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.

1.1 Functions
The following functions are standard on Direkt receiver SDI:
 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
 Easy to configure via display and keypad
 Can be controlled via web interface over network
 Backup settings and software upgrade can be handled via the web interface or ISS
 Peak Programme Meter (PPM) for easy calibration of sound level
 Can be supervised and trouble shooted via ISS — Intinors system for statistics and
supervision
 Support for error correction (TCP with buffering)
 Test picture can be generated and customised
 Shows test picture if input signal is missing

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.

Usage
3.1 User interfaces
Intinor Direkt receiver has three user interfaces:
a) The web interface gives access to all configuration options. The web interface is de-
scribed in chapter 3.8
b) The display and keypad on the Direkt receiver gives access to basic configurations.
The display can be used when the web interface is unavailable. See chapter 3.7
c) ISS is used for supervision, status and trouble shooting. See chapter 3.3
(a) Web interface (b) PPM, display and keypad (c) ISS for supervision and trou-
ble shooting

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.

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.
