Pr label is for component video
R label is for the red channel for RGBHV video

Green Connector:  Y/G

Y label is for component video
G label is for the green channel for RGBHV video

Blue Connector:  Pb/B

Pb label is for component video
B label is for the blue channel for RGBHV video

White Connector:  L/H

L label is for the left analog stereo audio channel
H label is for the horizontal sync for RGBHV video
