In short, S-Video is a "step up" from Composite Video. So, S-Video is better, if you can tell the difference on the device in question.
Long answer:
My wording of "step up" is not entirely accurate - in video image processing, within a device the image is stored and processed at the highest quality possible (most of the time), and then only downgraded to the type of connection required. The following is the breakdown of the three most common connection types for analog video.
Video information usually consists of luminance (brightness) information, and chroma (color) information. This may or may not be explicitly synchronized by provided synchronization lines (as it is with a PC monitor). The most common standard used today is the so-called RGB - that's Red, Green and Blue (the three colors from the additive palette that can make up any other color when mixed).
When you combine that RGB information into Chroma and separate Luminance (brightness) from it, you get S-Video (4 pins, 2 wire pairs, one for Chroma and one for Luma). Of course some information is lost due to this combining, and quality suffers.
In order to get that information to "fit" into just one pair of wires (e.g. an RCA-RCA cable) it must be "mixed" in a way (not dissimilar to air TV broadcasting), as to have them 'pass through each other' without losing them. Once again - quality suffers from this, as the signals influence each other. This is Composite video.

∙ 14y agoWithout a doubt, component video is the better quality compared to S-video. While both carry idenitcal luma sgnals (the black and white brightness signal), the color information is carried on a restricted bandwidth on an S-video cable. Component uses two separate color information cables and can carry full bandwidth color information as a result.
Havong said that, S-video will often appear virtually as good as component signals. The full quality luma signals in S-video fool the eye into thinking that the color information is just as sharp. Althgou component is definitely the better interface to use, don't be in too much of hurry to invest large amounts of time or money into upgrading unless you can truly see the difference.

If you have a 3 wire RCA cable with an s-video cable do you have to use the s-video cable?
No, you can use the VIDEO cable instead and just let the S-CABLE hang loose but the S-Connector/Cable will give a better picture so use it if you can.
Can you play a VHS through a projector if so what cable do you suggest?
Audio and Video cables, red and white for audio and yellow for video, if both units have a S-connector use it. The S-cable is a better video cable. If you use a S-cable you don't use the yellow video cable.
What is s-video input on an lcd tv?
The S-Video connector and cable will give you a better picture than coax or a RCA type pin video connector and cable will.
Do you need an audio cable with a s video cable?
Yep. S video is video only
What is s-vidio?
S-VIDEO is a better way to connect equipment together which will render a better picture than the common yellow video connection. Use the S-Cable if the equipment has the S-Jack.
Which television input has the best picture DVI S-video component HDMI cable?
HDMI is by far the best. and S-Video is better than the VIDEO connection.
Which connector would you use to connect an S-video cable to a portable computer?
No portable computer has had a S-Video output in the last 5 years. You might find a S-Video input on an older TV. You can use a S-Video cable to connect the computer to the TV, although a VGA cable would look much better if the TV had that option.
What resolution can you get through an S-Video cable?
An S-video cable carries standard definition video, and with it you can get a resolution of 576i.
Can you splice a s-video cable to an HDMI cable?
no s-video is a radio frequency hdmi is digital
How do you get the Sanyo pro xtrax projector to work with your laptop?
you can put a video-cable in the video port from your laptop with an adapter cable witch end in a tulip cable(yellow). the (yellow) tulip cable is conected in the S-video in port section below the S-cable input. if you can vind the adaptor witch end in a S-cable it,s better bud harder to vind. the usb connection does not work without the driver,do not know were to find one.
Will s-video cable deliver audio?
No, the s-video is a video only connection.
How does an HDMI cable function?
The HDMI cable works but transmitting audio and video by using digital codes of 0's and 1's. This cable gives the data better quality and it is very simple to use.
