Statement

• Networked media and Future Internet is moving
  towards a combination of available (SotA) and new
  technology
• Research should focus on
• Emerging innovative ideas and approaches
• Integration of these with available techniques
  and paradigms
• The following are four SotA and emerging
  technologies that should be considered when
  defining thematic priorities in Networked Media

3
Thematic priorities in Networked Media

• Intelligence at network nodes

• Facilitating P2P communications

Suitable computational power at least at some
network nodes Storage capacity and decision
making capability at network nodes

• Scalable content coding

Source and channel coding should be scalable,
hierarchical to allow seamless transmission over
heterogeneous networks

• Considering social connections and implications

4
Intelligence at the nodes

• Current nodes (routers) just store and forward
  packets
• There is almost no processing at intermediate
  nodes
• Information-theoretic limits can be overcome by
  allowing nodes to perform non-trivial operations
  on packets
• Network coding
• puts more intelligence at the nodes
• execute coding operations on content, in addition
  to routing
• enables new communication systems architectures
• a very promising approach for re-designing future
  networks and substantially improve their
  performance
• allows trade-off communication capacity against
  comput. costs
• It brings significantly benefits in terms of
  throughput, reliability and fault tolerance

• Scalable content coding adaptable to
• heterogeneous
• networks
• dynamic traffic
• end user
• devices

8
Social P2P technology

• Social network analysis
• Mapping and measuring relationships and flows
  between people, groups, organizations, etc.
• The nodes in the network are the people or groups
• The links show relationships

With added value services/applications

• Temporal tag integration (learning)
• Temporal generalization (tag a frame given tagged
  neighboring frames)
• Temporal segmentation (into tag-based shots)

Conclusion

• In defining thematic priorities in Networked
  Media, a combination of available (SotA) and new
  technology should be considered
• Research should focus on emerging innovative
  ideas and their combination with available
  techniques and paradigms
• Thus, thematic priorities in Networked Media
  should include
