Communication and Knowledge – Audiovisual signal processing

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.

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.

H.265 high efficiency video coding (HEVC)

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.
