I guess this is why they went 100% digital for TV, it is easier to hijack. I know with broadcast, as long as your signal is more powerful you can override any station.
The signal-to-noise ratio on this thread is degrading significantly.
"They" went 100% digital because vestigial-sideband AM is a noisy and wasteful method of sending video over radio waves. There's no conspiracy; you can send 3 digital channels (depending on picture resolution) in the same bandwidth where only 1 analog channel would fit.
I know with broadcast, as long as your signal is more powerful you can override any station.
What movie did you learn that from? If anything, the "capture effect" (as it is known in FM broadcast) works BETTER on digital TV than it did on analog, because two analog channels (or noise sources) would superimpose on the video image. Ever seen interference from a nearby CB transmitter on analog TV? On digital, if the checksum for a received picture element doesn't match, the TV throws it away, so two signals won't superimpose.
Please. If you don't know the technical details, ask, or don't post.
