Getting Started 15
4 Getting Started
This section provides a short description of the minimum steps that must be taken in order to
start operating the TVG480.
If you are an experienced user of T-VIPS equipment or similar types of encoding/decoding
equipment the following description should enable you to quickly install the TVG480 JPEG2000
Post Production Gateway and start operation. If this is your first time to install such equipment
you are strongly adviced to read the full installation procedure. To gain full benefit of the
product functionality and capabilities refer to the user interface description.
The procedures outlined below are based on the assumption that the unit is in the factory
default state.
4.1 Configure the management Ethernet interface
Since the primary interface for controlling the TVG480 is Web based, the first step is to set up
the IP address for the management interface.
Changing the default IP address using the Web interface requires that your management computer may be configured with a static IP address. If a static IP address cannot be configured on
your computer the IP address may be configured via the terminal interface. The procedure is
described in the user manual.
Note: Avoid connecting through a network at this stage, as this may give
unpredictable results due to possible IP address conflict.
1. Connect an Ethernet cable directly between the PC and the Ethernet 1 port of the
TVG480. The default IP address of the TVG480 is 10.0.0.10/255.255.255.0. Configure the
PC to be on the same subnet as the TVG480.
2. Open your Web browser and type http://10.0.0.10 in the address field of the browser.
Log into the GUI with username admin and password salvador.
3. Browse to Device Info > Network > Ethernet 1 in the GUI, and set the IP address
settings required for your network. Click Apply to activate the new parameters.
4. The connection with your management PC will now be lost. To re-connect to the
TVG480 connect both the Ethernet 1 port of the unit and the management PC to the
network. The IP settings of the management PC must now be set to agree with the
network used.
5. Again, open your Web browser and type http: (New-IP-Address) in the address field of
the browser. Log into the GUI with username admin and password salvador.
An alternative to using the WEB browser to configure the IP address is to set up the address
using a local USB cable. This procedure is explained in Section 6.3.2.

16 Getting Started
4.2 Configure device name and time settings
1. Assign a name for the device in order to more easily identify the unit in the network.
Browse to Device Info > Product Info and enter a Name and Inventory ID. Click Apply
to activate.
2. Set date and time of the real time clock to ensure correct time stamping of the alarm
log entries. Browse to Device Info > Time Settings. The internal clock may be used to
time stamp alarm log entries, in which case a manual Date and Time adjust is all that
is needed. Click Apply to activate.
You may enable an external time source to provide a common reference for alarm logs
of all units of a system. Refer to the user manual for details.
4.3 Select the operational mode
Before starting to use the TVG480, it is essential to understand the fundamental operational
modes of the unit.
Note: Changing the operational mode requires reboot of the unit.
For the TVG480, there are three fundamental operational modes that need to be configured.
These are listed in the following table.
The operational modes are configured on the Device Info > Maintenance subpage as shown in
Figure 4.1.
To change an operational mode, select the new mode from the drop down lists/radio buttons.
When pressing the Apply button, you are asked to confirm reboot of the device. By accepting
the request, the unit will reboot and the device will start up in the new configured mode.
4.4 Connect the signals
After configuring the IP address and operational mode, the product is ready to do encoding or
decoding of video signals. To configure parameters needed for encoding, see Section 7.6. To
configure parameters needed for decoding, see Section 7.7.

Operational mode Description Values
Encode/Decode This mode selects whether the device shall operate as
a pure encoder, a pure decoder or a combined
encoder/decoder (“bidirectional mode”).
Ethernet Interface The TVG480 in standard configuration has three
network ports, but only two of them can be used
simultaneously. Depending on the operational mode,
it can operate with either two electrical Gigabit
Ethernet ports, or one SFP and one electrical Gigabit
Ethernet.
As a HW-option, the TVG480 can be delivered with
two additional network ports, one electrical and one
SFP. Except for Ethernet port 1 (electrical Gigabit),
which is always available, only ports of the same type,
electrical or SFP, can be used simultaneously.
Depending on the operational mode, it can thus
operate with either three electrical Gigabit Ethernet
ports, or one electrical Gigabit Ethernet port and two
SFP ports.
Video Field Rate Selects the fundamental video field rate of the unit.
It must be set to match the video formats that will
be used during operation.

5.5.2.2 Protective Earth/technical Earth
To achieve protection against earth faults in the installation introduced by connecting signal
cables etc., the equipment should always be connected to protective earth. If the mains supply
cable is disconnected while signal cables are connected to the equipment, an earth connection
should be ensured using the Technical Earth connection terminal on the rear panel of the unit.
Warning: This unit must be correctly earthed through the moulded plug
supplied. If the local mains supply does not provide an earth connection
do not connect the unit.
Caution: Consult the supply requirements in Appendix B prior to connecting the unit to the supply.
The unit has a Technical Earth terminal located in the rear panel. Its use is recommended. This
is not a protective earth for electrical shock protection; the terminal is provided in order to:
1. Ensure that all equipment chassis fixed in the rack are at the same technical earth
potential. To achieve this, connect a wire between the Technical Earth terminal and a
suitable point in the rack. To be effective all interconnected units should be earthed
this way.
2. Eliminate the migration of stray charges when interconnecting equipment.
Warning: If the terminal screw has to be replaced, use an M4x12mm long
pozidrive pan head. Using a longer screw may imply a safety hazard.
5.5.2.3 Connecting to the AC power supply
Warning: Do not overload wall outlets and extension cords as this can
result in fire hazard or electrical shock. The unit is not equipped with an
on/off switch. Ensure that the outlet socket is installed near the equipment
so that it is easily accessible. Failure to isolate the equipment properly may
cause a safety hazard.

5.6.2 SDI ports
The TVG480 has 2 HD-SDI input ports and 4 HD-SDI output ports. The ports are physically
capable of both HD-SDI and 3G-SDI.
Note: Input ports 3 and 4 are not used for the TVG480.
5.6.3 Ethernet Ports
The TVG480 in standard configuration provides three Ethernet ports, of which two can be used
simultaneously. Ethernet 1 is always active, together with either Ethernet 2 or SFP (Small FormFactor Pluggable). (Switching between the modes is done by changing the operational mode
parameter described in Section 4.3).
The default interface speed mode for the electrical Ethernet ports is 1000Base-T. In this mode
the port can auto sense between 10, 100 and 1000 Mbit/s. The operator is able to force the
TVG480 User’s Manual Rev. 2.8.24 (4422) ID: um_jpeg2000postproductiongateway

interface speed to various fixed speeds. This is normally not necessary, but may be useful for
minimizing the synchronisation time when reconnecting signal cables.
For flexibility, the TVG480 provides a Small Form-Factor Pluggable (SFP) slot to carry a copper or
optical SFP, allowing customers to use different SFPs for special distance, cost, existing infrastructure, and future expansion requirements. The TVG480 is prepared for electrical (1000Base-T) or
optical 1000BASE-SX and 1000BASE-LX SFP transceivers.
The LEDs for the electrical Ethernet ports are used as follows:

When there is a critical (level 6) alarm in the unit, if the unit has no power or any other
programmed condition for relay 1 is satisfied, there will be a connection between pin 6 and pin
7. Otherwise, there will be a connection between pin 7 and pin 8.
The optional (additional) relay will follow the same behaviour, except that it can also be programmed not to be activated for a critical (level 6) alarm.
A connection between pins 9 and 5 (or a TTL low on pin 9) will hold the unit reset, provided
this function has been enabled. The connection must be held for more than 0.5 seconds in order
to activate the reset. This can be used to force a hard reset of the unit from an external control
system. This pin can also be used as a general purpose input (GPI).

6 Operating the Equipment
The TVG480 is configured and controlled locally and remotely through a Flash-based Web
interface. The only application required on the computer to use this interface is a Web browser
and the Adobe Flash Player.
Note: Adobe Flash Player 9.0 or newer is required to use the Web interface
of the TVG480. As a general rule it is recommended to always use the
latest official release of Flash Player (version 10 or newer). If the Flash
Player is not installed on the adminstrator PC, a copy is provided on the CD delivered
with the device. Alternatively, the latest Adobe Flash Player can be downloaded
free of charge from
Note: When using Microsoft Internet Explorer, version 6.0 or higher is
required. It is however recommended to upgrade to version 8.0 or newer
for best performance.
http://www.adobe.com.
6.1 Accessing the graphical user interface
The default IP address of the TVG480 will most probably not be suitable for the network where
the unit will operate. Initially therefore, the user should change the IP address of the management interface so that access may be gained from the network.
The TVG480 offers two options to alter the user interface IP address; through an Ethernet
connection or using a USB terminal interface. If your management computer allows setting a
fixed IP address, change the IP address using the Ethernet option described in Section 6.3.1.
If a static address cannot be configured on your management computer, Section 6.3.2 gives the
procedure to initially configure device network parameters (IP, netmask, etc...) using the USB
terminal interface.
Configuring the device functionality according to operational needs is done using the Web
interface, see Chapter 7.
6.2 Password protection
Remote access to the device is controlled by password protection. If you access the TVG480
using the USB terminal interface a password is not required.
There are 3 user levels providing different user privileges, each with a separate default password:
Username Default password Privileges
admin salvador Full access to device
operator natal Configure setting, cannot alter passwords
guest guest View configuration and alarm logs

28 Operating the Equipment
The passwords can later be changed, either from the Web GUI or via the terminal.
6.2.1 Resetting the password list
If a password is lost, the password list can be reset to factory defaults via the local USB terminal
interface. To reset the password list, type the following command in the terminal interface:
userdb factory_defaults
Note: The factory_defaults option on the userdb command is avail-
able without administrator previledges only when accessing the terminal
via the local USB interface. In remote terminal sessions with a Telnet
client, administrator privileges are required to run the same command.
6.3 Changing the IP address of the unit
The default IP configuration on the Ethernet ports is described in Table 6.1.

1. Connect an Ethernet cable directly between the PC and the Ethernet port of choice on
the TVG480. Configure the PC to be on the same subnet as the TVG480. See Figure
6.2.
2. Open your Web browser and type the default ip address of the chosen interface in the
address field of the browser (for instance http://10.0.0.10 for Ethernet 1). Log into the
GUI with username admin and password salvador.
3. Browse to Device Info -> Network -> Ethernet 1 (resp. Ethernet 2) in the GUI, and set
the correct IP address settings. Click Apply to activate the new parameters. Figure 6.1
shows this GUI screen.
Note: Contact with the unit’s GUI will now be lost. Please type

Windows XP example
The screen-shot in Figure 6.2 shows how to configure the network interface in Windows
XP to communicate with the TVG480 via Ethernet 1 with factory default settings. The
IP address/netmask is set to 10.0.0.11/255.255.255.0 which is on the same subnet as the
TVG480, and does not conflict with the IP address of the device.

6.3.2 Changing the management port IP address via the terminal interface
If a static IP address cannot be configured on your computer, follow the procedure below to
configure the IP address via the terminal interface.
1. Install the USB driver from the product CD (setup_ftdi_usb_drivers.exe). (This step may
be omitted if the driver has already been installed.)
2. Connect your computer to the TVG480 via a USB cable to the USB port.
3. Access the terminal interface using a suitable terminal program, emulating an ANSI
terminal, on your PC (e.g. HyperTerminal). The USB will appear as a virtual COM
port on your PC. No specific serial port settings are required. Assure scroll lock is not
on. Type <enter> and see that you have a prompt (app>).
4. In the terminal, type the following command and press <Enter>:
net ipconfig --ip <ip address> --mask <subnet mask> --gw <default gateway> --if <interface
number>
Example:
app>net ipconfig --ip 10.40.80.100 --mask 255.255.255.0 --gw 10.40.80.1 --if 0
This will result in the IP address 10.40.80.100 being set on interface 0 (Ethernet 1). The subnet
mask is set to 255.255.255.0 and the default gateway to 10.40.80.1.
Note: The product CD shipped with the TVG480 contains a USB driver
to use for serial communication with the device on the USB port. The
MS Windows driver installation script is configured to give a one-to-one
relationship between the physical USB port number on the PC and the COM port
number to use on the PC. Drivers retrieved from http://www.ftdichip.com will also
work, but these may not have the same COM port number mapping.
6.3.3 Configuring automatic IP address assignment
The TVG480 can be configured to obtain an IP address automatically from a DHCP server on the
network. See section 6.3.1 for how to connect, and section 7.5.5.1.1.1 for how to configure this
from the GUI. Alternatively, configure it in the terminal by connecting as in 6.3.2 and issuing
the following command:
ipconfig --dhcp 1 --hostname <your_device_name> --if <interface-number>
Example:
ipconfig --dhcp 1 --hostname bonemachine-100 --if 0
Replace <your_device_name> with the name to register in the DNS system for your device.
After this, it should be possible to contact the unit in a browser using the URL:
http://<your_device_name>
TVG480 User’s Manual Rev. 2.8.24 (4422) ID: um_jpeg2000postproductiongateway
Page 31
Operating the Equipment 31
To disable automatic IP assignment, use the command
ipconfig --dhcp 0 --if <interface-number>
Note: Hostname registration is only done via the DHCP server, so if
DHCP is not enabled the hostname is not registered. The default hostname
used is on the format TVG480-<serial-no>-<interface-no>
Note: If automatic IP address assignment is configured and the interface
is connected to a network that does not support DHCP, the interface will
not receive an address and will fall back to a link local address after about 1
minute, using the first available address in the range 169.254.1.0 - 169.254.254.255.
If you have a unit that has been configured with DHCP, but current network does
not support it, you should be able to connect to the device for reconfiguration on a
local network connection using the address 169.254.1.0. If more devices are using
link local addresses, try 169.254.1.1, 169.254.1.2, etc.
6.4 Stereoscopic 3D operation
The TVG480 is capable of transporting high definition stereoscopic 3D TV over IP networks.
Figure 6.3 Encoding a stereoscopic 3D signal.
6.4.1 Requirements
To set up the TVG480 to transport stereoscopic 3D requires an Allow Stereo 3D operationlicence. Furthermore, at least two channels and encoders, resp. decoders, must be licensed, as
transmission of stereoscopic 3D signals requires two channels for encoding, resp. decoding.
ID: um_jpeg2000postproductiongateway TVG480 User’s Manual Rev. 2.8.24 (4422)
Page 32
32 Operating the Equipment
6.4.2 Configuration
The TVG480 must operate as a pure encoder, resp. pure decoder, to enable stereoscopic 3D
operation. The channels 1 and 2 (i.e. SDI-input port 1 and SDI-input port 2, Encoder 1 and
Encoder 2, etc) are used for the processing of stereoscopic 3D signals. Channel 1 will operate
as a master and channel 2 as a slave for the processing of 3D signals.
To set up the TVG480 for encoding of 3D signals do the following:
1. On the encoding unit, connect the (synchronized) stereoscopic SDI-signal to the SDI
input ports 1 and 2.
2. On the main tab for Encoder 1, enable the desired video format and enable the Stereo-
scopic 3D checkbox. This will turn Encoder 1 into the master and Encoder 2 into the
slave for 3D operation. All necessary IP connection parameters will be controlled via
Encoder 1. To maintain full flexibility, audio channels and other ancillary data can be
configured for each channel individually.
3. Set the IP destination address and port for Encoder 1. Encoder 2 will automatically send
to the same IP address, and a suitable destination port will automatically be chosen for
Encoder 2.
4. Finally, set the maximal available bitrate for 3D operation, i.e. for Encoder 1 and Encoder
2 combined.
On the decoding unit, select the desired video mode and stereo 3D operation on Decoder
1. Set the IP source address and port, and the remaining connection parameters will be set
automatically, with Decoder 2 being controlled by Decoder 1.
6.5 Hitless switching
The TVG480 enables hitless switching by combining smallcast on the transmitter side with
RTP/IP diversity reception on the receiver sider. Hitless switching provides redundancy by
protecting the stream against errors in IP transmission, but in a different manner compared to
Forward Error Correction (FEC). FEC is designed to protect the stream against single or short
burst packet losses, whereas hitless switching provides protection against loss of complete data
input, for example, due to link or equipment failure.
The main idea of hitless switching is to transmit two identical copies of the data stream over
separate network paths. At the receiver side, the data from the two incoming streams are
combined at packet level to form one data stream. This way, if one of the network paths
experiences severe packet loss or complete link failure, data from the other network path can
be used to output an error free stream.
At the transmitter side, the TVG480 allows sending identical copies of the data stream to a user
defined list of destinations by enabling smallcast. During smallcast transmission all identical
TVG480 User’s Manual Rev. 2.8.24 (4422) ID: um_jpeg2000postproductiongateway
Page 33
Operating the Equipment 33
streams are tagged with the same, randomly generated Synchronization Source ID (SSRC). For
each destination, the network interface (or a VLAN on any the interfaces) and separate unicast
or multicast destinations are selected so that the two data streams used for diversity reception
are routed to their respective network paths directly at the TVG480 or at the first sebsequent
network node.
At the receiver side, the IP source parameters are first configured as the master and slave sources
(i.e. first and second IP source). When the data streams have identical SSRCs, they are assumed
to be identical streams and used for diversity reception. Diversity reception operates on the RTP
packet level. The two incoming data streams are combined to form one error free stream as long
as there is one correctly received packet from either input stream. There will be packet loss at
the combined stream only when the packet is received on neither of the two IP sources. The
data stream resulting from combining the two incoming data streams will then be processed as
one RTP packet stream. RTP/IP diversity reception is a licensed feature and is required at the
receiver side. No licence is required for smallcast transmission.
Note: If the same data streams are received at both sources, the sources
will act as equal providers of data. If received streams at the sources are
not identical, the data from the master IP source will be used and data
from the slave IP source will be discarded.

In the status header the product name is shown on the left hand side, along with the T-VIPS
logo. Beside the logo is also shown the current operational mode of the unit.
The status bar displays an indicator showing the overall alarm status of the device. The colour
of the indicator shows the highest level alarm currently active in the unit. It is green if no alarm
is active. Other possible colours are described in Appendix E.
Several items are presented in the right corner/section of the header. Starting from the left:
• The user defined device name, if entered.
• A button to log out from the GUI.
• A button to switch current user level.
• A text showing the current user name.
• The local device time.
• A button for minimising the header. Using this hides a lot of the header information
and gives more space for the rest of the page.
• An activity indicator.
Note: The activity indicator shows one box for each request being
processed by the unit. Each box may change from green to red if ex-
cessive time elapses during the processing. During normal operation, no
squares should turn red. If squares start turning red there might be a problem with
the communication between the device and the computer, or the device may be
busy. If the device has not responded to a request within 20 seconds, the indicator
turns yellow. If no response has been received after 40 seconds, it turns red.
A tab bar is located beneath the status header. The exact number of tabs and tab labelling
depends on the units operational mode and licences. Clicking a tab will open the corresponding
page with a navigation pane to the left as shown in Figure 7.4. This pane is used to navigate
between sub-pages of the tab.

This page displays the current status of the device. It consists of a block diagram illustrating the
device with its input and output ports, an overview of the currently active network interfaces
and a list of currently active alarms.
Block Diagram
The block diagram provides a compact view of the unit status. It shows:
• The name of the functional units of the device.
• The name and alarm status of each input/output port.
• The status of non-I/O port related alarms.
The alarm status is shown with colours indicating the severity of the alarm. The various
severities and colours used are described in
Access to additional information pertaining to the various ports of the block diagram is
provided by hovering the mouse pointer over the port within the diagram. The port
representations in the diagram also act as shortcuts to the corresponding configuration
page for the port. The shortcut is activated by clicking on the port in the diagram.
Right-clicking the status block diagram top bar offers a shortcut to clear device statistics
parameters. Selecting Reset device statistics brings up a dialogue where you can select which
information to clear.

Current Alarms
The bottom part of the page shows the currently active alarms. Some alarms may contain
several sub-entries that are displayed by clicking on the arrow in front of the entry’s
description. The severity of each alarm is represented by an error indicator (visually
similar to a LED). The colour of the indicator represents the severity level configured for
the specified alarm. The various severities and colours used are described in Appendix
E.
The Current Alarms table contains six columns:
Description
Description of the alarm condition.
For sub-entries, the extended index is shown in brackets. To the left is an indicator visualising the severity of the alarm. The indicator has a tool-tip providing a textual description
of the alarm severity.
On Time
The time when the alarm was raised.
Alarm type
Category of the alarm, i.e. Port, System, Switch etc.
Source
This identifies the source of the alarm. For port alarms, this is a reference to the specific
port raising the alarm. This field has a tool-tip showing the subid1 and subid2 values for
the alarm.

Subid1
Reserved for future use in multi-slot chassis and is always set to 1 in the TVG480.
Subid2
The device or port to which the alarm relates. The value is zero for alarms that are
related to the device rather than to a specific port. Values of 1 and up reference
specific ports.
Alarm ID
Each alarm condition has an associated numerical alarm ID.
Details
An optional string to provide more alarm information in human readable form. The format
of this string depends on the alarm type. Hovering the mouse over this field produces a

7.4.2 Alarm log
Figure 7.6 Alarm log
The alarm log shows every alarm that has been triggered since the last time the alarm log was
cleared.
The table consists of the same columns as the Current Alarms table, but does not show details
by default. You can change which columns to show, including the details column, in Section
7.5.2.4. Additionally a column named Off Time shows the time the alarm condition was cleared.
Rows will not have the Off Time set if the alarm is still active.
Each row provides additional information via a tool-tip shown when hovering the cursor over
the row. The tool-tip entries are:
Sequence #
A number identifying this specific alarm instance. This number is incremented each time
an alarm condition is raised.

SubID 1
The primary numerical index of the alarm instance. This index is reserved for future use
and is always set to 1 in the TVG480.
SubID 2
The secondary numerical index of the alarm instance. When the alarm is of type Port
alarm this index contains the port number for which the alarm was raised. Other types of
alarms may use this index to identify a sub module, but normally it is set to 0.
SubID 3
The tertiary numerical index of the alarm instance. The use of SubID 3 depends on the
type of alarm. Some of the Port type alarms use this index to signal the PID value or
Service ID for which the alarm was raised. For example, if the CC Error of a PID is raised
then the PID value is given by SubID 3.
Details
An optional string providing more information about the alarm in human readable form.
The content and format of this string depends on the alarm type.
Beneath the alarm table is a caption showing the total count of alarms currently stored in the
alarm log.
To the right of the table are three buttons and a check box.
Clear Alarm Log
Clears all alarms from the alarm log.
Export to File
Saves the alarm log to a comma-separated value (.CSV) file. The button opens a file
dialogue where the user can choose the destination to save the file on the computer.
Export to Browser
Opens the complete log in a new browser window, showing the alarm log as a commaseparated value list. The format of this list is a text file (not HTML or XML).
Enable updates
This check box can be unchecked to stop the log from scrolling if new alarms are triggered
while watching the log.
The alarm log is stored in non-volatile memory, so the content is kept even if the unit is rebooted.
The log is circular. Events occurring after the maximum number of entries has been reached
overwrite the oldest entries in the log. The maximum number of stored entries is 10000.
7.5 Device Info
The device info page contains all the information and settings that are not related to a single
input or output port. It is divided into multiple sub pages accessed via the navigation list to
the left. In the list of physical interfaces in the navigation list, the currently active interface is
shown in bold. See Figure 7.7.

Inventory ID
Configures the current user defined inventory ID of the unit. This parameter, together with
the management network parameters are used as device identifiers and remain untouched
if the unit configuration is modified. It is only intended as a label/tag and will not affect
the operation of the unit.
Configuration ID
Configure a user defined name for the current configuration of the unit. This name will, if
given, be diplayed in brackets after the unit name in the status header as shown in Figure
7.3. The Configuration ID does not, as opposed to the Name and Inventory ID fields, remain
untouched when loading a new unit configuration. Loading a new unit configuration will
change the Configuration ID. See Section 7.5.6 on how to load a new configuration.
Product name
Displays the name of the product as designated by T-VIPS.
Serial number
The serial number of the device.
Software version
The version of the software currently installed on the device. The software version is given
by the following syntax:
<major_version>.<minor_version>.<patch_version>
The convention for the SW version numbering is as follows:
major_version
Incremented for significant SW changes.
minor_version
Incremented for minor changes. The minor version number is even for official retail
releases and odd for beta releases.
patch_version
If minor_version is even, patch_version gives the patch level of that version. A patch
level of zero means the SW is built on the latest code base, an even patch_version
means this is a released SW patch on a previous release. An odd patch_version means
that this is a test version. If minor is odd, this is a beta version, and the patch_version
simply gives the build number.
Software build time
Reports the time of which the current release image was built.
Device up time
The amount of time that has passed since the device was last reset.
Internal temperature
This shows the current internal temperature of the unit in degrees Celsius and Fahrenheit.
Fan speed
This bar chart shows the current speed of the device fans relative to full speed.

7.5.2.1 Device alarms
The page shown in Figure 7.9 provides the administrator with an interface to view the status
and configure the behaviour of all alarms related to the system. At the top the Reset Alarm
Counters button allows resetting all alarm counters simultaneously.
The page is divided into two parts. On the left is a tree that shows all the alarms. The colour
of the folder icon and the specific indicator represents the current status of the alarm. The text
to the right of the tree shows the currently configured severity of the alarm.
The right hand side of the page displays the Alarm Details field when an alarm is selected:
Alarm ID
The internal numerical ID of the selected alarm.
Alarm
Title of the alarm.
Description
Brief description of the condition of the alarm.
Severity
A configurable option defining the severity of the alarm. Options in the pull-down box
range between Filtered (meaning ignored) to Critical. The text in brackets represents the
default setting.
Alarm turned on
The number of times the alarm has transitioned from off to on since last reset of the alarm
counter.
Error count
Not used.
’Reset Counters’ button
When clicked, clears the alarm counters for the current alarm.
The right-click context menu of the device alarm page provides an option to reset the counters
of all the alarms in the Device Info tree.
7.5.2.2 Global configuration
This page provides an interface to configure globally the behaviour of all alarms. By default
ports use the global configuration settings but each port alarm can be configured individually
to override these settings.
For each alarm a custom severity level can be configured. In addition the alarms can be omitted
from the alarm log and trap transmission.
Edited rows are highlighted until changes have been applied.
Tip: For the Log and Send Trap columns, you can quickly select/deselect
all items by right-clicking on the header fields in the columns.

The Virtual Relays field shown in Figure 7.11 also includes settings for the so-called virtual
relays. These are programmable status indicators that can be set to react to any specific alarm
condition. In the simplest case you may want to enable a relay in case a specific alarm ID turns
up. In another case you may want to enable a relay if a specific alarm turns up on a given port.
Each relay status are exported on SNMP. Activation of a virtual relay also generates a specific
alarm, named "Virtual alarm relay activated" (ID=169).
The key element in the settings of the virtual relays is the Expression value. The expression is
very close to SQL in syntax and specifies when the relay should be activated. The behaviour is
as follows for each virtual relay:
1. Each active alarm event is evaluated against the Expression for the virtual relay (if
enabled).
2. If the expression evaluates to true, the Count value is increased by 1. You can at any
time see the current count value. The Count value simply tells you how many of the
current (active) alarm events in the unit that matches the expression.
3. If the count value is larger than or equal (>=) to the Count Thresh. value the relay is
activated.
The expressions are validated before they are accepted by the unit.
Table 7.1 shows the field
values you may enter in an expression.
Table 7.1 Legal field values to use in expressions
Field name Extracts from event: Type Sample expression
id Alarm ID Number id = 169
text Alarm text Text text = ’Defective fan’
type_num Type number Number type_num = 13
type_text Type text Text type_text = ’port’
sev Severity (number 2-6) Number sev = 6
details Alarm details (text) Text details = ’PID 113’
subid1 Alarm subid1 value Number subid1 = 1
subid2 Alarm subid2 value Number subid2 = 2
subid3 Alarm subid3 value Number subid3 = 1190
port Synonym for subid2 Number port = 2
service Synonym for subid3 Number service = 102
pid Synonym for subid3 Number pid = 2000
In the expressions you may enter parentheses to group sub-expressions together. Together with
the supported list of operators this gives great flexibility in constructing advanced “match”
patterns.
Table 7.2 summarises the operator types you are allowed to use. Please note that the examples
below are used for illustration purposes only. For example, the plus and minus operators may
not be very useful in practise, but they are included in this table for completeness.

Table 7.2 Legal operators to use in expressions
Operator Description Sample
= Equal id = 169
!= Not equal id != 169
AND Logical AND id = 169 AND port = 2
OR Logical OR id = 169 OR id = 200
IN Set operator. Returns true if left-hand part is included in set to the right. id IN (169,200,201)
+ Addition id + 9 = 169
- Subtraction id - 8 = 160
* Multiply id * 10 = 100
/ Divide id / 20 = 8
> Greater than id > 100
< Less than id < 90
>= Greater than or equal id >= 100
<= Less than or equal id <= 100
Some examples are given in Table 7.3.
Table 7.3 Expression examples
Task Expression Count threshold value
To generate an alarm when any alarm with
ID = 200 turns up (independent on source)
To generate an alarm when alarm with ID =
200 turns up on port with ID = 1 (subid2 =
1)
To generate an alarm when alarm with ID =
200 turns up on both port 1 AND port 2
id = 200 1
(id = 200) AND (port = 1) 1
(id = 200) AND ((port = 1) OR (port
= 2))
2
Note the last example in the table: Here the count threshold value must be set to 2 to get the
expected behaviour. This is because the expression entered matches two different alarm events
(port=1 or port=2), and in order to match them both two matches are required in the global
alarm list.

Active
The time source currently in use by the time synchroniser.
The Manual Adjust Time field allows the operator to set the time. The manually configured
time will only be used when no other time sources are configured in the Prioritised time sources
list.
The Timesource prioritisation field contains two lists showing configured time sources. Disabled
time sources are greyed out. Enabled time sources are shown with an indication of the time
source status. The list to the right shows time sources that are defined but not used by the
time synchroniser. Enabled time sources may be moved to the leftmost list by using the arrowleft button, and back again by using the arrow-right button. Time sources in the left hand
list are used by the time synchroniser to set the time. They are listed in prioritised order; the
source with the highest priority at the top. The order of priority can be altered by clicking an
item in the list and using the up or down arrows to the left of the list to increase or decrease,
respectively, the item priority. The time synchroniser will use the time source with the highest
priority whose status is “OK” (represented by a green indicator).

For switched inputs, you may select the time source to get time from the input switch group, which will make the time source retrieve the time from the
currently active input in the switch.
To remove time sources, Select them in the list and click the “Remove Timesource” button. Time
sources for dynamic ports such as IP inputs and Switch inputs, are automatically removed if
the dynamic port is removed.
Located below the lists is also a field to define the maximum allowed time interval between
updates from the currently used time source. Exeeding this interval the source is considered
“Not OK” and the synchroniser selects the next source in the prioritised list.
Upon selecting a time source, the Timesource Details box at the bottom right of the page provides
additional details relating to the selected time source. Depending on the type of time source
selected the box may contain some or all of the following parameters:
Active
A checkbox to enable or disable the time source. Disabled time sources are never updated.
Time sources configured and present in the prioritised list must be removed before they
can be disabled.
IP address

Reference precision
The expected timing accuracy of the current time source.
7.5.4 Reference Sync
This page provides means to synchronise the video processing of the unit to an external analogue
video signal, typically a black-burst SD signal.
Or to a clock signal derived from an IP input stream. The analogue reference source signal is
connected to the rear panel sync input connector.
Figure 7.15 Reference Sync
The Reference Sync page provides a check box to enable or disable a synchronising source for
the video decoder. The Reference source dropdown menu allows the selection of the source
signal, either the analog reference signal or, if licensed, the input stream of one of the four
decoders.
A status field is provided indicating if the sync signal is present, and the associated video
format. Offset indicates the input clock offset in ppm compared with the internally generated
clock signal.
7.5.4.1 IP RX Video RefSync
The purpose of using an IP input stream as source for reference sync is to approximately
synchronize the video output clock on the decoder to the video clock of the input signal to
the encoder. On the encoder, the video input signal determines the exact rate at which packets
are transmitted. On the decoder, the video output clock, and hence the rate at which data
is consumed and decoded, is derived from the decoding unit’s internal clock. If there is a
difference between the video input clock and the video output clock (in the ppm range), the
decoder will periodically either accumulate or run out of data, leading to frame skips or frame
repeats.
Using the IP RX Video RefSync feature, the internal clock on the decoding unit is adjusted to
the “clock” of the incoming data stream. By sampling the arrival time of incoming packets, the
video clock of the video input signal is reconstructed at the encoder and the internal clock is
synchronized to this reconstructed clock signal. This way, the internal clock of the decoding
unit will run at the same clock frequency as the video input signal. Thus the decoder will not
accumulate or run out of data and frame skips and frame repeats will be avoided.
The Sync loss action allows chosing how to respond to sync loss on the source signal. The Sync
loss action is only available when using an IP input stream as the refsync source. Full resync“

WEB Interface 73
The IP Routing table lets the user configure IP routing rules for the unit. These rules tell the
unit which interface to send IP traffic to, based on the destination IP address of the traffic.
Destination
The destination IP address to use for matching against this routing rule.
Netmask
The subnet mask to use for matching against this routing rule.
Gateway
The IP destination to send a packet to if the destination address of the packet is on a
different subnet than the destination interface.
Interface
IP packets matching this rule will be sent through this interface.
Metric
The metric of the routing rule. If more than one rule matches a destination address the
rule with the lowest metric will be used.
When an IP packet is sent from the unit the destination address of the packet is matched against
the configured routing rules. If the destination address matches one or more rules the rule with
the lowest metric will be used. The packet will then be forwarded to the interface determined
by this rule. If the destination address is on a different subnet than the configured interface the
packet will be sent to the gateway determined by the rule.
Below the table is a checkbox where the user can Allow IP forwarding. If enabled incoming TCP
packets that are not addressed to the unit will be forwarded to an interface according to the
routing rules. The receiving interface must have management traffic enabled to forward TCP
traffic to a different interface.
Note: Modifying the IP routing rules may cause loss of contact with the
unit. Make sure you will still be able to contact the unit with the new
settings before applying the changes.

7.5.5.6.1 Ping
The ping tool can be used to check for connectivity between devices. It is especially useful to
ping the receiving data port from the IP transmitter to see if the receiver can be reached.
Figure 7.30 The Ping tool
IP destination
The IP address of the receiving data port. The ping messages will be routed to the matching
Ethernet port, either data or management, or to the port configured as default management
interface if the specified IP address does not match either of the two sub-nets. Note that
if you are pinging between data interfaces, the Allow ping response option on the network
page Advanced tab (see Section 7.5.5.1.3) must be enabled both in the transmitter and the
receiver.
Note: When the IP destination is a multicast address one cannot expect to
receive a response to a ping request. It is recommended to test connectivity
using the device’s actual IP address.
TTL (Time To Live)
Enter the time to live value for the ping messages here. The time to live value is a field in
the IP protocol header that is decremented once for each router that the datagram passes.
When the count reaches 0, the datagram is discarded. You can use this to check the
number of routers between the transmitter and the receiver by starting with a low value
and increment it until ping responses are received. TTL is also specified for each data
channel on the IP transmitter, and must be high enough to reach the receiver. Values range
from 1 to 255.
Ping count
The number of ping messages to send. The messages are transmitted with an interval of
about 1 second.
MTU
Maximum Transfer Unit. Specify a length for the ICMP frames to check that frames with
given length pass through the network. The ICMP data payload size is adjusted to yield
Ethernet frames with the specified length. The ping messages are transmitted with the
“don’t fragment” bit set.

sequence is displayed in the status frame. Status values are reset on pressing the start
button. After pressing the start button the label switches to Stop, and the button can be
pressed again to cancel the pinging sequence.
OK responses
The number of ping responses received.
Timeouts
The number of ping requests that were not answered. If the timeout counter is incrementing
while the OK responses counter is zero, there is no contact with the specified IP address.
Last roundtrip
The round trip time measured for the last ping request in units of milliseconds.
Average roundtrip
The average round trip time measured for the ping requests in this session. The value is
reset every time the start button is pressed.
Min roundtrip
The shortest round trip time registered for the ping requests in this session.
Max roundtrip
The longest round trip time measured for the ping requests in this session.
Remaining
The number of remaining ping requests in this session.
7.5.5.6.2 Traceroute
The traceroute tool can be used to debug the network connectivity with a given host by tracking
the router hops between the TVG480 and the host. Traceroute uses ICMP ping messages with
increasing TTL to track the router hops.
Settings
IP Destination
The IP address of the host to check. IP routing decides which interface the ICMP
messages are sent on.
Number of hops
This parameter sets a roof to the number of hops that are tracked. Normally this
parameter can be set fairly low.
MTU
Maximum Transfer Unit. This parameter can be used to transmit messages with a
given length. ICMP messages are transmitted with the don’t fragment bit set to yield
errors when MTU of a link is too small for the frame.

• Transfers the configuration snapshot from the administrator’s PC to the device
• Validates the configuration to make sure that all the options in the file are compatible
with each other and with the device itself.
• Presents the user with additional information, such as skipped options
• Activates the configuration
When an import has been successfully completed the progress bar colour turns green and
changes its text to OK. Upon failure at any point the progress bar will turn red, and details of
the reason for the failure will be presented as messages in the Result of last config activation
list.
By default, options specific to the device, including device name and management port network
configuration, are disregarded during the import process. This is a convenience feature allowing
configurations to be easily moved from one device to another. It also makes management easier
in that the Web UI will continue to communicate with the device after a new configuration has
been loaded. The default behaviour can be changed with the load options, please see Section
7.5.6.1.4 for a desciption of the options.
Partial configuration files are supported to allow a subset of configuration options to be changed
instead of the entire unit configuration. Partial configuration files are validated as differences
from the current running configuration upon import before being made active.
7.5.6.1.3 Load Configuration from Remote Device
The Load Configuration from Remote Device makes it easy to copy the configuration of another
device to this device. This device will therefore be a clone of the remote device, except for
device specific parameters such as IP addresses and product name. Loading a configuration
from Remote Device is essentially equal to saving the configuration file of another device, and
uploading it to this device.
The configuration field includes the IP address of the remote device. Entering an IP address
and pressing the Contact Device button will check if the connection is valid and display some
information about the device if successful. If the connection is valid, the Load Config button
will become clickable.

Note: It is possible, but not advisable, to load configuration from other
model types. Even if loading from the same model type, loading a configuration might also fail, especially if the two devices have different feature
sets. See Section 7.5.7.1 for a list of features.
Please see next chapter (Section 7.5.6.1.4) for a description of the load options.
7.5.6.1.4 Load options
These options are used to modify the behaviour on configuration loading. The options are
available both when loading from a file (Section 7.5.6.1.2) and when loading from a remove
device (Section 7.5.6.1.3).
Default action
This parameter modifies the algorithm used when modifying lists (collections) in the configuration.
Restore
Modify list to contain exactly the entries specified in the file loaded.
Merge
List entries that are present in the running configuration but not in the file loaded
are left in the list. New entries specified in the file loaded but not in the current
configuation are added. Entries present both in file loaded and in running config are
modified.
Update
Only update nodes that are present in running configuration and in file loaded, i.e
no list entries are added or removed.
Overwrite
This parameter is used to modify how specially tagged parameters are handled during file
loading.

7.5.6.4 Emergency Switch
This feature allows the TVG480 to communicate with a central emergency switch unit. The
emergency switch unit is designed to facilitate simultaneous configuration switching of all units
under its supervision. In this way the operational mode of a comprehensive system may be
changed at the press of a single button. Contact T-VIPS for further information on the emergency
switch unit.
Communication with the emergency switch is IP based using the UDP protocol. Each unit
enabled for emergency switch control polls the emergency switch repetitively to determine the
switch position. The Emergency Switch tab provides the means to configure the behaviour of
the TVG480 under emergency switch control.

Once an image file is specified by using the Browse button, the Upload button is used to
transmit the file from the administrator PC to the device. Once the file has been transferred,
it is verified using and internal checksum value and set as the new active firmware image.
If the upload is successful the progress bar turns green and the unit reboots itself loading
the new image, unless the Reboot on success option has been unchecked.
If the upload is unsuccessful the progress bar turns red and an error message is displayed
in the Status field.
Cancel
The Cancel button is enabled during the upload process and can be clicked to cancel the
operation. It is not possible to continue a cancelled upload.
Reboot on success
This checkbox is checked by default but can be unchecked to disable automatic reboot
upon SW loading completion. If this option is not checked the SW will load but will not
be activated before the user performs a manual reboot. Note that this option is not stored
on the device, and Reboot on success will be enabled next time you enter the SW upgrade
page.
During SW loading, an alarm SW loading in progress is set with the Details field displaying the
IP address of the machine from which the loading was initiated. The alarm is turned off when
the loading is completed or terminated.
If the Reboot on success option is active the unit will automatically reboot when loading is
complete, otherwise an alarm New SW pending is set to indicate that a new SW will be used
on next manual reboot.
After uploading, if the Progress bar shows OK but the web interface does not change to the

WEB Interface 93
Figure 7.43 shows the main configuration page. The parameters in the Encoder Configuration
field are:
Label
A label can be attached in order to more easily identify the encoder in a large (multiencoder) system. This name will be reflected in the block diagram of the main status page
(Figure 7.5).
Encoder mode
Enables/disables the encoder. Choices are: Disabled or HD (1.5G).
Max total bitrate
Configures the maximum total bitrate for the encoding process (including audio, VBI and
other data types in addition to video). This bitrate is the Ethernet bitrate, which includes
all transport layers down to Ethernet framing, i.e. from the fields MAC destination to
Frame check sequence (CRC), inclusive.
Constant bitrate
Enables transmission with a constant bitrate, where the bitrate is the configured max total
bitrate. Stuffing packets will be generated to achieve the desired bitrate.
Stereoscopic 3D
Enable this to turn 3D mode on. If enabled, the second encoder will be used as a slave to
this encoder. See
Section 6.4 for details on 3D operation.
Max total bitrate 3D
Only used in 3D mode. Configures the total bitrate to be used for an encoder pair in 3D
mode.
To the right of the encoder configuration field two status fields provide input source status and
encoder status, respectively.
The Input Source Status field shows the status of the available input sources, whether SDI sync
has been acquired, the video format of the SDI input and content of the currently configured
generated signal.
The Encoder Status shows what source is used for encoding, the operational state of the encoder,
the video format of the encoded source, the maximum and current compressed video bitrates,
the current chroma weight and the encoded audio bitrate.
Note: If a signal different from the SDI input signal is used as source
for encoding, either because sync has been lost or because the generated
signal has been chosen, a warning is triggered informing the user of which
signal is used for encoding and why.
In the IP Output Basic Configuration field the IP destination address and UDP destination port
are configured, and a check box is provided to enable or disable the IP stream. It is also possible
to override the automatic selection of destination interface. See Section 7.6.4 for more details.
ID: um_jpeg2000postproductiongateway TVG480 User’s Manual Rev. 2.8.24 (4422)
Page 94

Adjacent is the IP output Status field which indicates the output interface used, whether the
IP address has been resolved (the destination can be reached), and the corresponding MAC
address. This field also shows the total Ethernet output bitrate.
Immediately below these fields, next to the Apply, Refresh and Reset Statistics buttons, there are
two additional buttons, “Add IP Destination” and “Copy IP Destination”. These can be used to
make the Encoder transmit the same contents to several IP destinations, so called IP smallcast,
where an additional IP destination can be configured based on the current one (Copy) or as a
completely new one (Add).
When multiple IP outputs have been configured for the same Encoder, the IP Basic Configuration
and IP Output Status fields are replaced by the IP Destinations list, see Figure 7.44. This list
gives an overview of all configured IP destinations, and each one of these is available for detailed
configuration through the navigation pane on the left hand side.

selected, the chroma bitrate weight is automatically calculated based on the total video bitrate.
The chroma weight is then 5% for video bitrates less than 50 Mbit/s, 50% for video bitrates
above 300 Mbit/s and progressively scaled in between.
Integer or floating point processing may be selected in the pull-down list. Two wavelet filters are
supported; the 9/7 floating-point filter and the 5/3 integer filter. The floating-point filter is more
efficient in terms of compression efficiency, while the integer filter is more robust in systems
with multiple JPEG2000 encoding/decoding stages, as rounding errors are not accumulated.

channel is present, where green signifies presence of sound and grey signifies silence. A small
grey circle signifies that the audio channel is not present.
Up to 8 audio channel pairs may be present, and the left and right channels of each pair may
be enabled individually. Two status fields are provided to display the audio input and output
status, respectively.

7.6.2.5 HD VBI
This page allows the user to configure the insertion of raw VBI data (luma data) into HD signals,
by listing the lines one wants to extract and transmit. A single line of raw VBI data consumes
about 4-500 Kbit/s of the available bitrate.
Note: When raw VBI (luma data) extraction is enabled on a given line,
neither the luma nor the chroma component of that line will not be scanned
for ancillary data.
Figure 7.48 Encoder HD VBI page
7.6.2.6 ANC
This page allows to configure and monitor the transmission of ancillary data. By default, all
ancillary data are transmitted transparently. The horizontal blanking area of every line and all
VBI lines, except for those configured for raw VBI transmission, are scanned for ancillary data.
An alarm is raised if the configured ancillary data bitrate is insufficient for the ancillary data
present in the signal. Also, if the bitrate is insufficient, some ancillary data packets will be
dropped.
Note: Since HD audio control packets are mandatory for HD-SDI, they
will not count against the configured ancillary data bitrate and will be
transmitted even if no ANC bitrate has been reserved.
Ancillary data bitrate
Configure how much bitrate should be reserved for ancillary data. Note that the alarm
ID: um_jpeg2000postproductiongateway TVG480 User’s Manual Rev. 2.8.24 (4422)
Page 98

for insufficient bitrate may be raised, even though the average bitrate used is below the
configured bitrate. This is because the configured ancillary data bitrate must take peak
occurrences of ancillary data into account.
Current ancillary bitrate
This displays the average bitrate used for ancillary data.
Present DIDs
This list monitors the DIDs and SDIDs present in the signal. The list is refreshed continuously. DIDs present only very sporadically may disappear and reappear on the list.
Figure 7.49 Encoder Ancillary Data page
7.6.2.7 Advanced
This page allows the user to configure the sync loss handling and the generated signal. The
sync loss signal and the generated signal can be configured individually.
Encoder action on sync loss
Configure how the encoder should react on losing sync: Stop encoding, encode the last
complete SDI frame or encode a custom image.
Delay before switching
This configures the delay before switching to the configured sync loss action. The default
action on losing sync is to encode a freeze frame, i.e. the last good frame. If the encoder
is configured to encode a freeze frame the encoder will stay in this state until SDI sync is
re-acquired.
Custom image
For both the sync loss signal and the generated signal, one can configure the content of
the custom image. The available custom images are:
• black
• green
TVG480 User’s Manual Rev. 2.8.24 (4422) ID: um_jpeg2000postproductiongateway
Page 99
WEB Interface 99
• grey
• magenta
For sync loss handling, the video format of the custom image follows the video format of the
SDI input signal.
Enable custom text overlay
For both the sync loss custom image and the generated signal one may overlay a single
line of white text on the custom image. The font size and position of the text is fixed, the
content can be configured by the user.
Encoder source
On the generated signal page, one may manually override the SDI input signal and force
the generated signal to be used as signal source for the encoder.
Custom format
For the generated signal, one may in addition to the image content select a video format.
The list of available video formats depend on the current configuration of the encoders
and decoders. If the selected video format is not available in the current configuration, the
best available substitute video format is used for the generated signal.
