A world first at NAB 2019: ATSC 3.0 hybrid delivery with MPEG-H Audio

Fraunhofer IIS and ATEME, in collaboration with S&T and UniSoft, demonstrate a complete ATSC 3.0 broadcast chain and its advanced hybrid delivery features using MPEG-H Audio at the Fraunhofer IIS NAB Show booth (SU4816).

Fraunhofer IIS and French supplier of video delivery infrastructure ATEME worked closely together to integrate the multistream capabilities of MPEG-H Audio into ATEME’s TITAN Live encoder. It is now possible to live encode multiple MPEG-H Audio streams, transmitting the main one over the broadcast path while the broadband path delivers additional streams. This will give viewers at home the option to personalize their experience and enhance broadcast content with additional features received over broadband.

Live sports events are a good example of the benefits of hybrid delivery: here, a broadcaster could decide to provide a UHDTV service with ambience audio and the English commentator in one MPEG-H Audio stream over an ATSC 3.0 broadcast path, and other languages or premium commentators in additional MPEG-H Audio streams via an ATSC 3.0 broadband path. An ATSC 3.0 TV set without an Internet connection would then receive the complete program in English, while ATSC 3.0 TV sets connected to the Internet would also be able to receive the additional streams, allowing viewers to select and enable the new features.

Fraunhofer IIS and its partners have put together the world’s first ATSC 3.0 hybrid delivery chain with MPEG-H Audio, which includes the MPEG-H Audio-enabled ATEME TITAN Live encoder plus the ATRunner from S&T and UniSoft. The latter serves as an ATSC 3.0 broadcast stream generator, providing the ROUTE sessions and ATSC 3.0 Low Level Signaling (LLS). Visitors can experience the pioneering solution at the upcoming NAB Show in Las Vegas from April 8 to 11, 2019.
