Technical overview
Intinor Direkt link 300 and 400 series inputs video and audio from a SDI (SD/HD) or HDMI input, compresses the content with H.264, and broadcasts one or more identical video streams over Internet and other computer networks.
Figure 3.1: technical overview
3.1 Input
The following inputs are present on Direkt link 300 and 400 series:
SDI (SD/HD) with embedded audio
Direkt link detects if the input is SDI or HDSDI
Some older versions of Direkt link are lacking hardware sup­port for HD - also if they are upgraded to the newest software
- please contact us for hardware upgrades
Latest generation Direkt link 400 rack/rack+ also have sup­port for 3G-SDI in.
HDMI with embedded audio (only on mobile units)
3.2 Video and audio mixer
Direkt link has a simple built in video mixer for two purposes:
User Guide
Version 3.0.0 rev. 15412
Page 11 (52)
1. Automatic switch to the input that first receives an input signal
2. Manual video mixer controlled bu the user via browser or keypad – even mix remotely if the latency over public internet is acceptable
3.3 Scaling
Direkt link scales incoming video- and audio formats to what the encoder is configured to work with. This includes going from interlaced to progressive (de-interlacing) and frame-rate conversions (e.g. from PAL to NTSC).
3.4 Encoding
Direkt link 300- and 400 series has the ability to compress video in H.264 format (MPEG-2 as an option), and audio in the formats ACC and MPEG-1 Audio Layer II (MP2). There are several pre-configured settings for encoding. Advanced users have the option to also customize own settings for encoding.
3.5 Transport
Intinor Direkt link sends MPEG transport streams over TCP/IP, UDP, RTP, RTP + FEC, UDP bonding or RTMP (UDP, RTP and RTP + FEC only on 400 series).
Transport methods are described more detailed in chapter 6.6.
3.6 Output
The Direkt link outputs via a RJ45 (TP) Ethernet 10/100/1000 connection. The output is called “IP1”. The best video quality is possible if the Direkt link is used over a dedicated connection between locations where a high bandwidth can be guaranteed. It is also possible to broadcast over the Internet, especially when using TCP for error correction or RTP + FEC for low latency applications.
3.7 HDMI out for monitor - only on mobile
Direkt link mobile has HDMI out for monitoring of outgoing video stream from encoder. If one wants to use the built-in video mixer, it is possible also to have a multiview on monitor output to see both inputs and output signal with PPM for audio level out.

Getting started - send to receiver
The following instruction describes the process of getting started using the Direkt link for broadcast receiver, in less than 15 minutes.
4.1 Recommended test setup
To perform the test you need:
Direkt link (sender)
A receiver - for example one of the following:
a) Intinor Direkt receiver b) Intinor Direkt router
An account on ISS with access to Direkt link and receiver to remote control the units
- see chapter 6.8
A TV, monitor, projector or other device that fits the output of the receiver - or someone who can watch if the receiver is located elsewhere
A video source with outputs which fits Direkt link - see chap. 3.1
If you don’t have access to a receiver, you can use one of Intinor’s Direkt router and use VLC to pull the stream to your desktop ­contact Intinor support

User Guide
Version 3.0.0 rev. 15412
Page 13 (52)
4.2 Preparations
4.2.1 ISS
Log in to ISS and verify access to Direkt link and receiver.
4.2.2 Receiver
To use Direkt link, a receiver is required (see chapter 7). This is usually installed in the control room or similar and needs to make accessible if located behind a firewall, see chapter
8.
If the receiver is a Direkt receiver or Direkt router from Intinor, it should be available in ISS. It shows “no input signal” when it is ready to receive. By clicking on its name in ISS, one can see which port/ports is listens too and if access is limited with access control. Usually, it’s to the receiver’s external IP number (to the left if ISS shows two) one should send the video stream.
4.2.3 Direkt link
Connect the Direkt link using IP1 on a network connection where outgoing traffic is not blocked by a firewall. Verify that it’s connected to ISS.
4.3 Implementation
1. Remote control Direkt link’s web interface from ISS. Log in with username=admin, password=1234 of it’s not changed.
2. Add a new TCP stream under active settings, encoder, destinations. Set IP number and port (usually 6010) to the receiver. Activate and confirm.
3. If the receiver receives the video stream, Direkt link shows “streaming ok”, “x megabit/sec out” where x is more than 0.
4. On ISS, the receiver should now show “no errors” (you should see a green bar) and the video output on the receiver should output video.
If everything works fine, you can begin experimenting with different encoding modes and other transport methods. Proceed with the user manual. Good luck.

ble shooting
Figure 6.1: Different user interfaces
6.2 Basic videomixer
Direkt link mobile has a basic video mixer built-in.
6.2.1 Auto mode
When Direkt link starts up, the video mixer is in auto mode. In this mode, it selects input signal from SDI primarily and HDMI secondary.
If input signal is missing, video mixer has no output signal
If SDI signal is present, video mixer will output audio/video from SDI
If HDMI signal is present and SDI signal missing, video mixer will output audio/video from HDMI
User Guide
Version 3.0.0 rev. 15412
Page 17 (52)
If Direkt link has input signals on both SDI and HDMI, the user can choose to enter manual mixing mode by pressing HDMI in web interface or on a physical mixer control (accessory). See below
6.2.2 Manual mode
Figure 6.2: mixer control (option)
Direkt link with video mixer in manual mode is controlled by the user from web interface or physical mixer control.
Audio is always mixed from SDI in
If input is missing on both inputs, Direkt link returns to auto mode
6.3 Multiview and HDMI out
Intinor Direkt link mobile can show multiview or encoded video on HDMI out.
6.4 Encoder
Direkt link has at least one encoder to compress video- and audio inputs. Two encoders is an option which makes it possible to:
1. Stream two different qualities
2. Stream one quality and simultaniously record another
3. Send two different streams (from two different sources)
With only one encoder, there is no reason to connect it to anything but the built-in video mixer. With two or more encoders, it’s possible to for example stream from video mixer but record from SDI. Therefore, the encoder can be connected to SDI in, HDMI in or video mixer.
6.5 Encoding modes
Direkt link has several built in encoding modes for broadcasting.

The advanced user can also create custom encoding modes via the web interface of Direkt link. It is possible to select custom encoding modes in the lists in both user interfaces.
6.6 Transport methods
Direkt link supports different technologies for broadcasting video to one or several receivers over IP networks.
User Guide
Version 3.0.0 rev. 15412
Page 20 (52)
6.6.1 UDP multicast (only available for 400 series Direkt link)
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.
If multicast is used, it does not matter what IP-address the receiver is configured to. Several receivers can be simultaneously linked to the stream.
UDP multicast is a suitable transport methods for distribution to many receivers on the same local network (e.g. IPTV appli­cations and internal distribution on a LAN).
6.6.2 UDP unicast (only available for 400 series Direkt link)
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 receiver must be known and configured in one of the following ways:
a) The receiver has a static IP-number. Intinor Direkt receiver and Direkt router can be
configured easily via display and keypad.
b) The receiver uses DHCP and always receives the same IP-number from the DHCP-
server on the local network. Contact the network administrator.
6.6.3 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 major network interruptions result in video disturbances.
The size of the TCP buffer can be configured on the receiving unit. A value between 0.3 and
0.5 is good for an interview with studio feedback. For a transmission during a longer period of time without feedback, 3-10 seconds is recommended.
IP-number on receiver must be known and configured as for “UDP unicast” above.
User Guide
Version 3.0.0 rev. 15412
Page 21 (52)
6.6.4 RTP and RTP + FEC (only on 400 series)
RTP (Real Time Protocol) is a layer on top of UDP for video and audio in realtime. It allows the receiver to handle in a better way certain types of errors during the transmis­sion. FEC includes extra data which allows the receiver to handle small packet loss without compromising or affecting the image quality.
Both RTP and FEC requires multiple UDP ports in the range between transmitter and receiver. We recommend 10 ports reserved starting by an even number. For example, UDP port 6010-6019 for the first RTP stream and 6020-6029 for the next.
RTP and FEC are send as UDP. The Intinor receivers are therefore configured to receive a UDP streams and detect the RTP and FEC used on top of the UDP packets in the stream.
FEC provides error correction over the Internet with lower delay than TCP as described above. However it requires more bandwidth and also adds some delay compared to UDP or RTP without FEC. The advanced user can adjust the FEC settings in the web interface to achieve low latency or robust link which can handle more dropped UDP packets in a row.
6.6.5 Network bonding
Network bonding is an extended network functionality for Direkt link which allows the capacity from multiple physical connections to be aggregated. The sender can use several Internet connections at once to increase the capacity. It can also be used for redundancy. Network bonding means the Direkt link can use multiple 4G/LTE-modems and land-line Internet connections in different combinations.
UDP Unicast, RTP, FEC, UDP bonding 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.
6.6.6 RTMP for web TV
Direkt link can also send streams in RTMP (Real Time Messaging Protocol) and RTMPT (RTMP over HTTP - makes it easy to send through firewalls) format. By using RTMP, one can send directly to a number of different providers of streaming for web TV. RTMP can only be configured using the web interface.
6.6.7 Network Failover
Direkt link sends on the first interface which has Internet access (or all interfaces if protocol UDP bonding is used). A Direkt link can be connected using IP1 to one Internet connection
User Guide
Version 3.0.0 rev. 15412
Page 22 (52)
and IP2 to another at the same time. If the first network works, it will send using it, but if it’s not connected or doesn’t work, it will send over IP2. If IP1 Internet fails during a transmission, Direkt link will switch within a few seconds to transmit over IP2. An ongoing transmission using IP2 will not switch to IP1 as long as IP2 works.
Also the connection to ISS for management will failover to the first interface with Internet connection.
A network interface which is not connected to Internet is tested every 10 seconds. If the interface has link (or modem connected) the following connections are tested:
1. iss.intinor.se port 22017
2. iss.intinor.se port 80
3. 8.8.8.8 port 53
If any of those servers accept the connection, the Internet is considered to work on the interface and the test is finished.
6.6.8 TCP on request
If “TCP on request” is activated on the Direkt link, it is possible for one or more receivers, to actively request data streams - TCP (on request) on the receiver. Error correction functions as described in “Stream TCP” above.
IP-numbers on Direkt link must be known and configured in one of the following ways:
a) A static IP-number that can be easily configured via display and keypad. b) It uses DHCP, and always receives the same IP-number from the DHCP-server on the
local network. Contact the network administrator for more information.
If encoding is not adaptive, it is possible to use multiple trans­port methods - The Direkt link can broadcast TCP streams to some receivers, while sending an RTMP stream and deliver TCP-streams on demand to other receivers.
6.6.9 Changing transport method
It’s easy to change trasport method between UDP, TCP, RTP, RTP+FEC and UDP bonding. List streams using display/keypad, choose a stream, press ok again to change transport method, destination IP number or port.
6.6.10 Summary of transport methods
6.7 Adaptive bitrate
Adaptive bitrate in a network functionality for an interruption-free transmission between sender and receiver. It means that the sender adapts to the current capacity for the Internet

connection/connections in use, which happens at once. Adaptive bitrate provides safty and simplicity for the user, who can focus on the live broadcast instead of worry about the Internet connection to maybe loose capacity.
Adaptive bitrate can only be used for one stream using transport method TCP or UDP bonding.
6.8 ISS - system for statistics and supervision
ISS is Intinor’s system for statistics, supervision, alarms and remote control 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.
Connection to ISS uses failover in the same way as outgoing video streams. See chapter
6.6.7.
Figure 6.3: ISS for statistics and supervision
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 is not blocked by a firewall.
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 Direkt receiver is receiving a video stream from the Direkt link.
When web TV is sent using RTMP one can not supervise the receiver using ISS. But ISS shows warnings in case not all data that is sent arrives at the receiver / CDN. Check for warnings (purple color).
When broadcasting live, it is valuable to know that the Internet has enough bandwidth. Therefore, it is wise to test a broadcast to the Direkt receiver and to use ISS to make sure that the received video stream does not contain interference.
User Guide
Version 3.0.0 rev. 15412
Page 24 (52)
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 or activate adaptive bitrate
Using UDP? Add RTP+FEC. Is it possible to accept longer delay? - If so, switch 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 disks 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.
From ISS, a unit can also be remote controlled, also if it’s behind a firewall. The ISS user can use the local web interface if access is confirmed from the display or web interface. The need for confirmation can be disabled by a non-user system configuration if an easier behavior is preferred.
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.
6.9 IP1, IP2 ...
Direkt link has two network interfaces on the back marked IP1 and IP2.
IP1 should be connected to the Internet so that Direkt link can connect to ISS and send
IP streams. The IP number for IP1 shows in ISS, on the display and that is used when accessing Direkt link’s web interface via IP1
IP2 is per default configured as management - a service interface that can be used to
activate and use Internet access, for easy access to ISS and web interface on Direkt link. IP2 can also be configured as an extra Internet connection for network failover or bonding.
4G Mobile Direkt link has a built-in LTE/4G modem which can be handled via the web
interface. 4G can be used for network failover or bonding.

6.9.1 More optional interfaces
Direkt link mobile can be equipped with the option “Multiple 4G”. This includes a modem box, providing additional two LTE/4G modems.
Direkt link can also be equipped with additional wired network interfaces as an option.
6.10 IP2 as management
With IP2 as management, Direkt link act as a network router. If compared to a home Internet router, IP1 is WAN and IP2 is LAN. By connecting units on IP2, Internet can be accessed and also settings on Direkt link. To do this IP2, must be in management mode (default). Do not connect IP2 to your office LAN - it will create conflicts with your DHCPserver/router.
Figure 6.4: IP2 can be used for configuration and supervision
6.10.1 Log on to the Internet
A computer connected to IP2 can get access to the Internet through Direkt link. If Inter­net access requires log in with user name and password (common at hotels and conference centers), it’s possible to open a web browser on the computer and log in for Direkt link.
6.10.2 Supervise using ISS
Go to iss.intinor.se using the web browser and log in with user name and password from Intinor. Then you can supervise and trouble shoot the units you have access to.

6.10.3 Configure Direkt link
Log in to Direkt link by connecting to its IP-number (check network -> Current IP using display and keypad) using a web browser to access local status and all configuration.
6.10.4 Watch outgoing video stream on computer
Use VLC and watch outgoing video stream using TCP according to chapter 7.3. TCP on request must be active on Direkt link.
6.11 Record files
Direkt link can record video files on one of the following:
a) Internal hard disk - option b) Storage unit with USB support
Internal hard disk is more suitable in combination with options such as automatic file syn­chronication to FTP server, share files to local network etc. A USB storage unit in easy to move to another computer for post production or other use.
Menues for recording and file handling appears in display and web interface when storage unit is available.
Recording means that the video stream Direkt link is broadcasting also is stored on the storage unit. “Storage unit” can be a hard drive, a USB-memory, P2-reader, NAS-RAID etc. One limitation is that Direkt link only communicates with one USB unit, this being the first unit that is detected.
The following file systems are supported on Direkt link:
File system Support in operating sys-
tem
Max file size
FAT32 Windows, Mac, Linux Max 4GB NTFS Windows, Linux Larger than 4GB ext3 Linux Larger than 4GB
Formating can be carried out from display or web interface.
Recording is activated via display or web interface. Or using an external mixer control (option). Direkt link creates file names based on the time when the recording was started.
Tip - set Direkt link’s clock using the web interface if ISS is not used.
When Direkt link has recorded 1 GB (default) it begins recording to a new file. The size and path of generated files can be changed from the web Interface.
Files are saved as MPEG-transport streams (MPEG-TS) and/or in Flash format (.flv) and can be played on a PC with, for example, VLC see chapter 7.3).
User Guide
Version 3.0.0 rev. 15412
Page 27 (52)
Files from Direkt link can also be sent to streaming provider for web TV.
When recording is in progress the menu option changes name to ”stop recording”.
6.12 Test picture
The test picture is used to easily test that video and audio is sent between the Direkt link and receiver.
To use a test picture, no video source is needed - it is generated and encoded by Direkt link. The standard test picture contains colored bars with information, current time and time code created by Direkt link.
The test picture can be configured via the web interface with an image and text of your choice (see chapter 6.16.4).
The test picture can be activated from the display/keypad or the via web interface. From the web interface, Direkt link can be configred to encode test picture, black or nothing if input signal is missing. If nothing is broadcasted, the network is not under load.
6.13 Profiles and active settings
A profile is a collection of settings for, among other things, easing broadcasting from different locations when Direkt link is used for mobile production. Profiles consist of configurations for network, streams and encoding modes.
From the web interface, profiles can be added, changed and renamed.
When Direkt link is used for mobile production and is moved between different locations, it is recommended that profiles for each location are created in advance using the web interface. The keypad is primarily used to select a profile and make minor adjustments on location.
6.13.1 The following is included in a profile
In a profile all configurations are included, except test picture on/off, recording to storage medium on/off and customized test picture.
6.13.2 Active settings
The configurations that Direkt link uses are active settings. When the user chooses to use a profile with a particular name, the settings of the profile is copied to the active settings of
User Guide
Version 3.0.0 rev. 15412
Page 28 (52)
Direkt link, which the starts using them. Current settings are removed and replaced by the settings defined in the profile.
6.13.3 To change active settings
The user can select a particular profile and change e.g. IP-number or stream quality. This is a change to the active setting, but does not affect the profile that the settings come from. Thus, the user does not mistakenly “mess up” the profile with the keypad. The display displays “Manual conf.”.
6.13.4 Save as a new profile
If the user saves a new profile, the current settings are stored. The first new profile that is saved gets the name “new profile #1”, the other one “new profile #2” and so on. Via the web interface it is possible to edit, rename or delete the new profiles.
6.13.5 Edit profile
Profiles can only be edited and renamed via the web interface.
6.14 Peak Programme Meter (PPM)
Direkt link 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
User Guide
Version 3.0.0 rev. 15412
Page 29 (52)
If Direkt link detects a audio distortion, it blinks red with all four diodes on the PPM.
6.15 Configure via display and keypad
The display on Direkt link displays status information and can, together with the keypad, be used to configure.
With the keypad, the user can choose settings from a profile, change the active settings and store configurations as a new profile. It is also possible to turn the test picture and recording on and off. These configurations are not saved in profiles, they are global configurations.
With the keypad, it is not possible to change the profiles, but only the active settings.
6.15.1 Status information
Figure 6.5: status mode
When the Direkt link starts, the display is in status mode. In this mode, the status information is displayed (profile name, number of active/configured streams, current bit rate out).
Multicast streams are always broadcasted.
Unicast streams are broadcasted if there is a receiver with the IP­number that the stream is aimed to, or a router in the net between Direkt link and the receiver. The receiver does not need to look at the stream, only to be turned on with the current IP-number.
6.15.2 Main menu

Test Internet Conn.
The menu option makes the Direkt link connect to a name server on the Internet (8.8.8.8). Also connection to ISS is tested. 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 software upgrade don’t work.
Static IP
When choosing static IP, Direkt link 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.
Dynamic IP
Dynamic Internet configuration means that Direkt link, when starting up, asks the network 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 link requests an IP-number from the network and uses it. Later, it is advisable to return to “Current IP” to make sure that Direkt link received an IP-number. This configuration is saved directly.

Modem
Under this sub-menu, connected 4G/LTE-modems are listed. Direkt link shows if the modem is connected to 3G or 4G, which operator and current signal strength. It’s also possible to view SIM ICCID, enter PIN/PUK code and force 4G. A modem foreced to 4G will not wry to switch to 3G. Often, a bad 4G net provides better capacity than 3G. Direkt link remembers PIN/PUK codes for multiple SIM cards, so if one often switch between two cards it knows, codes don’t have to be changed.

6.15.4 Encoder:Streams
Direkt link plays one or more video streams over computer networks. An explanation for the difference between stream types is available in chapter 6.6. The term UDP-stream implies both UDP unicast and UDP multicast.
The following menu options are present under the menu “Encoder:Streams”.
Encoder:Streams
Encoding mode Choose an encoding mode for all video streams Adaptive bitrate activate/deactivate adaptive bitrate List streams List, modify and de-activate streams that Direkt link is con-
figured to broadcast. New UDP stream Add an UDP stream New TCP stream Add a TCP stream TCP on request Activate TCP on request and choose the number for the
TCP port. New RTP stream Add an RTP stream New RTP+FEC stream Add an RTP+FEC stream New UDP bonding stream
Add an UDP bonding stream
UDP smoothing buffer adjust smoothing buffer for UDP streams
Encoding mode
Choose built in encoding mode. View chapter 6.5 for description of encoding modes. If own encoding modes are available, these are located in the sub-menu “custom”.
List streams
Show which streams that Direkt link is currently broadcasting. Active streams are marked with a star. If the user press OK once on a stream, more information is shown. Another press on OK renders the option to activate/de-activate or change the stream.
New UDP stream
Figure 6.8: new stream
Add a new UDP-stream by configuring IP-number (or multicast address) and port. When “activate stream” is selected and con­firmed, Direkt link begins to broadcast the new stream.
User Guide
Version 3.0.0 rev. 15412
Page 33 (52)
New TCP stream
Add a new TCP stream by configuring IP-number and port to the receiver. When “activate stream” have been selected, the Direkt link begins broadcasting the new stream.
TCP on request
Activate Direkt link to listen for requests and broadcast TCP streams on requests. Also, specify which TCP port that is to be used.
UDP smoothing buffer
The bit rate that is generated by a video encoder changes during a second. The UDP smoothing buffer reduces the variations and the risk for packet loss in the network. A smaller buffer creates less delay. If the network has much higher capacity than the Direkt link needs, this buffer can be set to 0.01.
UDP smoothing buffer is relevant for transport methods UDP, RTP, RTP+FEC and UDP bonding. The setting in not present on Direkt link 300-series. On those models, it’s always auto for UDP bonding

6.15.7 Advanced
A PAL SD input signal can have either 4:3 or 16:9 aspect ratio. This does not affect the resolution of the video stream. The setting only controls ratio information in the MPEG­stream so that the receiver can handle it correct. On several receivers it is possible to configure aspect ratio, in which case the configuration of Direkt link does not matter. Direkt link never adds black borders known as letter or pillar box.
Video input / Aspect ratio (SD)
auto Direkt link tries to detect the aspect ratio from video input signal.
If no supported aspect information is available, it falls back to 16:9 16:9 Force Direkt link to handle the video input as 16:9 aspect ratio 4:3 Force Direkt link to handle the video input as 4:3 aspect ratio
The built-in encoding modes can be adjusted. The menu option is not available if the Direkt link is not configured to broadcast with custom encoding mode. Do not forget to save in order to execute the changes.

Built-in encoding modes
Stereo/mono Stereo broadcasts on dual audio channels and needs more band-
width for audio. Mono (left + right) puts together the channels
and is suitable if two channels are available, but when broadcasting
on only one audio channel is desirable to save bandwidth. Mono
(left) and Mono (right) means that Direkt link only broadcasts
from one audio channel. Audio tracks It is wise to de-activate unused audio tracks to save bandwidth.
6.15.8 Start/stop recording
Start recording is located in the menu if a storage unit is connected. For more information about recording, see chapter 6.11. When recording is in progress the menu option changes name to “stop recording”.

via display and keyboard.
The web interface can be accessed using a web browser of your choice with secure http on Direkt link’s number e.g. https://192.168.0.1
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.
Units can be remote controlled via the local web interface from ISS. This makes it easy to access units also when they are located behind a firewall. Normal behaviour is that remote control must be accepted via display/keypad, but Intinor can configure units to always allow remote control from specific ISS users. Contact Intinor support
Direkt link 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 link 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 link is lost. If this happens, it is possible to view the “Current IP” using the keypad and then re-connect using the instructions above.

Software upgrade
If Direkt link is connected to the Internet, the software can be upgraded using Intinor’s servers.
Click on the link “upgrade the software...” to get to the upgrade-page.
Click on “Show current version numbers” to receive information regarding available soft­ware’s from Intinor’s web site. Beta software contains new, and somewhat untested, func­tionality. 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 link while upgrade is in progress (shown on the display).
Upgrade via the web interface requires that Direkt link has access to the Internet and is not blocked by a firewall (see chapter 8). 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 link.
Restart all streams takes just a second and restarts engine on Direkt link. The video and audio encoders are restarted and all output streams have short disruptions.
Full system reboot means approximately the same as disconnect and connect the power cord on Direkt link.
6.16.5 Files
Here, it is possible to list, download and delete files from a connected storage unit. The page for file management is only available if a storage unit is connected to Direkt link.
Under the tab “recorded files”, only files that have been recorded using Direkt link is listed. For recorded files, additional information is available, to show date of recording and recording length.

Receivers
Streams from Intinor Direkt link can be received and displayed using Intinor Direkt receiver and Direkt router, digital TV boxes f¨or broadband-TV, PC or receivers from other vendors, for example miniCASTER or Satmission.
7.1 Intinor Direkt receiver
The Intinor Direkt receiver with SDI outputs can be used to receive streams from all models of Direkt link and Direkt router. The Intinor Direkt receiver has the following advantages:
+ Easy to configure and administrate. + Support for ISS - Intinors system for statistics, supervision and alarms. + Can receive UDP unicast and multicast from Direkt link and other MPEG-encoders. + Support for error correction using TCP from Direkt link and Direkt router. + Support for error correction using FEC from Direkt link and Direkt router. + Support for adaptive bitrate from Direkt link and Direkt router.
Figure 7.1: Intinor Direkt receiver
7.2 IP-TV boxes from Amino
Figure 7.2: Amino-box
Intinor sells, and gives support for, IP-TV boxes from Amino that can be used as receiver for a Direkt link. Amino IP-TV boxes cost less compared to the Direkt receiver, but has the following disadvantages:
– Cannot be configured using display and keypad. – Cannot be controlled via ISS (see chapter 6.8). – Cannot receive TCP for error correction. – Are not available with balanced audio or SDI output.
Amino IP-TV boxes are mainly recommended for Closed Circuit TV where easy connection to different TV sets is possible.

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 8.1: Example with firewalls
8.1 To send web TV using RTMP (Adobe)
Usually, no configuration of firewalls is needed in order to broadcast web TV streams (RTMP) from a Direkt link. Most networks allow outgoing IP traffic by default. In other cases, the firewall can be configured for outgoing data on TCP port 1935, which is used by RTMP.
If configuring the firewall is not possible, one must change to RTMPT in Direkt links web interface - change RTMP to RTMPT in “RTMP URL”. Then Direkt link sends RTMP over HTTP on port 80, which firewalls always use to pass out.
Feel free to follow the instructions below to send web TV:
1. Try to send RTMP using settings from streaming provider.
2. If the stream does not come through, try to open TCP port 1935 out on the firewall.
3. If it is not possible to open the firewall, change to RTMPT using Direkt links web interface.
User Guide
Version 3.0.0 rev. 15412
Page 44 (52)
RTMPT requires higher bandwidth so that the risk for interup­tions in the stream is higher. RTMPT from Direkt link also does not work with all streaming servers. Because of this, try RTMP first.
8.2 To send UDP, RTP, RTP+FEC, UDP bonding 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. 6010. When RTP or UDP bonding is used, a range of ports is required where the first port has an even number. Iit is a good idea to open up 10 ports in a row (6010-6019) for both UDP as well as TCP to make it simple to change protocol later.
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 series to the receiver (preferably for both UDP as well as TCP).
Feel free to follow the instructions below to broadcast IP-streams (repeat the instructions for each receiver):
1. Choose a port range to broadcast to. The ports must be available on firewall R e.g. 6010-6019.
2. Make sure the receiver have a known IP number e.g. 172.31.0.19.
3. Make sure the firewall R lets through UDP and TCP traffic on port 6010-6019 to
172.31.0.19.
4. Find out the receivers external IP number (e.g. 194.132.19.1). It is possible to use ISS to find this out.
5. Configure the Direkt link to broadcast to the receiver’s external IP number and selected port.
6. If no stream reaches the receiver, it can be due to firewall S not letting out UDP or TCP traffic on the selected port. Check if this is the case.
8.3 TCP on request (distribution)
A Direkt link that is configured with TCP on request receives requests on a specified TCP port, e.g. 5040. If the Direkt link is behind a firewall it has to have a static IP number (see chapter 6.6.8) and the firewall must be configured to let through requests to a specific TCP port to the Direkt link.
To get a receiver to receive TCP streams, it is usually not necessary to make configurations, even if it is behind a firewall. If this is not the case, the firewall should be configured to let through requests pointed to a specific TCP port e.g. 5040.
User Guide
Version 3.0.0 rev. 15412
Page 45 (52)
Feel free to follow the instructions below to allow the receiver request TCP:
1. Choose a TCP port to request from. The port must be free on firewall S e.g. 5040.
2. Make sure Direkt link has a known IP number e.g. 192.168.0.19.
3. Make sure firewall S lets through TCP traffic on port 5040 to 192.168.0.19.
4. Find out Direkt link’s external IP number (e.g. 72.5.104.61). It is possible to use ISS to find out the external IP number.
5. Configure the receiver to request TCP from Direkt link’s external IP number and selected port.
6. If no stream gets to the receiver, it can be due to firewall R not letting out traffic on the selected TCP port. Check if this is the case.
8.4 Upgrade and ISS
Upgrade and ISS (see chapter 6.8) connect with TCP to Intinor’s servers. Usually, no configuration of firewalls is required for this operation. In other cases, make the following configuration:
Upgrade TCP port 9022 out to Intinor’s upgrade server (upgrade-
direkt.intinor.se)
ISS TCP port 22017 out to ISS (iss.intinor.se)
Starting with software version 2.12.0, all Intinor Direkt units, which are blocked by a firewall try to connect to ISS using HTTP, which often works. Upgrade can be performed from a USB memory.
8.5 Web interface
To access the web interface on the Direkt link, Direkt router or Direkt receiver through a firewall, it is required that the unit has a static IP number and that the firewall is set to let through requests to TCP port 443 on the specific unit. To download files from Direkt link or Direkt router it is required that TCP port 80 is opened.
Starting with software version 2.12.0, all Intinor Direkt units can be remote controlled from ISS. Because of this, opening for web interface is not necessary. Files can not be downloaded using remote control.

8.6 Cheat sheet - receiver for live broadcasting
The firewall used together with Direkt receivers or Direkt routers for direct broadcasting is normally configured only once.
If the receiver can be given a public IP number on the internet, no firewall is needed.

* Do not forget to change admin password on the receiver.
8.7 Cheat sheet - Direkt link for live broadcasting
If the Direkt link can be assigned a public IP number, no firewall configuration is needed.
If the Direkt link is located on the Internet behind a “friendly” firewall, which is open for outgoing traffic, no firewall configuration is needed.
If the Direkt link is located on the Internet behind a “strict” firewall, which blocks outgoing traffic, the following firewall configuration is required:
ISS TCP port 22017 out Video stream out any, e.g. TCP and UDP port 6010-6019 out

Trouble shooting
9.1 Use ISS
Figure 9.1: ISS
Direkt units connects to ISS via TCP port 22017. If that fails, they try instead with HTTP over port 80 (works through almost all firewalls). If a Direkt unit is forced to connect using port 80 is displayed as a warning in ISS. It usually means that the firewall must be opened for it to send video. See chapter 8.
Use ISS to make sure both Direkt link and Direkt receiver is con­nected. If a unit is gray in ISS, it can be due to the following reasons:
1. The network does not function properly, or is configured in an incorrect way (see the troubleshooting below).
2. The unit is behind a firewall that blocks the connection to ISS. If this is the case, the possibility is that it also lacks the ability to broadcast a video stream (see chapter 8).
3. Direkt link and receiver is connected via private LAN or VPN without Internet con­nection. It is possible to use Direkt link in this way, but it is not possible to use ISS for monitoring and troubleshooting.
If the network functions to satisfaction, but no video stream is coming from the receiver, please continue troubleshooting streams according to section 9.3.
9.2 Network
Access the network menu with the display interface located on the unit. Make sure the network is functioning on the unit with the gray color in ISS by following the instructions below:
1. Display network status - IP1 shall show 100 Mbps, full or similar. If this is not the case, check the network cable, network outlet, and network switch that the unit is connected to.
2. Note if the unit is configured to dynamic or static IP by checking which of the following menu options are marked with *.
a) If the unit uses “Dynamic IP” check its “Current IP” on the unit. If it does not
have an IP number, it does not receive an IP number from any DHCP server.
b) If the unit has static IP number, make sure IP number, network mask, and gate-
way is functioning correctly.
User Guide
Version 3.0.0 rev. 15412
Page 48 (52)
3. If the unit is connected to the Internet (i.e. not via private LAN or VPN), make sure the network connection is functioning with “test Internet” in the network menu. If the unit is not connected to the Internet, try to connect to its web interface with a computer (see chapter 6.16).
If all above is functioning, but the unit fails to connect to ISS, it is probably hindered by a firewall that needs to be opened (see chapter 8).
9.3 Streams
Intinor support can view the unit’s configurations in ISS. In this way, Intinor can easily make sure Direkt link is broadcasting correctly, and that receivers are correctly configured. You can contact Intinor for assistance with troubleshooting.
Verify the streams on Direkt link with “list streams” in the stream menu on the display or destinations under “active settings” in the web interface. Make sure the Direkt link is streaming. Multicast streams are always broadcasting. Unicast streams are sent if there is a receiver with a relevant IP number.
The Direkt link shows status information on the display that it broadcast data (in Mb). Direkt receiver will display when receiving data (in Mb).
Depending on the transport used, test the following:
UDP multicast
Make sure the Direkt link is streaming. Multicast streams should always be broad­casted. Try to switch to test picture.
Make sure the receiver is listening on the right multicast address and port.
If the receiver fails to receive the stream, test switching to UDP unicast towards the relevant receiver, and set the receiver to play UDP unicast.
UDP unicast and stream TCP
Make sure Direkt link is broadcasting to the IP number of the receiver. If the receiver is behind a firewall, make sure the Direkt link is broadcasting to the receiver’s external IP number and that the firewall is configured in a correct manner (see chapter 8).
TCP on request
Make sure that “TCP for streaming” is active in the web interface or on the display on the Direkt link.
Make sure the receiver is set on TCP (download) with Direkt link’s IP number, and the TCP port Direkt link is listening on. If Direkt link is behind a firewall make sure the firewall broadcasts TCP, with the select port, to Direkt link (see chapter 8).

9.4 Amino STB
If Aminobox is used as a receiver, it is advisable to start troubleshooting by restarting the unit. Pull out the power cable and put it in again.
Make sure the Amino logotype is displayed on the TV when starting up. If this is not the case, troubleshoot the connection between the Aminobox and the TV.
9.5 Testing the streams using a laptop
If one does not have access to a Direkt receiver or a Direkt router, it is possible to test the streams with a laptop or stationary PC located on the same network as the Direkt link. This is done with the application VLC as described in section 7.3.
9.6 Disturbances on video and audio
If a signal reaches the receiver but disturbances in video or audio is present, it is possible to make corrections according to chapter 6.8. It is also advisable to make sure that all network cables are of good quality and not too long.
If one is broadcasting over the Internet, the distance between broadcaster and receiver can be too far. Intinor can aid in mea­suring and evaluating the connection, and eventually help re­route the video stream on a different connection. Please contact Intinor for more information.

Preparations
When using a video link over a network, problems can arise, primary concerning firewalls or networks. It is wise to prepare the broadcasting in due time.
Make sure internal support, or Intinor’s support, is available when tests and live broadcasting are implemented.
If linking is performed from a location where the broadcasting has worked before, start testing no less than one hour before live broadcasting.
If linking is performed from a new location, start testing at least 24 hours before live broadcasting.
Connection and link test
The link test is preferably performed without camera - use the test picture from Direkt link.
It is preferable to connect the Direkt link in the following sequence:
1. Connect network cable if local network is available
2. Connect power
3. Connect video and audio to Direkt link, or turn on the test picture:
(a) Push OK on the display to get to the main menu. (b) Use the arrows to browse down to the menu selection “activate test pic.” and
push OK. Push OK again to confirm the selection.
4. Wait for approximately 30 seconds.
The test picture is turned off in the same way as described above, or restarting Direkt link.
If Direkt link is pre-configured it should work now. On the status display, the name, number of active streams, and current bitrate for the active profile is shown.
Select profile
To load a profile for the location, follow the sequence below:
1. Push OK on the display to get to the main menu.
2. Use down arrow to the menu option “profiles” and push OK.
3. Use down arrow to the menu option “select profile” and press OK.
4. Use down arrow to the desired profile and press OK. Press OK again to confirm the selection.
Now, Direkt link is using the configurations and streams from the selected profile.
