1. A method for processing a bitstream through metadata associated with the bitstream, said method comprising:
receiving, from a remote source, image data as the bitstream at a destination device, the image data comprising video signals and the metadata;
decoding the bitstream;
determining, by the destination device, that the metadata includes a first set of metadata associated with a portion of the image data, the first set of metadata including one or more parameters representing characteristics of a remote reference display device that is used, during creation of the image data, to color grade the video signals,
wherein the first set of metadata includes:
a. a white point for the reference display,
b. three primaries for the reference display, and
c. at least one luminance level for the reference display;
determining, by the destination device and independently from determining that the metadata includes the first set of metadata, whether the metadata includes a second set of metadata associated with the same portion of the image data, wherein the second set of metadata includes at least a luminance level; and
rendering the video signals at the destination device based on at least one of the first set of metadata and the second set of metadata.
