Digital TV Labs and Fraunhofer IIS have joined forces to develop the world’s first MPEG-4 HE-AAC audio test suite for DVB receivers now available to broadcast device manufacturers.

Digital TV Labs, the digital media and device testing expert that specializes in testing tools and services worked in conjunction with world-renowned audio technology specialist Fraunhofer IIS, to launch the new MPEG-4 HE-AAC audio conformance test suite for DVB receivers. The test suite is designed to measure compliance for MPEG High Efficiency-Advanced Audio Coding (HE-AAC), the world’s most efficient high-quality multi-channel and stereo audio codec that was co-developed by Fraunhofer IIS.

The HE-AAC standard has been deployed globally in TV & Radio broadcast systems such as ISDB-T, SBTVD, DMB, ATSC-M/H, 3GPP, HbbTV, DAB+, and Digital Radio Mondiale. It is the de-facto standard for mobile streaming and natively supported by over 7 Billion devices. HE-AAC for DVB audio encoding is standardized by TS 101 154 and supports the full set of DVB/MPEG metadata.

Digital TV Labs is providing two core offerings, available to consumer electronics manufacturers and semiconductor suppliers; the option to license the DVB Receiver Test Suite for HE-AAC conformance and a complete testing service and report, both of which can be used to test products for verification of the audio standard.

The new HE-AAC DVB test suite will be built on existing extensive test streams from both organizations. It will enable efficient validation of end-user platforms and ensure interoperability with broadcast audio services.

Keith Potter, CEO of Digital TV Labs says: “We are delighted to be working with Fraunhofer IIS in rolling out this exciting program. This new development will provide for the first time a comprehensive test suite that will provide full HE-AAC coverage and compliance validation for DVB receivers.”

Harald Popp, head of the Audio & Multimedia Business department of Fraunhofer IIS added, “Fraunhofer’s goal has always been to deliver high quality implementations of advanced audio technologies to the rapidly evolving media world. With the HE-AAC audio compliance test suite of Digital TV Labs, manufacturers can make sure they deliver that high-quality audio and multimedia experience also to end-users.”
