摘要
为了克服多处理器系统传输效率低的问题,满足高分辨率视频的实时编码传输需求.采用单片FPGA+ARM架构处理器,提出一种视频传输系统设计方法,在FPGA中实现视频的采集和编码,在ARM中实现码流的网络封装及传输.该设计方法充分利用了FPGA高速处理大量数据的优势和ARM丰富的设计资源,能以较小的体积实现较高效的视频传输系统,相较于使用多处理器搭建的系统,具有更高的集成度和灵活性.测试结果表明系统运行流畅,基本可以实现视频的实时编码传输.
In order to overcome the problem of low transmission efficiency of multi-processor systems and meet the requirements of high-resolution video real-time encoding and transmission.Proposes a design method of video transmission system based on single-chip FPGA+ARM processor.Using FPGA to complete video capture and encoding;using ARM to implement bitstream encapsulation and transmission.The method take full advantage of FPGA processing mass data and the design resources of ARM,achieve a high efficiency video transmission system in a small volume,compared with the systems built by multi-processor,this system has higher integration and flexibility.Test results show that the system runs smoothly and can basically achieve real-time video encoding and transmission.
