OmniStream products are similar in principle to matrix switch endpoints: A/V signals are sent from one point
(transmitter) to another point (receiver) over category cable. However, OmniStream stands apart from matrix
switchers, in that it is an IP-based solution, allowing this data to be sent over a standard IP network. In addition,
these endpoints are referred to as encoders and decoders. Encoders act as “transmitters” and decoders act as
“receivers”.

Encoder IP Address: 192.168.1.27
IP Address Assignment
Figure 1.1 below, shows an encoder and a decoder, connected through a network switch. As with all network
devices, both the encoder and decoder must have unique IP addresses. OmniStream encoders and decoders are
DHCP-enabled, by default. This means that when the encoder/decoder is connected to the network, and a DHCP
server is available, the encoder/decoder will automatically be assigned an IP address. If no DHCP server is available,
then the unit will use a self-assigned IP address within the range of 169.254.xxx.xxx/16. OmniStream devices
can also be assigned a static IP address, if necessary. Static IP addressing will be covered in a later section.
Figure 1.1 - An encoder and decoder on a network, with assigned IP addresses.
DEFINITIONS
Encoder – Compresses source signals before sending them out over a network environment.
Decoder – Receives and decompresses signals from an encoder and sends them to an output
device, such as a display or other sink device.
IP Address – A unique numerical label that is assigned to each device connected to a network.

Network Bandwidth and OmniStream Compression
When sending video and audio over a network, the available bandwidth needs to be managed. Gigabit Ethernet
switches are very common and can take advantage of installed Category 5e cable. 10-Gigabit Ethernet switches
are available, but are more expensive per port and require Category 6A cable or better. The chart below shows
uncompressed data rates for common resolutions. These data rates exceed the available bandwidth of Gigabit
Ethernet, but using the compression technology in OmniStream, this video can be streamed over cost-eective
Gigabit networks.
Resolution Data Rate*
1920 x 1080p 30 Hz 2.2 Gbps
1920 x 1080p 60 Hz 4.5 Gbps
3840 x 2160p 30 Hz 8.9 Gbps
3840 x 2160p 60 Hz 17.8 Gbps
OmniStream compresses the source data at the encoder, before it is sent out over the network. This process is
known as encoding. OmniStream uses VCx and VC-2 compression, which are intermediate compression schemes
and is much more desirable than using a interframe compression scheme, such as H.264 or H.265. Interframe
codecs are typically used by cable or internet providers and use very aggressive bit rates (low bandwidth) with high
latency (delay), which results in lag. VCx and VC-2 provide both high quality (high bit rates) and very low-latency for
a much more desirable viewing experience.
* Data rate is shown without compression.
Streams
Sessions
The term stream is used throughout this manual, to describe the dierent types of signals that are transmitted over a
network. For example, if a blu-ray player is connected to an encoder, both video and audio are sent to the encoder
over an HDMI cable. The term video stream is used to identify the video portion of a signal and audio stream
identies the audio portion of the signal.
A session is a way of organizing audio and video streams. The session identies each stream with a unique multicast
IP address and UDP port assignment. This provides an address to determine where the package of audio and video
should be sent. Figure 1.2 illustrates how a session encapsulates a video and audio stream.
Figure 1.2 - Video and audio streams contained within a session.

NOTE: Sessions are not limited to only video and audio streams. Control data, such as IR and
RS-232, as well as AES67 audio, can also be contained within a session. These topics will be
covered in a later chapter.

Introduction to OmniStream
Subscribing to a Stream
To receive information from an encoder, the decoder must subscribe to the multicast IP address and UDP port of
the stream(s). Note that the decoder does not subscribe to the session, but to the stream(s) within the session.
The process of subscribing is similar to changing the channel on a Set-Top Box. For example, in order to view the
content on channel 213, the Set-Top Box must be set to channel 213. Similarly, for a decoder to subscribe to an
encoder stream, the multicast IP address and UDP port settings on the decoder must be set to the same values as
the encoder to which it is subscribed. Note that the management IP address of a unit is dierent than its multicast IP
address.
Figure 1.4 shows two encoders and a single decoder connected to a network switch. Decoder “C” is subscribed to
encoder “A”, since the multicast IP addresses and UDP port numbers for both video and audio are set to the same
values as encoder “A”.

Accessing OmniStream Devices
The Velocity Device Manager uses multicast Domain Name Server (mDNS) to automatically discover each encoder
on the network.
By default, the OmniStream devices are set to DHCP mode, allowing a DHCP server (if present) to assign the
encoder an IP address. Once an IP address has been assigned, Velocity can be used to manage the product on the
network. Note that Velocity will only be able to discover encoders if they are on the same VLAN.
In order for Velocity to automatically assign multicast IP addresses to OmniStream devices, the destination IP
addresses for the session streams must be cleared.
Getting Started
1. Launch a web browser and enter the IP address of Velocity, in the address bar.
2. Enter the required login credentials.
3. Click the LOGIN button.
NOTE: The following steps are required only if a pre-existing multicast IP address is
assigned to each session and if automatic assignment of these multicast IP addresses, using
Velocity, is desired.

7. Click the desired OmniStream device from the Unassigned list.
8. The control interface for the device will be displayed and the device can be congured as desired.
The illustration below shows the DEVICE INFO screen for an AT-OMNI-112 encoder.
If a DHCP server is not found within 60 seconds, the encoder will be placed in Auto IP (APIPA) mode and
assigned an IP address within the range of 169.254.xxx.xxx/16. If this occurs, congure the network
interface of the computer that is running Velocity, located on the same subnet (169.254.xxx.xxx, subnet mask
255.255.0.0). Refer to Conguring a Static IP Address (page 89) for more information on conguring an
encoder in Auto IP mode.
If no OmniStream encoders are found, then verify the following:
• The computer that is running Velocity 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 any restrictions applied to the network.

Conguring Inputs
The INPUT page is used to verify that the encoder recognizes the source device. This page is also used to set the
EDID, HDCP version, and provides detailed information about the source signal. The following procedure should be
performed on both AT-OMNI-111 encoders.
1. Click INPUT in the menu bar and locate the HDMI Input 1 window group. Since a source has been connected
to the HDMI IN port, the Cable Present indicator is green. This indicates that an active source is connected to
the HDMI port.
If these indicators are red, check that each source is connected to an HDMI IN port. A red indicator may also
describe faulty HDMI cables. If the sources are connected, then try dierent HDMI cables. If the HDMI cable
integrity has been veried, then make sure that the output resolution of the source is at least 720p.
TIP: If no signal is being received on the encoder, then it’s always a good practice to check the
INPUT page on the encoder when performing additional troubleshooting.

Encoder Settings
Basic Conguration Tutorial
The INPUT page is also used to assign an input to an encoder. The Encoder window groups allow video settings,
such as the maximum bit rate, bit depth, and chroma subsampling to be set. Video thumbnails of the source device
can also be displayed on this page. The following procedure should be performed on both AT-OMNI-111 encoders.
1. Under the Encoder 1 window group, click the Input drop-down list and select HDMI Input 1.
2. Enter 750 in the Max Bit Rate eld. This means 750 Mbps. Bandwidth per port is calculated as 900 Mbps,
and on a dual-channel encoder, the combined bandwidth of both ports should not exceed 900 Mbps. So, if two
sources were connected to AT-OMNI-112 dual-channel encoder, then the Max Bit Rate eld for both Encoder 1
and Encoder 2 should not exceed a value of 450.
3. Click the Subsampling eld to set the chroma subsampling value. In this example it will be set to 4:2:2.
4. The Force YUV toggle switch can be set to on to force YUV color space. In this example, it will be disabled
(default). If enabled, the toggle switch will be green.

Basic Conguration Tutorial
Creating a Session
Before the video and audio (if any) can be sent out over the network, a session must be created on the encoder.
The session assigns each stream to a unique multicast IP address and UDP port assignment. Sessions are always
created on encoders. Refer to SESSION page (page 109) for a detailed description of all settings. The following
procedure should be performed on both AT-OMNI-111 encoders, except where noted.
1. Click SESSION in the menu bar, locate Stream 1, and click the Interface drop-down list to select the desired
interface. This can be changed to eth1 or none. For this example, Stream 1 will be transmitted over the
ETHERNET 1 port. Therefore, set this to eth1.
2. The Scrambling toggle switch is enabled by default. When enabled, this toggle will be orange. Leave this setting
enabled.
3. The Key eld is set to scrambling by default. Scrambling keys can be any combination of alphanumeric
characters and it is good practice to use them. For this tutorial, use the default key.
4. Select the encoder for the video stream. In the last section, HDMI Input 1 was assigned to Encoder 1.
Therefore, set the Video > Encoder eld to Encoder 1.
5. Click the Video > Enable Video toggle switch and make sure it is enabled for Stream 1. When enabled, the
toggle switch will be green. If set to disabled, then the encoder video stream will be disabled.
6. Enter the multicast IP address for the video stream in the Video > Destination Multicast/Unicast Address eld.
Atlona recommends using multicast IP addresses, as shown in Table 1.1 on the next page. Enter 226.0.0.1 in
the Video > Destination Multicast/Unicast Address eld for Stream 1 on Encoder #1. For Encoder #2, enter
226.0.0.2 in the Video > Destination Multicast/Unicast Address eld for Stream 1.
7. Enter the UDP port in the Video > Destination UDP port eld. Although any valid UDP port can be used, Atlona

Subscribing to an Encoder
The next step is to congure the decoder so that it is able to receive video, audio, and/or data (control) streams from
the encoder. This process is referred to as “subscribing to the encoder”.
1. Go to the decoder, click IP INPUT in the menu bar, and locate the IP Input 1 window group. Verify that the
Enable toggle switch is enabled. When enabled, the toggle switch will be green. Perform the same procedure
for the IP Input 2 window group.
2. Under the IP Input 1 window group, enter 226.0.0.1 in the Multicast Address eld. Under the IP Input 2
window group, enter 226.0.0.2 in this eld. These multicast IP address are the same addresses that were
specied under the Video > Destination Multicast/Unicast Address eld for the encoders.
3. In the Port eld, enter 1000 under both IP Input 1 and IP Input 2 window groups. These are the same port
settings that were entered under the Video > Destination UDP Port eld of the encoder.
4. Click the SAVE button, under the IP Input 1 and IP Input 2 window groups, to commit changes.

Although there is no hard and fast rule for which IP Input window groups should be used for video, audio, and/or
control, it can be helpful to visualize the IP Input window groups as columns and rows to better organize the IP data.
The following tables were used to organize the data.

Conguring the HDMI Output Stream
1. Click HDMI OUTPUT in the menu bar, locate the HDMI Output 1 window group, and verify that the
Descrambling > Enabled toggle switch is enabled. When enabled, this toggle will be green.
2. The Descrambling > Key eld is set to scrambling by default. This is the same key that is being used under
the Scrambling > Key eld on the encoder, and will allow the decoder to descramble the signal and send it out
over the HDMI output to the display. Leave this key at it’s default setting.
3. Click the HDCP > Supported Version drop-down list and select the HDCP version. 2.2 will work with most
sources. However, in this case, an older sink/monitor, which doesn’t support HDCP 2.2, is being used.
Therefore, the value is set to 1.4.
4. Click the Video > Video drop-down list and select the video source. Based on what has been congured, the
following options are available:
Video > Video
IP Input 1 - 226.0.0.1:1000 | 10.1.0.111
IP Input 2 - 226.0.0.2:1000 | 10.1.0.116
IP Input 3 - 226.0.10.1:1000 | 10.1.0.111
IP Input 4 - 226.0.10.2:1000 | 10.1.0.116
Since this is the Video eld, a video source should be selected. Referring to Table 1.3, on the previous page,
IP Input 1 - 226.0.0.1:1000 | 10.1.0.111 and IP Input 2 - 226.0.0.2:1000 | 10.1.0.116
are video data, from two dierent encoders. For this example, this eld will be set to IP Input 1 -
226.0.0.1:1000 | 10.1.0.111.

Anchor Point
General Overview
DEFINITIONS:
Subframe - The stream multicast IP address for the video.
Anchor point - A xed point on a subframe. The anchor point can be set to top-left, top-right,
bottom-left, bottom-right, or center. Each anchor point is dened by an x and y coordinate.
Z-order - Determines whether a frame appears in-front-of or behind another subframe.
Subframes with a larger z-order value will appear in front of a subframe with a smaller z-order
value.
NOTE: Multiview cannot be used in conjunction with fast switching and/or with video walls.
The images below shows the dierent anchor point options on a particular subframe. For any given subframe, only
one of these will be selected as the anchor point.
If the incoming stream changes resolution, the size of the subframe will change on the screen if scaling is not
congured on the encoder. While the decoder HDMI output can be scaled, there is no per-subframe scaling. This is
because the incoming stream is not scaled in the decoder. To illustrate this, consider the following examples.

Anchor Points
Anchor points will be placed on the canvas at the x and y coordinates of that canvas. If the decoder output is not
scaled, then this will correspond to the actual coordinates on the display. If the decoder output is scaled, then the
Anchor point will be rendered on the canvas at the specied coordinates, and then the entire output image will be
scaled.
Because of the way the VCx codec works, anchor points must be placed on coordinates where the x value is
divisible by 32 and the y value is divisible by 8. If a coordinate is entered that does not meet this requirement, then
the decoder will automatically snap the coordinates and notify the user of the change.
Top Left
Bottom Left
Bottom Right
Center
Top Right
In this case, when the stream changes to 1280 x 720, the subframe will grow in size and be cropped by the display,
because the top left anchor point has not change position
If the incoming stream changes resolution to 1280x720, then the subframe will grow in size, but it will still t on-
screen, because its bottom right Anchor point has not changed position.

Dual-streaming has been successfully congured on both encoders. This provides a total of four streams which are
listed in the tables, below, for reference.
The next step is to congure each decoder to subscribe to these streams. Although, in the tutorial diagram, each
decoder is subscribed to no more than two streams, we will congure all three decoders to access all four streams.
This will allow us to change the output on the displays, if desired.

Positioning Subframes
Each subframe in a multiview can be repositioned on the screen based on its anchor point. The anchor point (0,0)
represents the top left corner of the multivew canvas. For example, in the picture-in-picture example that was
created on Decoder #1, the settings for each subframe are as follows:
The background color can be seen if any portion of the canvas is not covered by a subframe. Refer to the illustration
below. For example, in this PiP conguration, subframe 1 contains no image. Instead of a blank background,
the background color is displayed. The default background color is black: (RGB) 0,0,0.
To move ip_input2 (camera source) to the left, decrease the x value.
1. Click the Multiview menu.
2. Locate the Subframe sections and adjust the x and y values as desired, based on the anchor point.
3. Click the SAVE button to commit changes.

Changing the Z-Order
The ordering of overlapping subframes in two-dimensional space is referred to as the z-order. In the illustration
below, the red window is set to priority 4 and will be displayed on top of all other subframes. Assigning a subframe
to z-order 1 (the blue window) will move the subframe behind the other subframes. The larger the z-order value, the
higher the subframe priority will be. Subframes cannot share the same z-order value.
Note that subframes do not support transparency. This is only used in the diagram to illustrate how overlapping
subframes can be placed behind or in front or one another.
1. Click MULTIVIEW in the menu bar.
2. Click the Available Multiview drop-down list and select the desired multiview to be modied.
3. Click the name of the desired subframe to modify. Depending on the layout type, the name of each subframe will

Conguring Audio Output
In addition to passing audio directly from the encoder to the decoder, both the AT-OMNI-121 and AT-OMNI-122
provide two additional audio options
• HDMI audio can be de-embedded and output to two-channel analog audio.
• Two-channel analog audio can be embedded and output over HDMI.
This section covers both methods. If using a single-channel decoder, only a single AUDIO IN and AUDIO OUT port
will be available.
De-embedding audio will extract the HDMI audio and automatically downmix to two-channel analog audio, using the
included captive-screw connectors.
De-embedding Audio
1. Connect the power supply to the DC 48V connector on the decoder.
2. Connect the included 5-pin captive screw connectors to the AUDIO OUT ports. Refer to the OmniStream User
Manual for wiring information.
3. Login to the decoder and click HDMI Output in the menu.
4. Scroll down to the Audio section and click the Analog Power toggle switch to enable it. When enabled, the
toggle switch will be orange. The Analog Power Status indicator, above the toggle switch, will be green. This
indicates that the external power supply is connected to the decoder.
Audio from the source will now be heard on the ANALOG OUT port of the decoder. Note that when audio is de-
embedded, it will not longer be audible using the HDMI OUT ports on the decoder.
Embedding audio will replace the existing HDMI audio source, normally heard on the output of the decoder.
The analog audio will be heard on the HDMI OUT port of the decoder.
Embedding Audio
1. Connect the power supply to the DC 48V connector on the decoder.
2. Connect the audio source to the AUDIO IN ports, using the included 5-pin captive screw connectors. Refer to
the OmniStream User Manual for wiring information.
3. Go to the decoder.
4. Click HDMI Output in the menu bar.
5. Scroll down to the Audio section and click the Analog Power toggle switch to enable it. When enabled, the
toggle switch will be orange. The Analog Power Status indicator, above the toggle switch, will be green. This
indicates that the external power supply is connected to the decoder.
Audio from the source will now be heard on the HDMI OUT ports on the decoder.
IMPORTANT: When using analog audio inputs on the OmniStream decoder, the decoder must
be powered using the 48V power supply (AT-PS-48083-C). This power supply is sold separately
and can be purchased from Atlona.

Conguring Redundant Streams
* Switching time will be dependent upon the network switch that is used, as well as the number of hops between
encoders and decoders on the network.
Mode Description
Off
Redundancy off; output will never switch to the backup stream.
Join Active
The decoder sends a join request only when the primary stream is lost or if the decoder
is manually switched to the backup stream. Switch time will not exceed 5 seconds.*
Join Always
The decoder joins both the Primary and Backup stream at the same time. Switch time
will not exceed 0.5 seconds.
During use, the decoder can be switched to another multicast stream. However, if the decoder encounters a missing
stream, during the switch and when redundancy is enabled, then this will cause the decoder to automatically failover
to the multicast source congured as the backup. To prevent the decoder from automatically making the redundancy
switch, when redundancy is enabled, a grace period can be entered. By default, the grace period is set to 0
seconds. If set to 0 seconds, automatic failover will occur if the stream is interrupted, for any reason.

Daisy-Chaining Encoders
Encoders can be daisy-chained to one another. This is particularly useful when only a single distribution point and
one display exists in a room. Daisy-chaining transforms multiple encoders into a single multiple-input encoder with a
single multicast IP address.
In the diagram below, three dual-channel OmniStream encoders are connected to a switch. In order to daisy-chain
them, they must be reconnected in a dierent conguration. Each encoder has been labeled with an arbitrary IP
address, for identication purposes.

3. Login to the encoder.
4. Click SESSION in the menu bar.
5. Create an encoder group for using each encoder in the chain. Refer to Encoder Grouping (page 76) for more
information. Since there are three encoders in this example, each encoder will be listed under the SESSION
page, as shown. Encoders can be added to an encoder group in any order.
To delete an encoder from the Members list, click the icon to the right of its IP address.
NOTE: Single-channel encoders do not support daisy-chaining. In addition, the OmniStream
R-Type Encoder (AT-OMNI-512) does not support daisy-chaining and cannot be combined with
OmniStream Pro daisy-chain congurations.
IMPORTANT: The optional OmniStream power supply (AT-PS-48083-C) must be connected to
each encoder that is daisy-chained, in order to supply the required power. Note that since each
encoder must use an external power supply, connection to a PoE switch is not required.

6. Click the Trigger drop-down list to select the trigger mode. Selecting the trigger mode will set how the
OmniStream encoder will respond when a source is disconnected/connected.
The diagram above shows a basic daisy-chain setup. The path of the A/V signal is identied with red arrows.
When encoders are daisy-chained, they function as one single encoder. In this example, daisy-chaining three dual-
channel encoders, creates a single “logical” encoder with six HDMI inputs.
When daisy-chaining encoders, the following rules apply:
• All encoders will stream content using the same multicast IP address. Therefore, the decoder must be
subscribed to this multicast IP address in order to display the content.
• Daisy-chained encoders can only display one source at a time. Click the Trigger drop-down list to determine
how the encoder will handle switching between sources.
• The last source that is connected will be the one that is displayed. However, this is only occurs if the Trigger
mode is set to input connected.
• Pressing the INPUT button, on the front panel of an encoder, will toggle between HDMI inputs.

OmniStream supports 128-bit Advanced Encryption Standard (AES) scrambling and is required for HDCP-encrypted
streams. Scrambling can be enabled or disabled through the web server, and can be applied to individual sessions.
In order for scrambling to function properly, it must be enabled on both the encoder session and all decoders
subscribed to a stream that is a part of a scrambled session. The scrambling key on both encoder and subscribed
decoder(s) must be identical. When enabled, the default scrambling key is “scrambling”.
Scrambling

5. Click the SAVE button at the bottom of the Stream window group to commit the changes.
IMPORTANT: If a user-dened key is specied, then it must be a minimum of eight
alphanumeric characters. Special characters and spaces are not permitted. Also note that if a
key is generated, the same generated key (on the encoder) must also be used on the decoder, in
order to de-scramble the signal.

Fast Switching
1. Login to the decoder and click HDMI OUTPUT in the menu.
2. Click the Fast Switching Enable toggle switch to enable this feature. When enabled, the toggle switch will be
green.
3. Enter the timeout interval, in seconds, in the Fast Switching Timeout(s) eld. If fast switching is enabled and
the decoder is switched to a dierent stream, but the stream is not present, then the decoder will hold the last
image on the screen. This image will continue to be displayed until either a new stream appears or the decoder
is switched to a dierent stream. Once the timeout interval has expired, the screen will go black. Setting the
timeout interval to 0 disables this feature and the last image will be displayed indenitely.
The VCx codec provides fast switching at resolutions up to 4K @ 60 Hz. This is an improvement over the VC-2
codecs that limited fast switching to 1920x1200. When the decoder resolution and frame rate are set to Auto,
VCx fast switching operates at the preferred resolution and frame rate of the display. In some cases, this preferred
resolution and frame rate might not be the maximum supported by the display. If fast-switching is desired at a
supported resolution and/or frame rate other than the preferred resolution and frame rate, the decoder can be
manually congured for those resolutions.
The fast switching time depends primarily on three things, when switching between streams: resolution, frame rate,
and bitrate. For example, a 4K60 stream operating at 750 Mb/s requires ~250 ms to switch. On the other hand, a
1080p stream operating at 750 Mb/s requires less than 50 ms to switch. The time it takes to switch is determined by
the amount of time it takes for all the data for a complete frame to be received by the decoder. To improve the fast
switching time, decrease the resolution, lower the frame rate, or increase the bitrate.
NOTE: The following table is only applicable when using the VC-2 codec.
Input Resolution (from Encoder) Output Resolution (AT-OMNI-121) Output Resolution (AT-OMNI-122)
1280 x 720p 1280 x 720p 1280 x 720p
1920 x 1080p @ 60 Hz 1920 x 1080p @ 60 Hz 1920 x 1080p @ 30 Hz
> 1920 x 1080p (up to UHD) 1920 x 1080p @ 60 Hz 1920 x 1080p @ 30 Hz
IMPORTANT: If Fast Switching is enabled, latency increases from 0.5 frames to 1.5 frames.
When using Fast Switching mode, the output resolution will be 1920x1080p, regardless of the
source resolution. Also note that 1080i is not supported in Fast Switching mode. Also note that
Slate / Logo Insertion and Text Insertion will be automatically disabled when Fast Switching is

Fast Switching FAQs
Question: Does fast switching work between streams of dierent resolutions?
Answer: Yes. Fast switching can be used between streams with dierent resolutions and frame rates.
Question: Does fast switching work between HDR and SDR streams?
Answer: Yes, fast switching can be used between HDR and SDR streams; however, it’s important to note that
some color artifacts may appear during the switch.
Question: Does fast switching work between single streams and multiviews or between multiviews?
Answer: No. Due to the way multiviews work, fast switching is not supported. However, it is not necessary to
change the fast switching setting – the decoder will switch as fast as possible between multiviews
and return to fast switching when single streams are used.
Question: Does fast switching work on video walls?
Answer: No. Fast switching is not supported when using video walls.

Conguring a Static IP Address
If an encoder is unable to recognize a DHCP server, within 60 seconds after being connected to a network,
the encoder is placed in Auto IP (APAPI) mode and assigned an IP address within the range 169.254.xxx.xxx.
In order for the encoder to be recognized on the network, it will need to be assigned a static IP address.
There will be situations where it is desirable for the encoder to be assigned a static IP address. Some IT
environments prefer this method, as opposed to having a DHCP server dynamically assign IP addresses. In other
cases, an encoder that is in Auto IP (APAPI) mode will need to have a static IP address assigned before it can be
connected to a network with a specied subnet.
IMPORTANT: Under Microsoft Windows, make sure to 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.
Prepare the Encoder and the PC (Auto IP Mode only)
General Static IP Conguration
1. Go to the encoder/decoder, click NETWORK in the menu bar, then click the DHCP Mode drop-down list and
select Static.
2. Enter the desired IP address in the IP address eld.
• 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.
• Connect an Ethernet cable from the PC, to one of the Ethernet ports on the encoder. If using the AT-OMNI-112,
the Ethernet cable can be connected to either ETHERNET 1 or ETHERNET 2 port.
• Congure the PC to a static IP address that is on the same subnet as the encoder.
Device Operation

2
IMPORTANT: Dual-channel encoders provide two Ethernet interfaces. It is important to
understand that even though they are separate physical interfaces, they should be congured
as a single interface. For example, if conguring the encoder in static mode, make sure both
Network 1 and Network 2 are congured with a static IP address. Network 1 and Network 2
should not be congured in dierent modes.

802.1X Authentication
802.1X is a server-based port authentication which restricts unauthorized (rogue) clients from connecting to a Local
Area Network through a public port. In its simplest form, 802.1X usually involves three parties: supplicant (client
device), authenticator (Ethernet switch or WAP), and an authentication server. Before the device is permitted on
the network, port communication is restricted to Extensible Authentication Protocol over LAN (EAPOL) trac. If the
device passes the authentication process, the authentication server noties the switch, allowing the client to access
the LAN. The illustration below shows the basic architecture.
Three options are available on both the OmniStream encoder and decoder.

WARNING: Connecting an 802.1X-enabled encoder to a network without an active or

expected message is returned from a RADIUS server. If it is unclear as to whether the network
uses 802.1X authentication, consult the IT administrator for assistance.

Layout and Operation
The illustration below shows multiple OmniStream units that are connected on the same network as the Velocity
Device Manager. The OmniStream Virtual Matrix is what is known as a crosspoint matrix. By denition, a crosspoint
matrix is a conguration that allows the routing of multiple input signals to various output destinations. In a
crosspoint matrix, each intersection (or crosspoint) between an input and an output can be controlled to connect
or disconnect signals, enabling exible signal distribution. This eliminates the need to change existing physical
connections.

To understand how a crosspoint matrix works, let’s duplicate a crosspoint matrix with a set of switch components.
The diagram below represents a basic 4x4 crosspoint matrix. Each endpoint is marked as either an ENCODER or a
DECODER, with encoders aligned along the rows and decoders along the columns. This arrangement mirrors the
layout used by the OmniStream Virtual Matrix. Note that all switches are open, meaning no encoder is currently
connected to any decoder. Each switch has been labeled.

Device Operation
Next, let’s close one of the switches. In this example, closing switch SW8 will route the signal from ENCODER 2 to
DECODER 4. See Figure 1.2 for reference.
Furthermore, closing SW5, SW6, and SW7 will route the signal from ENCODER 2 to DECODER 1, DECODER 2, and
DECODER 3, as illustrated in Figure 1.3.
Note that routing a dierent source to a decoder that is already in use will display the new source signal.
For instance, in Figure 1.3, closing SW12 will route the signal from ENCODER 3 to DECODER 4, even though SW8 is
closed.
Returning to the OmniStream Virtual Matrix, in Velocity, the illustration below shows the source signal from the
AT-OMNI-111 encoder routed to the AT-OMNI-121 decoder. The icon indicates that these two devices are
communicating. Clicking the icon will disable the route and the icon will be displayed.

OTHER > PTP page
Network window group
The PTP page provides options for adjust Precision Time Protocol (PTP) for AES67 audio streams. PTP is used by
AES67 to keep all audio streams synchronized.
For a system utilizing PTP, all devices undergo an automatic self-election process to choose the interface to be used
as the PTP grandmaster (GM) clock, based on the accuracy of the device’s clock and the device’s congured priority.
A lower priority number means the unit is more likely to get selected as the GM.
IMPORTANT: If a new device is added to the network and the GM changes, a brief outage will
be experienced while all connected devices synchronize with the new clock. Because of this,
Atlona recommends that one unit gets manually dened as the GM and have both Priority 1
and Priority 2 elds be set to 1.

OTHER > PTP page
Network window group
The PTP page provides options for adjust Precision Time Protocol (PTP) for AES67 audio streams. PTP is used by
AES67 to keep all audio streams synchronized.
For a system utilizing PTP, all devices undergo an automatic self-election process to choose the interface to be used
as the PTP grandmaster (GM) clock, based on the accuracy of the device’s clock and the device’s congured priority.
A lower priority number means the unit is more likely to get selected as the GM.
IMPORTANT: If a new device is added to the network and the GM changes, a brief outage will
be experienced while all connected devices synchronize with the new clock. Because of this,
Atlona recommends that one unit gets manually dened as the GM and have both Priority 1
and Priority 2 elds be set to 1.

Notes on Dual Streaming
Frequently Asked Questions
Dual streaming is supported exclusively on the AT-OMNI-111 and allows two unique streams per HDMI input at
dierent bit rates and resolutions. Dual streaming on the AT-OMNI-111 provides two benets:
• To allow two streams at two dierent resolutions for use with the Multiview capabilities of the AT-OMNI-121.
• To provide another option for bandwidth management, where users could, for example, choose to only use
lower-resolution, lower-bitrate streams in scenarios where the stream needs to traverse multiple switches.
Question: What is the maximum video bit rate of each of the two streams?
Answer: The maximum video bit rate for the encoder is 900 Mb/s and can be allocated across the streams.
If only one stream is being used, then the maximum bandwidth (900 Mb/s) will be availble. If two
streams are being used, then the bandwidth allocation will need to be managed so that the
combined bit rate does not exceed 900 Mb/s. The encoder will generate a notication if the
maximum bandwidth of 900 Mb/s is attempted from an encoder.
Question: Are there bit rate recommendations for each stream?
Answer: The ideal bit rate for each stream depends on the resolution of the stream. The following guidelines
are oered, and the bit rate can always be adjusted as desired.
Resolution Recommended Bit Rate
4K60 4:4:4 750 Mb/s
4K60 4:2:0 350 Mb/s
4K30 4:4:4 350 Mb/s
1080p60 4:4:4 150 Mb/s
Question: What are the scaling capabilities of each stream?
Answer: The AT-OMNI-111 has two independent scalers – one for each stream. The scaler on Encoder 1 is
capable of scaling up and down to resolutions as high as 3840x2160. The scaler on Encoder 2 is
capable of scaling up and down to resolutions as high as 1920x1080. For each scaler, there is a list
of resolutions that can be selected. Arbitrary scaling resolutions cannot be created and used.
Question: Does each stream have its own session?
Answer: The AT-OMNI-111 has six sessions that can be fully congured. Each session can utilize either of
the two encoders, and the most common use case will be to have Stream 1 using Encoder 1 and
Stream 2 using Encoder 2, creating two unique streams at two resolutions. However, there is
nothing that prevents using Encoder 1 or Encoder 2 on both sessions.

FEC Details
Matrix Size, Overhead, and Latency
FEC and Video Bitrate
• FEC can only work if a single packet from each row/column is 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 conguration 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.
• The bitrate congured 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:
• The following table provides a few examples of how this works.
Video rate =
Configured bit rate
1 +
Rows + Columns
Rows x Columns
FEC rate = Configured bit rate - Video rate

Appendix
FEC, Latency, and Lip Sync
• In order for FEC to work, the matrix must be lled 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 signicant 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.
» Video - additional video latency for enabling FEC using various matrix sizes.
• 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 congured for 450 Mbps, FEC 10x10; Audio is 2 channel PCM, 192 kHz, FEC 1x4: 6.40 ms – 7.81 ms
= -1.41 ms
» Video congured for 900 Mbps, FEC 10x10; Audio is 2 channel PCM, 48 kHz, FEC disabled: 6.40 ms – 0 ms
= 6.40 ms
» Audio - additional audio latency for enabling FEC using various matrix sizes.
Congured bit rate 4x4 10x10 20x20
900 Mbps 0.64 ms 3.20 ms 11.74 ms
450 Mbps 1.28 ms 6.40 ms 23.47 ms

Appendix
Dierentiated Services Code Point (DSCP) is a method of managing network trac, in addition to providing Quality
of Service (QoS) within the Layer-3 (Network Layer) of the OSI network model. DSCP uses the 6-bit Dierentiated
Services (DS) eld in the IP header in order to determine packet classication/priority. Normally, all routers and
switches will forward network trac to the proper destination with the same priority, no matter what type of data it is.
This methodology is what is known as Best Eort.
The Best Eort setting will provide normal priority for data packets, while other settings will raise the priority on
data packets. However, it should be noted that a higher priority setting on one type of data type may also result in
data packet loss for other data types, depending upon network trac.
When QoS or dierentiated services policy is used, all network devices such as routers, networks switches, and
end-devices must be congured properly in accordance with QoS policies on the network. There are two main
methodologies for tagging trac: Assured Forwarding (AF) and Class Selectors (CS).
The tables below provide a list of the available selections and their description.
IMPORTANT: Consult the IT administrator as to what methods to use and the required settings
for each encoder on the network.
