A well-known manufacturer of fibre based solutions for the audio industry has provided a complete SD/HD/3G-SDI video solution using the DiViNe (Digital Video Network) transport platform.
In 2011 representatives of Studio Hamburg MCI approached Marc Brunke’s design team to come up with a video routing solution for the new studio facility at the Swedish Television (SVT).
Marc Brunke formed a new company, BroaMan GmbH, based on the experience gained from Optocore, which has traditionally provided optical fibre network solutions for the large-scale events industry, and went to work on a modular transport and routing system that lead to the creation of DiViNe – The Digital Video Network.
Using the DiViNe modules, BroaMan came up with a unique proposal consisting of four independently configured automatic routing systems using a modern, fibre-based video StageBox concept.
“The ability to do this had not existed previously,” explained Marc Brunke, “The customer is not willing to pay extra for something he is not going to use. In this project the system has been entirely cost-optimised to the needs of the customer using the modular components of the DiViNe platform. Upon connection, the system discovers where the portable StageBox is connected and the central Video Router routes the assigned channels to the correct position.”
The devices offer routing and signal repeating, as well as the ability to convert the signal from electrical (BNC) to optical (fibre). Every product was configured independently to offer the most suitable solution for the customer.
The Video Router
The first and the most powerful system is based around a centralized Video router with 8 portable StageBoxes that can be connected to any of the 32 wallboxes within the studio facility.
The central routing system is based on Route66 2RU frames:
- Four of the frames are configured as 3G-SDI to fibre converters with routing capabilities. Providing sends to the portable StageBoxes.
- One frame is configured as fibre to 3G-SDI converter with routing capabilities. Providing returns from the portable StageBoxes. One frame is configured as an OPTOCORE router. Providing management and discovery for the network.
Two CWDM modules. Providing multiplexing to the 32 wallboxes within the studio.
The routing is fully automatic and based on the assigned ID of the portable StageBox. It does not matter to which of the 32 wallboxes a StageBox is connected to. The router will automatically discover the StageBox and route the 4 3G-SDI sends, 1 3G-SDI return and RS422 serial control signals assigned to the portable StageBox to the wall-box.

The Camera and Ceiling Router
The second system consists of two Camera routers and one Ceiling router with 3G-SDI inputs and fibre transmitters, providing outputs to 15 portable StageBoxes.
Routing is controlled with the VSM controller provided by the company LSB. Integration with other controllers is optional.

The Light Car Router
The third system consists of one Light Car router based on a Route66 frame and one portable StageBox based on a Repeat33 frame. As in the Video router system, the Light Car router provides automatic routing. Video is routed together with the OPTOCORE stream from the centralized Route66 2RU frame.
Connection between the Light Car router and the portable StageBox is possible in five different locations using a 4 core fibre cable.

Electrical-Optical-Electrical converters
The fourth system consists of multiple Repeat48 devices that convert and distribute approximately 200 3G-SDI channels throughout the facility. Due to the modular design, each device provides a different number of I/O interfaces, adding flexibility to the overall system design.
