The ARINC 818 Avionics Digital Video Bus is the standard for cockpit video that has gained wide acceptance in both the commercial and military cockpits. The Boeing 787, A350XWB, A400M, KC-46A, and many other aircraft use it. The ARINC 818 specification, which was initially release in 2006, has recently undergone a major update to address new avionics architectures and capabilities. Over the seven years since its release, projects have gone beyond the specification due to the complexity of new architectures and desired capabilities, such as video switching, bi-directional communication, data-only paths, and camera and sensor control provisions. The ARINC 818 specification was revised in 2013, and ARINC 818-2 was approved in November 2013. The revisions to the ARINC 818-2 specification enable switching, stereo and 3-D provisions, color sequential implementations, regions of interest, bi-directional communication, higher link rates, data-only transmission, and synchronization signals. This paper discusses each of the new capabilities and the impact on avionics and display architectures, especially when integrating large area displays, stereoscopic displays, multiple displays, and systems that include a large number of sensors.

Many commercial and military aircraft still use analog video, such as RS-170, RS-343, or STANEG 3350. Though the individual digital components many be inexpensive, the cost to certify and retrofit an entire aircraft fleet may be prohibitively expensive. A partial or incremental upgrade program where analog cameras remain in use but data is converted and processed digitally can be an attractive option. This paper describes Great River Technology's experience in converting multiple channels of RS-170 and multiplexing them through a concentrator to put them onto a single fiber or cable. The paper will also discuss alternative architectures and how ARINC 818 can be utilized with legacy systems.
