Conditional access system for satellite outdoor unit
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.

Signal Distribution System Cascadable AGC Device and Method
A cascadable AGC amplifier in a signal distribution system includes a low noise cascadable amplifier having a through path and a cascadable output. The cascadable amplifier is also configured to provide AGC over a predetermined input power range. The cascadable AGC amplifier can be configured to provide gain or attenuation. When the cascadable AGC amplifier is implemented in a signal distribution system, typically as part of a signal distribution device, an input signal can be gain controlled and supplied to multiple signal paths without distortion due to degradation of signal to noise ratio or distortion due to higher order amplifier products. The distributed signal is not significantly degraded by distortion regardless of the number of cascadable AGC amplifiers connected in series or the position of the cascadable AGC amplifier in the signal distribution system.

SYSTEM AND METHOD FOR AVOIDING DISEQC CONFLICTS
Method for avoiding DiSEqC conflicts in a receiver connected to a coaxial cable wherein the receiver utilizes the Unicable communication, the method being characterized in that it comprises the steps of: obtaining a list of an identified group of receivers, the group being organized according to an identified order; using a second communication channel (102) to communicate with at least one other receiver from said identified group; receiving a token over the second communication channel (102); transmitting a DiSEqC command over the Unicable bus only when said token has been received; after executing said DiSEqC command (405), transmitting said token, over the second communication channel (102), to the next receiver identified by said order.
Tuner device
Disclosed is a tuner device including an input terminal, a separator, a first amplifier, a second amplifier, and a tuner. The input terminal receives an input of a reception signal of satellite digital broadcasts. The separator is connected to the input terminal and adapted to frequency-separate a first signal and a second signal. The first signal is in a low-frequency domain of the reception signal, and the second signal is in a high-frequency domain of the reception signal. The first and second amplifiers respectively amplify the first and second signals. The tuner receives an input of output signals from the first and second amplifiers.
