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. |
