Overview
ETSI TS 103 973 defines the Coded Multisource Media Format (CMMF), a container format for carrying coded media from more than one network source at once. See CMMF in the Technical Analysis for how it works.
3GPP SA4 references CMMF as part of the Release 19 Advanced Media Delivery study (TR 26.804); see Standards: 5G Media Streaming (5GMS) and Advanced Media Delivery for that context. 5G-MAG tracks CMMF itself as a repository of Content Delivery Protocols, alongside FLUTE and ROUTE, rather than as a separate project. For the version history behind this specification, see Standards Evolution.
