             RTP Payload Format for ISO/IEC 21122 (JPEG XS)
                    draft-ietf-payload-rtp-jpegxs-04

Abstract

   This document specifies a Real-Time Transport Protocol (RTP) payload
   format to be used for transporting JPEG XS (ISO/IEC 21122) encoded
   video.  JPEG XS is a low-latency, lightweight image coding system.
   Compared to an uncompressed video use case, it allows higher
   resolutions and frame rates, while offering visually lossless
   quality, reduced power consumption, and end-to-end latency confined
   to a fraction of a frame.
