Abstract

See full text

In a receiver for a DBS (direct broadcasting satellite) system, a method of implementing multi-dwelling reception and normal reception. The method is implemented in receiver. The receiver of the present invention is capable of setting itself up for use with a DBS antenna unit and LNB without any intervention from the user. The present invention automatically configures itself for operation with either right-hand circular polarized signals or left-hand circular polarized signals as received from the antenna unit and LNB. The DBS system includes an antenna unit for receiving the DBS signal from the DBS satellite. The DBS signal is converted to a DBS IF (intermediate frequency) signal and is coupled to the receiver. The receiver receives the DBS IF signal and detects whether the IF signal is in a multi-dwelling format or a normal format by tuning to an upper band of the IF signal. If the multidwelling format is detected, the receiver configures itself for multi-dwelling reception. If the normal format is detected, the receiver configures itself for normal reception. The steps of receiving the DBS IF signal, detecting whether the IF signal is in a multi-dwelling format or a normal format, and configuring for multi-dwelling reception or normal reception are performed by the receiver automatically such that the receiver properly configures itself for operation without user intervention.
