Analog video to ARINC 818

Abstract

Many commercial and military aircraft still use analog video, such as RS-170, RS-343, or STANEG 3350. Though the individual digital components many be inexpensive, the cost to certify and retrofit an entire aircraft fleet may be prohibitively expensive. A partial or incremental upgrade program where analog cameras remain in use but data is converted and processed digitally can be an attractive option. This paper describes Great River Technology's experience in converting multiple channels of RS-170 and multiplexing them through a concentrator to put them onto a single fiber or cable. The paper will also discuss alternative architectures and how ARINC 818 can be utilized with legacy systems.

Design of Aeronautical Digital Video and Communication Bus Processing System

“…The FPGA is manufactured using a 28nm process, and power consumption can be reduced by half compared with a similar density of 40nm devices. FPGA utilizes its abundant logic resources and IP core resources and cooperates with corresponding peripheral auxiliary circuit modules to construct a flexible and reconfigurable bus interface processing system [10][11][12] .…”
