Broadcast system for a facility
First Claim
1. A broadcast system for a facility, said system including:
- means for producing each of a plurality of broadcast signals including a program signal, a supervisory program signal and a supervisory alert signal;
a supervision controller for said broadcast signals;
power supply means having output terminals on which there appears a desired power supply for monitoring stations;
means for combining said program signals with said power supply to form an output signal suitable for broadcast within said facility;
bus means for distributing said output signal in said facility to each of a plurality of monitor stations; and
said plurality of monitoring stations each including;
(a) means connected to said bus means to recover broadcast signals and form a resident power supply for that monitor station only from said output signal,(b) a monitor coupled to a resident amplifier and powered by said resident power supply for responding to any of said plurality of recovered broadcast signals,(c) a resident controller for controlling said resident amplifier when receiving a program signal supplied to said monitor, and(d) a resident executive controller for overriding said resident controller and applying said supervisory alert signal and supervisory program signal to said resident amplifier.

Abstract
A broadcast system for a facility including audio and video signal generators that may also include the audio output of a microphone for forming broadcast signals. The broadcast signals include a program signal, a supervisory program signal and a supervisory alert signal. The power supply for monitoring stations and broadcast signals are combined to form an output signal that is broadcasted throughout the facility. A bus distributes the output signal in the facility to each of a plurality of monitor stations. Each monitor station includes decoders to recover the audio and video signals and form a resident power supply for that monitor station only from the output signal on the bus. The monitor could also includes a video monitor and speaker coupled to the resident amplifier to the resident power supply for responding to any of the broadcast signals. A resident controller controls the resident amplifier when receiving a program signal supplied to the monitor. A resident executive controller disables the resident controller and applies a recovered supervisory alert signal and supervisory program signal to the resident amplifier.
