The flying Audio and Video ( AV) information recorded in real time is very important in evaluating flight quality and researc-hing in wartime,which is available for the development of a new type of avion at the same time. Currently on the market multi-channel digital AV recorder uses DSP or CODEC circuit and peripheral circuit to implement,system complexity is higher,and the flexibility is poor. In view of the shortage of the existing implementation way and the system requirements,propose a system architecture of multi-channel digital AV recorder based on SoPC. Then expound the composition of the AV recorder system,the peripheral interface circuit,the design and implementation of SoPC logic and SoPC software. The test shows that the function and performance of multi-channel digital AV recorder completely meets the system requirements.
