Patent US 4,887,308

An information storage and retrieval system is disclosed herein having a primary information storage for broadcast information that is selected and encoded for constant broadcast transmission. Such information may take the form of musical compositions including title, composer, artist data and the like. An emergency transmission network selectively transmits pre-set emergency information or data. A receiver is employed to receive both broadcast and emergency transmissions and decode the information for presentation on a visual display with emergency display superseding the broadcast display. A broadcast data hold and recall manual buttons are employed to store desired data in a memory and to subsequently recall such data at the command of the listener.
