1.2 What is Targa-2 Receiver?
Targa-Receiver is a compact video and audio decoder which is designed for
TV broadcast applications. It is attached to LAN Networks using its Ethernet
port.
Targa-Receiver can decode SD and HD H264 encoded elementary video
streams and AAC audio streams. It features an integrated Deinterlacer and
Scaler, which automatically upscales SD content to HD resolutions.
Targa-Receiver supports professional Video Interfaces like HD-SDI and HDMI
with integrated audio output. Additionally it includes an analog audio output.
When used in combination with a Targa-Transmitter, the Targa Receiver has
several unique functions:
•VPN-Tunnel: The Transmitter can connect to the Receiver over an
encrypted VPN-Tunnel for data security.
•Audio Return Channel: The Receiver can record from analog audio
input and stream it to the Transmitter. This can i.e. be used by
producers to give directions to the camera operators.
•Transparent CAN-Tunnel: Transmitter and Receiver can establish a
TCP-based CAN-Tunnel over which CAN-packets can be relayed. This
can i.e. be used to exchange data between a vehicle and an industrial
controller.
•Latency measurement: The Receiver can measure the capture to
display latency of the video stream.

and settings to get your Targa device up and running. For an in depth
explanation off all features see chapter 3.
2.1 Connecting Targa
Targa can be connected to a display using the HDMI or HD-SDI output. Analog
audio can be connected over 3.5mm audio in and out jacks.
To receive a video stream connect Targa via the ETH port using an Ethernet
cable and proceed with “Power-on”.
2.2 Power-on from DC Adapter
Connect the DC Adapter to the power connector, then switch on the power
switch.
2.3 Power-off in DC Adapter Mode
Simply switch of the power switch.
2.4 Configuration of the Transmitter
The decoder will need to be configured once using the Ethernet cable.
The default static decoder IP address is: 192.168.1.1
2.4.1 Adjusting the Computer’s IP Address
Configuration is made on the encoder’s web interface. For access, your
computer’s IP address for the Ethernet network connection must be inside
the 192.168.1.XXX subnet (e.g. 192.168.1.2)
To set the IP address, open your start menu and search for “Network and
Sharing Center”, open it and then click on your current connection (e.g.
“Local Area Connection”). In the next window click “Properties” and then
double-click “Internet Protocol Version 4 (TCP/IPv4)”. Chose “Use the
following IP address” and enter the following numbers:

2.5 Accessing the Web Interface
Open the web interface of the Targa Transmitter by typing the following URL
in the address bar of your browser: http://192.168.1.1
Now, the following login page should be displayed:
If no password is set (which is the default with factory settings), just click on
the Login button without entering a password. This brings you to the Status
page:
A password can be set up on the System  Administration tab. Go to chapter
3.2.2 for more information.

Quickstart
12
The web interface can be used to configure all functions of the Targa
Receiver. It is navigated using the main tabs which are displayed below the
Dream Chip logo and version string. Each tab can have multiple sub tabs with
further settings and information.
On many tabs, the following buttons can be found:
Button
Description
Deletes the related settings (e.g. a streaming
destination). Make sure you don’t need the settings
anymore as you cannot undo this step.
Adds e.g. a streaming destination without changing or
deleting another one.
Resets the related settings to default settings.
Saves the related settings, but does not apply them
Saves and applies the related settings
After making changes to a tab please click on the “Save & Apply” button in
the lower right corner of the tab page. Please note that execution of the new
settings might take a while (especially if settings of the encoder are changed),
because the Targa device has to be reconfigured. The web interface will
inform you with a notification in the top left corner of the tab when the
settings have been successfully applied.

2.6 Network Settings
Network settings can be configured in the Network tab:
Here, you can see three network interfaces:
•LAN interface referring to the ETH Port
•VPN interface referring to a virtual network that is used to secure
data transmission (see chapter 3.3.2 for more details)
•By default the WAN interface is not used
The Targa user interface is based on a Linux distribution specifically designed
for IP router applications. As such an experienced user may setup network
settings, firewall and routing rules to his liking. The following chapters
describe the basic setup which will be sufficient for most use cases.
2.6.1 Configuration of Ethernet Settings
To change the local IP address of the transmitter, click on the Edit button of
the LAN interface to configure the IPv4 address (default 192.168.1.1) and
IPv4 netmask (default 255.255.255.0).
If you want to directly stream video and audio to a Targa Receiver from the
internet (e.g. using a Targa Transmitter), make sure that your device is
connected to a public network with internet access. You will then have to

Quickstart
14
enter IP address, netmask and standard gateways according to your internet
service provider. Also make sure that all ports used for sending / receiving
data are opened in any involved firewalls of your network.
Having entered the changes, don’t forget to click on “Save & Apply” in the
respective tab to save your changes.

Quickstart
15
2.7 Decoder Configuration
Connect your display to the transmitter via the HDMI or HD-SDI output. Then
open the Targa Decoder tab and go to the Video/Audio sub tab.
2.7.1 Video Settings
The receiver can decode HD video streams with a resolution of 1280x720
(HD) or 1920x1080 (Full-HD) pixels, SD streams can have resolution of either
448x256, 672x384 or 1024x576 pixels. Set the “Video Mode” to the
resolution of the incoming video stream.
The receiver will scale the incoming video to the selected “Display Timing”.
Please select a timing that matches the framerate of the incoming video
stream.
The video port must match the port of the transmitter.
2.7.2 Audio Settings
You can enable audio playback, which will output the received audio stream
on all three sinks (HDMI, SDI, analog output). Make sure the audio port
matches the transmitter settings.
If you want to transmit an audio return channel from the receiver to the
transmitter, enable the “Audio Return Channel” feature. Only the analog
audio input can be used as source. If the analog audio source is a
microphone, enable the microphone bias by changing the “Micro Mode” (this
will power the microphone with 2 or 2.5V). If you attach an active audio
source (like a DVD player or a smartphone), leave the bias disabled. You can
then adjust the “Capture Volume”, please note that high capture volume
values will lead to high static noise in the recorded signal.
To be able to transmit audio data to a Targa Transmitter which is connected
via LTE you will need to use the VPN feature, because the Receiver cannot
directly reach the IP address of the Transmitter. For further details see
chapter 3.3.2 and 3.5.2.

Quickstart
16
The “Audio Sample Rate” can usually be left at 48 kHz, if your application
requires it, you may change it to 44.1 kHz.
2.7.3 General Settings
Usually you will not need to change the settings listed under “General
Decoder Settings”, for more details on these advanced settings see chapter
3.5.2.
Save your changes by clicking on “Save & Apply”.
