Introduction
The
LiveGear Receiver
[
LGR-1000
] is a cellular Internet News Gathering [iNG]
Receiver and an integral part of the AirStream transmitter systems. The LiveGear
Receiver is a playout device that receives IP transmissions via the Internet and provides
a HD/SD-SDI output. Up to six transmitters [future option] can be simultaneously
received using one LGR receiver. The LGR-1000 is an effective means to receive “live”
remote iNG content and only requires an Internet connection. The AirStream transmitter
- LGR setup is accomplished using the AirStream Web interface. The LGR can also be
confi gured using the LGR Web pages.
The LiveGear receiver is typically installed at a broadcast studio or technical operations
center. Up to six bonded cellular network IP streams carrying a packetized segment
of the video transmission are received from each remote AirStream transmitters.
The bonded IP packets are aggregated to produce a single reconstructed IP stream
containing the original AirStream HD video transmission.
The IP transport stream is decoded to HD/SD-SDI and can be passed through as IP
to the studio server for distribution to customer edge devices such as smartphones,
tablets, laptops or PCs. A second licensable LiveGear IP-to-SDI decoder output is
available in the standard confi guration. A four-output expansion card [each output
licensable] is available as a factory upgrade to support a total of 6 SDI outputs. Up to
fi ve additional video transport streams can be enabled in the LGR-1000 receiver to
decode simultaneous HD/SD-SDI outputs.
The receiver also provides a duplex Interruptible Foldback [IFB] channel for monitoring
and operator cueing of remote transmitters. System confi guration of the receiver and
transmitter is controlled by an integrated Web browser GUI interface.
