Abstract
A cable ready television receiver includes a set back decoder that communicates with the microprocessor in the television receiver via its own microprocessor. A synchronous demodulator in the television receiver is operated normally for unscrambled television signals and is operated to quadrature demodulate scrambled television signals. The quadrature demodulation develops only high frequency video, modulated chroma, FM modulated audio and DC. The demodulator output is applied to the audio circuit and to the AGC circuit in the television receiver. A descrambler in the decoder develops the video signal for application to the video circuitry in the television receiver.
