Introduction
The Atlona OmniStream™ 121 (AT-OMNI-121) is a networked AV decoder for one HDMI source up to 4K/UHD,
plus embedded audio and RS-232 control. The Atlona OmniStream™ 122 (AT-OMNI-122) adds a second channel
of encoding for two HDMI sources up to 4K/UHD and RS-232 control and can deliver duplicate AV streams to
two networks for full system redundancy in mission-critical applications. OmniStream features SMPTE VC-2
compression for critical-quality video applications, with extremely low, sub-frame latency from encode to decode.
It also includes selectable AES-128 encryption and SMPTE 2022-5 Forward Error Correction (FEC) for robust AV
distribution spanning multiple networks. Both OmniStream decoders are housed in compact enclosures that easily
t into a half RU space. They can be powered over the network through Power over Ethernet (PoE) or optionally from
local AC power.
OmniStream was engineered from the ground up at Atlona to deliver the performance and dependability of traditional
AV distribution, with the virtually unlimited scalability and cost eciency of integrating over data networks. It
addresses the many challenges AV and IT integrators encounter with implementing networked AV systems, while
delivering immediate and long-term ROI to end users in enterprises and other organizations.

Conguration
Discovery using AMS
It is recommended that the Atlona Management System (AMS) be used to congure and control OmniStream
devices. AMS uses multicast Domain Name Server (mDNS) to automatically congure each decoder on the network.
AMS is free and can be downloaded from https://www.atlona.com/ams.
By default, the decoders are set to DHCP mode, allowing a DHCP server (if present) to assign the 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. Note that AMS will only be able to discover decoders if they are on the same VLAN.
Accessing Decoders in AMS
1. Launch a web browser and enter the IP address of AMS, in the address bar.
2. Enter the required login credentials.
3. Click the Login button.
4. The AMS Dashboard will be displayed.
5. Click the icon, in the upper-left corner of the AMS Dashboard.

Conguration
6. Click Devices from the y-out menu.
7. Click the Unassigned option.
All available decoders will be displayed under the Unassigned category. When a decoder is unassigned, it
means that it has not been assigned to a site, building, and/or room. Refer to the AMS User Manual for more
information on these topics.
If a DHCP server is not found within 60 seconds, the decoder will be placed in Auto IP mode and assigned an
IP address within the range of 169.254.xxx.xxx. If this occurs, congure 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 the User
Manual for more information on conguring a decoder in Auto IP mode.
If no OmniStream decoders are found, then verify the following:
• The computer that is running AMS must be on the same network as the OmniStream device.
• Remove any network restrictions that may be in place. In order for mDNS to function properly, there must
not be restrictions applied to the network.

Conguration
Conguring a Static IP Address
The following section is only required to set the decoder, currently in Auto IP mode, to a static IP address. If a DHCP
server is not found within 60 seconds, decoders 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 decoder in order
for AMS to locate it on the network.
1. Make sure that the decoder 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 decoder to a PoE-capable switch. If using the
AT-OMNI-122, the Ethernet cable can be connected to either ETHERNET 1 or ETHERNET 2.
2. Connect an Ethernet cable from the PC, directly to one of the Ethernet ports on the decoder. Make sure that the
computer being used has AMS installed.
3. Congure the PC to a static IP address that is on the same subnet as the decoder.
4. Login to AMS. Refer to Accessing Decoders in AMS (page 19) if necessary.
IMPORTANT: Before continuing, 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.
5. Locate the decoder under the Unassigned section within AMS.
6. Click on the device.
7. Under AMS, click the NETWORK tab.
8. Click the DHCP Mode drop-down list and select Static.
9. Enter the required network information for the decoder in the IP Address, Subnet, and Gateway elds.
10. Click the Save button in the bottom-right corner, to apply the changes.
11. Disconnect the decoder from the PC and connect it to the network.
12. The decoder is now ready for use.

Basic Operation
Unicast Mode
The term unicast is used to describe a conguration where information is sent from an encoder to a single decoder.
Although it is common to have multiple encoder and decoder units within a system, it may also be desirable to
restrict a single encoder to communicate with one decoder. In unicast mode, OmniStream encoders and decoders
function similar to an n x 1 switcher. Changing the destination IP address at the encoder, will direct the stream to be
received by a dierent decoder.
The illustration below shows three encoders and three decoders on a network, operating in unicast mode. The red
lines indicate the data paths from each encoder to a separate (single) decoder.
NOTE: By default, both encoders and decoders are shipped in multicast mode.

Multicast Mode
The term multicast is used to describe a conguration where information is sent from one or more points to a set of
other points. For example, a single encoder can transmit data to multiple decoders. In addition, if multiple encoders
are used, each encoder can stream data to any decoder that is not already receiving data from an encoder.
In multicast mode, OmniStream encoders and decoders function similar to a matrix switcher.
The illustration below shows three encoders and three decoders on a network, operating in multicast mode, where
multiple decoders are subscribed to a single encoder. The red lines indicate the data paths from an encoder
(192.168.11.117) to multiple decoders.
NOTE: By default, both encoders and decoders are shipped in multicast mode.
