ORS and VIDI

Successful cooperation

1. Transmission of live images of the games of the german ice hockey league (del 2013/2014)

At the start of the DEL season 2013/14, the fail-proof fibre optic network planned by VIDI GmbH was put into operation for the transport of the TV production signals from 14 German ice hockey stadiums to the Red Bull Media House located in Salzburg.

In mid-September, 2013, a hyper modern live network for the transmission of all games of the current DEL season went into operation with the match ERC Ingolstadt versus Eisbären Berlin - Berlin polar bears. The specialist for video transmission, the German VIDI GmbH from Darmstadt was ORS' partner for the design and implementation of the video wide area network, the technical fibre optic connection of all 14 halls in Germany, the ARD neutral point in Frankfurt and ZDF in Mainz and of signal feed to the Red Bull Media House in Salzburg.

Technical performance data of the digital network
Three HD transmission paths to Salzburg, two HD reception paths, one LAN connection 10 MBit/s for data communication at a GB-Ethernet interface and an equivalent LAN connection for voice communication.

What posed particular challenges for the designers of the network configuration was, in addition to a fail-proof redundant signal routing, the varying duration (a game may last up to four hours) and the fact that several games take place simultaneously.

2. Signal transmission of the Confederation Cup 2013 from Brazil all over the world

The ORS team and the German transmission specialists VIDI were in charge of signal transmission of all football games of the Confederation Cup 2013.  The team had already demonstrated its high quality performance during EURO 2008 and EURO 2012 - the games were broadcast without any technical disruption.  

Numerous VIDI and ORS transmission specialists took over the video signal on site from the broadcast van which stood directly in front of the respective football stadium. There, the video signal was subsequently processed and further transmitted via fiber optic lines to the IBC (International Broadcast Center). From IBC, the games were broadcast via broadcasting stations throughout the world.

4K absolute visual quality
The Confederation Cup marked an important milestone for the future of live sports broadcasting in 4K format. During the Confederation Cup, these new approaches to technology and production were tested with three football games. 4K provides fourfold definition compared to 2K and is successfully used for cinema productions.  Content recorded in 4K format display absolutely perfect visual quality.

3. Football world championship 2014 - smooth Video Signal transmission

ORS was in charge of live broadcasting the world championship soccer matches (12th June to 13th July, 2014) under the leadership of VIDI, the German transmission specialist.

A team of some 50  VIDI und  ORS staff was responsible for the smooth video signal transmission of the 2014 football world championship from 12 venues in Brazil.

Over eight tons of technical equipment was shipped to Brazil.  Technical equipment such as encoder and multiplexers were set up and tested by ORS and VIDI staff beforehand by way of trial so that no disruptions would occur on site during live broadcasting of the games and everything would run perfectly well – which was the case in the end.  Detailed training for all technical equipment ensured a great TV experience for all football fans all over the world.

The path of the TV signal

  1. Live broadcasting of football world championship games
  2. Reception of TV camera signals
  3. Signal processing and adaptation to fiber optic lines 
  4. Signal transmission by ORS/VIDI to FIFA
  5. Worldwide signal transmission to broadcasters holding broadcasting rights
