DCI Memorandum Regarding Direct View Displays
Approved 27 June 2018
Digital Cinema Initiatives, LLC, Member Representatives Committee

 

Direct view displays provide the potential for an improved high-quality image through significantly increased peak luminance and dynamic range.

The current Digital Cinema System Specification (DCSS) and Compliance Test Plan (CTP) were crafted with projection systems in mind. With the advent of direct view displays, the associated system architecture and performance characteristics differ from projection systems such that new specifications are necessary. This document broadly defines performance and security parameters that DCI intends to define for these types of displays in order to give manufacturers guidance while a complete set of requirements is developed. Parameters defined in this memo are tentative and subject to change.

DCI Image Evaluation Summary
Approved 11 May 2018
Digital Cinema Initiatives, LLC, Member Representatives Committee

 

During December 2017, DCI conducted viewing sessions utilizing short clips (approximately 15 to 25 seconds) of existing theatrical content that were chosen based on their suitability for image comparison testing in a higher dynamic range projection environment

DCI Memorandum on RNG Revocation and Related NIST and FIPS Developments
Approved 16 March 2017 and 11 May 2018
Digital Cinema Initiatives, LLC, Member Representatives Committee

 

On March 23, 2018, DCI posted revisions to the Compliance Test Plan (CTP) that include new "secure silicon" requirements. Following the "stage 2" 120 day window, these requirements will be enforced as of July 21, 2018. In order to further smooth the transition, DCI is extending the below exclusion and grandfathering clauses to include all secure processing block (SPB) devices, which the Digital Cinema System Specification now requires to employ secure silicon.

Memorandum of Information Regarding the Secure Silicon Requirement of the DCI Digital Cinema System Specification (DCSS)

Approved 10 May 2018
Digital Cinema Initiatives, LLC, Member Representatives Committee

 

In conjunction with publishing the DCI Compliance Test Plan (CTP) test for Media Block (MB) secure silicon requirements, DCI anticipates there may be questions or concerns as to where to source such single chip integrated circuits (IC). This memo is a guide to NIST site information that lists qualified ICs, and other methods to meet DCSS and CTP secure silicon requirements.

DCI-MMB Architecture Description
Approved 26 June 2014

The existing DCI Digital Cinema System Specification (DCSS) security architecture is based on a single Image Media Block (IMB) per projector per auditorium. This is an introduction to an alternative to the current model referred to as the Multiple Media Block (MMB) architecture.

MMB operation enables multiple Media Blocks (MB), each containing a Security Manager (SM), to be used in DCSS compliant projection booths. A new MB type - the Outboard MB (OMB) - is defined for use in MMB configurations.

Response To Industry Inquiries
Regarding
The Digital Cinema Object-Based Audio Addendum
Approved 23 April 2014

The Digital Cinema System Specification (DCSS) defines a projection booth architectural model centered on a single Security Manager (SM) contained within a single Media Block (MB) specified as the Image Media Block (IMB).

DCI recently issued the Digital Cinema Object-Based Audio Addendum, providing basic requirements for how this new essence type can be accommodated within DCI compliant architectures.

This document is a response to industry inquiries regarding the OBAE Addendum and the need to enable efficient implementations while preserving the fundamental architectural tenants important to maintaining security.
