When a user triggers a Power key, a Power-off selection interface is started, and options such as 'screen off', 'Power off', 'restart', 'art gallery' and the like are displayed in the Power-off selection interface. Referring to fig. 8, the user may enter the display device into a speaker mode by selecting the "off screen" option via the remote control.

When the speaker mode is entered, the display device determines whether the current service scene is a scene in which the service is not interrupted, and if not, for example, if the current scene is a homepage or a video is being played by a television, the current service is interrupted by transition. And simultaneously, starting a scene crossing animation page, starting countdown and carrying out voice broadcasting. When the loudspeaker box mode needs to be entered, the screen turning-off interface is called to turn off the screen. The non-service interruption scene generally refers to a music playing class scene, and the rest of the scenes can be service interruption scenes.

And when the user enables the display equipment to enter the sound box mode through the voice/sound box screen protection mode, the user can directly enable the display equipment to enter the sound box mode through the voice mode without depending on the steps. If the user controls the display device to enter the sound box mode in a Hi music or DMP screen off mode, the Hi music is turned off to listen to the songs, the media center (DMP) is turned off to listen to the songs, and the current service is a scene without interruption, so that the screen can be directly turned off.

After the display equipment is turned off, the screen turning-off attribute can be synchronously set, namely, the system attribute value is set to be 1, and the mode of the sound box is indicated to be entered; and setting the system attribute value to 0, indicating that the loudspeaker box mode is not entered and the loudspeaker box is in the screen-opening state. When judging whether transition is needed, the method is determined according to the current service scene, and if the current service scene is a scene with uninterrupted service, the transition is not needed, and the screen is directly turned off; and if the current service scene is a service interruption scene, transition is needed, and the screen is turned off after transition is completed. The transition operation refers to an action of switching a signal source, such as cutting off played video.

In some embodiments, when the display device is required to exit the speaker mode, an open screen broadcast needs to be sent by the application that triggers the exit of the speaker mode (open screen).

FIG. 9 illustrates a flow diagram for a display device exiting an audio box mode according to some embodiments. Referring to fig. 9, applications that trigger exit from speaker mode (open screen) include, but are not limited to, infrared voice, return key, home key, Power key; voice; pushing the bright screen; one-touch instant sowing; video calls, etc. After receiving the open screen broadcast, the sound box mode application judges whether the current scene is a scene with no service interruption; if the service is not interrupted, setting the current mode as a common television mode; if the scene is interrupted by the service, transition broadcast needs to be sent, the network television mode is pulled up, and the network television homepage is displayed. And sending a broadcast notification to each application, exiting the sound box mode at present, calling a screen opening interface, and controlling the display to open the screen.

In some embodiments, the display is in the off-screen state when the display device enters the speaker mode; and if the common television function of the display equipment is to be used again, the display equipment is required to exit the sound box mode, and the display is controlled to be in the screen-opening state. The difference between the display device entering the speaker mode and exiting the speaker mode is that the states of the switch panel of the display are different, and the rest states are the same, for example, the host is always in a running state, and can normally respond to a control instruction, and the like.

In general, when a display device performs a transition, a display is directly turned off, and a background executes signal source switching. However, the state of the display device entering the speaker mode is similar to the state of the display device being turned off, and the display is in the off-screen state in terms of visual effect. In this scenario, a user is very likely to perform a wrong operation on the display device, for example, if the user wants to use the display device, the user may perform a corresponding power-on operation in a power-off state, but the current display device is in the speaker mode, and performing the power-on operation on the display device in the speaker mode may cause the display device to fail to respond or respond, but the display device is not turned on due to failing to exit the speaker mode, so that the user mistakenly regards that the display device is abnormal.

Therefore, in order to avoid that a user mistakenly considers a display device entering a speaker mode as being powered off and misoperation is caused on the display device entering the speaker mode, the embodiment of the invention provides the display device configured to execute the method for displaying the prompt information in the speaker mode, so that the display device can prompt the user in time when entering the speaker mode to inform the user that the current state of the display device is the speaker mode instead of being powered off, and prompt the user to turn on a screen in real time to exit the speaker mode, thereby preventing the display device from not responding to the misoperation of the user and influencing user experience.

When the display equipment enters a sound box mode, prompt information is presented in a display, and the prompt information comprises a cut-in animation and broadcast sound linguistic data. The prompt information can inform the user of the current state of the display equipment and also can prompt the user of the operation process of using the current display equipment as the intelligent sound box, so that the user can accurately operate the display equipment, and the user experience is improved.

FIG. 10 illustrates a flow diagram of a method for presenting a reminder in speaker mode, according to some embodiments; fig. 11 illustrates a data flow diagram of a method of presenting a reminder in speaker mode, in accordance with some embodiments. An embodiment of the present invention provides a display device, including: a display configured to present a user interface; a controller connected to the display, wherein when the method for presenting the prompt message in the speaker mode shown in fig. 10 and 11 is executed, the controller is configured to execute the following steps:

s1, responding to a control instruction for entering the sound box mode received through the user interface, acquiring the cut-in animation and the broadcast voice corpus for prompting that the display device operated by the user is in the sound box mode, and starting the cut-in countdown corresponding to the cut-in animation and the broadcast voice corpus, wherein the sound box mode is a mode that a controller of the display device is in a running state and a display is in a screen closing state.

When the user uses the display device, a corresponding screen is presented in the display. If the user needs to control the display device to enter the speaker mode, the user can trigger the screen-off condition, where the triggered screen-off condition includes the Power key, voice, speaker screen saver, Hi music/DMP screen-off mode shown in fig. 7. And the user executes the operation of triggering the screen closing condition in any mode and generates a corresponding instruction.

In order to facilitate timely informing a user that the display device is about to enter a sound box mode and prompt the user how to operate the display device in the sound box mode, prompt information can be presented in the display when the display device enters the sound box mode.

Therefore, after the controller receives a control instruction for controlling the local terminal of the display device to enter the sound box mode, the background of the display device needs to switch signal sources, and meanwhile, the controller obtains the cut-in animation and the broadcast sound corpus for prompting the display device operated by the user to be in the sound box mode. The cut-through animation is a randomly displayed background picture which is used for introducing steps of how to operate the display device by using voice instructions in the loudspeaker box mode. The broadcast voice corpus is used for informing a user of the current state of the display device from the perspective of hearing and prompting the user to operate the display device in a voice mode.

The showing of the cut scene animation has timeliness, and the broadcasting of the broadcast sound linguistic data also has timeliness, so that the display device needs to show and broadcast the cut scene animation and the broadcast sound linguistic data in a countdown mode when displaying the cut scene animation and broadcasting the broadcast sound linguistic data. In this scenario, based on the cut scene animation and the broadcast phonetic corpus, a cut scene countdown is started, which is a time length for displaying the prompt information for the user and is displayed in a countdown mode.

FIG. 12 illustrates a flow diagram of a method of obtaining cut scenes, according to some embodiments. Referring to process (1) in fig. 12, when acquiring a cut scene, the display device needs to randomly acquire a background picture to generate the cut scene. Specifically, the controller is further configured to perform the following steps in executing the obtaining of the cut scene:

and step 111, obtaining a background picture path for realizing the cut scene animation.

And 112, if the background picture path is not empty, loading the background picture based on the background picture path.

And step 113, generating the cut scene animation based on the background picture.

When the cut-scene animation is obtained, the cut-scene animation randomly shows a background picture, and the background pictures shown twice are different. In order to avoid the reason that the local terminal cannot acquire the background picture in time due to network abnormality and the like, the timely display of the cut-in animation is influenced, and the background picture can be stored in the background picture path in advance.

For example, the display device may use the background picture read when the process of acquiring the cut scene is performed last time when the cut scene is acquired this time, and the background picture read this time may be used when the process of acquiring the cut scene is performed next time.

The background picture path storing the previously acquired background picture can be stored locally, and if the background picture is stored in the background picture path, which indicates that the background picture is read when the process of acquiring the cut-scene animation is executed last time, the background picture path is not empty. At this time, the background picture can be loaded directly based on the background picture path, and finally, the cut scene animation is generated based on the background picture.

If the background picture is not stored in the background picture path, the background picture path is empty when the background picture is not read in the previous process of acquiring the cut-scene animation.

In some embodiments, when the background picture path is empty, the controller is further configured to:

and step 114, if the background picture path is empty, acquiring an advertisement path for realizing the cut scene animation.

And step 115, if the advertisement path is not empty, loading the advertisement and generating a scene cut animation based on the advertisement.

And step 116, if the advertisement path is empty, loading a local default picture, and generating the cut scene animation based on the local default picture.

When the background picture path is empty, the background picture is not read when the process of obtaining the cut scene animation is executed last time, and at the moment, the interface for displaying the advertisement service can be replaced for ensuring the normal display of the cut scene animation. Thus, an advertisement path for realizing a cut scene can be acquired.

If the display device is configured with the advertisement service in advance, the advertisement path is stored locally, and the advertisement path is not empty, and at the moment, the advertisement can be directly loaded based on the advertisement path so as to generate the cut-in animation based on the advertisement.

If the display device is not configured with the advertisement service in advance, the advertisement path stored locally is empty, and at the moment, a local default picture can be loaded so as to facilitate the timely display of the cut-through animation. The local default picture may be stored in a local cache path to generate a cutscene based on the local default picture.

In some embodiments, when generating the cut scene, in addition to the background picture and the advertisement service, some social applications with high popularity in the current period, such as AI fitness, heart rate health research, etc., can be displayed. The cut-through animation displayed when the display device enters the loudspeaker box mode can not only improve the user experience (prompt the user to operate various display devices in the loudspeaker box mode), but also display richer contents, recommend more interesting contents to the user, and achieve better user experience.

In some embodiments, if the cloud animation data is acquired from the server in real time when the current process of acquiring the cut-field animation is executed, the data acquisition speed is slow, and if a network anomaly exists, the cut-field animation cannot be generated, so that prompt information cannot be displayed in a display in time when the display device enters a sound box mode, and user experience is affected.

Therefore, in order to ensure that the display device can display the cut-in animation in time when entering the speaker mode, the display device can store the required background picture locally in advance, that is, the display device can execute another process while acquiring the background picture from the local (executing the process of acquiring the cut-in animation at the current time), that is, acquire the cloud animation data from the cloud of the server, and the cloud animation data acquired in real time is the background picture required when the process of acquiring the cut-in animation is executed next time. The two processes are carried out synchronously without mutual interference.

In some embodiments, cloud animation data requested by the display device to the server in real time includes a background picture, and the background picture is stored in a local background picture path, so that the background picture in the path is directly read when a process of acquiring the cut-scene animation is executed next time, and the cut-scene animation is generated in time. Therefore, the execution process of the display device for acquiring the background picture path at this time is equivalent to the process of requesting the cloud animation data from the server in real time to store the cloud animation data in the background picture path.

Specifically, referring to the process (2) in fig. 12, in the step 111 of acquiring the background picture path for implementing the cut scene, the controller is further configured to perform the following steps:

step 1111, detecting whether the local system network is in a connection state.

Step 1112, when the local system network is in a connected state, obtaining a current timestamp of the current request cloud animation data and a historical timestamp of the last request cloud animation data.

And 1113, if the current timestamp is not consistent with the historical timestamp, deleting the background picture in the local cache path, and storing the background picture in the cloud animation data requested this time into the local cache path, where the local cache path is a background picture path required for obtaining the cut-in animation next time.

Step 1114, if the current timestamp is consistent with the historical timestamp, storing the background picture in the cloud animation data of the current request into the local cache path.

The display apparatus simultaneously executes the process (1) of fig. 12 and synchronously executes the process (2) of fig. 12, i.e., starts a service process (service) that requests data from the server, to randomly store the background picture path required by the process (1) of fig. 12.

When a display device side requests data from a server, the local side needs to be ensured to keep a network connection state, and different processes for storing background picture paths are executed in different connection states. Therefore, after the service is started, whether the local system network is in a connection state is judged.

When the local system network is in a connection state, the display device can send a data request to the server in real time to acquire cloud animation data. Therefore, when the local system network is in a connection state, the local terminal of the display device requests the cloud interface in real time, sends the data request to the cloud interface of the server, and the server receives the data request and then sends the cloud animation data to the display device.

After receiving the cloud animation data, the display device analyzes the cloud animation data to obtain the time stamp and the background picture.

In some embodiments, if the background picture is not updated by the system background, the timestamp does not change; if the background picture is updated by the system background, the timestamp will change. When the timestamp changes, the locally stored background picture needs to be updated. Therefore, the display device obtains the historical timestamp corresponding to the last request cloud animation data, and compares the historical timestamp with the current timestamp. Wherein, the folder for storing the background picture is a local cache path (les/tvbox).

In some embodiments, if the current timestamp is not consistent with the historical timestamp, it is indicated that the background picture stored in the cloud is updated by the system background, at this time, the background picture in the local cache path (les/tvbox) needs to be deleted, where the deletion is to delete all the background pictures in the local cache path (les/tvbox).

And after the deleting operation is executed, the local cache path is empty, and then the background picture in the cloud animation data of the request is stored in the local cache path, so that the background picture in the local cache path is updated, and the local cache path is used as the background picture path required for acquiring the scene-crossing animation next time.

In some embodiments, if the current timestamp is consistent with the historical timestamp, which indicates that the background picture stored in the cloud is not updated by the system background, the background picture in the cloud animation data requested this time may be directly stored in the local cache path.

In some embodiments, when the local cache path stores the background picture, if the local cache path does not perform a delete operation, the local cache path has stored the historical background picture before storing the new background picture. To avoid repeated storage of the same background picture, it is necessary to detect whether the new background picture has already been stored.

Specifically, the controller is further configured to perform the following steps when executing the storing of the background picture in the cloud animation data of the request to the local cache path:

step 101, detecting whether a background picture in the cloud animation data of the request is stored in a local cache path.

Step 102, if the background picture in the cloud animation data requested this time is stored, not storing the background picture in the cloud animation data requested this time to a local cache path;

and 103, if the background picture in the cloud data of the request is not stored, storing the background picture in the cloud data of the request to a local cache path.

When the current timestamp is consistent with the historical timestamp, the display device may store a new background picture in the cloud animation data requested from the server in real time to a local cache path (les/tvbox). Since the historical background picture may be stored in the local cache path at this time, before storing a new background picture, it is determined whether the newly acquired background picture is already stored in the local cache path.

If the new background picture is already stored, that is, the background picture already exists in the local cache path, in order to avoid repeated storage, the new background picture requested this time is not stored in the local cache path any more. If the new background picture is not stored, that is, the background picture does not exist in the local cache path, the new background picture requested this time needs to be stored in the local cache path.

Therefore, when the local system network is in a connection state, the display device can request the cloud animation data from the server in real time, and after analysis, the current timestamp is compared with the historical timestamp to judge whether the background picture is updated or not by the system background. When the comparison is inconsistent (there is update), deleting the background picture of the local cache, and downloading again, namely storing a new background picture in the newly acquired cloud animation data into a local cache path; if the comparison is consistent (not updated), the new background picture is directly stored into the local cache path. During storage, if the new background picture is stored, the new background picture is not stored; if the new background picture is not stored, it needs to be stored. The scheme can ensure that the display equipment can acquire the background picture in real time, and stores the background picture path required by the process (1) in the figure 12, so that the display equipment is convenient to use when the process of acquiring the cut scene animation is executed next time.

In some embodiments, the display device cannot request data from the server in real-time if the local system network is not in a connected state. At this time, any one background picture can be randomly selected from the local cache path as a new background picture, and the access path of the new background picture is used as the background picture path used when the process of acquiring the cut scene animation is executed next time.

In some embodiments, when the local system network is not in the connected state, the controller is further configured to:

and 1115, when the local system network is not in a connected state, randomly acquiring the background picture in the local cache path.

Step 1116, if the background picture is already displayed, the background picture in the local cache path is randomly acquired again.

Step 1117, if the background picture is not shown, determining the local cache path where the background picture is located as the background picture path required for next obtaining the cut scene animation.

When the local system network is not in a connected state, in order to ensure that a new background picture can be acquired so as to store a new background picture path, a background picture can be randomly selected from the local cache path.

In order to avoid that the two adjacent showing transition animations in the display are the same when the display device enters the sound box mode, the randomly selected background picture is required to be inconsistent with the last showing background picture. Therefore, after a background picture is randomly acquired, it is necessary to determine whether the background picture has been displayed last time.

If the background picture has been displayed last time, another background picture needs to be obtained again in the local cache path, and the process is circulated in sequence until the next randomly obtained background picture is not displayed last time.

If the randomly acquired background picture is not displayed last time, the local cache path where the background picture is located can be determined as the background picture path required by the next scene cut animation acquisition, so that the background picture path is updated, and different background pictures can be displayed when the scene cut animation acquisition process is executed next time.

FIG. 13 illustrates a diagram of the effects of a cut scene according to some embodiments. Referring to the four sets of cutscenes shown in FIG. 13, each cutscene is generated using a different background picture. When the display equipment enters the sound box mode, the display can randomly show any one set of cut scene animation, and the cut scene animation shown in two adjacent times is different.

Therefore, when the local system network is not in a connection state, the local terminal of the equipment can randomly obtain a background picture in the local cache path in order to update the background picture path in time so as to ensure that the background pictures required by the two adjacent processes for obtaining the cut-scene animation are different; if the background picture is displayed last time, randomly selecting again; if the background picture is not displayed last time, the path of the background picture is used as the background picture path to update the background picture path required by the next process of obtaining the cut scene animation, so that the cut scene animations displayed in two adjacent times are prevented from being identical.

In some embodiments, after receiving an instruction for controlling the local terminal of the display device to enter the speaker mode, the display device may synchronously acquire a cut-in animation and a broadcast speech corpus for prompting a user, where the display device operated by the display device is in the speaker mode, so that when the cut-in animation is displayed in the display based on cut-in countdown, the device may synchronously broadcast in a speech manner, thereby realizing a process for prompting the user how to operate the display device entering the speaker mode from a visual and auditory perspective, and improving user experience. Therefore, when the display device executes the process of acquiring the cut scene provided by the foregoing embodiment, the process of acquiring the broadcast phonetic corpus may also be executed at the same time.

FIG. 14 illustrates a flow diagram of a method of obtaining broadcast phonetic corpus and cut-off countdown, according to some embodiments. In some embodiments, referring to process (1) in fig. 14, in step S1, the controller obtains the find phonetic corpus, and is further configured to perform the following steps:

and step 121, obtaining a broadcast cache for storing broadcast voice corpora.

And step 122, if the broadcast cache is not empty, acquiring broadcast voice corpora stored in the broadcast cache.

And step 123, if the broadcast cache is empty, acquiring the broadcast voice corpus stored in the local default cache.

The required broadcast voice corpora under the loudspeaker box mode can be configured by the system background, and different broadcast voices can be configured in display devices of different models. The broadcast sound corpus is strongly related to the cross-fielding countdown, namely the time length of the cross-fielding countdown is positively related to the text length of the broadcast sound corpus.

In order to avoid reasons such as network abnormity and the like, the local terminal cannot acquire the broadcast voice corpora in time, timely display of the broadcast voice corpora is influenced, and information such as the broadcast voice corpora can be stored locally in advance. When the broadcast voice corpus is acquired, the position of the display device, which is locally used for storing the broadcast voice corpus, is a local broadcast cache.

Therefore, when the broadcast voice corpus needs to be acquired, the local broadcast cache can be read. If the broadcast voice corpora are stored in the broadcast cache, the relevant data are read when the process of acquiring the broadcast voice corpora is executed for the previous time, and then the broadcast cache is not empty. At this time, the broadcast voice corpus stored in the broadcast cache can be directly read.

If the broadcast voice corpus is not stored in the broadcast cache, the broadcast cache is empty when the related data is not read when the process of obtaining the broadcast voice corpus is executed for the previous time. At this time, in order to ensure normal and timely display of the broadcast voice corpus, the broadcast voice corpus stored in the local default cache can be acquired.

In some embodiments, if the cloud broadcast data is acquired from the server in real time when the current broadcast voice corpus acquiring process is executed, the data acquiring speed is slow, and if network abnormality exists, the broadcast voice corpus cannot be displayed in time, so that the display device cannot display prompt information in time when entering a speaker mode, and user experience is affected.

Therefore, in order to ensure that the display device can timely display the broadcast voice corpus when entering the speaker mode, the display device can store the required broadcast voice corpus locally in advance, namely, the display device can execute another process while acquiring the broadcast voice corpus locally (executing the current acquisition of the broadcast voice corpus process), namely, the cloud broadcast data is acquired from the server cloud, and the real-time acquired cloud broadcast data is required data when the broadcast voice corpus process is acquired next time. The two processes are carried out synchronously without mutual interference.

In some embodiments, the display device broadcasts the data including the broadcast speech material to the cloud end requested by the server end in real time, stores the broadcast speech material in the local broadcast cache, and is convenient for directly reading the broadcast speech material in the broadcast cache when the next execution of the process of acquiring the broadcast speech material is performed, so as to broadcast the broadcast speech material in time. Therefore, the execution process of the display device obtaining the broadcast cache at this time is equivalent to the process of requesting the cloud broadcast data from the server in real time to be stored in the broadcast cache.

Specifically, referring to the process (2) in fig. 14, in step 121, the controller obtains a broadcast buffer for storing broadcast speech, and is further configured to perform the following steps:

and step 1211, when the local system network is in a connected state, obtaining the cloud broadcast data from the server.

And step 1212, analyzing the cloud broadcast data to obtain broadcast voice corpora, and storing the broadcast voice corpora to a broadcast cache.

While executing the process (1) in fig. 14, the display device synchronously executes the process (2) in fig. 14, that is, starts a cloud interface that requests data from the server, so as to store the broadcast cache required by the process (1) in fig. 14.

When the display device side requests data from the server, the local side needs to be guaranteed to keep a network connection state, and if the local system network is not in the connection state, the cloud side is not requested to broadcast the data.

And if the local system network is in a connection state, acquiring cloud broadcasting data from the server. And after receiving the data request, the server transmits the cloud broadcast data to the display equipment. After the display device receives the cloud broadcast data, the cloud broadcast data are analyzed to obtain broadcast voice corpora, and finally the broadcast voice corpora obtained in real time are stored in a local broadcast cache so as to be directly read when the display device is controlled to enter a loudspeaker box mode next time to acquire the broadcast voice corpora progress, the processing efficiency is improved, and the user experience is good.

In some embodiments, since the broadcast corpus is strongly correlated with the time-of-flight countdown, the time-of-flight countdown may be determined based on the broadcast corpus to ensure that a synchronization mechanism between the broadcast corpus and the time-of-flight countdown is obtained to ensure that the broadcast time of the broadcast corpus matches the time-of-flight countdown.

In some embodiments, the controller, in performing the initiating of the cut-through countdown corresponding to the cut-through animation and the announced phonetic corpus, is further configured to perform the steps of:

step 1213, obtaining a transition consumption time and a text word number corresponding to the broadcast voice corpus required by the display device during transition, where the transition is a process of switching a signal source when the display device enters a speaker mode.

Step 1214, calculating the broadcast consumption duration required when broadcasting the broadcast speech corpus based on the number of the text words and the average word consumption duration of the broadcast speech corpus.

And step 1215, calculating the total time of transition consumption time and broadcast consumption time, and determining the transition countdown.

When the display equipment enters the loudspeaker box mode, transition is needed, namely, switching of a signal source is achieved, and the display is turned off. The sound of system will be muted when the transition, if broadcast the broadcast of sound corpus this moment, then can not have sound, lead to failing to report. Therefore, in order to ensure the normal playing of the broadcast speech material, the speech broadcast needs to be performed after the transition of the display device is successful.

Since the counting of the transition countdown is started when the display device starts to perform the transition, the counting of the transition countdown is the sum of the transition consumption time and the broadcast consumption time. The broadcast time consumption is related to the number of text words corresponding to the broadcast voice corpora, and the broadcast voice corpora with different text lengths correspond to different broadcast time consumption.

In some embodiments, the time duration of the cut-through countdown is the presentation time duration of the cut-through animation.

In some embodiments, the transition consumption time (timessilo) required for a display device transition is typically within 3 s. It takes 405ms for each broadcast of a "word", i.e., the time duration of each word (timeTts) is set to 405 ms. If the number of text words of the broadcast voice corpus is N, the broadcast consumption time required for playing the broadcast voice corpus is N × timeTts. At this time, the total time duration totalTime is timessimilo + N timeTts in units of ms.

In some embodiments, the field-crossing countdown is based on taking an integer upward. At this time, the time duration timecount down of the field countdown is math.ceil (totalTime/1000), and is expressed in s.

For example, when the display device is controlled to enter the speaker mode, if it is acquired that the current transition consumption time is 2s and the number of text words of the spoken corpus is 8 words, the total time totalTime is 2s +8 × 405ms is 2s +3240ms is 5s240 ms. Finally, the time duration timecount down of the field crossing countdown is determined to be math.ceil (5.240) 6 s.

It is thus clear that the configuration of counting down the time of passing a scene into 6s accords with the requirement of reporting, when confirming the time length of counting down the time of passing a scene promptly, fully consider to change and consume time length and report and consume time length to report the principle after display device changes the success again, can make and finish the back at the count down of passing a scene, guarantee to report the sound corpus and can completely broadcast. After the broadcast sound is played, the display is turned off, and the display equipment enters a sound box mode.

And S2, displaying the cut scene animation in the display after the cut scene countdown is started, and calling the audio output interface to play the broadcast voice corpus.

After receiving a control instruction for controlling the display device to enter the loudspeaker box mode, the display device local end obtains information such as cut-scene animation, broadcast voice corpora, cut-scene countdown and the like required for displaying prompt information. And the local terminal of the display equipment responds to the control instruction, starts to count the time of the field crossing countdown, and simultaneously displays the field crossing animation in the display. The cut-scene animation comprises information such as an operation schematic scene graph and an operation pattern of the display device in the loudspeaker box mode.

In order to enable a user to know the operation process in real time, the broadcast voice corpus can be synchronously played after the transition is successful, so that the broadcast voice corpus can be completely played, and the user can know complete prompt information to improve operation experience.

In some embodiments, to ensure that the broadcast speech corpus can be completely played, the controller displays the cut scene animation in the display after the execution starts at the cut scene countdown, and calls the audio output interface to play the broadcast speech corpus, and the controller is further configured to:

and step 21, when the passing countdown is started, generating a passing prompt interface based on the passing animation and a passing countdown control, and displaying the interface in a display, wherein the passing countdown control is generated based on the passing countdown.

And step 22, in the process of counting down when the scene passes, if the broadcast generated after the transition of the display equipment is finished is received, calling an audio output interface to start playing the broadcast voice corpus.

When the display device is switched to the sound box mode, prompt information is displayed for a user, and countdown can be synchronously displayed. And at the moment, when the field crossing countdown starts to count down, synchronously generating a field crossing countdown control according to the field crossing countdown, and then generating a field crossing prompt interface according to the field crossing animation and the field crossing countdown control so as to display the field crossing prompt interface in a display.

The cut scene prompt interface can be as shown in any one of the effect diagrams in fig. 13, and the cut scene countdown control is displayed on the upper layer of the cut scene and is positioned on one side of the cut scene, so that the information in the cut scene is prevented from being shielded.

In some embodiments, the time duration corresponding to the cut-in countdown control decreases sequentially according to the lapse of the system time, and the time displayed in the cut-in prompt interface gradually decreases in a countdown mode in visual effect.

And after the transition countdown is started, the background of the display equipment performs transition, and in order to ensure that the display equipment can play the broadcast speech material in time after the transition is successful, the display equipment can send a successful broadcast after the transition is successful.

In the process of counting down in the field, if the broadcast generated after the transition of the local terminal of the display equipment is received, the audio output interface is called to start playing the broadcast voice corpus, and at the moment, the time of receiving the broadcast is the initial playing time of the broadcast voice corpus.

In some embodiments, the audio output interface comprises: and locally defaulting a broadcast interface and a TTS broadcast interface.

A TTS (text to speech) broadcast interface is arranged in the display device to realize automatic broadcast of broadcast voice corpora. TTS (Text To Speech, from Text To Speech) is a broadcast device with a built-in Speech chip, and a TTS Speech broadcaster can receive various types of Text information sent by a controller and read aloud in an automatic Speech mode.

The TTS function needs to depend on the network, and therefore, when playing the broadcast speech corpus, it needs to detect whether the local system network is in a connected state first, so as to accurately call the target broadcast interface to realize the playing of the broadcast speech corpus.

In some embodiments, when the display device plays the broadcast speech material, different interfaces may be invoked to implement the playing according to the local system network status.

When the local system network is in a connection state, the TTS broadcast interface can be directly called to play the broadcast voice corpora, and automatic playing is realized. If the local system network is not in a connection state, the TTS broadcast interface cannot be called, and in order to realize the timely broadcast of the broadcast voice corpora, the local default broadcast interface can be called instead to play the broadcast voice corpora.

The default broadcast interface is an audio preset broadcast interface, and at the moment, the broadcast voice corpora played by the audio preset broadcast interface are fixed audio files instead of the broadcast voice corpora obtained from the broadcast cache. The fixed audio file can also be broadcast voice corpora obtained from a local default cache.

Therefore, when the display equipment is controlled to enter the loudspeaker box mode, prompt information can be displayed in the display. During displaying, displaying the cut-in animation and the cut-in countdown at the initial moment; and after the transition of the display equipment is successful, the broadcast speech material is played, so that the broadcast speech material can be completely played. At the moment, the user can synchronously know that the current display equipment is about to enter the loudspeaker box mode with the visual angle and the auditory angle, and obtains the process of operating the display equipment in the loudspeaker box mode, so that the user experience is good.

And S3, after the process countdown is finished, canceling the display of the process animation, stopping playing the broadcast voice corpus, and switching the use state of the display to a screen off state so as to enable the display equipment to enter a sound box mode.

After the prompt information in the display is displayed, the display equipment can be controlled to enter a sound box mode. At this moment, namely after the field-crossing countdown is finished, the display of the field-crossing animation is cancelled in the display, the display equipment cancels the calling of the audio output interface so as to stop playing the broadcast voice corpus, and switches the use state of the display into the off-screen state, the display is in a black screen state, and the host continues to operate.

Because the time length of the transition countdown is more than or equal to the total time length of the transition consumption time length and the broadcasting consumption time length, the broadcasting voice corpus can be completely played before the display is turned off, and the user experience is good.

Therefore, when the display device is about to enter the speaker mode, the display device provided by the embodiment of the invention can synchronously display the prompt information in the display to inform the user that the current state of the display device is the speaker mode instead of the power-off state, and prompt the user to turn on the screen in real time to exit the speaker mode, so that the display device is prevented from not responding to the misoperation of the user and influencing the user experience.

s2, after the cut-in countdown is started, displaying the cut-in animation in a display, and calling an audio output interface to play the broadcast voice corpus;

and S3, after the cross-scene countdown is finished, canceling the display of the cross-scene animation, stopping playing the broadcast voice corpus, and switching the use state of the display to be a screen-off state so that the display equipment enters a sound box mode.
