[0001] This utility model relates to the field of audio and video signal processing equipment technology, and in particular to a low-link-interference 12-input 12-output seamless switching signal processor. Background Technology

[0002] In modern audio-visual system applications, with the development of digitalization and intelligence, the requirements for signal processing are increasing, especially in scenarios such as large conference rooms, monitoring centers, and multimedia exhibition halls, where it is necessary to flexibly switch and process multiple audio and video signals to meet different display and playback needs.

[0003] In existing technologies, two devices, a matrix and a splicing processor, are typically used to meet the relevant requirements. In this approach, the transmission between devices generally uses HDMI cables. However, this transmission method has significant drawbacks in complex application scenarios: Firstly, its transmission quality is highly dependent on the anti-interference capability of the cable. When there is electromagnetic interference in the environment, it can easily lead to signal distortion, stuttering, or even interruption, resulting in poor stability and severely affecting the playback effect of audio and video. Secondly, using two devices to meet the requirements not only increases the purchase cost of the equipment but also makes the system structure more complex, increasing the difficulty of installation, debugging, and maintenance.

[0004] Therefore, it is necessary to provide a low-link-interference 12-in-12-out seamless switching signal processor to solve the above-mentioned technical problems. Utility Model Content

[0005] This invention provides a seamless 12-input 12-output signal processor with low link interference, which solves the problems of existing solutions requiring two devices to work together, relying on HDMI cables for transmission which is susceptible to interference, having a complex system structure, high cost, and difficult maintenance.

[0006] To solve the above-mentioned technical problems, this utility model provides a low-link-interference 12-input 12-output seamless switching signal processor, comprising: The system includes multiple input system boards, a first high-speed connector, a first high-speed connector slot, a second high-speed connector slot, a matrix system board, a second high-speed connector, multiple output system boards, a control connection cable, and a control system board.

[0008] Preferably, there are three input system boards and three output system boards.

[0009] Preferably, the low-link-interference seamless switching signal processor further includes multiple mounting components and two support components, with the two support components disposed on the inner side of the housing and the multiple mounting components respectively disposed on the inner side of the two support components.

[0010] Preferably, both of the support components include a support frame, multiple sliding grooves and multiple threaded holes.

It integrates multiple input system boards, a first high-speed connector, a first high-speed connector slot, a second high-speed connector slot, a matrix system board, a second high-speed connector, an output system board, and a control system board. In operation, it combines the functions of a traditional matrix and splicing processor into one unit. The matrix system board directly receives the 12 signals from the input system boards and distributes them to the 12 outputs of the output system boards, eliminating the need for additional equipment.

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0017] First Embodiment

[0018] Please refer to the following: Figure 1 , Figure 2 ,in, Figure 1 A schematic diagram of the structure of a first embodiment of a low-link-interference 12-input 12-output seamless switching signal processor provided by this utility model; Figure 2 for Figure 1 The diagram shows the internal structure of the shell.

[0019] A low-link-interference 12-input 12-output seamless switching signal processor includes: multiple input system boards 1, a first high-speed connector 2, a first high-speed connector slot 3, a second high-speed connector slot 4, a matrix system board 5, a second high-speed connector 6, multiple output system boards 7, a control connection cable 8, and a control system board 9. The first high-speed connector 2 is electrically connected to the multiple input system boards 1. The first high-speed connector slot 3 and the second high-speed connector slot 4 are both electrically connected to the matrix system board 5. The second high-speed connector 6 is electrically connected to the multiple output system boards 7. The two ends of the control connection cable 8 are electrically connected to the control system board 9 and the matrix system board 5, respectively. The first high-speed connector 2 is inserted into the inner side of the first high-speed connector slot 3, and the second high-speed connector 6 is inserted into the inner side of the second high-speed connector slot 4.

[0020] The outer surfaces of the plurality of input system boards 1, the first high-speed connector 2, the first high-speed connector slot 3, the second high-speed connector slot 4, the matrix system board 5, the second high-speed connector 6, the plurality of output system boards 7, the control connection line 8, and the control system board 9 are all provided with housings 10.

[0021] Both the input system board 1 and the output system board 7 are provided in threes.

[0022] Input system board 1: Audio and video signal sources are connected to input system board 1 through the HDMI interface and Phoenix terminal. The ASIC in input system board 1 is responsible for processing video and audio. The MCU is responsible for controlling the configuration of the ASIC and also parses the parameter information of the video signal source to provide to the control system board. Finally, the input chipset processes multiple (up to 12) independent input signal sources and sends them to matrix system board 5 through the first high-speed connector 2. Matrix system board 5: Matrix system board 5 receives audio and video signal sources from input system board 1 through the first high-speed connector slot 3. It sends the video signal to the ASIC to handle the connection of the signal channels and sends the audio signal source to the FPGA through matrix system board 5 to handle arbitrary allocation of audio channels. Finally, the signal is sent out to output system board 7 through the second high-speed connector slot 4. The core part is to use the second high-speed connector 6 to connect matrix input system board 5, output system board 7 and control system board 9 to achieve arbitrary interaction and allocation of signals without the need to connect complicated signal lines and control lines. Finally, the matrix chipset receives the signal from input system board 1 and can process any independent signal source and allocate it to any channel to provide to output system board 7. Output system board 7: The output system board 7 receives audio and video signal sources from the second high-speed connector 6. The ASIC is responsible for receiving signals from the matrix system board 5, processing video and audio signals, distributing them according to the set parameter information, and finally using the output chipset to transmit the signal from the output system board 7 to the display end through the HDMI connector and Phoenix connector. Control system board 9: The MCU is responsible for receiving control signals through the ports of the control system board 9 (TYPE-C interface, network port, RS232 port, IR port), processing them, and then outputting control commands through the control connection line 8 to complete the parameter setting of the whole machine's input system / output system / matrix system, thereby achieving signal channel transmission and allocation and signal processing settings; There are three input system boards 1 and three output system boards 7. Each input system board 1 has four HDMI input ports, and each output system board 7 has four HDMI output ports.

[0023] The working principle of the low-link-interference 12-input 12-output seamless switching signal processor provided by this utility model is as follows: External audio and video signal sources are connected to three input system boards 1 (each board has 4 inputs, for a total of 12) via HDMI or Phoenix connectors. After the signals enter the input system boards 1, the ASIC chip preprocesses the audio and video signals (such as format conversion and noise reduction), and the MCU chip simultaneously parses the signal parameters (resolution, frame rate, etc.) and uploads them to the control system board 9. The 12 preprocessed signals are transmitted to the matrix system board 5 via a hard connection between the first high-speed connector 2 and the first high-speed connector slot 3, replacing the traditional HDMI cable, avoiding signal distortion caused by electromagnetic interference, and achieving low link interference transmission. After receiving 12 input signals, the matrix system board 5 uses its internal ASIC chip to process video channel links and its FPGA chip to arbitrarily allocate audio channels. According to the instructions of the control system board 9 (such as switching instructions sent by the user via TYPE-C, Ethernet, or RS232), it can seamlessly allocate any one or more input signals to the target output channel. The switching process is smooth without black screen or lag, achieving a "seamless switching" effect. The processed signals are transmitted to the three output system boards 7 (each board has 4 outputs, for a total of 12) through the second high-speed connector slot 4 and the second high-speed connector 6. After receiving the matrix signal, the ASIC chip of the output system board 7 optimizes the audio and video signal according to preset parameters (such as brightness and contrast), and finally transmits it to the display device (such as video wall or projector) through HDMI or Phoenix connector. The control system board 9 adjusts the parameters of the input system, matrix system and output system in real time through the control connection cable 8, such as adjusting the signal switching logic and setting the output resolution. At the same time, it receives infrared remote control commands through the IR interface to realize multi-mode operation and adapt to different usage scenarios.

[0024] Compared with related technologies, the low-link-interference 12-input 12-output seamless switching signal processor provided by this utility model has the following advantages: By employing multiple input system boards 1, first high-speed connector 2, first high-speed connector slot 3, second high-speed connector slot 4, matrix system board 5, second high-speed connector 6, output system board 7, and control system board 9 in cooperation, the system integrates the functions of two devices—a traditional matrix and splicing processor—into one unit. The matrix system board 5 directly receives the 12 signals from the input system board 1 and distributes them to the 12 outputs of the output system board 7, eliminating the need for additional equipment. This significantly simplifies the system structure and reduces purchase costs and maintenance complexity. Furthermore, the hard connection between the input system board 1 and the first high-speed connector slot 3, and the hard connection between the output system board 7 and the second high-speed connector slot 4, avoids the limitations of insufficient anti-interference capability of cables, effectively resists electromagnetic interference, achieves low-link interference transmission, and enhances the audio and video playback effect.

The two support components 12 are disposed on the inner side of the housing 10, and the multiple mounting components 11 are respectively disposed on the inner side of the two support components 12.

[0031] There are two support frames 121. Each support frame 121 has six sliding grooves 122 on its inner side and three mounting components 11 on its inner side for mounting three input system boards 1 and three output system boards 7. When in use, the slide plate 113 is adapted to the sliding grooves 122, so that the user can easily remove the mounting components 11 with the boards installed from the inner side of the housing 10.

[0032] The working principle of the low-link-interference 12-input 12-output seamless switching signal processor provided by this utility model is as follows: Install the three input system boards 1 and the three output system boards 7 on the back of the mounting plate 111. Then, align the sliding plate 113 on the back of the mounting plate 111 of the mounting assembly 11 with the groove 122 on the inner side of the support frame 121 of the support assembly 12. Slide the mounting plate 111 along the groove 122 until the boards move to the target position. Then, tighten the mounting screws 112 at both ends of the mounting plate 111 so that the screws are threaded into the threaded holes 123 on the front of the support frame 121. Fix the mounting plate by the cooperation of the mounting screws 112 and the threaded holes 123, and then firmly fix the boards in the housing 10.

[0033] Compared with related technologies, the low-link-interference 12-input 12-output seamless switching signal processor provided by this utility model has the following advantages: With the cooperation of the mounting component 11 and the support component 12, when in use, the three input system boards 1 and the three output system boards 7 are respectively mounted on the multiple mounting components 11.
