Hi def sounds good to me.
EDIT: After searching...
It's for component analog video YPbPr. The green is the Y, the blue is the Pb, and the red is Pr.
The red,white, yellow is composite analog video and analog audio, the yellow being video, white left audio and red right audio.
Best I can interpret the cables are interchangeable so if you plugged the red white yellow into the green blue red it would work.
