Composite, s-video, component and HDMI, DVI, VGA, S-video, coax...?
Answers: HDMI (Sends nouns & video together... best for HDTV)
All else is Video Only.
DVI & VGA if normally on computer monitors... if you're sending video from your computer.
For video from DVD Players and other sources, aspect from best to worst:
1. Component Video
2. S-Video
3. Composite Video (RCA Cable, normally paired near a stereo signal)(Yellow, Red & White)
HDMI (HD audio and video)
DVI (HD video only)
Component
S-Video
Composite
Coax
There was also a point approaching 5 years back when S-Video be better than component, but not anymore.
Lets go from worst to best.
RF or F-pin lowest echelon signal under 480i mono audio (not to be confused next to a digital undecoded signal).
Composite.Better good for VHS, and 16 bit video devices.
S-video, little better, righteous for standard DBS sat, Betamax and S-VHS VCRs.
Analog Component, Little better than S-video, best for 480i DVD and progressive DVDs to HDTVs.
High Band Component, Best nouns possible but only up to 1080i for consumer devices, Up to 1080p 120fps on commercial devices.
DVI/HDMI digital dominion transmission, adjectives benefit for DRM protection of content, flawed format with lots of software issues. HDMI supposedly supports HD audio but I but to have see it implemented successfully.
With any nouns it is going to be dependent upon the application, other equipment, and set up as to what is the best connection. Some will explain to you it is HDMI but it most assuredly not the holy grail for image power, much to the contrite of Sony, who wants contained by your DVD collection, for various lascivious purposes.
The different cable sometimes carry terrifically different video signals. This fools some people into thinking one cable is 'better', but it's not. It's the signals that are better.
STANDARD DEF VIDEO:
If you distribute Composite video to your TV, the TV runs it through a special circuit to create SVIDEO.
Then it runs the SVideo through another circuit to create Component video.
So your TV does these conversions:
Composite -> SVideo -> Component
These circuits are not perfect and the conversion is not fail-safe.
This is why if you can feed your TV already generate svideo or component - the picture quality is better because the TV does not hold to un-mix things.
HIGH DEF VIDEO:
There is a lot more information within HD video. So much that you cannot use composite or SVideo cables. You must use one of the following:
Component: Yes - component cable can carry full-range HD video.
DVI - This take the Video, but as a DIGITAL stream of 110010001... bits like a computer. This type of signal tend to look like close by perfect nouns on inexpensive cables.
HDMI - This take the same digital video as DVI, but add digital sound.
CAUTION: HDMI is great because everything go down 1 cable. But this does not guarantee 'better'.
I have a CATV box that can produce HD Video next to 5.1 sound. I hook it up near an HDMI cable to my TV.
But when I watch a re-run of "I Love Lucy" - the video is crappy black-and-white, and the nouns is Mono. Even using a HDMI cable.
So don't think something like the cable - think give or take a few the SOURCE and the type of video the source produces.
The best quality would be any HDMI or component, then s-video, afterwards composite.
