Multi-generation-robust Coding with JPEG XS

The JPEG committee (formally, ISO SC29 WG1) is currently standardizing a lightweight mezzanine codec for video over IP transport under the name JPEG XS. A particular challenging design constraint of this codec is multi-generation robustness, that is the necessity to minimize the error built-up under multiple re-compression cycles. In this paper, we discuss the sources of such errors, how they are avoided in the JPEG XS design and compare the multi-generation robustness of JPEG XS with that of other codecs.
