wHat is s video?

Question

what is an s video out put and imput and wats the purpose of s video oppose 2 HD MI and red white and yellow wires?

Answer 1

S-Video is better than composite (yellow). composite has 2 wires inside the cable, so all video information is contained in them. S-Video uses ,i think 4,might be 5, wires and the picture quality is usally a bit better, not always noticble.
S-Video and Composite(Yellow) are both analog and max out at 480p
you didn't ask about this but Component (Green, Red and Blue) are even better than the latter two. they're usually used for HD signals and support 1080p.

HDMI is the best to date, the signal is completly digital and very little information(color information) is lost, it also supports very high resolutions.

as far as i know in most cases the HDMI can carry the audio signal AND the video signal
other cases where a DVI input or output is converted to HDMI with an adapter, the audio signal cannot be carried, in which case you'd need the red and white... or SPDIF(coaxial or optical)

in the case of BluRay if setup(from tv to player and whatever's in between) that isn't 100% HDMI, the bluRay player will downscale the video to 480p.

how that helps =)

Answer 2

When color television was developed, the color information was included on a separate signal mixed in with the black and white information. This made the system compatible with existing TVs: they just ignored the color part, the black and white part was just like ordinary television. The combination of the color and black and white signals into one signal is called a "composite" signal and is what you get from the yellow plug in your TV.

The two signals do not blend perfectly and there is some interference which affects the quality of the video. So when JVC introduced their "Super-VHS" video tape system, they decided to keep the color and black and white signals separate for recording and maintained that separation all the way to a special output called "s-video", which could mean "super vhs video" but really means "separate signal" video. The connection has four wires, two for the black and white and two for the color. The use of s-video results in better color defintion (less color "bleeding") in the picture. And interference patterns (dot crawl at image edges) is reduced.
