Digital Signal Distribution in a Combined Digital/Analog Environment

This paper deals with all aspects of multiple signal distribution and interconnection within Crawford Communications. The signals discussed are audio and video both in the analog and digital domain as well as the associated control system. Because the facility is spread across four buildings all using different video formats many challenges had to be overcome. These challenges include signal distribution over long distances, overcoming different ground potentials in different buildings, the need for a common control system for all routing systems, and signal conversion between different formats. Because many signals must travel large distances between buildings some signals are sent via serial digital connections and some are sent via the analog and EQ distribution amplifier method. The advantages and costs of both methods are discussed. Signal formatting and conversion between different formats using a common control system was a must to complete the project. This signal conversion is done using router control among multiple routing systems.
