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