ARINC 818
ARINC 818: A video interface and protocol standard called Avionics Digital Video Bus (ADVB) was created for avionics systems that require high bandwidth, low latency, and uncompressed digital video transmission.
Since its January 2007 introduction, ARINC and the aerospace community have worked to enhance the standard to satisfy the demanding requirements of high-performance digital video.
Following an upgrade to the specification, ARINC 818-2 was published in December 2013 with several new capabilities, such as bi-directional control, channel-bonding, switching, field sequential color, link rates up to 32X fiber channel rates, and data-only links.
In 2018, ARINC 818-3 was made available. This update addressed a number of bugs and highlighted the differences between the 8b/10b and 64b/66b encoding rates.
ARINC 818 Protocol
A point-to-point serial protocol for data, audio, and video transmission, ARINC 818 (Avionics Digital Video Bus) is 8b/10b encoded (or 64B/66B for faster speeds).
While packetized, the protocol is video-centric and highly adaptable, enabling a variety of intricate visual tasks such as transmitting a single stream over a dual connection or multiplexing multiple video streams over a single link.
ARINC 818 – 2 – In order to handle faster link rates, networking, encryption and compression, and advanced display systems including channel bonding for large area displays (LADs), ARINC 818-2 was ratified in December 2013.
ARINC 818 – 3 – For dependable high-speed video transmission, ARINC 818-3 adds established latency budgets, enhanced encoding, and larger data rates.
High-bandwidth sensors, VR cockpits, and 4K/8K displays are just a few of the next-generation aerospace applications that it powers.
