Nucomm Brings ProQ Receiver to the Show
Nucomm is strengthening DTV signals and IP technology with its new ProQ DTV IFB receiver. The ProQ DTV IFB receiver is an IFB solution for ENG users during DTV transmission, monitoring of DTV signals through a DVB-ASI output, and streaming video over an IP connection to a laptop or other IP-enabled device. It is 5 x 1.75 x 8.5 inches and features dual UHF/VHF antennas, two advanced silicon tuners and sixth-generation VSB demodulators.

“Nucomm is always developing products to help bring more efficiency to broadcast production,” says RF Systems President Stephen Shpock. “Through our new ProQ DTV IFB receiver, users in the field can monitor the quality of DTV transmission and receive cueing signals from the studio. It also affords broadcasters the benefits of streaming DTV video over IP, which is becoming a new standard within today’s industry.”

The ProQ contains an MPEG Layer 1/Layer 2 audio decoder that is capable of decoding two independent sound programs, providing up to four audio channels and using bit rates as low as 32 kbps for each. Coupled with low-latency audio encoders and proper design of the DTV packet insertion, total audio latency can be less than 80 ms. Its audio signal outputs are outfitted on a 5-pin XLR connector.

Designed for easy and rapid user configuration, broadcasters can select the DTV channel and audio program PIDs using either the menus on the front panel LCD display or the Web interface. The ProQ can also map the IFB audio channels to either the XLR outputs, internal speaker or headphones. Status information, such as RF signal level/quality, DTV signal lock and audio levels, is available through the receiver’s Web interface and is updated in real time on the front panel LCD display.
