Dem japanischen Anbieter von Telekommunikationsgeräten, OKI Electric Industry, ist es gelungen Ultra HD-Material via IPTV von Japan über Singapur zu den Phillipinen zu übertragen. Dabei wurde das Internet Protokoll IPv6 genutzt, welches heute das standardisierte Verfahren zur Übertragung von Daten ist.
Dieser Versuch sollte auch verdeutlichen wozu das IPv6 Protokoll fähig ist, da dieses in keinem der Märkte großen Anklang findet.
Das Ultra HD-Material, welches von Hokkaido Television Broadcasting zur Verfügung gestellt wurde, ist auf einen MediaServer von OKI gespeichert worden und von dort via Lightweight Interactive Multimedia Enviroment (LIME) über IPTV übertragen worden. Die Übertragung war Teil der Video-Übertragungs-Studie im Rahmen des Sapporo Snow Festivals Anfang Februar.
Japanische Hersteller, haben es mit Unterstützung der Regierung, an die Spitze der Entwicklung und Vermarktung des neuen 4K Ultra HD-Standards geschafft. Da 4K die benötigte Datenmenge quasi vervierfacht, gab es immer wieder Bedenken, dass heutige Übertragungsmethoden diesen Ansturm an Daten einfach nicht gewachsen seien – deshalb entschied man sich für die Übertragung via IPv6.
OKI betonte in der Pressemitteilung, dass der Media Server nur mit üblichen Video-Übertragungs-Funktionen ausgestattet und via installierten IPTV Server trotzdem in der Lage war, das hochauflösende Material zu übertragen. Diese Botschaft war OKI sehr wichtig, da es noch keine einheitlichen Standards für die Übertragung von 4K gibt. Im Grunde ist es aber bereits mit den vorhandenen Mitteln möglich, Ultra HD-Material zu übertragen.

– Other trials verify state-of-the art IPTV technologies to promote ITU-T IPTV Standards –
TOKYO —
OKI (TOKYO:6703) recently concluded successful trials based on the OKI MediaServer video distribution system as part of efforts to promote ITU-T IPTV Standards. These trials involved the distribution of IPv6-based video to Singapore and Philippines, regions where IPv6 has yet to be adopted; the distribution of 4K video content based on state-of-the-art IPTV technologies; and feasibility confirmation for new IPTV applications allowing collaborative linking to services available on the Internet.
The trials were performed using the ITU IPTV IPv6 Global Testbed („testbed“ hereafter), an experimental environment that uses OKI MediaServer to distribute content created by Hokkaido Television Broadcasting (HTB) based on the Lightweight Interactive Multimedia Environment (LIME) standard. Previous trials distributed video content to the ITU-T Headquarters in Switzerland and to Dubai in the United Arab Emirates. The latest trials distributed video to Singapore and the Philippines, regions that have yet to fully adopt IPv6. The trials took place over the three-day period from February 5 to 7, 2013, as part of the Sapporo Snow Festival Video Distribution Trial hosted by the National Institute of Information and Communications Technology (NICT, President: Dr. Hideo Miyahara).
Malcolm Johnson, Director of the Telecommunication Standardization Bureau, ITU: „ITU emphasizes the mainstreaming of accessibility considerations in the development of international standards (ITU-T Recommendations). This is especially important in the case of audiovisual media and ITU’s work on IPTV is an example of how accessible ICTs will reduce the impact of disability and increase social inclusion. Globally defined standards for IPTV by ITU-T Study Group 16 are key for interoperable, high quality, accessible content distribution over quality-managed networks.“
Andrea Saks, convener of the JCA-AHF, a key group on accessibility in ITU: „Audiovisual media accessibility is key to enabling the integration of persons with disabilities into society – especially today when new technologies bring so many opportunities. ITU’s standards process ensures that accessibility needs are met from the very beginning, as well the needs of the global multi lingual mainstream society – therefore avoiding costly retrofitting at a later date. The use of subtitling (or captioning as it is also known) in the experiment proves that captioning is not just for persons with disabilities, but for everyone.“
Cesar Pineda: Engineer, Associate Faculty Electronics, Computer and Communications Engineering (ECCE) Department. Ateneo de Manila University: „With the IPTV Testbed, our Ateneo de Manila University senior engineering students were able to do hands-on study and experiments on new TV network architecture, content creation and video distribution using OKI Mediaserver integrated platform for high quality video distribution over PLDT’s IP network The cooperation proves also that to develop a new integrative technology, an efficient industry- academe government collaboration helps accumulate knowledge, accelerate standardization/development of new technology and incubate business solution. We therefore thank the ATENEO-PLDT-NTT-OKI-ITU-ICTO international collaboration that happened.“
