1 Preserving TV & Broadcast Archives June 2002 Adrian Williams

2 Size of the Archive The BBC has one of the largest multi-media archives in the world 1.75 million items of film and videotape 800,000 radio recordings 3 million photographs 1.2 million commercial recordings 4 million items of sheet music 22.5 million newspaper cuttings 600,000 document files 20,000 rolls of microfilm 500,000 phonetic pronunciations

8 EC Project Presto GOAL: reduce preservation cost 30% 24 months, 10 partners, 4.8 M BBC, INA, RAI 7 technology partners Audio: ACS Video: e-vod, S&W, Vectracom Film: NTEC Subcontracts: Bertin; ITK General: JOANNEUM, ITC/IRST 7 other major broadcast archives in user group SVT, ORF, SWR, NRK, YLE, NAA, TTR

9 Project Management Analysis Phase Implementation Phase Break point! WP 4 Audio Digitisation WP 2 - User Requirements WP 3 - System Requirements WP7: Metadata Integration Size and urgency of problem Technologies state of the art Key Link Technology WP 5 Film Digitisation Organisational Models Analysis Process Analysis WP7: Metadata Key Link Technology Integration System Integration & Test WP 6 Video Digitisation User and Market functional Requirements System Specifications WP7: Metadata Integration Key Link Technology Evaluation, Exploitation & Dissemination

11 Process Requirements End to end process Identification of costs Development of cost effective approaches to batch processing Examples are:- automatic quality-checking equipment software for overall control of end to end process purpose built preservation areas to optimise equipment and streamline movement of material investment in in-house rather than contracted facilities Links to the wider business process (part of the overall information & media flow of a broadcaster) Link to future business ( the future archive) It is vital to the future of broadcasting and broadcast archives to have an increased appreciation of the value, not just the cost, of new technology

12 Cost per use: true cost of an asset is a total life-cycle cost 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 Film Video Audio Digitisation and mass storage is about 50% more expensive, but is expected to double usage of an asset The value of an item must be four times the preservation cost to be financially viable One minute of sold or re-used archive material will pay for preservation of one hour of archive material

13 Key links developed by PRESTO Audio Film Video Metadata 14 Detailed Reports; all on the Workshop Proceedings CD & Website

14 Audio Software: Audio Quality Monitor (ITC-irst) Document: Audio Transfer Process (ACS) Device: Audio Playback Improvement (RAI) Tests: Audio Lossless Compression (RAI)

15 Film Device: Auto-resplice machine (INA; Bertin) Document: Sustainability of Broadcast Film Archives (ITK) Software and Specification: High Quality Format Conversion (JOANNEUM) Tests: Lossless and near-lossless compression for film (and video) (JOANNEUM)

16 Video Devices: Digitisation quality monitoring / logging (INA, Vectracom, ITC-irst) Device: Time base corrector with drop out detection and compensation (S&W) System Integration,Tests and Document: Multilevel encoding (e-vod)

17 Preservation and Distribution : the video transfer chain Workflow Shelves Preparation (handling, cleaning, labelling, specific processes) Loading, Playback, unloading Time Base correction, decoding, conversion to digital Digital Betacam Checking Digital Betacam Loading, Playback, unloading or Digital compression and encoding Files on servers (browsing, delivery quality), or shelves (delivery, archival) Checking

18 Metadata management Documents Metadata and the Preservation Workflow (the workflow IS metadata management) Guide to Metadata (how to use metadata to reduce costs and increase quality, and not get lost in the maze of metadata standards) Software: Common access to broadcast archives (Broadcast OPAC; using standards)

19 Conclusion! Everything online now is impossible! Browsing quality within seconds starts to be possible on large databases! Usable quality within minutes on selected samples possible! When transferring! Make a high quality copy! Make a browsing quality copy, put it on line! Put effort on indexing! Work to prepare a near-on-line copy! Have a years plan...

20 Conclusion Europe requires a dedicated preservation factory
