Show News. Military and civilian aviation systems require high-speed video systems for cockpit displays, head-up displays, infrared and optical sensors, and flight simulators, to name a few.
Twenty-first century advances require higher bandwidths and greater flexibility. Certification requirements are strict. In the early s, after frustrating and costly integration issues involving proprietary video protocols, Airbus, Boeing, and other OEMs put their efforts into a common avionics video standard.
The challenge: how to meet ever-expanding resolution and bandwidth requirements while maintaining enough flexibility to handle nearly any video format, update rate, and color-encoding scheme.
Which Video Bus? How ARINC 818 Became the Global Standard
Even before its official release, major programs by both Airbus AM military transport and Boeing Dreamliner adopted the protocol for their critical video subsystems. Since it is now being used in military, commercial and business aircraft, many avionics vendors may need to implement the protocol in the near future to maintain compatibility. Prior to the adoption of ARINC , there was no standard for avionics video, making each new cockpit design more expensive due to proprietary video formats required by displays and video systems. For the unfamiliar, there is a learning curve associated with the FC-AV protocol and its terminology.
The standard, which was released in January , 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 was released in December , 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. 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 are used for taxi and take-off assist, cargo loading, navigation , target tracking, collision avoidance , and other critical functions.
