[0029] In some embodiments, the input device is accessed via a target interface, the target interface including a preset identification pin for identifying device information, and the target identification result further including target video parameters supported by the input device. The step of identifying the device information of the input device in response to the input device access operation to obtain the target identification result corresponding to the input device includes: In response to the access operation of the input device, the level state of the preset identification pin is detected to obtain the pin level detection result; The target device type of the input device is determined based on the pin level detection results; The target communication protocol is determined based on the target device type; the target communication protocol characterizes the rules for communicating device information with the input device; A communication connection is established with the input device based on the target communication protocol to obtain the target video transmission protocol and the target video parameters.

[0030] In some embodiments, the target interface of the video interface processing system includes a preset identification pin for identifying device information. The access operation of the input device will affect the level state of the preset identification pin. Therefore, by detecting the level state of the preset identification pin, the target device type of the input device can be determined, such as whether the input device is a DP device or a USB device.

If the target video parameters are consistent with the actual video parameters, it indicates that the target video parameters supported by the input device obtained through the communication protocol handshake are accurate. Then, the target video parameters are transmitted to the target display device, and the target display device generates subsequent AR images based on the target decoding signal and the target video parameters.

[0034] This application embodiment further confirms the actual video parameters supported by the input device by sampling and analyzing the input signal transmitted by the input device in real time, preventing inaccurate device information reported by the input device and improving the reliability of the video interface processing system.

The step of configuring a preset reconfigurable logic circuit based on the target decoding configuration information to reconstruct a target signal decoding circuit corresponding to the target video transmission protocol includes: The decoding algorithm configuration information, the image preprocessing configuration information, and the signal output format configuration information are loaded into the preset reconfigurable logic circuit to reconstruct the target signal decoding circuit. The target signal decoding circuit is used to decode the input signal to obtain a first video signal, perform image preprocessing on the first video signal to obtain a second video signal, and perform format conversion processing on the second video signal to obtain the target decoded signal.

[0036] In some embodiments, the target decoding configuration information includes decoding algorithm configuration information, image preprocessing configuration information, and signal output format configuration information corresponding to the target video transmission protocol. This configuration information is loaded into a preset reconfigurable logic circuit to reconstruct the target signal decoding circuit corresponding to the target video transmission protocol. The target signal decoding circuit decodes the input signal transmitted from the input device to obtain a first video signal, performs image preprocessing on the first video signal to obtain a second video signal, and performs format conversion processing on the second video signal to obtain the target decoded signal corresponding to the input signal. Image preprocessing includes color space conversion (e.g., from RGB to YUV), contrast enhancement, and color gamut mapping to make the video signal more suitable for the optical display characteristics of AR-HUD. Format conversion processing refers to converting the video signal into a unified, optimized format, such as LVDS. Finally, the controller transmits the target decoded signal to the target display device via a unified internal high-speed bus (e.g., LVDS).

[0037] This application embodiment identifies the video transmission protocols of different devices and dynamically reconstructs the corresponding decoding circuits. The system can be compatible with multiple different video transmission protocols, improving the versatility and compatibility of the video interface processing system. By loading different decoding configuration information to change the system function, it can adapt to multiple existing and future video transmission protocols, improving the flexibility and scalability of the video interface processing system. It eliminates the need to set fixed decoding circuits for different video transmission protocols, realizing the reuse of hardware resources. By using the reconstructed decoding circuit to perform image preprocessing and standardized format conversion on the video signal, it improves the display performance of the target display device.

[0038] In some embodiments, after configuring the preset reconfigurable logic circuit based on the target decoding configuration information to reconstruct the target signal decoding circuit corresponding to the target video transmission protocol, the method further includes: The preset signal receiver is configured to operate in a target mode corresponding to the target video transmission protocol. The preset signal receiver in the target operating mode is used to receive the input signal and transmit the input signal to the target signal decoding circuit.

In addition to configuring the preset reconfigurable logic circuit, the preset signal receiver also needs to be configured to operate in a target mode corresponding to the target video transmission protocol. In the target operating mode, the preset signal receiver can receive input signals transmitted from the input device and transmit them to the target signal decoding circuit.

[0041] In some embodiments, the method further includes: In response to the disconnection operation of the input device, the target signal decoding circuit is reset.

[0042] In some embodiments, after the input device is disconnected, the target signal decoding circuit and the preset signal receiver in the target operating mode need to be reset to their initialization state. The disconnection operation of the external device can be an external device unplugging operation, and the disconnection operation of the vehicle's embedded system can be a HUD function deactivation operation.
