LIVE HD-BROADCAST SYSTEM AT THE 12th IAAF WORLD CHAMPIONSHIPS

Broadcast Microwave Services Europe provides Broadcast System at the 12th IAAF World Championships Athletics Berlin 2009TM

KEMEL, GERMANY; September 7, 2009 — At the IAAF World Championships, BMS established 10 next-generation HD wireless links operating between 3 and 3.5 GHz. These systems transmitted close-ups of the athletes in the interior of the arena to the ENG/OB (electronic news gathering/outside broadcast) vans in the TV compound outside the arena. There, stage directors chose the best pictures for the worldwide audience to experience.

The demands of the IAAF World Championships required hyper-flexibility for stadium broadcast staff to switch mobile camera positions within the arena very quickly. BMS' transmission technique allowed the reliable use of 64QAM modes. By doing so, BMS' proven FFT-MRC (FFT-Maximum Ratio Combining) diversity method could be used; furthermore, there was no need for manufacturer-specific modulation.

The BMS system, linked via TopVision's triax cabling throughout the stadium, covered the whole arena with only four receiving antennas positioned around the stadium. Additional BMS-manufactured equipment included downconverters, UHF-splitters, and switches. Transmitted signals were sent to the receive site on the ENG/OB van via 500m triax cables, where it was distributed to 10 BMS diversity receivers via a switching system. This setup reduced cabling?especially in the sensitive areas of the stadium?to a minimum, increased reliability and simplified equipment set-up and tear-down.

Further, BMS transmitters were mounted in the back office to remotely control all of the wireless cameras' parameters from the director?s location. All spectrums of the receivers' incoming signals could be quickly checked and monitored at a glance using BMS-developed software, DENGVision, to immediately identify possible irregularities and react accordingly.

Broadcast Microwave Services' (BMS) European office, provided a full-service system of High Definition broadcast services at the 12th IAAF WORLD CHAMPIONSHIPS IN ATHLETICS BERLIN 2009TM (www.berlin2009.org), Germany's and worldwide top sporting event of the year. Working together with TopVision GmbH, the leading German sports production company from Berlin, BMS and TopVision raised the bar for live HD broadcasting at the prestigious national and international sporting event.

Drawing on significant RF experience and following a strict frequency management were mandatory in putting the complex task of live-HD transmission including camera remote control into practice. By providing both, BMS ensured the best results for the users and audience.

BMS Inc. Vice President, Reinhard Kühn, commented at the event, saying, "BMS Europe is proud to have supplied the complete live-HD broadcast package at the IAAF. This event is watched closely by the sporting event community not only for the athletic competition, but also for the application of cutting-edge broadcasting technologies."
