S-video or RCA?

Which provides better quality? I assumed that S-video was better quality but i've been told that it's just a cheaper solution then RCA. Anyone know the truth? Thanks.

SVideo plugs cost almost 3x RCA... I thought SVideo was the better stuff..

svideo provides better quality. If I remember right, the color/scan signals are seperate all the way thru.

VGA
Component
S-Video
Composite (aka RCA)


That's the pecking order :)

S-Video provides around mid 500 lines while composite video (RCA) is around mid 400.:cool:

S-Video cables themselves DO NOT provide any more lines of resolution than an ordinary composite RCA cable does. S-Video simply separates the chrominance (color) and luminance (brightness) signals, allowing for a sharper picture with brighter colors, less "dot crawl," and other visual artifacts.

Component video takes this a step further by separating the chrominance band into two independent color signals. This gives the ultimate in picture quality, although a true RGB system (i.e. VGA and BNC monitor hookups) is superior.

This may sound dumb, but
Why is VGA better than composite?

I think we're starting to mix A/V and computers now, and I'm not sure that all assumptions hold true for all list items.

But hey, if VGA is "best", you'd better add BNC above that!

Rite, the cable doesn't do jack, its the recording devices that makes it better

Isn't component just 3x RCA? In that case RCA would actually be better than S-Video ;)

RCA is just the plug type...you can use them for lots of things.

BNC and VGA are the best, a true split into RGB (the 3 primary colours of light).
Component is next (which I believe is 3x RCA for the cable), it splits the signal into Y,Cr,Cb which is almost but not quite RGB.
S-Video is next (a little black PS/2 looking plug) splits it into Y and C, which is not as good as 3 parts, but better than one.
Composite is below S-Video (it's 1 RCA usually yellow in colour), it sends the whole video stream in one line.
Coaxial is even lower ;)

correct me if I am wrong..

but RCA is just a connector type, they have RCA audio cables, video cables, etc

RCA itself isn't a type of video cable.. its just the connector end
your looking for the type of cable

Component, composite, etc, etc

Noriaki, you can use three video RCA cables for component connection (3>1, how do you see RCA is better?) in which one carries brightness levels and the other two carry separate color-difference components.

I was making fun of the topic.

S-Video is worse than RCA if the RCAs are used in a Component set up, but S-Video is better than RCA if the RCA is used in a Composite set up.

I was just pointing out the S-Video is a signal format, RCA is just a plug type.

:D Whoops, I missed the joke. I am embarrassed now :eek: My brain was in paper-writing mode (down with school!) and not fun mode.

S-Video is worse than RCA if the RCAs are used in a Component set up, but S-Video is better than RCA if the RCA is used in a Composite set up.

I bet you've confused at least one person with this statement! ;)

what is the 21pin connector?
where does it stand in the list of quality video transmition cables?

colour? isnt it color? hehe

s-video provides better quality then RCA

You can use 3 standard composite video cables for a component video hookup; it actually works! Specialized component video cables are signal-optimized for the most accurate transmission of the Y and Cb/Cr band, but they cost about 3-4x as much (I still don't understand why Monster Cable wants $70 for their &quot;cheap&quot; component video cable...).

I use S-Video throughout on my setup, mainly for simplicity purposes with my A/V receiver. Everything in my setup (including the VCR) outputs an S-Video signal and therefore I don't have to change anything on my TV (very dummy proof for people like my dad). Besides, in all honesty, it's very difficult to distinguish between S-Video and Component video on relatively small screens like 27-32&quot;. It makes the biggest difference where pixel artifacts are more noticeable, like on projection TVs.

Joony: It's also Neighbour, Habour, and lots of other words that are -or in the states are -our in Canada.



<< I bet you've confused at least one person with this statement! >>

Probably that's why I just made a quick little joke about it and moved on.

By the way, because of the way most TVs use the Y and C lines, having a separate Cr and Cb isn't an enormous improvement. You need a pretty fancy TV for Component to be worth the extra price over S-Video. Component *is* better, but they cables are rather pricey. But S-Video is defiantely better than Composite (single RCA).

Erasmus-X, I don't understand how having &quot;optimzied&quot; cables would matter because even the worst coax cable easily has 5-10 times the bandwidth used by even the best S-VHS signals.

Noriaki, I'm no authority on how TVs handle S-VHS Y and C signals, but why would any manufacturer not design a set so that the color and monochrome signals aren't combined until as late as possible, when they reaches the video amplifiers? It seems silly to feeding the Y through the 3.58 MHz color subcarrier filter when the bandwidth can easily be doubled by routing it straight to the video amplifiers.
