Together with content protection, complete DVB-H media player solutions and new audio coding technologies for surround and stereo audio, Fraunhofer IIS is one of the leading technology providers for tomorrow’s broadcasting world. To learn more about these exciting new technologies, visit our booth 8.380 and our slot at Mobile Zone M230.
Since “HD ready“ flat screen televisions are becoming more and more popular these days, broadcasters should be prepared for the rising demand for high-definition material. With the new MPEG-4 AVC real-time HD encoder software by Fraunhofer IIS broadcasters do not need special hardware for high quality compression of HD video. At the booth of Fraunhofer IIS, a whole broadcasting chain is going to be demonstrated: A portable hard disc recorder by Megacine sends 720p / 25 fps uncompressed high-definition video material to a high-performance Linux computer where the material is real-time encoded using MPEG-4 AVC at a data rate of 6 Mbps. Via IP connection the material is being sent to a regular work station PC which plays back the video.
Surround sound is a hot topic in the field of audio coding. MPEG Surround is a whole new audio coding scheme that allows a good 5.1 sound experience at bit rates so far used to compress stereo material – especially suitable for broadcasting. The surround extension is compatible with every current broadcast audio format and fully backward-compatible to stereo or mono receivers – thus, a soft transition from stereo to surround sound can easily be achieved.
A new audio format developed by Fraunhofer IIS in collaboration with I²R is High Definition Advanced Audio Coding (HD-AAC). By adding a fine-grain scalable lossless (SLS) layer to the AAC core broadcasters are able to distribute audio signals via bandwith-limited channels (with maximum data rates or maximum buffer sizes) with the highest quality of service.
With state-of-the-art implementations of the new Open Mobile Alliance standard OMA DRM 2.0, Fraunhofer IIS offers most efficient and user-friendly content protection for example for internet streaming or download applications.
A big topic at IBC 2006 is the world of mobile entertainment. In the field of DVB-H technology, Fraunhofer IIS demonstrates the new media player SDK for embedded Linux and Windows Mobile platforms supporting the latest standards of audio and video coding. MPEG-4 HE-AACv2 and MPEG-4 AVC (H.264) are integrated as well as real-time transport protocol (RTP) and MPEG-4 file (MP4) playback. All these components are also available individually for other embedded multimedia applications. At the IBC Mobile Zone, Fraunhofer IIS shows a complete broadcasting chain with several transmitted channels and playback on a handheld device.

A widely used diabetes medication combined with an antihypertensive drug specifically inhibits tumor growth – this was discovered by researchers from the University of Basel’s Biozentrum two years ago. In a follow-up study, recently published in “Cell Reports”, the scientists report that this drug cocktail induces cancer cell death by switching off their energy supply.
The widely used anti-diabetes drug metformin not only reduces blood sugar but also has an anti-cancer effect. However, the metformin dose commonly used in the...
A research team from the University of Zurich has developed a new drone that can retract its propeller arms in flight and make itself small to fit through narrow gaps and holes. This is particularly useful when searching for victims of natural disasters.
Inspecting a damaged building after an earthquake or during a fire is exactly the kind of job that human rescuers would like drones to do for them. A flying...
Over the last decade, there has been much excitement about the discovery, recognised by the Nobel Prize in Physics only two years ago, that there are two types...
What if a sensor sensing a thing could be part of the thing itself? Rice University engineers believe they have a two-dimensional solution to do just that.
Rice engineers led by materials scientists Pulickel Ajayan and Jun Lou have developed a method to make atom-flat sensors that seamlessly integrate with devices...
Scientists at the University of Stuttgart and the Karlsruhe Institute of Technology (KIT) succeed in important further development on the way to quantum Computers.
Quantum computers one day should be able to solve certain computing problems much faster than a classical computer. One of the most promising approaches is...
