Well, okay, sending a separate audio-enhancement over the Internet, and
synching it up with the OTA one-way linear broadcast, is a nice enough "tour de
force." But, as the article says,
1. This feature requires an Internet connection,
2. And it does not require ATSC 3.0.
Why the hyped-up title, then? If the Internet connection required is broadband,
and not merely dialup, then ..., right?

Next Gen TV Audio Test a Success for Verance, Dolby
Test of personalized audio experience done with KPBS in San Diego.
Michael Balderston Apr 4, 2019
SAN DIEGO-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.
Aspect is designed to ensure Next Gen capabilities like personalization,
interactivity and census-like audience measurement can reach 100% of ATSC
1/0/3.0-connected TVs, regardless of whether they receive content over-the-air,
via MVPD or OTT. The Dolby AC-4 encoder, meanwhile, is meant to be able to
power multiple personalized audio experiences.
"Together with Verance and KPBS, we have proven the value and impact Dolby AC-4
can play in hybrid broadcasts and demonstrated the growing importance of
next-generation features like better audibility, also known as dialogue
enhancement," said Mathias Bendull, vice president, multi-screen services
audio, Dolby Laboratories. "Not just a feature for the hearing impaired,
dialogue enhancement also enables all viewers to have a better experience when
dialogue is harder to hear, like a noisy room."
KPBS Operations & Technology Division Associate General Manager Bruce Rogow
says that viewers have sent complaints about background music and other sounds
drowning out voices in shows, and believes the technology tested by Verance and
Dolby could be a "game changer."
Joe Winograd, CTO of Verance, said: "Broadcasters investing in the development
of Next Gen TV applications can now proceed with confidence, knowing that these
applications are capable of reaching 100% of U.S. households, including 80% of
viewers currently using MVPD services."
