[0050] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0051] Reference Figure 1 , Figure 1This is a schematic diagram of the computer device structure of the hardware operating environment involved in the embodiments of the present invention.

[0052] like Figure 1 As shown, the computer device may include: a processor 1001, such as a central processing unit (CPU), a communication bus 1002, a user interface 1003, a network interface 1004, and a memory 1005. The communication bus 1002 is used to enable communication between these components. The user interface 1003 may include a display screen or an input unit such as a keyboard; optionally, the user interface 1003 may also include a standard wired interface or a wireless interface. The network interface 1004 may optionally include a standard wired interface or a wireless interface (such as a Wireless-Fidelity (Wi-Fi) interface). The memory 1005 may be high-speed random access memory (RAM) or stable non-volatile memory (NVM), such as a disk drive. The memory 1005 may also optionally be a storage device independent of the aforementioned processor 1001.

[0053] Those skilled in the art will understand that Figure 1 The structure shown does not constitute a limitation on the computer device and may include more or fewer components than shown, or combine certain components, or have different component arrangements.

[0054] like Figure 1 As shown, the memory 1005, which serves as a storage medium, may include an operating system, a network communication module, a user interface module, and a display signal transmission program.

[0055] exist Figure 1 In the computer device shown, the network interface 1004 is mainly used for data communication with the network server; the user interface 1003 is mainly used for data interaction with the user; the processor 1001 and the memory 1005 in the computer device of the present invention can be set in the computer device, and the computer device calls the display signal transmission program stored in the memory 1005 through the processor 1001 and executes the display signal transmission method provided in the embodiment of the present invention.

[0056] This invention provides a method for transmitting display signals, referring to... Figure 2 , Figure 2 This is a flowchart illustrating the first embodiment of the signal transmission method of the present invention.

[0057] In this embodiment, the display signal transmission method includes the following steps:

[0058] Step S10: Obtain the high-speed serial signal from the target port and deserialize the high-speed serial signal to decode the data with the preset encoding specification into the original data.

[0059] It should be noted that serial communication, as one of the computer communication methods, mainly serves to transmit data between the host and peripherals, as well as between the host and peripherals. Serial communication has the characteristics of fewer transmission lines and lower cost, and is mainly suitable for short-distance human-machine interaction, real-time monitoring and other system communication work. It can also achieve long-distance transmission with the help of the existing telephone network. Therefore, the serial communication interface is a commonly used interface in computer systems.

[0060] It is understandable that the specific methods of the existing solutions are as follows: Figure 3 As shown, the typical DisplayPort receiving and application scheme involves the graphics card on the host or laptop outputting a DisplayPort signal, which is then received and processed by a decoding chip on the monitor or other display device.

[0061] It's important to note that DisplayPort (DP) is a digital video interface standard developed by a consortium of PC and chip manufacturers and standardized by the Video Electronics Standards Association (VESA). This interface requires no certification or licensing fees and is primarily used for connecting video sources to devices such as monitors. It also supports audio, USB, and other forms of data transmission. This interface was designed to replace traditional VGA, DVI, and FPD-Link (LVDS) interfaces. Through active or passive adapters, it is backward compatible with traditional interfaces such as HDMI and DVI.

[0062] It is understood that the execution subject in this embodiment is defined as the test box FPGA Display port RX, therefore the solution in this embodiment is as follows: Figure 4 As shown, relative to Figure 3The proposed solution allows the system to receive DisplayPort signals from a host computer, laptop, or camera sensor via the FPGA of the test box. The test box then receives and decodes the DisplayPort signals. The received image data is transmitted via a QSFP optical module and then through fiber optic cable to the 10 Gigabit Ethernet acquisition card on the host computer (PC) for final processing. This system is compatible with receiving DisplayPort signals from common host computers or laptops, and can also receive DisplayPort signals from newly added camera sensors in the image testing field. After receiving and decoding, the image data can be transmitted to the host computer (PC) for relevant testing applications. The host computer can flexibly process the transmitted DisplayPort image data as needed, not just for display. Compared to ordinary DisplayPort reception methods, this system offers flexible configuration in terms of supported rate levels, with a maximum reception rate of up to 12Gbps / Lane. This not only meets the testing needs of newly added camera sensors with DisplayPort output, but also provides greater flexibility and higher efficiency in image data processing applications and supported rates.

[0063] Understandably, a sensor generally refers to a Decromon temperature sensor. A Decromon temperature sensor is a detection device that can sense the measured information and transform that information into an electrical signal or other required form of information according to a certain rule, to meet the requirements of information transmission, processing, storage, display, recording, and control. It is the primary link in realizing automatic detection and automatic control.

[0064] In specific implementation, such as Figure 5 As shown, the entire processing flow is as follows: the DisplayPort signal output from the host, laptop, or camera sensor is sent to the test box FPGA. The test box FPGA receives and decodes the high-speed serial data of the DisplayPort using SerDes. Then, as needed, it descrambles and reassembles the received Lane data. The decoded image data is packaged and buffered by the Buffer module, and then transmitted to the 10 Gigabit Ethernet acquisition card on the host (PC) through the 10 Gigabit Ethernet fiber optic network. Finally, the 10 Gigabit Ethernet card transmits the data to the host for application processing through the PCIe bus interface.

[0065] It is understandable that, taking the FPGA test box as the execution subject in this embodiment as an example, the entire method's processing flow is as follows: Figure 6 The process is shown below.

[0066] Furthermore, in order to improve the processing effect of serial signals, the step of acquiring a high-speed serial signal from the target port and deserializing the high-speed serial signal to decode the data with a preset encoding specification into the original data includes: acquiring a high-speed serial signal from the target port, acquiring data with 8B / 10B encoding from the high-speed serial signal; and decoding the data with 8B / 10B encoding into unencoded original data according to the 8B / 10B encoding specification.

[0067] It should be noted that encoding is the process of converting information from one form or format to another; it is also known as the code in computer programming languages, or simply encoding. It involves using pre-defined methods to encode text, numbers, or other objects into digital codes, or to convert information or data into specified electrical pulse signals. Encoding is widely used in electronic computers, television, remote control, and communications. Decoding is the reverse process of encoding.

[0068] In practice, the SerDes module of the test box FPGA receives and deserializes the input DisplayPort high-speed serial signal, and decodes the input data with 8B / 10B encoding into unencoded raw data according to the 8B / 10B encoding standard.

[0069] In a specific implementation, before the step of obtaining a high-speed serial signal from the target port and obtaining data with 8B / 10B encoding from the high-speed serial signal, the method further includes: obtaining transmission requirements and matching the receiving rate of the target port according to the transmission requirements. The receiving rates include: 1.62Gbps, 2.7Gbps, 4.4Gbps, 5.4Gbps, 6.0Gbps, 6.6Gbps, 8.1Gbps, 8.7Gbps, 9.0Gbps, 9.6Gbps, and 12Gbps.

[0070] Step S20: Descramble the original data according to the preset descrambling algorithm.

[0071] Furthermore, in order to improve the overall running speed without interference data, the step of descrambling the original data according to the preset descrambling algorithm includes: determining whether the original data is scrambled; if so, obtaining the descrambling algorithm corresponding to the target port and descrambling the original data according to the descrambling algorithm; if not, executing the step of repackaging the descrambled current original data according to preset rules to generate image data packets through a preset bypass strategy.

[0072] In practice, the original Lane data of the DisplayPort after 8B / 10B decoding is descrambled according to the descrambling algorithm defined in the DisplayPort specification. If the original Lane data of the DisplayPort is not scrambled, the descrambling process can be bypassed by setting it up, and the original data can be directly output to the backend application.

[0073] Step S30: Pack the descrambled current raw data into image data packets according to preset rules.

[0074] Furthermore, in order to enable the data packets to run more smoothly within the execution entity of this embodiment, the step of assembling the descrambled current original data into image data packets according to preset rules includes: obtaining the data transmission encoding rules corresponding to the target port and the preset image data packet length; and assembling the original data into image data packets according to the data transmission encoding rules and the preset image data packet length.

[0075] It should be noted that this module is used to group the received and descrambled Lane data into image data packets according to the Lane data transmission encoding rules and the set image data packet length in the DisplayPort specification. This module can support data packetization in 1-Lane, 2-Lane, 3-Lane, and 4-Lane scenarios.

[0076] Step S40: Obtain internal preset transmission rules and encapsulate image data packets according to the internal preset transmission rules to generate target data.

[0077] In practice, to facilitate buffered transmission within the test box, the packaged image data needs to be repackaged according to the internally defined data transmission rules so that the Buffer module can buffer and transmit the image data.

[0078] Step S50: Encapsulate the target data according to the MAC protocol to generate a MAC protocol encapsulation package.

[0079] Understandably, the image data cache control unit also includes read and write control of the DDR memory unit on the test box, writing the packaged data packets into the DDR for caching, and reading the data packets cached in the DDR and sending them to the backend MAC module so that they can be transmitted to the host via the 10 Gigabit fiber optic network.

[0080] Furthermore, in order to achieve the effect of accessing the image through the storage device, before the step of encapsulating the target data according to the MAC protocol to generate a MAC protocol encapsulation packet, the method further includes: sending the image data packet to the target storage device for storage; and when a call instruction is received, sending a signal to the target storage device to obtain the image data packet from the target storage device.

[0081] It should be noted that the image data cache control unit also includes read and write control of the DDR memory unit on the test box. It writes the packaged data packets into the DDR for caching, and can also read the data packets cached in the DDR and send them to the backend MAC module so that they can be transmitted to the host via the 10 Gigabit fiber optic network.

[0082] Understandably, the system receives and selects MAC packets from the 10G Ethernet optical module, processes them, and sends them to the control command module for the MCU to execute, thereby enabling communication control between the test box and the host. At the same time, the image data buffered in the buffer is packaged according to the MAC protocol and sent to the dedicated image acquisition card for reception via the 10G Ethernet optical module.

[0083] In a specific implementation, the step of obtaining internal preset transmission rules and encapsulating the image data packets according to the internal preset transmission rules to generate target data includes: obtaining internal preset transmission rules, which are a type I rule and a type II rule; when it is detected that the image data packets will be cached, encapsulating the image data packets according to the type I rule; when it is detected that the image data packets do not need to be cached, encapsulating the image data packets according to the type II rule.

[0084] It should be noted that the first and second types of rules in this embodiment are only used to distinguish between the two types of rules, and there is no prescribed order. The first type of rule is to further encapsulate and package the packetized image data according to the internally defined data transmission rules in order to facilitate the buffer module to cache and transmit the image data. The second type of rule is to encapsulate the image data when the image data does not need to be cached and can proceed directly to the next step of the process.

[0085] Step S60: Send the MAC protocol encapsulation packet to the target image acquisition card to realize signal transmission to the target host.

[0086] It should be noted that in this embodiment, special processing is performed for the low-power mode reception of the camera module's DisplayPort signal. The SerDes is controlled to switch between different stages of low power and normal transmission, so that the SerDes can maintain stable reception of the low-power mode DisplayPort signal.

[0087] Understandably, the control unit is responsible for controlling the operation of the entire image test box FPGA, receiving control commands sent by the application end through fiber optic transmission, and providing the host application end with the relevant working status of the test box.

[0088] In practical implementation, the test box control command transceiver module forwards the control commands parsed from the MAC to the MCU, and at the same time feeds back the internal working status information of the test box collected by the MCU to the host application, thereby realizing communication control between the test box and the host.

[0089] It should be noted that the 10G Ethernet module controls the conversion of MAC packet data into high-speed serial data for transmission through the optical module. At the same time, it deserializes the high-speed serial data received by the QSFP optical module to form MAC packets, which are then sent to the MAC module for parsing.

[0090] Understandably, the test box is connected to the host's 10 Gigabit Ethernet acquisition card via a QSFP optical module using optical fiber, enabling data transmission and command communication control with the host. The test box can transmit data with the host at a maximum bandwidth of 40 Gbps via the QSFP optical module.

[0091] In specific implementations, this embodiment can achieve the same effect in other ways. For example, the FPGA can use different dedicated chips or chips such as microcontrollers and DSPs to implement the functions of each sub-module; or QSFP fiber optic 10 Gigabit Ethernet transmission can be replaced with USB, Gigabit Ethernet, Thunderbolt transmission, PCIe direct input, etc. to achieve the same data transmission and communication control effect; in terms of interfaces, the fiber optic port can also be replaced with USB port, network port, Thunderbolt port, PCIe interface, etc., which are available on the host (PC).

[0092] This embodiment receives high-speed serial data from a preset port, decodes the data, descrambles and reassembles the decoded data, encapsulates the data using the MAC protocol, and transmits it to the host. This enables the reception of DisplayPort signals from a host, laptop, or camera sensor. After receiving and decoding the image data, it can be transmitted to the host for relevant testing applications. The host can flexibly process the transmitted DisplayPort image data as needed; it is also more flexible and efficient in terms of image processing applications and supported speeds.

[0093] Furthermore, embodiments of the present invention also propose a computer-readable storage medium storing a program for display signal transmission, wherein when the program for display signal transmission is executed by a processor, it implements the steps of the display signal transmission method as described above.
