JPEG 2000 a Great Step Forward for the Archival Community
From IT Broadcast and Digital Cinema http://fullres.blogspot.com/
The Digital Preservation Coalition has examined JPEG 2000 in a report published today. The report concludes that JPEG 2000 represents a great stride forward for the archival community. The format now allows for greater compression rates and a recompression rate that is visually lossless.
The findings come as the Digital Preservation Coalition launch its latest ‘Technology Watch Report’ written by Dr. Robert Buckley, a
research fellow with Zerox *‘JPEG 2000 – a practical digital preservation standard?’* http://www.dpconline.org/docs/reports/dpctw08-01.pdf. The report looks in-depth at the new format and the challenges it has to cope with. JPEG 2000 is widely used to collect and distribute a variety of images from geospatial, medical imaging, digital cinema, and image repositories to networked images. Interest in JPEG 2000 is now growing in the archival and library sectors, as institutions look for more efficient formats to store the results of major digitisation programmes.
The report is aimed at organisations involved in the management and storage of digital information. The in-depth report will help archives, libraries and other institutions make informed decisions about JPEG 2000 format and their future storage needs.
JPEG 2000 can reduce storage requirements by an order of magnitude compared to an uncompressed TIFF file. Dr.Buckley, says, “This new format has come at a time of heightened awareness about access to digital documents. Any format that can assist archives and libraries to do this is welcome.”
The format will also enable users to open as much of the file as they need at that time. This means a viewer, for example, could open a
gigapixel image almost instantly. This is achieved by retrieving a decompressed low–resolution display sized image from the JPEG 2000
codestream. Coupled with this, the users ability to zoom, pan and rotate an image has been enhanced.
The report concludes that JPEG 2000 offers much more flexibility and features than JPEG, but at the cost of greater complexity. It is however a great stride forward, and of major significance for the information management community.

European Digital Cinema Security Whitebook is Online

This book results from the work of the *Enhanced Digital Cinema* (EDcine) project established by the European Commission in the context of the Networked Audio Visual line of the 6th framework of IST (Information Society and Technology). The world of digital cinema has been led by Hollywood initiatives. The Digital Cinema Initiative (DCI) is under standardisation by a subgroup of the Society of Moving Pictures and Television Engineers, namely the DC28. EDcine was
launched in this environment to maintain the European industrial leading edge in the field and to develop new tools and best practices beyond the Digital Cinema Initiative (DCI). Economic, cultural and technical aspects are more complex in Europe. There is a clear need to go beyond DCI. In its initial functional analysis, EDcine included end-user groups, such as small production studios, local post-production
facilities, small and big distribution networks from large multiplexes to small arthouse cinemas, and cinema archives. It was then deemed necessary to settle the key digital cinema security questions in a “White Book”.
