RGB Gamma CorrectionRGB Gamma Correction
RGB is the starting point for Video and Graphics But RGB Gamma Correction is required because:-
The CRT display is non-linear and computer generated graphics would lack light intensity at low amplitudes
Gamma Correction makes CRT intensity appear linear Gamma corrected RGB (R’G’B’) = RGB where:- Gamma () is 2.2 for NTSC Gamma () is 2.8 for PAL and SECAM
Writing a 1 to bit 0 of the MCTRL register (0xbe50.0034) enables Gamma Correction for the OSD

R’G’B’ to Y Pb Pr MatrixR’G’B’ to Y Pb Pr Matrix
R`G`B` to Y Pb Pr Matrix Y = 0.299R` + 0.587G` + 0.114B` B-Y = - 0.229R` - 0.587G` + (1 - 0.114)B` R-Y = (1- 0.299)R` - 0.587G` - 0.114B`
This gives the following:- Y = 0.299R` + 0.587G` + 0.114B` B-Y = - 0.229R` - 0.587G` + 0.886B` R-Y = 0.701R` - 0.587G` - 0.114B`
But the maximum signal excursion allowable is 1V peak to peak

R`G`B` to Y Pb Pr Matrix (continued.) Y = 1Y Pb = 0.564(B`-Y) Pr = 0.713(R`-Y)
This gives the following:- Y = 0.299R` + 0.587G` + 0.114B` Pb = - 0.169R` - 0.331G` + 0.500B` Pr = 0.500R` - 0.419G` - 0.081B`
Now the maximum signal excursion is 1V peak to peak
