Abstract

A satellite broadcast system using an airwave message signal to remotely control a signal receiver. The system includes a system manager to issue a message, a message service to broadcast the message in the airwave message signal, and a signal receiver to select a satellite and a channel of a downlink signal from the satellite carrying a desired program. The program may include audio/video, text, pictures, software, or data. In the preferred embodiment, the message service is a pager service.

Claims

1. An improved satellite broadcast system including a program source that uplinks programs to a plurality of orbiting satellites, which, in turn, downlink the programs to a plurality of earth receiving stations, wherein each earth receiving station includes a satellite receiving antenna dish for receiving said downlink programs and having position controls for azimuth and elevation that provide for the selection of a particular orbiting satellite and a feedhorn able to receive control signals to select the phase of the antenna feedhorn for their selected polarity channel of a particular downlink signal, and each receiving station further includes a satellite program downlink receiver connected to the dish and the feedhorn for tuning particular programs according to channel and time of day, the improvement comprising at each earth receiving station:

a message broadcast receiver connected to control said dish, said feedhorn, and said satellite program downlink receiver and tuned to receive a plurality of broadcast control messages for a group of more than one earth receiving station, wherein said control messages each comprise instructions for the positioning of the dish, the setup of said feedhorn, the selection of said program channel, and the selection of a time-of-day for execution of said instructions by the dish, said feedhorn, and the satellite program downlink receiver.

2. The system of claim 1, further comprising:

a message broadcast transmitter connected to communicate said control messages by radio to a plurality of message broadcast receivers with the same control message being sent to each message broadcast receiver; and

program manager means for coordinating said programs being uplinked with said control messages being separately broadcast by radio.

3. The system of claim 2, wherein:

the message broadcast receiver includes a personal pager receiver; and

the message broadcast transmitter includes a corresponding personal pager transmitter.

4. The system of claim 1, wherein:

the message broadcast receiver includes message quality means for checking control message integrity, reliability and latency, wherein means are provided for eliminating duplicate control messages and for correcting corrupted control messages.
