This document standardizes the MPEG-H Audio system for use in the ATSC 3.0 Digital Television System. It describes the characteristics of the MPEG-H Audio system and establishes a set of constraints on MPEG-H Audio for use within ATSC 3.0 broadcast emissions. The ATSC 3.0 audio system provides an enhanced feature set and improves upon the capabilities of past ATSC audio systems. The system provides listeners with both a personalized and an immersive experience. The ATSC 3.0 audio system establishes a common framework for multiple Next Generation Audio (NGA) systems, both current and future. The MPEG-H Audio system is one of the NGA systems standardized in ATSC 3.0.
