摘要
为了提高短距离无线视频传输的高速性、实时性和稳定性,基于FPGA设计了一种采用无线光通信技术的高清视频传输系统。该系统由高清摄像头、数据缓存器,调制电路、激光器、光学天线、光电探测器、解调电路和显示单元组成,采用UDP数据传输协议。系统实现了500万像素级别高清实时视频信号的传输。在应急通信、救灾、民用多媒体系统以及远程医学等领域具有广泛的应用潜力。
In order to improve the transmitting speed,real-time and stability of short distance wireless video transmission,a FPGA based high-defi nition video transmission system using free space optical communication technology is proposed.The system employing UDP data transmission protocol and it is composed of high-defi nition camera,data cache,modulation circuit,laser,optical antennas,photodetector,demodulation circuit and display unit.The system realizes the transmission of high-definition real-time video signal at the level of 5 million pixels.It has a wide application potential in the fi elds of emergency communication,disaster relief,civil multimedia system and remote medicine.
