Next Generation Audio Carriage Constraints for Cable Systems: Part 4 – DTS-UHD Audio Carriage Constraints

Executive Summary

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. It is intended to be used in conjunction with the specific audio technologies described in subsequent Parts of this standard (see [SCTE 243-1]).

Scope

This document is part four of a multi-part standard that specifies carriage constraints of Next Generation Audio (NGA) codecs in MPEG-2 Transport Stream and in MPEG ISO-BMFF media segments. In conjunction with [SCTE 243-1] this document defines the carriage of DTS-UHD audio in MPEG-2 Transport Stream and MPEG DASH using ISO BMFF media segments.

Benefits

The Next Generation Audio (NGA) system audio system provides immersive and personalizable sound for television.

Note that NGA is not compatible with the audio system used in [SCTE 54]-era service.
