The Computer Control of Multiple-Bus Switchers

M. W. S. Barlow

Previous papers have described the control of single output television switchers, commonly used for transmitter booth operation, by means of a computer. Recent designs have included numerous systems, both radio and television, in which a number of busses are controlled by one computer. The increased data load, the sharing of switcher input equipment such as tape and film machines, and the requirements for emergency manual control all affect the system design. A standard software package has been adopted for both radio and television service, and the hardware is based on a modular approach permitting easy alteration to suit the requirements of individual stations.
