ABSTRACT

We present the MPEG standardization activity on redundant encod- ing 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 Ap- plication Format (CMAF) segment and track format is defined to support redundant encoding and packaging using a common time- line relative to the Unix epoch. The standardization is still ongoing and we solicit feedback from academic and industry practitioners.
