Doha’s Khalifa Stadium, which will be home to the 2006 Asian Games, has recently been fitted with PA, video screen control, broadcast cabling and distributed interactive TV systems by Qatar-based AV integration company, TechnoQ. The installation is meant to equip the venue with state-of-the-art audio and video facilities for all future events including the 2006 Asian Games. “The PA is based on a Peavey Media Matrix DSP processor and the system is a large distributed system covering the East and West grandstand seating, with additional back of house paging/announcement zones,” says Richard Hulston, senior project engineer for TechnoQ. Hulston headed the project along with project engineer, Aftab Ahmed. The system is operated from the central control room on level three with amplifier rooms located remotely at the base of the lighting arch and at level five for the main roof system. This whole system is interconnected by some 10,000 metres of cable much of which is the Belden 8424 cable. The second part of the installation was the video screen control system, which operates as a video production studio. This room is equipped with editing and character/effects generation for the creation of content for the video screens. It also has the ability to provide basic live video production facilities. The Broadcast Cabling system is the third part of the installation and comprises 48 Broadcast Connection Panels ( BCPs). These are located in all areas of the stadium from the ground floor to the interview and press rooms, the pitch level sports location, the VIP areas right to the top of the 80 metre high Lighting Arch. These run to both the video screen control room on level three and to the OB van room on the ground floor, where an extensive OB patch panel is located. This allows for cameras to be connected to both the VSCR and to the patch panels allowing provision of cabling infrastructure for broadcast providers. This broadcast cable runs a total of some 30,000 metres of Belden cable. “This cabling will provide the basic broadcast infrastructure for connecting to the OB van for live event broadcasts,” explains Hulston. “It is also connected to the video screen control room to allow production of visual content for the two large Barco LED video screens located at each end of the playing field above the grandstand seating.” The final part, the Distributed Interactive TV system, provides the feed to interactive TV points located throughout the stadium allowing individual channel selection and volume control at each of 100 plus TV outlets. “This project took approximately 18 months from design to completion,” says Hulston. “Working to unreasonable timelines has been the greatest challenge but it was well worth the effort,” he adds.
