SDTV component inputs?

[N2x]

I was behind someone's TV today (I'll say for street cred that I was making out with a pretty lady), and I saw component video inputs. But the television itself was 480i. Shouldn't that mean it can't accept component signals? If I plug in something using those inputs, say a Gamecube or DVD player, will the picture quality improve? Will the TV suddenly become 480p?

If it helps, the set is a Sylvannia, or one of those discount brands. I looked at the box it came in and it specified it was 480i.

Component, DVI, HDMI, etc. can go down to 480i.

Will any of those net a better picture than plain old composite?

I don't see why they shouldn't. Composite/S-Video can go to 480i max, but they have much less bandwidth than someting like DVI or HDMI and don't have the luminance and chrominance completely separated.

Look at it this way, imagine your video signals as such:

Red= Red marbles
Blue= Blue marbles
Green= Green marbles
Luminance= Grey marbles

Now mix all of the up in a single tub, this is composite.

Separate Blue, red and green and put them into one tub, put the grey into another tub. This is S-Video

Separate all into separate tubs, this is RGB or component/HDMI.

The less sorting your TV has to do, the better the picture due to less errors. Component is still the best a SDTV will get, even in 480i.

component looks so much better than composite or svideo, even in 480i, especially with ps2. only console that does component that i dont have the cable for is gc since is so stupidly rare/expensive.

component is blue marbles in one tub, red marbles in another tub, and grey in a third. no green.

Actually component is Y/Pb/Pr.

-Y is the luminance information (grey),
-Pb is the difference between blue and luminance (B- Y)
-Pr carries the difference between red and luminance (R- Y).
-Green is what's left.

I just figured a more simple explanation would be better.

thats essentially what i said.

My DVD player has component outs but no progressive scan.

Though I have it connected through component, I notice no difference over S-Video in 480i.

These are number off the top of my head but there is a supposedly a 40% increase in PQ between composite and S-video but that number is halved between S-video and component, some 20%.

I guess that 20% isn't terribly noticeable to the human at a standard TV viewing distance.

It's just my impression based on experience and it's a very good DVD player too.

While we're on the subject, how good of an HD image does SCART present compared to component and VGA?

You're right, it's not a huge amount. I does make a slight difference but not enough to make you feel like it's a stark difference. It also has to do with TV size. I know that on my Hitachi 51", 480i over S-Video from Direct TV can't compare to 480p from my Marantz DVD player...

I thin on you're normal 27"-32", it won't be a night and day difference, even between 480i and 480p.

Good question, I know jack-shit about SCART...

After a little reading it seems that SCART can do Composite, S-Video or VGA. I guess that at full resolution SCART would be better than component (if used as VGA)....

possibly I'm wrong though.

Well, I'd suspect it wouldn't compare since one signal is 480i and the other 480p. But I use a 34" tube and since my DVD player can't output 480p, if there is a difference between the component to the s-video, i can't see it.

By contrast, yes, the connection difference on my XBOX is very noticeable since the XBOX displays games in 480p with component and S-video is incapable of that.
