The Difference Between HDTV Analog Cables

Video Transcript

Hi, I'm Brad Bear on behalf of Expert Village. In this clip I want to talk about the different kinds of cables that you're going to have to look at when dealing with High Definition players and High Definition Televisions. Now the first kind of cable you're going to run across is pretty standard. You're probably used to it, this is the coax cable. the coax cable is just the threaded end on a single cable, and that's where all the video and audio comes from. And it's probably what you're used to if you have cable in your house. Just plug the coax cable into that little screw knob on the back of your set and you're ready to go. Problem is, everything comes through there. So it's not necessarily the best image unless you have a digital signal coming through from the cable company. The other option you have is composite. Now composite again, is kind of sending all the luminance and chrominance values, that's light and dark and color squeezed in the one cable and coming through. You know these as RCA cables. The red, white and yellow cables that you're probably used to seeing as well with DVD players and things like that. The yellow cable is generally used for video. The red and the white's used for audio. But the big secret is, they're just cables and wire, and you can kind of switch them up if you'd like to. The next option you have is S-Video. S-Video is also called YC, is a type of cable that splits up the color information and the luminance information, that's light and dark, into two different cables that come into your set. And so you can get better definition of color, and the light to dark, the luminance information into your screen. And it gives you a much clearer image. And then third is the kind of grand daddy of analog cables anyway, and that's component. Component is the red, green and blue cables that you might be used to. Kind of looks like the RCA cable, which is the type of connector on the end of it. But component takes the red, green and blue color information, which is what video uses, red, green and blue light to make an image, separates them and gives them to the TV. independently. So it can give you the absolute best reproduction of color and light and dark in the image. Of course each color has a different value of light and dark that comes through. But it's all separated and put back together and it looks great. The problem is S-Video and component, neither one carry audio, so you're going to have to use RCA cables, the red and whites to carry your stereo audio. Or something like a digital audio signal through a receiver or something like that.
