Method and apparatus for triggering an automatic transmission

摘要

A multi-channel automatic transmission system, which is used with a number of regional transmitters, replaces functions previously performed in a network studio by a number of single channel automatic transmission systems corresponding to the number of regional transmitters. Outputs from either a computer or a manual input device are selectable by a switch to operate the system in accordance with a stored first selection of commercial messages, a manually determined second selection of commercial messages, or a manually altered selection. The duration and commencement of the commercial break is the same throughout the network but the number, duration and sequence of the commercial messages transmitted by each regional transmitter can be different.
