Abstract
A cable television video messaging system for selectively overlaying or substituting a desired input message, for example an Emergency Broadcast System warning, onto multiple channels of a cable television system having a headend system where multiple external program signals are channelized by means of individual channel modulators. This achieved by a digital microprocessor powered message-management unit programmed to talk to a network of channel message units, one for each channel. Preferably the channel message units are also microprocessor powered and include character generator and channel synchronizer chips. General supervision of a cable television system's analog domain program distribution system by digital means is also possible.
