[0022] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Example 1

[0024] Please see Figure 1-4 This utility model is an integrated system host for controlling a large screen display, including a backplane module. A PCIe slot is installed on the inner wall of the backplane module. A signal processing module is plugged into the interface of the PCIe slot. The signal processing module includes a first modular board, a second modular board, and a third modular board. Each of the first, second, and third modular boards includes a main chip. The main chip is bidirectionally electrically connected to a first network chip, DDR storage, and Flash storage. The input end of the main chip is unidirectionally electrically connected to an HDMI input end and a power conversion module. The network chip is bidirectionally electrically connected to a network signal metal finger connector.

[0025] Specifically: The first, second, and third modular boards support 4K decoding and encoding, and support multiple network transmission protocols and multiple bitstream transmission methods. They provide support for network audio and video decoding output, large-scale video wall decoding, splicing and splitting display services, etc. Through modular design, they can be combined and installed in the backplane modules according to user needs to form an integrated system host. Utilizing the Linux operating system installed in the signal processing module, along with the WEB operation interface on the control terminal, corresponding control commands can be sent to the integrated system host via the network based on the operation of the WEB interface. This allows for common operations such as splitting, merging, splicing, picture-in-picture, and roaming of the display screen. Each module's HDMI output port supports... The system features 36 windows, all of which can span multiple screens, roam, freely scale, and be arbitrarily overlaid. It also determines the primary and secondary relationships between multiple signal processing modules based on user needs. The primary module acts as a support carrier, maintaining communication between secondary modules and the primary module's intranet. If the primary module fails, the secondary module can be directly installed in the primary module's position. Following the primary-secondary assembly relationship and the number of modules, the system uses an internal backplane integrated network switch and PCIe slots to connect the modules. This allows each secondary module to communicate with the primary module via the intranet on the backplane. The system installs the required signal processing modules, reserving connection space and structures to facilitate temporary module additions or system expansion.

The backplane module includes a network switching module and a power module, both of which are bidirectionally electrically connected to the PCIe slot. The outputs of the backplane module are equipped with USB and network interfaces, respectively. The backplane module also has a unidirectional electrical connection to a power input interface and a power switch. Furthermore, it has unidirectional electrical connections to a microphone, speakers, network devices, and video input sources. The outputs of the network devices are unidirectionally electrically connected to a network video signal source and a web page control device. The backplane module has bidirectional electrical connections to a keyboard, mouse, and keyboard controller.

The metal finger connector enables network signal exchange. The power module supplies power to the signal processing module, ensuring its proper operation. USB and network interfaces allow the backplane module to connect to operating devices and provide network connectivity, facilitating remote operation of the entire system host via a web interface. Microphone, speakers, network devices, and video input sources handle various signal input operations. The network device inputs video signals and web-based control devices into the signal processing module. Users can directly use a USB keyboard and mouse to control and adjust interface transparency and related software settings via the local interface. The keyboard controller can be used to operate the integrated system host and adjust camera lenses.

[0029] The working principle of this invention is as follows: The system host works collaboratively with the backplane module through a hardware modular design of the signal processing module. Through the first, second, and third modular boards, it supports 4K decoding, 4K encoding, and various network transmission protocols. Users insert HDMI input / output, audio processing, network switching, and other functional modules into the backplane PCIe slots according to their actual needs. The main module manages the communication and data interaction of each secondary module through the internal network switching circuit of the backplane module. When the main module fails, the secondary module can quickly replace it and take over the control functions, achieving high fault tolerance and maintainability of the system. The software consists of a Linux system running in the signal processing module and a WEB operating platform. Users can log in to the WEB interface via PC, mobile phone, or tablet. The system provides real-time preview of video sources and performs cross-screen splicing, image roaming, window scaling, and scene saving operations on the large-screen display area. Control commands are transmitted to the system host via the network. The main module coordinates various functional modules to perform signal processing and scheduling, audio synchronization processing, embedding / de-embedding, and switching tasks. The first and second network chips connect to devices such as cameras and hard disk recorders via gigabit Ethernet ports to acquire video streams, convert HDMI input signals into digital streams for transmission to the display end, decode the network video stream, and output it to the large screen. All operations support multi-user permission management and data import / export, ensuring system security and scene adaptation flexibility.
