SMPTE RP 2077:2013

This Recommended Practice defines mappings of full-range digital images to and from (i) digital image formats and interfaces that rely upon protected values, e.g. for synchronization, and (ii) narrow-range digital image formats and interfaces where the full-range of code values is not utilized for the range between reference black and white. These mappings are not generally applicable to mapping of source narrow-range images, e.g. studio range images, to full-range images.
