    摘要： A method and apparatus is disclosed to restrict the delivery of video, audio, and/or data to unauthorized end users in a satellite communications system. The satellite communications system includes one or more satellite receiving antennas, commonly referred to as a satellite dish, to receive downlink communications signals from one or more satellites. The transmission received by the one or more satellite receiving antennas is converted by an outdoor unit (ODU) for transmission to one or more indoor units (IDUs). The ODU receives control information from one or more satellites from the downlink communications signals, commonly referred to as in-band, and/or from out-of-band communications signals. The ODU may use the control information to restrict access to one or more communications channels embedded within the downlink communications signals to the unauthorized end users.

    摘要： A system, method, and apparatus to allow an operator of a broadcast communication system, such as a cable television or satellite television service to provide some examples, to diagnose performance of this communication system remotely. The operator of a first communication device, such as a cable modem termination system (CMTS) to provide an example, may remotely diagnosis performance problems, or potential performance problems, occurring at a second communication device, such as a cable modem (CM) to provide an example, or a group of second communication devices.

    摘要： In an embodiment, a receiver for processing a RF input signal having a variable signal strength includes an RF amplifier, an IF amplifier, and a controller. The RF amplifier is configured to receive and amplify the RF input signal. The IF amplifier is coupled to an output of the RF amplifier. The controller controls gains of the RF amplifier and the IF amplifier during times of falling signal strength. A gain of the IF amplifier is increased as the signal strength falls until a first amplitude threshold is reached for the falling signal strength. If the signal strength falls beyond the first threshold, a gain of the RF amplifier is increased until a second amplitude threshold is reached. The second amplitude threshold is lower than the first amplitude threshold. If the signal strength falls below the second amplitude threshold, the gain of the IF amplifier is further increased.

    摘要： An apparatus and method is disclosed to calculate the actual received desired channel power from the downstream transmit power of a Cable Modem Termination System (CMTS) when operating at the nominal line voltage and/or at the normal room temperature as per the DOCSIS specification. A Set-top Device produces a Downstream Power Management (DPM) gain measurement signal having a known power level. The Set-top Device embeds the DPM gain measurement signal onto a received downstream multi-channel communication signal. After embedding the DPM gain measurement signal onto the downstream multi-channel communication signal, the Set-top Device downconverts the combined DPM gain measurement signal and downstream multi-channel communication signal to recover one or more communication channels containing information of a broadcast. The Set-top Device measures a power level of a representation of the DPM gain measurement signal embedded within the one or more communication channels containing the information of the broadcast to determine a Set-top Device gain. The Set-top Device measures a power level of the one or more communication channels containing the information of the broadcast. The Set-top Device calculates the actual received desired channel power from the downstream transmit power of the CMTS based on the Set-top Device gain and the power level of the one or more communication channels containing the information of the broadcast.

    摘要： A varactor folding technique reduces noise in controllable electronic oscillators through the use of a series of varactors having relatively small capacitance. A folding circuit provides control signals to the varactors in a sequential manner to provide a relatively smooth change in the total capacitance of the oscillator. Consequently, effective control of the oscillator is achieved with accompanying reductions in oscillator noise such as flicker noise.
