ABSTRACT:
A communications system has a single transmitter and a large number of portable receivers. The transmitter broadcasts a continuous stream of coded text messages, each addressed to a particular user or group of users. Each receiver demodulates all the messages, compares their addresses with a list of addresses in the receiver, and stores only those messages having one of the proper addresses. The user can activate the receiver to play back messages in the memory, and to choose among the stored messages. The messages selected for playback are converted from digital text to a synthesized voice, sent as an audio signal to the user.
