Self configuring multi-dwelling satellite receiver system
First Claim
1. In a receiver for a DBS (digital broadcast satellite) system, an automatic configuring method of implementing multi-dwelling reception and normal reception comprising the steps of:
- a) receiving an intermediate frequency signal from a DBS antenna unit;
b) detecting whether the intermediate frequency signal is in a multi-dwelling format or a normal format by tuning to an upper band of the intermediate frequency signal;
c) if the multi-dwelling format is detected in step b), configuring the receiver for multi-dwelling reception; and
d) if the normal format is detected in step b), configuring the receiver for normal reception, wherein steps b), c), and d) are performed automatically to configure the receiver without user intervention.

Abstract
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.

11. In a receiver for a DBS (digital broadcast satellite) system, a method of implementing automatic configuration for operating with multidwelling reception and normal reception comprising the steps of:
-
a) receiving an intermediate frequency signal from a LNB (low noise down converter) coupled to a DBS antenna unit;
b) detecting whether the intermediate frequency signal is in a multidwelling format or a normal format by tuning to an upper band of the intermediate frequency signal, wherein the upper band of the intermediate frequency signal includes the range of 1450 MHz to 2050 MHz and a lower band of the intermediate frequency signal includes the range of 950 MHz to 1450 MHz;
c) if the multi-dwelling format is detected in step b), configuring the receiver for multi-dwelling reception; and
d) if the normal format is detected in step b), configuring the receiver for normal reception, wherein steps b), c), and d) are performed automatically to configure the receiver without user intervention. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)

19. A DBS (digital broadcast satellite) receiver for a DBS system including an embedded computer system having a processor coupled to a memory via a bus, the memory storing software which when executed causes the receiver to implement a method of automatic configuration for operating with multi-dwelling reception and normal reception, the method comprising the steps of:
-
a) receiving an intermediate frequency signal from a LNB (low noise down converter) coupled to a DBS antenna unit;
b) detecting whether the intermediate frequency signal is in a multi-dwelling format or a normal format by tuning to an upper band of the intermediate frequency signal, wherein the upper band of the intermediate frequency signal includes the range of 1450 MHz to 2050 MHz and a lower band of the intermediate frequency signal includes the range of 950 MHz to 1450 MHz;
c) if the multi-dwelling format is detected in step b), configuring the receiver for multi-dwelling reception; and
d) if the normal format is detected in step b), configuring the receiver for normal reception, wherein steps b), c), and d) are performed automatically to configure the receiver without user intervention. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26)
