Preserving the Value of Broadcast Archives EC Project PRESTO: Preservation Technology (for broadcast archives) Prepared for the DG- INFSO IFLA 2003 -- Berlin
“You can’t re-use what you didn’t keep” • Content and Value of Broadcast Archives • Preservation: • Status • Project Technology & Costs • & Access: costs & benefits • & Restoration • EC Project PRESTO • Technology (just a bit) • Preservation and creation of assets you can re-use
EC Project PRESTO • GOAL: reduce preservation cost 30% • 24 months, 10 partners, 4.8 M€ • BBC, INA, RAI • 7 technology partners • Audio:ACS • Video: EVOD, S&W, Vectracom • Film: NTEC (also ITK) • General:Joanneum, ITC/IRST • and SVT, ORF, SWR, NRK, YLE, NAA, TTR Vectracom
Holdings: The survey of ten major archives found about 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 AT LEAST ten times larger: 10 million hours of film 20 million hours of video 20 million hours of audio
Value of the Content • Unique cultural and historical record of the 20th Century (paid for by licence fees) • BBC: Sound archive: 1922 onward; Churchill; TS Eliot; Abdication speech, Radio One “Sessions” … • Film: news before 1980; major drama; Man Alive, 1984, Ascent of Man, British Empire, Omnibus … • 2”: Dr Who, Dad’s Army, Steptoe & Son, Forsythe Saga, Fawlty Towers, Secret Army … • 1”: Yes Minister, Eastenders, Angels, Wogan, All Our Working Lives … • U-matic: News 1982-1990’s:Lockerbie, General Elections in 1983 & 1987, the Gulf War … • Commercial value: 100 – 500 € per minute (or more)
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
Obsolescence • Videotape • 2”; 1”; U-Matic: no playback equipment • Film • Disappearing in post production • Audio formats • Grams : no playback equipment • ¼” ?
Deterioration • Videotape – decay of adhesive • 2”; 1”; U-Matic (30% read failures at BBC) • Audio – decay of adhesive • ¼” tape (depends upon brand) • Magnetic sound tracks • Vinegar syndrome • Other Acetate – other sources of acetic acid • Decay of film splices • General decay of polymer materials
Fragile Media • Vinyl • and shellac • Film • 10 plays per print (videotape: 50) • Video or audiotape can easily be physically damaged or affected be magnetic fields
Actual Transfer Costs In Euros Per hour of material (averaged over lots of holes) 1 item = 20 minutes
Preservation work • Total film preservation hours per year: • 8 000 plus 10 000 sepmag • Total Video preservation hours per year: • 36 000 • Total Audio preservation hours per year: • 20 000 from BBC, INA, NAA, ORF plus 25 000 at RAI • Total Intake of new material per year: • 4 000 hours of film • 170 000 hours of video = 4x rate of preservation • 80 000 hours of audio = 4x rate of preservation
Preservation work- not keeping up! • Total film preservation hours per year: • 8 000 plus 10 000 sepmag • Total Video preservation hours per year: • 36 000 • Total Audio preservation hours per year: • 20 000 from BBC, INA, NAA, ORF plus 25 000 at RAI • Total Intake of new material per year: • 4 000 hours of film • 170 000 hours of video = 4x rate of preservation • 80 000 hours of audio = 4x rate of preservation
Preservation Funding • In General - Broadcast Archives have NO standard funding for preservation • Commercial basis (business case): • solid for most broadcast archive material • harder for both film and audio • Heritage basis: • again, no standard funding
Cost / Effective Preservation Main issue – the overall process • Mass transfer – assembly line • Model: RAI: 200k hours in 2.5 yrs • ‘on-demand’ preservation can seem free, but true cost is approx 3x GREATER than cost using an efficient mass transfer process • Key factors: quality, metadata
Making the Savings • Purpose-built preservation areas to optimise equipment and streamline movement of material • Dedicated ‘preservation’ facilities • In-house or commercial • Links to the wider business process ·programme documentation ·subtitle information ·rights clearance ·creation of new metadata to improve catalogue ·extraction of key frames ·automatic speech recognition
Cost per use: • total lifecycle cost • True cost of an asset is total lifecycle cost. • True benefit is related to the number of times that asset is used over the lifecycle. Archive preservation strategy: • “lowest cost per use” over the life cycle of the new media, • NOT the lowest transfer cost.
Access: examples • Video on servers at SVT: • in operation for less than a year • Probably 2 to 3 times greater usage • BBC – examples for preservation work • 2” to digibeta – at least 3x greater usage • Similarly for news film onto videotape • BBC News 24 online archive pilot: • 600 items online: 5 “to air” per day • 120000 items offline: 30 “to air” per day

BBC Radio One ‘sessions’ • Popular music recorded at BBC over 30 year period • No accessible catalogue; no backup; no circulation • => NO USAGE • Preservation project fixed all these issues • => launch of new radio channel (Radio 6) based mainly on this material
Two aspects of Assets and Preservation • Even Managed Assets need preservation • Too easy to forget about the long-term future of your assets • Preservation Projects offer archives their main chance to introduce asset management • Several billion Euros will be spent on broadcast archive preservation in the next decade (€100M by the BBC!)
The Opportunity:re-write the archive • Transform technology • Create ASSETS from holdings • Improved access: • Use new technology for current services • create new services
Transform technology • Reduce cost • Storage • Maintenance • Workflow • End-User research • Electronic delivery
Create ASSETS from holdings • Catalogue • Complete • Detailed • Synchronised • Rights • Owners • Uses • Digital Rights Management
Improve current services • At the user’s desktop • Catalogue • Browse • Edit / annotate / select • Order master material • Receive master material
Create new services • External access • Commercial • Public service
Technical requirements • Multi-level digitisation • Edit, Browse, Web • Segmentation • Key frames • Speech / music / effect / speaker • Supporting content-based retrieval (CBR); • Speech recognition • MPEG-7 • Digitisation of ‘related materials’ • Linking media to related materials
What we don’t do as part of preservation • Restoration • But- define what needs restoration • Rights clearance • But- get the documentation together, and coded into ‘rights taxonomy’ of owners, users, uses • Pay the full bill • Archive is at centre of whole digital workflow • All interested parties share costs and benefits
Problems with funding for improved access: • cost-benefit evaluations of future requirements • business case for transforming archive technology Requires managerial vision: a commitment to “tapeless working” in broadcasting
In conclusion Preservation transfer process: • A chance to do all the technical work to support the archive of the future • Including greater commercial exploitation
