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

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

Network Coding and

Reliable Communications Group

• Community Generated Programming

– The cyber-living room

– The cyber-pub

Social Viewing

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

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

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
