Hi,
Can I use Composite cable for Component video?


Please correct me if I am wrong. If I connect the same color code cables on the Y, Pr and Pb ends of the DVD player and the TV, will the composite cable works as component cable?

Please help

If you are referring to the red/white/yellow cables, that would be a bad idea. Most audio cables in that scenario are not coax.

It won't pass an HD signal. Don't do it. It might work for a progressive scan DVD player output but that is it.

You should get a picture and it won't hurt anything.
But, a composite cable may not be made of 3 identical pieces of co-ax cable.
For best picture results, I would upgrade to a real component cable.

.... or you can use three "yellow" composite cables connected to matching colors (red/green/blue) at each end.

"Identical" means that should all be: the same length, 75 Ohm coax (RG-6, RG-59), with RCA connectors. Easy to build if you have spare coax and connectors. If you want to buy, check out http://www.monprice.com

As I said, it "works" but it doesn't work..... why not buy the correct cable for very little money at www.monoprice.com? The cables are not the place to skip on.

Yes it does work and pass HD, period. We have installed many plasmas were the customer had dishHD installed without having the tv intially and the installer just left it hooked up to their old tv with composite.

We try to sell the customer some inexpensive component or hdmi cables but most of the times they are very cheap and bearly want to pay for the install.

So we just give them an extra set of RCA (red,white,yellow) and run it as component and yes it does pass HD. At least with 6' cables.

But if you have 3 sets I would only use the yellow, just make sure to mark which cable is red, green, blue.

Works. I used RG-59 coax and built the cables myself simply because I had the time, parts, and it was fun to do.

I would emphasis hdtvpros point about using only the yellow. The red/white (audio) part of these cables have next to no shielding, the yellow part has at least some shielding. While it's not RF, you still need a minimal amount of bandwidth to carry the signal. Good shielding goes a long way here.

Come off it- use the right stufff.

What is the right stuff? If your that picky paint all three yellows to red, green and blue. When they manufacturer cheap component cables they use the yellow(composite) cables just use different color boots.

Tells us what brand is the right stuff and I will take three yellows and compare.

I personally like to get three pairs of 14g speaker wire and solder rca connectors and use wala component cables.lol j/k :D

I use some RCA brand RCA cables that I bought from Home Depot. The insulation is clear so you can clearly see the copper braid and that it's a coax cable.

So what is the difference between these cables and ones that say "Component" and cost twice as much?

Quite a few ppl recommend using only the yellow cable of an A/V cable. I really doubt it is necessary if you have a stereo A/V cable. The connectors are all identical except for the color. The cables all have the same thickness. How likely is it that the manufacturer would bother to use a different cable for the Video?

If you use the yellow (video) cable of 3 separate cable, it would do more harm than good. I don't think a typical person would have 3 sets of completely identical A/V cable. Chances are they are not only different in quality but different in length as well.

Can you use 75 Ohm coax cable, for video signals, with 75 Ohm source and load terminations?

Yes.

What's the difference between a coax cable, sold for composite video and one sold for component video?

Nothing.

Do you understand about component cables and the connectors used on the ends? They are soldered on? I need help before I start putting connectors on these wires.

I PMed you about what we were talking about.

To terminate a coax cable with an RCA type jack requires a crimper or compression tool, this will be pretty expensive. You can buy a great compression tool that does only F-Connectors (normal cable television connectors) for a great price. From there, they make little fittings that adapt from the F-Connector to RCA. That method seems to be well liked in this forum for people are aren't going to do it often enough to invest in the tool.
