JPEG Initiates Standardization of
Low-latency Lightweight Coding System – JPEG XS
JPEG XS — Today’s industrial applications often imply transport and storage of uncompressed images
and video. This is for instance the case in video links (SMPTE Serial Digital Interface), IP transport
(SMPTE 2022 5/6 & proprietary uncompressed RTPs), Ethernet transport (IEEE/AVB), proprietary
transports, memory buffers, and omnidirectional video capture and rendering. In this context, the JPEG
Committee has started a new standardization project, JPEG XS, referenced as ISO/IEC 21122, that
targets a low-latency lightweight coding system aimed at supporting higher resolutions and frame rates
over these channels while assuring high visual quality and keeping power and bandwidth consumption
within a reasonable budget. This effort should result in a highly interoperable solution.
A public workshop on JPEG XS was organised at the JPEG meeting in La Jolla on February 23, 2016.
The proceedings of this workshop are published on the JPEG website at www.jpeg.org.
The JPEG Committee released a Call for Proposals that invites candidate coding technologies. Interested
coding experts and codec providers are encouraged to participate in this standardization activity and
submit proposals. The deadline for an expression of interest and submissions of proposals has been set
to May 23rd, 2016, as detailed in the Call for Proposals. The call for proposals, as well as the
proceedings of the JPEG XS workshop, organized during the 71st WG1 meeting in La Jolla (US), are
publicly available on the committee website.
JPEG XT — ISO/IEC 18477-6 and ISO/IEC 18477-7, JPEG XT parts 6 and 7 have been published as
international standards. Part 6 of JPEG XT allows to extend the bitdepths of JPEG images from 9 to 16
bits, modernizing the well-known JPEG format to satisfy the needs of the 21st century.
JPEG XT part 7 allows to extend the dynamic range of images even further by allowing floating point
samples; a typical application for JPEG XT part 7 is high-dynamic range photography. JPEG XT part 7

71st Meeting – La Jolla, CA, USA – 22-26 February 2016
improves the compression factor over existing solutions by a factor of three to four without any visible loss
of image quality.
As for all of JPEG XT, parts 6 and 7 ensure compatibility to existing JPEG applications, all JPEG XT
images - regardless of their dynamic range - can be decoded and viewed by any JPEG decoder.
Reference implementations for JPEG XT are ready for download in source code form at www.jpeg.org.
Two additional parts - for lossless image compression and coding of alpha channels - are currently under
preparation by the ISO committee and are expected to be available as international standards in July
2016.
JPEG Privacy & Security — A second public workshop on JPEG Privacy & Security was organised at
the JPEG meeting in La Jolla on February 23, 2016. The proceedings of this workshop are published on
the JPEG website at www.jpeg.org. The JPEG committee continues investigating solutions that will
empower end-users to protect their privacy when sharing JPEG files or to allow professional and cultural
heritage archives to signal for example ownership rights. JPEG will kick-off the standardization process
for JPEG Privacy & Security later this year.
“Enabling seamless interoperability for exchange of image data within and across applications has been
the main objective of JPEG committee. JPEG XS breaks new grounds in this direction by providing a
large number of existing and emerging imaging application, efficient and interoperable solutions in
environments where lightweight and low-latency are among top requirements.” said Prof. Touradj
Ebrahimi, the Convener of the JPEG committee.
About JPEG
The Joint Photographic Experts Group (JPEG) is a Working Group of ISO/IEC, the International
Organisation for Standardization / International Electrotechnical Commission, (ISO/IEC JTC 1/SC
29/WG 1) and of the International Telecommunication Union (ITU-T SG16), responsible for the popular
JBIG, JPEG, JPEG 2000, JPEG XR, JPSearch and more recently, the JPEG XT, JPEG XS and JPEG
Systems families of imaging standards.
st
The WG1 group meets nominally three times a year, in Europe, North America and Asia. The latest 71
meeting was held on February 22-26, 2016 in La Jolla, CA, USA and was hosted by INCITS L3. The next
nd
(72 ) WG 1 Meeting will be held on May 30-June 3, 2016, in Geneva, Switzerland.
More information about JPEG and its work is available at www.jpeg.org or by contacting Peter Schelkens
and Fumitaka Ono of the JPEG PR Subgroup at pr@jpeg.org.
