RTBF Takes Digigram to Chicago
— During the 2012 U.S. presidential election, Belgian national TV
and radio broadcaster RTBF sent a team of audio engineers to Chicago,
Ill., to manage live coverage from a restaurant in the area and
ensure smooth delivery of audio to our main RTBF studio in Brussels.
were able to configure this unusual location into a mobile studio
thanks to Digigram’s V*MOTE, a software-based codec. The software
met our requirements for a light and reliable solution, capable of
matching the local IT infrastructure constraints and delivering high
main challenge our team faced was to set up a mobile solution that
would ensure live coverage, using a public Internet network, without
interruption. Sound engineer Miguel Allo worked onsite to set up and
manage a studio at the Chicago restaurant — without any specific
network infrastructure — to generate a live feed between Chicago
and Brussels throughout the election night. The feed consisted of
live interviews and commentaries over prerecorded audio.
we were facing complex technical conditions, we made the choice to
rely on a fully mobile solution that allowed us to ensure the live
broadcast and the recording of this worldwide event that matched our
high-quality audio standards.
solution we implemented for our live election coverage centered on
Digigram’s V*MOTE audio over IP software solution. We installed
Digigram’s Ultra Mobility solution, which provided the on-scene
RTBF reporter with the V*MOTE software codec running on a laptop
equipped with the Cancun soundcard while the Brussels-based studio
used the Iqoya *Call/LE hardware codec.
Relying on a
symmetrical RTP protocol, the team used HE-AAC v1 64 kbps codec
algorithms for the two-way link between the Chicago studio and the
Brussels studio. Everything got up and running perfectly. The audio
quality was excellent, and we had the impression that the reporter
was located in our studio in Brussels.
this broadcast operation resulted in almost 12 hours of live content,
without any drops from the local network at a time during which the
team could have faced some network saturation due to all of the
competing reports that night. We particularly appreciated the ease of
use of V*MOTE, the ability to deploy a completely mobile solution and
the capacity to set-up a simple and cost-saving infrastructure, in
terms of both human and technological resources. We were amazed.
