Abstract

---

Image sequences have been transmitted and stored in uncompressed form in many cases, such as in professional video links (3G/6G/12G-SDI), IP transport (SMPTE2022 5/6 & proprietary uncompressed RTPs), Ethernet transport (IEEE/AVB), and memory buffers. JPEG-XS standardization subgroup is developing a low-latency lightweight image coding system allowing an increased resolution and frame rate, while offering visually lossless quality with reduced amount of resources such as power and bandwidth at a reasonable level. The upcoming JPEG XS standard will offer a low-latency lightweight image coding system that is able to support increasing resolution (such as 8K) and frame rate in a cost effective manner. We will show the main principle behind the reference model of JPEG-XS and the current performances. It is based on a low-latency wavelet transform and efficient ad-hoc entropy coding. Current developments are aiming to issue a standard for the early 2018.
