New MPEG-DASH development kit enables partners to deliver
high-quality audio for HD streaming
LAS VEGAS--(BUSINESS WIRE)--
Dolby Laboratories, Inc. (NYSE: DLB) today announced the availability of
a development kit to bring the full power of Dolby® Digital
Plus premium-quality multichannel audio to partners that leverage the
MPEG Dynamic Adaptive Streaming over HTTP (MPEG-DASH) standard. MPEG
ratified MPEG-DASH in November 2011, and it is quickly gaining traction
as a mainstream delivery format for streaming content over the Internet.
"Netflix® welcomes the growing support for emerging online
standards, including MPEG-DASH and the associated common encryption
specification for ISO files. These standards will enable continued
efficient and high-quality integration of over-the-top services like
Netflix across a wide range of devices," said Mark Watson, Director,
Streaming Standards, Netflix.
Dolby technology has been selected by leading online video services
including Netflix, HBO Go®, Vudu™, Best Buy®
CinemaNow®, Samsung™ Acetrax™, Dixons KnowHow™ Movies, Voddler®,
Apple® iTunes®, and Amazon® Instant
Video. This development kit will enable current and future partners,
such as encoder vendors and digital rights management (DRM) vendors, to
easily implement and test Dolby Digital Plus for products and services
in the online video ecosystem. The development kit includes test vectors
as well as specifications that describe how Dolby Digital Plus can be
signaled and transported within MPEG-DASH, Microsoft® Smooth
Streaming, and Apple HTTP Live Streaming (HLS).
"The emergence of the MPEG-DASH specification is an important step in
the maturation of adaptive bit-rate delivery for multiscreen video,"
said Tony Huang, Senior Product Manager, Broadcast and Live, Digital
Rapids®. "We're excited to be extending our support for Dolby
Digital Plus audio to DASH, enabling our customers to bring premium
content with high-quality audio to their audiences on any compatible
device in a reliable and consistent manner."
"Envivio is closely collaborating with Dolby to provide Dolby Digital
Plus alongside AVC/H.264 video at different bit rates while supporting
seamless adaptive switching, enabling our customers to deliver
high-quality multichannel audio entertainment to consumers on any
compatible device while lowering their operational costs," said Arnaud
Perrier, VP of Solutions, Envivio®. "As the DASH standard
becomes more universally adopted, even more service providers will be
able to leverage these technologies."
"As more consumers enjoy streaming content on multiple screens, it's
increasingly important that the entertainment experiences are the best
quality, regardless of delivery medium and playback devices," said
Thierry Fautier, Senior Director of Convergence Solutions, Harmonic. "We
look forward to working with Dolby to improve content delivery to
connected and portable devices. Harmonic and Dolby believe that when
consumers enjoy entertainment over the Internet, they never need
compromise on quality."
Dolby Digital Plus enables the delivery of high-quality audio to any
compatible device and any distribution workflow, including broadcast,
over-the-top (OTT), online, and on demand. It includes scalable,
adaptive, and bandwidth-efficient multichannel coding designed for
bandwidth-constrained delivery networks, as well as technologies such as
loudness control and device-playback sound optimization. Widely
supported within the digital entertainment ecosystem, it is available on
more than 640 million products, including connected TVs, smartphones,
tablets, PCs, game consoles, and Blu-ray™ players, making it the
preferred audio solution for artists, operators, carriers, and device
makers worldwide. Dolby is demonstrating how Dolby Digital Plus enhances
entertainment experiences across platforms and screens at NAB Show®
2012 (booth SU1212).
