Claim 18:
19. A non-transitory computer readable storage medium storing software instructions, which when executed by one or more processors cause the one or more processors to perform:
using view direction data of a viewer to determine a view direction of the viewer at a time point;
generating an image from a source image in reference to the view direction of the viewer at the time point, the image including (a) a first image portion covering the view direction of the viewer and (b) a second image portion outside the first image portion;
generating an image metadata set for the image, the image metadata set including (c) a first image metadata portion specifically generated for adapting the first image portion to a first display mapped image portion of a first dynamic range and (d) a second image metadata portion specifically generated for adapting the second image portion to a second display mapped image portion of a second dynamic range different from the first dynamic range;
wherein the first image metadata portion is generated based at least in part on a specific brightness level of a display mapped image portion previously viewed by the viewer;
transmitting the image and the second image metadata set to a video client device, the image and the image metadata set to be used by the video client device to generate a display mapped image for rendering to the viewer at the time point.
