Abstract

An electronic information dissemination system electronically distributes information such as bulk mailed letters, bills, and other information from one or more sources to each of a plurality of remote stations located in homes or businesses. The system includes individually addressable receiver/decoders at each remote station. Each receiver/decoder has information processing and memory for identifying its distinct address plus a "global" address common to the plurality of remote stations in the system. Information is gathered from various sources at a centrally located data handling station which encodes the data for transmission to the remote stations. The transmission path is provided by an existing communications network such as CATV or a switched telephone system.

memory means associated with said data handling means for storing the addressed data;

signal conversion means operatively coupled to said memory means and the cable television system for converting the stored addressed data to a radio frequency signal distinct from the television signals but suitable for transmission over the cable television system;

remote receiving means coupled to said cable television system at each of the remote stations for receiving the source identification data and the personalized data packets contained in the radio frequency signal;

selector means operatively connected with said remote receiving means for identifying the source identification data under the global address and the personalized data packet under the distinct local address for the particular remote station;

data combining means associated with said selector means for combining the personalized data packet with the source identification data and generating print signals for reproducing the combination of the source identification data and the personalized data packet; and

printer means responsive to the print signals for printing the information contained in the source identification data and the personalized data and the personalized data packet under the local address of the particular remote station.

7. An information disseminating system as recited in claim 6 wherein said signal conversion means comprises means for forming a frequency shift keyed signal having first and second frequency states for representing the data being transmitted.

8. In an information dissemination system of the type for transmitting data signals over distances from a central data handling station to a plurality of remote stations via an existing communication medium, wherein the data signals include both a global message under a global code common to all of the remote stations and individual messages under distinct codes that are each unique to particular remote station, the remote stations each having apparatus for receiving and printing the messages contained in the data signals, the apparatus comprising:
