Next Generation Audio Carriage Constraints for Cable Systems: Part 1 – Common Transport Signaling

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 243-2], [SCTE 243-3], and [SCTE 243-4]).

Scope

This document specifies the common framework for 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.

The common descriptors necessary to signal NGA in MPEG-2 transport systems are defined in [ISO 13818-1] and ETSI [EN 300-468], and their usage is described in this Part of the standard. Additional codec specific descriptors are defined in subsequent Parts (which defines codec specific carriage constraints: . see ([SCTE 243-2], [SCTE 243-3], and [SCTE 243-4]).

Multiplexing and transport for cable using MPEG-2 transport systems are defined in [SCTE 54] . This standard provides a general description of NGA systems) and subsequent Parts of the standard define codec specific carriage constraints) (see [SCTE 243-2], [SCTE 243-3], and [SCTE 243-4]).

Benefits

The Next Generation Audio (NGA) system audio system provides immersive and personalizable sound for television. It is not compatible with the audio system used in [SCTE 54] -era service.
