This standard is part of a suite documenting carriage constraints of Next Generation Audio (NGA) codecs in MPEG-2 transport systems and in MPEG DASH. This part of the standard, in conjunction with Part 1 , defines carriage of MPEG‑H Audio in MPEG‑2 transport systems and in MPEG DASH.
The descriptors necessary to signal MPEG‑H Audio in MPEG-2 transport systems are defined in ISO/IEC 13818‑1  and ETSI EN 300 468 , and their usage is described in this document.
Multiplexing and transport for cable using MPEG-2 systems are defined in SCTE 54 . Coding constraints for MPEG‑H Audio elementary streams are defined in SCTE 242-3 2017 .
