Distribution and Routing of Digital HDTV Signals in the Production Plant

This paper investigates the technical requirements for distributing 1.5Gb/s digital signals in a typical production facility. It covers router architectures, relocking methods, cable characteristics and equalization, distribution amplifiers, and fiber optic interconnects. — It looks at expandable and non-expandable routers and focuses on the technical requirements to build a reliable expandable switch at these high data rates. The paper tabulates distance limitations of coaxial cable at 1.5Gb/s and shows how fiber optic cable can be used cost effectively for longer runs.
