[0033] The inventors, through analysis of existing technologies, discovered that while the demand for simultaneous multi-platform live streaming is growing among businesses, current solutions have the following shortcomings: First, while distributing live stream signals to multiple platforms using virtual camera technology is low-cost, it requires high-performance computers and carries the risk of being flagged as a fake live stream by platforms, impacting account traffic and compliance. Furthermore, virtual cameras are unstable, prone to disconnections and configuration loss, affecting live stream stability. Second, configuring separate cameras and capture cards for each platform is a common practice, but this method is costly, complex in terms of equipment connection and operation, and cannot achieve multi-camera live streaming, limiting the richness and professionalism of the live stream content.

[0035] In the embodiments of this application, addressing the problems of "complex operation, unstable equipment, and high cost" in the prior art for "multi-platform live broadcasting," the application provides a solution for a multi-platform live broadcast acquisition system with multiple signal acquisition components.

This enables low-cost multi-platform live streaming without the need for complex cable connections and parameter settings, reducing the difficulty of operation. The live streaming platform recognizes the actual hardware acquisition modules, avoiding misjudgment as fake live streaming due to the use of virtual cameras, thus improving the stability of the live streaming.

[0036] The following will further describe a multi-platform live streaming acquisition system in this exemplary embodiment.

[0039] In one specific embodiment, the original live broadcast signal from the source signal output component is input to the signal processing component 1. After processing by the signal processing component 1, it is output to multiple signal acquisition components. The multiple signal acquisition components output multiple independent and identical live broadcast signals respectively. The signal merging component merges the above signals and inputs them to the platform distribution component 2. The platform distribution component 2 generates multiple identical display units. The display screens of the multiple display units are identical and can be directly used by live broadcast tools on multiple platforms.

When live streaming is performed, the signal processing component 1 receives and processes the live stream signal output by the source signal output component and inputs the live stream signal to the signal acquisition components. The four signal acquisition components respectively acquire and copy the live stream signal, outputting four live stream signals. The signal merging components input the four signals to the platform distribution component 2.

The two signal acquisition components respectively acquire and copy the live stream signal, outputting two live stream signals. The signal merging component inputs the above signals to the platform distribution component 2, which generates two identical display units and transmits the two display units to two different live streaming platforms for synchronous live streaming.

[0043] It is also understandable that the number of signal acquisition components and signal merging components can be flexibly changed according to the actual needs of live streaming users, adapting flexibly to different needs, which can meet the needs of multi-platform live streaming and optimize the actual needs of hardware resources.

[0044] In one embodiment of this application, the source signal output component includes: a video signal output module connected to the signal processing component 1, used to output the original video signal and input the video signal to the signal processing component 1; and an audio signal output module connected to the signal processing component 1, used to output the original audio signal and input the audio signal to the signal processing component 1; wherein the video signal output module includes at least one camera; and the audio signal output module includes at least one earphone, microphone, or pickup.

[0048] In one specific embodiment, the audio signal output module may include multiple audio signal sources, such as audio signals output from a microphone, headphones, or pickup, audio signals output from a wireless Bluetooth device, and audio signals output from live music. After the audio signals are mixed and noise-reduced by the audio processor, they can be synchronously acquired and transmitted to the platform distribution component 2 along with the video signals to realize the multi-audio input live streaming function.

[0049] In one embodiment of this application, the signal processing component 1 includes: a video signal processing module connected to a plurality of signal acquisition modules, used to process raw video signals and input video signals to the plurality of signal acquisition modules; and an audio signal processing module connected to a plurality of signal acquisition modules, used to process raw audio signals and input audio signals to the plurality of signal acquisition modules; wherein the video signal processing module includes an HDMI matrix switch, and the audio signal processing module includes an audio processor.

[0050] It's important to note that HDMI is a fully digital video and audio transmission interface that can transmit uncompressed audio and video signals. An HDMI matrix switch is a device used to switch signals between multiple HDMI inputs and outputs, primarily for switching multiple HDMI signal sources to multiple HDMI displays, supporting the transmission of high-definition video and audio signals. Its main functions include seamless switching, multi-screen splicing, and local area network control.

[0051] In one specific embodiment, the HDMI signal from the camera is input to an HDMI matrix switch, selected, and then distributed to multiple signal acquisition components. These components acquire, copy, and transmit the signals to a signal merging component. The audio signal, after noise reduction and mixing by an audio processor, is also transmitted to the signal merging component and input synchronously with the video signal to the platform distribution component 2.

[0061] In one embodiment of this application, the HDMI matrix switch includes four HDMI input ports.

[0062] In one specific embodiment, the HDMI matrix switch includes four HDMI input ports, which can respectively receive HDMI signals output by up to four video signal output devices. After being processed by the switch selection, the signals are output to the signal acquisition module to realize multi-camera broadcasting function.

[0063] It should also be noted that this application also provides a multi-platform live streaming capture card product, which has a built-in signal processing component 1, multiple signal acquisition components and multiple signal splitting components, or the multiple signal splitting components can be changed from built-in to external, while other components remain unchanged.

[0064] The multi-platform live streaming acquisition system provided in this application enables simultaneous live streaming across multiple platforms at a low hardware cost, while also offering high reliability and convenience. By setting up multiple signal acquisition devices, low-cost multi-platform live streaming is achieved, requiring only a minimum of one set of video signal input modules (e.g., one camera) to support simultaneous streaming on up to four platforms. By setting up an audio signal processing module and connecting it to multiple signal acquisition devices, noise reduction and / or mixing of the input audio data can be performed, eliminating the need for additional mixing equipment for multi-source live streaming. The modular design enables plug-and-play functionality, eliminating the need for cumbersome parameter configuration and reducing the possibility of cable usage and connection failures, thereby improving live streaming stability. Furthermore, the live streaming platform recognizes only the actual hardware acquisition modules, avoiding misjudgments of fake live streams due to the use of virtual cameras.
