摘要
针对机载多路音视频记录系统的高分辨率、大数据量和高实时性要求,提出一种基于嵌入式平台的实时多路音视频采集、编码和存储系统.该系统采用达芬奇硬件平台实现音视频采集控制及编码,同时采用FPGA完成数据缓存和传输控制,从而实现四路XGA(1024×768@60帧/s)视频、一路PAL(720×576@25帧/s)视频和两路音频的高效实时存储.测试结果表明,该系统稳定可靠,可实现多路音视频的采集、存储功能,图像清晰度高,实时性好,在机载音视频记录领域里可以得到广泛的应用.
Abstract
Aiming at the requirements of high resolution,mass of data and high real-time performance for airborne multi-channel audio/video recording systems,a real-time multi-channel audio/video recording system was proposed based on embedded platform.Davinci video processors from Texas Instruments Incorporated (TI) were adopted to control the efficient real-time digitizing,coding and storage for four-channel XGA (1024×768@60 frames/s) videos,one channel PAL (720×576@25 frames/s) video,and two-channel audios.Cyclone devices were exploited to transmit the compressed multimedia data.The testing results show that the system can implement recording and storage of multi-channel audio and video signal with high image resolution and good real-time performance.The system can find wide applications in the field of airborne recorders.
