SYSTEM FOR PROCESSING A SCRAMBLED VIDEO SIGNAL INCLUDING A NOISE SUPPRESSION CIRCUIT WHICH CAN BE INHIBITED |
摘要 |
A television receiver receives a scrambled television signal with a suppressed sync pulse which is restored by a decoder coupled to the receiver. The receiver also includes a noise inverter which alters blanking interval noise pulses below a threshold level to prevent the noise pulses from disrupting the operation of other receiver circuits. The operation of the noise inverter is inhibited when the decoder is operative in the presence of a scrambled signal. |
