Cable TV, is info for all channels delivered to TV through coax at once?or does TV send signal to company...?

Question

requesting a given channel? I think it is the former, otherwise splitters would never work, right? Thanks a lot for helping me understand.

Answer 1

ALL ARE SENT AT ONCE ON DIFFERENT FREQUENCIES AND YOUR TUNER PICKS OUT THE ONE YOU SWITCH TO . IF YOUR TV HAD TO ASK FOR A CHANNEL ------YOU COULD NEVER HAVE MORE THAN 1 TV STATION PLAYING ON ALL YOUR TVS. IN YOUR HOUSE AT ANY ONE TIME .
