Anotation

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.
