Satellite communications network
First Claim
1. A satellite communications network, comprising(a) encoder means for encoding a composite signal including message, addressing and command information, said encoder means including(1) a data base manager containing programming and data distribution information and producing a distribution signal;
- and(2) an encoder controller connected with said data base manager for generating a data stream containing message, addressing, and command information in accordance with said distribution signal;
(b) transmitter means connected with said encoder means for transmitting said encoded signal to a satellite;
(c) a plurality of receiver means responsive to said addressing information for receiving at least a portion of said encoded signal from said satellite in accordance with said distribution signal at a remote location from said transmitter means;
(d) decoder means connected with said receiver means for decoding said received portion of said encoded signal, said decoder means including a controller comprising a microprocessor which responds to addressing and command information from said composite signal to produce a control signal; and
(e) recorder means connected with said microprocessor for recording message information from said decoded signal in response to said control signal.

Abstract
A satellite communication network includes an encoder for encoding a signal including message, addressing, and command information and a transmitter connected with the encoder for transmitter the encoded signal to a satellite. The message information may comprise video and/or audio information. A plurality of receivers located at a remote location from the transmitter are operable to receive selected portions of the encoded signal from the satellite in response to the addressing information contained in the encoded signal. A decoder is connected with each receiver for decoding the received portion of the encoded signal. The decoder includes a control device which is operable to control peripheral recording devices including one or more video tape recorders and a printer to record the video information from the decoded signal in response to command information contained in the encoded signal. The satellite communications system according to the invention provides an automatic system for downlinking and recording programming during low usage times for subscribing television stations.
