Abstract
Several embodiments of scalable image processing systems and methods are disclosed herein whereby color management processing of source image data to be displayed on a target display is changed according to varying levels of metadata.

(canceled)
A method for processing image data for a target display through a set of metadata associated with the image data, said method comprising:
- receiving the image data as a bitstream at a destination device, from a remote source of the image data, the image data comprising video signals and the set of metadata;
- decoding the image data;
- determining, by the destination device, that the set of metadata includes parameters for a remote reference display used to grade the image data;
- and
- parsing, by the destination device, the set of metadata to obtain one or more metadata-levels available for color management of the target display, at least one of the one or more metadata-levels providing a first set of parameters for the remote reference display, and a second set of source content gamut parameters for the image data,
- wherein the parameters of the remote reference display in the set of metadata includes at least:
- a. a white point, represented as x, y chromaticity coordinates for the reference display,
- b. three primaries, each represented as x, y chromaticity coordinates for the reference display,
- c. a minimum luminance level for the reference display, and
- d. a maximum luminance level for the reference display.
