Brazil's TV Globo International (TVGI) undertook the first live HD broadcast of the famed Rio de Janeiro and São Paulo annual Carnival using microwave technology from RF Central. Channel 18 in São Paulo was able to deliver 32 hours of realtime coverage.

Although TVGI has taped the event in HD for the past four years, an array of RF Central equipment allowed the event to be broadcast live in HD this year. Seven RFX-RX6-II six-way diversity receivers were used for wireless camera reception in both SD and HD as well as at TVGI's HD helicopter receiver site.

In addition, two TVGI wireless cameras were outfitted with RFX-CMT-II HD rack-mounted camera transmitters, and one RFX-PHT-II HD portable digital transmitter was attached to the station's helicopter for aerial shots. An extra PHT-II was used alongside a fixed RF camera for ground coverage.
