Video Status
The Video Status LED idicates the current video transmission state. When lit green, the
video signal is being transmitted to the LiveGear Receiver. When lit red, the signal is not
being transmitted and an alarm state may be present [refer to Figure 31].
Destination Stream
This fi eld displays the IP Address that designates the destination for the cellular video
stream - the LGR’s IP address.
Port #
This fi eld displays the Port number, which ranges from 1 to 65,535.
Channel #
This fi eld displays the LGR Channel number, which ranges from 1 to 6.

Delay
]
The NewS
tream
transmitter has three cellular modes of operation: Low, Medium and
High delay, offering fl exibility for optimizing overall video performance as a function of
cellular link connectivity performance.
Low
- this delay mode is used in applications where there is very good 3G/4G
cellular connectivity. This setting minimizes the overall video buffer size and allows
for approximately 1 to 2 seconds of delay over the cellular network. This setting is
to be used in areas where there is intermittent or degrading cell connectivity; in
these areas there is a larger overall packet jitter which leads to an over
fl ow of the
video buffering or the loss of video frames.
Medium
- this delay mode offers the optimum video quality and an overall delay
of less than 5 seconds while minimizing the loss of video frames. This mode is to
be used with acceptable 3G/4G cellular network coverage.
High
- this delay mode uses the largest video buffer size to minimize the loss of
video frames over the cellular link. Use this mode whenever 4G coverage is not
present and 3G services are unreliable. When cell coverage is unknown, High
delay should be used initially.
Video Input
This fi eld displays the selection of Composite or SDI Cellular Video Input for the listed
preset.
