Trilogy Supports All-IP Live Broadcast Production

Trilogy, a supplier of intercom solutions and master reference generators for the broadcast industry, was one of a group of industry partners who supported the European Broadcast Union (EBU) and Belgian public broadcaster VRT's successful remote production of a live music concert using IP across the entire production chain.

The remote production set-up was an extension of a full IP local studio set-up and previously demonstrated by the project group in August 2015. The concert venue, Bozar, in central Brussels, was connected to the Live IP control room at VRT Brussels by a single 10km long optical fibre cable, carrying an IP network.

Included in the Live IP setup was Trilogy's Gemini distributed matrix intercom system, IP panels, and virtual panel application, all running across CWDM technology from Nevion, which enabled optical bi-directional IP-streams to be modulated on a single 10km long optical fibre cable.

The Gemini system is based on a distributed matrix IP-based architecture, which removes the risks associated with a single point of failure. With further centralised control capabilities via Ember+, Gemini ensures tighter overall control intercom systems as a consolidated part of the entire broadcast infrastructure.

The IP data transported in each direction via optical cable was enough to connect four IP cameras, 10 microphones, Gemini intercom, control signals, camera return signals, and a virtual intercom system via Trilogy's Virtual Panel application. Importantly, the latency of Trilogy's VoIP intercom system was so low that it was unnoticeable to the production team.

Trilogy's mix of physical IP control panels and software-based virtual panel applications for the project provided high performance intercom control. Trilogy's Virtual Panel software provides a new level of flexibility and cost effective access points because it can be installed on smartphones, tablets, desktop PCs, and laptops with support for most popular operating systems.

Trilogy Product Specialist John Sparrow said: "Trilogy pioneered IP-based intercoms and as a company has been working in that environment for more than 15 years. Gemini has had integrated IP capability from the start and has proven to be extremely popular with users worldwide. We're proud to support the Live IP project and its partners as further acknowledgement of just what can be achieved in a total IP production chain."
