只有这些了，十分抱歉：

SMPTE-240M Y'PbPrThis one of the developments of NTSC component coding, in which the B primary and white point were changed. The CRT gamma law is assumed to be 2.2. The white point is D65, chromaticity coordinates are:     R:      xr=0.67     yr=0.33    G:      xg=0.21     yg=0.71    B:      xb=0.15     yb=0.06    White:  xn=0.312713 yn=0.329016The conversion equations for linear signals are:
    X = 0.567*R + 0.190*G + 0.193*B    Y = 0.279*R + 0.643*G + 0.077*B    Z = 0.000*R + 0.073*G + 1.016*B    R = 2.042*X - 0.565*Y - 0.345*Z    G =-0.894*X + 1.815*Y + 0.032*Z    B = 0.064*X - 0.129*Y + 0.912*ZThe coding equations for non-linear signals are:    Y'= 0.2122*R' + 0.7013*G' + 0.0865*B'   Pb=-0.1162*R' - 0.3838*G' + 0.5000*B'   Pr= 0.5000*R' - 0.4451*G' - 0.0549*B'   R'= Y + 0.0000*Pb + 1.5756*Pr   G'= Y - 0.2253*Pb + 0.5000*Pr   B'= Y + 1.8270*Pb + 0.0000*PrThe conversion equations relating SMPTE 240 RGB to EBU and 709 primaries are:     R240= 0.7466*Re + 0.2534*Ge + 0.0000*Be    G240= 0.0187*Re + 0..9813*Ge + 0.0000*Be        B240= 0.0185*Re + 0.0575*Ge + 0.9240*Be    Re= 1.3481*R240 - 0.3481*G240 + 0.0000*B240    Ge=-0.0257*R240 + 1.0257*G240 + 0.0000*B240    Be=-0.0254*R240 - 0.0568*G240 + 1.0822*B240and:     R240= 0.7151*R709 + 0.2849*G709 + 0.0000*B709    G240= 0.0179*R709 + 0.9821*G709 + 0.0000*B709    B240= 0.0177*R709 + 0.0472*G709 + 0.9350*B709    R709= 1.4086*R240 - 0.4086*G240 + 0.0000*B240    G709=-0.0257*R240 + 1.0457*G240 + 0.0000*B240    B709=-0.0254*R240 - 0.0440*G240 + 1.0695*B240
