Lawo Introduces RAVENNA-Based Commentary Solution for Standard IP Networks

October 14 2013, 13:01

Lawo LCU_SetupWebLawo’s cost-efficient and flexible Commentary Unit (LCU) was developed in close cooperation with Host Broadcast Services (HBS), a Swiss company specializing in producing multilateral video and audio feeds for TV and radio from world-class international sports events. The fully digital system is based on RAVENNA, a real-time audio-over-IP networking technology that enables the use of standard IP networks to interconnect venues and devices, which provides savings in cabling while increasing the system’s flexibility.

“Good commentary plays a key role in the success of global events. The Lawo Commentary solution was developed in the very best interest of the Rights Holding Broadcasters of these events”, says Jörg Sander, CTO at HBS.

The LCU is designed to be easy-to-use for commentators, freeing them to focus on their tasks rather than managing the technology. It provides an intuitive user interface for up to three commentators per LCU. Lawo quality mic pre-amps and uncompressed real-time audio-over-IP (24 bit/48 kHz) ensure audio quality. All activity is indicated in a backlit LCD, indicating each control’s label and current setting. The unit also features three coordination lines, again with individual volume and pan settings. A Help key completes the user interface, giving commentators fast access to a support engineer. For emergency operation, the device provides an analog Mix Out and an analog input to feed the phones’ monitor mix. The Aux In can also be used to feed external sources (e.g., audio recorders) locally to the LCU.

The LCU is complemented by the Lawo Commentary Control Software, which replaces the commentary control units usually associated with two-part commentary systems, providing an integrated user interface to operate a complete commentary installation. The software is optimized for touchscreen operation, offering easy and efficient support for up to 20 commentators per screen. It shows the real-time status of all connected devices and manages all LCUs within the network, as well as the system’s DALLIS frame, which is Lawo’s modular I/O system for interfacing the commentary installation to the outside world. The software also enables a support engineer to listen to any signal of any LCU. Its remote-control facilities mean that most help requests can be resolved with a mouse click.
