    摘要: A secure digital data distribution system (100) for preventing unauthorized access to digital data. The system utilizes an identification system module (116) embedded in a digital storage media (114) to grant authorization to media players (118). Prior to reading the digital data recorded on the media (114), an identification system interrogator (122) reads authorization data from the identification system module (116) to determine whether the media player (118) is authorized to read the media (114). If the authorization data matches the media player's unique identifier, authorization is granted and the media player (118) commences to read the media (114).

    摘要: 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.
