JPEG XS

The JPEG XS (ISO/IEC 21122) standard is a lightweight low latency image and video compression algorithm (codec) that maintains visually transparent compression.[1][2][3][4][5] Applications of the standard include streaming high quality content for virtual reality, drones, autonomous vehicles using cameras, gaming, and broadcasting.[2][6][7][8]

In an attempt to address these and other new uses, the JPEG committee in 2016 started standardization with an open call for a high-performance, low complexity image coding standard. The best performing candidates, namely codecs from the Belgian company intoPIX and Fraunhofer IIS, formed the basis for the new standard. First implementations were demonstrated in April 2018 at the NAB Show and later that year at the International Broadcasting Convention.[9]

An advantage of the format is that it requires less CPU processing than most other codecs. Another advantage is that it is highly parallel, thus well suited for multi-core CPU as well as GPU implementations. The standard has an end-to-end latency not larger than 32 image lines, which was formulated as a requirement during its development.[10]

Fraunhofer claims transparent compression at ratios of up to 10:1. The maximum supported resolution is 8K, and the maximum supported frame rate is 120 fps.[1]
