Okay, I dont know much about cable or satellite technology at all but I think my questions are pretty simple... Is there any type of signal, or transition sent through the cable lines/satellite when the show you are watching stops for an advertisement break? In other words, would there be a way for software to "sense" that ads have come on, and as soon as they are done, when the program is back on, for it to recognize this? My question is regarding regular cable, and also satellite. I want to be able to filter out ads WITHOUT missing a beat! Is this possible? Or is there NO way for software to "sense" the difference between say, a football game and a car commercial? Thanks!
