Frequently Asked Questions - OMNI-122 Atlona

How do I set up the OMNI-122 for the first time?

Connect an Ethernet cable from the decoder to a PoE-capable switch. If PoE is not available, use the optional 48V DC power supply (AT-PS-48083-C). Connect HDMI cables from the HDMI OUT ports to displays. Use the Atlona Management System (AMS) to discover and configure the decoder.

Can I use the OMNI-122 to create a video wall?

Yes. Configure each decoder in the video wall via AMS: set the output resolution, enable Video Wall, define display width/height, and set horizontal/vertical start positions. Use bezel compensation and rotation if needed.

What is the difference between unicast and multicast mode?

Unicast mode sends a stream from one encoder to one decoder (like an n×1 switcher). Multicast mode allows one encoder to send to multiple decoders (like a matrix switcher). By default, decoders are in multicast mode.

How do I enable AES-128 encryption?

In AMS, go to the encoder's SESSION page and enable Scrambling. On the decoder, go to HDMI OUTPUT > Descrambling and enter the same key (minimum 8 alphanumeric characters). You can also set scrambling via the Virtual Matrix.

How can I reset the decoder to factory defaults?

Press and hold the ID button on the front panel for about 30 seconds until all LEDs turn off. Alternatively, in AMS under DEVICE INFO, click FACTORY RESET and choose desired options.

Does the OMNI-122 support redundant streams?

Yes. Configure redundancy in the Virtual Matrix: select backup mode (Join Active or Join Always) for video and/or audio. The decoder can switch to a backup stream if the primary fails.

How do I de-embed audio from HDMI?

Connect the 5-pin captive screw connector to the AUDIO OUT port. In AMS, go to HDMI OUTPUT > Audio and enable Analog Output. Note: the decoder must be powered by the 48V DC supply when using analog audio inputs.

What is the warranty period for the OMNI-122?

The OMNI-122 has a 10-year limited warranty for products purchased on or after June 1, 2013. Warranty covers defects in materials and workmanship. Proof of purchase is required.

Can I control the decoder via RS-232?

Yes. Use the included Phoenix terminal block to connect RS-232 devices. In AMS, go to SERIAL to configure baud rate, mode (Output or tcpproxy), and store commands like Display On/Off. Bidirectional control is supported in unicast mode.

How do I update the firmware?

In AMS, go to DEVICE INFO and click UPDATE FIRMWARE. Drag the .v2pup firmware file to the upload area, select it, and click UPDATE FIRMWARE. If updating from version 1.0, first update to 1.1 then to 1.2.1.

Installation

RS-232 Connections

Both the AT-OMNI-121 and AT-OMNI-122 provide RS-232 over IP, allowing communication between an automation system and an RS-232 device. This step is optional. Note that different Phoenix connectors are provided with each product.

1. Use wire strippers to remove a portion of the cable jacket.

2. Remove at least 3/16" (5 mm) from the insulation of the RX, TX, and GND wires.

3. Insert the TX, RX, and GND wires into correct terminal on the included Phoenix block. If using non-tinned stranded wire, press the orange tab, above the terminal, while inserting the exposed wire. Repeat this step for the TX, RX, and GND connections.

AT-OMNI-121

AT-OMNI-122

NOTE: Typical DB9 connectors use pin 2 for TX, pin 3 for RX, and pin 5 for ground. On some devices, pins 2 and 3 are reversed.

IR Connections

The same port that provides RS-232 connections also supports bidirectional IR pass-through, allowing a device to be controlled from either the headend or the decoder endpoint. This step is optional. Either the top three or bottom three set of terminals can be used for IR. Only the RS-232 2 port (bottom set of connectors) supports both RS-232 and IR. Therefore, this port must be used for IR connections.

IR emitter configuration

Configuration

Discovery using AMS

It is recommended that the Atlona Management System (AMS) be used to configure and control OmniStream devices. AMS uses multicast Domain Name Server (mDNS) to automatically configure 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.

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, 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 22) for more information on configuring an encoder 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.

• Click the desired decoder from the Unassigned device list.

Once the unit is selected, the control interface for the encoder will be displayed. The illustration below shows the DEVICE INFO screen for an AT-OMNI-122 decoder.

Configuring 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, 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 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. Configure the PC to a static IP address that is on the same subnet as the decoder.

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.

1. Login to AMS. Refer to Accessing Decoders in AMS (page 19) if necessary.
2. Locate the decoder under the Unassigned section within AMS.
3. Click on the device.
4. Under AMS, click the NETWORK tab.

1. Click the DHCP Mode drop-down list and select Static.

1. Enter the required network information for the decoder in the IP Address, Subnet, and Gateway fields.
2. Click the Save button in the bottom-right corner, to apply the changes.
3. Disconnect the decoder from the PC and connect it to the network.
4. The decoder is now ready for use.

Basic Operation

LED Indicators

The following table provides a listing of front-panel LED indicators and their status:

LED Description
PWR Off • If	using a PoE switch, make	sure that the port on the switch that is connected to the encoder, has PoE enabled. When the encoder is powered using PoE, the PWR indicator will be green.Check the Ethernet cable for possible damage or loose connections.Connect the optional 48V DC power supply (available from atlona.com) to the encoder. When using an external power supply, the PWR indicator will be red.
	Red • The decoder is booting.
	Green • The decoder is ready.
LINK 1 / 2 Red	• The optional 48V DC power supply is connected, but no Ethernet cables are connected between the switch and the ETHERNET port(s).Check the Ethernet cable for possible damage or loose connections.
	Green • Link integrity is good between the encoder and the network.

Rebooting OmniStream

To reboot the OmniStream decoder, press and release the recessed button, on the far-right side of the unit, using a small, pointed object. Rebooting the decoder does not reset the decoder to factory-default settings.

ID Button

This feature is not available on the single-channel OmniStream decoder (AT-OMNI-121).

The ID button serves two functions:

1. Sends a broadcast message, over the network, to any devices that may be listening.
2. Resets the encoder to factory-default settings.

Broadcast Messaging

Press and release the ID button to send a broadcast notification over the network to any devices that may be listening.

Reset to Factory-Default Settings.

1. Press and hold the ID button for approximately 30 seconds.
2. The LED indicators on the front panel will flash, then turn "off."
3. The encoder is now reset and will need to be reconfigured.

WARNING: Performing a factory-default reset will erase all user-programmed settings from the encoder. IP settings are not preserved.

Unicast Mode

The term unicast is used to describe a configuration 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 different 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.

1. Login to AMS. Refer to Accessing Decoders in AMS (page 19) if necessary.
2. Go to the encoder AMS interface. Refer to the OmniStream Single-Channel / Dual Channel A/V Encoder User Manual, if necessary.
3. Click SESSION in the menu bar and scroll down to the Video section.
4. Enter the IP address of the decoder in the Destination IP Address field. If using dual-channel encoders, repeat this process for each session.

Basic Operation

1. Go to the decoder AMS interface.
2. Click IP INPUT from the menu.
3. Remove the IP address from the Multicast Address field.
4. Click the SAVE button to commit changes.

1. Unicast setup is complete. The decoder unit will now receive streams exclusively from the encoder containing the IP address of this decoder.

Multicast Mode

The term multicast is used to describe a configuration 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.

1. Login to AMS. Refer to Accessing Decoders in AMS (page 19) if necessary.
2. The AMS Dashboard will be displayed.
3. Click the ≡icon, in the upper-left corner of the AMS Dashboard.
4. Click Virtual Matrix from the fly-out menu. Refer to The Virtual Matrix (page 85), if necessary.
5. Locate the desired encoder in the Virtual Matrix, as shown on the next page.
6. Create a cross-connection to the desired decoder. When a cross-connection is created, AMS will automatically assign a multicast IP address to both the encoder and decoder. By default, AMS automatically assigns a multicast IP address to each OmniStream encoder and decoder.

Refer to the illustration on the following page, if necessary.

Configuring 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.

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.

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) traffic. If the device passes the authentication process, the authentication server notifies the switch, allowing the client to access the LAN. The illustration below shows the basic architecture.

NOTE: As of this writing, AMS does not currently support 802.1X configuration. This will be added in a future release of AMS. Contact Atlona for more information. Use the following instructions to set up video mode using the OmniStream web GUI.

WARNING: Connecting an 802.1X-enabled decoder to a network without an active or operational authentication server, will result in an encoder that does not function until the 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.

Slate / Logo Insertion

Slate / logo insertion is managed from within AMS. The difference between a “slate” and “logo” is in the size of the image and how it is used: Logos are classified as smaller, low-resolution images that can be positioned at specified locations on the screen. Slates occupy the entire screen. Note that while logos may be used as slates, the image quality will be degraded, as the image will be scaled to fill the screen.

Slate / logo insertion can be performed on both the encoder and decoder. When configured on the encoder, the image that is displayed on the output (decoder) will be from the encoder IP address(es) to which each decoder is subscribed. When configuring on the decoder, the presence of the image is specified on the (individual) HDMI output. Refer to the OmniStream Single-Channel / Dual Channel A/V Encoder User Manual, for information on managing slate / logo insertion on encoder units.

NOTE: When using 4K images, the image width must not exceed 30% of the horizontal resolution.

Creating Video Walls

The following example illustrates how to configure a 2x2 video wall.

Below, four decoders are subscribed to a single encoder and are displaying the same image on all four displays. The video source is 3840 x 2160. In order to create a single image using all four displays, each source image will need to be cropped and scaled to one-fourth of the total image resolution. The “crop and scale” feature will be used to provide the correct output. Also note that the top two displays have been accidentally mounted upside-down. The “rotate” feature can be used to correct such a scenario and will be illustrated in the following procedure.

Configuring Redundant Streams

OmniStream decoders have the ability to identify missing streams, should an input be disconnected from the encoder, and will recover the image almost instantaneously. The decoder can access the same stream from two separate multicast addresses and switch between them, when necessary.

1. Login to AMS and access the Virtual Matrix. Refer to The Virtual Matrix (page 85) for more information.
2. In the Virtual Matrix, locate the decoder to be configured for redundancy.
3. Click the Options button for the desired decoder. In this example, the decoder in the upper-left corner of this matrix will be used. The Crosspoint Options dialog box will be displayed.

1. Select the backup mode for Video Redundancy and/or Audio Redundancy from the Backup Mode drop-down lists. Refer to the table below, for a listing and description of the available modes.

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.

* 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.

Redundancy Grace Period

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 configured 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. Refer to Configuring Redundant Streams (page 54) for more information on enabling or disabling redundancy.

1. Login to AMS. Refer to Accessing Decoders in AMS (page 19) if necessary.
2. Click HDMI OUTPUT in the menu bar.

PTP page

The PTP tab 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 configured priority. A lower priority number means the unit is more likely to get selected as GM.

NOTE: 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 defined as the GM and have both Priority 1 and Priority 2 fields be set to 1.

The Virtual Matrix

1. Click the ≡icon, in the upper-left corner of the AMS Dashboard.
2. Click Virtual Matrix.

1. The OmniStream Virtual Matrix page will be displayed.

Layout and Operation

The illustration below, shows a multiple OmniStream units (encoders and decoders). The Virtual Matrix is organized into rows and columns.

The blue circle with the checkmark indicates that these two OmniStream units are connected to one another. The second column identifies a dual-channel decoder (AT-OMNI-122). The third row shows a dual-channel encoder (AT-OMNI-112). In this example, the source signal on HDMI 1 IN (encoder) is being sent out, over the network, and will be displayed on HDMI 1 on the decoder. This will create a cross-connection, which connects both the encoder and decoder together.

- Creating a cross-connection

To route an input on an encoder to an output, locate the row and column where an input and output intersect, then click the square with the dots around it.

- Removing a cross-connection

To remove a cross-connection, click on the desired circle icon with the check mark symbol. The square with the dots around it will be displayed indicating that the cross-connection has been removed.

• To view the individual streams for video, audio, and data, click the icons on the upper-left corner of the screen.

When these icons are clicked, the associated icons will be displayed in the rows and columns of the Virtual Matrix.

Symbol Description
V	Video only
A	Audio only
D	Data only
✓	Connected; not all signals are active
✓	Connected; all streams are being used

IMPORTANT: R-Type and Pro compatibility: R-Type encoders (AT-OMNI-512) and decoders (AT-OMNI-521) operate in Video Mode, only. Pro encoders can be set to either Video Mode or PC Mode. Video Mode is incompatible with PC Mode. Therefore, in order for both R-Type and Pro encoders/decoders to work within a system, Pro encoders/decoders must be set to Video Mode. Refer to Setting the Video Mode (page 43) for more information.

• Click the Video, Audio, and Data icons to return to the normal view.
• Since only HDMI (both audio and video) is being used, the V (video) and A (audio) icons are displayed. The blue circle with the checkmark indicates that the cross-section has been created. However, not all streams are being used. Refer to the chart below.
• This illustration also shows that the data stream (the icon with two arrows and three dots), which is used for control, is also being used and is displayed as a dark-blue circle with the letter "D".
• The icons in the upper-left corner can also act as a filter. This allows for a clear breakdown of where signals are being routed and is useful when several encoders and decoders are used on a network.

FEC Details

Matrix Size, Overhead, and Latency

• 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 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:

$$ \text { Video rate } = \frac {\text { Configured bit rate }}{1 + \left(\frac {\text { Rows } + \text { Columns }}{\text { Rows } \times \text { Columns }}\right)} $$

$$ F E C \text { rate } = \text { Configured bit rate } - \text { Video rate } $$

- The following table provides a few examples of how this works.

FEC / matrix usage Configured bit rate Used for video Used for FEC

FEC disabled 900 Mbps 900 Mbps 0 Mbps
FEC enabled, 4x4 900 Mbps 600 Mbps 300 Mbps
FEC enabled, 10x10 900 Mbps 750 Mbps 150 Mbps
FEC enabled, 20x20 900 Mbps 818 Mbps 82 Mbps
FEC enabled, 4x4 450 Mbps 300 Mbps 150 Mbps
FEC enabled, 10x10 450 Mbps 375 Mbps 75 Mbps
FEC enabled, 20x20 450 Mbps 409 Mbps 41 Mbps

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.

» Video - additional video latency for enabling FEC using various matrix sizes.

Configured 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

» Audio - additional audio latency for enabling FEC using various matrix sizes.

Format 1x4 2x4 4x4 10x10
2 channel PCM, 44.1 kHz	34.01 ms	68.03 ms	136.10 ms	850.30 ms
2 channel PCM, 48 kHz	31.25 ms	62.50 ms	125.00 ms	781.30 ms
2 channel PCM, 96 kHz	15.63 ms	31.25 ms	62.50 ms	390.60 ms
2 channel PCM, 192 kHz	7.81 ms	15.63 ms	31.25 ms	195.30 ms

• 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
