Has anyone tried this? Arcadevga and Component?

[picasso]

I was wondering if anyone has tried using an arcade vga card and a vga to component output cable?  Since TV's are almost the same as arcade monitors I was thinking it might work?   Any ideas?

Surely with all the gaming knowledge on this board someone can answer my question.  Maybe it was a stupid question?  I just need to know what to get for my cabinet before it gets here.  I can't afford an arcade monitor but,  I am trying to get close.  I have already been given some advice earlier but am wondering about the arcade vga card as well.

Since the whole point of buying the ArcadeVGA is to get outputs that work great with arcade monitors, using a converter to get component outputs would be a waste of your money.  You can do the same thing with a much cheaper basic VGA card.

OK...  forgive my ignorance but,  I thougt part of the reason for Arcade VGA was to be able to output Arcade VGA resolutions and refresh rates directly to an arcade monitor?  You are saying I can output these same refresh rates and resolutions through a vga card on my pc?  I have read about the ATI hacks but, it still seems that no one has quite got it down to an exact science.  My thoughts were that I could output to a TV the correct refresh and resolution for the games and convert from VGA to component which a TV can recieve.  Please tell me if I am confused.

ok, repeat after me.

Component video is not rgb video.

Most component video systems are variations of the red, green and blue signals that make up a television image. The simplest type, RGB, consists of the three discrete red, green and blue signals sent down three wires. This type is commonly used in Europe through SCART connectors. Outside Europe, it is generally used for computer monitors, but rarely for TV-type applications.

(The above would be for a arcade vga style card)



Another type consists of R-Y, B-Y and Y, delivered the same way. This is the signal type that is usually meant when people talk of component video today. Y is the luminance channel, B-Y (also called U or Cb) is the blue component minus the luminance information, and R-Y (also called V or Cr) is the red component minus the luminance information. Variants of this format include YUV, YCbCr, YPbPr and YIQ.

(This is American style component)


In component systems, the synchronization pulses can either be transmitted in one or usually two separate wires, or embedded in the blanking period of one or all of the components. In computing, the common standard is for two extra wires to carry the horizontal and vertical components, whereas in video applications it is more usual to embed the sync signal in the green or Y component. The former is known as sync-on-green.

Component digital video signals are sometimes referred to as 4:2:2, meaning that for every 4 bits that are dedicated to the Y component, 2 bits each are dedicated to the U & V components on both even (second 2) and odd lines (third 2) of the image. The luminance or Y channel carries most of the image detail and is, therefore, assigned more bits. Another common method, 4:2:0, is used on DVDs. In this case, only the even lines have color information; for the odd lines it is approximated by interpolation. This signal is often converted to 4:2:2 inside the player before it is sent out to other devices.

So if you need to convert to component then use a standard video card like a ati or geforce that support component out directly, much easier than using something that wasn't designed to do it.
