A method and system of perceptual quantization for providing a linear perceptual quantizing process of an Electro-Optical Transfer Function (EOTF) for converting received digital code words of a video signal into visible light having a luminosity emitted by a display, including a target contrast dependent exponential video coding providing quantized video levels, with which there is a fixed relative increment of luminosity per quantized video level, so that every quantized video level visibly has the same proportional luminosity variation.
