Abstract

A multi-regional message delivery system (100) delivers messages from a central hub (108) to a number of message transmission regions (102,104,106) for transmission of the messages therein. The central hub 108) receives messages, encodes the messages, and transmits the encoded messages in a number of message data pipes (304) in a message delivery signal (302). A satellite (122) receives the transmitted message delivery signal (302) and then transmits the message delivery signal (302) to a number of regional stations (130,132,134) located in the message transmission regions. The regional stations receive the transmitted message delivery signal (302), select at least one of the data pipes (304) in the message delivery signal (302), and transmit the encoded messages within the message transmission regions.
