Description
The Intinor Direkt receiver SDI receives video and audio from Intinor Direkt link via com-
puter networks, decodes the content and outputs it on the digital interface SDI. The live-
bradcasted material can be received from different senders and used for live-editing or dis-
tribution to TV viewers.
Intinor Direkt receiver is very easy to use and is configured in a web interface. Configurations
can be adjusted via a display and keypad.
Figure 1.1: Intinor Direkt receiver SDI
The Direkt receiver SDI is a robust construction with few moving parts. Intinor provides
support, can monitor links and help to ease network trouble shooting.
Similar to all Intinor products, the Direkt receiver SDI can be supplemented with options
and customizations. In this way, the customer is offered desired functionality without making
the unit complex and hard to use.

Technical overview
Intinor Direkt receiver SDI receives video, compressed using MPEG-2 or H.264, from com-
puter networks and outputs uncompressed digital video using SDI with embedded audio.
Figure 2.1: technical overview
2.1 Input
The Direkt receivers input is a RJ45-connector (TP) Ethernet 10/100/1000.
2.2 Transport
Intinor’s Direkt receiver receives MPEG transport streams over IP, either UDP or TCP.
UDP-streams can be unicast or multicast. Unicast streams are broadcasted to a single source
of reception while multicast streams can be received by several receivers if the network that
is used supports multicast.
When using TCP, the receiver buffers data and makes error corrections by requesting lost
packets to be resent. This technology adds latency (normally 10 seconds, but this can be
configured) but in return generates a more robust video link over the Internet and other
networks where packets are lost.
The Direkt receiver can be configured to listen for multiple transport methods simultaneously.

2.3 Decoding
Direkt receiver SDI can decompress video from MPEG-2 or H.264 format and audio in
MPEG-1 Audio Layer II (MP2) or AAC. It automatically detects which encoding technology
is used on the received data stream.
2.4 Output
The Direkt receiver outputs SDI with embedded audio . If blackbust sync is used, one picture
frame is stored in a “frame store” so that Direkt receiver can be synchronised with other
video sources.

3.2 Transport methods
Direkt receiver supports different technologies for receiving transport of video over IP net-
works.
3.2.1 UDP multicast
Multicast streams can only be used if it is supported in the network where it is to be
used for broadcasting of video and audio. This issue should be discussed with the network
administrator as this is usually not supported.
If there is support for multicast, it is usually possible to find multicast addresses and ports
on your own. Multicast is addresses between 224.0.0.0 to 239.255.255.255.

Intinor Direkt receiver SDI
User guide
Version 2.11.0 rev. 11624
Page 10 (27)
If multicast is used, it does not matter what IP-address the receiver is configured with.
Several receivers can be simultaneously linked to the stream.
3.2.2 UDP unicast
If there is no support for multicast, then unicast is to be used to stream to each receiver.
If the network capacity is inadequate, it is possible to broadcast via Intinor Direkt router,
please contact Intinor for more information.
IP-numbers on Direkt receiver must be known and configured in one of the following ways:
a) The Direkt receiver has a static IP-number, easily configured via display and keypad.
b) The Direkt receiver uses DHCP and always receives the same IP-number from the
DHCP-server on the local network. Contact the network administrator.
3.2.3 Stream TCP
Direkt link and Direkt router can “Stream TCP” (i.e. broadcast TCP-streams) to one or
several receivers. The receiver must be configured to receive the stream - TCP (receive).
The receiver buffers for a couple of seconds before it playing video and audio. If packets are
lost, there is a request to resend them. This means that only mayor network interruptions
renders video disturbances.
IP-number on Direkt receiver must be known and configured as for “UDP unicast” above.
UDP Unicast and Stream TCP are suitable transport methods
for live broadcasts.
The Intinor receivers can be configured to receive both UDP
unicast and Stream TCP. It detects the incoming signal, and no
configuration is needed to switch between transport methods.
3.2.4 TCP on request
If “TCP on request” is activated on the Direkt receiver, it is possible for one or more Direkt
receivers or Direkt routers, to actively request data streams - TCP (on request) from the
receiver. Error correction functions as described in “Stream TCP” above.
IP-numbers on the Direkt link must be known and configured in one of the following ways:
a) Direkt receiver has a static IP-number that can be easily configured via display and
keypad.
b) Direkt receiver uses DHCP, and always receives the same IP-number from the DHCP-
server on the local network. Contact the network administrator for more information.

3.2.5 Multiple transport methods at the same time
Starting with software version 2.10.0, the input on Direkt-mottagare can be configured for
multiple transport methods at the same time. When it does not have a input signal, it can
wait for both UDP and TCP and it does not need to be configured when the sender switches
from UDP to TCP.

3.3 ISS - statistics and supervision
ISS is Intinor’s system for statistics, supervision and alarms of Direkt link, Direkt router
and Direkt receiver. Units connects to a ISS-server and regularly sends information about
status on software, hardware, networks and disturbances in the incoming signal.
Figure 3.2: ISS for statistics and supervision

Intinor Direkt receiver SDI
User guide
Version 2.11.0 rev. 11624
Page 12 (27)
ISS eases installation and test - the user can log on by him/herself, or the Intinor support
can assist with this. Via ISS it is possible make sure that:
 The Direkt link’s network is functioning as intended.
 The Direkt link has an incoming signal (test picture or video from camera/editing).
 The Direkt receiver’s network is correctly configured and functioning as intended.
 The Direct receiver is receiving a video stream from the Direkt link.
When broadcasting live, it is valuable to know that the Internet has enough bandwidth.
Therefore, it is vise to test a broadcast to the Direkt receiver and to use ISS to make sure
that the received video stream does not contain interference.
If interference is detected in ISS, one or more of the following actions can be considered:
 Is it possible to upgrade the network connection, or in other ways fix it?
 Is it possible to accept lower video quality? - If so, switch encoding mode.
 Is it possible to accept longer delay? - If so, switch from UDP to TCP.
When the connection is functioning to satisfaction, it is recommended that the link remains
on until the actual broadcasting begins. Use ISS to look for interference; only accept a
few interferences per hour during a longer period of time. If there are more occurrences
of interference, follow the description above. Please, contact Intinor support for assistance
when needed.
Using ISS, it is also possible to configure alarms to be sent via SMS and e-mail if the
network connection is dropped, if there is no incoming stream, or if fans or hard discs are
not functioning properly.
If there is a problem with a unit, it is also possible to view graphs showing the temperature,
fan speed and voltage. This information can be useful when troubleshooting.
Intinor support is also able to view the unit’s configurations, status etc. from ISS, and
thereby assist in setting up configurations and upgrading. This is possible even when the
user is unable to connect to the unit’s web interface.
3.4 Access control
With access control, one can control on Direkt receiver which senders it accepts video streams
from.
Access control works for transport methods UDP multicast, UDP unicast and stream TCP
(see chapter 3.2). Without access control, Direkt receiver locks itself on the Direkt link which
it first receives from.
Intinor’s Direkt links can be identified in two different ways - either using IP numbers or
keys.
The advantage of using keys is that Direkt receiver can receive from a specific Direkt link
without knowing its IP number. The key for a Direkt link can be found under the system

Intinor Direkt receiver SDI
User guide
Version 2.11.0 rev. 11624
Page 13 (27)
tab in its web interface. For key identification to work, the difference in system time between
sender and receiver must be less than 30 seconds.
If multiple Direkt links, which are accepted on Direkt receiver sends simultaneously, it locks
on the IP number which comes first.
Access control is configured using the web interface (see chapter 3.8.2).
3.5 Test picture
To use a test picture, no video source is needed - it is generated and played out by Direkt
receiver. The standard test picture contains colored bars with information, current time and
time code created by Direkt receiver.
The test picture can be configured via the web interface with an image and text of your
choice (see chapter 3.8.3).
The test picture is activated automatically after five seconds if input signal is missing on
Direkt receiver(at shorter interrupts than five seconds, the picture is frozen).
3.6 Peak Programme Meter (PPM)
Direkt receiver has a built-in peak programme meter (the four diodes to the left of the
display). This can be used as a measure to make sure the sound levels are OK. Note that
the PPM should not be used as a precision instrument for in-measurement.
The peak programme meter is based on IEC 60268-18, and displays if the maximum value
of the left and right audio channel is above a certain level.
Peak Programme Meter (PPM)
PPM (dBFS)
⇒-12 (green) -9 (orange) -6 (red) Top diode can have three colors.
⇒-15 (green) -3 (red)
⇒-21 (green) -1 (red)
⇒-27 (green) Lowest diod indicates audio signal in
To comply with EBU-R68, the following must be valid:
 Calibration level (0dB) should correspond to -18dBFS - two green LEDs
 Maximumum level for normal program is -12dBFS - max three green LEDs
 Maximumum allowed peaks are -9dBFS - the top LED should never turn orange
If Direkt receiver detects a audio distortion, it blinks red with all
four diodes on the PPM.

The menu option makes the Direkt receiver connect to a name server on the Internet (8.8.8.8).
The Internet does not need to be operational in order to set up a video link in a private
network. Without the Internet, ISS and upgrade software doesn’t work.
Dynamic IP
Dynamic Internet configuration means that Direkt receiver, when starting up, asks the net-
work with DHCP which network configurations to be used.
If OK on Dynamic IP is pressed, the option to activate is given. This means that Direkt
receiver requests an IP-number from the network and uses it. Later, it is advisable to return
to “Current IP” to make sure that Direkt receiver received an IP-number. This configuration
is saved directly.
Static IP
When choosing static IP, Direkt receiver is configured with a static IP-number, a network
mask and a default gateway. The configurations are not activated until “Activate static IP”
is selected.

3.8 The web interface
Via the web interface, the user or administrator of Direkt receiver can perform all configu-
rations that are available via the keypad, and also the following:
 Customize the test picture
 Handle access control
 Adjust buffers for input streams
 Change password for logging on via the web interface
 Make a backup copy of all configurations
 Upgrade Direkt receiver’s software
 Restart Direkt receiver.
For information regarding the functions that also are available via the display, see chapter
3.7. This chapter describes the functionality that is available in the web interface, but not
via display and keyboard.
The web interface can be accessed using a web browser of your choice with secure http on
Direkt receiver’s number e.g. https://172.31.0.19
The first time the web interface is accessed, the web browser will ask if it should accept the
web server’s certificate. We recommend the option “Accept this certificate permanently”
(or similar). Possibly, a warning will appear stating that the domain name of the certificate
does not coincide with the web server. This is normally not an indication that something is
wrong.
Direkt receiver is delivered with the following user:
User: admin
Password: 1234
Intinor recommend that the password of admin is changed in
the web interface under the tab “System”. This is important if
Direkt receiver is accessible via the Internet.
Please note that if the network configurations are changed via
the web interface, or if a profile is activated with other network
configurations, it is possible that the connection to the Direkt
receiver is lost. If this happens, it is possible to view the “Current
IP” using the keypad. It is then possible to re-connect using the
instructions above.
3.8.1 Status
Here is status information concerning the unit, its input and output and destinations. For
the input, it is possible to view e.g. picture format and aspect ratio.

Managing settings
Here, the user can make a backup copy of all of Direkt receiver’s settings. It is saved in
XML-format and can be sent to Intinor for analysis, if troubleshooting is needed.
Software upgrade
If Direkt receiver is connected to the Internet, the software can be upgraded using Intinor’s
servers.
Always make a backup copy of Direkt receiver’s settings before
a software upgrade
Click on the link “upgrade the software...” to get to the upgrade-page.
Click on “Show current version numbers” to receive information regarding available soft-
ware’s from Intinor’s web site. Beta software contains new, and somewhat untested, func-
tionality. It is recommended to primarily use stable software.
Normally, the user can upgrade to the newest stable- or beta- software by clicking on the
corresponding button. Advanced upgrade is only used in exceptional cases, in dialog with
Intinor. This can be the case, for example when new functionality is developed for a specific
cause.
Upgrades are completed in approximately 30 seconds and are followed by a restart. Do not
interrupt Direkt receiver while upgrade is in progress (shown on the display).
Upgrade via the web interface requires that Direkt receiver has access to the Internet and is
not blocked by a firewall (see chapter 4). If this is not possible, Intinor can provide a USB
memory stick for software upgrade.
System restart
Restart should never be needed. However, it can be useful sometimes for trouble shooting
purposes to be able to restart Direkt receiver.
Restart all streams takes just a second and restarts engine on Direkt-mottagare. The video
and audio decoders are restarted and the output has a short disruption
Full system reboot means approximately the same as disconnect and connect the power cord
to Direkt-mottagaren.

Chapter 4
Firewalls
If broadcasting with Direkt link is performed within an internal network, such as a local
area network (LAN), or a Metropolitan area network (MAN), it is often necessary to handle
firewalls. In order to get access to the control room of a TV-channel, or get outside a
cooperation network, it can be necessary to configure a firewall to allow traffic.
Intinor’s engineers aid the configuration, and gives hints as how
to configure firewalls.
Figure 4.1: Example with firewalls
RTMPT requires higher bandwidth so that the risk for interup-
tions in the stream is higher. RTMPT from Direkt link also does
not work with all streaming servers. Because of this, try RTMP
first.
4.1 To send UDP or TCP (live broadcasting)
Usually, no configuration of firewalls is needed in order to broadcast IP-streams (UDP or
TCP) from a Direkt link. Most networks allow outgoing IP traffic by default. In other cases,
configuration of the firewall is required so it allows outgoing data traffic to a particular
destination port e.g. 4001 (it is a good idea to open up for both UDP as well as TCP).
A receiver that receives an IP stream and is located behind a firewall must have a static
IP number. The firewall should be configured in such a way that it allows request from a
specific port to the receiver (preferably for both UDP as well as TCP).
