When the display device is used for carrying out video call, in order to provide richer experience for a user, the display device provided by the embodiment of the invention can be used for continuously playing the audio and video file at the local terminal when carrying out video call with the opposite terminal, so that an application scene of 'chatting while watching' is realized.

In order to avoid that the output volume of the audio and video file affects the video call, so that a user at the local end cannot hear the speaking sound of the opposite end clearly, the embodiment of the invention provides a media volume adjusting method, which can automatically reduce the output volume of the audio and video file when the sound of the local end and the sound of the opposite end are collected, and automatically recover the output volume of the audio and video file when the sound of the local end or the sound of the opposite end is not collected. Therefore, the method provided by the embodiment can automatically control the output volume of the audio and video files according to the scene under the scene of chatting and watching, ensure the effects of watching and calling experience and improve the user experience.

The media volume adjusting method provided by the embodiment of the invention is applied to display equipment, the display equipment can be an intelligent television and the like, and the intelligent television is internally provided with an APP capable of playing audio and video files and an APP capable of carrying out audio and video communication (video call). The display device may be an intelligent terminal configured with a single system, or may be an intelligent terminal configured with a dual system, and this embodiment is not particularly limited.

Fig. 6 is a flowchart illustrating a media volume adjustment method according to an embodiment; fig. 7 is a data flow diagram illustrating a media volume adjustment method according to an embodiment. Referring to fig. 6 and 7, an embodiment of the present invention provides a media volume adjusting method, where an execution subject is a controller in a display device, the method includes the following steps:

and S1, detecting the sound input of the local terminal device and the sound input of the opposite terminal device corresponding to the audio and video communication when the audio and video file is played and the audio and video communication is carried out simultaneously.

The display device provided by the embodiment of the invention can play the audio and video files and carry out video call (audio and video communication) simultaneously when the social function is presented. For example, in the process of playing the audio and video file, a video call request sent by other users can be answered, or in the process of carrying out video call with other users, the audio and video file can be played, so that a scene of 'chatting while watching' is realized.

When the display device is started, the local user can receive video call requests from other users, wherein the display device is the local device, the devices used by the other users are opposite-end devices, and the devices of the opposite-end users can be display devices and other intelligent terminals.

For the multiple implementation scenarios of "chatting while watching", in order to avoid that the output volume of the audio/video file played in the display device affects users of both parties performing the audio/video communication when the display device performs the audio/video communication, the method provided by this embodiment can adjust the output volume of the audio/video file in the "chatting while watching" scenario, so as to ensure the effects of watching and talking experience of the user, and improve the user experience.

For example, when the local device is playing an audio/video file, in the process, other users send a video call request, and the process of adjusting the output volume of the audio/video file by the local device includes:

and S01, receiving the video call request when the media resource is played.

And S02, responding to the video call request, displaying the video call interface, and stopping playing the media resource.

And S03, responding to an interface switching instruction, reducing the playing volume value of the media resource, wherein the interface switching instruction is used for switching the video call interface into a small window interface.

If the local terminal user operates the display device to receive the video call request, the video call (audio and video communication) between the local terminal device and the opposite terminal device is connected, and at the moment, a video call interface is displayed on the display device. The video call interface may be in a full-screen display state or an enlarged display state, and this embodiment is not particularly limited.

When the local terminal display equipment is connected with the video call, the playing of the audio and video files is immediately stopped, and the influence of the sound output by the audio and video files in the playing state on the effect of the video call is avoided. If the local user operates the display device to be in the video call state all the time and does not enter the scene of chatting and watching at present, at the moment, the video call interface is kept in the full-screen display state or the amplified display state, the audio and video files are in the playing stop state before the video call is finished, and the audio and video files are continuously played until the video call is finished.

However, if the home terminal user operates the display device to reject the video call, at this time, the display device does not respond to the video call request, and the audio/video file continues to be played.

If the user at the home terminal wants to enter a scene of chatting and watching, namely, the user carries out video call (audio and video communication) and watches audio and video files, at the moment, the display equipment at the home terminal can be operated to switch the video call interface from a full-screen display state or an amplified display state into a small-window state. And the small window state is a floating window state, and the video call interface is reduced and displayed to form a small window interface so as to expose the playing interface of the audio and video file.

The home terminal user can talk with the remote controller to operate the display device and generate an interface switching instruction, so that the video call interface is switched to a small window state. And responding to the interface switching instruction by a controller of the display equipment, and continuously playing the audio and video file after finishing the video call interface switching. In order to avoid that the output volume of the audio and video file affects the process of the video call in the scene of chatting and watching, in this embodiment, the playing volume of the audio and video file is adjusted, so that the local user can clearly distinguish the volume of the audio and video file from the volume of the opposite terminal device in the video call while the audio and video file is played, and the effects of watching and calling experience are ensured.

In this embodiment, the playing volume of the audio/video file is adjusted according to the sound input of the local device and the sound input of the opposite device, and the input sounds of the devices at the two ends are detected to adjust in real time.

A flow chart of a method for detecting sound input of a local device according to an embodiment is illustrated in fig. 8. Specifically, referring to fig. 8, in step S1, detecting the sound input of the home device corresponding to the audio/video communication includes:

and S111, detecting voice data input by a microphone of the local terminal equipment.

And S112, if the voice data meet the preset conditions, the local terminal equipment has voice input.

And S113, if the sound data do not meet the preset conditions, the local terminal equipment does not have sound input.

The equipment used for receiving the sound of the local terminal equipment is a microphone, and the microphone is arranged on the display equipment and connected with the controller. The controller in the local terminal display equipment detects the sound data input by the local terminal microphone in real time, and if the sound data can be detected, the sound data indicates that the local terminal equipment generates sound in the environment.

The sound generated by the environment in which the local device is located may be the sound of the local user speaking, or may be noise generated by the environment in which the local device is located, such as the sound generated by other indoor appliances, the sound generated by outdoor vehicles or pedestrians. When the home terminal user uses the display device, the distance from the home terminal user to the display device is usually short, so that the sound data detected by the display device is large; and the sound of other equipment or from the outdoors is far away from the local display equipment, so that the sound data detected by the display equipment is small. Therefore, in order to accurately distinguish that the sound generated by the environment where the local terminal equipment is located is the sound from the speaking of the local terminal user, the sound data can be judged by setting the preset condition.

The preset condition may be a threshold of sound data, and the sound data may be expressed in decibels. If the voice data of the local terminal equipment is detected to meet the preset condition, namely the voice data is higher than the voice data threshold value, the voice of the local terminal can be determined to be the voice of the user, namely the voice input of the local terminal equipment is determined. And if the detected sound data of the local terminal does not meet the preset condition, namely is lower than the sound data threshold, determining that the sound of the local terminal is sound from the outside or the inside, namely determining that no sound input exists in the local terminal equipment.

In some embodiments, the microphone of the local device may be a microphone disposed on the display device body, or may be a microphone disposed on the remote controller.

In some embodiments, the signal strength/amplitude transmitted by the local microphone array to the processor may also be detected to characterize the input of sound data.

In some embodiments, the frequency spectrum of the sound data may be analyzed to determine whether the sound data satisfies a predetermined condition.

Fig. 9 is a flowchart illustrating a method for detecting a voice input of a peer device according to an embodiment. In step S1, referring to fig. 9, detecting a sound input of an opposite terminal device corresponding to the audio/video communication includes:

and S121, detecting whether a callback instruction sent by the opposite terminal device is received, wherein the callback instruction is an instruction sent by the opposite terminal device when the opposite terminal device carries out audio and video communication with the local terminal device and the opposite terminal device transmits voice data to the local terminal device.

And S122, if the callback instruction is received, the opposite terminal equipment has sound input.

And S123, if the callback instruction is not received, the opposite terminal equipment does not have sound input.

When the local terminal user and the opposite terminal user carry out video call, a call link is formed between the local terminal device and the opposite terminal device, and when the opposite terminal device speaks, the opposite terminal device sends session data to the local terminal device and simultaneously sends a callback instruction to the local terminal display device. Therefore, after the controller of the local display device receives the callback instruction sent by the opposite terminal device, it can be determined that the opposite terminal user is speaking, that is, the local display device can detect the opposite terminal radio reception state according to the callback instruction sent by the opposite terminal.

The method comprises the steps that a display device detects whether an opposite terminal device sends a callback instruction in real time in the process of chatting and watching, if the callback instruction sent by the opposite terminal is received, an opposite terminal user is speaking, and then the fact that sound input exists in the opposite terminal device can be determined; if the callback instruction sent by the opposite terminal equipment is not received, the fact that the opposite terminal user does not speak is indicated, and the fact that no sound input exists in the opposite terminal equipment can be determined.

And because the speaking sound of the opposite-end user is small sometimes, in order to accurately determine that the current conversation process is an effective conversation process, the display device can acquire the speaking volume of the opposite-end user, and when the volume of the opposite-end user is higher than a preset volume value, the effective conversation can be determined, and the preset volume value can be set to be 100 decibels or 200 decibels and can be determined according to specific conditions.

That is, only when the volume of the opposite terminal is higher than the preset volume value, the current call is determined as an effective call, and it is determined that the voice input exists in the opposite terminal device.

In some embodiments, the communication software does not output the local sound, but outputs the sound of the opposite end, and at this time, the audio data output by the communication software may be detected to determine whether the sound input is performed by the opposite end device.

In some embodiments, the communication software outputs the local sound and the opposite-end sound at the same time, so that the sound data of the opposite end can be obtained by detecting the audio data output by the communication software and the detected sound data input by the microphone to perform silencing, thereby determining whether the opposite end performs sound input.

And S2, if the local terminal equipment has sound input and/or the opposite terminal equipment has sound input, reducing the output volume of the audio and video file.

In the scene of chatting and watching, on the premise of ensuring the playing of the audio and video files and the simultaneous audio and video communication, in order to avoid the influence of the output volume of the played audio and video files on both parties of the audio and video communication, the method provided by the embodiment automatically reduces the output volume of the audio and video files when the two processes are simultaneously carried out.

Fig. 10 is a flowchart illustrating a method for reducing the output volume of an audio-video file according to an embodiment. In this embodiment, referring to fig. 10, reducing the output volume of the audio/video file includes:

s21, acquiring an initial output volume value of the audio/video file;

s22, determining a playable volume value according to the initial output volume value, wherein the playable volume value is smaller than the initial output volume value;

and S23, sending the playable volume value to the power amplifier manager, so that the power amplifier manager processes the audio data of the audio/video file according to the playable volume value, and sends the processed audio data and the processed audio data of the opposite terminal device to a loudspeaker for output after being superposed.

When an audio/video file is played and audio/video communication is carried out at the same time, a controller in the home terminal display equipment acquires an initial output volume value when the audio/video file is played; and calling a volume notification module, determining a playable volume value based on the initial output volume value, and sending the playable volume value to a power amplifier manager, wherein the playable volume value is 40% -60% of the initial volume value, and the power amplifier manager is used for adjusting the playable volume value of the audio/video file to the playable volume value.

The controller obtains the time for initially outputting the volume value of the audio/video file, and the controller can open and play the audio/video file when a video call interface in the display device is switched to a small window state or in the process of carrying out video call. For example, after the display device responds to the interface switching instruction, in order to adjust the output volume of the audio/video file, an initial output volume value of the audio/video file needs to be obtained first, wherein the initial output volume value refers to a volume value set by the display device when the audio/video file is played.

In this embodiment, the volume notification module is configured in the display device to transmit the volume. The volume notification module sends the determined playable volume value to the power amplifier manager, so that the power amplifier manager processes the audio data of the audio and video file according to the playable volume value, namely, the output volume of the audio and video file is reduced. The playable volume value can be 40% -60% of the initial output volume value, can be selected to be 50%, and the specific value can be determined according to the actual situation on the premise that the video call is not affected when the audio and video file is played.

When the power amplifier processor adjusts the output volume of the local terminal device, the power amplifier processor also needs to process the received sound input by the opposite terminal device, and finally, the processed audio data of the local terminal device and the processed audio data of the opposite terminal device are superposed and then sent to the loudspeaker for output.

And after entering a scene of chatting and watching, continuously playing the audio and video file and simultaneously carrying out audio and video communication based on the reduced playing volume value and the video call interface of the small window state. The display device plays the audio and video files while maintaining the video call state. At the moment, the video call interface is in a small window state, and the output volume of the audio and video file is 40% -60% of the original volume. The local terminal user can watch the media resources and carry out video call at the same time, and can clearly distinguish the volume of the media resources from the volume of the opposite terminal in the video call while playing the media resources, so that the effects of watching the video and calling experience are ensured.

Therefore, when the video call is carried out, the controller of the local terminal display equipment responds to the interface switching instruction and switches the video call interface into a small window interface; and responding to the audio and video file playing request, and reducing the output volume value of the audio and video file. And under the scene of chatting and watching, after the voice input of the local terminal equipment or the voice input of the opposite terminal equipment is detected, the playable volume value of the audio and video file is determined, and the output volume of the audio and video file is adjusted to make the output volume of the audio and video file lower than the initial output volume value.

And S3, if the local terminal device does not have sound input and the opposite terminal device does not have sound input, the output volume of the audio and video file is not reduced.

If the local controller does not detect that the local device has sound input and does not detect that the opposite device has sound input, which indicates that the local user and the opposite user are not speaking, then in order to ensure the normal playing of the audio/video file, the output volume of the audio/video file is not reduced, but the audio/video file is continuously played with the initial output volume value.

Wherein, the condition of not reducing the output volume of the audio and video file comprises: the condition that the output volume of the audio and video file is kept unchanged (the current detection process), and the condition that the reduced output volume is recovered to the initial output volume value (the next detection process).

In order to realize automatic adjustment of media volume according to a scene, namely control of output volume of an audio and video file, in the method provided by the embodiment of the invention, after a display device enters a scene of chatting and watching, whether a local terminal device has sound input or not and whether an opposite terminal device has sound input or not are continuously detected, so that the output volume of the audio and video file is controlled to be adjusted to normal volume when no sound input is collected at both ends; and when the sound at any end is collected for input, the output volume of the audio and video file is controlled to be adjusted to 40-60% of the original volume.

In order to adjust the output volume of the audio/video file efficiently, in this embodiment, when detecting whether the local device has sound input and the opposite device has sound input, it needs to judge with a certain frequency and a certain collection duration, and only if the local device and the opposite device have sound input within a period of time, the output volume value of the audio/video file is recovered.

Specifically, in order to avoid that the display device frequently reduces or recovers the play volume value of the media resource to cause the user dislike, the method provided in this embodiment detects whether the local device has sound input and the peer device has sound input according to the preset detection frequency and the preset times within the preset audio acquisition duration. The display equipment adjusts the output volume of the audio and video file according to whether the audio input of the local terminal equipment or the audio input of the opposite terminal equipment can be detected. If the local terminal equipment has sound input or the opposite terminal equipment has sound input within the preset audio acquisition duration, reducing the output volume of the audio/video file; and when the next preset audio acquisition time length is long, if the local terminal device does not have sound input and the opposite terminal device does not have sound input, determining that no sound is generated in the current video call process, namely the local terminal user and the opposite terminal user do not speak, and restoring the output volume value of the audio and video file to the initial output volume value.

In order to accurately control the output volume of the audio and video file, a preset detection frequency and preset times are set so as to ensure that the detection of the input sound of the local terminal equipment and the opposite terminal equipment is completed once within a preset audio acquisition duration. Specifically, the preset detection frequency may be set to be 500ms for one detection, the preset number of times is four, and the preset audio acquisition time is 2 s.

And detecting every 500ms within 2s, if the local terminal equipment does not have sound input and the opposite terminal equipment does not have sound input, indicating that the current local terminal user and the opposite terminal user do not chat, and calling a power amplifier manager to restore the output sound volume value of the audio and video file to the initial output sound volume value.

And if the display equipment recovers the output volume value of the audio/video file, the display equipment can continuously detect whether the local terminal equipment and the opposite terminal equipment have sound input in real time, and the local terminal equipment has sound input or the opposite terminal equipment has sound input, and the power amplifier manager is called to reduce the output volume of the audio/video file again.

For example, home user A chats with peer user B, C. If the A end speaks, the display equipment can utilize the microphone to receive sound, and the output volume of the audio and video file is reduced when the fact that the local end equipment has sound input is detected within 2 s; during the video call, the home terminal a and the opposite terminal B, C maintain a link of the call, and determine whether the opposite terminal device has sound input or not through the callback state of the link, that is, if the home terminal display device receives the callback instruction sent by the opposite terminal device within 2s, it detects that the opposite terminal device has sound input, and then reduces the output volume of the audio/video file. If the sound input of the local terminal device is not detected within 2s, and the sound input of the opposite terminal device is not detected, the output volume of the audio and video file is recovered, so that the user dislike caused by frequent switching is avoided.

In a detection period, a controller in the local terminal display device detects that sound input exists in the local terminal device or sound input exists in the opposite terminal device within a preset audio acquisition duration, and then the power amplifier manager reduces the output volume of the audio and video file according to the playable volume value; then, the detection is continued, and in the next detection period, the method provided in this embodiment further includes: in the next detection period, if the equipment does not have sound input and the opposite-end equipment does not have sound input, acquiring an initial output volume value of the audio and video file; and sending the initial output volume value to a power amplifier manager so that the power amplifier manager processes audio data of the audio and video file according to the initial output volume value, and sending the processed audio data and the processed voice data of the opposite terminal device to a loudspeaker for output after overlapping.

According to the method provided by the embodiment of the invention, when the audio and video file is adjusted in a scene of chatting and watching, the output volume of the audio and video file is automatically adjusted according to the sound input condition of the local terminal device and the sound input condition of the opposite terminal device which are detected in real time, for example, when the local terminal device has sound input or the opposite terminal device has sound input, the output volume of the audio and video file is reduced, and then if the sound input of the local terminal device and the sound input of the opposite terminal device cannot be detected, the output volume of the audio and video file is restored to the initial output volume value in time; and if the sound input of the local terminal equipment or the sound input of the opposite terminal equipment is detected again, the output volume of the audio and video file is reduced again. Therefore, the method can realize the automatic volume adjustment under the condition that the playing of the audio and video files and the audio and video communication are carried out simultaneously.
