A diverse group of technology leaders have formed the DASH Promoters Group, in an effort to push the adoption of MPEG's DASH (dynamic adaptive streaming over HTTP) standard.
DASH, ratified in November 2011, is designed to improve the quality of streaming Internet video by dynamically adapting it to changing network conditions as video streams to a device. It is designed to solve problems such as intermittent stalls, poor video quality under changing network conditions, and significant video start-up lag.
Microsoft, Netflix, and Qualcomm are the founding members of the DASH Promoters Group . Other current members include: Adobe, AEG Digital Media, Akamai, BuyDRM, Digital Rapids, Digital TV Labs, Dolby, EBU-UER, Elemental, Envivio, Ericsson, Harmonic, Intertrust, NDS, Packet Ship, Path1, RGB Networks, Samsung, Thomson, University of Klagenfurt and ZiXi.
The group has been demonstrating DASH streaming video at Mobile World Congress 2012 in Barcelona this week. The demo featured a live video stream encoded for DASH ISO-Base Live Profile by Harmonic, ingested to Akamai's Content Delivery Network and delivered to a Snapdragon processor-based mobile development platform from Qualcomm for playback.
"Demonstrating the live ingest of DASH content and the dynamic synthesis of DASH manifests and segments is the first step toward DASH leveraging the benefits of capacity, efficiency, and security brought by the Akamai Intelligent Platform," said Will Law, principal architect, media division, Akamai.
"Public interoperability demonstrations among encoders, media delivery systems and playback clients inspire market confidence for this new format. DASH brings the promise of convergence in media delivery, as well as improvements in encoding and distribution efficiency, rights management and the overall consumer viewing experience."
"Harmonic is very committed to the DASH technology," said Thierry Fautier, senior director of convergence solutions at Harmonic Inc. "We believe DASH is the only way to effectively scale video over the Internet. We're excited to be the first video company to demonstrate solutions based on DASH technology at Mobile World Congress."
The DASH Promoters Group is also working toward recommended deployment configurations for DASH, informally called DASH-264. This would enable a minimum set of DASH requirements for the industry and help enable further commercialisation of mobile devices that support it.
