A variety of Ravenna-enabled products are on show at the ALC NetworX stand. Of particular note is the latest version of the Lawo Commentary System, 500 of which were used during the recent UEFA Euro 2016 football championships.
Initially developed in collaboration with HBS for the 2014 World Cup, the fully digital system is based on the real-time, AoIP networking technology, Ravenna, which enables the use of standard IP networks for interconnecting venues and devices.
For the Euros there were 50 LCUs (Lawo Commentary Units) per stadium (500 in total) all networked over IP via Ravenna, plus 30 LCC (Lawo Commentary Control) PCs and 46 Lawo DALLIS modular I/O units for audio breakout (three at each venue, 16 at the IBC). The DALLIS frame provides complete connectivity for up to 20 commentary units per Ravenna-enabled LCG (Lawo Commentary Gate) concentration card, and a total of 360 LCUs per frame.
All the components including the LCG concentration cards and the commentary units themselves are connected to the LAN/WAN network, thus enabling remote monitoring and control of the complete installation.
