kaj pomenijo oznake Y/Pb/Pr

Oznake za signal: uporablja se pri analogni povezavi/kompozitni kabel (Y/Pb/Pr), S-video je pa S-VHS.

Definition of: YPbPr

The designation for analog component video signals. The "Y," "Pb" and "Pr" are sets of three inputs or outputs on better video equipment and TVs. The three cables used in a YPbPr connection represent higher quality than the single-wire composite cable commonly used to hook up video equipment, because the brightness and color components of the signal are maintained separately. The YPbPr signals are derived from the red, green and blue (RGB) colors captured by a scanner or digital camera, and RGB is converted into brightness and two color difference signals (B-Y and R-Y) for TV/video. See component video.

YPbPr and YCbCr
YPbPr component video is the analog counterpart of digital component video, which is YCbCr. Whereas YPbPr uses three cables between video equipment, YCbCr uses a single cable. See Y (B-Y) (R-Y), YCbCr, YUV, YUV/RGB conversion formulas and color space.

razlog za tole kompliciranje z matriciranjem signalov je v bistvu kompatibilnost barvne televizije s crno-belo... ta "vidi" in potrebuje samo Y signal

podobno je pri radijskem stereo zvoku, kjer imas L+R in L-R... mono radijski sprejemnik rabi samo L+R
