Overview 3
Overview
Features
The NXL-IP55 IP Live Production Unit is an IP
transmission device that allows upstream and
downstream transmission of HD video signals, audio
signals, and various control signals with low latency of
less than one field (excluding network delays). Using the
unit allows you to configure a live production system over
a network.
Network synchronization
Devices can be synchronized via a network. Low-latency
video transmission is made possible during live
production by eliminating the need for synchronization
via a frame synchronizer.
Various transmission signals
Up to four video channels are available for transmission
with up to three in the same direction. Ten audio channels
(five pairs) are available for transmission with eight in the
same direction. Eight GPIO channels, six tally channels,
and one channel for a synchronization signal are also
available.
The content of this document applies to firmware version
V1.10.
NXL-IP55 units with different firmware version cannot
be connected together. You can check the firmware
version in [Device Information] on the [Status] page in
the Web menu.
If using an NXL-IP55 unit with a different firmware
version, contact your store or point of purchase.

of the –0.3H to +2.0H range.
In addition, the Follower for network synchronization
must meet one of the following conditions, 4to 6.
4The input phases of all the HD-SDI signals are
synchronized with the REF OUT signal, and the input
phases are synchronized within the –0.3H to +2.0H
range.
5The HD-SDI input signals are all synchronized with
matching phases, but the input phases are outside of
the –0.3H to +2.0H range.
6Under condition 4or condition 5, only one of the
inputs is not synchronized or its input phase is outside
of the –0.3H to +2.0H range.
Settings for condition 1
• Set [Reference in] > [V Phase] on the [I/O] page to 0.
• Set [Frame Synchronizer] on the [Structure] page to
[OFF].
Settings for condition 2
• Adjust input equipment, and configure the phases so
that they meet condition 1. Alternatively, configure
[Reference in] > [V Phase] on the [I/O] page to match
the amount of shift and meet condition 1.
• Set [Frame Synchronizer] on the [Structure] page to
[OFF].
Settings for condition 3
• Refer to the settings for conditions 1and 2, and
configure the phase.
• Input the unsynchronized signal to SDI IN connector 1,
and set [Frame Synchronizer] > [SDI in 1] on the
[Structure] page to [ON].
Settings for condition 4
• Set [Reference out] > [V Phase] on the [I/O] page to 0.
• Set [Frame Synchronizer] on the [Structure] page to
[OFF].
Settings for condition 5
• Adjust input equipment, and configure the phases so
that they meet condition 4. Alternatively, adjust the
phase of the input equipment using [Reference out] >
[V Phase] on the [I/O] page and meet condition 4.
• Set [Frame Synchronizer] on the [Structure] page to
[OFF].
Settings for condition 6
• Refer to the settings for conditions 4and 5, and
configure the phase.
• Input the unsynchronized signal to SDI IN connector 1,
and set [Frame Synchronizer] > [SDI in 1] on the
[Structure] page to [ON].
Delays will occur if you use a frame synchronizer.
Output phases
When using [Reference in] > [V Phase] and [Reference
out] > [V Phase] set to 0 on the [I/O] page of the web
menu as a basis, the output phase of the unit’s HD-SDI
signal will be as follows.
When [Main Video Direction] is [Receiver]
A signal that matches the REF IN signal will be output.
When [Main Video Direction] is [Transmitter]
The signal will be delayed in relation to the REF OUT
signal. The amount of delay will increase the more the
network latency increases.
If you want to synchronize the output phase of the
Follower with a different synchronization signal, input
that signal to the REF IN connector, and set [Frame
Synchronizer] > [ALL] on the [Structure] page of the web
menu to [ON].
Packet loss Number of received video packet errors
and number of packets lost during the
test, and the total number of errors and
lost packets since the unit was turned on.
Pass: Errors and packet loss did not
occur during the test, and the unit
meets the transmission requirements.
Failed: Packet loss occurred during the
test, or invalid packets that could not
be corrected via the unit’s error
correction function were received.
(Invalid packets are counted as lost
packets.)
Throughput
(informative)
Bit rate of the video packets received
during the test (reference value), and the
total byte count of the received packets.
Pass: The video bit rate during the test
was equal to or higher than the bit
rate of the test video.
Failed: The video bit rate during the test
was lower than the bit rate of the test
video.
