Group Behind JPEG Unveils New ‘visually lossless’ Compression Standard for VR/AR and More

652x367This week at NAB Show in Las Vegas, the Joint Photographic Experts Group (JPEG), the international committee behind the titular image compression standard, unveiled JPEG XS, a new format that is touted as a lower energy compression solution that provides higher quality images at low latency over broadband networks such as 5G.

Considering the current state of livestreaming VR video, including 360 & 180-degree video and the burgeoning field of light field-based captures, a new compression standard could mean higher resolutions and frame rates, making better quality streaming VR video a real possibility. 5G networks, which in recent tests have provided users 442 Mbps download speeds, are poised to address some of the underlying issues of streaming VR video quality, but compression, the JPEG XS creators say, is key.

Fraunhofer IIS, one of the co-developers behind JPEX XS, says the new ISO mezzanine codec standard offers “visually lossless quality.” The new standard supports to 8K and features a frame rate from 24 to 120fps. Compression ratios range up to 6:1.

“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,” says working group head Professor Touradj Ebrahimi in a prepared statement. “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.”

While JPEX XS looks to supplant JPEG, it isn’t going to do so overnight...
