Abstract:
1. An analog television receiver comprising a demodulator for demodulating a received analog television signal and producing a demodulated television signal, an analog to digital converter for processing the demodulated television signal and digitizing the demodulated television signal, thereby producing a digitized television signal, and a digital signal processor for processing the digitized television signal and producing display signals from the digitized television signal, the digital signal processor being programmed to: search for a horizontal synchronization signal in the television signal; track the horizontal synchronization signal using a delay locked loop; search for a vertical synchronization signal in the digitized television signal using the horizontal synchronization signal; separate a luminance and a pair of chrominance components of the digitized television signal; demodulate the pair of chrominance components; construct red, green and blue values from the demodulated chrominance components and the luminance components; and produce display signals from the red, green and blue values.
