TV TECHNOLOGY
One year after its acquisition of the wireless division of Tandberg Television, Broadcast Microwave Services (BMS) is introducing a new range of products and portable systems for television, public safety and military applications, with an emphasis on high-definition transmission.
The CT6020HD, an upgrade to the CT2020HD introduced last year, operates at 6.4 MHz and has halved latency to a single frame. Both camera-mountable transmitters, as well as the CT2200HDV, support all major resolutions and modes. Hitachi is demonstrating the CT6020HD with a Hitachi camera. The CT2200HDV, introduced last year, is distributed in the United States by JVC on its Libre Series cameras.
BMS is expecting FCC certification for its CT2430LD-S low-delay transmitter. It produces 1 W of output with just 12 W of power consumption. The tiny unit is already at work in Canada in the production of Edmonton Oilers hockey games, roving into the stands. “And they’re loving it,” said Rob Bauer, BMS director of marketing and sales, at a press conference Monday.
The company is also demonstrating its CT2436 TX. Embedded GPS technology is optional, and it operates at 4 W or 8 W in a package small enough for aircraft application. Aircraft-borne BMS technology has also been used by U.S. security agencies at major sporting events, the company said.
BMS also touts products to avoid the need for aircraft entirely. Its cellular diversity network solutions enable coverage of large-area events using overlapping cells and multiple receive sites. French production company SFP has already used the system for ironman triathlons, marathons and LeMans Series car racing. SFP is slated to use the system for bicycle race coverage at the Summer Olympics in Beijing.
Among other receiver solutions, the DR-6000 six-way receiver, with 360-degree coverage, is making headway in the reality television market, enabling the capture of multiple live camera feeds.
BMS is also introducing what it calls Modular Receiver Design, which allows users to deploy combinations of two-, four- and six-way diversity receivers in 1 RU, tailoring the system for their needs.
For urban areas with frequency congestion, the BDC2006 block downconverter offers a high sensitivity and a frequency range from 2.0 GHz to 2.7 GHz.
The 2 GHz transition is going more slowly than some had hoped. BMS stands poised to supply the digital equipment broadcasters will need. “For the most part, manufacturers are ready to go,” Bauer said.
