What is Avionics Digital Video Bus mean?

ARINC 818: Avionics Digital Video Bus (ADVB) is a video interface and protocol standard developed for high bandwidth, low-latency, uncompressed digital video transmission in avionics systems. The standard, which was released in January 2007, 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 818-2 was released in December 2013, 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.

ARINC 818-3 was released in 2018. This revision clarified the 8B/10B encoding rates versus the 64B/66B encoding rates, along with clarifying several issues.

Although simplired, ADVB retains attributes of Fibre Channel that are beneficial for mission-critical applications:High Speed / High Reliability / Low Latency / Flexibility / High-Performance / Uncompressed Digital Video Transmission
