AJVickery: Well, many of you this is a familiar site sitting with an instruction manual and what you want to do is basically hook up, your entertainment system may be you have got a brand new TV or you've got a brand new speaker system and you need to hook up these things together. There is so many different choices when it comes with the cables that connect the deceive like receiver or a DVD player or even your HD set top box to your television to ensure you'll get the best quality picture. In fact, I had so many people call me after they bought their new TV and they hook it up to the cable outlet in their wall and they have complained about the picture. It was almost worst then what the TV did before.
First of all, let's look at these RCA cables, this is kind of I would say one of the most basic ways that we've connect video and audio from a DVD player to a TV. The yellow represents the video, and the red and the white represent the left and right sound. This solution is an analog solution and it really doesn't pass a high quality signal. So you really not taking advantage of the picture that you could get or the sound that you could get by investing in these higher quality items.
The next one I would give you a little bit better video signal. Video only as if you went from the RCA cable to an S-video cable. And so what's happening with this cable here is that as using these little pins inside you can see there to set in a different sort of pieces of data, the different colors if you will still an analog system, but a higher quality a signal more data that can be sent through the one cable. If you sort of take a step up from there, the component cable what it does, this is after regardless on sort of one of the best ways before we got digital what it does if you take the yellow one away it's taking the red, the blue, and the green and it sending all of that data through this cable here and for the most case you are going to start take advantage of that high quality televisions set that you want to get the great picture for.
Well one of the evolutions in sound has been to digital which is where you have gone something like an optical cable. Now the optical cable starts to deal with a digital signal if I just take this rubber and off this ones from mobster this cable start to get expensive and there is different companies that make them, but just in the very tip there -- will be able to really see it, but essentially it's a glass tube. It's a fiber optic that's running through this and what it's doing is taking that audio sound and it's passing digitally to something like receiver from a DVD player again allowing all of the different signals and now you are going to able to get center channel, your right channel and your rear channel as well and just get a full force surround sound.
In the evolution of cables just to talk about sort of were things are going. Right now a lot of folks have heard HDMI and this is were they really combine those worlds back together again, remember here we sort of have video and audio attached just one of set of cables, but we've gone that way with HDMI and now HDMI contains the video and the audio. But it does it digitally and it's going to send it to your device. You can see there, we've got a number of different inputs here. We can put in our single video and our audios; we can go to that component where we are using the red and the blue and the green. We can use the optical that's going into it really where we want to end up as with this HTMI. We want to able to pass the HTMI from our TV to our receiver from our DVD player or HD box in order to get the best quality signal. So hopefully there is a lot more to it, but hopefully there will kind give you an understanding of where we have come from that cables and ultimately where we are trying to get to.
