RTP Payload Format for ISO/IEC 21122 (JPEG XS)
draft-ietf-payload-rtp-jpegxs-07
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.
