With its unique personalization features, the MPEG-H Audio system offers fully user-adjustable dialogue level and customizable audio description that are under full control of the content provider, allowing the media consumption experience to be tailored to individual preferences and needs.

Next-generation open audio standard

The system is based on the MPEG-H 3D Audio standard from ISO/IEC MPEG, the international standards group responsible for many globally dominant media standards such as MP3, AAC, MPEG-1, MPEG-2, MPEG-4, AVC/H.264 and HEVC/H.265. The MPEG-H Audio system is included in the ATSC, DVB, TTA (Korean TV) and SBTVD (Brazilian TV) TV standards.
It is used as the sole audio system in the world’s first terrestrial UHD TV service in South Korea. Launch of the system under the ATSC 3.0 standard was in May 2017. In Brazil, it is used to enhance terrestrial HD TV services with personalized and immersive sound. The first MPEG-H Audio broadcast over ISDB-Tb (SBTVD TV 2.5) took place in September 2019 and since November 2021, MPEG-H has been used in regular broadcast. It has also been selected as the sole mandatory audio system for Brazil’s next-generation TV 3.0 broadcast service that is expected to start in 2024 and for a new broadcast standard to be launched in China.

Ease of use

The MPEG-H Audio System is designed to work with today’s well-established streaming and broadcast workflows. Immersive sound can be played back over TV sets, loudspeakers, headphones, or MPEG-H equipped soundbars.
