HTTP Streaming over LTE using DASH

Fraunhofer HHI shows optimized LTE resource management for HTTP streaming video based on the MPEG DASH standard. This approach allows a cost-optimal use of LTE’s radio resources while maintaining the best possible video experience for each user. Web services are typically not under control of the network operator because they are run as web app over the top. However, HHI’s new cross-layer approach DASH over LTE allows optimization of web video services over wireless.

Full-HD Voice: Redefine mobile communication

HD content is everywhere today. However, mobile calls lack HD quality – they sound muffled and unnatural. Full-HD Voice enables phones to perform at the same level of clarity that we’ve come to expect in today’s HD world. This technology quadruples the audio spectrum of today’s regular phone calls and doubles the frequency of HD Voice calls at similar bit-rates, enabling new services. Telephone calls sound as clear as someone talking in the same room.

Spectrum and Infrastructure Sharing

Spectrum and Infrastructure Sharing have significant potential to increase the data rates in mobile networks further. Using a common infrastructure enables mobile operators to close their coverage holes in a complementary fashion, such as in rural areas. After each network is rolled out completely, infrastructure sharing doubles the density of base stations and the network capacity of each operator likewise. By sharing the spectrum, short-term fluctuations of the load in both networks can be mutually exploited (statistical multiplex). At Mobile World Congress 2012, Fraunhofer HHI demonstrates the basic technology of load- and channel-dependent spectrum sharing between two operators in a live demonstration over LTE.

awiloc® – Precise and seamless in- and outdoor positioning

awiloc® allows the positioning in inner cities and buildings based on existing Wireless LAN. The advantages of awiloc® are:

- Continuous positioning – multi-story buildings, underground facilities, complete cities
- Privacy-preserving positioning – position calculate on the mobile device
- Totally handset-based solution – no data communication, no central server
- Context aware – 3D models e.g. for floor identification, room identification
- Provider independent – collect your own reference base, set up exclusive services

The awiloc® technology can be licensed at Fraunhofer IIS. awiloc® is purely software-based and can easily be integrated into location bases services. The awiloc® MobileLocator software supports autonomous self localization on Android™, iOS™, Linux® and Windows® among others. Comprehensive tools and services for easy deployment are available. Some reference cases:

- Museum Guides
- Fair Guides
- City Guides
- Games
- Emergency Services
- Location Based Marketing
- Coupon Services

INCA – Intelligent camera

Designed for mobile usage in professional applications like Broadcast the new INCA camera provides advanced image processing, integrated compression and recording of high quality.
The camera is based on a 1GHz Dual-Core ARM CPU running the latest version of Android OS offering an open system for custom camera applications and image processing.

The system design is very compact and extremely modular with flexible front- and backends providing video output using HDMI, HD-SDI or Ethernet. Changing the cameras frontend creates whole new devices like an LTE relay or a high-quality video recorder.
This intelligent camera platform offers enough processing power to run complex algorithms directly on the embedded system, for example, the Fraunhofer IIS Shore™ Facefinder.


MPEG Surround provides high-quality surround sound for the new Japanese Mobile TV

The upcoming ISDB-Tmm/Tsb Multimedia Broadcast System for Mobile-TV, Video-on-Demand, Digital Radio and music services in Japan includes MPEG Surround for the delivery of surround sound. The ISO standard MPEG Surround delivers a convenient high-quality surround sound experience to the consumer. It is also cost-efficient for mobile operators and broadcasters since it only requires stereo bit-rates. MPEG Surround can be experienced on various types of receiving devices, including mobile handsets thanks to the built-in binaural surround decoder mode that allows for stunning surround sound using common stereo headphones. In addition, the surround programs can be enjoyed on any stereo receiver in excellent stereo quality making simulcasting obsolete.

Preview: Extended High Efficiency AAC – The world's most powerful audio codec

Extended HE-AAC is a new member of the AAC audio codec family. It provides significantly improved quality at low bit-rates between 16 and 64 kbit/s for both music and speech, ensuring compatibility with HE-AAC streams. Target applications include music streaming via wireless networks and satellite broadcasting systems.
