MPEG Dynamic Adaptive Streaming over HTTP (MPEG-DASH) seeks to simplify and unify adaptive streaming by building on existing bespoke variants that are currently deployed. It offers broadcasters, operators, and OTT / IPTV only platform owners the ability to simplify encoding and distribution methodologies to reach new audiences across multiple devices cost effectively.

Some of its advantages over other  adaptive streaming formats is that MPEG-DASH is an open standard (ISO / IEC 23009 ratified in 2012) and supports multiple DRMs, closed captions and multiple audio tracks to enable different languages.

A major stumbling block has been true client / server interoperability and a comprehensive functional conformance test suite: Ligada iSuite for DASH is the answer.

Digital TV Labs is a member of the DASH Industry Forum and contributes to the development of the standard. With experience in developing multiple test suites utilising MPEG-DASH within the HbbTV (Hybrid broadcast broadband TeleVision).
