Apparatus and method for broadcasting priority rated messages on a radio communications channel of a multiple transceiver system
First Claim
1. Apparatus in a transceiver for broadcasting priority rated messages on a channel shared by a multiplicity of similar transceivers, comprising:
- analog-to-digital convertor means for generating a new message in digitalized format corresponding to audio frequency message signals in analog format applied to said convertor means;
memory means connected to said convertor means for storing said digitalized new message;
message coding means;
central data processing means connected with and controlling said coding means, convertor means and memory means, and for adding a priority rating code, a recipient identity code and a sender'"'"'s identity code to said new message;
message reception means for monitoring said channel to detect other messages broadcast one at a time thereon by others of said transceivers;
coding comparator means connected to said message reception means and said data processing means for comparing the priority rating of each of said other messages with the priority rating of said new message; and
message broadcast means connected to said memory and under control of said data processing means for broadcasting said new message only when said channel is clear of any other message of equal or higher priority than that of said new message, and permits said new message to interrupt the broadcast of any other message of lower priority rating than that of said new message and interrupts said new messages when broadcast starts of any other message of higher priority than that of said new message; and
said interrupted message is rebroadcast in its entirety when broadcast of the last named other message of higher priority is completed;
whereby the possibility of any two messages being simultaneously broadcast with consequent loss of intelligibility, is eliminated.

Abstract
Apparatus in a transceiver for broadcasting priority rated messages on a channel shared by a multiplicity of similar transceivers, converts an analog audio frequency message to compressed digitalized format which is stored, encrypted, and encoded with a priority rating and recipient identity code. A central data processor prevents broadcast of the message while any other message of higher priority rating is being broadcast, or interrupts broadcast of the message when broadcast of another message of higher priority is detected, or interrupts broadcast of any other message of lower priority than that of a message waiting to be broadcast. Received messages bearing the recipient'"'"'s identity code are stored and played back in order of their priority rating.

9. In a transceiver transmitting and receiving messages broadcast one at a time on a radio frequency channel by a multiplicity of transceivers, wherein each of said messages has a compressed format and includes coding indicating the intended recipient of the message and a priority rating assigned to said message, apparatus comprising:
-
receiver means for receiving said messages; code identification means connected to said receiver means for identifying the assigned priority of each of said received messages by said receiver means; first message storage means connected to said receiver means for storing messages. second storage means connected to said first storage means for storing only those messages intended for reception by said receiving means; playback means connected to said second storage means for playing back said stored messages; and message data processing means connected to said first storage means for identifying which of said received messages are intended for reception by said receiver means; and
wherein said data processing means is also connected to said second storage means for permitting the messages intended for reception to be stored therein and connected to said code identification means and said playback means and programmed to playback said messages stored in only said second storage means in the order of their assigned priority rating and regardless of the numerical order in which they were received. - View Dependent Claims (10, 11, 12)
