2Introduction
2.1 Principles of Operation
Somewhere in the world is a location that transmits your signal, along with many others, up to a
terrestrial broadcast transmission tower that sends those signals to your location, and many others.
Your ATSC antenna receives these signals and sends the to the A75 ATSC receiver. The A75 sifts
through all the signals sent by the broadcast tower looking for your signal (an ATSC stream) and
forwards to your computer the portion containing the data you want. The Ethernet card on your
computer can further filter that data and pass it to other programs on your PC.
The A75 Management Console is used to configure addresses, specify channel parameters, select
ATSC information streams by Program IDentification number (PID) and map audio/video PIDs to
multicast address(es). Once configured, the A75 will retain its settings and continue to forward data
transmitted to you by your service provider even after restarting the A75 or your PC.
The A75 Receiver does not require a computer to continue operation. Once the options have been
set you will have no need to change them.

NOTE: IGMP is an Internet standard that is used to control multicast traffic on the LAN
based on the client’s interest in the stream. For proper operation, all components of
your network should support IGMP
3.2 What Information do I Need –Basic Configuration?
1. The IP Address to be assigned to your Novra A75 Receiver
a. Example: 192.168.170.125
2. The IP Address Subnet Mask
3. The IP address of the Default Gateway for the receiver.
4. Is the receiver supposed to filter multicast traffic using IGMP?
5. The ATSC Channel number
NOTE: -This information is needed in order for the receiver to function. It is
recommended that all the information be collected before attempting to install the
service.

Version: 1.02Confidential and Proprietary 9of 32
NOTE: -You MUST be logged onto the system as Administrator, for the
network settings function to work properly.
3.3 SOFTWARE Installation on Windows 2000, or XP
The A75 Console software is supplied as a single executable. Therefore, it is easy to install on
different systems. All you need to do is copy the executable to your working directory.
3.4 A75 Startup and Main Screen
1-Start the A75 Console software. Once running you will be presented with the A75 Console main
screen as shown in Figure 2 below.
2-Before starting to configure your A75, you must ensure the network settings of the device make it
accessible from the Windows management PC. The IP address of the device and the IP address of
the management station must reside on the same subnet, or there must be a route that connects both
of them through a router. For the simple case where the A75 and the management PC are
connected via an Ethernet crossover cable or through an Ethernet hub, there are two different ways
this may be accomplished. The A75 Console will automatically detect all A75’s that are presently
connected to the management PC LAN. Clicking on the Device List Icon (item [3] in Figure 2
below), will present the list of connected A75’s. This list will identify the A75(s) by MAC, IP address
and A75 type. Click on the one you wish to configure, and the status box of the Console main screen
will be updated with the A75 information.
You must now ensure that your A75 IP address and your Management PC IP address are on the
same subnet. As mentioned, this can be done in one of the two ways:
1. In the console status box, the IP address of your A75 will be displayed. Note the A75 IP
address and change the IP address of your management PC Network Interface Card (NIC)
(the one that’s connected to the A75) to be on the same subnet as the A75. The PC NIC IP
address may be changed using My Network Places in Windows. If unsure, please refer to
your Windows user manual to perform this operation, OR
2. Even though your A75 and your management PC are not on the same subnet, the A75
console has been designed to be able to change the network settings of the A75. Therefore,
in the A75 Console, click Configure and then Network. This will bring up the A75 network
NOTE:
-
You MUST be logged onto the system as Administrator.
NOTE: -Your screen resolution MUST be at least 800 x 600 and at least
"16 bit color" to function properly.

Version: 1.02Confidential and Proprietary 10 of 32
NOTE: -If the A75 and the management PC are not on the same subnet,
you will be able to change the network settings of the A75, but will not be
able to configure the Content or Channel settings.
settings, which include the receiver IP address and subnet mask, and gateway IP address.
Change these address parameters to match you management PC LAN subnet. For example,
if your PC NIC is set to 192.168.5.1, you may wish to change your A75 IP address to
192.168.5.2.
Figure 2 -A75 Console Main Screen
The A75 Console main screen enables the operator to select, configure and view status of the
selected A75. Three main buttons are provided enabling the operator to:

4.1.1 Network Button
The Ethernet network settings of the A75 may be modified by selecting the Network Button and changing
the appropriate fields (as shown in the figure below).

Version: 1.02Confidential and Proprietary 13 of 32
NOTE: -Proper operation of IGMP protocol requires that all devices used in the
network support IGMP protocol.
Figure 4: Network Configuration Dialog Box
1. Receiver Address -This is the IP address to be assigned to the receiver
2. Subnet Mask -This is the subnet mask that the receiver should use to determine whether an IP
address belongs to the same network or not.
3. Default Gateway -This is the IP address of the router that the receiver should use whenever
it wants to send traffic to a non-local address (IP address that does not belong to the local
subnet).
4. Use IGMP for filtering Multicast Traffic -This check box allows the user to turn IGMP
filtering on or off. IGMP controls which multicast streams will be forwarded on the LAN based on
the number of clients listening to that stream.
5. Send Status To -This is the IP address used to send Unicast status copies for remote
monitoring purposes

Version: 1.02Confidential and Proprietary 14 of 32
NOTE: -The Device status can be sent to a remote management station by
configuring the status destination IP. However these settings don’t affect the
broadcast status messages. To turn off the unicast status, set the destination IP
address to 255.255.255.255.
6. Selecting the Check icon will send the network changes to the A75 receiver
7. Selecting the X icon cancels the changes and exits back to the main screen

PID’s and therefore the Video PID box is not displayed in the Content screen
7. Selecting the PID Delete All icon will empty the PID list
8. Selecting the Check icon will send the PID changes to the A75 receiver
9. Selecting the X icon cancels the changes and exits back to the main screen
4.1.3.1 Adding Video PIDs
Any of the PID’s added in the section above (Section 4.1.3) may be configured and received as an ATSC
elementary stream PID (versus an MPE PID) and passed directly to an IP address (multicast, unicast or
broadcast) on the A75 LAN. This feature enables the operator to pass television program PIDs (including
audio, video and MPEG Service Information (SI) PID’s)on the LANfor viewing. Section below provides a
detailed description of how to configure the A75 to receive TV signals and how to setup an incoming PID as a
video PID.
To start with, you simply select the PID and check the Video PID box. This will bring up the Video PID
Screen as shown below.
