  2. Pursuit-Essex Workshop 2013 What are we trying to do with ICN? • What is the motivation for this problem? • The Media-Delivery life cycle. • How is the achieved (enabled/facilitated) within an ICN environment? • Links to Demos (no live demo today )

  3. Pursuit-Essex Workshop 2013 The Problem • Rooted in a real media production scenario (at CTVC). • Presents a currently burdensome situation for CTVC. • Cannot be easily (i.e. natively) solved with current architecture. • Our solution: • Reduces workload of media producers. • Provides users with a personalised media experience. • Provides network benefits; enables optimisations, etc.

  4. Pursuit-Essex Workshop 2013 Scenario: The Film… • CTVC want to produce a film (e.g. a documentary): • Footage from CTVC’s archives. • New footage shot specially for this film. • Footage already in the public domain (but not owned by CTVC). • These materials have varying properties and constraints. • Material not owned by CTVC must be licensed. • The outcome is a 47 minute, 4-part, UK film.

  5. Pursuit-Essex Workshop 2013 Extending to other Areas… • CTVC want to sell the documentary to other broadcasters/regions which have varying licensing and timing requirements. • CTVC must generate each version manually. • US/AUS version (38 minutes) • Russian version (47 minutes) • UAE and Saudi Arabia versions (53 minutes)

  6. Pursuit-Essex Workshop 2013 Extending to Digital Distribution… • Required considerations: • Foreign language audio/subtitles, regional advertisements, description tracks for the visually impaired, licensed material. • Now, CTVC want to make their documentary available via digital delivery. • Consider the additional requirements: • High/Low bandwidth versions depending on viewing medium (ie. Mobile vs. HD TV), different bitrates. • Different distributors use different codecs/compression techniques.

  8. Pursuit-Essex Workshop 2013 Some Issues… • (Forgetting delivery) These versions constitute a content-management nightmare. • How does the media producer (CTVC) ensure that the correct version is viewed? How do they protect themselves? • Conceptually, these versions are identified and delivered as monolithic blobs.

  9. Pursuit-Essex Workshop 2013 The SDN • How do we achieve distributed media delivery? • How do we achieve personalised media – i.e. people getting a media experience designed for them? • We are not the only ones looking at this problem. • fMP4, MPEG-DASH, HLS (M2TS) • But we have a solution that: • Engages the network, middleware and application layers. • Manages the metadata of video, audio, clips and films. • Reuses common media and enables network optimisations.

  10. Pursuit-Essex Workshop 2013 So, how do we get media in? Domain Model Annotations Blackadder (ICN) media media publish

  11. Pursuit-Essex Workshop 2013 What are we putting in? • Video, Audio – (MOV, MP4, MPG, blah, blah…) • How do we represent stories in our network?

  17. Pursuit-Essex Workshop 2013 There must be more to it than this..? • Well, yes there is… • We have middleware to • manage the domain model ontologies. • model the mappings between the application and network metamodels. • provide mechanisms for browsing and querying within our pub/sub network.

  18. Pursuit-Essex Workshop 2013 Publishing: From Start to Finish S0 S1 Sn ? … annotate Network Σ(S) Min(S) map merge media prune publish P P

  19. Pursuit-Essex Workshop 2013 How ICN enables the Story Delivery Network… • Everything is information. • Anycast – information comes from anywhere. • Information space modelling. Middleware enables: • Discovery of networked resources. • distributed querying for resources (clips). • consistent information space modelling.
