Domo Broadcast Transmitters Selected For Marathon Coverage

DTC, Domo Broadcast's SOLO HD transmitters and PRORXD 8-Way Diversity RF system has been selected to help deliver recent coverage of the 2017 Standard Chartered Mumbai Marathon.

Domo technology was deployed by Broadcast RF, who set up and managed the wireless camera coverage over diverse terrain of the 26-mile route. The marathon started opposite Chhatrapati Shivaji Terminus Mumbai, and passed many of the city's iconic locations such as Flora Fountain, Marine Drive, Chowpatty, Haji Ali, Mahim Church, and the Bandra–Worli Sea Link.

Domo SOLO HD transmitters were fitted to live chase motorbikes and multiple ground bases throughout the course. Ground-based terrestrial receive set ups are key for these events as the use of relay aircraft in cities such as Mumbai are often unavailable. Live video transmission from multiple city sites can be difficult due to numerous high-rise buildings, underpasses, and sometimes dense foliage. Coastal areas can be equally challenging due to low-rise structures and limited reflective surfaces. The Mumbai Marathon includes both, but despite those obstacles, Broadcast RF's setup achieved flawless video coverage.

To achieve this, a main switching hub and final decode station was established on Mumbai's Trident Hotel to enable Broadcast RF's auto-switching technology to receive signals from two other high-rise receive points along the marathon route, taking live footage from roaming camera's equipped with Domo HD transmitters and forwarded to the main OB site in Azad Maidan, where the footage was mixed and sent to air. Domo's PRORXD 8-Way Diversity RF system, a feature-rich, multi-way COFDM receiver, was central to Broadcast RF's ability ensure that transmitted video was free from distortions typically associated with fading and multipath interference.

Paul Wolff, Project Manager, Broadcast RF, said: "Despite numerous physical obstacles, with Domo's transmitter and receivers we achieved 95 percent coverage, which is remarkable given the numerous physical obstructions throughout the race route. However, the placement of the Domo receive points and the robust nature of their technology enabled us to capture far more than had previously been possible."

The Standard Chartered Mumbai Marathon is an annual event held in Mumbai, India, on the third Sunday of January. It is the largest marathon in Asia as well as the largest mass participation sporting event on the continent.
