许多商用和军用飞机仍然使用模拟视频，如RS-170、RS-343或STANEG 3350。虽然单个数字组件可能不贵，但认证和改造整个机队的成本可能非常昂贵。一个部分或增量升级计划，其中模拟相机仍然使用，但数据转换和数字处理可能是一个有吸引力的选择。本文介绍了大河技术公司在转换多个RS-170通道并通过集中器将它们多路复用到一根光纤或电缆上的经验。本文还将讨论替代架构以及ARINC 818如何与遗留系统一起使用。
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.
