System for transmitting emergency broadcast messages with selectivity to radio, television, computers and smart phones

摘要

A system digitally retransmits an emergency alert message to a plurality of recipients. A specialized category of recipients, which function to combat an emergency, receive specialized instructions to coordinate and handle an emergency situation. The digitally retransmitted emergency alert message includes a specialized unique code for each of the specialized category of recipients, along with specialized instructions along with an uncoded generic public or private emergency alert message. Each of the receivers of specialized category of recipients decodes the message pertinent to that recipient upon receipt of a matching specialized code programmed within the receiver. The generic uncoded public emergency message is received by all generic devices without specialized codes. The emergency alert message is devoid of additional information which, when present, could be burdensome. This implementation is optimized to provide very rapid alerts for specific message types e.g. earthquakes.

主权项

1. An emergency alert and message delivery system comprising:
a) one or more receivers for receiving EAS signals from different sources; b) said system analyzing the emergency signal or message data evaluating a specialized category of recipients or general public in a geographic area and, said each of the specialized category recipients having a special unique code; c) said system encoding said special code in combination with an EAS message and instructions for each of specialized category of recipients according to needs for the recipient to fulfill an emergency combating function; d) said system terminating the last message for the specialized category recipient with a delimiter followed by an uncoded public emergency alert message, wherein said system distinguishing specialized category recipients and other private transmission from public transmission by code selection and Program ID usage; e) digitally retransmitting encoded emergency alert message to everyone including selected recipients or selected retransmission, in said geographic area; f) said digitally retransmitted encoded emergency alert message received and decoded by specialized category recipient receivers having equivalent specialized unique codes and each of the specialized category of recipients receiving coordinated emergency combating instructions; and g) said uncoded or publically transmitted portion of said encoded emergency alert message being received by generic basic devices without any special code; whereby said generic or public emergency alert message is free from instructions while all of said specialized category of recipients receive coordinated instructions to combat an emergency or deliver a message.
