Multi-videoconference application of Telefónica I+D

For the Second Year Audit, Telefónica I+D prepared a demonstration regarding the Multi-videoconference application and its integration in the MUPBED network. The complete session was previously recorded with a video-camera at TID premises at Madrid, and then played locally at Brussels, during the WP2 and WP4 presentations. The whole demo consisted of three video contents:
  • Video 1 (WMV 45MB, 5:28min): In this video the integration activities are shown. The network agents and their functionalities are described, and also how they will interact in the different session phases. In the end, a Multi-videoconference session is set up, showing the different steps through the web-based management application.

  • Video 2 (WMV 20MB, 2:31min): Taking advantage of the session that was created in the first video, the preliminary version of the application is launched in this one. The different partners of the session are invited and presented one by one, including a person from TID Walqa, in Huesca (Aragon, Spain), around 400 km away from TID Madrid.

  • Video 3 (WMV 38MB, 4:33min): Some of the collaboration activities carried out between IST Projects MUSE2 and MUPBED are finally described in this video. Cristina Peña, from TID Walqa, who is involved in MUSE2, gives also her point of view regarding this collaborative work.

The tutorial was entitled "Real-Time Behaviour of Data Networks for Audio and Video Transmissions" and attracted well over 100 people from all major German television channels and manufacturers of network application equipment. Highlights were presentations of Hans-Martin Foisel of MUPBED partner T-Systems as well as presentations of Ralf Kleineisel and Jochen Reinwand (DFN) of the GÉANT2-Project / JRA1.

MUPBED strongly represented at this year's ECOC (European Conference on Optical Communication)

Conference program and contributions
This year's ECOC conference attracted some 1200 attendees and is one of the largest events world-wide in the area of optical communication. The IST project MUPBED was strongly represented with various activities.
  • A regular paper submission by MUPBED authors was accepted as a poster paper: A group of authors from Deutsche Telekom, Telecom Italia, Ericsson, and Marconi contributed with the paper "Interworking achievements in a pan-European ASON/GMPLS multi-domain and multi-layer test network". This paper provides information on interworking issues occurring if today's ASON/GMPLS solutions are applied to a multi-domain network scenario, which will be the standard scenario for any big carrier's network as well as for research networks.
  • MUPBED gave an invited paper in the workshop "GMPLS/ASON Implementation in Field Trials and Carrier Networks". The paper was given by Jan Späth (Ericsson). The contribution describes on-demand services in a European scale ASON/GMPLS multi-domain and multi-layer test network, and covers both theoretical concepts as well as a practical field-trial implementation of leading edge control plane technologies.

  • MUPBED was also present at the exhibition which was running in parallel to the scientific ECOC conference program. MUPBED was presented on the IST booth with a poster, a number of control plane demonstrations and a joint presentation with GN2/JRA3.

MUPBED at the TERENA Networking Conference (TNC 2006), Catania, Italy, May 15-18, 2006

MUPBED presented several demonstrations at the TERENA Networking Conference 2006: Visitors to the booth had the opportunity to view all of the five local MUPBED testbeds and the studio equipment of a typical scenario of a future research application in the area of tele-medicine or video productions. Visitors could also follow MUPBED traffic statistics which was especially interesting, since the demonstrations also included the live transmission of uncompressed video over a distance of more than 3000 kilometers from the Friedrich - Alexander University of Erlangen-Nuremberg to Catania. On its way to Sicily, the video payload of over 300 Megabit/s traveled across an LSP in X-WiN (DFN) to Berlin (T-Systems), across GÉANT2 and GARR infrastructures to Torino (Telecom Italia) and finally to the conference center in Catania. Among the many visitors of the live demonstrations was also Mario Campolargo, head of the unit for Research Infrastructure in the Directorate-General "Information Society and Media" of the European Commission.
In addition to the live demonstrations at the MUPBED booth, an overview of the project with the latest project accomplishments was also provided in a presentation (pdf) by Jan Späth (project co-ordinator/Ericsson).

MUPBED at the Internationale Funkausstellung (IFA 2005), Berlin, Germany, Sept. 2-7, 2005

The Friedrich-Alexander University of Erlangen-Nuremberg (FAU) presented the MUPBED project at the Internationale Funkausstellung (IFA) in Berlin, September 2-7, 2005 with a demonstration of their MUPBED application scenario. The setup was very extensive and elaborate and included the showing of a world premiere: As an absolute technical novelty for MUPBED, the FAU demonstrated slightly compressed HD-transmissions using 800 Megabit/s of bandwidth for Gigabit Ethernet interfaces. The FAU also demonstrated completely uncompressed HD video transmissions using 1.5 Gigabit/s of bandwidth for SDH network infrastructures. Both codecs and adapters were provided by Media Links (www.medialinks-systems.com) and in the case of the slightly compressed codecs were made available by the company through a direct import from Japan on the night before the exposition started.

The motivation for attending the exposition was based on several reasons: At the expo it was possible to actually show the FAU MUPBED application scenario, since the highly technical and complex application required a partner with the necessary support and expo infrastructure. The FAU partner at the IFA was the Institut fuer Rundfunktechnik (IRT) who also provided the booth and access platform for the demonstration. One major motivation was also to meet and have access to leadership representatives of related user communities and to gain access to science and research communities at the Forum for Science and Technology (TWF) where the demonstration booth was located.

Since the application of the FAU is intended for research applications in tele-medicine / learning and video productions for research channels, the FAU used scientific learning materials as video source materials and transmitted the live presentations from the Forum for Science and Technology (TWF) to the booth. The HDTV-camera was remote controlled from the booth across the connection (see Foto 3). Additional source material was also available from an HD-video server for exposition periods when no TWF presentations were scheduled. The FAU in cooperation with the IRT also showed a cyclic Power Point presentation at the booth which explained the project MUPBED and the FAU application scenario. Additional handout material on the MUPBED project and FAU application had also been prepared and was available at the booth in both German and English. A press release was prepared and issued concerning the world premiere of slightly compressed HD-transmissions.

The setup of the booth and adjacent booths allowed a direct comparison of HD-video quality with lower quality MPEG-2 video at 8 Megabit/s and MPEG-4 (H.264) video at 12.5 Megabit/s. The demonstration showed that this type of application is up and running, demanding and highly interesting. The exposition offered the possibility to have intensive discussions on latency, video quality, transmission rates and Quality of Service (QoS) with

  • Research institutes
  • Universities
  • Commissions and small companies
  • Network providers
  • Most major TV companies.

The demonstration provided the opportunity to show and explain the differences between high resolution uncompressed video transmissions of MUPBED and video streaming applications in general: The scientific user groups of the FAU application scenario within MUPBED are

  • Tele-medicine for second opinion diagnosis, interactive teaching, …
  • Synchronous tele-teaching
  • (Scientific) interactive distributed TV video productions
    • with requirements as in the case of Tele-medicine of
    • "best" picture quality (color, resolution, no artefacts, no missing details)
    • low latency (for surgery, quality assurance) (should stay well below 150 ms one-way according to ITU-T recommendation G.114; MPEG-2 compressions require at least 180 ms for a one-way encoding-decoding process; this is based on I-frame only compression with low quality; the MPEG compression algorithm with predictive elements and required reference buffering prevents further time delay improvements.)

Both loss of quality and low latency problem can be avoided by using uncompressed transmissions. The user and research communities demonstrated a clear need for such transmissions across ATM networks; since ATM infrastructures are no longer available, the research communities look to MUPBED and its ASON/GMPLS structures to provide the required network QoS for their applications.
