About the VN-Matrix 300
The Extron® range of VN-Matrix™ 300 video encoders/decoders (VNC 300 codecs) distribute
digital SD and HDTV broadcast quality video across an IP network. The VN-Matrix 300
provides the bridge between digital video devices and IP-based networks. This user guide
describes the operation of a VN-Matrix 300 series device tted with v.4.5g rmware or later.
Video signals connected to a VN-Matrix 300 encoder are compressed into a TCP or RTP data
stream for transport across a local area or wide area network. At the far end of the network
another VN-Matrix 300 unit decodes the compressed stream back into the original video
signal format.
Ancillary (primarily audio data associated with the original video signal) is preserved in an
uncompressed form and is transported across the network alongside the video signal.
Functional Overview
The VNC 300 codec can be congured to operate in one of two modes, as an:
z Encoder — to encode a source and stream it across a network
z Decoder — to decode a VN-Matrix 300 data stream from a network
Therefore, any VN-Matrix 300 system will comprise at least two devices, one congured as
an encoder and the other as a decoder. Multiple encoders and decoders can co-exist on the
same network.
On a given network, any decoder can display the source provided by any encoder.
NOTE: The VN-Matrix 300 is also available as a decoder only device (VND 300). In this
case, details included here relating to the encoding of digital video signals are
not relevant.
VN-Matrix 300 • Introduction 1

Signal Compatibility — Video
The VN-Matrix 300 is supplied in one of three options, based on the type of digital video
transport and video resolutions that it is intended to support.

10bit, 4:2:2, YCrCb, YCrCb
Supported Video modes
10 bit, 4:2:2. YCrCb
The VN-Matrix 300 incorporates advanced image acquisition circuitry which can auto-detect
the format of the connected signal without the need for any additional setup. Input sources
are encoded and decoded at their native resolution and format.
Signal Compatibility — Audio
The VN-Matrix 300 range of codecs support the transport of embedded audio data as
described by the following SMPTE standards.
z SMPTE 299M: 24 bit digital audio
z SMPTE 272M-A: 20 bit digital audio
VNC 300 configured as an Encoder
The source signal is connected to the input BNC of the VNC 300. A reclocked loop through
connection is provided for an external local monitor. In addition, a second loop through is
available that includes an overlay function that may be used for identification purposes.
VNC 300 configured as a Decoder
The decoded video signal is available on the output BNC. The loop through connector is not
active.
NOTE: The input connector BNC on the decoder may be used to connect to a digital
studio genlock signal.
Unit Setup and Configuration
Low level communications setup of the VNC 300 or VND 300 is achieved using a serial data
link to the COM1 port. This interface provides for configuration of the network settings for
each unit and is undertaken during commissioning.
High level conguration is achieved via the network using the Integrated Web Management
System.
There is no need for the VN-Matrix 300 units to be congured for a specic source type. The
VNC 300 or VND 300 automatically identies the source format of the signal connected to
the encoder. The decoded image is presented in exactly the same format.
Conguration of the system specic parameters is made via the Integrated Web
Management provided by the controller.

System Control
Integrated Web Management System
Additional Control Features
Network Requirements
The VN-Matrix 300 incorporates an integrated web management system (referred to in
this manual as the web interface). This allows any VN-Matrix 300 unit on a network to be
congured via a Windows®-based PC (on the same network), using a standard web browser
(such as Mozilla FireFox® or Internet Explorer®).
This interface provides for full control of the VN-Matrix 300 feature set.
One VN-Matrix 300 unit in the system is designated as a controller. This unit acts as a server
for the web interface and holds a record of the conguration for all VN-Matrix 300 devices
on the network. The controller manages the communications to all VN-Matrix 300 devices.
Any VN-Matrix 300 unit, whether it is congured as an encoder or decoder, can be used as a
controller.
Remote Control
RS-232 serial data can be routed between selected VN-Matrix 300 units using the COM2
port, for example to provide remote control of an external device.
The VN-Matrix 300 uses highly efcient compression algorithms to minimize the amount of
data needed to be transported across the network.
It is, however, crucial to the effective operation of VN-Matrix 300 that sufcient data
throughput can be achieved, especially where multiple sources are being encoded.
The efficiency of a network will be directly affected by the speed and configuration of each
element within its infrastructure, such as switchers and routers. The VN-Matrix 300 will
achieve optimum transmission results over a dedicated 1 Gbps network (Gigabit Ethernet).

Data Transport Methods
Source (video) data from a VN-Matrix 300 Encoder can be distributed to multiple displays/
decoders (one-to-many) or to a single display/decoder (point-to-point).
Video data is transported from the source (encoder) to the display (decoder) using one of
three methods:
z Multicast RTP
z Unicast RTP
z Unicast TCP
A description of each method, together with its advantages and disadvantages, can be
found on the following pages.
VN-Matrix 300 • Introduction 4

Multicast RTP
IP Rx (a)
This transport method uses a real-time variation of UDP (User Datagram Protocol), called

Figure 2. Using Multicast RTP to Display a Source on Numerous Displays
The source encoder uses RTP to send data to a multicast group. RTP provides very low
latency which is important for video transport. The RTP protocol compensates for jitter and
any breaks in the sequence of data during the transfer over an IP network.
This is the recommended transport method for real time video and audio data over an
IP network. However, because RTP is a connection-less protocol, data delivery is not
guaranteed. Where data packets are lost (such as due to excessive network traffic) the
VN-Matrix 300 carefully manages the data stream to minimize any image disruption.
VN-Matrix 300 • Introduction 5
Page 12
Unicast RTP
Like Multicast RTP, this method uses a real-time variation of UDP protocol, called RTP. This
method can be used where the network infrastructure does not support multicast traffic.
Typically this should be used as a point-to-point configuration (that is: single source to single
display) but it can also be used for up to four displays.

RTP provides very low latency which is important for video transport. The RTP protocol
compensates for jitter and any breaks in the sequence of data during the transfer over an IP
network.
However, because RTP is a connection-less protocol, data delivery is not guaranteed. Where
data packets are lost (for example: due to excessive network trafc) the VN-Matrix 300
carefully manages the data stream to minimize any image disruption.

NOTE: Multiple decoder connections are theoretically possible using this method but
NOT recommended. Each additional connection creates extra loading on the
encoder CPU which ultimately results in poor display performance. In addition,
multiple TCP streams carrying the same source data is an inefficient use of
network bandwidth.

Installation and Basic Setup Procedures
This section describes basic installation and setup procedures, including:
z Choosing a Suitable Location
z Environmental Requirements
z Rack Mount Requirements
z Mains Power Connection
z Mains Power Cord
z Accessories
z Setup Procedure
z Network Connections
Choosing a Suitable Location
The VN-Matrix 300 is designed to be used either as a free-standing unit or to be mounted in
a 19-inch equipment rack using the optional kits available.
CAUTION: Whichever installation method you choose there are certain environmental
requirements, detailed on the following pages, which must be observed in
order to ensure safe and reliable operation.
Environmental Requirements
CAUTION: The criteria on this page must be observed for all installations of the
VN-Matrix 300, whether free-standing or rack-mounted.
Orientation
The VN-Matrix 300 is designed to be used free-standing on a stable, horizontal surface. It
can, however, be used in any orientation subject to the necessary ventilation requirements.
VN-Matrix 300 • Installation and Basic Setup Procedures 11
Page 18
Temperature
DO NOT install or operate the VN-Matrix 300 in an area where the ambient temperature
exceeds 35°C (95°F) or falls below 5°C (35°F).
Remember that, as with all electronic equipment, the VN-Matrix 300 and its associated PSU
also produces heat which may affect the ambient temperature.
After the VN-Matrix 300 has been in use for a period of time, the external casing may
become slightly warm to the touch. Ensure that any adjacent surfaces will not be affected by
the heat.
Ventilation
DO NOT obstruct the ventilation grills during use. The VN-Matrix 300 has an integral
forced-air cooling system. A fan draws air in through the grille in the front panel and expels
warmed air through the grilles in the back panel. The fan speed is controlled automatically
by an internal temperature sensor. The fan may, therefore, appear to run faster as the unit
warms up or if the ambient temperature is increased.
A self-resetting thermal cut-out will shutdown the VN-Matrix 300 if the temperature exceeds
design limits.
Humidity and Water
DO NOT install or operate the VN-Matrix 300 in an area in which the ambient relative
humidity exceeds 85% or in an area that is prone to condensation.
DO NOT install or operate the VN-Matrix 300 near water or in a location which may be
prone to water seepage — the VN-Matrix 300 is not waterproof.
Rack Mount Requirements
CAUTION: For rack-mounted installations, the following criteria must be observed.
Mounting and Support
Ventilation
Power Supply
ALWAYS use the special rack-mount kits (available separately) to secure the VN-Matrix 300.
Full details on using the kit are included with the kit. It will be necessary to remove the four
feet before rack mounting.
DO NOT stand other units directly on top of the VN-Matrix 300 when it is rack-mounted as
this will place excessive strain on the mounting brackets.
ALWAYS ensure that the rack enclosure is adequately ventilated. Sufcient airow must be
achieved (by convection or forced-air cooling) to satisfy the ventilation requirements of all
items of equipment installed within the rack.
No additional ventilation gap is required above or below the VN-Matrix 300 and adjacent
surfaces or equipment.
ALWAYS ensure that the mains power supply is of the correct voltage and frequency for all
equipment within the rack, and that it has a good ground/earth connection.
Where a power strip (mains distribution batten) is used (of either a hard-wired or plug and
socket type), always ensure that the current rating of both the power strip and the supply is
sufficient for all equipment within the rack.
VN-Matrix 300 • Installation and Basic Setup Procedures 12
Page 19
Mains Power Connection (via PSU)
The VN-Matrix 300 must be powered from a 12 Volt DC regulated supply. A suitable
mains-operated power supply unit (PSU) is provided. The mains connection details that
follow relate to the PSU.
CAUTION: Never connect the VN-Matrix 300 directly to the mains.
To ensure CE compliance ALWAYS use the PSU provided. If a backup or
replacement PSU is required, always use an Extron approved PSU.
Supply Requirements (for PSU)
CAUTION: ALWAYS observe the following instructions to ensure safe and reliable
operation of the PSU.
ALWAYS ensure that the mains supply voltage is single phase only and is within the
permitted range:
z 100 – 240 V AC (0.45 A Max.) 50 – 60 Hz.
NEVER connect the PSU to a DC supply.
DO NOT allow the mains power point to be overloaded. This is particularly important to
check when powering several items of equipment from a single power point (such as within
rack-mounted installations).
WARNINGS: This equipment must be grounded / earthed.
To avoid the possible risk of electric shock or product damage due to
condensation, ALWAYS allow the PSU to become acclimatized to ambient
temperature and humidity for at least thirty minutes BEFORE switching on.
This is particularly important when moving the unit from a cold to a warm
location.
Mains Power Cord (for PSU)
Power-up Procedure
The mains PSU is equipped with a 3-pin (male) type mains connector which requires a power
cord tted with a corresponding 3-pin IEC320 (female) connector.
The type of power cord that is supplied will be appropriate for use in your country:
WARNING: Do not allow anything to rest on the mains power cord.
You must always ensure that the VN-Matrix 300 is powered-up at the same time as the
source computer or slightly before.
VN-Matrix 300 • Installation and Basic Setup Procedures 13
Page 20
Fitting a Mains Plug
If you are fitting a plug to the unterminated power cord (or replacing an existing plug), you
must fit a plug that:
z Is rated for use with mains voltage
z Is equipped with a grounding pin/connection
z Complies with any applicable National or Local electrical regulations.
z Is tted with a correctly rated fuse (applicable to UK-style plugs only, see page 13)
WARNING: Never attempt to fit or use a plug without a ground or earth pin/

WARNING: If you are unsure of the connections, or if the markings in your plug do not
match those given above, CONSULT A QUALIFIED ELECTRICIAN.
NOTE: The PSU is double-insulated and does not require an earth/ground connection.
However, the earth cable of the mains lead must be connected in the plug.
External Supply Protection
CAUTION: The mains power cord supplied with this product is rated at 10A maximum
and must be protected from overload by an external fuse or circuit breaker.
Fused Plugs (UK-style)
If the power cord is tted with a UK-style BS1363 3-pin plug (that is, with provision for an
internal fuse), then it must be tted with a BS1362 ASTA approved 1 inch cartridge fuse.
This fuse must be rated at a maximum of 10A/250V. Since the current draw of the PSU is
less than 1A, a fuse of a lower rating not less that 3A/250V may be used.
WARNING: Never attempt to fit a fuse or circuit breaker of a higher maximum rating
than shown above.

Network (NIC) Connections
All network connections are made at the rear panel of the VN-Matrix 300.
CAUTION: Do not proceed with connecting VN-Matrix 300 to an existing network until
it is correctly configured using the Low level configuration procedure.
Incorrect connection or configuration may cause disruption to other
network users.
By default this is set to 5432, this may be changed if required.
Note that all VN-Matrix 300 units MUST have the same port
number assigned.
By default this is set to 80, this may be changed if required.
Note that the browser in use must use the same port number.
Any changes made are only activated after a reboot of the
VN-Matrix 300 unit.
NOTE: Typing reboot at the hyperterminal
cursor will also reset the unit.
Typically, the VN-Matrix 300 will connect to convenient network point on an existing inhouse network. Use the correct cable type for your chosen network.
Single Network Connection
The VN-Matrix 300 may be congured to run on a single physical network port (1 or 2). In
this configuration all data (image, ancillary and control including monitoring) is transported
over a single physical link.
The VN-Matrix 300 may be used over both switched (single segment) and routed
(multi-segment) networks.
Dual Network Connection
If required, both network connections may be used. In this configuration image and ancillary
data is transported on one connection whilst the other network port is used for monitoring
and or management functions.
System Control Data
System control is managed by the VN-Matrix 300 that has been designated as the controller.
Any changes made in the interface are sent to the affected VN-Matrix 300 device from the
controller. The control information between the controller and any other VN-Matrix 300 unit
in the system is sent via the network that has been assigned to the controller.

VN-Matrix 300 Web Interface
Once all VN-Matrix 300 devices have been correctly set-up for and connected to a network,
any further system conguration is achieved via the VN-Matrix 300 web interface. This
comprises a number of pages which provide access to various system parameters.
The web interface is served up by the VN-Matrix 300 device that was designated as the
controller during the network set-up procedure. It can be viewed by any up-to-date web
browser, running on a PC that is connected to the same network as the VN-Matrix 300
devices.
Suitable browsers include (but are not necessarily limited to):
z Firefox/Mozilla (v1.3 and above)
Firefox is the recommended browser for use with the VN-Matrix 300 product family
z Internet Explorer (v6 and above)
NOTE: Whatever browser is used, it must be congured to accept cookies and be
JavaScript-enabled.
VN-Matrix 300 • System Conguration 26
Page 33
Start Up and Login Procedure
The IP address of the controller is entered into the address bar of the browser in the normal
way.
Figure 13. Entering the IP Address
In the example above, the IP address of the controller is 192.168.0.101.
NOTE: The IP address of the controller in your system will be different.
The login screen will be displayed in the browser (see gure 14).
Login Screen — User Accounts
VN-Matrix 300 has two user accounts:
z admin — which allows full read/write access to all setup parameters,
z public — which allows read only access to setup parameters.
Initially the password for both accounts is the same as the user name (that is, the account
name). It is recommended that these are changed once commissioning is complete.
For commissioning use the admin account and click LOGIN.

Figure 20. Bandwidth Page
The Bandwidth page provides for the control of the spatial and temporal compression
settings for the encoded source.
The available controls are arranged as two main groups:
z Bandwidth Management (Standard control) — Provides a simple interface used to
congure a subset of the VN-Matrix 300 compression toolset.
z Advanced settings — Provides (advanced) control of the complete VN-Matrix 300
compression toolset. To hide this area, click the Standard button in the Bandwidth
Management control section.
NOTE: When hiding the Advanced control area section, default settings are applied
to some of the controls. These settings remain in force while the Standard
area controls are in use and will cancel any changes that were made
previously.

Bandwidth Management — Standard Control
Figure 21. Standard Control Area
The Standard control area provides a user with a quick configuration method for the
VN-Matrix 300 encoder.
Statistics for any active streams currently running from the encoder are provided in the
Streams information area.
Conguration for the encoder is made via 3 entries:
z Control Mode
z Image Quality
z Bit rate.
Control Mode
The Control Mode list is a set of 6 modes that are designed to manage the encoded image
data stream by applying different spatial and temporal compression schemes.
NOTE: These control modes are also accessible in the Advanced settings control
area
.
z None — In this mode the compression scheme maintains a constant image quality. The
bit rate will vary dependant on the content. Slowly moving or static image content will
have a lower bit rate than fast moving image sequences. There is no bit rate limiting in
this mode.
z Peak Flow — In this mode, the spatial image quality is held constant. However, a bit
rate limit is applied and maintained by controlling the frame update rate whenever this
limit is exceeded.
z PBR-F — This is a Peak bit rate mode. The spatial quality is held constant until the bit
rate limit is exceeded. At this point, additional spatial compression is applied to keep the
bit rate at the specified limit.
If the content is such that it is not possible to maintain the bit rate limit using only
spatial compression then a different control mode should be chosen or the bit rate limit
should be increased.
z PBR-F (FD) — This mode is as for PBR-F with the addition of dynamic frame rate
management if the spatial compression is insufficient to maintain the bit rate limit.
VN-Matrix 300 • System Conguration 35
Page 42
Image Quality
The Image Quality controls the spatial compression. A setting of 4 provides a visually lossless
image. A higher setting results in higher compression whilst a lower setting applies a lower
level of compression.
Changes made to this setting will result in a corresponding change in the bit rate for the
encoded stream.
Bit Rate
Enter a value up to a maximum of 300 Mbs to set the limit for the aggregate (total) bit rate
for all data.
z Image data
z Audio
z Ancillary
This control is not available when the Control mode is set to NONE.

Click the Advanced button in the Bandwidth (simple) control area described in the previous
pages to access this sectopm.
The controls in this area provide access to the complete set of image quality and bit rate
tools for the VN-Matrix 300 encoder.
The controls are divided into to two main categories:
z Video Quality

Some of the controls that are available in the simple control interface described above are
also present in this area. Where controls are duplicated, the settings will track.
VN-Matrix 300 • System Conguration 36

Video Quality Management
Spatial Compression settings
Figure 23. Spatial Compression Settings
The level of spatial compression is set using the Luminance and Chrominance control.
These controls are normally locked, with an optimal offset of 2 units between them.
A Luminance value of 0 provides the minimum spatial compression; a Luminance value of
10 provides the maximum spatial compression.
If required, the Chrominance compression may be set independently by unchecking the
Lock box.
A spatial compression setting of 4/6 will provide visually lossless compression for HD content.
NOTE: By default, the Luminance and Chrominance offset is set to 2 whenever the
simple (standard) management scheme is selected.
Temporal Compression settings
Temporal compression may be applied by selecting the Temporal check box.
By default, this option should always be selected.
Temporal compression causes data to be transferred only when a change occurs between frames.
Using the Threshold setting
The Threshold setting (see figure 23) modifies the detection point of the temporal
compression algorithm. A value of 0 results in all changes between frames being sent.
As the threshold value is increased, only changes above a certain level are sent, thus
reducing the bit rate. This control is used to compensate for image sources that have a level
of noise in them. In general, there is always a certain amount of noise in any source that
is produced by an analogue method. By applying a threshold this noise can effectively be
ignored by the PURE3 compression engine, resulting in a lower transmitted bit rate.
As a general rule, always set this to a 1 for a camera originated image.
When to use the Chroma setting
The Chroma setting adapts the temporal compression to take note of the chroma changes in
an image. When enabled, note that chroma thresholding will increase the bit rate.
This setting should be selected (on) for video sources.
Refresh Rate
Refresh rate controls how frequently the non-changing parts of the screen are updated
when temporal compression mode is enabled. This is useful when connecting new displays
to a Mb source and to fill in gaps in the data when using a lossy network transport such as
RTP. A value of 1 refreshes the screen in one second, a value of 0.1 refreshes the screen 10
times per second. A value of 0 disables the refresh.
VN-Matrix 300 • System Conguration 37
Page 44
Bandwidth Management
The Bandwidth management section provides a method to set a maximum bit rate for the
encoded stream. It duplicates the Control mode settings already described in the Standard
Control
Figure 24. Bandwidth Management Section
Control Mode: Manual Frame drop
In this mode, the spatial image quality is held constant. However, a bit rate limit is applied
and maintained by controlling the frame update rate whenever this limit is exceeded. The
frame rate is managed by setting a value for the Frame Drop Percentage. This is the
percentage of frames that are dropped whenever the bit rate limit is exceeded.
Control Mode: Shared Flow rate
This mode is the same as the Peak flow rate but the bit rate control is applied to the
aggregate value for all streams from the encoder, as would be the case if multiple
(maximum 4) Unicast streams are chosen as the data transport method.
area (already described above) but includes two additional modes of control.
Streams Panel
The streams panel provides statistics on all of the active connections running on the encoder.

ANC Panel
Provides for control and configuration of the ancillary data channels.
Selecting the Audio group
There are 16 audio channels present in the SDI/HDSDI/3G SDI video transport. These are
arranged in 4 groups each of 4 channels. The VN-Matrix 300 units can transport 1 group
(4 audio channels). The required audio group is selected here. The groups are presented as
channel pairs as described below.
z Channel pair 1: Group 1, channels 1&2
z Channel pair 2: Group 1, channels 3&4.
z Channel pair 3: Group 2, channels 1&2
z Channel pair 4: Group 2, channels 3&4.
z Channel pair 5: Group 3, channels 1&2
z Channel pair 6: Group 3, channels 3&4.
z Channel pair 7: Group 4, channels 1&2
z Channel pair 8: Group 4, channels 3&4.
The indicator to the right of the list showing each channel pair is green if that audio group is
present in the SDI source.
Selecting either of the check boxes associated with a group will automatically enable both of
the channel pairs in that group. It is not possible to select fewer than 2 channel pairs.
FEC Panel
Forward error correction may be applied to the ancillary data. This protects against packet
loss when the ancillary data is transported across a network.
Forward Error Correction
Forward error correction may be applied to the Ancillary data to protect against errors
caused by packet loss when the data is transported over a network. Forward Error Correction
(FEC) enables the decoder to recreate data that has been lost or corrupted without the need
for retransmission. The FEC data is sent separate from the image and ancillary data.
The level of FEC can be set to protect against different levels of data loss. This produces a
corresponding change in the amount of data that is transported and thus, the bit rate is
increased or decreased in proportion to the amount of FEC applied.
PRO-MPEG COP3
The error correction scheme employed on the VN-Matrix 300 product range is implemented
using the recommendations of PRO-MPEG COP3.
Row and Column FEC
The FEC may be applied as either column or column and row.
z Column FEC is used to protect against burst packet losses, providing that the burst of
packet losses are not in the same row. Column FEC is known as 1D (dimension) FEC, as
correction data is only calculated on one dimension.
z Row FEC is used to protect against the loss of a single packet. It is the simplest method
of protection and results in the lowest overhead in terms of bit rate and latency.
However, it is not able to handle consecutive (burst) burst packet loss.
VN-Matrix 300 • System Conguration 40
Page 47
By using both FEC methods together, 2 dimensional FEC, the combined effect can protect
against more loss permutations than either scheme used in isolation.
FEC works by adding additional data to the stream. Using this data it is possible for the
decoder to detect and reconstruct any lost packets.

The diagram to the left shows the FEC scheme
applied to a 4 (column) x 5 (row) structure. Note
that this adds 5 row FEC packets and 4 column FEC
packets to every 20 data packets. This scheme can
protect for burst packet losses up 5 packets long.

for using the FR2 FEC packet.
It is not possible to correct packets 14, 15, and 16
using the row FEC (FR4) as too much data is missing.
To correct these packets, the column FEC data is
used. Packets 15 and 16 may be corrected using FC3
and FC4 column FEC packets. To correct packet 14,
packet 6 must rst be corrected using the row FEC.
After this, the column FEC may be used to correct
packet 14.
Setting the FEC value
The values that are set in the FEC row and column drop down lists will depend on the quality
of the network link that is in use.
From the diagrams above it can be seen that the FEC data can add a large overhead to the
overall bit rate that is transported over the network. Therefore certain settings, whilst they
may provide a high level of reliability, will be inefficient. Settings that add little overhead may
not provide a sufcient level of protection on networks with a poor QoS.
The recommended setting is 5,5. This setting should be used as the starting point for the
error correction for the audio transport and provides rugged operation on uncorrected IP
networks.
NOTE: • FEC is ONLY applied to the ancillary data channel. It is NOT applied to the
video channel.
• FEC is only effective for RTP transports. It should not be used for TCP
transport.
Error injection rate
This setting should be left at 0. It used for test purposes only and is used to drop packets
articially in order to test the effectiveness of the FEC scheme.

Decoder Videoport Panel
The top panel of the videoport (decoder) configuration page provides access to the following
features:
z Name — This may be changed to a user specific value. This is the name that is
displayed in the device list page.
z Nodata splash — Enables the display of a splash screen when the display device
detects a break in the input data stream. When this control is disabled the last decoded
frame is displayed.
z Active format — This value reports the currently selected output mode. The reported
mode will be the same as the source type. If no source is available then a the splash
screen resolution is reported.
Decoder Streams Panel
The lower panel provides for stream selection and bit rate monitoring.
Figure 31. Decoder Streams Panel
Decoder — Source stream selection
Figure 32. Active Source Stream
The active source (streams) that are available may be viewed in a drop down list under the
Source heading in the lower panel.
The available streams are listed by their device name (these may be user defined by renaming
the appropriate encoder device).
The type of connection that is to be established between an encoder and decoder is defined
by picking the stream type from this drop down list.
Stream Type —_tcp
A unicast TCP stream, used for guaranteed delivery point to point connections.
Stream Type — rtp unicast
A unicast UDP stream, used for best effort point to point connections. This type of
connection is replaced by the _rtp(m) type if a multicast stream has been configured at the
corresponding encoder.
VN-Matrix 300 • System Conguration 46
Page 53
Stream Type —_rtp MULTICAST
A multicast UDP stream, used for best effort point to multi point delivery. Note that
this stream type is only available when a multicast stream has been configured at the
corresponding encoder.
Decoder — Enabling audio streams
Transport of the audio content (the audio stream) associated with the selected video stream
may be enabled by selecting the Audio check box under the Audio heading.
Use the update button to apply the setting.
The selected audio stream will be listed adjacent to the audio heading in the bandwidth list.

Decoder — Enabling FEC for audio streams
Forward error correction (FEC) for the selected audio stream may be enabled by selecting the
FEC check box under the FEC heading.
Select the the update button to apply the setting.
The associated FEC stream will be listed adjacent to the colfec and rowfec headings in the
bandwidth list.
Figure 34. FEC Stream
NOTES: • FEC data is only sent from an encoder when it is enabled for processing by a
decoder.
• FEC data is only sent for the audio stream.

Decoder — Bit Rate and Stream Statistics
The bit rate and statistics for each of the stream types (video, audio and FEC) may be
monitored.
NOTE: The bit rate statistic reported here applies to whichever stream type is being
monitored. This is different to the bit rate statistics reported by the encoder,
which is for the total of all stream types.
Select the stream that is to be monitored by selecting the appropriate entry in the
bandwidth list.
The following example is specic to the video data. Note that the scheme for audio and FEC
data is the same.
Bandwidth page — stream statistics
Figure 35. Stream Statistics on Bandwidth Page
z Source — Reports the currently select stream.
z rtp destination — Reports the IP destination address and port for the current stream.
When connecting using RTP this will be either a multicast group address or, for RTP
unicast, the IP address of the decoder. When connecting using TCP, this eld will be
empty.
z rtp source — Reports the multicast group address that reception statistics will be
reported to. In RTP unicast and TCP modes this reports the IP address of the encoder.
z Playback Delay — This defines the playback delay. The playback delay is the sum of
the transit time in the network and the time spent in the input buffer of the decoder.
This setting may me modified by the user.
z Setting the Playback Delay too small results in the playback image jumping as
network loading changes.
z Setting the Playback Delay too large increases the image latency and may result
in internal buffer overflow on high bandwidth data streams. This causes a jumpy
screen update and screen flashing.
The Playback Delay setting should be set to a value between 0.1 and 0.2 seconds.
VN-Matrix 300 • System Conguration 48
Page 55
Bit rate and network statistics for the current stream are reported in a tabular form.
z The total column contains counts for the history of the stream.
z The window1 and window2 columns contain counts over user programmable
intervals.
z Megabits/sec — The bit rate received from the current data source.
NOTE: The reported bit rate is for the video stream only. Statistics are available
for Audio and FEC on page 45.
z Packets/sec — The number of data packets per second received from the source.
z Dropped packets — The number of data packets dropped during the associated
interval time. This will always be 0 for TCP streams.
Dropped packets will be counted when using RTP streams on busy networks.
z Interval time — The time over which the previous counts are averaged.
The total column assumes an interval time of infinity. The remaining two times are user
programmable in seconds.
Device Page — Peripherals
Serial Port Control
Bi-directional serial communications (RS-232) can be achieved between any VN-Matrix 300
units on a network.
Serial data is sent independently of the other streams on the network and it is not necessary
to have a direct encoder to decoder relationship.
Pass-through Control Mode
In this mode, serial data is passed from one VN-Matrix 300 device to another. Data ow
is fully bi-directional and is independent of whether the VN-Matrix 300 is an encoder or
decoder. Thus control of external equipment is supported.
Figure 36. Pass-through Control
A single VN-Matrix 300 device is designated the server. One or more VN-Matrix 300 devices
are then configured as clients.
VN-Matrix 300 • System Conguration 49
Page 56
Data input to the server is sent to all clients simultaneously. Data received at a client is sent
to the server. Simultaneous data transfers are processed on a first in first out basis.
Any number of pass-through groups may exist on the same network.
Communication may only take place between a client and a server; it is not possible to
communicate from client to client.

Firmware, Licensing Upgrades and User Accounts
This section describes upgrading device firmware and clock management.
Upgrading Device Firmware
From time to time Extron may issue rmware upgrades for VN-Matrix 300 in order to make
new functionality available. Details of the latest firmware release will be published on our
website, www.extron.com.
Upgrades are supplied in a single le, named in the format upgrade_verx.x.tar where
verx.x is the version number. Before you start you will need to copy the upgrade le on to
the computer that you use to access the VN-Matrix 300 controller.
The update process is split into the following stages:
Stage Function Summary Performed On
Upload Copy the upgrade file from the control
PC to a temporary storage area on the
VN-Matrix 300 Controller
Prepare Unpack and copy the new rmware (from
the controller) into the VN-Matrix 300
alternate flash memory.
Activate Reboot the VN-Matrix 300 to start using
the new firmware. This is a temporary
mode that allows you to test the new
firmware. If you encounter any problems
you can back out of this mode and return
to the previous firmware version.
Commit Reboot the VN-Matrix 300 to start using
the new firmware permanently.
All stages of the upgrade process are carried out using the web interface. It is recommended
that all VN-Matrix 300 units in the same system are upgraded to the same rmware version
to ensure full compatibility.

NOTES: z Performing the Activate function on the controller will cause the device
to reboot and as a result the upgrade file (in the temporary storage are) will
be erased. It is recommended, therefore, that you PREPARE all devices
first, after which the upgrade file will no longer be needed. Then perform the
Activate function on each device, commencing with the controller.
• The Activate function must be performed on the controller device first, such
that the new firmware is in control of upgrading the remaining devices.
• When performing Activate or Commit on the controller, the device will
reboot.
• This will cause temporary loss of the web interface, since this is provided by
the controller.
• Wait for 30 seconds to allow the device time to reboot, then refresh the
browser.

Alarm Type
This drop down lists the available alarm error conditions for all units. Alarm error conditions
are divided into two broad categories
z Alarm errors that occur on an Encoder
z Alarm errors that occur on a Decoder
In addition there is one alarm error that only occurs on the device that is configured as the
system controller.
Alarm Source
Alarm lters may be set for either a single, specic unit or for all VN-Matrix 300 devices in
the system.
Alarm Severity
Alarms may be set to one of three severities.
Alarm Severity Description
Critical
Warning When triggered, a warning alarm will result in the trafc light indicator
None
When triggered, a critical alarm illuminates the red LED on the front
panel of the affected unit. In addition, the normally open contacts of the
relay accessed via the COMM 2 connector will be closed.
The traffic light indicator for the device (Device list) will be shown in red.
for the device (device list) showing in amber.
A setting of None effectively filters the alarm condition. The alarm will
still appear in the alarms list but it will not affect any colored indicators.

Overview — SNMP
The VN-Matrix 300 system has the ability to report alarm events via an SNMP trap, providing
simple integration with Network management systems (NMS).
When communicating using SNMP the VN-Matrix 300 complies with the requirements of
SNMP v3.
When generating SNMP traps the VN-Matrix 300 complies with the requirements of SNMPv1
and SNMPv2C.
Using SNMP — Password
The SNMP password is the same as the administrator password. By default this is set to
admin.
It is necessary to enter the administrator password in the accounts a page before SNMP can
be used. This process must be carried out for each of the following circumstances:
z When rst using the system
z After a firmware upgrade to the system
A password for SNMPv3 is required to be 8 characters long.
z If the administrator password is less than 8 characters in length then the remaining
z If the administrator password is longer than 8 characters then the value is
characters are packed as follows:
admin becomes adminadm
concatenated:
concatenate becomes concaten
SNMP Trap Version
The VN-Matrix 300 supports both version 1 and version 2 SNMP traps (SNMPv1 and
SNMPv2c).
SNMP Community
The SNMP Community value acts as a password. It is used to authenticate messages
between the VN-Matrix 300 system and the NMS. By default the Community string is set to
public. The Community string must match that in use by the NMS; if not then it may not be
possible to manage the VN-Matrix 300 device.
SNMP Trap Destinations
The Filter Settings dialogue in the Alarm Logs page is used to add and remove destination
IP addresses for NMS servers.
Figure 49. Filter Settings Dialog Box
The IP address of the NMS should be entered in the Create Trap Destination box.
Multiple destinations may be added.
