Embodiment Construction
[0035] Such as Figure 1-Figure 4 A kind of video stream conversion method shown, comprises the steps:
[0036] Step 1: Establish a video acquisition unit, a video processing unit, and an external cache unit, and both the video acquisition unit and the external cache unit are connected to the video processing unit;
[0037] The video acquisition unit is a camera or an infrared camera, and the video processing unit is an FPGA processor;
[0038] Step 2: Establish a Cameralink receiving and processing module, an internal cache module, a video arbitration processing module and a standard format video stream sending driver module in the video processing unit;
[0039] The Cameralink receiving and processing module converts the serial data of the high-speed video stream from the infrared camera by calling the Serdes primitive of xilinx FPGA, and analyzes the video frequency, field synchronization and data signals according to the Cameralink standard.
[0040] Step 3: the Camerali...
