Hardware Design of Video Compression System in the UAV Based on the ARM Technology

The video compression system is a key component of video data transfer system in the unmanned aerial vehicles (UAV). To satisfy the requirement of the wireless video transfer this paper puts forward a cost effective, power efficient and low profile video compression schemes based on the H.264 technology. The video compression system consisted of a video decoder module based on TVP5150, an H.264 CODEC based on the i.MX27, an video encoder module based on CH7024, memory, external control module and power supply unit. Later the video compression software was introduced also. The video compression system can not perform well in the flying experiment, and the flying experiment proved the correction and robustness of the system.
