| Abstract: | An embedded small size airborne video recording system based on DOM storage is designed and realized.The system is composed of the embedded control module SOM2386 and the video processing chip AISC-SZ1510.The main concept is presented,and the hardware design of the video and audio decoder and encoder,interface,control and storage units are described.Finally the whole working flow of the system software is also described.The system's physical volume is very small,the weight is light,the anti-vibration property is nice,and the operation and maintenance are convenient.It has been applied in an aircraft. |
