Abstract
Abstract The present invention includes a method and apparatus for broadcast distribution of messages and information. Included within the present invention are means for selectively broadcasting messages to specified locales. Further, only the appropriate receiver within that locale operates to receive the message. At the receiver, the message is transmitted to or receivable by the appropriate recipient. In the event that a message is inadvertently lost or transmitted with noise induced errors means are provided for requesting a retransmission of the message.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
167 words
A broadcast distribution network of the type which includes host sending means for distributing a plurality of messages to a plurality of users, each of said users having a specific predefined address, said network comprising: a plurality of receivers, each receiver having a plurality of users; a sequence number; means for generating the sequence number of each massage corresponding to the receiver intended to receive the message, wherein each sequence number is sequentially generated to represent a count of the number of messages sent to that receiver; means for sending the sequence number with its corresponding message from the host to the receiver; means for storing the sequence number and its corresponding message in the host for each of the receivers; means for storing the sequence number by each receiver for itself by replacing a previously received sequence number; means for comparing the sequence number to the previously received sequence number for determining whether each message sent by the sending means has been received by the receiver.
Claim 2
Dependent Claim
167 words
A broadcast distribution network of the type which includes host sending means for distributing a plurality of messages to a plurality of users, each of said users having a specific predefined address, said network comprising: a plurality of receivers, each receiver having a plurality of users; a sequence number; means for generating the sequence number of each massage corresponding to the receiver intended to receive the message, wherein each sequence number is sequentially generated to represent a count of the number of messages sent to that receiver; means for sending the sequence number with its corresponding message from the host to the receiver; means for storing the sequence number and its corresponding message in the host for each of the receivers; means for storing the sequence number by each receiver for itself by replacing a previously received sequence number; means for comparing the sequence number to the previously received sequence number for determining whether each message sent by the sending means has been received by the receiver.
Claim 3
Dependent Claim
23 words
The network according to claim 1 further comprising means within the sending means for resending the previous message which has not been received.
Claim 4
Dependent Claim
27 words
The network according to claim 2 further comprising means within the receiver means for transmitting a request signal to activate the means for resending a previous message.
Claim 5
Dependent Claim
28 words
The network according to claim 3 wherein the means for transmitting the request signal does so automatically upon the detection that a sent message has not been received.
Claim 6
Dependent Claim
34 words
The network according to claim 4 wherein the sending means sends each message a predetermined number of times and the receiver means further comprises suppression means for ignoring messages which have already been received.
Claim 7
Dependent Claim
14 words
The network according to claim 5 further comprising means for overriding the suppression means.
Claim 8
Dependent Claim
37 words
The network according to claim 1 wherein the sending means includes a plurality of commercial, frequency modulated radio stations and means for transmitting the messages on subcarrier frequencies of the main frequencies assigned to the radio stations.
Claim 9
Dependent Claim
15 words
The network according to claim 7 wherein each receiver means include a frequency modulated receiver.
Claim 10
Independent Claim
150 words
A method for distributing a plurality of messages form a host to a plurality of users at one or more receivers over a broadcast distribution network, wherein each of said users has a specific predefined address, said method comprising the steps of: generating a sequence number for each message corresponding to a receiver intended to receive the message, wherein each sequence number is sequentially generated to represent to a count of the number of messages sent to that receiver; sending each sequence number with its corresponding message from the host to the receiver; storing the sequence number and its corresponding message in the host for each receiver; storing the sequence number in each receiver for itself by replacing a previously received sequence number; and comparing the sequence number to the previously received sequence number for determining whether each message sent by the sending means has ben received by the receiver.
Claim 11
Independent Claim
150 words
A method for distributing a plurality of messages form a host to a plurality of users at one or more receivers over a broadcast distribution network, wherein each of said users has a specific predefined address, said method comprising the steps of: generating a sequence number for each message corresponding to a receiver intended to receive the message, wherein each sequence number is sequentially generated to represent to a count of the number of messages sent to that receiver; sending each sequence number with its corresponding message from the host to the receiver; storing the sequence number and its corresponding message in the host for each receiver; storing the sequence number in each receiver for itself by replacing a previously received sequence number; and comparing the sequence number to the previously received sequence number for determining whether each message sent by the sending means has ben received by the receiver.
Claim 12
Dependent Claim
17 words
The method according to claim 9 further comprising resending the previous message which has not been received.
Claim 13
Dependent Claim
21 words
The method according to claim 10 further comprising transmitting a request signal to activate the means for resending a previous message.
Claim 14
Dependent Claim
22 words
The method according to claim 10 further comprising automatically transmitting a request signal to activate the means for resending a previous message.
Claim 15
Dependent Claim
28 words
The method according to claim 12 further comprising sending each message a predetermined number of times and ignoring messages which have already been received with a suppression means.
Claim 16
Dependent Claim
12 words
The method according to claim 13 further comprising overriding the suppression means.
Claim 17
Dependent Claim
25 words
The method according to claim 9 further comprising transmitting the messages on subcarrier frequencies of the main frequencies assigned to the frequency modulated radio stations.
Claim 18
Dependent Claim
16 words
The method according to claim 15 further comprising receiving each message with a frequency modulated receiver.
