19. The method of claim 1, wherein at least one of the one or more adjustments specifies scene-by-scene adjustments.

20. The method of claim 1, wherein at least one of the one or more adjustments specifies frame-by-frame adjustments.

21. The method of claim 1, wherein at least one of the one or more adjustments specifies an adjustment to a sub-region of at least one frame.

22. A method of preparing a tailored video for presentment with a desired display device;

the method including the steps of;

providing a video; and

providing a display information hierarchy for a plurality of display devices, for each display device the display information hierarchy including information related to one or more adjustments to the video prior to presentment with the respective display device.
