DTS, Fraunhofer Offer Sound Advances at IBC
Two audio powerhouses offer high-definition multichannel streaming audio at lower bitrates.
Bringing an improved audio experience to the streaming video world, both DTS and Fraunhofer made significant announcements at the IBC exhibition currently underway in Amsterdam.
DTS announced that both Elemental and CastLabs will support live streaming of DTS-HD audio through MPEG-DASH. This will bring an immersive, high-definition audio experience to sports and music events, says DTS. DTS-HD offers 5.1 surround sound for computers, mobile devices, set-top boxes, and connected TVs. Elemental will add DTS-HD to its Elemental Live video processing system, while CastLabs will support DTS audio in its iOS and Android players. Those wanting a closer look, or listen, should visit DTS's IBC stand.
Meanwhile, Fraunhofer is showing off its own DASH-based streaming solutions at IBC. Attendees can sample Fraunhofer's DASH streaming with 7.1 HE-AAC multichannel audio and HEVC video coding. The institute says that the combination of these two codecs with DASH adaptive streaming is the most efficient way to stream high-quality content at low bitrates, using ISO standards. HE-AAC, it notes, allows for seamless audio bitrate switching and surround sound, and doesn't need to switch to stereo audio when bandwidth is low. Fraunhofer is showing off this and other MPEG-DASH technologies at IBC booth B80 in hall 8.
At its CES booth, Fraunhofer is giving an audio tour to what people can expect from the upcoming MPEG DASH specification.
When Paramount begins distributing CFF UV titles in the second half of this year, it will use DTS for high-definition audio.
