1. An apparatus for transmitting a bitstream comprising:
a non-transitory storage media that stores image data and two or more sets of metadata for the image data; and
a processor, wherein the processor;
encodes the image data and the two or more sets of metadata; and
transmits a bitstream including the encoded image data and two or more sets of metadata to a decoder;
wherein:
a first set of metadata describes characteristics of a reference display device that is used to produce the image data, the first set of metadata comprising:
a) a white point for the reference display device, and
b) three primaries for the reference display device,
a second set of metadata describes tone-mapping parameters to display the encoded image data on a display; and
a third set of metadata describes ambient light conditions at the reference display that is used to produce the image data.
