Title: EDCFT
1
EDCF-T
- IBC 2002 Status Report
2
EDCF-CUser Requirements
- Better Quality than Current 35mm Projection
- Universal, (Movies or Alternative content)
- Interoperable between manufacturers
- Multiple transport mechanisms
- High Security of content and access tracking
3
EDCF-CUser requirements continued
- Upgradeable Systems
- Reasonable cost
- Quality Tiers
4
Applications that can use Digital Technology
- Large Screen first run Cinemas
- Small Screen first or second run Cinemas
- Regional Community Cinemas
- Multipurpose Community Venues
- Event pubs etc
5
Large Screen First Run
- State of the Art Technology
- Potential for fashionable obsolescence
- Heavily influenced by US Studios
- Currently a mixture of proprietary and
standardised technology - Media Security a big issue
6
Small ScreenFirst or second run
- First run needs to be the same quality as Large
screen with lower cost package - Consumer should not be disadvantaged
- Second Run may have lower quality standards
- Dual level security may be feasible
7
Regional Community Theatres
- Restricted use or portable systems
- Venue Shared with other art forms
- Centralised Programme distribution for live
events - Centralised packaged Media distribution for
synchronised events
8
Multi PurposeCommunity Venues
- Sports Center Venues
- Movies
- Concerts
- Sports events
- Support for live interactive
9
Standards Bodies
- SMPTE Society of Motion Picture and Television
Engineers - ITU International Telecommunications Union
- DVB Digital Video Broadcasting
- MPEG Motion Picture Experts group
- Others
10
EDCF
- The EDCF is not a standards body
- The EDCF polls user requirements and matches them
to existing standards - If no appropriate Standard exists or a Standard
needs modifying the EDCF will make
recommendations to the Standards bodies
11
Existing work
- MPEG already covers the lower levels of
Electronic Cinema, EDCF has advised that profile
extensions may be required - DVB already covers the lower levels of Electronic
Cinema. DVB may or may not wish to extend its
work - SMPTE is currently working towards some new
standards - The ITU is working on TV based standards which
may not be appropriate for the Highest level
12
Technology Levels
- Level 1 Application level of digital projection
and presentation matching or exceeding the
capabilities of existing 35mm film in terms of
colour, contrast and resolution.. Used for
digital cinema presentations. - Level 2 Application level of digital projection
and presentation equivalent to standardized high
definition television (HDTV) specifications (for
example 1920/1080/24P after visualy lossless
compression). Used for current digital cinema and
electronic cinema presentations. - Level 3 Application level of digital projection
and presentation equivalent to enhanced standard
definition (EDTV) specifications. Used for
electronic cinema presentations. - Level 4 Application level of digital projection
and presentation equivalent to standard
definition (SDTV) specifications. Used for
electronic cinema presentations.

EDCF Module Interface
- EDCF-T Carrying out Audit of Technology
- EDCF-C Working on level 1 and 2 Commercially
- EDCF-T Will advise EDCF-C on best approach to
achieve level 2 in the short term, Level 1 in the
future
14
EDCF-TTopic Groups
- Mastering
- Image Compression
- Transport and Delivery
- Security
- Theater systems
- Audio
- Projection systems
- Server systems
15
Pending Studies
- Projector Technology Evaluation
- Compression System Evaluation
16
Conclusion
- Digital Cinema can be rolled out with existing
technology - The Cost will drop in the near future with a
standardised approach and technology development - Care is needed to segregate applications into
commercially viable entities.
