Status Report: D-Cinema Technology Committee

(DC 28)SMPTE Conference

Los AngelesOctober 19, 2000

Why Standards?

• Need to Ensure– Interoperability– Compatibility– Performance– Extensibility

• Desired by Many, Demanded by – Content Owners– Exhibitors

Why SMPTE?

• Neutral Cross-Industry Technical Forum

• Established Track Record

• SMPTE provides a host function, to help the industry figure out D-Cinema

• The SMPTE end product will be standards, but the early assessment phase is broader

DC 28 Technology Committee

• Due Process Committee– Can Write Standards, But Has Not Yet Done So– Has Fairly Strict Guidelines & Procedures

• Management– Curt Behlmer - Chair– Bob Rast – Vice Chair– Mark Hyman – Secretary

Committee Scope

• DC 28 includes– Mastering– Distribution (transport)– Exhibition

• DC 28 does not include– Capture – Production

DC 28 Mission Statement• Provide Industry Technical Forum for D-Cinema

• Identify Key Systems & Technology Issues

• Develop a Recommended Approach to Standards

• Identify, Establish and Coordinate Necessary Groups to Achieve Overall Objectives

• (Future) Write the SMPTE Standards

Study Groups

• Considering that– SMPTE is a host for the industry– The initial need is broader than just SMPTE

standards

• We created study groups initially– Not due process working groups– Broader charter, but don’t write standards– Can evolve to working groups, write standards
