Description

Technical Field

[0001] The utility model relates to the technical field of video playback, in particular to an LED HUB integrated video control system. Background Art

[0002] LED display systems are currently widely used in billboards, stage performances, conference presentations, and other fields. One of their core components is the LED hub (integrated control center). Traditional LED hub systems typically rely on external professional video control equipment to transmit audio and video signals from the signal source to the main control device via standard video interfaces (such as HDMI) and high-definition video cables. The main control device then encodes the video signal into a network stream signal in H.264 / H.265 format and transmits it via a network cable to the LED hub. The LED hub then uses a decoding device to decode the network stream signal into RGB signals, ultimately driving the LED display screen for display.

[0003] However, the existing LED HUB system has the following major problems:

[0004] Limited signal transmission distance: Traditional high-definition video cables have a short transmission distance, which makes it difficult to meet the needs of large-scale or long-distance application scenarios, limiting the application scope of LED display systems.

[0005] Single signal type: The existing system mainly supports the transmission of video signals and cannot simultaneously transmit audio signals and multiple control signals (such as IR control and RS232 / 485 control signals), which limits the system's functional expansion and application flexibility.

[0006] High system complexity: Traditional LED HUB systems rely on multiple external devices and a large number of network cables for signal transmission, which increases the complexity and maintenance difficulty of the system and is not conducive to rapid deployment and management.

[0007] Low bandwidth and transmission efficiency: Due to the use of standard video interfaces and network cables for signal transmission, the overall bandwidth is limited and cannot efficiently support high-resolution video and simultaneous transmission of multiple signals, affecting display effects and system performance.

[0008] In summary, the problems existing in the prior art need to be solved urgently. Utility Model Content

Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0038] In order to solve the problems in the prior art, the present invention proposes an LED HUB integrated video control system. The LED HUB integrated video control system is described below. Figure 1 As shown, including but not limited to the following modules:

[0039] Network decoding module, MPO optical port module, video control module and video display module;

[0040] The network decoding module is used to receive and decode H.264 / H.265 network stream signals and convert them into standard HDMI signals;

[0041] The MPO optical port module is used to receive composite optical signals and output video signals, audio signals, IR control signals and RS232 / 485 control signals after decoding;

[0042] The video control module is used to convert the signal input by the network decoding module or the MPO optical port module into an RGB signal and transmit it to the video display module;

[0043] The video display module is used to realize picture display according to the RGB signal.

[0044] The network decoding module receives network streaming signals in H.264 / H.265 format. It receives streaming video signals from a remote location via a network interface and decodes them using a built-in H.264 / H.265 decoding chip. The decoded signal is converted to a standard HDMI signal, compatible with most commercially available display devices. To ensure a stable connection, the network decoding module connects to other modules via a 120-pin high-density connector for signal transmission and power supply.

[0045] The MPO optical port module receives composite optical signals. A built-in composite signal decoding chip separates the optical signals into multiple signal types, including video, audio, IR control, and RS232 / 485 control signals. A conversion chip converts the separated signals into different formats, making them compatible with LED display control systems. The use of the MPO optical port module significantly extends signal transmission distances and supports the simultaneous transmission of multiple control signals, enhancing system versatility.

[0046] The video control module, the system's core processing unit, is responsible for converting HDMI signals input from the network decoding module or MPO optical port module into RGB signals. Specifically, the video control module uses a built-in video switching chip to select and switch between multiple HDMI signal sources. The selected HDMI signals are then transmitted to the conversion chip, completing the conversion from HDMI to RGB. The video control module is also equipped with a microcontroller unit (MCU), which controls the signal selection of the video switching chip, ensuring seamless switching between different signal sources.

[0047] The video display module receives RGB signals from the video control module and displays images based on these signals. This module is compatible with various LED displays and produces high-quality images based on the received RGB signals. The video display module connects to other modules via a 120-pin high-density connector, enabling simultaneous data and power transmission.

[0048] As a further optional embodiment, the network decoding module includes an H.264 / H.265 decoding chip and a 120-pin high-density connector;

[0049] The H.264 / H.265 decoding chip is used to decode the received network stream signal;

[0050] The 120-pin high-density socket is used to connect with other modules of the LED HUB integrated video control system.

[0051] The network decoding module features a built-in H.264 / H.265 decoder chip specifically designed to receive and decode H.264 / H.265 video streams transmitted over the network. This chip efficiently processes high-quality video compression standards and converts received network streams into standard HDMI signals for easy processing by subsequent modules. The high-performance H.264 / H.265 decoder chip ensures real-time decoding of video signals, ensuring smooth and clear video playback.

[0052] The network decoding module connects to other modules in the LED HUB integrated video control system via a 120-pin high-density connector. This connector not only transmits the decoded HDMI signal but also provides power and other control signals. The high-density design of the 120-pin high-density connector effectively reduces the physical space required between modules while ensuring high-speed and stable data transmission.

[0053] As a further optional embodiment, the MPO optical port module includes a composite signal decoding chip and a conversion chip;

[0054] The composite signal decoding chip is used to separate the received composite optical signal into a video signal, an audio signal, an IR control signal and an RS232 / 485 control signal;

[0055] The conversion chip is used to convert the separated signal into a format suitable for the LED control system.

[0056] The MPO optical port module incorporates a built-in composite signal decoding chip, which receives and separates composite optical signals transmitted through the MPO fiber. Composite optical signals typically contain multiple types of information, and the composite signal decoding chip separates the video, audio, IR control, and RS232 / 485 control signals. This process ensures that each signal is transmitted and processed separately within the system, guaranteeing signal validity and compatibility.

[0057] After the composite signal is decoded, the various signals still need to be converted into a signal format compatible with the LED control system. The conversion chip is responsible for converting the separated signals to ensure that the output signals can be correctly received and processed by the video control module in the LED hub system. Specifically, the video signal is converted into a format suitable for RGB display, and the control signal is converted into a control signal compatible with the corresponding protocol to achieve seamless compatibility with other modules in the system.

[0058] As a further optional embodiment, the video control module includes: a video switching chip, a conversion chip and a microcontroller unit;

[0059] The video switching chip is used to select and switch multiple HDMI signal sources;

[0060] The conversion chip is used to convert the selected HDMI signal into an RGB signal;

[0061] The microcontroller unit is used to control the signal selection of the video switching chip.

[0062] The video control module includes a built-in video switching chip, which is used to select and switch between multiple HDMI signal sources. The system can receive multiple HDMI signals from different input sources, and the video switching chip selects one of these signals as the output signal based on the system configuration or user needs. This function enables the system to flexibly handle switching between multiple video sources, making it suitable for video display needs in various scenarios.

[0063] The HDMI signal selected by the video switching chip is transmitted to the conversion chip, which converts it into an RGB signal suitable for the LED display system. HDMI signals are typically in a digital video format, while LED display systems require RGB video signals. The conversion chip completes this format conversion process, enabling the display system to correctly display the corresponding video content.

[0064] To enable intelligent switching of multiple HDMI signals, the video control module also includes a microcontroller unit (MCU). This unit controls the signal selection function of the video switching chip through programming. Based on pre-set system logic or user input, the MCU can determine and switch the current HDMI signal source in real time, ensuring the system can automatically or manually switch signal sources, enhancing operational convenience and flexibility.

[0065] As a further optional embodiment, the network decoding module, MPO optical port module, video control module and video display module transmit and connect data and power through the 120-pin high-density socket.

[0066] This 120-pin, high-density connector enables high-speed data transmission between modules. Through this connector, the HDMI signal decoded by the network decoding module and the various signals decoded by the MPO optical port module (video, audio, IR control, and RS232 / 485 control) are transmitted to the video control module. The video control module then converts the signal into RGB and transmits it to the video display module for proper display. This high-density connector ensures stable and efficient signal transmission, making it suitable for large-scale data flow transmission.

[0067] Furthermore, a 120-pin high-density connector provides power transmission between all modules in the system. The network decoding module, MPO optical port module, video control module, and video display module all receive a stable power supply through this connector, ensuring the proper functioning of all components within the system. This unified power transmission design reduces redundant cables and power connectors, improving system integration and ease of use.

[0068] As a further optional embodiment, the video control module further includes: a sending module and a receiving module;

[0069] The sending module is used to output RGB signals;

[0070] The receiving module is used to receive standard HDMI signals.

[0071] The sending module is used to output the RGB signals processed by the video control module to the subsequent display device. Specifically, after the video control module converts the input HDMI signal into RGB signals through the video switching chip and the conversion chip, the sending module is responsible for transmitting these RGB signals to the video display module for image display.

[0072] The design of the sending module can ensure that the RGB signal remains stable during transmission and avoid image quality degradation due to signal interference or loss.

[0073] The receiving module is used to receive standard HDMI signals, regardless of whether the signal is output from the network decoding module or the MPO optical port module. After the receiving module performs preliminary processing on the received HDMI signal, it transmits it to other parts of the video control module for further signal conversion and processing.

[0074] Through the design of the receiving module, the system can easily integrate multiple HDMI signals from different sources, providing a basis for unified processing and control of video signals.

[0075] As a further optional embodiment, the network decoding module further includes a power management unit;

[0076] The power management unit is used to provide stable power to the decoding chip and other components, and is equipped with a heat sink to ensure temperature control of the decoding chip during operation.

[0077] The power management unit's primary function is to provide a stable power supply to the H.264 / H.265 decoding chip and other components in the network decoding module. It ensures that all components receive the required voltage and current during operation to maintain normal system operation and efficient performance.

[0078] To ensure the stability of the power supply, the power management unit adopts multiple power regulation and monitoring technologies, including overvoltage protection, undervoltage protection and short-circuit protection functions to ensure the reliability and safety of the power supply.

[0079] The power management unit is also equipped with a heat sink to effectively control the temperature of the decoding chip during operation. The heat sink is designed to provide good thermal conductivity to reduce the heat generated by the decoding chip during high load operation, thereby preventing performance degradation or device damage due to overheating.

[0080] The following describes the principles of each module:

[0081] Embodiments of the network decoding module, such as Figure 2 shown:

[0082] The circuit diagram contains a standard HDMI input interface for receiving HDMI signals from external devices (such as computers, cameras, etc.). The RX+ and RX- pins of the HDMI interface are used to receive differential signals from the HDMI device. These signals carry video and audio data, which are transmitted to the decoding chip for further processing. The power pins of the HDMI interface provide the required stable voltage for the HDMI circuit, which is generally achieved through a power management unit.

[0083] When an external device (such as a computer, video player, etc.) inputs a signal through an HDMI cable into the HDMI interface, the RX+ and RX- pins receive the differential signals and transmit them to the decoding chip. The decoding chip processes the HDMI signal and sends it to the video switching module. This module converts the HDMI signal into a signal that matches the RGB format. The power pins ensure that the HDMI interface always maintains a stable power supply during transmission, preventing signal distortion or loss.

[0084] Embodiments of the MPO optical port module, such as Figure 3 shown,

[0085] The SFP (Small Form-factor Pluggable) optical fiber module is used to receive composite signals from optical fiber transmission, including video, audio, and control signals (such as RS232 / 485 signals). The receive (RD+) and transmit (TD+) pins within the SFP module are used to transmit optical signals. SFP_RD+ receives optical fiber signals, and SFP_TD+ is used to transmit signals to remote devices. The received optical signals are transmitted to a composite signal decoding chip, which decodes and separates the signals into video, audio, IR control signals, and RS232 / 485 control signals.

[0086] The SFP module receives composite signals through optical fibers, and the optical signals enter the composite signal decoding chip through SFP_RD+. The decoding chip decodes the received composite signals, separating out video signals for display, audio signals for audio output, and control signals (RS232 / 485, IR signals) for remote device control.

[0087] The decoded signals are transmitted to the video control module and further processed or converted.

[0088] The transmitting end (SFP_TD+) is used to transmit optical signals from the system to remote devices, completing bidirectional data transmission.

[0089] Embodiments of the video control module, such as Figure 4 shown,

[0090] The video switch chip receives multiple HDMI signals from the network decoding module and the MPO optical port module and selects the signal source to be processed and output. The selected HDMI signal is then transmitted to the conversion chip, which converts the HDMI signal into RGB signals suitable for the LED display. The MCU controls the video switch chip, determines the current signal source to be processed, and implements signal switching and selection.

[0091] When multiple HDMI signals are input to the video control module, the video switching chip, under the control of the MCU, selects one signal for processing. The selected HDMI signal is then transmitted to the conversion chip, which converts the HDMI signal into an RGB signal suitable for the LED display. This RGB signal is transmitted to the video display module via a 120-pin high-density connector for proper display. The MCU is responsible for logical control of the entire signal switching process, selecting different video sources based on user input or system configuration.

Based on this understanding, the essence of the above technical solution, or the portion that contributes to the prior art, can be embodied in the form of a software product.
