Comment (by Balling):
>Actually the existence of the limited-range thing much derives from the
analog legacy
No, it really does not, reference black was for example 7.5 IRE, 53.57 mV,
{{{

}}}
YUV was using different matrix and some analog TV was not even using any
matrix, it was linear RGB (only SECAM IV used linear RGB) or non-linear
R'G'B'. Besides, 16-235 was not even a thing intially. They were planning
to set black and white level at different values.
