  1. SDN – Story Delivery NetworkLocation-dependant object-based media-streaming using Publish-Subscribe ontologies

  2. Outline • Current media distribution status – what’s the problem? • Example of a stakeholder use case • What is the SDN? • Basic graphic representation • Demonstration Stuart Porter (CTVC) and Dr Ben Tagger (UCAM)

  3. Current media distribution status • Thanks to the internet, media is consumed everywhere • Over 4 billion hours of video are watched each month on YouTube [1] • Specifically, with the increase of hand held devices and tablet computers, media consumption is increasing at a massive rate • Vimeo traffic from mobile devices increased 350% in 2011[2] • The increase in social networks is also driving consumption – over 500 years of YouTube video are watched on Facebook everyday[3] Stuart Porter (CTVC) and Dr Ben Tagger (UCAM)

  4. So? What’s the problem? • This means media producers increasingly have to deal with new legal and ethical issues. • Who can watch our content? • When can our content be shown? • Where is our content legal? • What are our responsibilities if our content is shown somewhere where it is illegal? • In the current internet, it is easy for any user to access any content – which puts media producers at risk. • So how can media producer maximise their viewers without breaking the law around the world? Stuart Porter (CTVC) and Dr Ben Tagger (UCAM)

  5. A Stakeholder Use Case • CTVC has been commissioned to produce a film for a UK broadcaster • CTVC sells the rights to the film internationally • During production CTVC films its own footage of interviews etc. • CTVC also sources third party content from libraries • However, some of the content from the libraries cannot be show in international territories… • …so CTVC must make several versions of the same film. Stuart Porter (CTVC) and Dr Ben Tagger (UCAM)

  6. A Stakeholder Use Case cont… • In the current internet this is time consuming and expensive • CTVC would re-edit the UK version, lay a new sound track and output new files Stuart Porter (CTVC) and Dr Ben Tagger (UCAM)

  7. Querying for Media Pursuit… Blackadder… Dissemination… HD subscription (EDL) Video… over 18 UCAM Summer School Promo Middleware/Blackadder/Publishers SDN (Player) query Stuart Porter (CTVC) and Dr Ben Tagger (UCAM)

  8. The Edit Decision List (EDL) Clip #1: [source_media] [start_time] [end_time] clip 1 metadata Clip #2: [source_media] [start_time] [end_time] clip 2 metadata UCAM Summer School Promo Clip #N: and so on….. clip N metadata programme metadata check for consistency

  9. Re-stitching the Subscriptions CTVC AUEB UCAM

  10. Why ICN Helps? • Media files hold information • Metadata can prevent media being accessed if certain conditions are met • content marked “adult only” cannot be accessed by users under 18 • content tagged “not Saudi Arabia” cannot be accessed in Saudi Arabai • Content tagged “after 8pm” will not work before 8pm in what ever time zone the user is in Stuart Porter (CTVC) and Dr Ben Tagger (UCAM)
