Abstract
Official abstract text for this publication.
A method and apparatus is disclosed to restrict the delivery of video, audio, and/or data to unauthorized end users in a satellite communications system. The satellite communications system includes one or more satellite receiving antennas, commonly referred to as a satellite dish, to receive downlink communications signals from one or more satellites. The transmission received by the one or more satellite receiving antennas is converted by an outdoor unit (ODU) for transmission to one or more indoor units (IDUs). The ODU receives control information from one or more satellites from the downlink communications signals, commonly referred to as in-band, and/or from out-of-band communications signals. The ODU may use the control information to restrict access to one or more communications channels embedded within the downlink communications signals to the unauthorized end users.
First claim
Opening claim text (preview).
What is claimed is: 1. An outdoor unit (ODU) in a satellite communication system configured to provide a digital communication signal, the ODU comprising: a network receiver, comprising: a front end module configured to: receive a communication signal, and convert the communication signal from an analog representation to a digital representation to provide modulated control information, a demodulator module configured to demodulate the modulated control information to prov…
