Specifically, the display unit may be used to implement display of a screen; the processor is mainly used for responding to various operations triggered by the user based on the interactive flat panel (including management mode selection operation, picture-in-picture playing function triggering operation, channel determination operation, channel selection operation, focus operation and the like), so as to determine a target channel and the like; the playing unit is mainly used for playing the audio of the target channel selected by the processor. As shown in fig. 5, the interactive tablet may also include a memory 504, a wireless unit 505, an input unit 506, a sensor 507, and a power module 508. It should be noted that, the specific architecture and functions of each component of the interactive tablet will be described in detail below, and will not be described herein.

The connection line may be other data connection lines such as HDMI line.

The external device 102 may be a notebook computer or the like for providing video data.

In the scenario provided in this embodiment of the present application, when the interactive flat board 101 receives the first video data of the first channel, the display unit 501 displays the first video data through the first picture, when the user starts the picture-in-picture playing function based on the interactive flat board 101, the processor 502 generates at least one second picture by responding to the triggering operation call of the user and overlapping the first picture through the user interface application programming interface, meanwhile, the user connects the external device 102 with the interactive flat board 101 through the connecting line, at this time, the external device 102 can send the second video data to the interactive flat board 101 through the input unit 506 of the interactive flat board 101, the channel of the external device 102 connected to the interactive flat board 101 is the second channel, and when the interactive flat board 101 receives the second video data of the second channel, the display unit 501 immediately displays the second video data through the second picture overlapped on the first picture, thereby achieving the purpose of simultaneously displaying the first channel of the picture-in-picture playing function and the video data of the second channel; in order to implement management of the audio of the first channel and the second channel, the user triggers a management mode selection operation through the interactive tablet 101, the processor 502 responds to the operation, determines a target audio management mode (including a single channel mode, a focus mode and a mixing mode) corresponding to the operation, obtains preset management conditions of the target audio management mode, selects a target channel from the first channel and the second channel according to the preset management conditions, and finally plays the audio of the target channel through the playing unit 503 of the interactive tablet 101.

In the audio management process, on the premise that the user operates the interactive flat panel to start the picture-in-picture playing function, the user automatically selects a proper target audio management mode by operating the interactive flat panel according to different use scenes, so that a processor of the interactive flat panel determines a corresponding target audio management mode according to management mode selection operation, wherein the target audio management mode comprises a single channel mode, a focus mode and a sound mixing mode, the variety of the current audio management mode is enriched, the interactive flat panel is not limited to a certain single audio management mode under the picture-in-picture playing function, meanwhile, the processor manages the audio of each channel according to preset management conditions of the target audio management mode, different audio management strategies are realized, and the audio playing effect under the picture-in-picture playing function is improved.

It should be noted that, the picture-in-picture playing function described above refers to a video content presentation mode. The method is characterized in that one video is played in full screen, and the other video is played in a small area of a picture at the same time, so that the method is widely used for interactive flat-panel, television, video recording, monitoring and the like. Picture-in-Picture (PIP) technology uses a manner of overlapping two video pictures, one larger and one smaller, to simultaneously present two video signals. The first channel may be called a main channel, may be a channel Zhuo Tongdao where the interactive tablet is located, and the second channel may be called a sub-channel, and may be called a picture-in-picture channel, for example, an HDMI channel connected to an external device; accordingly, the first video data may be video data derived from an interactive tablet android channel, and the second video data may be video data derived from an external device (e.g., video player, monitoring camera, notebook, game console, etc.); the first picture may be a full screen picture when played out full screen, i.e. a main picture under the picture-in-picture play function, and the second picture may be a smaller picture superimposed on the full screen picture, i.e. a sub-picture under the picture-in-picture play function.

In the embodiment of the application, the audio channels include a main audio channel and a sub audio channel under the function of picture-in-picture playing. The main audio channel is a corresponding audio channel when the main playing screen plays audio and video; the sub-audio channel, i.e. the picture-in-picture audio channel, is the corresponding audio channel when the sub-play screen plays the audio and video. For example, when the playing terminal starts a picture-in-picture (PIP) playing function in an android channel, and selects the PIP channel as an HDMI channel, the android channel is a main audio channel in the scene, and the HDMI channel is a sub audio channel in the scene.

In this embodiment of the present application, the management mode selection operation may be triggered by a user through voice, gestures, or the like, or may be triggered by a user through a mode selection control (including a button of a remote controller, a touch control of a touch screen, or the like) that triggers an actual control unit of the interactive tablet.

In the embodiment of the application, the user can select a desired management mode as a target audio management mode through a management mode selection operation of the interactive tablet. The audio management modes mainly include three types, wherein: the single channel mode refers to a management mode of selecting a single channel through channel selection operation or preset channel priority, and then outputting the audio of the single channel only; the focus mode refers to a management mode that a user triggers a focus operation through an interactive tablet, selects a corresponding focus picture from a first picture and at least one second picture, and then outputs audio of a channel corresponding to the focus picture; the mixing mode refers to a management mode of mixing audio of a first channel and at least one second channel being played.

In this embodiment of the present application, the preset management condition refers to a processing policy of audio data buffering of the first channel and at least one second channel in the target audio management mode.

It should be noted that, the schematic view of the scenario shown in fig. 1 is only an example, and the apparatus and scenario described in the embodiments of the present application are for more clearly describing the technical solutions of the embodiments of the present application, and do not constitute a limitation on the technical solutions provided in the embodiments of the present application, and those skilled in the art can know that, with the evolution of the system and the appearance of a new service scenario, the technical solutions provided in the embodiments of the present application are equally applicable to similar technical problems. The following will describe in detail. The following description of the embodiments is not intended to limit the preferred embodiments.

In view of the foregoing scenario of the audio management method, the audio management method in the embodiment of the present application will be described in detail, and referring to fig. 2, fig. 2 is a schematic flow chart of the audio management method provided in the embodiment of the present application. The method at least comprises the following steps:

s201: first video data of a first channel is received and displayed through a first picture.

When a user views a video through the interactive tablet, clicking a corresponding video source to receive video data of a channel corresponding to the video source, wherein the channel corresponding to the video source can be called a first channel, and the video data can be called a first video data. Then, the display unit of the interactive flat panel displays the first video data in a first screen for viewing by a user.

S202: and displaying the second video data through at least one second picture superimposed on the first picture when the second video data of the at least one second channel is received.

In this application embodiment, aim at solving interactive flat work under the picture-in-picture instant music play function, audio management mode is single, the not good problem of audio play effect. Therefore, when the user turns on the picture-in-picture playing function, the interactive tablet needs to superimpose the second picture on the current first picture to display the video data from the second channel, which comprises the following specific steps: responding to the triggering operation of the picture-in-picture playing function, calling and generating at least one second picture by overlapping on the first picture through a user interface application programming interface; receiving second video data of at least one second channel corresponding to the channel determining operation in response to the channel determining operation; and displaying the second video data through the second picture. The operation of triggering the pip playing function may be that a user triggers a pip playing function key in the interactive tablet, or that the user sends out a voice/gesture instruction for starting the pip playing function, etc.; the picture-in-picture playing function refers to displaying at least two sets of programs on the same screen by utilizing a digital technology, namely, inserting one or more compressed sub-pictures on a main picture which is normally watched, wherein the main picture which is normally watched is a first picture in the embodiment of the application, and the compressed sub-picture is a second picture in the embodiment of the application.

Specifically, taking the first channel as an android channel and the second channel as an HDMI channel as an example. When a user views video data corresponding to a first picture (main picture), a picture-in-picture (PIP) playing function is triggered by an interactive flat panel, at this time, a processor of the interactive flat panel responds to the operation, invokes and generates at least one second picture (sub-picture) by overlapping on the first picture (main picture) through a user interface application programming interface, as shown in fig. 3, fig. 3 is an interface schematic diagram under the picture-in-picture playing function provided by the embodiment of the application, wherein a playing screen a is the first picture (main picture), a playing screen B is the second picture (sub-picture), then, the user connects an external device with the interactive flat panel through an HDMI connection line, and sends a channel determining operation through the interactive flat panel, thereby selecting the second channel as an HDMI channel, the external device sends the second video data to an input unit of the interactive flat panel through the HDMI connection line, and after receiving the second video data from the HDMI channel, the input unit of the interactive flat panel displays the corresponding second video data in the generated second picture (sub-picture) overlapped on the first picture (main picture), so as to realize the purpose of simultaneously displaying the corresponding second video data and the sub-picture.

In one embodiment, the position of the first screen or the second screen is not fixed, and it can move according to the operation of the user, and the specific steps include: receiving a picture position moving operation; the position of the first screen or the second screen is adjusted according to the screen position moving operation. The screen position moving operation may include a first screen position moving operation for adjusting a position of the first screen and a second screen position moving operation for adjusting a position of the second screen.

Specifically, the screen position moving operation may determine whether to adjust the position of the first screen or the second screen according to the position of the mouse. Specifically, when the user operates the mouse to move within the first screen range, the screen position moving operation can adjust the position of the first screen according to the movement of the mouse; when the user operates the mouse to move within the second screen range, the screen position moving operation may adjust the position of the second screen according to the movement of the mouse. By adjusting the position of the first screen or the second screen, it is possible to avoid the effect that the first screen and the second screen overlap partially to affect the viewing effect of the lower display screen of interest to the user.

S203: responding to the management mode selection operation, and determining a target audio management mode corresponding to the management mode selection operation; the target audio management mode comprises a single channel mode, a focus mode and a mixing mode.

Through the above operation, at this time, the first picture (main picture) and the second picture (sub picture) are both playing video data of the corresponding channel, if both pictures are playing audio of the corresponding channel, the first channel plays audio of the android channel according to the android audio decoding process, and the second channel plays audio of the HDMI channel according to the HDMI audio decoding process. According to the scheme in the prior art, the processor directly mixes the audio of the two channels and plays the audio through the playing unit, so that the audio playing effect is poor.

Therefore, the embodiments of the present application propose a plurality of management modes that can be selected by the user, so that the user can select a suitable target audio management mode according to different usage scenarios, and the method is not limited to a single audio management mode. Specifically, the interactive tablet responds to a management mode selection operation sent by a user so as to determine a corresponding target audio management mode, wherein the management mode selection operation can be triggered by the user through operations such as voice and gestures, and can also be triggered by the user through a mode selection control (including a button of a remote controller, a touch control of a touch screen and the like) for triggering an actual control unit.

The audio management mode mainly comprises a single-channel mode, a focus mode and a mixing mode. The single channel mode refers to a management mode of selecting a single channel through channel selection operation or preset channel priority, and then outputting the audio of the single channel only; the focus mode refers to a management mode that a user triggers a focus operation through an interactive tablet, selects a corresponding focus picture from a first picture and at least one second picture, and then outputs audio of a channel corresponding to the focus picture; the mixing mode refers to a management mode of mixing audio of a first channel and at least one second channel being played.

Specifically, the user can make the interactive tablet manage the audio of each channel under the picture-in-picture function according to the audio management mode selected by the user by sending out the management mode selection operation. For example, the user may send a voice/gesture/touch operation to turn on the single channel mode, and the interactive pad may determine that the target audio management mode is the single channel mode in response to the operation; for another example, the user may issue a voice/gesture/touch operation to "turn on focus mode", and the processor of the interactive pad may determine that the target audio management mode is focus mode, etc., in response to the operation.

It should be noted that, after the user selects the single channel mode, a target channel is selected from the channels to realize the audio management of the single channel; similarly, after the user selects the focus mode, the interactive tablet also needs to determine a corresponding focus picture according to the focus operation of the user, so as to determine a target channel corresponding to the focus picture and realize audio management of the target channel.

S204: and acquiring and selecting a target channel from the first channel and at least one second channel according to preset management conditions of the target audio management mode, and playing the audio of the target channel.

As shown in fig. 4, fig. 4 is a schematic diagram of a relationship between an audio management mode and a preset management condition thereof according to an embodiment of the present application. As can be seen from fig. 4, the preset management conditions in the single-channel mode and the focus mode are the same, and are all the audio outside the mute target channel, so as to obtain and play the audio of the target channel, and the preset management condition in the audio mixing mode is to output the mixed audio of each channel.

In one embodiment, the target audio management mode includes a single channel mode, in which a user can directly determine a target audio channel through a channel selection operation, and further manage audio of each channel according to a preset management condition, and the specific steps include: acquiring preset management conditions of a target audio management mode; receiving a channel selection operation in a single channel mode; selecting a target channel from the first channel and the at least one second channel according to the channel selection operation; and according to preset management conditions, muting the audio outside the target channel, and acquiring and playing the audio of the target channel. The channel selection operation may be that the user clicks a specific audio channel key, or that the user selects a specific audio channel through voice/gesture operation.

After the user selects the single channel mode as the target audio management mode, the user also needs to select a target channel from the channels under the current pip playing function. Taking the first channel as an android channel and the second channel as an HDMI channel as an example, if a user selects the android channel as a target channel through channel selection operation, the processor performs mute processing on the audio of the HDMI channel according to a preset management condition in a single channel mode, acquires the audio of the android channel, and plays the audio through a play unit.

In one embodiment, the target audio management mode includes a single channel mode, in which the target channel can be automatically determined according to a priority of an audio channel preset by a user, and then the audio of each channel is managed according to a preset management condition, and the specific steps include: acquiring preset management conditions and preset channel priorities of a target audio management mode; selecting a target channel from the first channel and at least one second channel according to a preset channel priority; and according to preset management conditions, muting the audio outside the target channel, and acquiring and playing the audio of the target channel. The preset priority of the audio channel may be set by default when the interactive tablet leaves the factory, for example, the priority of the first channel is highest; or may be customized by the user according to actual usage habits.

Specifically, taking the highest priority of the first channel as an example, taking the first channel with high priority as a target channel according to the order of the priority, and finally, according to a preset management condition, muting the audio of the second channel to acquire and play the audio of the first channel.

It should be noted that, the single channel mode can play the audio of the corresponding channel according to the requirement of the user, so as to improve the audio playing effect in the picture-in-picture playing mode.

In one embodiment, the target audio management mode further includes a focus mode, and the interactive tablet may determine a target channel according to a focus operation of a user in the focus mode, and further manage audio of each channel according to a preset management condition, where the specific steps include: acquiring preset management conditions of a target audio management mode; receiving a focus operation in a focus mode; selecting a target channel from the first channel and the at least one second channel according to the focal operation; and according to preset management conditions, muting the audio outside the target channel, and acquiring and playing the audio of the target channel. The focus operation refers to which screen is clicked/touched by the user, which screen is the current focus interface, and the channel corresponding to the focus interface is the target channel.

Specifically, the specific steps of the user sending out a focus operation through the current playing picture of the interactive flat board, and the interactive flat board responding to the focus operation to determine the target channel include: determining a target picture in the first picture and the at least one second picture according to the focus operation; and determining a target channel from the first channel and the at least one second channel according to the target picture. If the user operates the focus to the second picture (i.e., the sub-picture) under the picture-in-picture playing function, that is, the processor takes the second picture as the target picture, and traces the video data source of the second picture to the second channel (e.g., the HDMI channel), thereby determining that the second channel (e.g., the HDMI channel) is the target channel, finally, according to the preset management condition, muting the audio of the first channel (e.g., the android channel), obtaining the audio of the second channel (e.g., the HDMI channel), and playing the audio through the playing unit of the interactive tablet. Similarly, if the user operates the focus to the first picture (i.e., the main picture), that is, the processor takes the first picture as the target picture, and traces the source of the video data of the first picture as the first channel (e.g., the android channel), thereby determining that the first channel (e.g., the android channel) is the target channel, and finally, according to the preset management condition, muting the audio of the second channel (i.e., the HDMI channel), obtaining the audio of the first channel (e.g., the android channel), and playing the audio through the playing unit of the interactive tablet. The focus mode can intelligently judge the watching focus of the user according to the focus operation of the user, so that the audio of the corresponding channel is played, the user operation is simplified, and the user experience sense and the audio playing effect are improved.

In addition, if the user selects the audio mixing mode as the target management mode, the audio of any channel is not required to be processed, the audio of each channel is directly mixed, and the mixed audio is output through the playing unit.

In one embodiment, the core of the corresponding preset management condition is to output only the audio of the designated channel, i.e. the audio outside the mute target channel, to acquire and play the audio of the target channel, whether in the single channel mode or the focus mode, which specifically includes the following steps: calling a bottom layer interface according to preset management conditions; according to the bottom layer interface, the audio data cache of the channel outside the target channel is emptied, so that the audio outside the target channel is muted; and acquiring and sending the audio data of the target channel to a playing unit, so that the playing unit plays the audio of the target channel.

Taking the target channel as the second channel as an example, in the single channel mode/focus mode, the second channel is determined to be the target channel through corresponding operation of a user, and the preset management conditions are the same, so that the bottom layer interface is directly called through the application layer, the audio data cache of the first channel is emptied through the bottom layer interface, then the audio data cache of the second channel is obtained, the audio data caches of the first channel and the second channel are combined and sent to the playing unit (because the audio data cache of the first channel is emptied, only the audio data of the second channel are obtained at the moment), and finally the loudspeaker is driven through the playing unit, so that the purposes of silencing the audio of the first channel and playing the audio of the second channel are achieved.

According to the audio management method provided by the embodiment of the application, a user can select a proper target audio management mode according to different use scenes by himself, the method is not limited to a certain independent audio management mode, in addition, the single-channel mode and the focus mode in the target audio management mode can realize independent mute of the audio of a certain channel, different audio management strategies are realized, and the audio playing effect is improved.
