    • An analog TV receiver implementation on DSP allows mobile platforms to view analog TV broadcasting on LCD displays. The analog television receiver includes a demodulator for demodulating a received analog television signal, an analog to digital converter for digitizing the demodulated television signal and a digital signal processor for producing display signals from the digitized television signals. The digital signal processor being programmed to search for a horizontal synchronization signal in the television signal, track the horizontal synchronization signal and search for a vertical synchronization signal in the television signal. Next the processor separates a luminance and a pair of chrominance components of the television signal and demodulates the pair of chrominance components. Red, green and blue values are constructed from the demodulated chrominance components and the luminance components. Display signals are produced from the red, green and blue values.
    • DSP上的模拟电视接收机实现允许移动平台在LCD显示器上查看模拟电视广播。 模拟电视接收机包括用于解调接收到的模拟电视信号的解调器,用于数字化解调电视信号的模数转换器和用于从数字化电视信号产生显示信号的数字信号处理器。 数字信号处理器被编程为在电视信号中搜索水平同步信号,跟踪水平同步信号并搜索电视信号中的垂直同步信号。 接下来,处理器分离电视信号的亮度和一对色度分量,并解调该对色度分量。 红色,绿色和蓝色值由解调的色度分量和亮度分量构成。 显示信号由红色,绿色和蓝色值产生。
