Referring to fig. 8, the user selects the "close screen" option through the remote control, and the display device may be put into a speaker mode.

When entering the sound box mode, the display device judges whether the current service scene is a service non-breaking scene, if not, for example, if the current scene is a homepage or the television is playing video, the current service is broken through transition. Meanwhile, a cut scene page is started, countdown is started, and voice broadcasting is performed. And when the loudspeaker box needs to enter a loudspeaker box mode, a screen closing interface is called to close the screen. The service non-break scene generally refers to a music play class scene, and the remaining scenes may be service break scenes.

When the user makes the display device enter the sound box mode through the voice/sound box screen protection mode, the user can directly make the display device 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 through Hi music or a DMP screen closing mode, the media center (DMP) screen closing can listen to the song, and the scene is not interrupted for the service currently, so that the screen can be closed directly.

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

In some embodiments, when it is desired that the display device exit the speaker mode, an on-screen broadcast needs to be sent by the application that triggers the exit from the speaker mode (on-screen).

Fig. 9 illustrates a flow chart of a display device exiting a speaker 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, back key, home key, power key; a voice; pushing the bright screen; one touch instant broadcasting; video call, etc. After receiving the open screen broadcast, the loudspeaker box mode application judges whether the current scene is a business non-breaking scene; if the service is not interrupted, setting the current mode as a common television mode; if the service is interrupted, a transition broadcast needs to be sent, a network television mode is pulled up, and a network television homepage is displayed. And sending a broadcast notice to each application, calling a screen opening interface to control the screen opening of the display when the sound box mode is currently exited.

In some embodiments, the display is in a closed state when the display device enters the speaker mode; if the normal television function of the display device is to be used again, the display device needs to exit the sound box mode, and the display is controlled to be in a screen-on state. The display device is only different in the state of the switch screen of the display when entering the sound box mode or exiting the sound box mode, and other states are the same, for example, the host is always in an operating state, and can normally respond to control instructions and the like.

In general, when the display device performs transition, the display is directly turned off, and the background performs signal source switching. However, the display device enters the sound box mode and is similar to the shutdown state of the display device, so that the display is in a screen-closing state in terms of visual effect. In this scenario, the user may easily perform an error 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 a 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 user may misuse the display device as an abnormality due to failing to exit the speaker mode, so that the display is not turned on.

Therefore, in order to avoid that a user mistakenly thinks that the display device enters the sound box mode is powered off and generates misoperation on the display device entering the sound box mode, the embodiment of the invention provides the display device which is configured to execute the display method of the prompt information in the sound box mode, so that the display device can prompt the user in time when entering the sound box mode, so as to inform the user that the current state of the display device enters the sound box mode instead of being powered off, prompt the user to open a screen in real time and exit the sound box mode, and prevent the display device from influencing the user experience without responding to misoperation of the user.

When the display equipment enters a sound box mode, prompt information is presented in a display, wherein the prompt information comprises a cut scene and a broadcast sound corpus. The prompt information can inform the user of the current state of the display device, and can prompt the user of the current operation flow of the display device used as the intelligent sound box, so that the user can accurately operate the display device, and the user experience is improved.

FIG. 10 illustrates a flow chart of a method of presenting hints in a speaker mode in accordance with some embodiments; FIG. 11 illustrates a data flow diagram of a method of presenting hints information in a speaker mode in accordance with some embodiments. An embodiment of the present invention provides a display apparatus including: a display configured to present a user interface; the controller is connected with the display, and when executing the method for displaying the prompt information in the sound box mode shown in fig. 10 and 11, the controller is configured to execute the following steps:

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

When a 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 screen closing condition can be triggered by triggering the screen closing condition, wherein the triggered screen closing condition comprises the modes of Power key, voice, speaker screen saver, hi music/DMP screen closing and the like shown in FIG. 7. The user performs the operation of triggering the screen closing condition by any mode to generate a corresponding instruction.

In order to inform the user in time that the display device is about to enter the sound box mode and prompt the user how to operate the flow of 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 receiving a control instruction for controlling the local end of the display device to enter the sound box mode, the controller needs to switch signal sources in the background of the display device, and meanwhile obtains a cutscene and a broadcast corpus for prompting a user to operate the display device in the sound box mode. The cutscene is a randomly displayed background picture that is used to introduce steps of how to operate the display device using voice commands in a sound box mode. The broadcast corpus is used for informing the user of the state of the current display device from the auditory sense and prompting the user to operate the display device in a voice mode.

The display of the cutscene has timeliness, and the broadcasting of the broadcasting sound corpus also has timeliness, so that the display and the broadcasting are performed in a countdown mode when the display equipment displays the cutscene and plays the broadcasting sound corpus. Under the scene, based on the cutscene and the broadcast voice corpus, starting a cutscene countdown, wherein the cutscene countdown refers to the duration of displaying prompt information for a user and is displayed in a countdown mode.

Fig. 12 illustrates a method flow diagram for obtaining cutscene according to some embodiments. Referring to process (1) in fig. 12, in acquiring the cutscene, the display device needs to randomly acquire a background picture to generate the cutscene. Specifically, the controller, when executing the acquisition cutscene, is further configured to execute the following steps:

and 111, acquiring a background picture path for realizing the cutscene.

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

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

When the cut scene is obtained, the cut scene randomly displays a background picture, and the background pictures displayed in two adjacent times are different. In order to avoid network abnormality and other reasons, the background picture cannot be timely obtained by the local terminal, so that timely display of the cut scene is affected, and the background picture can be stored in a background picture path in advance.

For example, the display device may utilize the background picture read when the process of obtaining the cutscene is executed last time when the cutscene is obtained this time, and the background picture read this time may be used when the process of obtaining the cutscene is executed next time.

The background picture path storing the background picture acquired in the previous time can be stored locally, and if the background picture is stored in the background picture path, the background picture path is not empty when the background picture is read when the scene cut animation acquisition process is executed in the previous time. At this time, the background picture can be directly loaded based on the background picture path, and finally, the cut scene is generated based on the background picture.

If the background picture path does not store the background picture, the background picture path is empty when the background picture is not read when the process of acquiring the cut scene is executed last time.

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

step 114, if the background picture path is empty, an advertisement path for realizing the cutscene is acquired.

Step 115, if the advertisement path is not empty, loading the advertisement and generating a cutscene based on the advertisement.

And 116, if the advertisement path is empty, loading a local default picture, and generating a cutscene based on the local default picture.

When the background picture path is empty, the background picture is not read when the process of acquiring the cut scene is executed last time, and at this time, an interface for displaying advertisement business can be replaced in order to ensure the normal display of the cut scene. Thus, an advertisement path for implementing the cutscene may be acquired.

If the display device is preconfigured with the advertisement service, the advertisement path is stored locally and is not empty, and at this time, the advertisement can be directly loaded based on the advertisement path so as to generate the cut scene 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 this time, in order to facilitate timely display of the cutscene, a local default picture can be loaded. 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, in generating the cutscene, in addition to background pictures, advertising services, some social applications with higher heat at the current time period, such as AI fitness, heart rate health research, etc., may be presented. The scene cut animation displayed by the display device when entering the sound box mode can promote user experience (prompt the operation flow of various display devices in the sound box mode), can also display richer content, recommend more interesting content to the user, and has better user experience.

In some embodiments, if the cloud animation data is obtained from the server in real time when the current process of obtaining the cutscene is executed, the data obtaining speed is slow, if the network abnormality exists, the cutscene cannot be generated, so that the display device cannot display prompt information in time when entering the sound box mode, and user experience is affected.

Therefore, in order to ensure that the display device can timely display the cut scene when entering the sound box 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 scene currently), that is, acquire cloud animation data from the cloud of the server, and the real-time acquired cloud animation data is the background picture required when the cut scene process is executed next time. The two processes are synchronously carried out without mutual interference.

In some embodiments, the cloud animation data requested by the display device from the server side 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 can be directly read when the next execution of the process of obtaining the cutscene is convenient, and the cutscene is timely generated. Therefore, the execution process of the display device for obtaining 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 process (2) in fig. 12, the controller is further configured to perform the following steps when performing step 111, i.e. acquiring a background picture path for implementing a cutscene:

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

Step 1112, when the local system network is in a connection state, acquiring a current time stamp of the current request cloud animation data and a historical time stamp of the last request cloud animation data.

Step 1113, if the current time stamp is inconsistent with the historical time stamp, deleting the background picture in the local buffer path, and storing the background picture in the cloud animation data of the current request into the local buffer path, wherein the local buffer path is the background picture path required by next acquisition of the cut scene.

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

The display device synchronously executes the process (2) in fig. 12, that is, starts a service process (service) for requesting data from the server, while executing the process (1) in fig. 12, to randomly store the background picture path required by the process (1) in fig. 12.

When the display equipment end requests data from the server, the local end needs to be ensured to keep a network connection state, and different connection states execute different processes of storing the background picture paths. Therefore, after the service is started, it is first determined whether the local system network is in a connected state.

When the local system network is in a connection state, the display device can send a data request to the server in real time so as to acquire cloud animation data. Therefore, when the local system network is in a connection state, the local end of the display device requests the cloud interface in real time, a data request is sent to the cloud interface of the server, and the server sends the cloud animation data to the display device after receiving the data request.

After receiving the cloud animation data, the display equipment analyzes the cloud animation data to obtain the current 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 time stamp will change. When the time stamp changes, then 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. The local folder for storing the background picture is a local cache path (les/tvbox).

In some embodiments, if the current timestamp is inconsistent with the historical timestamp, it indicates that the background picture stored in the cloud has been updated by the system background, and at this time, the background picture in the local buffer path (les/tvbox) needs to be deleted, and the deletion is to delete all the background pictures in the local buffer path (les/tvbox).

After the deleting operation is executed, the local cache path is empty, then the background picture in the cloud animation data of the current request is stored in the local cache path, and updating of the background picture in the local cache path is achieved, so that the local cache path is used as a background picture path required when the cut animation is acquired 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 of the current request can 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 a historical background picture before storing the new background picture. To avoid repeated storage of the same background picture, it is detected whether the new background picture has been stored.

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

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

102, if the background picture in the cloud animation data of the current request is already stored, not storing the background picture in a local cache path;

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

When the current time stamp is consistent with the historical time stamp, the display device can store a new background picture in cloud animation data which is requested from the server in real time into a local cache path (les/tvbox). Because the history background picture may be stored in the local buffer 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 buffer 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 at this time is not stored in the local cache path. 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 at this time needs to be saved in the local cache path.

Therefore, when the local system network is in a connection state, the display device can request cloud animation data from the server in real time, and after analysis, the background picture is updated by comparing the current time stamp with the historical time stamp. When the comparison is inconsistent (update exists), deleting the locally cached background picture, and downloading again, namely storing the 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 in the local cache path. When in storage, if the new background picture is already 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 store the background picture path required by the process (1) in fig. 12, so that the background picture path is convenient to use when the process of acquiring the cut scene 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 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 a background picture path used when the process of acquiring the cut scene is executed next time.

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

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

Step 1116, if the background picture is already displayed, re-randomly acquiring the background picture in the local buffer path.

Step 1117, if the background picture is not displayed, determining a local buffer path where the background picture is located as a background picture path required when the cut scene is acquired next time.

When the local system network is not in a connection state, in order to ensure that a new background picture can be acquired to save a new background picture path, a background picture can be randomly selected in the local cache path.

In order to avoid that when the display equipment enters a sound box mode, the cut-off animation displayed in the display device in two adjacent times is the same, and the randomly selected background picture is required to be inconsistent with the background picture displayed in the last time. Therefore, after a background picture is randomly acquired, it is required to determine whether the background picture has been displayed last time.

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

If the randomly acquired background picture is not displayed last time, the local cache path of the background picture can be determined to be the background picture path required when the cut scene is acquired next time, so that updating of the background picture path is realized, and different background pictures can be displayed when the cut scene acquisition process is executed next time.

Fig. 13 illustrates an effect diagram of a cutscene according to some embodiments. Referring to the four cutscene shown in fig. 13, each cutscene is generated with a different background picture. When the display equipment enters a sound box mode, the display can randomly display any one of the cutscenes, and the cutscenes displayed in two adjacent times are different.

Therefore, when the local system network is not in a connection state, the device local end can randomly acquire 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 process of acquiring the cut scene are different when two adjacent execution processes are performed; 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 a background picture path to update the background picture path required when the next execution of the process of obtaining the cut scene is performed, so that the cut scene displayed in two adjacent times is prevented from being identical.

In some embodiments, after receiving an instruction for controlling the local end of the display device to enter the sound box mode, the display device can synchronously acquire a cut scene and a broadcast sound corpus of the display device operated by the display device in the sound box mode, so that when the cut scene is displayed in the display based on cut countdown, the device can synchronously broadcast in a voice mode, a flow for prompting the user how to operate the display device entering the sound box mode from the visual and auditory angles is realized, and user experience is improved. Therefore, when the display device executes the process of acquiring the cutscene provided in the foregoing embodiment, the process of acquiring the broadcast corpus may also be executed simultaneously.

Fig. 14 illustrates a flow chart of a method of acquiring a corpus of broadcast sounds and a cutfield countdown in accordance with some embodiments. In some embodiments, referring to process (1) in fig. 14, the controller is further configured to perform the following steps when performing step S1, i.e. obtaining the broadcast corpus:

step 121, acquiring a broadcast cache for storing broadcast voice corpus.

And 122, if the broadcast buffer is not empty, acquiring the broadcast corpus stored in the broadcast buffer.

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

The required broadcast voice corpus in the sound box mode can be configured by a system background, and different broadcast voices can be configured in display devices of different models. The method comprises the steps that a broadcast voice corpus is strongly related to the stop countdown, namely, the duration of the stop countdown is positively related to the text length of the broadcast voice corpus.

In order to avoid network abnormality and other reasons, the local terminal cannot acquire the broadcast voice corpus in time, so that the timely display of the broadcast voice corpus is affected, and information such as the broadcast voice corpus can be stored locally in advance. When the broadcast voice corpus is acquired, the display equipment is locally used for storing the broadcast cache of which the position is local.

Therefore, when the broadcasting voice corpus needs to be acquired, the local broadcasting cache can be read. If the broadcast corpus is stored in the broadcast cache, the broadcast cache is not empty when the related data is read when the process of acquiring the broadcast corpus is executed last time. At this time, the broadcast corpus stored in the broadcast buffer can be directly read.

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

In some embodiments, if cloud broadcast data is obtained from a server in real time when the current process of obtaining the broadcast corpus is executed, the data obtaining speed is slow, if a network abnormality exists, the broadcast corpus cannot be displayed in time, so that prompt information cannot be displayed in time in a display device when the display device enters a sound box mode, and user experience is affected.

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

In some embodiments, the cloud broadcasting data requested by the display device from the server side in real time includes broadcasting corpus, and the broadcasting corpus is stored in a local broadcasting buffer, so that the broadcasting corpus under the broadcasting buffer can be directly read when the next execution of the process of obtaining the broadcasting corpus is convenient, and the broadcasting corpus can be timely played. Therefore, the executing process of the display device for obtaining the broadcasting buffer memory this time is equivalent to the process of requesting the cloud broadcasting data from the server in real time to store the cloud broadcasting data in the broadcasting buffer memory.

Specifically, referring to process (2) in fig. 14, in executing step 121, that is, obtaining a broadcast buffer for storing a broadcast corpus, the controller is further configured to execute the following steps:

step 1211, when the local system network is in a connection state, acquiring cloud broadcast data from a server.

And 1212, analyzing cloud broadcasting data to obtain broadcasting voice corpus, and storing the broadcasting voice corpus into a broadcasting cache.

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

When the display equipment end requests data from the server, the local end needs to be ensured to keep a network connection state, and if the local system network is not in the connection state, the cloud broadcasting data is not requested.

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

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

In some embodiments, the controller, upon performing the starting of the cutback countdown corresponding to the cutscene and the broadcast corpus, is further configured to perform the steps of:

step 1213, obtaining a transition consumption time required by the display device during transition and a text word number corresponding to the broadcasted corpus, wherein the transition refers to a process of switching the signal source when the display device enters the sound box mode.

Step 1214, calculating the broadcasting time consumption needed when broadcasting the broadcasting voice corpus based on the text word number and the word time consumption of the broadcasting voice corpus.

And 1215, calculating the total time length of the transition time length and the broadcasting time length, and determining the transition countdown.

When the display equipment enters the sound box mode, transition is needed, namely switching of signal sources is realized, so that the display is closed. When the system is in transition, the sound of the system is muted, and if the corpus of the broadcast sound is played, the system has no sound, so that the system cannot be successfully broadcast. Therefore, in order to ensure the normal playing of the broadcast voice corpus, the voice broadcast needs to be performed after the display equipment is successfully switched.

The display device starts to switch, and the off countdown is started to count, so that the off countdown is the sum of the switching time consumption and the broadcasting time consumption. And the broadcasting time consumption is related to the text word number corresponding to the broadcasting voice corpus, and the broadcasting voice corpora with different text lengths correspond to different broadcasting time consumption.

In some embodiments, the duration of the cutback countdown is the presentation duration of the cutscene.

In some embodiments, the transition time period (timeilo) required for the display device to transition to the venue is typically within 3 seconds. It takes 405ms to set one "word" per broadcast, i.e., the word average time length (timeTts) is 405ms. If the text word number of the broadcast voice corpus is N, the required broadcast time consumption time length for broadcasting the broadcast voice corpus is N times Tts. At this time, total time=timeilo+n×timetts, in ms.

In some embodiments, the cutfield countdown is based on an upward integer. At this time, the duration of the cutback countdown=math.ceil (total time/1000), in s.

For example, when the display device is controlled to enter a sound box mode, the current transition time is 2s, the text word number of the broadcasted sound corpus is 8 words, and then the total time total time=2s+8×405ms=2s+3240ms=5s240 ms. Finally, the duration of the cutback countdown=math.ceil (5.240) =6s is determined.

Therefore, the countdown of the departure is configured to be 6s to meet the broadcasting requirement, namely when the time length of the countdown of the departure is determined, the transition time length and the broadcasting time length are fully considered, and the principle of broadcasting is carried out after the transition of the display equipment is successful, so that after the countdown of the departure is finished, the corpus of the broadcasting voice can be ensured to be completely played. After the broadcasting sound is played, the display is closed, so that the display equipment enters a sound box mode.

S2, after the start of the stop-count-down, displaying the stop-count-down animation in a display, and calling an audio output interface to play the broadcast corpus.

After a control instruction for controlling the display equipment to enter a sound box mode is received, the local end of the display equipment acquires information such as a cut scene, a broadcast voice corpus, cut scene countdown and the like required for displaying prompt information. And the local end of the display equipment responds to the control instruction, starts to count the field countdown, and simultaneously displays the field animation in the display. The cut scene comprises information such as an operation schematic scene graph, an operation text and the like for operating the display equipment in the sound box mode.

In order to facilitate the user to know the operation flow 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 the operation experience.

In some embodiments, to ensure that the broadcast corpus is able to be completely played, the controller, after executing the step-down timer, displays the step-down animation in the display, and invokes the audio output interface to play the broadcast corpus, is further configured to:

and 21, when the countdown of the cut is started, generating a cut prompting interface based on the cut animation and the countdown control of the cut, and displaying the cut prompting interface in a display, wherein the countdown control of the cut refers to a control generated based on the countdown of the cut.

Step 22, in the process of countdown of the transition, if the broadcast generated after the transition of the display equipment is received, calling the audio output interface to start playing the broadcast corpus.

When the display equipment transitions when entering the sound box mode, prompt information is displayed for a user, and countdown can be synchronously displayed. At the moment, when the countdown of the cut is started, the cut countdown control is synchronously generated according to the countdown of the cut, and then the cut prompting interface is generated according to the cut animation and the countdown control so as to display the cut prompting interface in a display.

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

In some embodiments, the duration corresponding to the cutfield countdown control is sequentially reduced according to the lapse of system time, and in the visual effect, the time displayed in the cutfield prompt interface is gradually reduced in a countdown form.

After the countdown of the transition begins, the background of the display device is transitioned, so that the display device can play the broadcast corpus in time after the transition of the display device is successful, and the display device can send successful broadcast after the transition is successful.

In the process of countdown of the transition, if the broadcast generated after the transition of the local end of the display equipment is received, the audio output interface is called to start playing the broadcast corpus, and at the moment, the time of receiving the broadcast is the initial playing time of the broadcast corpus.

In some embodiments, the audio output interface comprises: a local default broadcast interface and a TTS broadcast interface.

And a TTS broadcasting interface is arranged in the display equipment so as to realize automatic broadcasting of the broadcasting voice corpus. TTS (Text To Speech) is a broadcasting device with a built-in Speech chip, and the TTS Speech broadcasting device can receive various Text information issued by the controller and read in an automatic Speech mode.

The TTS function needs to rely on the network, so that when the broadcast corpus is played, whether the local system network is in a connection state needs to be detected first, so that the target broadcast interface is accurately called to play the broadcast corpus.

In some embodiments, when the display device plays the broadcast corpus, different interfaces can be called according to the network state of the local system to realize playing.

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

The default broadcasting interface is an audio preset broadcasting interface, and at the moment, the broadcasting sound corpus played by the audio preset broadcasting interface is a fixed audio file, and is not obtained from the broadcasting cache. The fixed audio file may also be a broadcast corpus obtained from a local default cache.

Therefore, when the display equipment is controlled to enter the sound box mode, prompt information can be displayed in the display. During display, displaying the cut scene and the cut countdown at the initial moment; after the display equipment is successfully transferred, the broadcasting of the broadcasting sound corpus is started, so that the broadcasting sound corpus can be completely played.
