Detailed Description

To make the objects, technical solutions and advantages of the exemplary embodiments of the present application clearer, the technical solutions in the exemplary embodiments of the present application will be clearly and completely described below with reference to the drawings in the exemplary embodiments of the present application, and it is obvious that the described exemplary embodiments are only a part of the embodiments of the present application, but not all the embodiments.

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.

The volume adjusting method provided by the embodiment is used for independently adjusting the background audio and video signal sound or the chat audio and video signal sound of the display device in a 'chat while being' scene. The method can be used for the display device provided by the embodiment, and can also be used for the display device with a non-double-chip architecture. In a 'chat while × while' scenario, a display device simultaneously and respectively displays different paths of audio and video signals through different windows, each window can display one path of audio and video signals, and a user can control the movement of a display focus between different windows through a remote controller or a virtual remote controller on a mobile phone to realize the selection of a specific window, the method includes the following steps S1201-S1203, which are specifically shown in fig. 12.

Step S1201, the display device receives a position selection instruction, where the position selection instruction is used to adjust a position of the focus frame in a display interface of the display device, and windows of different positions for representing different audio/video signals are selected.

In some embodiments, when the display device provides a chat service in the process of playing audio and video, the audio and video picture window and the chat window are simultaneously displayed on the display device. For example, in the display interface shown in fig. 13, the audio/video screen window is displayed in a full screen manner, and the chat window is displayed above the audio/video screen window in a manner of being overlaid by a floating layer (OSD).

In some embodiments, when the display device provides a game service during the playing of the audio and video, the game screen window and the chat window are simultaneously displayed on the display device. For example, in the display interface shown in fig. 13, the game screen window is displayed in full screen, and the chat window is displayed above the audio/video screen window in a manner of floating layer (OSD).

In some embodiments, the windows displayed simultaneously may also be presented in a picture-in-picture manner, with different windows corresponding to different audio-video streams.

In one example, the focus frame represents a position of the focus or a content selected by a user, and when a content (e.g., a control, a video window, a picture display position, etc.) is selected, to highlight the position of the focus frame, the selected content is set in a display screen of the display device as a highlighted image, such as a thick solid line box in the display interface shown in fig. 14-16. Taking a video chat scene as an example, a game is similar to a singing scene, and after receiving a position selection instruction, the display device can select to set the focus frame on an audio/video picture window or a chat window according to the position selection instruction. For example, as shown in fig. 14, the focus frame is selected to be set on the audio/video screen window; alternatively, for example, as shown in fig. 15, the focus frame is selected to be set on all chat windows; further alternatively, as shown in fig. 16, the focus frame is selected to be set on the dialog box of the chat object designated in the chat window.

In some embodiments, after the user removes the focus frame from the audio/video screen window through the left and right direction keys of the remote controller, the focus frame corresponds to the set window formed by all the video windows, at this time, if the television receives key values representing the left and right direction keys, the focus frame is moved to the audio/video screen window, and if the key values representing the up and down direction keys are received, the focus frame is moved to one of the video windows from the set window formed by all the corresponding video windows. In some embodiments, when the focus frame is in one video window, the display device may no longer respond to the key values representing the left and right direction keys, and only respond to the key values representing the up and down direction keys when the focus frame is in the last video window, if the key values representing the up and down direction keys are continuously received, the focus frame is switched from the last video window to the set window formed by all the video windows; in some embodiments, when the focus frame is in a video window, the display device may move the focus frame to the audio/video frame window in response to a key value representing a left-right direction key.

In this embodiment, the position selection command may be a command sent by a remote controller of the display device, or may be a command sent by a remote controller application installed on an intelligent display device such as a mobile phone. The audio/video signal corresponding to the audio/video screen window described in this embodiment includes the playing content of the video resource such as a live television, a network television, or a local video, but does not include a video chat screen. In other embodiments, the audio/video frame window may correspond to an audio/video stream of an APP application, where the APP may be a game APP or a song APP, and is not limited herein.

In addition, it should be noted that, in the embodiment of the present application, the step S1201 is an optional step. When the volume adjustment method provided by the present embodiment does not include this step S1201, the display device defaults to a preset position as the position of the focus frame, for example, the default focus frame is on the audio/video screen window.

In step S1202, the display device receives a volume adjustment instruction.

In the present embodiment, the volume adjustment instruction is used to instruct the display device to adjust the size of the sound played by the display device, such as turning the sound up, down, modulating the mute state, or switching from the mute state back to the previous state. The display device receives a volume adjustment instruction through the N chip, where the volume adjustment instruction may be an instruction sent by a remote controller carried by the display device, or an instruction sent by a remote controller application installed on an intelligent display device such as a mobile phone, and this embodiment is not limited thereto.

Step S1203, adjusting the volume of the audio/video signal corresponding to the window according to the volume adjustment instruction and the window in the display device display interface corresponding to the focus frame, where different windows correspond to different audio/video signals.

In some embodiments, the window display of the focus frame corresponding to the display interface includes the following two scenarios:

scene one: the focus frame is on the window corresponding to the audio and video picture.

If the audio/video signal corresponding to the window is directly received by the N chip from the outside of the display device (for example, a live television signal), the front-end gain of the audio/video signal corresponding to the window in the N chip is adjusted according to the volume adjusting instruction so as to adjust the volume of the audio/video signal corresponding to the window.

In this embodiment, it should be noted that the front-end gain refers to the adjustment amplitude of the signal before passing through the signal mixer, and is adjusted by the front-end gain unit. Correspondingly, the back-end gain refers to the adjustment amplitude of the signal after signal mixing, and is adjusted by the back-end gain unit.

Each chip system in the double-chip system comprises a front-end gain and a rear-end gain, and due to the connection of the N chip and the loudspeaker, when audio and video are displayed in multiple windows at the same time, audio streams in different audio and video correspond to different front-end gain units (which are from the A chip system and can be executed in the front-end gain unit of the A chip system and can also be executed in the rear-end gain unit of the A chip system), and audio signals processed by the front-end gain units are processed by the same rear-end gain unit in the N chip system after being mixed and superposed in the N chip system before being output by the loudspeaker.

In one example, when a live tv signal is accessed by HDMI 2.0, transmission paths of the live tv signal and the chat signal in the display device are as shown in fig. 9, and the display device adjusts the volume of the live tv signal by adjusting the front-end gain unit a of the N-chip.

If the audio/video signal corresponding to the window is directly received by the N chip from the A chip (such as a network television signal or a local audio/video signal), at least one of the front-end gain and the rear-end gain of the audio/video signal corresponding to the window in the A chip, the sound track volume of an application layer and the front-end gain of the audio/video signal corresponding to the window in the N chip is adjusted according to the volume adjusting instruction so as to adjust the volume of the audio/video signal corresponding to the window.

In one example, in combination with the transmission paths of the network television signal and the local audio/video signal in the display device shown in fig. 10, the display device realizes the individual adjustment of the sound of the network television or the local video by adjusting the front-end gain unit F of the a chip.

In another example, in conjunction with fig. 10, the display device realizes the individual adjustment of the sound of the network television or the local video by adjusting the back-end gain unit B of the a chip.

In another example, in conjunction with fig. 10, the display device realizes to separately adjust the sound of the network tv or the local video by adjusting the volume of the track volume, the stream volume, or the master volume track of the network/local tv signal in the a-chip.

In another example, in conjunction with fig. 10, the display device realizes the individual adjustment of the sound of the network television or the local video by adjusting the front-end gain unit B in the N chip.

Scene two: focus box on chat window

In this embodiment, when the focus frame is on the chat window, the control method of the chat sound is the same no matter whether the signal corresponding to the audio/video picture window is a live television signal, an internet television signal, or a local audio/video signal, which is specifically as follows:

when the area selected by the focus frame is all the chat windows (for example, fig. 14), the display device adjusts the front-end gain of the audio/video signals corresponding to all the chat windows in the N chip and/or adjusts the volume of the sound track corresponding to all the chat windows in the application layer of the N chip according to the volume adjustment instruction, so as to adjust the volume of the chat signals.

In an example, with reference to fig. 9 or fig. 10, the display device adjusts the volume of the audio and video signals corresponding to all chat windows by adjusting the front-end gain unit E of the N chips.

In another example, with reference to fig. 9 or fig. 10, the display device adjusts the volume of the audio/video signals corresponding to all chat windows by adjusting the volume of the stream volume or master volume track of the N chip. In this embodiment, the audio/video signal corresponding to the chat window may also be referred to as a chat signal.

It should be noted that, when only one chat object exists in the chat window and the selected area of the focus frame is all chat windows, the display device may adjust the volume of the chat signal in all chat windows by adjusting the volume of the track volume, the stream volume, or the master volume track in the N chip.

When the selected area of the focus frame is a dialog box (for example, fig. 16) of a specified chat object in the chat window, the display device adjusts the volume of the sound track corresponding to the dialog box in the application layer of the N-chip according to the volume adjustment instruction, so as to adjust the volume of the chat signal corresponding to the dialog box.

In one example, the display device adjusts the volume of a chat corresponding to the dialog box by adjusting the volume of a track volume track in the N-chip application layer corresponding to the dialog box.

In a more specific example of scenario two, user a (the logged-on user of the display device) receives a volume adjustment instruction while conducting a three-person video chat with user B and user C.

When the area selected by the focus frame in the chat window is all the chat windows, the display device adjusts the sound of the chat signals of the user B and the user C output by the display device by adjusting the volume of the stream volume or master volume tracks of the application layers corresponding to the user B and the user C and/or adjusting the front end gain unit E of the N chip.

When the area framed by the focus box in the chat window is only the dialog box of the user B, the display device adjusts the volume of the track volume track of the user B in the application layer so as to independently adjust the sound of the chat signal of the user B output by the display device.

In this embodiment, when the chat application, the network video application, and the local video application output signals to the N chip or the a chip, sound of at least one track is mixed and then output. For example, the chat application in the N-chip will mix the chat signal of user B in one track with the chat signal of user C in another track before outputting the mixed signals. Therefore, the display device can independently adjust the sound corresponding to the sound track by adjusting the sound track volume of the chat signal, the network television signal and the local audio-video signal in the application layer.

In this embodiment, it should be noted that the volume adjustment instruction sent by the remote controller is received by the N chip. Therefore, the N chip can directly adjust the volume of the display device according to the volume adjusting instruction. And after the N chip needs to send the volume adjustment information carried by the volume adjustment instruction to the A chip, the A chip can adjust the volume of the display device. In one example, the a chip and the N chip interact with each other in a communication manner as shown in fig. 11, the N chip sends a character string carrying volume adjustment information to the a chip through the second communication module, and the a chip receives the character string through the first communication module, analyzes and separates the volume adjustment information, and thereby adjusts a signal in the a chip.

In some embodiments, if the program source of the audio/video stream to be adjusted is an interface where the N chip is directly connected to the outside, the receiving module in the N chip directly sends the received adjustment instruction to the front-end sound processing unit in the N chip, if the program source of the audio/video stream is an interface where the N chip is connected to the a chip, the receiving module in the N chip sends the received adjustment instruction to the frame layer of the N chip, the frame layer of the N chip forwards the adjustment instruction to the frame layer of the a chip, and the frame layer of the a chip notifies the front-end sound processing unit and/or the rear-end sound processing unit of the a chip of processing the corresponding audio.

By the volume adjusting method provided by the embodiment, in the process of simultaneously playing audio and video and providing chat service, the display device can independently adjust audio and video sounds or chat sounds according to the volume adjusting instruction and the position of the focus frame, so that the user experience is improved.
