Presentació que anava a realitzar Marie-José Montpetit, investigadora en SocialTV al MIT (Massachusetts Institute of Technology), dins de la jornada "CÚbicS: La transformació dels mitjans audiovisuals" al voltant del concepte "Social TV". Tot i que finalment no va poder assistir, ens autoritza la difusió del contingut. La jornada es va realitzar el 2 de desembre de 2010 a l'Auditori del CaixaForum de Barcelona.

TV Experiences
• Mobile
– Not just device and networks but people
• Social (personal)
– Not just people but devices and networks
• And more and more IP based
– Both OTT and managed
The “anywhere/anytime/any device”
World is upon us

Disruptions
– Enhanced and interactive experiences
– Co-creation and story-telling
– Leveraging time and place shifting
– Device ecosystem
– Novel interactivity devices
– Heterogeneous Technology Internet
– Wireless does not mean mobile
– Peer to peer getting “out of prison”
– Applications everywhere
– High Bandwidth Experiences
– and 3D

An Overview

Hypotheses
• Devices do not end at their shells
– But can combine their features
• Networks do not end at the gateways
– Use the home/edge resources
– Provide context and use locality
• Protocols should allow the melding of
information not defend the border

12. Network Coding and
Reliable Communications Group
Social TV:
more than tweets to the TV
• Social TV linking people
– Content/stories
– Interactions
• Social TV connecting devices
– Not a device an ecosystem
• Social TV composing networks
– Enabling the edge

Social Content
– Connects the community across generations and
continents
• Use the TV screen as a familiar window on the Web
• Web 2.0 as a familiar interactive medium for content
creation

14. Network Coding and
Reliable Communications Group
Social Viewing
• Community Generated Programming
– The cyber-living room
– The cyber-pub

15. Network Coding and

User Experience is KEY

Composing Networks and Devices
– Some goals:
• Reduce delay in downloads especially for video and
converged applications
• P2P extended to multiple networks
• Assumes information is distributed in the “community”
• Enables multi-definition of “cost”
– Example Algorithm:
• Start download on the “cheapest” network
• When delay goes above a certain threshold
– “Borrow” on another network

Examples
• Deployments/demos
– ITV Live (during the World Cup)
– ExMachina
– Living Labs
• Technology
– Boxee
– GoogleTV
– Yahoo Connected TV
– Others (startup of the week!)

Our Research (1)
• Rediscover networking
– Collaborative applications
– Content distribution architectures
– Network/device interconnectivity
– Green networking

22. Network Coding and
Reliable Communications Group
Our Research (2)
• Rediscover information
– Trade transmission and storage: video is
information
– Recognize the importance of network ecosystems
– Enable efficient content distribution at the edge
– Develop content protection that protects rights
and privacy not business cases

23. Network Coding and
Reliable Communications Group
Conclusion
• Future of TV: Internet, mobility, social
networks
– Linking people, devices and networks
– Liberating content from devices, time and space
– Co-creation and advanced storytelling
– New business models
