Abstract
A method is provided for encoding a digital video to improve perceptual quality. The method includes receiving a digital video at a video encoder, providing a perceptual quantizer function defined by wherein L is a luminance value, c, c, c, and mare parameters with fixed values, and mis a parameter with a variable value, adapting the perceptual quantizer function by adjusting the value of the mparameter based on different luminance value ranges found within a coding level of the digital video, encoding the digital video into a bitstream using, in part, the perceptual quantizer function, transmitting the bitstream to a decoder, and transmitting the value of the mparameter to the decoder for each luminance value range in the coding level.
