Detailed Description

In order to make those skilled in the art better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

The embodiment of the application provides a display device and a volume adjusting method.

The display device provided in the present application may be a display device having a plurality of controller architectures, such as the display device having a controller (dual hardware system) architecture shown in fig. 5 to 6 of the present application, or may be a display device having a non-dual controller architecture, which is not limited in the present application.

The volume adjusting method provided by the application can be applied to display equipment such as a smart television, and certainly can also be applied to other handheld equipment which can provide voice and data communication functions and has a wireless connection function, or other processing equipment which can be connected to a wireless modem, such as a mobile phone (or called a cellular phone) and a computer with a mobile terminal, and can also be a portable, pocket, handheld, computer built-in or vehicle-mounted mobile device which exchanges data with a wireless access network.

For the convenience of users, various external device interfaces are usually provided on the display device to facilitate connection of different peripheral devices or cables to implement corresponding functions. When a high-definition camera is connected to an interface of the display device, if a hardware system of the display device does not have a hardware interface of a high-pixel camera receiving the source code, data received by the camera cannot be displayed on a display screen of the display device.

Furthermore, due to the hardware structure, the hardware system of the conventional display device only supports one path of hard decoding resources, and usually only supports video decoding with a resolution of 4K at most, so when a user wants to perform video chat while watching a network television, the user needs to use the hard decoding resources (usually GPU in the hardware system) to decode the network video without reducing the definition of the network video screen, and in this case, the user can only process the video chat screen by using a general-purpose processor (e.g. CPU) in the hardware system to perform soft decoding on the video.

The soft decoding is adopted to process the video chat picture, so that the data processing burden of a CPU (central processing unit) can be greatly increased, and when the data processing burden of the CPU is too heavy, the problem of picture blocking or unsmooth flow can occur. Further, due to the data processing capability of the CPU, when the CPU performs soft decoding on the video chat screen, multi-channel video calls cannot be generally implemented, and when a user wants to perform video chat with multiple other users in the same chat scene, access is blocked.

In view of the above aspects, to overcome the above drawbacks, the present application discloses a dual hardware system architecture to implement multiple channels of video chat data (at least one channel of local video).

The concept to which the present application relates will be first explained below with reference to the drawings. It should be noted that the following descriptions of the concepts are only for the purpose of facilitating understanding of the contents of the present application, and do not represent limitations on the scope of the present application.

The term "module" as used in the various embodiments of the present application may refer to any known or later developed hardware, software, firmware, artificial intelligence, fuzzy logic, or combination of hardware and/or software code that is capable of performing the functionality associated with that element.

As an embodiment, the number of the cameras used in the present application may be 1600 ten thousand, so as to achieve the purpose of ultra high definition display. In actual use, cameras higher or lower than 1600 ten thousand pixels may also be used.

After the display equipment is provided with the camera, contents displayed by different application scenes of the display equipment can be fused in various different modes, so that the function which cannot be realized by the traditional display equipment is achieved.

Illustratively, the user can have a voice call with at least one other user (i.e., at least one other terminal) while enjoying the audio/video program. The audio and video program can be presented as a background picture, the sound of the audio and video program can be used as background sound, a window for voice communication is displayed on the background picture, and the sound of the voice communication can be played simultaneously with the background sound through the display equipment.

Vividly, the function of simultaneously playing the two paths of sound by the display device can be called as 'chat while watching' and the scene in which the two paths of sound exist simultaneously is called as 'chat while watching' scene.

In other exemplary embodiments, in a "while-watching chat" scenario, the chat window may not be presented, but only the chat speech is output. That is, the display plays the audio and video program, and the program sound and the chat sound are output simultaneously.

In other exemplary embodiments, in a "chat while watching" scenario, when a user triggers an instruction to mute the chat sound, only the audio/video program sound is output, and the chat speech of other users is converted into text or bullet screen form and presented on the display.

In another example, a user may conduct a video chat with at least one other user while entering learning from an educational application. For example, a student may interact remotely with a teacher while learning content in an educational application. Vividly, this function can be called "chatting while learning".

In another example, a user conducts a video chat with a player entering a card game while playing the game. For example, a player may enable remote interaction with other players while entering a gaming application to participate in a game. Figuratively, this function may be referred to as "watch while playing".

Optionally, the game scene is fused with the video picture, the portrait in the video picture is scratched and displayed in the game picture, and the user experience is improved.

Optionally, in the motion sensing game (such as ball hitting, boxing, running and dancing), the human posture and motion, limb detection and tracking and human skeleton key point data detection are obtained through the camera, and then the human posture and motion, the limb detection and tracking and the human skeleton key point data detection are fused with the animation in the game, so that the game of scenes such as sports and dancing is realized.

In another example, a user may interact with at least one other user in a karaoke application in video and voice. Figuratively, the function may be called "sing while looking". Preferably, when at least one user enters the application in a chat scenario, a plurality of users can jointly complete recording of a song.

In another example, a user may turn on a camera locally to take pictures and videos, figurative, which may be referred to as "looking into the mirror".

In other examples, more or less functionality may be added. The function of the display device is not particularly limited in the present application.

For example, a live television application may provide television signals using input from cable television, radio broadcasts, satellite services, or other types of live television services. And, the live television application may display video of the live television signal on display device 200.

A video-on-demand application may provide video from different storage sources. Unlike live television applications, video on demand provides a video display from some storage source. For example, the video on demand may come from a server side of the cloud storage, from a local hard disk storage containing stored video programs.

The media center application program can provide various applications for playing multimedia contents. For example, a media center, which may be other than live television or video on demand, may provide services for a user to access various images or audio through a media center application.

The application center may obtain these applications from different sources, store them in local storage, and then be operable on the display device 200.

Since the first controller and the second controller may have independent operating systems installed therein, there are two independent but interrelated subsystems in the display device 200. For example, android (Android) and various APPs can be independently installed on the first controller and the N, so that each chip can realize a certain function, and the first controller and the second controller cooperatively realize a certain function.

A schematic diagram of a user interface in a display device 200 according to an exemplary embodiment is illustrated in fig. 7. As shown in fig. 7, the user interface includes a plurality of view display windows, illustratively, a first view display window 201 and a play screen 202, wherein the play screen includes a layout of one or more different items. And a selector in the user interface indicating that the item is selected, the position of the selector being movable by user input to change the selection of a different item.

It should be noted that the multiple view display windows may present display screens of different hierarchies. For example, a first view display window may present video chat project content and a second view display window may present application layer project content (e.g., web page video, VOD presentations, application screens, etc.).

Optionally, the presentation of the different view display windows has priority difference, and the display priorities of the view display windows are different among the view display windows with different priorities. If the priority of the system layer is higher than that of the application layer, when the user uses the acquisition selector and the picture switching in the application layer, the picture display of the view display window of the system layer is not blocked; and when the size and the position of the view display window of the application layer are changed according to the selection of the user, the size and the position of the view display window of the system layer are not influenced.

The same level of display may also be presented, in which case the selector may switch between the first view display window and the second view display window, and when the size and position of the first view display window changes, the size and position of the second view display window may change accordingly.

In some embodiments, in a chat-while-watching scenario, the display device plays at least two sounds simultaneously.

Fig. 8 illustrates a user interface in a chat-while-watching scenario in which a display device is simultaneously playing a video program and making a voice call with three end-users. As shown in fig. 8, the display device plays the video program in full screen, and the voice call window is suspended on the video playing screen in the form of a small window.

It should be noted that the chat while watching scene is not limited to the above exemplary illustrated scene in which a voice call is performed while watching a video program, but also includes a scene in which a video call is performed while listening to a video program. In addition, if the video program or the audio program is paused or the display presents a static user interface instead of a dynamic video image when the voice call is performed, because the audio output channel of the video program is always in the on state, the scene is also regarded as the scene with at least two paths of sound, i.e., the chat scene while watching.

It should be further noted that the audio/video program played by the display device may be a live television program or a network program.

It should be further noted that, in the chat scene while watching, the display device may perform multi-channel video chat with a plurality of other terminal devices while playing the audio and video program. That is, in the chat scene while watching, the display device may play more than 2 sound signals at the same time.

Referring to fig. 9, in the chat-while-watching scenario, the controller may receive at least two audio data, one of which is audio data of an audio and video program, the audio and video program further includes a live television program and a network program, and the other of which is audio data of a voice call. The controller respectively decompresses and decodes the at least two paths of audio data, performs noise reduction, digital-to-analog conversion, amplification processing and other audio data processing on the at least two paths of audio data according to a standard coding and decoding protocol of the input signal through the audio processor 260, superimposes at least sound signals after processing, sends the superimposed sound signals to the audio output interface 270 (such as a loudspeaker 272), and finally outputs the sound of the audio and video program and the sound of voice call through the audio output interface 270, for example, plays the sound of the audio and video program and the sound of the voice call through the loudspeaker 272.

In the above-described chat while watching scenario, the user can normally operate the display device by operating the control device.

In some embodiments, the user can adjust the output volume value of the sound signal by operating the control device, and the power amplifier manager controls the gain of the sound signal according to the output volume value set by the user. For example, the output volume of the sound signal may be adjusted by operating a physical volume key (volume +, volume-) or a virtual volume key on a device such as a remote controller or a mobile terminal, or a voice input.

For example, when the display displays the user interface as shown in fig. 8, if the controller receives an instruction indicating to adjust the volume input by the user through the operation control device 100, the controller displays an interface element indicating the currently output volume, which may be a volume adjustment bar as shown in fig. 10, on an upper layer of the user interface in response to the instruction. The user can obtain the current output volume value of the sound signal according to the volume value shown by the volume adjusting bar, and the power amplifier manager controls the gain of the sound signal according to the output volume value.

In the above example, since the power amplifier manager in the audio processor simultaneously adjusts and superimposes the gains of the sound signal of the television program and the sound signal of the voice call according to the same output volume value, the output volume of the television program is the same as the output volume of the voice call. Furthermore, from the perspective of the user, in a scene of 'chat while watching', two paths of sounds are mixed together and interfere with each other, so that the user cannot recognize the sounds.

To this end, the embodiment of the application proposes an interaction design for volume adjustment for the above-mentioned chat while watching scenario, and fig. 8 and fig. 11 to 13 exemplarily show a schematic diagram of a volume adjustment interaction process in the chat while watching scenario.

In some embodiments, when playing the audio and video program and performing the voice call simultaneously as shown in fig. 8, the user may input an instruction indicating to adjust the volume by operating the control device, and the controller may present, in response to the instruction, a volume setting interface on the display, where the volume setting interface displays interface elements for representing an output volume of the audio and video program and also displays volume setting items for associating the output volume of the voice call with the output volume of the audio and video program.

Fig. 11 exemplarily shows a volume setting interface, as shown in fig. 11, which is displayed in a form of a view window in a floating manner on an upper layer of a play screen of an av program and a voice call window, and includes a volume adjustment bar 111 for indicating an output volume value of the av program, and volume setting items 112 to 114, the volume setting items 112 to 114 being a "standard mode" 112, a "flood mode" 113, and an "AI mute mode" 114, respectively.

In this embodiment, the volume setting item is used to associate the output volume of the voice call with the output volume of the audio/video program, specifically, the user directly adjusts the output volume of the audio/video program by operating the control device, and the controller performs associated adjustment on the output volume of the voice call according to the output volume value of the audio/video program, so that the output volumes of the audio/video program and the controller are different. For example, the controller adjusts the output volume value of the voice call to a second volume according to the first volume of the output volume value of the audio/video program, wherein the first volume is related to the second volume, and the first volume is not equal to the second volume.

In some possible implementation manners, one adjustment coefficient is preset for one volume setting item, and the adjustment coefficients corresponding to different volume setting items are different. The adjusting coefficient is used for being multiplied by the output volume value of the audio and video program to obtain the output volume value of the voice call, so that the output volume of the audio and video program is different from the output volume of the voice call. Of course, when the adjustment coefficient corresponding to a certain volume setting item is 1, the output volume value of the voice call is not changed relative to the output volume value of the audio/video program, and thus, the output volume value of the audio/video program is the same as the output volume value of the voice call.

For example, three volume setting items 112 to 114 shown in fig. 11 respectively correspond to one adjustment coefficient, specifically, the adjustment coefficient corresponding to the "standard mode" 112 may be 1.1, which means that during a voice call, a human voice volume value of an opposite end user may be increased by 10% relative to a playing volume value of an audio/video program; the adjustment coefficient corresponding to the "surging mode" 113 may be 1.2, which means that the voice volume value of the opposite-end user may be increased by 20% relative to the playing volume value of the audio/video program when the video chat is performed; the adjustment coefficient corresponding to the "AI mute mode" 114 may be 0, which means that the voice volume of the opposite user is muted during the voice call.

In some embodiments, when the display displays the volume setting interface as shown in fig. 11, the user may input an instruction to adjust the volume by continuing to operate a volume key (volume + or volume-) on the control device, and the controller, in response to the instruction, obtains a default item pre-stored in the volume setting items, and then performs associated adjustment on the output volume of the audio/video program and the output volume of the voice call according to the default item. For example, in the "standard mode" 112 in the selected state in fig. 11, the controller obtains the adjustment coefficient 1.1 corresponding to the "standard mode" 112, and then adjusts the output volume of the voice call to the second volume according to the output volume value of the audio/video program, i.e., the first volume, where the second volume = the first volume × 1.1.

In some embodiments, when the display displays the volume setting interface shown in fig. 11, a user may select a certain volume setting item by operating the control device, and the controller performs associated adjustment on the output volume of the audio/video program and the output volume of the voice call according to the selected volume setting item, so that the output volume after the voice call adjustment is different from the output volume after the audio/video program adjustment. For example, the user operates the control device to select the "surging mode" 113, the controller responds to the user operation to acquire the adjustment coefficient 1.2 corresponding to the "surging mode" 113, and then adjusts the output volume of the voice call to a second volume according to the first volume of the output volume value of the audio/video program, wherein the second volume = the first volume × 1.2.

It can be seen from the above examples that the "standard" mode and the "flood and bright" mode can achieve the effect of enhancing human voice, so that in the chat scene while watching, the sound of the audio and video program is played as the background sound, and the sound of the voice call is played as the foreground sound, so that the user can easily distinguish the source of the sound respectively, and confusion is avoided.

It should be noted that the adjustment coefficients of the "standard mode" 112 and the "flood mode" 113 are not limited to 1.1 or 1.2, and in other embodiments, the "standard mode" 112 and the "flood mode" 113 may be any preset values.

In some embodiments, the volume setting items displayed in the volume setting interface are not limited to the three types, and in other embodiments, other volume setting items may be provided for the user according to the user's requirement, so as to be selected by the user.

In some embodiments, the effect of reducing the voice is achieved by adjusting the adjustment coefficient corresponding to the volume setting item, for example, when the adjustment coefficient corresponding to a certain volume setting item is 0.5, it means that the voice volume value of the opposite-end user can be reduced by 50% relative to the playing volume value of the audio and video program when the video chat is performed, and thus the effect of reducing the voice is achieved.

According to the embodiment provided by the application, in the chat scene while watching, the volume of at least two paths of sounds played by the display device at the same time is adjusted in a correlated manner, so that the at least two paths of sounds can be played at different output volumes, and a user can easily distinguish the source of the sounds respectively.

It is noted that the "AI mute mode" shown in fig. 11 may correspond to an adjustment factor of 0, which means that the volume of the voice of the video chat is reduced to 0. In order to still not affect the realization of the chat function under the condition of muting the voice call, when the "AI mute mode" is selected (i.e. turned on), the text corresponding to the call audio data can be distributed on the upper layer of the playing picture in the form of a bullet screen.

For example, in the chat scenario shown in fig. 11, when the preset default mode is the "AI mute mode" 114 shown in fig. 11, or when the user selects the "AI mute mode" 114 shown in fig. 11 by operating the control device, the controller stops playing the sound signal of the voice call, and presents the text corresponding to the voice call data corresponding to the peer device on the top layer of the user interface in the form of a bullet screen, for example, as shown in fig. 12.

The following describes an implementation of the "AI silent mode" 114 by taking the display device 200B as an example, wherein the display device 200B performs a voice call with one or more other terminal devices while playing an audio/video program. The following is an exemplary description of a voice call communication procedure of the display apparatus 200B and the display apparatus 200A.

In some possible implementation manners, the text corresponding to the voice call data is converted by the data sending end according to the call data collected by the data sending end, and the converted text is sent to the data receiving end to be displayed. Specifically, the display device 200A collects call data a of the user through a microphone; in a case where the display device 200B does not turn on the "AI mute mode" 114, the display device 200A transmits the collected call data a to the display device 200B; under the condition that the display device 200B starts the "AI silent mode" 114, the display device 200A synchronizes the acquired call data a to the voice server, and performs recognition conversion on the call data a through the voice server to obtain a text a corresponding to the call data a; and then sends the text a to the display device 200B. For the display device 200B, in the case that the "AI silent mode" 114 is not turned on, receiving the call data a sent by the display device 200A, extracting a voice call sound signal from the call data a, processing the voice call sound signal through the power amplification manager, and playing the processed sound signal through the speaker; notifying the display apparatus 200A when it receives a user input of a selection operation for the "AI silent mode" 114; when the display device 200B turns on the "AI mute mode" 114, the display device 200B receives the text a sent by the display device 200A and displays the text a on the top layer of the user interface in real time, thereby achieving the display effect as shown in fig. 11.

As can be seen from the above example, when receiving an operation of selecting the "AI silent mode" 114 by a user input on the volume setting interface as shown in fig. 11, the display device 200B notifies the display device 200A so that the display device 200A converts the call data a collected by the display device into text a and then transmits the text a to the display device 200B.

In other possible implementation manners, the data receiving end performs recognition conversion on the call data received by the data receiving end to obtain a corresponding text and displays the text. Specifically, the display device 200A collects call data a of the home terminal user through a microphone, and sends the collected call data a to the display device 200B; for the display device 200B, in the case that the "AI silent mode" 114 is not turned on, receiving the call data a sent by the display device 200A, extracting a voice call sound signal from the call data a, processing the voice call sound signal through the power amplification manager, and playing through the speaker; under the condition that the display device 200B opens the "AI silent mode" 114, the display device 200B receives the call data a sent by the display device 200A, synchronizes the received call data a to the voice server, and performs recognition conversion on the call data a through the voice server to obtain a text a corresponding to the call data a; text a is then displayed on the top level of the user interface.

It should be noted that, in the case where the display device 200B turns on the "AI mute mode" 114, it has a certain time delay Ta for displaying the text a, where the time delay Ta is at least the time length required for the display device 200A or the display device 200B to recognize the text a through the voice server.

Fig. 13 illustrates another volume setting interface, and unlike the interface illustrated in fig. 11, the interface illustrated in fig. 13 further includes an item "volume-associated adjustment switch" 115 for turning on or off the above-described volume-associated adjustment function, and a user can turn on or off the volume-associated adjustment function by operating the item. Specifically, if the volume-related adjustment function is in an on state, each volume setting item in the interface is an item that can be operated, and can be selected by user operation; if the volume-related adjustment function is in the off state, the volume setting item is an inoperable item, and thus cannot be selected by user operation.

In the scenario shown in fig. 11, 12, or 13, the user cancels the display of the volume setting interface by operating a key on the control device, such as a "return" key, an "exit" key, or the like, to return to the interface shown in fig. 8.

The present application also provides a volume control method, which can be applied to a display device as shown in fig. 1 to 13, and the method is performed by a display device controller, but is not limited thereto. Fig. 14 is a flowchart illustrating a volume control method according to some embodiments of the present application, where as shown in fig. 14, the method may include:

and step 01, receiving an instruction which is input by a user and indicates to adjust the volume when the audio and video program is played and the voice call is simultaneously carried out.

For convenience of description, the embodiment of the present application provides a concept of a sound playing scene, where the sound playing scene of the display device includes a chat scene while watching and a common scene. The chat scene while watching refers to a scene including two or more sound signal outputs, for example, a scene in which audio and video program playing and voice communication are simultaneously performed.

In some embodiments, when an instruction indicating to adjust the volume is received, which is input by a user, it is determined whether a current sound playing scene is a chat while watching scene, if so, step 02 is performed, and if not, i.e., a common scene, an interface as shown in fig. 10 is presented, and the volume of the video and audio program played by the display device is adjusted according to the input by the user.

In some possible implementation manners, whether the current sound playing scene is a chat scene while watching can be judged by detecting the running condition of the foreground application, that is, whether the audio and video program playing and the voice call are performed simultaneously. For example, if it is detected that the audio/video chat window object is running, it indicates that the audio/video chat is in progress, so that the current sound playing scene is a chat while watching scene, and if it is detected that the audio/video chat window object is not running, it indicates that the audio/video chat is not started currently, so that the current sound playing scene is not a chat while watching scene, that is, a common scene.

In some embodiments, the user may input an instruction instructing to adjust the volume by operating the control device. For example, when the user presses a physical volume key on the remote control 100A for increasing or decreasing the volume, the controller receives an instruction to increase or decrease the volume sent by the remote control. For another example, when the user clicks a virtual volume key on the mobile terminal 100B for increasing or decreasing the volume, the controller receives an instruction to increase or decrease the volume sent by the mobile terminal. In addition, the user may also input a voice command for increasing or decreasing the volume through a remote controller, a display device, or a microphone on the mobile terminal. The user may also enter an instruction to increase or decrease the volume by pressing a local volume button on the display device housing to increase or decrease the volume.

And step 02, responding to the instruction for indicating the adjustment of the volume, and presenting a volume setting interface on a display, wherein the volume setting interface comprises an interface element for representing the output volume of the audio and video program and a volume setting item for associating the output volume of the voice call with the output volume of the audio and video program.

The volume setting interface involved in step 02 may be the volume setting interface shown in fig. 11, the interface element used for representing the output volume of the audio-video program may be the volume adjustment bar 111 in fig. 11, and the volume setting items may be items 112 to 114 in fig. 11.

And 03, responding to the selection operation of the volume setting item by the user, and performing correlation adjustment on the output volume of the audio and video program and the output volume of the voice call according to the selected volume setting item so as to enable the output volume after the voice call adjustment to be different from the output volume after the audio and video program adjustment.

In the present application, the audio STREAM sources of the sound signals include television program audio and other audio based on physical type channels (ATV, DTV, HDMI, etc.), and the audio STREAM types of the other audio are mainly network program audio (STREAM _ MUSIC) and CALL audio (STREAM _ VOICE _ CALL) based on network type channels. The television program audio based on the physical type channel (ATV, DTV, HDMI, etc.) and the network program audio based on the network type channel (STREAM _ MUSIC) are audio of an audio and video program, and the CALL audio (STREAM _ VOICE _ CALL) is audio of a VOICE CALL.

For different types/audio stream source sound signals, the output volume values thereof can be independently adjusted to independently control the gains thereof according to the corresponding output volume values.

As shown in fig. 9, the output volume control mainly includes two branch types, which are a main volume MainVoice and a sub volume subtivoice, respectively, and the sub volume subtivoice further includes a first sub volume music Voice and a second sub volume calvoice, where the main volume MainVoice is the volume corresponding to the television program, the first sub volume music Voice is the volume corresponding to the network program, and the second sub volume Call Voice is the volume corresponding to the Voice Call.

Based on the method, when an instruction which indicates to adjust the volume and is input by a user is received, the output volume value of the audio and video program is adjusted according to the audio stream source of the audio and video program, and then the output volume value of the voice call is adjusted in a correlation mode according to the output volume value of the audio and video program.

Specifically, an audio stream source of the audio and video program is obtained, where the audio stream source is a television program based on a physical type channel or a network program based on a network type channel. If the audio stream source of the audio and video program is a television program, adjusting a main volume value (MainVoice) to a first volume, wherein the main volume value is the output volume value of the television program; if the audio stream source of the audio and video program is the network program, adjusting a first sub-volume value (MusicVoice) to a first volume, wherein the first sub-volume value is the volume value of the network program.

And then, multiplying the first volume by an adjusting coefficient corresponding to the selected volume setting item to obtain a second volume, wherein the second volume is the target volume of the voice call, and further adjusting a second sub volume value (CallVoice) to the second volume, wherein the second sub volume value is the volume value of the voice call.

As can be seen from the above example, in the chat while watching scene, by performing correlated adjustment on the volume of at least two sounds played simultaneously by the display device, the at least two sounds can be played at different output volumes, so that the user can easily identify the source of the sound respectively.

In some embodiments, when the display displays the volume setting interface as shown in fig. 11, if an instruction for adjusting the volume is received, which is input by a user, a default item pre-saved in the volume setting items is acquired; and then, carrying out associated adjustment on the output volume of the audio and video program and the output volume of the voice call according to the default item.

In some embodiments, in response to an instruction input by a user and instructing to adjust the volume, a default item pre-saved in the volume setting items is acquired while a volume setting interface is presented; and then, carrying out associated adjustment on the output volume of the audio and video program and the output volume of the voice call according to the default item.

In the above example, the default item may be a volume setting item selected by the user in the last operation, or may be a volume setting item defaulted by the system.

In a specific implementation, the status flag may be performed for each volume setting item, for example, the volume setting item selected by the user or the default volume setting item of the system is marked as the selected status, and the remaining volume setting items are marked as the unselected status. Further, the default item may be acquired by traversing the flag state of each volume setting item.

In other embodiments, before acquiring the default item, it is determined in advance whether the volume-related adjustment function shown in fig. 13 is in an on state, if so, the default item is acquired, and if not, the process is ended.

In some embodiments, when a mute instruction input by a user through operation of the control device is received in the chat while watching scene, the output volume of the audio and video program and the output volume of the voice call are simultaneously adjusted to 0.

In some embodiments, when an AI mute instruction input by a user is received in a chat while watching scene, in response to the AI mute instruction, the playing of the voice signal of the voice call is stopped, and a text corresponding to the call data is published on an upper layer of the playing screen in a bullet screen manner. For example, when the display displays a volume setting interface as shown in fig. 11, the user can select the "AI mute mode" 114 by operating the control device to input an AI mute instruction.

During specific implementation, a text corresponding to the call data and user information corresponding to the call data are respectively obtained, and the user information is used for representing a user account for sending the call data, such as a user nickname, a user ID, a user head portrait and the like. Then generating bullet screen characters according to the text corresponding to the call data and the user information; and then, displaying bullet screen characters carrying user information marks on the upper layer of a playing picture displayed by the display.

In particular implementations, the present invention also provides a computer storage medium, where the computer storage medium may store a computer program, and when the computer program is executed by at least one controller/processor of a display device, the controller/processor performs some or all of the steps shown in fig. 14. The storage medium may be a magnetic disk, an optical disk, a read-only memory (ROM) or a Random Access Memory (RAM).
