1 PrestoSpace Fast, Affordable, high Quality Preservation Technologies & Services for Audiovisual Archives An Integrated Project in FP6 Daniel Teruggi, INA

2 Fast, Affordable, high Quality Preservation Technologies & Services for Audiovisual Archives 2 PrestoSpace PrestoSpace – Objective To offer to televisions, radios, private companies, institutions, small archives, general public, the possibility of developing a patrimonial initiative centered on preservation and exploitation of their audiovisual archives. This will be achieved through technological and industrial innovations, and will be implemented by ensuring the set-up of facilities and services that will provide to these actors an integrated, efficient, scalable and affordable preservation service.

4 Fast, Affordable, high Quality Preservation Technologies & Services for Audiovisual Archives 4 PrestoSpace PrestoSpace - an Integrated Project FP IST 1st Call Open 17/12/2002, closes 24/4/2003 Strategic Objective Technology-enhanced learning and access to cultural heritage

5 Fast, Affordable, high Quality Preservation Technologies & Services for Audiovisual Archives 5 PrestoSpace PrestoSpace for All Broadcasters have already invested considerable efforts in preserving and making their collections accessible Effort still required Small archives crucially need help

6 Fast, Affordable, high Quality Preservation Technologies & Services for Audiovisual Archives 6 PrestoSpace Size of the problem Richard Wright, BBC Information&Archives

7 Fast, Affordable, high Quality Preservation Technologies & Services for Audiovisual Archives 7 PrestoSpace The survey of ten major archives found: 1 million hours of film 1.6 million hours of video recordings 2 million hours of audio recordings Total European holdings of broadcast material are probably 50 times larger Total European AV holdings are at least double Most of it is: 1) original; 2) analogue; 3) at risk. PRESTO Survey of Broadcast Archives Holdings:

8 Fast, Affordable, high Quality Preservation Technologies & Services for Audiovisual Archives 8 PrestoSpace Preservation Status: Obsolescence: At least 2/3 of the material in archives cannot easily be used in its existing form Deterioration: Approximately 1/3 of the material has one form or another of deterioration Fragile media: Roughly ¼ of the material cannot be released for access because the media are too easily damaged

9 Fast, Affordable, high Quality Preservation Technologies & Services for Audiovisual Archives 9 PrestoSpace Example : BBC transfer costs Audio: 7000 hrs/year at 900k Euros Roughly 130 Euros / hr Also spent 10M Euros on sepmag 1” & U-matic: 40k items/3 yrs at 10M Euros 250 Euros / item; roughly 450 Euros / hr News film: 43k items/3 years at 3M Euros 75 Euros / item; roughly 1500 Euros / hr 10% of total project cost is cataloguing 15% is complete manual checking of the result 50% is the “preservation transfer” (staff & equip) 25% is everything else: finding, transport, mgmt

10 Fast, Affordable, high Quality Preservation Technologies & Services for Audiovisual Archives 10 PrestoSpace Results of the Presto Project Effective Preservation needs a process, not just good individual items of technology Savings of 2/3 can be made with fullest overall automation and with elimination of technical bottlenecks Much more research needed on video, film & metadata preservation processes and technology Access, new business and transformed business are the most important preservation issues For many of these issues, real progress needs action on a European scale: technology, rights …

11 Fast, Affordable, high Quality Preservation Technologies & Services for Audiovisual Archives 11 PrestoSpace The Solution: Presto Space Preservation Service Involve all audiovisual collections Profile of user needs Improve audio, video, film and metadata technology Integrate into an efficient workflow Offer a Service to meet those needs Tailored to user profile Better, Faster, Cheaper than at present

12 Fast, Affordable, high Quality Preservation Technologies & Services for Audiovisual Archives 12 PrestoSpace Why an Integrated Project ? Research areas Playback optimisation, restoration, process optimisation... Integration Storage, Delivery & access, Metadata... Developing tools that work Exploitation Selling the tools Ensuring the set-up of actual services before the end of the project

13 Fast, Affordable, high Quality Preservation Technologies & Services for Audiovisual Archives 13 PrestoSpace Relevance PrestoSpace is fully within the scope of Strategic Objective : Technology-enhanced learning and access to cultural heritage Audiovisual Heritage is supported by the most fragile of all media : film, videotape, audio tape, audio discs
