Redundant Encoding and Packaging for Segmented Live Media

ABSTRACT

We present the MPEG standardization activity on redundant encoding and packaging for live segmented media. The standardization includes profiling the Dynamic Adaptive Streaming over HTTP (DASH) Media Presentation Description for ingest, storage and redundant packaging applications. Further, a Common Media Application Format (CMAF) segment and track format is defined to support redundant encoding and packaging using a common timeline relative to the Unix epoch. The standardization is still ongoing and we solicit feedback from academic and industry practitioners.
