This document specifies formats for redundant encoding and packaging of live segmented media (REaP).
This document specifies:
a) formats for Interchangeable Live Media Ingest and stream announcement;
b) format and segmentation strategy to generate interchangeable segments;
c) formats for generating interchangeable media presentation descriptions or playlists;
d) formats for efficient cloud storage access and archiving of live segmented media.
e) a protocol for communicating media descriptor files and fragmented media between encoders and packagers.
REaP enables the following:
1) failover support and rejoining of distributed components in the workflow (see Annex E);
2) workflows for live with dynamic ad insertion (DAI) with a decisioning system.
3) workflows with digital rights management (DRM) and content protection.
4) Mixing file and live inputs.
This document specifies additional constraint to formats defined in ISO/IEC 14496-12, ISO/IEC 23009-1, ISO/IEC 23000-19 and IETF RFC 8216.
