Optimization for cost and
remote efficiency
Distributed workflows, IP studio connectivity and immersive live
experiences are all driving innovation in audio codecs
- by Adrian Pennington...
W
ithout
question, the main
facilities' focus these days is
reducing the real estate footprint.
With the majority of the broadcast
workforce having shifted to work
from home, most station owners have
questioned the need for large offices
that remain empty - even as social
distancing and mask mandates are
lifted. Since most modern facilities
are internet connected and primarily
controlled by computers, the pivot to
this new working mode was already
in place and firmly nudged into
operation by the pandemic.
" In 2020, it was a good time to
be in the remote broadcast codec
business, " says Chris Crump, Senior
Director of Sales and Marketing at
Comrex. " We were making codec
hardware as fast as we were shipping
them. But we knew that
there
was a segment of the broadcast
community that needed a different
kind of tool that provided a Comrexlike
experience without expensive
hardware on the contributor side. Our
ACCESS and BRIC-Link line of codecs
definitely have a place for most types
of remote contribution, but we felt
that guests and expert contributors
needed an easier to use tool that
relied
on equipment
they were
familiar with such as a computer
or smartphone.
" Our new Gagl subscription
just
service does
Chris Crump, Senior Director of
Sales & Marketing for Comrex
that.
By using a headset on a
computer or smartphone,
Tieline's Gateway and Gateway 4 audio codecs receive incoming IP audio streams
the guest or contributor clicks on a
link provided by the host via email
or text. The link opens a common
web browser on their device. The
guest immediately
joins the Gagl
session with high quality, low delay
audio. The moderator of the Gagl
session connects the conferenced
to an ACCESS or BRIC-Link codec
in the broadcaster's studio for live
broadcast. Up to five participants
can take part in a Gagl with all of the
audio internally conferenced. "
Gagl
is
the
successor
to
the
company's Opal and operates in a
very similar fashion using a common
web browser but for single instances
on a dedicated hardware device.
" The success
of
Opal
with
broadcasters throughout the world
and feedback from program directors
and content
producers has been
instrumental in the development of
our new Gagl subscription service
which will certainly become a goto
choice for broadcasters. "
While the trend is for broadcast
studio infrastructure to
be more centralised and IP based,
contributors
are more distributed,
either through necessity, or to trim
costs and increase profitability. IP

Charlie Gawley,
Tieline VP Sales APAC/EMEA.
" The pandemic
accelerated
shift
to working remotely
through
necessity, which has also created an
acceptance of IP technologies as the
way to reliably broadcast remotely.
On the studio side, manufacturers
are embracing equipment that
AES67, ST 2110-30 and ST 2022-7
compliant, to allow centralised
control of audio and video streams in
the broadcast plant. "
As a specialist

level of capability and redundancy, "
says Gawley.
On
the
Gateway
studio
and
side,
Tieline's
Gateway 4 audio
codecs receive incoming IP audio
streams. The Gateway acts as an AoIP
gateway/bridge between AoIP sites
worldwide carrying all synchronised
audio and
data. Gateway
Gateway 4 are compliant with AES67,
ST-2110-30, RAVENNA and
now
Tieline is introducing native support
for Livewire+ AoIP networking in
these codecs.
" This
delivers
seamless
interoperability with a large variety
of vendors making life so much
easier for broadcasters, " Gawley
says. " An optional WheatNet-IP card

WheatNet

support for Dante in coming months
with an optional Dante card. No
other codec supports this level of IP
interoperability. "
