Description
The Intinor Direkt router receives video and audio from Direkt link and other Direkt router
via computer networks, monitors and re-sends to one or multiple destinations. Direkt router
2000IP with options can also transcode the video streams to other formats. The live-
broadcasted material can be received by different receivers for live-editing or distribution to
TV viewers.
Intinor Direkt router 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 router 2000IP
The Direkt router 2000IP is a robust construction with few moving parts. Intinor provides
support, can monitor and remote control links and help to ease network trouble shooting.
Similar to all Intinor products, the Direkt router 2000IP 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.

1.1 Functions
The following functions are standard on Direkt router 2000IP:
 Can receive video streams (MPEG2 and H.264) from a number of different types of
senders
 With access control, administrator can allow input streams only from specific senders
 multiple output streams TCP (error correction with buffring)
 flera utstr¨ommar UDP, unicast och/eller multicast
 RTP+FEC - error correction with low latency
 Network failover - if Direkt router can not transmit using the first network interface,
it automatically switches to the second etc.
 Network bonding - video streams can be transmitted over multiple networks for in-
creased video quality and robustness
 Easy to configure via display and keypad
 Can be controlled via web interface over network
 Can be supervised, trouble shooted and remote controlled via ISS — Intinors system
for statistics and supervision
 Backup settings can be handled via the web interface or ISS
 Software upgrade can be handled via the web interface, ISS or USB memory
 Peak Programme Meter (PPM) for easy calibration of audio level
 Settings can be stored in profiles for different broadcast locations or destinations
 Can record to files, in the video format it receives
 Recorded files can be fetched via the web interface
 Can share Internet access to devices connected to the second network port (IP2)
1.2 Customizations
Direkt router can be cusomized using options. See Intinor home page or contact a sales
person at Intinor.

Technical overview
Intinor Direkt router 2000IP receives video, compressed using MPEG-2 or H.264, from com-
puter networks and re-sends via IP net to one or multiple destinations. 2000IP handles six
concurrent input streams - channels.
Figure 2.1: technical overview
2.1 Input
The Direkt routers input is a RJ45-connector (TP) Ethernet 10/100/1000. The input is
called “IP1”.
2.2 Transport in and out
Direkt router 2000IP received and re-sends MPEG transport streams over IP either using
UDP, RTP, RTP+FEC, UDP bonding or TCP.
Transport methods are described more detailed in chapter 3.2.
The Direkt router can be configured to listen for multiple transport methods simultaneously.

2.3 Output
Direkt router’s output is a RJ45-connector (TP) Ethernet 10/100/1000. The primary output
is “IP1”, but also “IP2” can be used as output.

Usage
3.1 User interfaces
Intinor Direkt router has three user interfaces:
a) The web interface gives access to all configuration options. The web interface is de-
scribed in chapter 3.12
b) The display and keypad on the Direkt router gives access to basic configurations. The
display can be used when the web interface is unavailable. See chapter 3.11
c) ISS is used for supervision, status, remote control and trouble shooting. See chapter
3.4
(a) Web interface (b) PPM, display and keypad (c) ISS for supervision and trou-
ble shooting

3.2 Transport methods
Direkt router supports different technologies for both transport in from Direkt links and
transport over IP networks to one or several receivers.
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.

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 appli-
cations and internal distribution on a LAN).
3.2.2 UDP unicast
If there is no support for multicast, then unicast is to be used to stream to each receiver.
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.
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 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.
3.2.4 RTP and RTP + FEC
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 transmis-
sion. 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.
