Abstract
Abstract A method of transmitting addressed messages to subscribers comprises the steps of defining the group or individual subscriber to be addressed, creating the message, assigning the message to the individual or group to be addressed, scheduling the message for transmission, transmitting the message, and recording the transmission of the message. The message creating step further includes the steps of defining message attributes such as background color, creating sets of instructions for the subscriber, if required, setting a data field related to alerting the subscriber and compressing the data length of the message using a predetermined compression code. A system control computer, according to the present invention, comprises a billing computer interface for interfacing with a billing computer and a user interface for providing access to messaging services to a system operator, each of the billing and user interfaces for providing data to a group queuing subsystem and a system event scheduler, respectively. The user interface further accesses a database, the database shared by the system event scheduler and a message, device and group manager. The device manager in turn, when scheduled by the system event scheduler, coordinates the transmission of addressed messages via either a headend controller (via an inband channel) or an addressable data transmitter (via an out-of-band channel).
