Subjectso is component better than an rgb scart? Reply to this message

I just bought a new LCD TV set (Samsung LE40S86BD if you're interested - I know the R series performs better, but this was less expensive).

I wonder how am I supposed to connect stuff to it. Analogically, since I have nothing supporting HDMI or DVI (yet?).

I have an understading that RGB scart > S-Video > Composite, since the information travelling on different channels is more clean and so on.

However, I am in doubt about component vs rgb. In both cases there are three channels carrying the same information, only distributed differently (rgb are primary colours, component is luminance + red difference + blue difference (green can be obtained by summation)).

So I was wondering, what is better? And why. I have a basic knowledge of signal theory and communications, so a tech explanation would be welcome.

Also: I have the regular cable and an s-video cable for my XBox (not 360), should I upgrade to RGB scart? Do xbox->component/hdmi cable exist anywhere, that I can order, if it's worth?

Sorry if the questions sound stupid :P

But component is truer to the way images are generated from DVD sources (ie. from compression). RGB is basically loss less, but if you're using a lossy source then it doesn't really matter. Component Y'PrPb also uses less bandwidth by dividing up the image across three lines rather than using 3 lines with the same image but from different primary colors.

So it basically comes down to what you want to do. Either way, both are analog. Not a very good/clear answer, but in my opinion, if you're watching a movie, you're probably not going to notice the difference.

I've been reading something, and it looks like, while RGB is theoretically better, as you say, in practice the SCART connector sucks big time. On the TV I have the standard RCA inputs for Y'PrPb, but I can't find a cable for the old XBox, while the rgb scart is easily found... I guess the console natively outputs RGB, and not component, so I guess I'm stuck on that.

Meanwhile I'm using S-Video, which is surely a lot better than composite (less ghosting), but still a bit blurred for gaming.

On the XBox, I can only use what is there. I am so out of the loop that I checked the Lik Sang website, only to find Sony had it closed so long ago... Give a bro' some gaming love, guys!

I'm gonna get me a HDMI capable DVD player some day, but for now the XBox will have to suffice.

3rd party like from madcatz or something, I don't remember. You could find those pretty easily over here back then.

Hell I even built one myself. Actually it was a vga cable that I built but with a quick mod it became an vga/component cable. Check xbox-scene for tutorials and diagrams.
