  1. 1. Introduction for File-based Workflows MJ Drouin, VSF meeting October 4th 2011, Atlanta
  2. 2. Who Am I?• Director with 15 years of Media experience, I lead technical teams of up to 30 people and 3 managers to deliver most aspects of the business - Operations, Customer Services, Information Technologies, Project Management, Engineering, and Procurement. I developed expertise in managing cable, wireless, satellite, transmission, engineering and software development. I worked at Bell, Teleglobe, Intelsat, CBC and as a expert consultant.• Professional Engineer, Masters in Technological Management, ITIL foundation, PMP• I have extensive experience in speaking since the 90s (ouf!), subjects were always a mix of technologies, commerce and management. – Past engagements included: Cloud computing training for Content Providers (2011), My video is a file, now what? (2010), DVB-H: Video over IP goes wireless (2010), Service Oriented Architecture (SOA): Tutorial for the Broadcast Community (2010), Pitfalls of SW development: What every executive should know (2009), 8 weeks on Twitter: I love it! (2009), The Future of Broadcast Archive Systems (2008), DVB-H: Video over IP goes Wireless (2006), HDTV distribution (2005), Video over IP (2004) and, Several broadcast technical training (1994-1998): Video 101, Digital Video and Compression 201, Video testing techniques 301.• http://www.linkedin.com/in/mjdrouin• http://twitter.com/mjdrouin2011-10-04 MJ Drouin© - VSF Meeting 2

  4. 4. Agenda• Traditional vs File-based Workflow • FIMS: Phase 1 objectives• Implementation of File-based – SOA Workflows – Broadcast workflow in small services: – Roadblocks Cloud Computing? – Pains • What’s Next? – Facilitators – Paper, hand-made, multi-interface unrelated environment• MXF: The Basics – Linking Open Data Project – Advantages – The rest of the world is moving: Web – SMPTE MXF standards 1.0, 2.0 and 3.0 – Partition pack – Linked data: Creating new things – Played Material vs Saved File – Operational Patterns – MXF on your HDD: AS-02 – Types of MXF files2011-10-04 MJ Drouin© - VSF Meeting 4

  7. 7. Roadblocks for its Implementation• Skills• Split IT & Broadcast departments• Requires – again – a brand new infrastructure• Lack of standards, interoperability• Mostly specialized broadcasters who really do it• Metadata management not integrated, yet2011-10-04 MJ Drouin© - VSF Meeting 7

  9. 9. Pains during its Implementation• Ingress • Video on computer vs on• Egress screen• Equipment flexibility and • Quality of source not age easily separated from• Not-really standard encoding & file transfer standards such as AVI • OU Data circuits• Scheduling & Automation: Yet again, • Software offering = only other software needed to large systems – not yet as make it work… services2011-10-04 MJ Drouin© - VSF Meeting 9
  10. 10. Facilitators• More than 1000 pages of standards (SMPTE/AMWA/FIBS/EBU)• Economics• Non-real-time transmissions• Bandwidth growth in Telecom and Public internet• Mobile tools: Intelligent phones & Tablets• Content creators pushing for ubiquity• MXF … Hybrid environment is here to stay a little longer…2011-10-04 MJ Drouin© - VSF Meeting 10

  12. 12. Advantages MXF• Shared essence • But…• Everybody that works on • What’s real, today? it builds metadata content• Open standard – independent of platform, OS, vendor, etc• Create a web of linked essence/data2011-10-04 MJ Drouin© - VSF Meeting 12

  23. 23. Now that you split the workflow in Services…• You can outsource it and grow utilisation of 3rd party ressources … on demand?• Cloud computing?Could be another Operational Model for MXF?May make it easier for Broadcasters to invest/or not in the required additional infrastructure…2011-10-04 MJ Drouin© - VSF Meeting 23

  27. 27. Possible to look more like that?• Don’t you think it will look more like that than pure SOA with a super-centralized enterprise bus & Servers?2011-10-04 MJ Drouin© - VSF Meeting 27
  28. 28. The rest of the world is…• Web 1.0 = content to all• Web 2.0 = bidi web, content from users as well as producers (read / write) web• Beyond? Web 3.0 – web = services – Intelligent data = Structured info = Links and filters – Beyond PC: Mobile, IPTV, etc – Web of things: Machines sending info on the web2011-10-04 MJ Drouin© - VSF Meeting 28
  29. 29. Isn’t it what a lot of people do at Broadcasters? • Linked Data enables data to be opened up and connected so that people can build interesting new things from it. (via Tim Berners-Lee) Linked Data is Blooming; ReadWriteWeb, May 2009 MJ Drouin© - VSF Meeting2011-10-04 29
