Fed up of poor network connectivity causing audio streams to drop when you’re on the go? xHE-AAC puts an end to that. The latest addition to the AAC codec family offers maximum coding efficiency, with a bit rate range spanning from 12 kbit/s up to 500 kbit/s and above for stereo services. Combining this with seamless bit rate switching over DASH and HLS, and mandatory MPEG-D DRC Loudness and Dynamic Range Control, xHE-AAC is the ideal solution for adaptive audio and video streaming services – whether it’s for movies, music, audiobooks or podcasts – as well as for digital radio broadcasting. The codec is natively supported in Android 9 Pie, and will be showcased at Fraunhofer’s NAB 2019 booth in video and Internet radio streaming applications.
In a dedicated “living room”, the Fraunhofer 3D soundbar reference design will demonstrate how to deliver cinema-style immersive sound to consumers in a convenient, high-quality fashion. At its core: the upHear Immersive Audio Virtualizer. Developed to enable the most immersive consumer experience from soundbars and TVs, the technology supports the rendering of 3D audio content as well as the upmix of legacy surround or stereo audio.
Fraunhofer IIS will showcase the most advanced audio features of the ATSC 3.0 next-generation standard with an MPEG-H Audio end-to-end chain for broadcast and DASH streaming, as well as the latest production tools and authoring units for creation of MPEG-H Audio content. Next-Generation Audio is already a reality with MPEG-H – the audio system enabling immersive and interactive sound together with enhanced accessibility features has been on the air 24/7 in South Korea since the launch of its UHDTV system in May 2017. The system is designed to work with today’s broadcast and streaming equipment and all equipment featured in the real-time chain presented at NAB is readily available.
JPEG XS is a new mezzanine video codec targeting highest quality for slight compression rates at low complexity and low latency. It addresses the needs of the broadcast industry to send production feeds over multiple Ethernet based links and offers visually lossless quality while reducing the amount of data by a factor 10. A SDK (Software Development Kit) for en- and decoding of JPEG XS in real time is available for Windows and Linux and can be licensed.
At NAB 2019 Fraunhofer IIS shows capturing and live-streaming a 4K video stream over an IP link with real time en- and decoding by software.
