hehey guys, im sorry if this is the totally wrong place. if it is, mods please move it.

component video (Y Pb Pr). what are the three channels, and what do they do? i have to do a short lesson tomorrow for one of my classes, and this is the one thing im not sure on. every definition i get says "lumance" and crap, but i need a simple explanation, sine i will be "teaching" a class full of people who don't knwo anything about HD, or video cables/resolutions.

i appreciate the help guys :)

Greetings

B/W info ... (Y) and red and blue information on the other two channels.

Green is derived mathematically rather than actually provided.

Saves space ...

If:

R=4
B=2

Answer is 10 ...

R+B+G=10

You can now figure out what green is.

Perhaps a simple explanation would be:

Composite video is the lowest fidelity method of carrying a color video signal. It only uses one coaxial cable and the luminance (B&W) is combined with the color information over one cable.

S-Video is the next best method. It uses 2 coaxial cables. Luminance is carried over one and color is carried over the other. There is less cross-contamination between the B&W and color info in the picture.

Component video is the best of the 3 methods mentioned thus far. It uses 3 coaxial cables, 1 to convey the luminance channel, and 2 separate "color difference" channels. The result is greater color bandwidth and purity.

michael TLV - thanks for that, helped me out at on

georgeAB - appreciate it, but composite and S video i already know about.

I would suggest reading the articles on Poyton's website. www.poynton.com

thanks for the info guys :) im all set now, adn ready for my lesson tonight!
