DCI Releases High Dynamic Range D-Cinema Addendum, Version 1.0, and
Direct View Display D-Cinema Addendum, Version 1.0
Approved for Distribution 30 March 2022

Advances in High Dynamic Range (HDR) technology in both reflective projectors and direct view displays offer new opportunities to enhance the theatrical motion picture experience. The proper presentation of a High Dynamic Range Digital Cinema Distribution Master (HDR-DCDM) requires the definition of an HDR Reference Display and controlled environment. The High Dynamic Range D-Cinema Addendum, Version 1.0 defines the HDR Reference Display and specifies the tolerances around the critical image parameters for Review Rooms and Exhibition Theaters so that consistent and repeatable image quality can be achieved.

D-Cinema Direct View Displays have now entered the marketplace, representing a new technology that was not available when DCI's Digital Cinema System Specification (DCSS) was initially created. New requirements are needed to ensure that the security and quality of these devices meet DCI specifications. The Direct View Display D-Cinema Addendum, Version 1.0 defines performance requirements for D-Cinema Direct View Displays, which are intended to ensure interoperability and consistent image quality on these types of displays.

See the current DCI Specification page of the DCI web site for further information.

DCI Releases Memorandum on HDR Double-Blind Image Testing
Approved 1 July 2021
Digital Cinema Initiatives, LLC, Member Representative Committee

 

For the past several years, Digital Cinema Initiatives, LLC (DCI) has been working to determine appropriate criteria for next-generation projection and display specifications, particularly to enable High Dynamic Range (HDR) in the theatrical environment. DCI's efforts were undertaken in response to technological advancements in HDR, filmmaker desires for additional storytelling capabilities, manufacturer requests for guidance, and a desire to further enhance the movie-going experience.

As part of the specification development process, DCI performed a number of double-blind image testing studies to determine the perceptibility of certain technical parameters, particularly black levels and peak brightness.

The purpose of this memorandum is to provide a summary of the process and findings from these testing efforts, how they guided the specification development process, and define peak brightness and black level values for next-generation projectors and displays based on the results.
