APPARATUS FOR DECODING SCRAMBLED TELEVISION AND SIMILAR TRANSMISSIONS |
摘要 |
<p>APPARATUS FOR DECODING SCRAMBLED TELEVISION AND SIMILAR TRANSMISSIONS This disclosure deals with a novel scrambled television decoding system for modulation-suppressed trains of synchronizing signals at a predetermined line rate, in which the demodulating circuits produce an advanced modulation frequency signal synchronized with a selected reference first equalizing pulse to control the gain of the received scrambled television signals and corrspondingly to restore the suppressed synchronizing signals to reconstitute the unscrambled television signal.</p> |
