A low delay transmission method of multi-channel video based on FPGA

摘要：

　　In order to guarantee the fluency of multi-channel video transmission in video monitoring scenarios,we designed a kind of video format conversion method based on FPGA and its DMA scheduling for video data,reduces the overall video transmission delay.In order to sace the time in the conversion process,the parallel ability of FPGA is used to video format conversion.In order to improve the direct memory access(DMA)writing transmission rate of PCIe bus,a DMA scheduling method based on asynchronous command buffer is proposed.The experimental results show that this paper designs a low delay transmission method based on FPGA,which increases the DMA writing transmission rate by 34%compared with the existing method,and then the video overall delay is reduced to 23.6ms
