ARINC 818 is unidirectional, and does not require handshaking.

FactSnippet No. 1,625,591

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

FactSnippet No. 1,625,592

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

FactSnippet No. 1,625,593

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

FactSnippet No. 1,625,594

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

FactSnippet No. 1,625,595

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

FactSnippet No. 1,625,596

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.

FactSnippet No. 1,625,597

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

FactSnippet No. 1,625,598

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

FactSnippet No. 1,625,599

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.
