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.

Explaining ARINC 818
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.
ARINC is a specification which has become an industry standard for the transmission of uncompressed digital video. This commercial standard uses fibre channel as a point to point communications link for low latency with the ARINC defining the packetized protocol for transmission of the digital video information. It is highly flexible and can be used for a variety of on-board display systems in both commercial and military applications. The ARINC specification defines a digital video link that is used for uncompressed video data transmission. This specification enables avionics display manufacturers to choose the video format that best suits their application. Video formats can differ in their frame rates, resolution, pixel density, and interlacing techniques which drive the required data rates. Different classes of video transmission are defined, which vary from simple asynchronous to pixel synchronous video transmission which require corresponding display capabilities.
