This session delves into the upcoming 3rd edition of JPEG XS, ISO/IEC 21122, which introduces the revolutionary TDC profile, enhancing compression efficiency while preserving the codec's hallmark features of low power consumption and microsecond latency. The TDC profile builds on the JPEG XS High profile by integrating wavelet-domain temporal differential coding, a technique that minimizes correlation between successive video frames, especially in static regions, without the need for motion compensation. This innovation ensures JPEG XS remains a leader in lightweight, low-latency, near-lossless compression. Ideal for graphics, e-sports, gaming, and complex desktop video sequences, TDC offers up to a 10 dB improvement in PSNR, while maintaining performance on high-motion content. Compatible with existing JPEG XS profiles and supporting all major platforms, TDC provides a seamless upgrade path for current systems. Attendees will gain insight into the technical advancements of TDC, its impact on media workflows, and how it upholds JPEG XS's reputation as the preferred mezzanine video codec for professional applications.
