A system for processing signal communications between a frequency translation module and an integrated receiver decoder. According to an exemplary embodiment, the decoder and the frequency translation module comprise a signal processing apparatus comprising an input for receiving an frequency shift keyed modulated signal, an amplifier having negative feedback coupled to said input, wherein said input is further coupled to a first source of reference potential and a second source of reference potential; and a tank circuit coupled between said differential amplifier and an output. More particularly, the amplifier may comprise a first transistor having a first collector, a first emitter and a first base coupled to a signal source wherein said first base is further coupled to said first collector and a second transistor with a second base, a second emitter coupled to said first emitter, and a second collector, wherein said second collector is coupled to a bandpass filter and said bandpass filter is further coupled to an output.

An architecture for processing signal communications between a frequency translation module and an integrated receiver decoder. According to an exemplary embodiment, the signal processing apparatus comprises a demodulator for generating a first signal responsive to an FSK signal, said first signal comprising a varying amplitude and a clamping means for generating a second signal, wherein said second signal has a first value when the amplitude of the first signal is above a predetermined value, and wherein said second signal has a second value when the amplitude is below a second predetermined value.

The present invention concerns a method and apparatus for setting a frequency reference in an integrated receiver decoder (IRD). More specifically, the present invention discloses an electrical circuit arrangement in which the voltage controlled crystal oscillator (VCXO) is set to oscillate at the desired frequency prior to the initial use thereof and that frequency is stored in a non-volatile memory unit. Upon initial use, the IRD receives a data signal corresponding to a frequency reference. The IRD uses a threshold value to compare the frequency reference of the incoming data signal with the frequency stored in the non-volatile memory. If the frequencies differ by a predetermined value, the frequency from the incoming data signal is stored in the non-volatile memory and is used to set the VCXO.

The present invention relates to system diagnostic circuitry for antenna systems with active antenna components. More specifically, the present invention discloses an apparatus comprising a connection between an antenna and a power supply conducting a first DC voltage, a source of a pulse width modulated signal, a lowpass filter for converting the pulse width modulated signal to a second DC voltage, and a comparator for comparing the first DC voltage and the second DC voltage and generating an output signal responsive to the difference between the first DC voltage and the second DC voltage.

Hacking of a class of Set-Top Boxes known as Integrated Receiver-Decoders (IRDs) used to receive satellite broadcasts for display on television sets is prevented by use of connections to the reprogramming enable pin of a flash memory. If a user attempts to reprogram the boot sector of the flash memory in order to obtain free service via privacy, the set-top box is destroyed. The invention relates to the design and manufacture of IRDs that are resistant to hacking via unauthorized reprogramming.

A power supply for a satellite receiver system includes a dual input supply voltage arrangement. When a higher output voltage is selected, a source of a lower supply input voltage is coupled to an input main current conducting terminal of a series pass transistor. 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 senses a magnitude of an output voltage 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, any selection of the higher output voltage is automatically overridden and the source of the lower supply input voltage, instead, is coupled to the input main current conducting terminal of the series pass transistor.
