| The aviation video data reflects the flight status of plane, it mainly contains two aspects data: one is head-up-display frame and the other is the outside scene ahead the plane. The cassette machine was used as traditional record method. The data recorded in the cassette machine was original data and the amount is so large. Because the vibration environment in plane, it should have an excellent mechanical parts and the cassette machine has a huge volume and weight, a larger cabin space was took up.With the development of aviation electronics technology and video processing technology, the cassette-recording system was replaced by digital aviation video recording system. This system not only realizes digital video, but also has a number of advantages such as small size, easy storage, high reliability and low cost, it is the ideal solution of aviation video recording system.A MPEG-4 embedded aviation video compression recording system based on IME6400 was designed and realized, this system realizes compression and storage of aviation video data, and can satisfy the requirements of the video-recording system. First, research background and significance are expounded. Compression standard and overall design scheme are proposed under the technical development contrast at home and abroad.Next, expounds the realization method of the hardware overall design whose core are S3C2440A and IME6400 and sub-modules.Third, introduces the configuration procedure of IME6400 and constructs the software platform based on embedded Linux OS. At the same time, expounds the transplant procedure of Linux and software realization based on it.Finally, describes the test method and procedure of the system according to actual conditions and the results show that this system can satisfy the requirements of aviation video recording system. |
