Video coding

The image quality of videos has risen steadily in recent decades. But higher quality also means larger volumes of data to be transferred. There are various reasons for this, including changes in viewer expectations and habits as playback devices continue to improve. This puts rising pressure on both costs and time in the production of professional TV and film content, even as the number of media channels and platforms increases. Even VR headsets or industrial applications from machine vision to autonomous driving have real-time requirements that conventional video codecs frequently cannot meet.
To resolve this challenge efficiently − not only in terms of the available hardware but also with an eye to energy and resources − and above all in as close to real time as possible, a team of researchers headed by Siegfried Fössel, Joachim Keinert and Thomas Richter from the Fraunhofer Institute for Integrated Circuits IIS developed JPEG XS as a new ISO standard.
Innovative image compression format
The team of researchers has established JPEG XS as a state-of-the-art and forward-looking image compression format that transfers high-quality images in a production environment with minimal latency, low resource use and almost lossless image quality. In addition to its unique position as a technology for transmission of superior-quality images, it also offers huge economic advantages for studio technology and other fields, such as machine vision and self-driving vehicles.
The jury especially pointed out that the team of researchers “has developed a pioneering standard for resource-efficient real-time transmission of high-quality video data that has already been implemented in devices from various manufacturers.”
