1 Preserving the Value of Broadcast Archives EC Project PRESTO: Preservation Technology (for broadcast archives) Prepared for the DG- INFSO IFLA 2003 -- Berlin

2 You cant re-use what you didnt 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

3 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 EC Project PRESTO

4 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

5 Archive Audio Holdings

6 Archive Film Holdings

7 Archive Videotape Holdings

8 Value of the Content Unique cultural and historical record of the 20 th 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, Dads Army, Steptoe & Son, Forsythe Saga, Fawlty Towers, Secret Army … 1: Yes Minister, Eastenders, Angels, Wogan, All Our Working Lives … U-matic: News 1982-1990s: Lockerbie, General Elections in 1983 & 1987, the Gulf War … Commercial value: 100 – 500 per minute (or more)

9 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

10 Obsolescence Videotape –2; 1; U-Matic: no playback equipment Film –Disappearing in post production Audio formats –Grams : no playback equipment –¼ ?

11 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

12 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

13 Actual Transfer Costs In Euros Per hour of material (averaged over lots of holes) 1 item = 20 minutes

15 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

16 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

17 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

18 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

19 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

20 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.

21 Like for like preservation life cycle cost p/hr Usage over life cycle Cost per use Mass storage preservation life cycle cost p/hr Usage over life cycle Cost per use Film20005400300010300 Video2005403001030 Audio1205241801018 Cost per use: true cost of an asset is a total life-cycle cost Digitisation and mass storage is about 50% more expensive than cheapest transfer to new media, but is expected to AT LEAST double usage of an asset

22 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

24 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

25 Preservation & Restoration Archives are NOT committed to keeping the original artifact They are committed to warts and all copying They have NO funding for restoration work –Needs item by item commissioning of funds –Except for simple, cheap, real-time processes that be built into preservation transfers –eg: vinyl transfer -- noise and click removal

26 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!)

27 The Opportunity: re-write the archive Transform technology Create ASSETS from holdings Improved access: –Use new technology for current services –create new services

28 Transform technology Reduce cost –Storage –Maintenance –Workflow End-User research Electronic delivery

29 Create ASSETS from holdings Catalogue –Complete –Detailed –Synchronised Rights –Owners –Uses –Digital Rights Management

30 Improve current services At the users desktop –Catalogue –Browse –Edit / annotate / select –Order master material –Receive master material

31 Create new services External access –Commercial –Public service

32 programme documentation subtitle information rights clearance creation of new metadata to improve catalogue – item level access extraction of key frames automatic speech recognition Process Efficiency: Links to the wider business process

33 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

34 What we dont 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

35 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

36 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.

37 In conclusion Preservation transfer process: A chance to do all the technical work to support the archive of the future Including greater commercial exploitation
