The group operates two development laboratories with more than 50 PCs and Workstations running various Windows and Unix flavours.

A dedicated IP/DVB and MHP Test Center has been recently set up, interconnecting the IRT/MHP Playout Server with an IP/DVB encapsulator/multiplexer and several set-top boxes and PCs over three DVB transmission chains (DVB-S, -T, -C) in a local loop trial environment. Several analysers for TS/MPEG-2 level and MHP are available for monitoring and verification purposes.
