Velocity for Ultra-Res ARINC 818

ALBUQUERQUE, October 10, 2017—ARINC 818 cards enabling ultra high-bandwidth video systems are here.

Velocity is a new generation frame grabber, video generator, and converter capable of link rates to 12.75 gigabits per second (Gb/s). It can be factory configured for 4K and other high-resolution ICDs, for example: UHD (2160p at 30Hz) over an 8.5 Gb/s link; 2560x1080 at 120Hz over a 12.75 Gb/s link; or 1920x1080 at 180Hz over a 12.75 Gb/s link. Velocity can convert ARINC 818 in real time to or from HDMI 2.0 to simplify testing with off-the-shelf display hardware.

Velocity adds the power of a PCIe Gen 3 x8 interface coupled with two high-speed DDR3 memory banks. As with Matrix Plus cards, GRT can factory configure a single Velocity card for up to 15 ICDs.

VPA Improvement Manages Multiple Embedded Streams

ALBUQUERQUE, March 15, 2017—Great River Technology's Video and Protocol Analyzer (VPA) makes it easier to develop advanced capabilities of the ARINC 818 Avionics Digital Video Bus by adding Multi Stream capabilities.

Multi Stream empowers the VPA to tackle ARINC 818 interfaces with multiple embedded streams of high-speed video. For example, a system designer sending multiple sensor streams over a single cable can use it to study each component stream separately. Multi Stream is now a standard feature of the VPA. Upon receiving a signal with embedded stream, it identifies source IDs it recognizes. Unrecognized source IDs are listed and staged so that a designer can quickly assign a profile, and each component stream then can be individually analyzed.

GRT's VPA was introduced a decade ago as a key development tool for verifying compliance with the ARINC 818 standard, then newly introduced to meet expanding needs for high-speed, low-latency video in aviation. The flexibility of ARINC 818 and its capacity to utilize rapidly advancing technologies make it the protocol of choice for high-resolution displays, high-speed sensors, and other critical video systems.

A second generation VPA, introduced last year, added better profile management, pixel-to-data correlation, alternate language support on the GUI, and the ability to determine characteristics of an unknown source. An optional software development kit was also introduced.
