During the 2012 U.S. presidential elections last November, we 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. We were able to configure this unusual location into a mobile studio thanks to V*MOTE, a software-based codec solution provided by Digigram. The software from Digigram met our requirements for a light and reliable solution capable of matching the local IT infrastructure constraints and delivering a high standard of audio quality. The 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 on site to set up and manage a studio at the Chicago restaurant without any specific network infrastructure to generate a live session between Chicago and Brussels throughout the election night. Those live sessions consisted of live interviews and commentaries over prerecorded audio. Although 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 perfectly our high audio quality standards. The 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 local studio used the IQOYA *CALL/LE hardware codec. Relying on a symmetrical RTP protocol, the team used AAC HEv1 64Kbps codec algorithms for the two-way link between the Chicago studio and the Brussels studio. Everything got up and running perfectly from Chicago. The audio quality was excellent, and we had the impression that the reporter was located in our studio in Brussels. We were amazed! Overall, this broadcast operation resulted in nearly 12 hours of live content without any drop on the local Internet network and at a time during which the team could have faced some network saturation. We particularly appreciated the ease of use of V*MOTE, the high audio quality, the ability to deploy a completely mobile solution, and the capacity to set up a simple and cost-saving infrastructure both in terms of human and technological resources. the author of the text is Laurent FLEMAL, head of RTBF Digitization Division. for your question, the V*MOTE was in Chicago and the CALL/LE was in Bruxelles.
