Frequency drift estimation for low cost outdoor unit frequency conversions and system diagnostics

A system comprising:

• an oscillator for converting at least one first signal having television programming to at least one second signal at a different frequency;
• an analog-to-digital (A/D) converter, for receiving the at least one second signal, wherein the A/D converter directly samples the at least one second signal;
• a digital signal (DSP), communicatively coupled to the A/D converter, wherein an output of the DSP determines a compensatory frequency shift to offset a frequency drift of the oscillator from the sampled at least one second signal;
• and
• a digital-to-analog converter (DAC), coupled to the DSP, the DAC including an output having the television programming signal coupled to a remotely disposed receiver via a single wire interface.

A system comprising:

• means for converting at least one first signal having television programming to at least one second signal at a different frequency;
• means for digitally sampling the at least one second signal, communicatively coupled to the converting means;
• means for processing the digitally sampled at least one second signal, communicatively coupled to the digital sampling means, wherein an output of the processing means determines a compensatory frequency shift to offset a frequency drift of the converting means using the digitally sampled at least one second signal;
• and
• a digital-to-analog converting means, coupled to the means for processing, the digital-to-analog converting means for providing an output having the television programming signal to a remotely disposed receiver via a single wire interface.

A method of processing a first signal centered at a first frequency having television programming, comprising:

• converting the first signal to a second signal having the television programming centered on a second frequency according to a frequency source;
• generating a digital data stream from the second signal;
• estimating a frequency drift of the frequency source using the generated digital data stream;
• controlling the frequency source to correct for the estimated frequency drift;
• generating an analog signal from the digital data stream;
• and
• providing the analog signal to a remotely disposed receiver via single wire interface.
