Abstract

JPEG XS is a lightweight, low-latency image coding standard developed for transmission of video streams over IP. The third edition of JPEG XS, currently under development of ISO, adds a frame buffer and temporal predictive coding in the wavelet domain to improve its coding efficiency on screen content and thus improves JPEG XS for remote desktop applications. Due to bandwidth constraints, the frame buffer itself needs to be compressed, and thus the frame buffer bandwidth needs to be considered for interoperability between implementations. This paper reports on core experiments conducted in JPEG (ISO/IEC SC29 WG1) to design profiles and levels for the third edition, and how WG1 is currently considering profiling the screen content coding extensions of JPEG XS.
