ARINC 818名为Avionics Digital Video Bus(ADVB)，是驾驶舱视频的标准，已在商业和军用驾驶舱中获得广泛接受，包括波音787、A350XWB、A400M、KC-46A和许多其他机型。ARINC 818最初设想用于驾驶舱显示器，由于其高带宽和高可靠性，现在正在传播到高速传感器中，如红外和光学相机。ARINC 818规范最初发布于2006年，最近经历了重大更新，将增强其作为高速传感器接口的适用性。ARINC 818-2规范于2013年12月发布。对该规范的修订包括：视频切换、立体声和3-D规定、色彩顺序实现、感兴趣区域、仅数据传输、多通道实现、双向通信、更高的链路速率至32Gbps、同步信号、高速同轴电缆接口选项和光接口细节。对于存在吞吐量瓶颈和交换问题的高带宽多传感器系统，该规范的附加内容尤其具有吸引力。ARINC 818在铜缆或光纤高速物理层上实施，允许将多个传感器时分复用到一条链路上。本文讨论了ARINC 818-2规范中的每一项新功能及其对ISR和对策实施的好处，并提供了几个例子。
ARINC 818, titled Avionics Digital Video Bus (ADVB), is the standard for cockpit video that has gained wide acceptance in both the commercial and military cockpits including the Boeing 787, the A350XWB, the A400M, the KC- 46A and many others. Initially conceived of for cockpit displays, ARINC 818 is now propagating into high-speed sensors, such as infrared and optical cameras due to its high-bandwidth and high reliability. The ARINC 818 specification that was initially release in the 2006 and has recently undergone a major update that will enhance its applicability as a high speed sensor interface. The ARINC 818-2 specification was published in December 2013. The revisions to the specification include: video switching, stereo and 3-D provisions, color sequential implementations, regions of interest, data-only transmissions, multi-channel implementations, bi-directional communication, higher link rates to 32Gbps, synchronization signals, options for high-speed coax interfaces and optical interface details. The additions to the specification are especially appealing for high-bandwidth, multi sensor systems that have issues with throughput bottlenecks and SWaP concerns. ARINC 818 is implemented on either copper or fiber optic high speed physical layers, and allows for time multiplexing multiple sensors onto a single link. This paper discusses each of the new capabilities in the ARINC 818-2 specification and the benefits for ISR and countermeasures implementations, several examples are provided.
