Those who have been using computers for a few years now, know about JPEG, which is a standard format for digital image compression. Now, the group behind JPG is all set to release JPEG XS that will focus on VR (Virtual Reality), AR (Augmented Reality), drones, and self-driving cars. Usually, when a new format is introduced, the older format is discontinued. But in this case, both the old and new formats are likely to be used side-by-side.

While JPEG was created to download digital images, the new JPEG XS has been specifically created for streaming video and VR. With low-latency streaming capabilities, the group expects that the new standard will help tackle motion sickness. The files encoded in the new standard won’t be smaller in size, as many of you may expect. Also, JPEG XS will be more energy efficient compared to JPEG, but there is no word on how exactly this works.

The team behind the new JPEG XS format is headed by Touradj Ebrahimi, a professor in EPFL’s School of Engineering (STI). “For the first time in the history of image coding, we are compressing less in order to better preserve quality, and we are making the process faster while using less energy. We want to be smarter in how we do things. The idea is to use less resources, and use them more wisely. This is a real paradigm shift,” he said.

Despite the fact that compressed files will be of a larger size, streaming them over Wi-Fi and upcoming 5G networks shouldn’t be an issue. The end goal behind creating JPEG XS is to have files that are easier to stream, rather than storing them locally on a device or a smartphone.
