DCI previously released draft versions 0.9 of these Addenda on 16 November 2018. Having considered industry comments on versions 0.9 and after additional testing, DCI now releases draft versions 0.96 of the High Dynamic Range and Direct View Display D-Cinema Addenda for consideration by interested parties.

These documents are not DCI Specifications. These Draft Version 0.96 documents are distributed for review and comment prior to publication of final DCI specification documents. Please submit comments to DCI by 1 October 2021 via email to image is not clickable to prevent spam.

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. This DRAFT specification 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 color quality can be achieved.

D-Cinema Direct View Displays provide the potential for an improved high-quality image through significantly increased peak luminance and dynamic range, but may also be used to present legacy content. This DRAFT specification defines performance requirements for such displays that are unique to D-Cinema Direct View Displays. These requirements will ensure interoperability and consistent quality of image content on the new generation of d cinema displays.

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