LTE – 4G enables German race in live HD

With state-of-the-art encoder and decoder technology from Teracue on-board, the Alpari World Matching Racing Tour opened its international sailing worldchampionship series. Taking place in Langenargen, Germany, the offshore images were broadcast live using LTE / 4G mobile networks.

During Match Race Germany at Lake Constance, which took place on May 15-20, the broadband initiative II founded by the Baden-Württemberg government demonstrated what outstanding potential the use of the mobile communication standard Long Term Evolution (LTE, 4G) has in combination with powerful glass fibre networks.

In a model project, various technology partners, including Vodafone, Alcatel-Lucent, TDT and Teledata, developed and installed an infrastructure on location, which allows for live images of the regatta to be broadcast from the water, as well as the air and even the shore using the new mobile communication standard LTE – 4G. As a result, camera signals were sent from regatta yachts, a plane and a high-shot camera placed on a jetty to an LTE base station installed on the mainland.

The IPTV specialist Teracue was also onboard with this model project, supplying the latest generation of encoder and decoder technology. For the stable broadcasting of live images from the boats and an ultra-light plane, the camera signals were converted into IP signals using a Teracue ENC-300-HDSDI encoder, sent to an LTE router and transmitted from there before being received on land.

The very robust encoders are ideal for outdoor and mobile use. Be it wind, spray or interference, the high-quality encoders ensure the stable and interference-free streaming of live images even under extreme conditions. In addition, the ruggedised fanless encoders can be used in almost any environment due to their low weight and compact dimensions making them space-saving, mobile and flexible, which is an enormous advantage for installation at live events and sports broadcasts.

On land, the IP streams were converted back into SDI signals by Teracue decoders (DEC-30-HDSDI) and sent to the event direction and video mixer. From there, the live images are played and distributed to the spectators using fibre glass.
