What is ARINC 818?

ARINC 818 is a high-speed, low-latency, video and data protocol specification optimized for live video. This standard is widely used in the mil/aero industry for video and other avionics data transmission within aircraft systems such as high-resolution displays, sensors, and processors. ARINC 818 was developed to provide more efficient communication and address the increasing demand for higher bandwidth in modern avionics systems. The flexibility, timing control, switching capability, and reliability of ARINC 818 make it an excellent choice for the central video backbone of modern avionics and mission systems.

The ARINC 818 protocol is physical media independent; systems typically use fiber optic cable, but another option is copper, including bidirectional coax.

Video parameters are customized by the user in the Interface Control Document (ICD) for individual links including; link rates from 1X (1.0625 Gbps) to 32X (28.05 Gbps), pixel packing method, video timing class, line and frame timing, and/or embedded data. ARINC 818 can be used to transmit single and multiple video streams, distribute a single video stream over multiple links, or provide switching capabilities. The depth of customization in video parameters and flexibility with supported functions allow ARINC 818 to be used in a variety of projects.

Beyond its versatility in customization, ARINC 818 also emphasizes stringent accuracy measures. Two available levels of cyclical redundancy checks (CRC), one level required on each ADVB packet and an optional level on the entire image, provide a check of accuracy to aid in rigorous certification processes. ARINC 818 is suitable for mission-critical applications up to the highest level of aviation safety certification, DAL A.
