Abstract
Systems and methods in accordance with embodiments of the invention include converting satellite signals to an intermediate frequency signal for content decoding, and selecting modulated digital data within the satellite signals for content decoding using digital signal processing. One embodiment includes a system configured to select at least one content channel from an input signal including a plurality of content channels modulated onto a carrier, the system including: a digital channelizer switch including: a high speed analog to digital converter configured to digitize the intermediate frequency signal; a digital channelizer configured to digitally tune a content channel from the digitized intermediate frequency signal; and a high speed digital to analog converter configured to generate an analog output signal using the content channel digitally tuned from the digitized intermediate frequency signal by the digital channelizer.
