I recently got digital cable and upon receiving the box I noticed it had a digital audio out, as well as an S-Video out. Now the analogue digital audio out has obvious benefits, as the cable box outputs a signal that is split into 5 channels. However I don't see how the S-Video can give you any benefit when the original source (the cable from the cable company) is a coax cable. Wouldn't a coax-in (into the cable box from the wall) and a coax-out (from the cable box to the TV) be the "cleanest" connection? I would think so, since as with anything, you loose quality the more you "process" the signal. It's kind of like saving a .jpg on your computer. Every time you save that picture, it gets compressed and the picture degrades a bit. However after calling the cable company, one of the tech representatives said that the S-Video will give me a better picture because of the way the signal is processed. But this just doesn't make any sense to me. "You can’t get a better picture than the original source," I thought. Wouldn't that be violating some law of of physics? After doing some unscientific testing, I've found that my untrained eye can't tell the difference between the coax signal and the s-video signal. However in the back of my mind I'd always like to think I'm not "loosing" picture quality by using one over the other. So does anyone know the truth behind these digital cable boxes? Can S-Video give you a better picture even if the original source itself is coax?
