2007 EBU Training VRT Newsroom interoperability

  1. 1. Ensuring interoperability: “la grande besogne” EBU visit to VRT integrated newsroom g Johan Hoffman - 13 December 2007

  3. 3. Background VRT has adapted its organisation to a new enterprise strategy, which will help it being successful in the context of p g – increased competitive pressure – fast evolving technology, both on producer and consumer sides – changing consumer behaviour – increased and new opportunities (new media, HD, …) – a changing market environment VRT is aligning its media production on the corporate strategy, implying – increased pressure on cost – reduced production times p – more repurposing of content – integrated and cross-medial production The Th news department is a forerunner in these trends. d t ti f i th t d
  4. 4. Needs and requirements In order to reach its objectives, VRT needs new digital p production methods. Within radio and television production, the media are already digital… – With the advantages of higher quality, enhanced possibilities. But storage, transport and copying of content is essentially like it was in the analogue world world. – Physical handling and transport of tapes We need a fully integrated file-based workflow. Technology innovation makes this possible.

  6. 6. DMF objectives Moving from tapes, CD’s, cassettes to files stored and conserved on a central system. y At the same time supporting all existing craft work processes. Easier creation, maintenance and communication of essence-related metadata throughout the production process. t d t th h t th d ti Introducing new, more efficient or less time consuming workflows. Supporting easy repurposing reuse and distribution of content across repurposing, media (radio, television, online). Cost efficient and future-proof technology investment – Move to standardized technology where possible (e.g. file servers, network)
  7. 7. Guiding principles Full file based production from start to finish. ( g ) – Raw material starts its life as a file (e.g. in a file based camera) – Or, it is ingested and converted to a file as the very first step (in case of reuse of legacy tape based archive material) Support for cross-medial reuse and repurposing throughout cross medial all production stages. Fully integrated workflow workflow. – Automated transfer of essence and metadata through all production steps – F ll t h l Full technology support f th production workflow t for the d ti kfl

  10. 10. Architecture principles The DMF consists of a central system for media storage and media asset management, and a number of craft work centres. centres Craft work centres and central media management are “best of breed”. – No single vendor shopping – Best tool for the job W k centres and central media management are loosely Work t d t l di t l l integrated and can operate autonomously. – Halt propagation of technical incidents – Emergency workflows available Integration is key. – W want a media f t We t di factory, not just a bunch of tools. tj t b h ft l

  25. 25. Experience: MXF Some maturity problems remain. MXF is a very (too ?) broad standard allowing many combinations and standard, flavours. Interoperability on essence level not guaranteed by using MXF. MXF is necessary, but not sufficient for essence interoperability. Specific care has to be taken to specify/ensure support for the exact flavour used used. Even with the flavour specified, implementations were in many cases not error-free. At least one expert with a high level of MXF specialised knowledge is needed. Vendors are willing to improve their implementations implementations.
  26. 26. Experience: integration The integration platform is the key to obtaining a well- p performing factory, allowing to align the components and g y, g g p their use on the business process. A common data model is necessary. The design phase of the integrations is time consuming, but the development cycle is relatively short. The i t Th integration architecture should provide components ti hit t h ld id t isolating weaknesses and immaturities in craft tool implementations. Future DMF extensions will profit strongly from the integration platform.
  27. 27. Experience: storage and networking Building storage and the supporting network is far from trivial. trivial Demands on file storage capacity, guaranteed bandwidth and reliability are high y g – Technologically within reach of standard (IT-) components. – But they exceed the typical experience of IT infrastructure build people. people – Therefore, careful design and test is necessary, as well as challenging “easy” assumptions. Storage and networking are projects in their own right.
  28. 28. Experience: user requirements User requirements – are unclear in the beginning – tend to shift as understanding increases. A good dialogue and cooperation with users is essential essential. – Give clear feedback on what technology can and can’t do. – Organise demo sessions as early as possible. – Involve users in testing.
  29. 29. Experience: effort and complexity A very high level of effort and involvement from the technology department is necessary over a p gy p y prolonged g period of time. – Other investments are delayed due to lack of people or funding. – This takes its toll on people people. Complexity is inevitable, and needs to be managed. – Regular p j g project team meetings g – Architecture board During the final phases of the project, the support department is h d t t i heavily l d d il loaded – High training effort over a short time period. – Intake of the new tools and technology. – Maintaining the old systems until phase-out.
