", and it can be determined from "piggy-peck" and the first character "X" that there is a high probability that the second character to be entered by the user is "Z".

In a second alternative embodiment, obtaining at least one second character from the first character includes: inputting the first character into a preset prediction model to obtain at least one second character; the preset prediction model is obtained by training according to the sequence of characters input in the historical input behaviors of the current user or a plurality of users.

The prediction Model includes Hidden Markov Model (Hidden Markov Model), Conditional Random Field Model (Conditional Random Field), and various Model architectures of deep neural network. The application does not limit what predictive model is used.

In this embodiment, the preset prediction model is stored in the television, and the preset prediction model is obtained by training according to the sequence of the characters input in the historical input behavior of the user, which means that the user of the prediction model and the input user of the first character are the same user, so that one prediction model can be trained for each user, and the prediction model and the user have a one-to-one correspondence relationship. On the basis of this embodiment, the method of this application further includes: the method comprises the steps of obtaining a user account, determining a prediction model corresponding to a user according to the user account and the corresponding relation between the user account and the prediction model, and inputting a first character into the prediction model corresponding to the user to perform character prediction.

In this embodiment, the preset prediction model is obtained by training according to the order of the characters input in the historical input behaviors of the plurality of users, where the plurality of users may or may not include the input user of the first character. The predictive model of the present embodiment may be applied to any one user. In some embodiments, the plurality of users may be group users, e.g., a paid user group, a non-paid user group, a province user, and the like. Or all users including paid user group, non-paid user group and province A user, wherein the users are not divided into groups.

In an embodiment where the television set obtains at least one second character from the server:

in a first alternative embodiment, obtaining at least one second character from a first character comprises: sending the first character to a server; and receiving at least one second character determined by the server according to the first character and the sequence of the characters input in the historical input behaviors of the user. For a specific implementation manner in which the server determines the at least one second character according to the first character and the sequence of the characters input in the historical input behavior of the user, the description may be specifically referred to in the foregoing implementation manner, and details are not repeated here, similarly to an implementation manner in which the television determines the at least one second character according to the first character and the sequence of the characters input in the historical input behavior of the user.

In a second alternative embodiment, obtaining at least one second character from the first character includes: sending the first character to a server; receiving at least one second character determined by the server according to the first character and a preset prediction model; the preset prediction model is obtained by training according to the sequence of characters input in the historical input behaviors of the user or a plurality of users. In this embodiment, a preset prediction model is stored in the server.

For an embodiment in which the television acquires at least one second character from the server, similar to the embodiment in which the television acquires at least one second character from itself, reference may be specifically made to the description of the foregoing embodiment, and details are not described here again. For a specific implementation in which the server determines the at least one second character according to the first character and the preset prediction model, similar to the implementation in which the television determines the at least one second character according to the first character and the preset prediction model, reference may be specifically made to the description of the foregoing implementation, and details are not described here.

The following describes in detail the process of determining the second character according to the first character by the television or the server according to the above embodiment with reference to fig. 5:

in this embodiment, the input behavior of the user includes a behavior type and a behavior value; the behavior types comprise a selection behavior of a pinyin prefix, a selection behavior recommended by a title, a video selection behavior and the like.

The user can switch among different behavior types, and under the same behavior type, the user can continuously perform more than one input behavior and generate more than one continuous behavior numerical value. For example: the user can select X and then Z in the process of selecting the pinyin prefix, which is two user behaviors. For another example: after the user inputs the pinyin prefix, the title id1 can be selected first and then the title id2 can be selected in the related title recommendation, so that the n consecutive behaviors of the user can be expressed as a user behavior sequence: [ action type 1-action value 1, action type 2-action value 2, … …, action type n-action value n ].

Referring to fig. 5, in the drawing, [ behavior type 1, behavior value 1], [ behavior type 2, behavior value 2], [ behavior type 3, behavior value 3] … … [ behavior type t-1, behavior value t-1], [ behavior type t, behavior value t ] are historical input behaviors of the user, and the historical input behaviors have a sequence, where t represents the current time, and the user input behavior at the time t +1 can be predicted according to the user input behaviors at and before the time t.

The user input behavior obtained by the television or the user input behavior returned to the television by the server includes a behavior type, a behavior value, and a number key order corresponding to the remote controller, and the specific form is as follows:

{ type: character input, value: Z, order:1}, whose meaning is: the type of action to be entered by the user is character input and the character is Z, and the recommended symbol corresponding to the character is numeric key 1 of the remote controller.

{ type: character input, value: W, order:2}, whose meaning is: the type of action to be input by the user is character input and the character is W, and the recommended symbol corresponding to the character is the numeric key 2 of the remote controller.

{ type: character input, value: C, order:3}, whose meaning is: the type of action to be input by the user is character input and the character is C, and the recommended symbol corresponding to the character is the numeric keypad 3 of the remote controller.

It should be noted that the training of the prediction model may be performed on the television, may be performed on the server, or may be performed on other devices besides the television and the server, and then the trained prediction model is stored on the television or the server.

In addition, the embodiment may also update the trained prediction model at regular time, so that the prediction accuracy of the prediction model is higher, and a new prediction model is obtained by training according to a new input behavior of the same user or new input behaviors of multiple users.

In the above, a specific implementation of determining a corresponding recommended symbol for the second character is introduced, and on the basis of the above embodiment, the method of this embodiment may further include: at least one search result is obtained based on the first character.

In some embodiments, obtaining at least one search result from the server based on the first character comprises:

step a1, sending the first character to the server.

And step a2, receiving at least one search result returned by the server.

Wherein at least one of the search results is media data to be searched predicted by the server based on the first character.

Specifically, the television may send the first character to the server, and the server determines at least one search result in the video database according to the first character and returns the at least one search result to the television.

Step a3, displaying a recommendation symbol at the position corresponding to each search result on the virtual keyboard.

And the recommendation symbol corresponding to each search result is different, and each second character is different from the recommendation symbol corresponding to each search result, wherein the recommendation symbols are key symbols on a control panel of the remote controller.

In this embodiment, the television or the server may recommend a plurality of user input behaviors of different behavior types, for example:

{ type: title recommendation, value: pig Peclet Collection, order:4}, which means: the type of action to be entered by the user is a title recommendation, and the title is a pig cookie set, the title recommendation corresponding to the recommendation symbol being the numeric key 4 of the remote control.

{ type: title recommendation, value: fourth season of oriented life, order:5}, with the meaning: the type of the action to be input by the user is a title recommendation, and the title is the fourth season of the life, and the corresponding recommendation symbol of the title recommendation is the number key 5 of the remote controller.

The characters and the titles above are all recommended to the user as recommendation results.

For example, after the user inputs "X" through the remote controller and inputs the character "Z" determined according to the first recommended symbol through the remote controller, the "XZ" is the first character, and the television can acquire the second character "P" and the search results "pig cookie set", "pig cookie first season", "pig cookie seventh season", "pig cookie fourth season", "pig cookie second season", and the like according to the "XZ". The recommendation symbols may be displayed for both the second character and the search result, as shown in fig. 6, the recommendation symbol "1" may be displayed at a position corresponding to the display position of the second character "P", and the recommendation symbols "2", "3", "4" may be displayed at positions corresponding to the display positions of the search results "pig cookie set", "pig cookie first season", and "pig cookie seventh season", respectively.

The specific implementation process of how to determine the recommended symbol for the second character and the search result is similar to the implementation process of determining the recommended symbol for the second character, and reference may be specifically made to the implementation process of determining the recommended symbol for the second character, which is not described herein again.

If the step of obtaining at least one second character according to the first character is performed at the television, the embodiment of obtaining at least one search result by the television includes the steps a1 to a 3; if the step of obtaining at least one second character according to the first character is performed at the server, at this time, since the television set has previously sent the first character to the server to obtain at least one second character, the embodiment of obtaining at least one search result by the television set includes the above step a2 and step a 3.

In some embodiments, predicting the media data to be searched based on the first character may include at least four implementations as follows:

in a first alternative embodiment: and the television predicts the first character according to the sequence of the characters input in the historical input behaviors of the user to obtain at least one search result.

In a second alternative embodiment: and the television inputs the first character into a preset prediction model, and at least one search result is obtained through prediction of the preset prediction model.

In a third alternative embodiment: the television sends the first character to the server; and the server predicts the first character according to the sequence of the characters input in the historical input behaviors of the user to obtain at least one search result.

In a fourth alternative embodiment: the television sends the first character to the server; and the server inputs the first character into a preset prediction model, and at least one search result is obtained through prediction of the preset prediction model.

In the above embodiments, the embodiment is described in which the user performs the shortcut input through the remote controller, and in order to distinguish the shortcut input from the normal input, in some embodiments, the shortcut input of the above embodiments may be further configured as a selective function, specifically: after receiving a first character input by a user through a remote controller, judging whether the user starts a shortcut input function or not; if the user opens the shortcut input function, executing the steps of the embodiment of the media data searching method of the above embodiment; and if the user does not start the shortcut input function, executing a normal remote controller command.

In some embodiments, after obtaining the recommended characters, the user may use the shortcut input function described in this embodiment, and may also use the related art key operation to input the characters that the user wants to input.

For example, if the user wants to input the next year of life (the first pinyin letter: XWDSHDSG), after the user inputs X, the user can quickly complete the user input according to the recommended character W displayed on the display interface of the television and the recommended symbol corresponding to W, or can input W by using the conventional method, i.e., [ left key, ok ].

For the television, after receiving the characters input by the user through the remote controller, the television can also compare the characters input by the user through the remote controller with the recommended characters, and if the characters input by the user through the remote controller do not belong to the recommended characters, a general remote controller command is executed; if the character input by the user through the remote controller belongs to the recommended character, step S302 is performed.

For example, the user wants to input a cheerful (XHX), and after the user inputs "X", the recommended characters determined by the server include "Z", and the next character H that the user wants to input does not belong to the recommended characters of the server, at which time, the user can press an up button using the remote controller to move the input focus to H step by step. Since the user does not select H to press the enter key, step S302 does not need to be performed. When the user selects H and presses the enter key, step S302 is performed to re-recommend.

That is, when the instruction input by the user is an instruction corresponding to the non-recommended character, the corresponding operation of the instruction is executed, and the display of the recommended character is cancelled. After the input command finishes inputting a new character, the character recommending process is restarted.

In some embodiments, the recommended characters may be the same as characters represented by some controls in the virtual keyboard, and therefore, after receiving an input from a user, it is necessary to determine whether a recommended character is currently displayed, if a recommended character is displayed, it is determined whether an input instruction corresponds to the recommended character, if a corresponding first recommended character exists, a second character to be input is determined according to a mapping relationship between the recommended character and the second character, if a corresponding recommended character does not exist, an operation corresponding to the instruction is determined, and the operation is executed, for example, in fig. 4, the recommended character is 1, 2; the corresponding character control is Z, H. At this time, if the instruction input by the user through the remote controller or the voice corresponds to '1', the corresponding recommended character exists, and the character needing to be input is determined to be 'Z' according to the mapping relation between the recommended character '1' and the character control 'Z'. If the instruction input by the user through the remote controller or the voice represents '3' (the key value of the numeric key 3 or the voice instruction 'three'), the corresponding recommended character does not exist, then the corresponding operation of the instruction is judged to be the input of the character 3 in the virtual keyboard, the input of the character 3 is executed, the previous recommended character is cancelled, and the recommended second character is determined again according to the character '3'. If the user represents that the command input by the remote controller or the voice moves upwards, the corresponding recommended character does not exist, then the corresponding operation of the command is judged to be the movement of the focus in the virtual keyboard, the focus is moved on the basis that the original focus is located at the position of the Z control, the previous recommended character is cancelled, and the recommended second character is determined after the newly input character is determined by the user again. In some embodiments, after receiving the input of the user, if it is determined that the recommended character is not currently displayed, directly determining an operation corresponding to the instruction, and executing the operation.

The above process will be described in detail below, taking as an example an embodiment in which the server predicts the second character from the first character:

in an optional example, a user inputs a character by using a remote controller, presses a confirmation key, if the television determines that the user starts a shortcut input function, the television sends the latest operation behavior of the user and the character to a server, and the server predicts the next input behavior of the user and the probability of the input behavior according to n input behaviors of the user before the current moment and sends the input behaviors (including a behavior type and a behavior value) and the predicted probability corresponding to the input behavior to the television.

In some embodiments, the server may also use 0-9 for sequential numbering according to the predicted probability of input behavior from large to small in order to recommend the user with the recommended symbol most likely selected by the user.

In order to avoid useless recommendation, the server may also number k behaviors with the highest probability, for example, k <10, or set a threshold, and when the probability is lower than the threshold, no recommendation is performed; and when the probability is larger than or equal to the threshold value, recommending.

In addition, since the key of 0 is usually located at the lowest part or corner of the remote controller, the user is inconvenient to operate, and the recommended symbol may be numbered from 1 to 9 in this embodiment.

For example, the user inputs a character X using the pinyin initial search function, and presses a confirmation key using the remote controller, and the behavior type of the input behavior received by the television is letter input, and the value is X. The request server provides a shortcut input recommendation, and the request content comprises the following behavior types: letter input, and behavior value: and X, the server receives the request, takes the behavior type and the behavior value X as the latest behavior, and forms a user input behavior sequence with the n historical behaviors of the user, and inputs the user input behavior sequence into a prediction model to obtain the prediction result of the next behavior.

For example, the predicted next behavior includes: inputting characters Z, wherein the probability is 80%; inputting characters W, wherein the probability is 12% of the character input C, and the probability is 6%; selecting a title recommendation: pig Peckey collection with a probability of 1%; selecting a title recommendation: piglet peclet collection with a probability of 0.5%.

In some embodiments, to simplify the user operation, the server may also send the 3 recommended characters with the highest probability, and numbering starts from 1.

Fig. 7 is a flowchart of a method for searching media data according to an embodiment of the present application. As shown in fig. 7, the method for searching media data includes the following steps:

step S701, a character prediction request is received.

The main execution body of the embodiment is other devices than the television, such as a server.

In the embodiment, after a user inputs a first character on a virtual keyboard, a television generates a character prediction request according to the first character and sends the character prediction request to a server; wherein the character prediction request includes a first character, the first character being one of the characters characterized by the character control on the virtual keyboard.

Step S702, at least one second character is determined according to the first character.

Wherein the at least one second character is a character to be input predicted from the first character.

In some embodiments, the server may determine the at least one second character according to the first character and a precedence order of characters input in the historical input behavior of the user, or may determine the at least one second character according to the first character and a preset prediction model.

For a specific implementation process of determining at least one second character according to the first character and the sequence of the characters input in the historical input behavior of the user, and determining at least one second character according to the first character and a preset prediction model, reference may be made to the description of the foregoing embodiment, and details are not described here.

And step S703, determining a corresponding recommended symbol for each second character.

The recommended symbols are key symbols on a control panel of the remote controller, and the recommended symbols corresponding to different second characters are different.

In this embodiment, the server may randomly determine a corresponding recommended symbol for each second character, or determine a magnitude order of the recommended probabilities corresponding to the second characters, and determine the recommended symbol according to the magnitude order of the recommended probabilities corresponding to the second characters. For example, the description of the foregoing embodiment may be referred to, and details are not repeated here, where the recommendation symbol corresponding to each second character is randomly determined, the magnitude order of the recommendation probability corresponding to the second character is determined, and a specific implementation process of the recommendation symbol is determined according to the magnitude order of the recommendation probability corresponding to the second character.

Step S704, determining at least one search result according to the first character.

Wherein at least one search result is media data to be searched predicted according to the first character.

In some embodiments, predicting the media data to be searched based on the first character may include at least two implementations as follows:

in a first alternative embodiment: and the server predicts the first character according to the sequence of the characters input in the historical input behaviors of the user to obtain at least one search result.

In a second alternative embodiment: and the server inputs the first character into a preset prediction model, and at least one search result is obtained through prediction of the preset prediction model.

Step S705, the second character, the recommended symbol corresponding to the second character and at least one search result are sent to the television.

The server sends the second character, the recommended symbol corresponding to the second character and at least one search result to the television, and the television can directly modify the virtual keyboard according to the second character, the recommended symbol corresponding to the second character and the at least one search result, namely, the recommended symbol is displayed at the position corresponding to each second character on the virtual keyboard.

Fig. 8 is a flowchart of a method for searching media data according to another embodiment of the present application. As shown in fig. 8, the method for searching media data is applied to a television, and a virtual keyboard is displayed in a graphical user interface of the television, and the method includes the following steps:

and step S801, receiving an input first control instruction.

Referring to fig. 1, the user may input the first control command by operating the remote controller, and send the first control command to the television.

Step S802, determining a first character according to the first control instruction and the first character control at the focus position, and displaying the first character in the search text box.

The first character control is one of the character controls on the virtual keyboard, the focus position is a position indicated by a cursor on the virtual keyboard, and a character indicated by the character control corresponding to the position where the cursor stays on the virtual keyboard is the first character. For example, please continue to refer to fig. 2A, if the user selects a character control on the virtual keyboard by operating the remote controller, and the character indicated by the character control is "X", in the process, "X" is the first character, "X" corresponds to the first character control, and the command input by the user through a series of remote controller operations is the first control command. When the television set determines the first character to be input, the first character is displayed in the search text box, for example, the search text box displays "X", and when the user inputs "Z" after performing step S801 and step S802 again, the search text box of fig. 2A displays "XZ".

Step S803, sending a search instruction containing the first character to the server, so that the server determines the first media data according to the first character, and predicts at least one second character according to the first character.

Specifically, after receiving a first character, the television generates a search instruction according to the first character and sends the search instruction to the server, the search instruction comprises the first character, the server analyzes the first character after receiving the search instruction to obtain the first character, determines first media data according to the first character, and predicts at least one second character according to the first character.

The implementation process of the server predicting at least one second character according to the first character is described above, and reference may be specifically made to the description of the foregoing, which is not described herein again. And the process of the server determining the first media data according to the first character means that the media data search is performed according to the first character, for example, the first character is "XZ", and the server obtains the media data of which the pinyin initial includes "XZ", for example, "pig peck", according to the "XZ" search.

And step S804, receiving the first media data and the at least one second character fed back by the server.

And after determining the first media data and the at least one second character, the server returns the first media data and the at least one second character to the television.

Step S805, displaying the first media data and displaying the recommended symbol at the at least one second character position.

The server sends the second character and at least one search result to the television, and the television can directly modify the virtual keyboard according to the second character and the at least one search result, namely, the recommendation symbol is displayed at the position corresponding to each second character on the virtual keyboard.

And step 806, receiving an input second control instruction.

After the television displays the recommended symbol and at least one search result, the user can further continue to input a second control instruction through the remote controller, wherein the second control instruction is used for representing that the first recommended symbol in the recommended symbol is selected.

Step S807, determining input of the target character at the position of the first recommended symbol corresponding to the second control instruction according to the received second control instruction.

Referring to fig. 4, if the first recommended symbol indicated by the second control command input by the user through the remote controller is "1", the television may determine that the target character is "Z".

Step S808, displaying the target character after searching for the first character in the text box.

After determining the target character, the tv may display the target character in the search text box, please continue to refer to fig. 4, for example, if the user inputs a character corresponding to the second control instruction as "Z" through the remote controller, the search text box displays the target character "Z".

Step S809, sending a search instruction containing the first character and the target character to the server to perform media data search.

Referring to fig. 4, if the first character is "X" and the target character is "Z", the tv generates a search command according to "XZ" and sends the search command to the server, so that the server searches for media data according to "XZ".
