ARINC 818
ARINC 818: Avionics Digital Video Bus (ADVB) is a video interface and protocol standard developed for high bandwidth, low latency, uncompressed digital video transmission in avionics systems. The standard, which was released in January 2007, has been advanced by ARINC and the aerospace community to meet the stringent needs of high performance digital video. The specification was updated and ARINC 818-2 was released in December of 2013, adding a number of new features, including link rates up to 32X fibre channel rates, channel-bonding, switching, field sequential color, bi-directional control, and data only links.
==Background==
In aircraft, an ever-increasing amount of information is supplied in the form of images, this information passes through a complex video system before reaching cockpit displays. Video systems include: infrared and other wavelength sensors, optical cameras, radar, flight recorders, map/chart systems, synthetic vision, image fusion systems, heads-up displays (HUD) and heads-down primary flight and multifunction displays, video concentrators, and other subsystems. Video systems are used for taxi and take-off assist, cargo loading, navigation, target tracking, collision avoidance, and other critical functions.
ARINC 818/ADVB is a Fibre Channel (FC) protocol that builds on FC-AV (Fibre Channel Audio Video, defined in ANSI INCITS 356-2002), which was used extensively on video systems in the F-18 and the C-130AMP. Although FC-AV has been used on numerous programs, each implementation has been unique. ARINC 818 provides an opportunity to standardize high-speed video systems and has since been adopted by a number of high-profile commercial and military aerospace programs, including the A400M, A350XWB, B787, KC-46A, COMAC-919 and numerous other programs. ARINC 818 is also common in avionics suites, such as Proline Fusion by Rockwell Collins, the TopDeck by Thales.
