The OTT software option is available on the VB330-SW and enables monitoring of up to 500
adaptive bitrate channels in steps of 5 or 50 (Bulk OTT option) OTT engines depending on licensing.
A built-in web server in the VB330-SW allows remote signal monitoring using a standard web
browser. This can be managed either through a separate Ethernet network, or by using the regular
video/data network – both IPv4 and IPv6 are supported.
The VB330-SW 10G Software Probe can also be managed via the VideoBRIDGE Controller.
The VideoBRIDGE Controller will add management features like alarm aggregation and report
functionality.
The 10G Software Probe is a server appliance, that can be installed onto any server that meets
the minimum requirements specified in chapter 3.
1.1.2 10G Software Probe – Functionality
An IP-based network is fully transparent with respect to signal contents quality, provided that the IP
packets arrive, and provided that they arrive in time. The 10G Software Probe therefore uses the
8VB330-SW 10G Software Probe User’s Manual version 5.5

patented MediaWindow to allow monitoring at-a-glance of packet loss and errors in inter-packet
arrival time. This way the operator can conveniently ensure correct signal quality at IP-level.
The advanced Ethernet protocol analysis tool automatically detects all protocols carried over Ethernet
past the port the 10G Software Probe is connected to, and it displays statistics like percentage
utilization of the interface and percentage of the different transported protocols. This gives the 10G
Software Probe a real-time sniffer capability.
The 10G Software Probe allows the user to define a Return Data Path (RDP), using the regular
video/data network or the management network to return a stream. A faulty signal can then be
further analyzed at the studio premises, when necessary.
The recording functionality allows the user to record a stream, either triggered manually by the user
or triggered by a user defined alarm.
Full Service Monitoring (FSM) checks that vital system components like CA-servers are active.
Optional Ethernet TR 290 monitoring allows the operator to check parameters like transport stream
sync and PSI/SI standards conformity. This option also performs further PSI/SI analysis, making it
possible to view PSI/SI contents. PID and service bitrates are also continuously measured.
Optional OTT monitoring allows the operator to set up active testing of Over-the-top type signals
as found in adaptive bitrate streaming architectures. Formats supported include Apple ™ HLS,
Microsoft ™ Smoothstream, RTMP, MPEG DASH, Adobe ™ HDS and Nullsoft SHOUTcast™.
The 10G Software Probe can be expanded through license options to monitor the T2MI protocol
layer as found in DVB-T2 networks.
VB330-SW 10G Software Probe User’s Manual version 5.5 9

The 10G Software Probe can also be licensed with an SCTE 35 option that allows monitoring and
logging of splice time codes embedded in the transport streams.
1.2 How to Use This Manual
This User’s Manual is valid for software version 5.5 of the VB330-SW 10G Software Probe.
Throughout this manual the term stream is often used rather than unicast or multicast. One stream
may consist of one or more services, and refers to one IP uni- or multicast.
Chapter 2 PRINCIPLE OF OPERATION provides a simplified block-diagram overview of the
probe.
Chapter 3 INSTALLATION AND INITIAL SETUP explains how to install the software on a server.
Chapter 4 QUICK SETUP GUIDE contains a quick setup guide; a step-by-step description of how
to setup the 10G Software Probe once the initial setup has been performed.
Chapter 5 THE SOFTWARE PROBE GRAPHICAL USER INTERFACE describes the graphical
user interface (GUI) as seen when pointing a web browser to the 10G Software Probe’s IP address.

A simplified diagram of the alarm handling mechanisms of the 10G Software Probe is shown in
figure 2.2. The input signals are continuously analyzed, and measured data are checked against
user defined threshold values. If the data do not comply with the threshold values alarms will be
generated. The overall alarm settings further make it possible to enable and disable alarms, thus
defining which alarms should be reported in the 10G Software Probe alarm list and sent as SNMP
traps to an external management system.

• Red Hat Enterprise Linux Server release 7 (7.3–7.6) for x86_64
If the system is upgraded to an unsupported operating system release, an error message will be
displayed in the Application notification menu upon accessing the user interface. Check the release
notes available for the currently installed software version before updating to a new operating system
release.
3.2 First-time Installation
Make sure that the server hardware matches the requirements listed above and then follow the
procedure outlined below.
1. Obtain the latest installation kickstart image from Sencore.
Installation media is provided both for CentOS Linux and Red Hat Enterprise Linux. If you
install the Red Hat Enterprise Linux version, you will need an active subscription for Red Hat
Enterprise Linux server.
2. Insert the installation medium into the server:
• For DVD-based installations, burn the downloaded ISO image to a DVD and insert into
the server.
• For USB-based installation, transfer the downloaded image to a USB mass storage device
using a tool such as dd (Mac, Unix, Linux) or USBWriter1(Windows).
• For installation in a virtualized environment, attach the downloaded ISO image to a
virtual DVD-ROM unit.
Note: Please read the advice on how to configure the virtual machine in section 3.3 to
ensure optimal performance.
3. Boot the server and make sure that the primary boot device is set appropriately. If the system
fails to boot from the medium, you may need to configure the boot loader for ‘legacy BIOS
mode’.
4. The installer will run, please follow the on-screen prompts to install the system, taking note of
the following:
•IMPORTANT: Leave ‘Software selection’ at ‘Custom software selected’.
•IMPORTANT: In the ‘Installation Destination’, the default partitioning will create a
large /home partition, which is unused. To avoid this, use the ‘I will configure partitioning’
option. Then use the ‘Click here to create them automatically’ and manually reduce the
size of (or remove) the /home partition, instead giving that space to the /partition.
1https://sourceforge.net/projects/usbwriter/
14 VB330-SW 10G Software Probe User’s Manual version 5.5

• We recommend that you configure network settings (IP address, gateway, DNS) within
the installer. Post-installation network configuration can be performed using the nmtui
utility, please refer to D Appendix: Network configuration for details.
• The default installation does not provide any graphical user interface environment. This
can be installed later if desired, please refer to the CentOS Linux
2
or Red Hat Enterprise
Linux3documentation for more details.
5. At the end of the installation procedure, the server is rebooted. Remove the installation media
and ensure that the system boots up properly.
6. If you installed the Red Hat Enterprise Linux server flavor, make sure you follow the instruc-
tions on how to subscribe the system to the Red Hat Customer Portal4.
If you install the CentOS Linux flavor, you may want to enable the Continuous Release
repository5to be able to get access to security updates as quickly as possible.
7. Enter the selected IP address in your web browser to access the Software Activation page. If
your host is using dynamic addressing, you can log in to the account created during installation
and issue the command ip addr to display the address assigned to the system.
Continue to chapter 3.4 for details on how to enable the 10G Software Probe system.
The kickstart will install CentOS Linux 7 or Red Hat Enterprise Linux 7 on the server. The
disks will be formatted and all contents lost. Make sure that any important data on the server
has been backed up before beginning the procedure.
3.3 Deploying in a Virtualized Environment
It is also possible to deploy the software in a virtualized environment. For optimal performance,
check the processor configuration of cores per socket on your host server and use the same
configuration setting of cores per virtual sockets on the virtual machine.
For accurate measurements, you must configure the data network interface card(s) in pass-through
mode on the host server.
Please follow the steps from chapter 3.2 when installing the software in the virtualized environment.
We recommended disabling any ‘Easy install’ or similarly worded option, and not selecting the
operating system type when initially creating the new virtual machine instance in your virtualization
environment. These options may override the installation instructions included in the provided
installation image, causing an incomplete installation.

VB330-SW 10G Software Probe User’s Manual version 5.5 15

Pre-built images for VMware (vSphere/Workstation/Player) are provided in OVA (Open Virtualization
Format Archive) format. These images contains a system already installed according to the steps
described in the previous chapter, with VMware Tools already installed and activated.
To deploy the image, you need to import it to the virtualization host, please refer to the documentation
of your virtualization environment for more details on how to do this.
If installed in a VMware vSphere environment, the machine should report back its network configu-
ration to the host environment. Please allow some time for it to do so, and then continue with point 6
as described in the previous chapter.
When logging in to the console of the pre-built images, the default password for the root user is elvis .
The same password is also used for logging in remotely using Secure Shell (ssh). Please change
the password for the root user after finishing the install , log in and use the passwd command to
do this.
3.4 Verifying Correct Initial Setup and Software Activation
Once the software has been installed and restarted all further configuration takes place through the
web interface.
1. Launch a web browser application on the management system.
Any web browser with support for JavaScript can be used to access the Software Activation
interface, one of the following are recommended:
• Google Chrome
• Mozilla Firefox
• Microsoft Edge
• Microsoft Internet Explorer 11 or higher
• Apple Safari
2. Type the IP address of the server in the browser URL field and press Enter .
The network settings should have been set when the operating system was installed. If the web
browser is unable to reach the web server, check the server’s network settings in the operating
system.
3. The Software Activation view should be displayed inside the browser. Software Activation
is password-protected, the user name is admin and the default password is elvis . The page
displayed should look similar to figure 3.1.
The password should be changed from the default. Expand the More options heading and
follow the instructions under Change password6.

Please note that it may take some additional time before the user interface of the activated
product becomes available. If you receive an error trying to access it, please wait for a few
minutes before trying again.
Note that it is not possible to activate the Software Probe and the VB7880 Advanced Content
Extractor on a single system at the same time.
To return to the Software Activation view to make changes, open the About — License tab in the
10G Software Probe user interface and click the link labeled Manage installed software.
By default, all web communication to and from the host running the 10G Software Probe is using
un-encrypted HTTP communication. Please refer to E Appendix: Enabling HTTPS for information
on how to enable HTTPS.
It is strongly recommended that the system time is configured to be synchronized against an
external NTP server. Please refer to F Appendix: Enabling NTP time synchronization for more
information on configuring time synchronization.
3.5 Initial Setup Troubleshooting
If you are having trouble bringing up the Software Activation interface, or the 10G Software Probe
web based management interface, verify the following:
• Verify that the client machine and the 10G Software Probe are configured on the same subnet
and that they have different addresses, or, if you use different subnets, verify that the routing
and gateways are set correctly on both the client machine and the 10G Software Probe.
18 VB330-SW 10G Software Probe User’s Manual version 5.5

• Make sure that the IP address of the gateway and the network interface are not the same.
• Verify that the appropriate Ethernet link indicators of the PC and the 10G Software Probe are
lit.
• Verify that web browser proxy settings are not interfering.
• Verify that local firewall settings on the PC are not interfering.
• Try rebooting the server and make sure all services start as expected.
• Clear the browser’s cache.
• Verify that the web server is running, by entering the command
systemctl status httpd
on the server’s command line. If it is not running properly, or you are seeing DNS lookup
failure errors, try issuing the command
echo "ServerName localhost" >> /etc/httpd/conf/httpd.conf
and then restart the server by issuing the command
systemctl restart httpd
• If you can reach Software Activation but the 10G Software Probe GUI is not working, enter
the command probehello on the server’s command line to verify that the VB330-SW services
are running. If services are not running, try re-installing the VB330-SW.
Please refer to D Appendix: Network configuration for more information on server network configu-
ration.
