Low-latency JPEG XS format is optimized for live streaming and VR

The new standard was introduced this week by the Joint Photographic Experts Group, which says that the aim of JPEG XS is to “stream the files instead of storing them in smartphones or other devices with limited memory.” So in addition to getting faster HD content on your large displays, the group also sees JPEG XS as a valuable format for faster stereoscopic VR streaming plus videos streamed by drones and self-driving cars.

“We are compressing less in order to better preserve quality, and we are making the process faster while using less energy,” says JPEG leader Touradj Ebrahimi in a statement. According to Ebrahimi, the JPEG XS video compression will be less severe than with JPEG photos — while JPEG photos are compressed by a factor of 10, JPEG XS is compressed by a factor of 6. The group promises a “visual lossless” quality to the images of JPEG XS.

JPEG XS is open source, has a universal HDR coding format, which also lends itself well to professional video transcoding. The format is still awaiting approval, but JPEG XS will likely be used in movie editing, space imagery (the European Space Agency has already expressed interest for using it to transmit video from space probes) and professional cameras.

Consumer electronics like “self-driving cars, virtual reality, augmented reality, and wireless connections between multimedia devices and TV monitors or projectors” will be next, according to Ebrahimi.
