The comprehensive set of test cases offered by Ligada iSuite for DASH include conformance testing for segmented video streaming, such as  the insertion of advertisements in both on-demand and live delivery modes. It provides tests for audio and video codec support and multiple MDP types.

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).


Ligada iSuite for DASH Pro

Ligada iSuite for DASH Pro additionally includes network emulation control that allows the user to simulate adverse network conditions by adjusting the available network bandwidth, delay, or the amount of packet loss occurring on the network connection between the DASH server and the client under test. Ligada iSuite for DASH Pro provides test cases to cover the Network Emulation Profile 2 of the DASH-AVC/264 test cases, based upon test patterns defined in recommendation ITU-T G.1050. It also includes a Network Activity monitoring capability - a new feature to the Ligada iSuite Test Harness to help diagnose and debug network-related client playback issues.The Test Suite contains over 140 test cases, containing Live and On-Demand profiles with associated media files.

Ligada iSuite for DASH Pro enables customers to stress test their DASH implementations cost effectively, without the need for expensive dedicated hardware or software solutions to replicate network impairments. Additionally, all test projects can be managed within the central Test Harness meaning that results are captured and reports are created within the same framework.

Ligada iSuite is a widely adopted, versatile Test Harness, supporting a number of OTT, IPTV and hybrid services. This enables manufacturers and developers to test for conformance, interoperability and to meet standards specifications for certification. Our licensing model provides access to updates and new test cases within each Test Suite as standard and additional Test Suites as required.
