Alfacam takes Riedel to South Africa

Belgium based and international TV broadcast and OB truck provider Alfacam has equipped five HD OB trucks that will be used for the FIFA Football World Cup 2010 with a comprehensive MediorNet installation from Riedel Communications.

Alfacam is in charge of the world feed production at the venues in Johannesburg, Pretoria, Durban and Port Elizabeth. Besides this production, Alfacam is responsible for the unilateral signal for ARD/ZDF, the German public broadcasting. Therefore, Alfacam will send 8 OB trucks, 80 cameras and about 35 top technicians to South Africa. Alfacam was assigned for about 45% of the "host feeds” of the WC 2010 and will deploy in total 170 cameras and 155 technicians.

The MediorNet mainframes link Alfacam’s trucks with the technical operation centres (TOC) in the stadiums, delivering 16 HD-SDI signals including the world feed to the trucks and four back from the OB van to the TOC. MediorNet’s integrated CWDM multiplexing provides maximum fibre efficiency and allows transporting all HD signals bi-directional via one single mode dual fiber link.

MediorNet’s integrated Embedding/De-Embedding feature de-embeds the audio and delivers the signals via MADI to the trucks’ Lawo audio consoles. As the video and audio streams come from various asynchronous sources Alfacam also makes use of MediorNet’s Framestore feature, which synchronises the video signals to the truck’s internal clock, while the audio signals are synchronised via MediorNet’s Sample Rate Converter (SRC). After editing, the final HD video and audio stream is sent back to the TOC, from where it is forwarded to the IBC for the world broadcast of the event.

"With our task, to process the stadium’s cameras, the world feed of the games and to provide the feed for the German broadcast of the event, it is important that we can absolutely rely on the technology we use. MediorNet gives us all we need for this exciting broadcast operation while saving a lot of equipment such as de-embedders, framestores and such, which we would have needed with other solution", said Rene Alles, Project Manager at Alfacam Deutschland.
