Description

Technical Field

[0001] The invention relates to the field of multimedia data transmission, and in particular to a modular multimedia OPS playback box. Background Art

[0002] OPS (Open Pluggable Specification) is a computing module plug-in format that can be used to add computing power to flat panel displays. The format was first announced by NEC, Intel, and Microsoft in 2010. OPS-formatted computing modules can run on Intel and ARM-based CPUs, running operating systems including Microsoft Windows and Google Android.

[0003] HDBaseT is a high-definition digital display interface that achieves an integrated connection between high-definition video sources and remote displays through a 100-meter / 328-foot CAT5e / 6 cable, providing uncompressed high-definition 4k video, audio, Ethernet, control signals, and up to 100 watts of power. HDBaseT uses an 8P8C (RJ45) connector, commonly known as a crystal head or Ethernet connector. It does not redesign a new interface like HDMI and Display Port, and the transmission medium uses a common network cable. In addition to providing video signal transmission functions, the HDBaseT standard also has network connection and Ethernet power (POE) functions.

[0004] Due to the strong computing power of OPS, it is very easy to replace the computing module when a failure occurs, thereby reducing downtime and maintenance costs; HDBaseT supports a maximum transmission rate of 20Gbps and can perfectly support FULL 3D and 4K x 2K video formats.

[0005] For example, the Chinese utility model patent with announcement number CN218958965U discloses a pluggable OPS host, LED display system and LED display screen, including an LED display screen, which has a accommodating portion in the non-display area; an LED display mainboard is arranged in the accommodating portion; an OPS adapter board and an Android board electrically connected are arranged on the LED display mainboard; the pluggable OPS host is placed in the accommodating portion and is pluggably electrically connected to the OPS adapter board.

[0006] The Chinese invention patent with announcement number CN104135643A discloses a method and device for long-distance high-definition transmission. The method obtains a first signal through at least one video interface; converts the first signal into a digital signal, and converts the digital signal into a digital signal of the HDBaseT protocol; and sends the digital signal of the HDBaseT protocol to a remote HDBaseT display device, so that according to the different types (digital or analog) and resolutions of video signals input from different interfaces, multiple video signals can be collected simultaneously through flexible application configuration. For high-definition video signals, the high-definition transmission technology HDBaseT can be used to transmit uncompressed and encoded video signals over long distances. At the remote end, the HDBaseT protocol signal is restored to a video signal through an HDBaseT receiving device and then input to the display device through an HDMI interface for display.

[0007] In the existing multimedia field, for the live broadcast function of audio and video, the video data is basically compressed, which cannot fully present the image details in high-definition application scenarios, and cannot meet the requirements of clear images for application scenarios such as surgery. If the transmission distance of the High Definition Multimedia Interface (HDMI) cable is only about 5 meters under a platform with strong computing power, this limitation may cause certain limitations on the image transmission of high-definition devices. At present, the failure rate of all-in-one multimedia platforms is high and replacement is complicated. The modular OPS pluggable standard greatly simplifies the cost of rapid switching and maintenance. Summary of the invention

DETAILED DESCRIPTION

[0022] The present invention is further described in detail below in conjunction with test examples and specific implementation methods. However, this should not be understood as the scope of the above subject matter of the present invention being limited to the following embodiments, and all technologies realized based on the content of the present invention belong to the scope of the present invention.

[0023] Example 1 like Figure 1 As shown, a modular multimedia OPS (Open Pluggable Specification Plus) player box includes an OPS module, a first module and a second module; The OPS module includes a CPU module; Acquire a first signal, the CPU module converts the first signal into an HDBaseT signal, and sends the HDBaseT signal to the first module, and the first module converts the HDBaseT signal into an HDMI signal; Acquire a second signal, and send it from the CPU module to the first module, and send the HDMI signal and the second signal from the first module to the second module together; The second module includes a video module and a screen component, the video module receives the HDMI signal, converts the HDMI signal into an LVDS signal for driving the screen component; The screen assembly is connected to a plurality of multimedia integrated displays so that the plurality of displays can display different contents simultaneously.

[0024] The OPS module also includes a transmitting chip, and the first signal is converted into an HDBaseT signal by the transmitting chip.

[0025] The sending chip uses a VS2310TX chip to send signals, and the multimedia integrated display uses a VS2310RX chip to receive signals.

[0026] The HDBaseT signal is sent from the CPU module to N interfaces of the OPS device, and the N interfaces output the HDBaseT signal to the first module, where N is a positive integer less than or equal to 4.

[0027] The interface is an RJ45 interface; the first signal includes USB, HDMI and serial port signals, and the second signal is an OPS module video signal.

[0028] The video module simultaneously receives an external HDMI signal and an external infrared control signal to switch the LVDS signal.

[0029] The OPS adapter board is also provided with any one or more of the following interfaces: an input USB interface and an output USB interface for connecting the OPS adapter board to receive OPS signals, an HDMI interface for connecting a video module to control signals, a multi-channel serial interface and a USB interface for connecting an OPS module and a CPU module, and a USB interface for connecting an external operating device for manipulation.

[0030] The screen assembly and a plurality of multimedia integrated displays transmit signals via HDMI.

[0031] The multimedia integrated display can be selected as a master device or a slave device through the function of the OPS module; The OPS module is used as the main device, with the CPU module as the main platform, and achieves less than or equal to four HDBaseT signal outputs by adding HDBaseT function; The OPS module acts as a slave device, takes the sending chip as a platform, and realizes display by using several multimedia integrated displays and one OPS module through extended display function.

[0032] As a specific embodiment, Figure 2As shown, the high-performance OPS computer device is used as the master device, and the media integrated display is used as the slave device. The master device and the slave device are connected through the OPS standard interface. The high-performance OPS computer device uses Intel CPU as the main platform, adopts the OPS protocol specification design standard, and adds HDBASE-T function, which can support up to four HDBASE-T outputs.

[0033] The master device can also be used as a slave device as a multimedia integrated display by replacing the OPS module. If a high-performance OPS computer device is used as a slave device and the HDBASE-T conversion chip is used as a platform, the display, USB, serial port, audio and other functions can be simply expanded. It does not have complete OPS functions, but five sets of multimedia displays can save four sets of OPS modules, effectively reducing costs.

[0034] like Figure 3 As shown, the high-performance OPS computer device includes an OPS module. In the OPS module, the CPU sends USB, HDMI and serial port signals to the HDBT transmitter chip (VS2310TX), which then converts them into HDBASE-T signals and connects them to the RJ45 interface of the OPS device. The multimedia integrated display is a simple receiving chip (VS2310RX). After the signal is transmitted from the high-performance OPS computer device to the receiving chip through the network cable, the chip restores the signal to USB, HDMI and serial port signals and sends them to the screen and other peripherals.

[0035] Specifically, Figure 4 For example, a high-performance OPS computer device includes a video & power board, a screen assembly, an OPS adapter board, and an OPS module; Combination Figure 5 Further explanation: the video and control signals of the CPU are input to the sending chip VS2310TX through HDMI, RS232, USB, etc. for multimedia signal processing. Each signal is converted into an HDBT signal and transmitted to the RJ45 interface, supporting up to four interface outputs; another signal is output as an OPS module video signal through HDMI; See also Figure 6 , the output HDBT signal is transmitted to the OPS adapter board, which converts it into an HDMI signal. The video & power board can receive infrared control signals to achieve remote control of the playback box, and can also receive signals input through the HDMI interface, such as video and audio signals from computers, game consoles, etc.; all HDMI signals are converted into LDVS signals after video processing and sent to the screen component for display on the screen; The OPS adapter board receives audio data input from an external audio device and a USB device at the same time, and the data can be independently displayed and controlled, and can also be backed up.

[0036] The output video signal is received by the multimedia integrated display, and the multimedia integrated display is connected to the OPS computer device through the OPS accessory board, in which the OPS standard interface is responsible for transmitting the HDMI signal.

[0037] OPS can be embedded in display devices to achieve plug-in connection between the display and the player. No additional power and data cables are required. HDBaseT technology is applied to the OPS technical specifications. OPS itself can be used as a player, and then converted into HDBaseT signal through HDBaseT chip technology, thereby simplifying the need for long-distance transmission wiring. Through HDBaseT, system functions can be easily expanded. HDBaseT2.0 uses the 2.0 protocol and supports the transmission of 4K, USB, RS232 and audio. The distance can reach 100M. The Intel CPU used in this patent also supports the output of high-definition display.

[0038] Currently, processors support multiple monitors with different display modes, which can make multiple monitors display relatively independent content independently, greatly simplifying multimedia applications. Modern processors usually support multiple monitors with different display modes, which means that multiple monitors can be connected to the same computer, and each monitor can display independent content. This function greatly simplifies multimedia applications and multitasking.

[0039] Through multiple monitors with different displays, users can display different content on different screens at the same time, improving work efficiency and user experience.

[0040] For example, in video editing, you can display the video material on one screen while doing editing work on another screen; in games, you can display the game interface on one screen and the game chat window or other auxiliary functions on another screen.

[0041] This feature is particularly useful for professional users and multimedia creators, as it provides a larger workspace and more flexible operation methods. At the same time, multiple monitors also bring better multitasking capabilities to ordinary users, making it more convenient and efficient to handle multiple applications at the same time.

[0042] HDBaseT technology is an extension of display technology, which can transmit lossless image quality over longer distances. Compared with HDMI, HDBaseT has a great advantage in that it can achieve longer distance transmission and maintain lossless image quality during the transmission process. This means that HDBaseT technology can transmit high-definition video, audio and other signals to farther locations without affecting the signal quality.

[0043] HDBaseT technology also supports the transmission of multiple signals, including HD video, audio, Ethernet, power and control signals, through a single network cable (such as Cat5e, Cat6 or Cat6a). This integrated transmission feature makes installation and wiring more simplified and cost-effective.

[0044] Therefore, the use of HDBaseT technology can provide greater flexibility and convenience, and is particularly suitable for application scenarios that require long-distance transmission of high-quality multimedia signals, such as conference rooms, digital billboards, home theaters, etc. It brings users a better viewing experience and convenience of system integration.

[0045] The present invention adopts Intel 11th Core series CPU, which has two DDI (Digital Display Interface) interfaces and 4 groups of TCP (Type-C Port), the TCP interface supports HDMI 2.0, and the platform supports four-way different displays.

[0046] This embodiment provides a flexible and scalable hardware architecture, especially for application scenarios that require high-performance computing and multimedia processing capabilities. With OPS multi-channel display signals, and by integrating CPU redundant resources (USB, serial ports, etc.) into HDBaseT technology, system functions can be easily expanded, such as cameras, audio equipment, etc., without the need for additional wiring.

[0047] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
