Cable tv

[Yossarian451]

Hmm I was wondering about how to find out what kind of cable filter or scrambling. I have have seen some people's articles on this but I get quite confused as many things seem to apply. Also can you have multiple kinds of these simultaneously? I have no access to an ocilliscope or a block converter immediately. This is for completely legal interest, I was deeply wonder after seeing a few articles on this topic. I would apprecite any insight into this.

I'm interested in learning about cable and the signals it uses too, anybody got any useful anythings for us?

i'd tell you how to de-scramble the signals, but I'd probably get banned for doing so. The most popular method of scrambling tv is the "gated sync" method in which the sync pulse is transmitted on a slightly different frequency. The result is a rolling picture that's almost perfect but doesn't "tune" in. Sometimes inversion is coupled with gated sync to get that negative picture film look.

With analog cable it is possible to "descramble" the signal, however with the advent of digital cable they no longer need to scamble the signal... they simply don't send it to your location.
