Configuration
Discovery using AMS
To determine the IP address of the encoder, use AMS. AMS is available only for the Windows® Operating System.
If necessary, mDNS/Bonjour can also be used to discover the IP address of the encoder.
By default, OmniStream products are set to DHCP mode, allowing a DHCP server (if present) to assign each encoder/decoder an IP address. Once an IP address has been assigned, the Atlona Management System (AMS) can be used to manage the product on the network. AMS will only be able to discover encoders if they are on the same
VLAN.
If a DHCP server is not found within 60 seconds, the encoder will be placed in Auto IP mode and assigned an
IP address within the range of
169.254.xxx.xxx. If this occurs, configure the network interface of the computer that is running AMS, located on the same subnet (
169.254.xxx.xxx, subnet mask 255.255.0.0). Refer to
Configuring a Static IP Address (page 15)
for more information on configuring an encoder in Auto IP mode.
1. Launch the Atlona Management System from the Windows Desktop or from the Start Menu.
2. After the AMS server starts, click the OK button to dismiss the dialog.
3. Launch a web browser and type localhost:8080 in the address bar, as shown below.
4. Enter the login information on the AMS web page, then click the Login button. Note that the password is masked when typed.
Login: admin
Password: admin123
AT-OMNI-111 / AT-OMNI-112 13
Configuration
5. Under the Domain View, locate the IP address for the encoder. Single-channel encoders will be labeled as
OMNI-111. Dual-channel encoders will be labeled as OMNI-112.
If no OmniStream devices are found, then make sure that both the encoder and the computer that is running
AMS are on the same subnet.
IMPORTANT: OmniStream uses mDNS as the discovery mechanism. In order for mDNS to function properly, there must not be restrictions applied to the network. VPN can be used to connect to a computer that is running AMS, on the same network. However, VPN cannot be used when AMS is running on the local machine.
6. If, after verifying the above restrictions, no OmniStream devices are listed under the Domain View, then follow the procedure below.
a. Make sure that both the encoder and the computer that is running AMS are on the same subnet.
b. Remove any network restrictions that may be in place.
c. In AMS, click Start > Add Device > Auto > Stop mDNS Discovery. This feature is enabled, by default. d. After a few moments, the following message box will be displayed. Click the OK button to dismiss the message box.
AT-OMNI-111 / AT-OMNI-112 14
Configuration e. Restart the mDNS listener by clicking Start > Add Device > Auto > Start mDNS Discovery.
f. After the mDNS listener is enabled, click the OK button to dismiss the message box.
g. The list of OmniStream devices should now be listed under the Domain View pane.
Configuring a Static IP Address
The following section is only required to set an encoder, currently in Auto IP mode, to a static IP address. If a DHCP server is not found within 60 seconds, encoders are automatically placed in Auto IP mode and will be assigned an IP address within the range
169.254.xxx.xxx. If this occurs, a static IP address can be assigned to the encoder in order for AMS to locate it on the network.
1. Make sure that the encoder is powered. Power will need to be supplied either by the external 48V power supply
(not included) or by connecting an Ethernet cable from the encoder to a PoE-capable switch. If using the
AT-OMNI-112, the Ethernet cable can be connected to either Eth 1 or Eth 2.
2. Connect an Ethernet cable from the PC, directly to one of the Ethernet ports on the encoder. Make sure that the computer being used has AMS installed.
3. Click Start > Settings > Control Panel > Network and Sharing Center.
4. Click Change adapter settings.
5. Right-click on the adapter that is used to establish a wired connection to the network, and select Properties from the context menu.
6. Under the Ethernet Properties dialog box, select Internet Protocol Version 4 and then click the Properties button.
7. Click the Use the following IP address radio button.
IMPORTANT: Before contrinuing, write down the current IP settings in order to restore them, later.
If Obtain an IP address automatically and Obtain DNS server automatically are selected, then this step is not required.
8. Enter the desired static IP address or the IP address provided by the network administrator.
If the PC does not require Internet access or if a statically-assigned IP address is being used, then an IP address of
169.254.xxx.xxx can be entered.
9. Set the subnet mask to
255.255.0.0.
10. Click the OK button then close all Control Panel windows.
11. Launch AMS.
12. Locate the encoder under the Domain View of AMS. Single-channel encoders will be labeled as OMNI-111.
Dual-channel encoders will be labeled as OMNI-112.
AT-OMNI-111 / AT-OMNI-112 15

Session Configuration
Once the inputs have been assigned to the desired source, the next step is to configure each session. A session is primarily a multicast IP address that is assigned to an AV stream. When each stream is configured for bit rates less than 450 Mbps (only recommended for 1080p and lower resolutions), a single Ethernet cable can transport two sessions. The dual-channel encoder supports up to four sessions to enable redundancy for dual 1080p-use cases.
The single-channel encoder supports a maximum of two sessions to enable redundancy for single 1080p-use cases.
1. Select the desired encoder under the Domain View pane, within AMS.
2. Click the Session tab. The Session 1 tab will be active, by default.
3. Under the Session 1 block, select the desired interface from the Interface drop-down list.

Physical Interfaces & Cross Connections
The following example provides a better understanding of how physical interfaces and cross connections work together.
Figure 3 shows a very simple setup: two sources are connected to a dual-channel encoder. Both Ethernet cables are connected from the encoder to the Local Area Network (LAN). Another set of Ethernet cables connects to a dualchannel decoder, somewhere on the same network. The Ethernet cables are the physical interfaces - that is, they provide a physical link - that allows the AV stream to be transported, over the network, from an encoder to a decoder endpoint.

In Figure 3, the gray lines indicate that no signal is being sent from the encoder, over the Ethernet cables. Before a stream can be sent across the network, a cross connection must exist between two physical interfaces. Cross
connections are created under the Virtual Matrix tab, in AMS. Figure 4a shows a cross connection that joins
Ethernet 1 on the encoder to Ethernet 1 on the decoder. Figure 4b shows the result of the cross connection (green line) in the setup. Note that the second Ethernet line is still gray, indicating that the cross connection for this physical interface has not yet been created. Once a cross connection is created, the decoding process starts automatically.

• FEC can only work if a single packets from each row/column are missing. Multiple packets missing from each row/column will cause FEC to fail.
• Due to the above, a smaller matrix is more robust, as there is a better chance of errors not occurring in the same row/column.
• FEC has a bitrate overhead that is inversely proportional to the matrix size: the bigger the matrix, the less bitrate overhead is generated.
• FEC has a latency overhead that is directly proportional to the matrix size: the bigger the matrix, the more latency is introduced.
» As of v1.0.0, OmniStream does not explicitly synchronize audio and video. Therefore, FEC configuration can have a noticeable impact on lip sync. The tables below should be used to keep the audio/video lip sync as tight as possible.
• FEC latency overhead is also inversely proportional to bitrate: the higher the bitrate, the less FEC latency is introduced.
»
For applications where lip sync is very critical, using a higher audio sampling rate, and thus a higher audio bitrate, can result in more accurate lip sync.
FEC and Video Bitrate
• The bitrate configured on the video encoder includes FEC overhead and will automatically adjust itself depending on the bitrate needed for FEC.
• FEC overhead can be calculated using the following formulas:
Configured bit rate
Video rate =
FEC rate = Configured bit rate - Video rate

FEC, Latency, and Lip Sync
• In order for FEC to work, the matrix must be filled in order to calculate the FEC packets. This introduces some additional latency. Due to high bitrates, this is not noticeable for video, but can be very significant for audio.
Therefore, Atlona recommends either leaving FEC disabled for audio or using a very small matrix.
• Latency calculations are complex. The tables below provide some common working benchmarks. In order to minimize lip sync issues, try to match the additional latencies for video and audio as closely as possible.

• It is recommended to keep lip sync within ±1 frame of video to prevent any noticeable syncing issues.
• Examples of good choices to minimize lip sync issues are:
» Video configured for 450 Mbps, FEC 10x10; Audio is 2 channel PCM, 192 kHz, FEC 1x4: 6.40 ms – 7.81 ms
= -1.41 ms
» Video configured for 900 Mbps, FEC 10x10; Audio is 2 channel PCM, 48 kHz, FEC disabled: 6.40 ms – 0 ms
= 6.40 ms
