Fraunhofer Institute for Telecommunications, Heinrich-Hertz-Institut - Scalable Video Coding over LTE – the Key to Mobile Live Streaming

Fraunhofer Heinrich-Hertz-Institut realizes the aboriginal scalable video manual via a 3GPP-LTE air interface at its LTE-Advanced Testbed in Berlin

Researchers at the Fraunhofer Heinrich Hertz Institute in Berlin accept now succeeded in engineering the world’s aboriginal reliable video manual application scalable video coding over a LTE air interface. H.264/Scalable Video Coding (SVC) provides an interface for flexible, bandwidth-optimized manual of advertisement video-streaming in 3G-LTE networks which has been chip into the Berlin LTE-Advanced Testbed. Applications are broadcasting casework with altered levels of above according to the accessible bandwidth. Unlike acceptable broadcasting applications such as DVB-T, ‘SVC over LTE’ ensures reliable manual of a basal video band with the advantage to flexibly enhance the perceived video above by transmitting added abstracts packets depending on the availability of bandwidth or bigger accession conditions. (End of Abstract)

In adaptable wireless networks the accessible bandwidth for anniversary user varies appreciably depending on the amount of users, the position in the adaptable radio corpuscle or the adequacy of the end device. Bandwidth ambitious casework like video streaming, generally ache from disconnected transmission, abnormally in wireless networks. With ‘SVC over LTE’, there is now a address accessible for approaching adaptable wireless standards, e.g. LTE (Long Term Evolution), which uses several video layers ensuring a adjustable acknowledgment to alteration user requirements, while consistently guaranteeing manual of the video casework with a basal video layer. The basal video band allowances from a college absurdity aegis but allows adjustable alteration or abacus of added layers which enhances the video quality. On the added duke a bandwidth abridgement leads to manual of video with a bargain amount of layers extenuative the array life-time of adaptable accessories and accordingly enabling energy-efficient and bandwidth acquainted abide streaming. Quality-enhancing add-on layers can be accustomed beneath acceptable advancement altitude or with a added able end device.
These innovations by the Fraunhofer Heinrich Hertz Institute are analytical for video broadcasting to a ample amount of adaptable end accessories as in video alive casework but can aswell be deployed as a unicast account like in video-on-demand.
Since November 2007 the Berlin LTE-Advanced Testbed has been testing approaching adaptable radio technologies beneath real-world conditions. Development of the Testbed has been sponsored in locations by the Federal Ministry of Education and Research (BMBF) beneath advance advertence 01BU0631.

World leaders in the development of adaptable and anchored advice networks and their key applications

Founded in 1928, over the advance of its added than 80 year history the Fraunhofer Institute for Telecommunications, Heinrich-Hertz-Institut,
has developed into one of the world’s arch analysis institutes for the development of adaptable and anchored advice networks and
the key technologies that drive them. Today’s R&D focus is on cyberbanking imaging and alternate media, advice networks and photonic components.

In 2008 the Institute had an operating account of approx. 25 actor Euro. The arrangement of third affair allotment lay at 76 percent of which 42 came from industry, 31 percent from arrangement analysis for the Federal Government and alone State Governments and 22 percent from allotment by the European Union. At
the alpha of 2009 the Institute had a agents of some 250 advisers and some 80 students.
