Digital Remote-Control and Monitoring System (AFRA-Bus-System) for Automation in Broadcasting Studios
Gerd Hogel, Arthur Heller · Journal of the SMPTE · 1975
Many difficulties in planning and installing remote control and automation equipment — especially concerning larger broadcasting centers — arise out of the nonuniformity and variety of control signals and devices. Usually the installed extensive cable-networks show very poor efficiency. These disadvantages can be avoided by using a serial data bus system, in which coaxial bus lines transmitting control, back indication and distribution informations are looped through all control panels and all equipment of the studio.
