RTBF in Belgium

In early April and September 2020, RTBF, Belgium’s public broadcaster for the country’s French-speaking community, took delivery of two groundbreaking, full-IP OB trucks. The 12m long trailers had to be configured remotely in order to be delivered on time, due to the covid-19 lockdown.

Perfect examples of how to leverage the flexibility of Lawo’s C100 FPGA blade, the OB Twins come equipped with a 100Gbps Arista-powered spine/leaf network core (audio, video and matrix) that revolves around Lawo’s V__matrix platform for SDI- and IP-based video and audio input/output as well as processing.

Lawo’s VSM broadcast control system talks directly to the XVS-8000 IP vision mixer using NMOS-IS04/05 protocols.

Each truck offers 36 vm_dmv heads delivered through C100 blades for multiviewing purposes. Overarching control and orchestration is handled by Lawo’s VSM IP control system and theWALL for multiviewer arrangement.

The OB Twins support all audio formats in two resolutions (24 and 32 bits), which are mixed using an mc² 56 audio production console and 512 DSP channels provided by Lawo’s A__UHD Core.
