JPEG XS (ISO/IEC 21122) is a direct replacement for uncompressed video workflows and introduces significant network bandwidth and media processing savings to production facilities and wide-area networks (WANs). This contemporary and widely-implemented video codec achieves visually lossless image quality at microsecond-level latency. JPEG XS scales effortlessly for SDI or IP format video and is an obvious choice for HD, UHD-4K and UHD-8K content production over the wide-area network. An efficient power and processing footprint makes further makes JPEG XS highly suited for bandwidth-efficient campus and facility networks (LANs).
The suite of standardization work around JPEG XS, in particular VSF TR-07, is of particular importance when there is a lack of control over PTP time accuracy. The combination of JPEG XS and VSF TR-07 allows for production networks to effortlessly extend over the WAN without PTP Time Error performance.
As JPEG XS processing can be implemented in general purpose compute, i.e. CPU as well as special purpose compute such as GPU and FPGA, there is already an established ecosystem of scalable JPEG XS processing applications with ready-made essence, composite and aggregate standard exchange formats, i.e. VSF TR-08, TR-07 and TR-09 respectively.
The ability of JPEG XS to operate and be exchanged across LAN, WAN and Cloud, whether that is PTP-timed or Transport Streams adapted makes it a breakthrough in flexibility for video compression standards. This orchestration or new technologies and operational insights is fundamental to efficiently delivering video with no delay or quality compromise. In essence, JPEG XS allows production networks and remotely produced events to do ten times more with existing resources.
