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)

10
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
