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

Executive Summary

This document is part of a suite documenting coding constraints of Next Generation Audio (NGA) systems for cable television. It is intended to be used in conjunction with the specific audio technologies described in subsequent parts of this standard (see [SCTE 242-1]).


This document is part four of a multi-part standard that specifies the coding constraints of Next Generation Audio system for cable television. In conjunction with [SCTE 242-1], this document defines the coding constraints on DTS-UHD for cable television. The carriage of the streams described in this specification is defined in [SCTE 243-4] in conjunction with [SCTE 243-1].


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