摘要： An architecture and protocol enables signal communications between a frequency translation module (20) and a plurality of decoders (60) within a dwelling. According to an exemplary embodiment, the frequency translation module (20) includes a plurality of inputs (22) operative to receive a plurality of bands of television signals. A plurality of tuners (24) is connected to the inputs (22). The tuners (24) convert the bands of television signals to a plurality of intermediate frequencies. A controller (34) is operative to receive request commands for the bands of television signals from the decoders (60). Each of the decoders (60) transmits one of the request commands to the frequency translation module (20) during a separate time slot.

摘要： An RF multiple switching apparatus (12), such as one included in or coupled to a broadcast satellite signal receiver, having a plurality of multiple RF signal input ports (14A, 14B, 14C, 14D) for receiving respective ones of a plurality of RF signals, such as broadcast satellite television signals, utilizes a relative signal strength indicator, such as an automatic gain control signal, to determine the difference between the actual input signal that is present at one of the plurality of signal input ports and a false signal that appears to be present at another signal input port of the plurality of signal input ports due to the RF signal bleeding between the multiple signal input ports. During a setup configuration determination or routine (50), the switching apparatus steps through each RF signal input, extracts pertinent transmission network (such as a satellite transmission network) information, determines a relative signal strength indicator for the RF signal, and compares the obtained information. Setup data for each RF signal input is stored according to the comparison.

摘要： A power supply (10) for a satellite receiver system includes a dual input supply voltage arrangement (200). When a higher output v oltage is selected, a source of a lower supply input voltage is coupled to an input, main current conducting terminal of a series pass transistor (Q1). On the other hand, when a lower output voltage is selected, a source of a lower supply input voltage is coupled to the input main current conducting terminal of the series pass transistor. A comparator (22) senses a magnitude of an output voltage (16) produced by the series pass transistor. When, as a result of an over current condition, the output voltage is lower than a reference threshold level (22a), any selection of the higher output voltage is automatically over-ridden and the source of the lower supply input voltage, instead, is coupled to the input main current conducting terminal of the series pass transistor.
