The main interface of the display comprises a status bar (Top bar), a channel bar (Tab bar) and various recommended media assets or channels, and the like, the search control is often displayed in the status bar, the focus is on the current user interface, the starting point of the operation of the user remote controller, namely the currently selected position, is similar to the mouse hovering state of the PC end. In another implementation, the user presses a voice input key on the remote controller and sends out voice information of "opening a search function", and the controller can also control the display to jump to the search interface according to the voice control of the user.

In the embodiment of the present application, the controller 250 receives a selection operation on a virtual keyboard control in the search interface, and determines a target search term. In the search interface, according to the name of the medium resource to be searched, a user selects letters in the virtual keyboard control 601 through an upper key, a lower key, a left key and a right key on a remote controller, and a target search word is determined through the selected letters.

S520: and sending a search request containing the target search word to a server, wherein the server is used for feeding back search result data according to the target search word.

In the embodiment of the present application, after determining the target search term, the controller 250 sends a search request including the target search term to the server 300, so that the server can search for relevant search result data according to the target search request, and feeds back the search result data to the controller 250.

S530: and controlling the display to display a search result control according to the search result data.

After receiving the search result data fed back by the server 300, the controller 250 displays media titles associated with the target search term in the search result presentation area 603 according to the search result data, and presents a search result control corresponding to each media title in the search result preview area 604. For example, in fig. 6, after selecting the letter m in the virtual keyboard control 601, the user displays the names of the media assets beginning with the letter m in the search result display area, such as "stuffing for beauty", "album for beauty house dish", "beauty and beast", and so on, and correspondingly displays the search result controls corresponding to "stuffing for beauty", "album for beauty house dish", "beauty and beast" in the search result preview area 604.

S540: and receiving selection of a user on a first control in the search result control, and sending a media resource request containing a first identifier to the server, wherein the server is used for feeding back first media resource data to the controller according to the first identifier in the media resource request.

In the embodiment of the present application, the user browses the display contents in the search result display area 603 and the search result preview area 604, and finds the media assets that the user wants to search. After the user determines the assets the user wants to view, a corresponding first control can be selected from a plurality of controls in the search result controls in the search preview area. After receiving the selection of the first control by the user, the controller 250 sends a media asset request containing the first identifier to the server 300, and the server 300 feeds back the first media asset data to the controller 250 according to the first identifier in the media asset request. The first identifier may be a name of the asset corresponding to the first control selected by the user, or an Identity document (ID number) of the asset corresponding to the first control selected by the user, and the server 300 may search the first asset data from the database according to the first identifier and send the first asset data to the controller 250.

S550: and when the time interval from the last time of guidance prompt meets the trigger condition, displaying a playing interface according to the received first media asset data, and performing guidance prompt according to the guidance statement.

In this embodiment of the application, the guidance statement is generated according to the first identifier, for example, the guidance statement is determined according to a name of a medium corresponding to the first control. In one implementation, the controller 250 sends a media asset request including a first identifier to the server 300, and the server 300 may determine a name of a media asset corresponding to the first identifier according to the first identifier in the media asset request. Also, the server 300 stores a preset sentence template, for example, "the content can be searched the next time i say … …", "press the remote controller voice key … …, make the voice search more convenient", and so on. After determining the name of the medium resource, the server may nest the name of the medium resource in a preset statement template to generate a guidance statement. The server 300 simultaneously feeds back the guide sentence to the display apparatus 200 while feeding back the first asset data to the controller 250. In another implementation, when receiving a selection of a first control in the search result control by the user, the controller 250 may obtain a name of the asset corresponding to the first control. Moreover, a preset sentence template is stored in the display device 200, and after the name of the asset is determined, the controller 250 may nest the name of the asset in the preset sentence template, generate a guidance sentence, and store the guidance sentence in the display device 200.

In this embodiment of the application, the trigger condition may be set to a fixed preset duration, that is, meeting the trigger condition means: the time interval from the last guiding prompt is longer than the preset time. The controller 250 determines whether to perform the guidance display again according to the length of the time interval by detecting the time interval from the last guidance display. When the time interval from the last guidance prompt is longer than the preset time, the controller 250 displays a playing interface according to the received first media asset data, and performs guidance prompt according to the guidance statement. For example, the preset time period may be set to one week, and the controller 250 detects that the time interval from the last guidance prompt is more than one week, then the controller 250 controls the display 275 to display the playing interface and perform the guidance prompt. The guidance statement is generated according to the first identifier, for example, if the first identifier is a name of a asset corresponding to the first control, the guidance statement may include the name of the asset.

In some embodiments, the trigger condition may also be set to a preset duration that is not fixed, and at this time, meeting the trigger condition means: in the earlier stage of use of the display equipment, the time interval from the last time of guidance prompt is longer than a first preset time; and in the later use stage of the display equipment, the time interval from the last time of the guidance prompt is longer than a second preset time. When the display device 200 is just started to be used, the time interval from the last time of the guidance prompt is longer than a first preset time, or, in the later period of use of the display device 200, the time interval from the last time of the guidance prompt is longer than a second preset time, the controller 250 displays a playing interface according to the received first media asset data, and performs the guidance prompt according to the guidance statement. For example, the first preset time period may be set to be one week, and the second preset time period may be set to be half a month. In a half year after the display device 200 starts to be used, since a high frequency of guidance prompts for the user is required to prompt the user that the display device 200 has a voice search function, the controller 250 detects that the time interval from the previous guidance prompt is more than one week, and controls the display 275 to display a play interface and perform the guidance prompt. After the display device 200 is used for half a year, since the user knows that the display device 200 has the voice search function and may not be used to the voice search function, the controller 250 controls the display 275 to display the play interface and perform the guidance prompt when the time interval from the last guidance prompt is detected to be longer than half a month, so as to avoid that the frequency of the guidance prompt is too high, which brings discomfort to the user. It should be noted that, for the earlier stage and the later stage of the use of the display device, the first preset time length, the second preset time length, and the like may be set according to the use habits of most users on the display device, which is not limited herein.

In some embodiments, the first asset data includes an asset detail page corresponding to the asset selected by the user, and the controller 250 controls the play interface of the display to display the asset detail page. Referring to fig. 7, a diagram is presented of a media asset detail page provided in some embodiments of the present application. Referring to fig. 7, the media details page includes a video preview window, a details introduction of the media, a collection list of the media, and a full screen play control. When the asset detail page is displayed on the playing interface, after the user selects the full-screen playing control, the controller 250 controls the display 275 to play the asset in full screen.

In addition, for the display of the guide statement, a voice search guide control can be displayed in a floating layer above the playing interface, and the voice search guide control is used for loading and displaying the guide statement. Referring to fig. 7, the voice search guidance control comprises a small voice assistant 701 and a voice prompt box 702, the small voice assistant 701 can be set as a conspicuous cartoon animation, and a guidance sentence is loaded and displayed in the voice prompt box 702. Referring to fig. 6, if the user selects "american stuffing", the guidance sentence is set to "the content can be searched by" searching for american stuffing "the next time. Because what the display shows through the broadcast interface is the detailed page of media asset at this moment, does not play the audio frequency that the media asset corresponds, so in order to play better guide effect, this application accessible speaker pronunciation broadcast guide statement to reach the effect of the dual guide suggestion of characters pronunciation.

In other embodiments, the first asset data includes a media asset playing page corresponding to the user-selected media asset, and the controller 250 controls the playing interface of the display to display the media asset playing page. That is, when the time interval from the last guidance prompt is longer than the preset time, the controller 250 controls the play interface of the display 275 to directly play the corresponding media asset. Because the display displays the media asset playing page through the playing interface, the media asset playing is started at the moment, and then when the guiding prompt is carried out, the voice searching guiding control can be displayed only in the floating layer above the playing interface, namely, the voice small assistant and the voice prompt box play a role in guiding and prompting the user in characters.

When the guidance prompt is carried out in the application, the voice search guidance control is displayed in the floating layer above the playing interface, and/or the guidance sentence is played through the voice of the loudspeaker, namely the guidance prompt is carried out through characters and/or in a voice mode.

In the embodiment of the application, the display time of the voice search guide control can be controlled through the preset display time. The display time of the voice search guidance control can be configured in the server, for example, it can be set to 3S, that is, the floating layer for displaying the voice search guidance control can be hidden after displaying 3S, and the display 275 continues to play the user-selected media asset. Of course, when the display time is set to 0, the floating layer is not displayed.

In some embodiments, after sending the first media asset request to the server, the controller does not receive data related to the guidance statement fed back by the server after a preset timeout, and at this time, the display device may be considered to request that the guidance prompt is timed out, for example, if the display device does not receive the guidance statement within 5S, the display device may abandon the guidance prompt.

In some embodiments, the controller may actively request the server for the configuration of the preset display time and the preset timeout time after the display device is powered on. After the user opens the search interface, the controller requests the server for the relevant configuration of the voice guidance interface.

S560: and when the time interval from the last time of guidance prompt does not meet the trigger condition, displaying a playing interface according to the received first media asset data, and not performing guidance prompt.

In this embodiment of the present application, the trigger condition may be set to a fixed preset duration, that is, the trigger condition is not satisfied: the time interval from the last time of the guidance prompt is not more than the preset time. If the controller 250 detects that the time interval from the last guidance prompt is not longer than the preset time, in order to avoid too frequent guidance prompts to the user, the controller 250 only controls the display 275 to display the playing interface according to the received first media asset data, and does not perform guidance prompt. That is, the controller 250 controls only the display 275 to show a media detail page or a media play page.

In some embodiments, the trigger condition may also be set to a preset duration that is not fixed, and at this time, the trigger condition not being met refers to: in the earlier stage of use of the display equipment, the time interval from the last time of guidance prompt is not more than a first preset time; and in the later use stage of the display equipment, the time interval from the last time of the guidance prompt is not more than a second preset time. When the display device 200 is just started to be used, the time interval from the last time of the guidance prompt is not longer than the first preset time, or, in the later period of use of the display device 200, the time interval from the last time of the guidance prompt is not longer than the second preset time, the controller 250 displays the playing interface only according to the received first media asset data, and does not perform the guidance prompt.

In the above, the present application describes how to perform the guidance prompt, and next, the present application describes when to perform the guidance prompt and when not to perform the guidance prompt, that is, how to detect the time interval from the last time of performing the guidance prompt.

In the embodiment of the present application, the controller 250 determines the time interval of the last guidance prompt according to the time interval between the selection operation of the virtual keyboard control in the search interface this time and the selection operation of the virtual keyboard control in the search interface corresponding to the last guidance prompt display. The controller 250 may set a preset time period. In the search interface, a user searches for media assets by selecting the virtual keyboard control, that is, when the media assets are searched by using manual search, if the manual search operation is the first time within the preset time length, the controller 250 displays a play interface according to the received first media asset data, and performs guidance prompt according to the guidance statement. And, the controller 250 records the time of the current user's selection operation of the virtual keyboard control. When the user selects the virtual keyboard control in the search interface again, the controller 250 records a time interval between the time of the selection operation on the virtual keyboard control this time and the time of the selection operation on the virtual keyboard control corresponding to the previous guidance prompt, and determines the time interval from the previous guidance prompt according to the time interval.

For example, the controller 250 sets the preset time period to one week. If on Tuesday, the user searches for the media assets which the user wants to watch through the selection operation of the virtual keyboard control in the search interface, and the controller 250 controls the display 275 to display the play interface according to the selection operation of the user and performs guidance prompt. On saturday, the user searches for the media assets which the user wants to watch by selecting the virtual keyboard control, and since the time between saturday and tuesday is 5 days, and the time length is less than the preset time length, the controller 250 only controls the display 275 to display the playing interface, and does not perform guidance prompt. On wednesday in the second week, if the user searches for the media assets that the user wants to watch by using the selection operation of the virtual keyboard control, since the time of the wednesday is 9 days away from the wednesday, and the time is longer than the preset time, the controller 250 controls the display 275 to display the playing interface and perform guidance prompt.

In some embodiments, the controller 250 determines the time interval of the last guidance prompt according to the time interval between the current selection operation of the search control and the selection operation of the search control corresponding to the last guidance prompt display. The controller 250 may set a preset time period. After the user opens the display device 200, the user enters a search interface by selecting the search control, that is, the search function is opened, and if the operation of opening the search function is the first time within the preset time duration, the controller 250 displays a play interface according to the received first media data, and performs guidance prompt according to the guidance statement. And, the controller 250 records the time when the current user operates the search control. When the user selects the search control again, the controller 250 records a time interval between the time of the selection operation on the search control this time and the time of the selection operation on the search control corresponding to the previous guidance prompt, and determines the time interval of the previous guidance prompt according to the time interval.

For example, the controller 250 sets the preset time period to 10 days. If the user enters the search interface by selecting the search control on day 1, the controller 250 controls the display 275 to display the play interface according to the user's selection, and performs guidance prompt. On the 8 th day, the user enters the search interface by using the selection operation of the search control, and since the time interval from the 1 st day to the 8 th day is 5 days, which is less than the preset time length, the controller 250 only controls the display 275 to display the play interface, and does not perform guidance prompt. On day 12, if the user enters the search interface again by using the selection operation of the search control, since the time interval between day 1 and day 12 is 12 days, which is greater than the preset time length, the controller 250 controls the display 275 to display the play interface and perform guidance prompt.

In some embodiments, the controller 250 determines the time interval from the last time of the guidance prompt according to the time interval between the time of displaying the search interface this time and the time of displaying the search interface corresponding to the last guidance prompt. The controller 250 may set a preset time period. When the display device 200 jumps from the current display interface to the search interface, if the operation of entering the search interface is the first time within the preset time length, the controller 250 displays the play interface according to the received first media data, and performs guidance prompt according to the guidance statement. And, the controller 250 records the time when the search interface is currently displayed. When the display 275 displays the search interface again, the controller 250 records a time interval between a time when the search interface is displayed this time and a time when the search interface is displayed last time, and determines a time interval from which the guidance prompt was last performed at the time interval.

In some embodiments, the controller 250 determines the time interval from the last time of the guidance prompt according to the time interval between the selection operation of the control in the search result control this time and the selection operation of the control in the search result control corresponding to the last guidance prompt display. The controller 250 may set a preset time period. In the search interface, a user selects the media assets to be watched through the selection operation of the control in the search result control, and if the selection operation of the control in the search result control is the first time in the preset time length, the controller 250 displays the play interface according to the received first media asset data and conducts guidance prompt according to the guidance statement. And, the controller 250 records the time when the user selects the control in the search result control. When the user selects the control in the search result control again, the controller 250 records a time interval between the selection of the control in the search result control this time and the time when the selection of the control in the search result control corresponding to the guidance prompt was performed last time, and determines a time interval from the time interval when the guidance prompt was performed last time.

In some embodiments, the time interval from the last guidance prompt refers to: and the time interval between the time of receiving the operation instruction at this time and the time of receiving the operation instruction corresponding to the time of displaying the guidance prompt at the last time. When the user transmits an operation instruction to the display apparatus 200 through the remote controller, the controller 250 receives the operation instruction and records the time when the operation instruction is received. When the user sends the operation instruction again, the controller 250 records a time interval between the time of sending the operation instruction this time and the time of sending the operation instruction corresponding to the last guidance prompt, where the time interval is a time interval from the last guidance prompt.

In the method and the device, when the user uses the search function, the user is reminded of using the voice search periodically through the guidance prompt, so that the user is reminded of using the voice search function, and the number of times that the user uses the voice search is increased.

In order to further describe the guiding process of the voice search function, the embodiment of the application also provides a display device. The controller in the display device is configured to perform a guidance process for a voice search function and to present a voice search function guidance on the display. The configuration process of the controller will be described with reference to the drawings.

Referring to fig. 8, a flow chart of another guiding method for a voice search function according to some embodiments of the present application is shown. As shown in fig. 8, the guiding method includes the steps of:

The guide sentences can be used by the server to obtain the titles of popular search media assets in the current business search, wherein the number of the guide sentences can also be set by the server, and 3 guide sentences are selected in fig. 9. After the display apparatus 200 is turned on, when the user uses the search function for the first time, the user is informed how to use the voice search function by displaying the voice guidance floating layer on the search interface.

In some embodiments, after the user turns on the display device 200, the controller 250 may request the server 300 for the relevant configuration of the voice guidance floating layer.

In some embodiments, as long as the display 275 exhibits a search interface, that is, the controller 250 detects that the focus is within the search interface, the controller 250 controls the display 275 to exhibit a voice prompt control within the search interface. The voice prompt control includes: the prompt icon is arranged behind the search input frame, and different guide sentences are broadcast in turn at the position close to the prompt icon. Referring to fig. 10, a schematic diagram of a search interface including a voice prompt control shown on a display in some embodiments of the present application is shown. In fig. 10, a prompt icon is arranged beside the search input box, and the prompt icon can be set as a small voice assistant. And a guide statement is alternately broadcast beside the prompt icon. The guide sentence can be set as "try-me voice search", "speak me voice help", "speak" liudelhi movie "ready to search", "try-me" man-made stuffing ", and so on. The asset name in the voice guidance language may be a title of a popular search asset for the server 300 to obtain in the current service search. The server 300 may set the name of the asset in the guidance statement to be selected from the first name of the popular search asset to the fifteenth name of the popular search asset, and perform carousel following the guidance statement.

In some embodiments, controller 250 controls display 275 to display a voice prompt control in the search interface. The carousel time interval of the guide statement in the voice prompt control can be configured in the server, and for example, the carousel time interval can be set to 3S, that is, the guide statement is replaced every 3S.

In some embodiments, the controller 250 may actively request the server 300 for the relevant configuration of the leading sentence carousel time interval in the voice prompt control after the display device 200 is powered on. After the user opens the search interface, controller 250 requests the relevant configuration of the voice prompt control from server 300.

In the embodiment of the present application, if the focus is located on the prompt icon, the controller 250 may control the search interface to display the voice guidance floating layer shown in fig. 9.

As shown in connection with fig. 11, the server may include: the system comprises a terminal-oriented subsystem, a database, an operation background, a recommendation subsystem and a search subsystem. In order to implement the voice search function guidance before, during, and after the search, it is necessary to complete the configuration of the relevant settings related to the voice search function guidance in the server. Specifically, the staff can configure the preset display time and the preset timeout time in the voice search guidance control through the operation background, and also configure the carousel time interval of the guidance statement. In addition, a guide statement is also required to be configured through the operation background, and when the guide statement is configured, the operation background can set a recommendation rule of the guide statement and acquire popular search media resources in the current service search from the recommendation subsystem. And the operation background sends the configured time parameters and the guide statements to the database for storage. And then, after the user starts the display equipment, the display equipment can actively send a time parameter acquisition request to the terminal-oriented subsystem, and the terminal-oriented subsystem acquires the time parameter from the database according to the time parameter acquisition request and feeds the time parameter back to the display equipment. Then, after the user controls the display device to enter the search interface through the search instruction, the display device sends a guidance statement acquisition request to the terminal-oriented subsystem, and the terminal-oriented subsystem acquires the guidance statement from the database according to the guidance statement acquisition request. In the voice guidance floating layer, 3 guidance sentences can be randomly selected for display, and in order to ensure that the guidance sentences in the terminal-oriented subsystem are larger than the guidance sentences to be displayed in the display device, the terminal-oriented subsystem needs to judge whether the guidance sentences meet 3 guidance sentences, if the guidance sentences do not meet 3 data, the terminal-oriented subsystem can carry user characteristic messages to request the guidance sentences from the recommendation subsystem, and the recommendation subsystem feeds the guidance sentences back to the terminal-oriented subsystem. And organizing the acquired guide sentences facing the terminal subsystem, and feeding 3 guide sentences back to the display equipment. Before searching, if the display equipment is started, a user enters a search interface for the first time, the voice guide floating layer is displayed, and if the user does not enter the search interface for the first time, the voice guide floating layer is not displayed. In the searching process, as long as the user opens a searching interface, voice searching guidance is carried out through the voice prompt control. When a user searches, the display equipment sends a search media asset acquisition request through the terminal-oriented subsystem and the first search subsystem. And the searching subsystem feeds back corresponding media resources to the display equipment through the terminal-oriented subsystem, and in the searching process, if the time interval from the last time of guidance prompt is greater than the preset time within the preset time, guidance prompt is carried out according to the guidance statement.

Corresponding to the display device, an embodiment of the present application further provides a method for guiding a voice search function, where the method includes: the controller in the display device receives the operation instruction and determines the target search word. The controller sends a search request containing a target search word to the server, so that the server feeds back search result data according to the target search word and controls the display to display the search result control according to the search result data. The controller receives selection of a first control in the search result control by a user, and sends a media resource request containing a first identifier to the server, so that the server feeds back first media resource data to the controller according to the first identifier in the media resource request. And when the time interval from the last time of guidance prompt is greater than the preset time, displaying a playing interface according to the received first media asset data, and performing guidance prompt according to a guidance statement, wherein the guidance statement is generated according to the first identifier, and when the time interval from the last time of guidance prompt is not greater than the preset time, displaying the playing interface according to the received first media asset data without performing guidance prompt.

According to the method for guiding the voice search function, when the user uses the search function, in each periodic detection, as long as the user operation meets the trigger condition, the user can be prompted to use the voice search, so that the times of using the voice search by the user are increased, and the user is guided to use the voice search.

The embodiment of the application also provides another guiding method for the voice search function, and the method comprises the following steps: in the search interface, a controller in the display device receives a selection operation of a virtual keyboard control in the search interface and determines a target search word.
