MOQT Streaming Format (MSF) is a media format designed to deliver LOC [LOC] compliant media content over Media Over QUIC Transport (MOQT) [MoQTransport]. MSF works by fragmenting the bitstream into objects that can be independently transmitted. MSF leverages a catalog format to describe the output of the original publisher. MSF specifies how content should be packaged and signaled, defines how the catalog communicates the content, specifies prioritization strategies for real-time and workflows for beginning and terminating broadcasts. MSF also details how end-subscribers may perform adaptive bitrate switching. MSF is targeted at real-time and interactive levels of live latency, as well as VOD content.
This document describes version 1 of the streaming format.
