Nucomm, a provider of digital and analog microwave systems for the broadcast industry, common carrier, cable, government, military, and international marketplace, rolled out its new ProQ DTV IFB receiver at HD World 2008. Designed as an IFB solution for ENG users during DTV transmission, monitoring DTV signals through a DVB-ASI output, and streaming video over an IP connection to a laptop or other IP-enabled device, the ProQ DTV IFB receiver features dual UHF/VHF antennas, two advanced silicon tuners, and 6th-generation VSB demodulators.
"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," said John Payne, vice president of engineering at Nucomm, in a statement. "It also affords broadcasters the benefits of streaming DTV video over IP, which is becoming a new standard within today's industry."
The ProQ uses an MPEG-1/ 2 audio decoder capable of decoding two independent sound programs, providing up to four audio channels and using bit rates as low as 32kbps for each. When paired with a low-latency audio encoder and a DTV packet insertion, the total audio latency can be less than 80ms.
Broadcasters can select the DTV channel and audio program PIDs using the menus on the front panel LCD display or the Web interface. The receiver can also map the IFB audio channels to the XLR outputs, internal loudspeaker, or headphones. Status information, such as RF signal level/quality, DTV signal lock, and audio levels, is available through the ProQ DTV IFB receiver's Web interface and is updated in real-time on the front-panel display.
The ProQ DTV IFB receiver's firmware-based audio decoder is upgradeable and designed for advancement through the built-in Ethernet interface using a laptop computer and Web browser.
