Next Gen TV Audio Test A Success For Verance, Dolby

April 04, 2019 / Michael Balderston

Following the announcement of a successful test of an ATSC 3.0 standard component on Wednesday, another element of Next Gen TV has received a passing grade during a separate experiment. Verance Corporation and Dolby revealed they conducted a test in February with San Diego station KPBS on internet-delivered dialogue enhancement, a Next Gen TV personalized audio experience. Using the Verance Aspect watermark and Dolby AC-4, the test demonstrated that the dialogue enhancement feature of the AC-4 can be delivered as a standalone audio stream over the internet and paired with video delivered through a live linear broadcast. The companies reported that the pairing was made with precise broadband audio and broadcast video synchronization, and delivered over all MVPD paths, including cable and satellite. After delivering dialogue enhancement over a live linear 1.0 broadcast environment, Verance and Dolby are said to be planning to replicate the test with an ATSC 3.0 broadcaster.
