Overview of ARINC 818 Supplement 2

In 2005, Airbus and Boeing introduced an effort to further capabilities for the new 787 and A400M programs, and a new standardization effort was initiated through the Digital Video Subcommittee of ARINC.

The aim of the ARINC 818 specification was to provide a robust protocol to handle the high-bandwidth of modern avionics video systems and include the precise timings for line synchronous displays. ARINC 818 was based on the Fiber Channel Audio Visual (FC-AV) specification but drastically reduced the complexity.

Fiber Channel remains the physical layer for the bus and also offers the advantages of routing and protocol capabilities found in modern networking.

FC also is deterministic with low latency.

ARINC 818 includes additional container error detection.
