Method and apparatus for triggering an automatic transmission
First Claim
1. A method of triggering an automatic transmission system so as to broadcast a plurality of selected sequences of events of video and/or audio signals, said method comprising the steps of:
- storing a first selection of said events in a control computer;
summing play durations of each of said events of said first selection to be broadcasted;
entering a second selection of said events to input means;
supplying an output signal from said control computer corresponding to said first selection to switch means when said summed play duration equals a reference duration;
supplying to said switch means an output signal from said input means corresponding to said second selection; and
operating said switch means so as to supply to said automatic transmission system an output signal corresponding to one of said first selection, said second selection and a third selection of said events, said third selection being obtained by modifying said first selection by said input means, so as to trigger the automatic transmission system and enable each of said sequences to be simultaneously broadcast over a respective one of a plurality of broadcast channels.

Abstract
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.

8. An apparatus for triggering an automatic transmission system so as to broadcast a plurality of selected sequences of events of video and/or audio signals, said apparatus comprising:
-
control computer means for storing a first selection of said events, each of said events having a predetermined play length, and for supplying an output signal corresponding to said first selection when a sum of said predetermined play lengths of said events of said first selection equals a reference length; means for entering a second selection of said events and for supplying an output signal corresponding thereto; switch means for receiving the output signals from said means for entering and said control computer means and for supplying a signal corresponding to one of said first selection, said second selection and a third selection of said events, said third selection of events being obtained by modifying the output signal corresponding to said first selection of said events, to said automatic transmission system so as to trigger the same and enable each of said sequences to be simultaneously broadcast over a respective one of a plurality of broadcast channels. - View Dependent Claims (9, 10, 11)
