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. For example, the operator of the first communication device may view a spectrum analysis of communication signals being routed to, processed by, and/or provided by the second communication device, or group of second communication devices, to diagnose the performance problems, or the potential performance problems, in real time.

摘要： A receiver portion includes a bandpass filter (e.g. SAW filter) that performs channel selection from an input signal having a plurality of channels, and an image cancellation circuit that is in parallel with the bandpass filter. The bandpass filter performs channel selection to select a desired channel that falls in a passband of the bandpass filter. Since the passband is typically a few channels wide, the image channel falls outside the passband and is attenuated by the stopband attenuation of the bandpass filter. The image cancellation circuit includes an attenuator and a phase shifter. The attenuator is configured to have the same attenuation as the stopband attenuation of the bandpass filter at the image channel frequency, and phase shifter is configured to provide a phase shift of approximately 180 degrees. Therefore, the image cancellation circuit has an output that is equal in amplitude, but opposite in phase, to that of the bandpass filter at the image channel frequency. A summer combines the output of the image cancellation circuit with the bandpass filter output to further suppress the image channel frequency over that achieved by the bandpass filter alone.

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 direct sampling tuner includes a low noise amplifier and an optional dynamically configurable band pass filter coupled to the low noise amplifier. The optional filter is configured to pass a selected band of channels. The tuner further includes a relatively high accuracy, multi-bit analog-to-digital converter ("ADC") coupled to the LNA or to the optional dynamically configurable band pass filter. The ADC operates at greater than about twice a frequency of a sampled signal. The ADC directly samples the spectrum of the selected channels at the Nyquist frequency, thus avoiding image problems presented by conventional tuners.
