基于FC-AV协议的视频传输系统
摘要
在现代航空航天电子领域,各种机载设备之间视频数据传输量与日俱增,对总线的带宽也越来越高。美国国家标准协会提出了一种基于光纤通道的视频传输协议(ANSI INCITS 356-2002),充分利用光纤通道协议高带宽、低延迟、对距离不敏感和抗电磁干扰能力强等特点,提供数字音频、视频到FC帧的映射规则,广泛适用于航天系统中传感器和显示器网络的音视频传输。
在本文中,首先对FC-AV协议进行了简单的阐述,着重对容器系统、帧头控制协议(FHCP)进行了较为详细的介绍,包括帧头的格式、映射方式等,这是整个论文的理论基础。接着介绍了具体的系统实现方案,并在深入研究现有协议的基础上,提出了一种基于现有方案的“四屏显示”技术,充分体现了FC-AV协议的特点和优势。
本文的主要内容有:
1:研究了光纤通道协议以及它在航空电子环境下的协议子集FC-AV的内容,并在协议基础上提出了一种可实现大容量视频传输的方案。
2:详细研究了IIC总线技术和图像缩放技术,完成了FPGA内部各个功能模块的设计和仿真,利用Xilinx ISE 10.2软件完成了综合仿真和布局布线。
3:利用ML506开发板,实现了基于FC-AV协议的视频传输系统。
With the increase of video data transported between all kinds of devices in the avionics field nowdays, high bandwidth bus technology is required more and more. American National Standards Institute proposed a Fibre Channel-based video transport protocol (ANSI INCITS 356-2002), which makes full use of the advantages of Fibre Channel, such as: high-bandwidth, low latency, insensitive over distance and strong anti-electromagnetic interference. The protocols provide mapping rules from digital data to FC frames and are being widely used in sensor networks and display networks.
Firstly,in this article FC-AV protocol is simply described and some important concepts are focused on ,which are container system and frame header control protocol (FHCP), including the header format, mapping methods, which are the theoretical basis of this entire paper. Secondly,in this paper a specific system implementation is described and a“Four-Screen Display”program based on deep study of existing protocols is proposed. This optimized program fully reflects the FC-AV protocol’s characteristics and advantages.
The main contents of this paper as follows:
1. Study the FC protocol and its subset– FC-AV protocol and propose a large-capacity video transmission program.
2. Study the IIC bus technology and image scaling technology; all the modules were designed, simulated and layouted in the FPGA with the help of Xilinx ISE10.2.
3. Us ML506 development board to implement the video transmission system based on FC-AV protocol.
