14 Facts About ARINC 818

ARINC 818: Avionics Digital Video Bus is a video interface and protocol standard developed for high bandwidth, low-latency, uncompressed digital video transmission in avionics systems.

ARINC 818 is a Fibre Channel protocol that builds on FC-AV, which was used extensively on video systems in the F-18 and the C-130AMP.

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, C-130, KF-X, Comac C919, and numerous other programs.

ARINC 818 is common in avionics suites, such as Proline Fusion by Rockwell Collins, and the TopDeck by Thales.

ARINC 818 is unidirectional, and does not require handshaking.

ARINC 818 specification defines a “container” as a set of ADVB frames used to transport video.

ARINC 818 lends itself to applications that require few conductors, low weight, EMI resistance, or long-distance transmission.

ARINC 818 is flexible and can accommodate many types of video and data applications.

Flexibility of ARINC 818 allows for receiver implementations using either full image buffers or just display-line buffers.

ARINC 818 intends that timing parameters such as these be captured in an ICD specific to the video system.

Authors of ARINC 818 built upon many years of combined experience of using FC to transport different video formats, and key implementation details are included in the specification, including examples of common analog formats.

Link rates: At the time the original ARINC 818 specification was ratified, the fiber-channel protocol supported link rates up to 8.

Compression and Encryption: ARINC 818 was originally envisioned as carrying only uncompressed video and audio.

Since many of the newer implementations of the ARINC 818 have multiple displays and or many channels of ARINC 818, switching has become more important.
