High dynamic range enhancement authorization

Abstract:

Systems and methods for selectively enabling enhanced high dynamic range (HDR) metadata for enhanced HDR playback of media content stored on a media disc are provided. Media discs may be authored with a base layer media content in accordance with a non-enhanced HDR media profile. Media discs may also include enhanced HDR metadata. In order to enable the use of the enhanced HDR metadata, a media player in which the media disc is inserted for playback may first seek authorization from a third-party resource, such as an authorization server. Only after obtaining authorization is the media player allowed to playback the media content stored on the media disc in conjunction with the enhanced HDR metadata. If authorization is not obtained, the media player may only play the base layer media content.
