[0032] Figure 2 A schematic flow chart of an interactive method of an audio-visual system provided by the present invention is shown, the method comprising: S21, receiving device combination information sent by the screen end, and controlling the screen end to switch from the system sound card to the virtual sound card; wherein the device combination information includes information of the voice device used to form the whole-house wireless audio and video; S22, based on the virtual sound card and according to the device combination information, split the channel audio information of the screen-side audio and video content, and distribute the split channel audio information to the corresponding voice device.

[0033] It should be noted that the execution subject of this method is the TV background, and the step number "S2N" in this manual does not represent the order of the interactive method of the audio-visual system. Figure 3-Figure 4 The interactive method of the audio-visual system of the present invention is described.

[0034] Step S21, receiving the device combination information sent by the screen end, and controlling the screen end to switch from the system sound card to the virtual sound card; wherein the device combination information includes information of the voice device used to form the whole-house wireless audio and video.

[0035] In this embodiment, the device combination information is selected and combined by the screen end based on the received first device information; the first device information is the information of the voice device received by the screen end that is bound to the user account information and supports the combination.

[0036] It should be added that the TV combination speaker control application can be used to control the screen end to switch from the system sound card to the virtual sound card. In addition, the first device information is obtained by the Internet of Things (IOT) cloud platform based on the search request sent by the TV background, and is sent to the screen end through the TV background.

[0037] Specifically, refer to Figure 3 Before receiving the device combination information sent by the screen end, it includes: receiving the user account information sent by the screen end, and generating a search request according to the user account information; sending the search request to the Internet of Things IOT cloud platform, and receiving the first device information returned by the IOT cloud platform; sending the first device information to the screen end.

[0038] Specifically, the first device information is the voice device bound to the user account information searched by the IOT cloud platform based on the search request, and the voice device information that can support the combination is determined based on the version information, version compatibility information, system information and system compatibility information of the voice device obtained through the search.

[0039] In other words, after the IOT cloud platform receives the search request, it includes: based on the search request, searching for the voice device bound to the account information; based on the version information, version compatibility information, system information and system compatibility information of the voice device obtained by the search, determining whether each voice device supports the combination; based on the result of whether each voice device can support the combination, selecting the voice device information that can support the combination to obtain the first device information; and sending the first device information to the TV backend.

[0040] Furthermore, based on the version information, version compatibility information, system information and system compatibility information of the voice devices obtained through search, determine whether each voice device supports the combination, including: determining whether the versions and systems of each voice device are compatible based on the version information, version compatibility information, system information and system compatibility information of the voice devices obtained through search, and determining whether the corresponding voice device supports the combination based on the compatibility.

[0041] In an optional embodiment, before sending the first device information to the screen, it includes: determining whether each first device is in the same local area network according to the first device information, and filtering the first devices that are not in the same local area network. It should be noted that by filtering the first devices to eliminate voice devices that are not in the same local area network environment, it is avoided that the user account is bound to multiple voice devices in the local area network environment, so that the wireless audio and video system in the same house cannot be established, thereby improving the reliability of the wireless audio and video establishment.

[0042] Step S22, based on the virtual sound card and according to the device combination information, the channel audio information of the screen-side audio and video content is split, and the split channel audio information is distributed to the corresponding voice device.

[0043] In this embodiment, the channel audio information of the screen-side audio and video content is split according to the device combination information, and the split channel audio information is allocated to the corresponding voice device, including: determining the audio split number and the audio split type according to the number of each voice device in the device combination information, and splitting the channel audio information of the screen-side audio and video content according to the determined audio split number and the audio split type; and allocating the split channel audio information to the corresponding voice device according to the type and position of the voice device.

[0044] It should be added that the audio and video content on the screen can be obtained from the TV original sound application audio and video player in the TV background.

[0045] Furthermore, according to the number of voice devices in the device combination information, the number of audio splits and the type of audio splits are determined, including: if there are two voice devices, the number of audio splits can be three, and the audio split types include left channel and right channel; if there are four voice devices, the number of audio splits can be six, and the audio split types include left channel, right channel, left rear channel, right rear channel, center channel and bass channel. It should be noted that the more voice devices there are, the finer the splitting of channel audio information, thereby creating a more stereoscopic and surround audio effect from multiple directions, creating a more outstanding audio space effect, allowing users to feel richer audio space information, and adapting to more devices working together to provide a better audio experience.

[0046] In addition, refer to Figure 4, according to the type and location of the voice device, the split channel audio information is distributed to the corresponding voice device, including: using an audio distribution tool to distribute the split channel audio information to the corresponding voice device through a local area network. It should be noted that the audio and video system is built through the local area network and the screen and voice equipment are managed to achieve left and right channels and surround sound scenes on the basis of reducing wiring and simplifying installation, which is convenient for using existing smart devices to build an audio and video system, reducing the cost of purchasing and installing audio equipment, making scene building and movement more flexible, and facilitating the use of local area network to update software, so that users can expand the system and obtain new functions, ensuring the long-term availability and compatibility of the system.

[0047] It should be noted that when the split channel audio information is allocated to the corresponding voice device according to the type and position of the voice device, for the voice device with basic playback function and located in the front, the left channel, the right channel or the center channel is usually allocated; for example, the voice devices on the left and right sides in front of the TV can be allocated the left channel and the right channel respectively to provide the main front audio direction sense; and the voice device located in the middle of the TV is more suitable for allocating the center channel for playing the main audio information such as dialogue and lead singer; for the voice device with enhanced bass effect function, the bass channel may be allocated in combination with it; for example, a voice device with excellent bass performance ability may allocate the bass channel in combination with its common left or right channel to enhance the low-frequency effect of the audio and create a more shocking audio atmosphere; for the voice device located in the rear, such as behind the user, the left rear channel and the right rear channel may be allocated to simulate the sound from the rear, enhance the surround and spatial sense of the audio, and make the user feel that the sound comes from all directions.

[0048] For example, if a TV is combined with two audio devices, the virtual sound card will split the audio information of the audio and video content into left and right channels. The TV plays all channel content, one audio device plays the left channel content, and one audio device plays the right channel content.

[0049] For another example, if a TV is combined with four audio devices, the virtual sound card will split the audio information of the audio and video content into left channel, right channel, left rear channel, right rear channel, center channel, and bass channel. The TV plays the center channel, left channel, and right channel, one audio device plays the left channel + bass channel, one audio device plays the right channel + bass channel, one audio device plays the left rear channel, and one audio device plays the rear channel.

[0050] In an optional embodiment, after the split channel audio information is distributed to the corresponding voice device, it includes: displaying the audio and video system obtained after the split channel audio information is distributed to the corresponding voice device on the screen.

[0051] To summarize, the embodiment of the present invention receives the device combination information sent by the screen end, controls the screen end to switch to a virtual sound card, and uses the virtual sound card to split the channel audio information of the audio and video content of the screen end, and distributes the split channel audio information to each voice device in the device combination information to create a more outstanding audio space effect, so that the user can feel richer audio space information, adapt to more devices working together to provide a better audio experience, and is suitable for existing smart devices to form an audio and video system, reduce the cost of purchasing and installing audio, and make scene construction and movement more flexible.
