Abstract
A transport stream with embedded projector configuration data 208 being carried along with the video for use in digital cinema projector setup. The embedded configuration data consists of sub-packets 304 of setup data information for such parameters as gamma tables, color management system information, relative luminance level, format and range of the sampled data, 3D/2D presentation information, frame rate, image size, aspect ratio, font tables, and language provision. This approach assures that the projector 404 is setup properly and also permits on-the-fly changes to the projector's parameters, which may be used for artistic effects in the movie.
