Modulation Sciences says that it has successfully tested its system for receiving ATSC digital TV and MSI’s Digital PROciever IFB in news helicopters.
The tests of the DSPversity System were conducted at KWTV Oklahoma City in June and KIRO Seattle in July under a variety of topographical and flying conditions.
The DSPversity System comprises two key sub-systems: a four-channel ATSC diversity receiver and a unique array of antennas.
The receiver is actually four ATSC tuners, each tuned to the desired station and each with its own antenna, says MSI’s Eric Small.
“While no one tuner will deliver a valid signal for very long in a moving helicopter, chances are extremely good — several thousand to one in favor — that at any instant one of the tuners will have good data,” Small says.
Installation of the antenna array involves no penetration of the fuselage, which reduces the cost and complexity of installation and should speed the necessary certification by the Federal Aviation Administration, Small adds.
Small said there are more than 250 Digital PROceiver units delivered and operational, sending IFB via a station’s DTV signal.
Small also notes the DSPversity system can deliver reliable over-the-horizon DTV reception of DTV signals for cable and repeater applications.
