In 2009, Digigram claims to invent
the first stereo audio codec dedicated
to transport over IP networks which
natively integrated the redundant
streaming function on two separate
networks.
While radios already offered several
simultaneous
audio
programs,
Digigram chose to propose a codec

talk-back
channels
and
commentaries via IP. It had to
support remote broadcasting
of programs between remote
studios and generate multiple
WEB radio streams for CDNs. This
led to the creation of IQOYASERV/
LINK, codec which formed the
basis for many of its subsequent
products.
IQOYA TALK, for example, is a
portable IP audio codec dedicated to
live remote broadcasting for radio and
TV. Designed with an intuitive userinterface as simple as a smartphone,
IQOYA TALK allows remote reporters
to perform all the key actions in
just two clicks. Live reporting or
commentary can be performed, as
well as studio quality interviews for up
to four journalists and guests. Audio
content is streamed through a large
number of wired or wireless 'last mile'
connections.

studio-to-transmitter links. With its
entry-level cost, it also remains a
popular choice for home studios.
" Since I installed the BRIC-Link, I
haven't had any issues - I've barely
needed to touch it, " said Rob Carson,
an independent podcaster. " If I have
any service disruptions, I disconnect
and reconnect in seconds. It's the best
thing I've ever worked with. "
" BRIC-Link keeps a consistently
strong connection even over our

co-host of The Bob And Zip Show.
" The quality of our real-time radio

the material for our podcast is also
exceptional. BRIC-Link is an integral
part of our entire creative
process, and we couldn't
collaborate without it. "
