Modern data channels allow us to easily send HD video, music and photos several megapixels in size– it takes no more than a few minutes for all kinds of files to make it onto the web or our hard drives. Fraunhofer researchers are working on modern processing and compression methods to achieve even greater quality while reducing file size even further.
The number of cameras in cars is increasing. However, through the flood of data the internal networks are being pushed to their limits. Special compression methods reduce the amount of video data, but exhibit a high degree of latency for coding. Fraunhofer researchers have adapted video compression in such a way that a latency is almost no longer perceivable. It is therefore of interest for use in road traffic or for autonomous driving.
High Efficiency Video Coding (HEVC oder H.265 oder MPEG-H) ist eine gemeinsame Entwicklung der ISO/IEC Moving Picture Experts Group (MPEG) und der ITU-T Video Coding Experts Group (VCEG). Es soll im Vergleich zur Standardkompressionsmethode H.264 eine doppelt so starke Kompression bei subjektiv gleichbleibender Videoqualität erzielen. Die Technologie wird demnächst von der ISO/IEC bestätigt.
The EVS codec transmits speech of such pure quality that it sounds as if the person you’re calling is in the same room.

Smartphones can do almost everything you want, but their poor voice quality is still a vexing issue. Fraunhofer researchers have helped develop a new codec to banish this problem. Their solution raises voice quality to an unprecedented level – making it sound as natural as if the person you’re calling is standing right next to you. That’s because, for the first time, the entire audible frequency spectrum is transmitted.
MP3 (MPEG Layer 3) is an audio format that encodes and stores music without audible loss. Since the process also saves space, it allows files to be transferred quickly. MP3 has grown beyond the German market to become a world standard, serving as a calling card for German innovation and having gained a broad cultural and financial significance. In July 2008, the Fraunhofer-Gesellschaft and Friedrich-Alexander-Universität Erlangen-Nürnberg together founded the International Audio Laboratories Erlangen research center. Funded by income generated from MP3 patents, the center carries out further research into audio and multimedia technologies.
