This meeting takes two of the topics described at the Visit the SMPTE UK Section made to the University of Essex in June 2014.
Professor David Crawford introduces two presentations – on New Networking architectures - ICN -which better suit media transfer and ways of region based image analysis for novel coding regimes
SMPTE members were very impressed by the clarity of the explanation and the possibilities of these technologies.
Information Centric Networking
Martin Reed and Mays AL-Naday will highlight the current evolution of the Internet and why it has motivated the new research area of Information Centric Networking (ICN). The talk will point to the recent growth of the Internet with an increasing number of services and applications as well as growing traffic volume, which is mainly driven by media traffic such as VoD and IPTV.
One of the main concepts of ICN is the redesign of the communication paradigm to establish the communication ties on the basis of mutual information interest rather than end hosts.
Accordingly, ICN allows the network to recognize the carried information and act upon it in such a way as to optimize the network utilization.
After a brief introduction of the ICN concepts, and Project "PURSUIT" as one of the main ICN architectures,they will show the advantages of ICN over the current IP, hostcentric model. Such advancements include: native support of anycast/multicast delivery modes; enhanced traffic services such as resilience and QoS; and reduction of many of the security, privacy and integrity concerns raised by the current Internet architecture.
Finally the plans for deploying ICN using software defined networking will be reviewed.

Regions- Video Segmentation
Binary space partitioning (BSP) is a technique that has been developed in the domain of 3D computer graphics. The structure of a BSP tree enables better analysis of spatial information for objects in a scene, which can be useful in activities like video rendering – enabling information such as objects’ ordering from front-to-back with respect to a viewer at a given location, to be accessed rapidly, for example.
Other applications include performing geometrical operations with shapes in CAD, collision detection for robotics research projects and 3-D video game designs.
This talk will describe some innovative research work in video segmentation techniques to identify salient nodes in a binary partition tree which can be used to represent object candidates for the down-line processing of a video sequence.
Region Based Analysis
Martin J. Reed received his Ph.D. from University of Essex, UK, in 1998. After working as a research officer in the area of multimedia transmission over IP/ATM networks he was appointed as a lecturer at the University of Essex in 1998. His research interests include transmission of ultra-high definition video transmission over networks, the control of optical and GMPLS/MPLS networks, information centric networking and network security. He has been involved in a number of EPSRC and EU projects in these areas and has held a Research Fellowship at BT
Mays F AL-Naday is a researcher at the School of Computer Science and Electronic Engineering, University of Essex. She received her BSc degree in Communication and Information Engineering from the University of Baghdad and received her Master’s degree in Computer and Information Networks from the University of Essex, after which she has been awarded the University of Essex scholarship for PhD. During her PhD, she joined the Network Convergence Laboratory and worked as a researcher in number of projects, including EU one. Her current research interests involve future Internet architectures, Information-Centric Networks, all-optical networks, and multilayer traffic engineering. After obtainig her PhD she now works for Sky

We thank BT Media and Broadcast for providing the venue and ample refreshments
We will be entering BT Tower by the main public entrance in Maple Sreet
We look forward to welcoming you to the BT Tower and would like to draw your attention to the following security arrangements.
On arrival at the BT Tower you will need to produce a form of official, photographic identification in addition to your invitation:
- New style driving licence
- Photo credit card
- Official company pass
- Student University Photocard
Business and Travel cards are not acceptable.
On arrival at BT Tower main entrance you will pass through an airport style security check.
Any items found which may be considered to constitute an offensive weapon, for example an article which has a blade or is sharply pointed, will be detained at the security point until you leave the building at the end of the event.
BT Tower lies between 4 tube stations about 8-15 mins walk away
Great Portland Street Circle, Hammersmith & City Metropolitan is the nearest - exit the station - head East along Euston Road one block to BBC Grafton House (which has strange Concrete finish) turn right down Cleveland Street until you come to the Clipstone St. / Maple St. junction – beware of traffic and cyclists from the right - Turn Left along Maple Street to the entrance just before the alley.
Warren Street Victoria and Northern Line exit the station into Tottenham Court Road walk south – take the Third Right into Maple Street walk against the direction of traffic to the Entrance which is just after an alleyway
Goodge Street Northern Line - turn left out of the station and walk North up Tottenham Court Road – Turn Third Left into Maple street and walk against the direction of traffic to the Entrance which is just after an alleyway
Oxford Circus Central Victoria and Bakerloo line Walk up Regent street , into the BBC open space – turn Right under the Peel wing to Langham Street which then becomes Foley Street - go to the end of the street and then turn Left into Cleveland Street at the Clipstone St. /Maple Street junction turn Right to the entrance just before the alley.
Tottenham Court Road Central Line Trains do not stop hence Northern Line only exit the station onto Oxford Street West/ South - walk along Oxford Street westwards turn second Right into Rathbone place (Soho St is its southern extension) at the top of Rathbone Place right and left into Charlotte Street to continue northwards until you meet Maple Street ( traffic and cyclits coming from the left) – turn left to the Entrance which is just after an alleyway
