1. A system for encoding and decoding an image signal, comprising:
an encoder, wherein the encoder includes at least one encoder processor, at least one encoder memory, at least one encoder input, and at least one encoder output; and
a decoder, wherein the decoder includes at least one decoder processor, at least one decoder memory, at least one decoder input, and at least one decoder output;
wherein the encoder and the decoder are in communication over a network;
wherein the at least one encoder input is image data related to the image signal;
wherein the encoder is operable to process the at least one encoder input, thereby creating the at least one encoder output;
wherein the at least one encoder output is xyY data, wherein the xyY data corresponds to a set of values in an International Commission on Illumination (CIE) xyY color space, wherein the xyY data includes data related to two colorimetric coordinates (x and y) and a luminance (Y);
wherein the at least one encoder output is transmitted to the decoder, thereby creating the at least one decoder input;
wherein the decoder is operable to process the at least one decoder input, thereby creating the at least one decoder output; and
wherein a ½ gamma function is applied to the luminance related to the at least one encoder output to create a luma.
