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.
