摘要
在飞机飞行过程中记录的座舱内外视景、座舱各仪表的画面以及座舱语音内容等信息,对于平时飞行训练评估、战时调查分析以及新型飞机的研制和试飞具有十分重要的现实意义。叙述了一种机载多路数字音视频记录系统的软硬件设计与实现,该记录系统的数据流格式为MPEG-4,最多可记录8路视频和2路音频长达20小时左右。
The flying audio and video （AV） information inside or outside the cabin can be recorded in real time. The recorded information is very important in evaluating flight quality and researching in wartime, which is available for the development of a new type of avion at the same time, This is an airborne multi-channel digital AV recorder system. The hardware and software of this system arc introduced in details. The recorder format of this system is measured up with MPEG-4 standards. It can attain twenty hours to record eight channels video and two channels audio signal.
