An audio/video network system for distributing satellite broadcast services includes an antenna unit for receiving audio/video broadcast services. The antenna unit is in communication with a master receiver, which receives the audio/video broadcast services and displays them on a first television associated with the master receiver. The master receiver is in communication with a plurality of slave clients, which receive audio/video broadcast services from the master receiver and display them on a respective television associated with each of the slave clients.

Audio/video satellite broadcast network

A method and apparatus for adaptively transmitting an uplink signal comprising information from a ground station to a satellite is disclosed. The method comprises the steps of receiving a transmitted downlink signal at a ground station from the satellite; measuring the quality of the transmitted signal; computing a prediction of a degradation of the uplink signal using the quality of the received signal, and transmitting the uplink signal according to the predicted degradation of the uplink signal. The apparatus comprises a tuner for receiving a transmitted downlink signal from the satellite; a signal analyzer, communicatively coupled to the tuner, for measuring a characteristic of the received downlink signal; an uplink degradation estimation module, communicatively coupled to the signal analyzer, for estimating the degradation of the uplink signal from the received downlink signal characteristic; and a controller, communicatively coupled to the uplink degradation module, for controlling the transmission of the uplink signal according to the estimated degradation of the uplink signal.
