A method for transmitting a bitstream, the method comprising:
- accessing with a processor image data and two or more sets of metadata for the image data;
- encoding with the processor the image data and the two or more sets of metadata;
- and
- transmitting 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.
