Nucomm ProQ DTV IFB Solution
Product Code: ProQDTVIFBSystem


The Nucomm ProQ DTV IFB system offers a cost-effective, highperformance approach to delivering multiple low-latency audio IFB channels over a DTV broadcast transmission.
The complete ProQ DTV IFB solution includes the ProQ LLAM (low-latency audio multiplexer) and one or more ProQ DTV IFB receivers. The ProQ LLAM is integrated into the broadcast environment, usually immediately before the STL. The ProQ system also offers an expansion system for the LLAM that simplifies the process of feeding audio cueing and remote control signals into the ProQ LLAM.
Until the ProQ system, digital IFB systems have suffered from either bit inefficiency or high latency. With the ProQ system, audio latency can be as little as 80 ms, while up to 8 separate remote cueing channels can be supported within one 250 kbps data channel.
Audio cueing channels with the ProQ LLAM are processed with an MPEG Layer1/Layer 2 audio encoder and multiplexed into a single 250 kbps data channel, with each IFB subchannel clearly identified for easy reception by the appropriate remote talent and crew.
The output of the ProQ audio encoder is multiplexed with the air channel, creating a single DTV transport stream. The ProQ LLAM also provides a fail-safe pass-through switch that ensures that the over-the-air signal is not compromised, even if the ProQ LLAM were to fail.

  • ProQ Low-Latency Audio Multiplexer
    - MPEG Layer 1/Layer 2 audio encoding
    - Encodes and multiplexes up to 8 audio cueing channels within one 250 kbps data stream (2 channels standard; optional groups of 2 channels)
    - Audio latency as low as 80 ms
    - Includes pass-through switch for broadcast transport stream
  • ProQ Receiver
    - Dual-diversity UHF/VHF silicon tuners and dual 6th generation VSB demodulators
    - MPEG Layer 1/Layer 2 audio decoding

  • Cost-effective, high-performance IFB communications system between broadcast studios and news vehicles, remote news bureaus and live sports event coverage
  • Versatile, high speed IP communications between studios and remote vehicles and locations, enabling video file transfers when used with the Nucomm Messenger IP encapsulator system
