Abstract:
1. A television receiver for processing television signals to provide video and audio information for a desired television channel signal, the television signals being transmitted according to a variety of television broadcast standards, wherein the television receiver comprises: an analog processing block for filtering and amplifying a multi-channel television signal to produce a coarse channel signal; an analog to digital converter (ADC) coupled to the analog processing block for digitizing the coarse channel signal to produce a digitized coarse channel signal; and a digital processing block coupled to the ADC for processing the digitized coarse channel signal to obtain the video and audio information for the desired television channel signal, wherein for analog and digital television broadcast standards, the processing comprises re-sampling a processed version of the digitized coarse channel signal at a first new sampling rate, with respect to a sampling rate employed by the ADC, to adjust a normalized bandwidth of the desired television channel signal to generally correspond to a normalized passband of a video filter; wherein for analog television broadcast standards the digital processing block is further configured to re-sample the processed version of the digitized coarse channel signal at a second new sampling rate to adjust a normalized bandwidth of the audio information of the desired television channel signal to generally correspond to a normalized passband of an audio filter; wherein the digital processing block comprises: wherein the video processing block comprises:
