GSCA Releases Digital Immersive Giant Screen Specifications (DIGSS) Version 2.0
GSCA is pleased to announce the release of the Digital Immersive Giant Screen Specifications (DIGSS) version 2.0.
DIGSS is an initiative to establish technical specifications for
digital theaters with giant flat and dome screens. It shares many of the
goals of the Digital Cinema Initiatives (DCI) specification (which
standardized digital projection for multiplex movie theaters), and
presents specifications for the unique requirements of ultra-high
resolution digital giant screens that were not part of the DCI
specification. DIGSS-compliant theaters may be fully DCI compliant,
partially DCI compliant, or non-DCI compliant.
the technical specifications for immersive cinema films and theaters
with the goal of maintaining and expanding a global network that is
clearly differentiated from conventional movie theaters, and large
enough to support a robust market of films designed specifically for
DIGSS 2.0 is the third formal revision of the
DIGSS 1.0 document that was the result of the Digital Immersive Screen
Colloquium for Unified Standards and Specifications (DISCUSS).
latest version significantly simplifies the structures of the narrative
section and the table of specifications compared to earlier versions.
The intent is to make it easier for users to locate the information they
need to ensure that any digital projection system they are considering
as a replacement for their film system (or an early digital system) will
provide the highest standards of image and sound quality.
2.0 also recognizes two new technologies that have dramatically
enhanced digital image quality: high frame rate (HFR), which increases
the number of discrete images captured and presented beyond the standard
24 frames per second that has been the standard in cinema for nearly a
century; and high dynamic range (HDR), which expands the range between
the darkest blacks and the brightest whites that a projection system is
capable of presenting.
We would like to thank the GSCA
Technical Committee, committee chairs Tim Hazlehurst (Marbles Kids
Museum) and Michael Daut (Evans & Sutherland), and committee
members James Hyder (LF Examiner), Alvis Wales, and Gord Harris (Christie) for their help in writing DIGSS version 2.0.
