About JPEG XS

JPEG XS (ISO/IEC 21122) is a new International Standard from the JPEG Committee (formally known as ISO/IEC JTC 1/SC 29/WG 1). It provides visually lossless image compression thanks to an interoperable low-latency lightweight coding system.

JPEG XS can be used as a mezzanine codec for any AV market. Beyond the JPEG XS Core Coding System, multiple profiles and formats have been defined allowing usage of this new codec for many applications, including, among others, the following:

  • Professional cameras 

  • Medical Imaging 

  • Video Surveillance and security 

  • Automotive Infotainment 

  • Set-top boxes 

  • Low-cost visual sensors in the IoT

  • Broadcast applications and live-production 

  • AV over IP

  • Digital Cinema applications 

  • Professional audio-visual systems 

  • Consumer TV 

  • Mobile video applications 

The JPEG XS lightweight codec enables higher resolution, frame rate, and bit depth. It also enables an increasing number of streams while safeguarding all of the advantages of an uncompressed stream, i.e. interoperability, visually lossless quality, low power consumption, low latency in coding and decoding, ease of implementation, the small size on-chip and fast software running on general-purpose CPUs.  

A simple, yet efficient, coding scheme allows latency and complexity to be kept very low while simultaneously achieving visually lossless quality at compression ratios up to 10:1. Quality evaluations show very good performance compared to other existing codecs, especially for multi-generation applications.
