Introduction
Product Description
The iCap Connect AV650 is EEG’s 1RU SDI encoder that supports native 12G caption encoding and decoding. As
the newest generation of the EEG iCap Encoder, the AV650 is equipped to future-proof any production studio or
event space looking to caption in 4K resolution.
With the AV650, users can now overlay open captions on a 4K display, or in ATSC 3.0 for in-room monitor
accessibility. The SDI signal with captions can also be sent to a separate streaming media encoder, and then
converted to RTMP for a live streaming workflow.
The AV650 is the ideal solution for event production companies looking to expand their audiences by having
the flexibility to work with broadcast, live stream, and in-room spaces, while having the option to encode in 4K.
List of Features

Encoder Setup
Quick Network Setup
To use iCap or Lexi and to access further features on the encoder’s web interface, you must first select Network
Settings from the front panel LCD menu and set up the encoder on your network.
✔Use a Static IP address on your network to assign the Encoder (recommended). It doesn’t have to
be, and in most cases should not be, a publicly routable IP address.
✔Program a gateway address – the gateway address is typically the local network address of your
router. This is necessary if you plan to connect out of your local network to iCap, Lexi, or any other
application from the iCap Encoder.
✔Program a Subnet Mask for your network
✔Important for Lexi use only: Program your network to allow outbound connections to
https://eegcloud.tv on port 443. Your encoder must also have a valid DNS server configured under
the Network tab on the web portal. See additional Lexi setup instructions on Page 6.
As an alternative to these recommended steps you may also set up the encoder for DHCP – Selecting DHCP
will automatically pull available IP, gateway, and subnet information from your network. IMPORTANT: With
DHCP, your encoder’s assigned IP may change on its own which will affect how you access the web interface
for your encoder.
Video Input/Output
Put SDI video into the encoder. Output captions will appear on the SDI video output. Reference the Rear
Panel Diagram located in the Hardware Reference for a diagram of the rear-panel connector.
Test Captions
With video input connected to the encoder, you can send a stream of encoder-generated test captions to the
output video to ensure proper initial setup of the encoder. To send test captions navigate to Utilities > Test
Captions > Enable > On and a stream of test caption text should appear on the output of your encoder. Note
that video input is required to send test captions.

Setting Audio Levels
Your program audio source is typically embedded in the standard video input to your encoder. Audio may also
originate from a separate Analog or AES source (XLR connector input to encoder). To send this program audio to
captioners through iCap, you must first configure the audio settings through the front panel menu of the encoder.
From the main menu go to Audio Setup > Audio Mix and set to Stereo or Surround appropriately. Next, visit
Audio Setup > Peak Level and ensure the audio level peaks at around 80% and does not warn “Clipping!” This
step is crucial for ensuring that quality audio is being sent to the captioner (quality audio = quality captions).
If your audio levels are too low, or too high – you can achieve an appropriate level by adjusting the audio source
itself or simply adjusting the source audio level from the encoder front panel LCD menu Audio Setup > Scale
Audio which allows you to scale the audio up or down in 6 decibel increments.
Detailed Explanation of Audio Setup Menu Options
Input Select
Selects whether the input audio format is analog, AES digital or embedded audio.
Use the LEFT and RIGHT keys to select the correct format, then press ENTER to exit
and apply changes or CANCEL to exit and cancel changes. The AV650 does not
currently support direct input of Dolby® E or other compressed audio signals.
Peak Level
Dynamically displays the peak signal level at the audio input. A warning message
will be displayed when clipping is detected at the input. For optimal sound quality,
the peak level bar should reach at least 60% across the screen, but should never
display “Clipping!”
Scale Audio
Adjusts the audio input level without adjusting the output level of your source. The
built-in digital input trim can boost or cut the audio input level up by as much as 12
dB.
Audio Group
Selects the SDI embedded audio channel group that the iCap™ mix is sourced from.
Up to 4 channel groups can be carried on an SDI signal, though most commonly
Group 1 carries the primary audio program. Applies only when embedded audio
input is selected.
Audio Mix
Selects whether the iCap™ mix is being created from a Stereo or Surround channel
group. Choose “Stereo” to select a mix of the left and right channels (1 & 2 or 3 & 4
within the selected Audio Group, according to the Stereo Channel setting), or
“Surround” to select a mix of the left, right, and center channels (1, 2 & 3 within the
selected Audio Group). Applies only when embedded audio input is selected.
Stereo Channel
Selects whether the iCap™stereo mix is being created from channels 1 & 2 or
channels 3 & 4 within the selected Audio Group. Applies only when embedded
audio input AND stereo audio mix are selected.

Accessing Your Encoder’s Web Interface
Your Encoder’s web interface can be accessed through any computer on your local network and controls many of
your encoder’s applications, configurations, and features (see Security Settings and Password Protection below for
instructions on how to secure access to the web interface). You will see it referenced many times throughout this
manual.
The encoder must be connected on your network to access the web interface (reference Quick Network Setup).
The web interface is accessed by entering the IP address assigned to your encoder in your computer’s web
browser. Note that if you set the encoder up with DHCP, the address can change at will and you should check the
IP from the front panel of your encoder at System Setup > Network > IP Address to ensure you are using the
correct IP to access the web interface.
Security Modes and Password Protection
To limit access to the encoder’s web interface, you may set up a password through the front panel of your
encoder via Setup > Security > Security Mode. This password will be required for access to the encoder’s web
interface, not the front-panel LCD menu. See below for a complete description of all Security Mode options. iCap
connections are still allowed in all modes.

iCap Setup and Testing
This section will walk you through a basic test run of iCap and point out the important information your captioner
needs from you to get started. For sections that require you to access the iCap admin site – iCap Admin credentials
are supplied by EEG at the time of encoder purchase/rental along with your unique access code and is accessed at
https://www.eegicap.com/iCapAdmin. If you did not indicate iCap usage at the purchase of your encoder, contact
technical support at 516-293-7472 to be set up with iCap.
1. Connect iCap From the Encoder’s Web Interface
✔Select iCap from the menu on the left and confirm that the Company Name, User Name, and
Password are all present and correct.
✔On the same page confirm that iCap Status says Connected. Additionally, the iCap LED on the front
panel of your encoder should be green. This also means the encoder is connected to iCap.
✔If all information is correct and the status does NOT say Connected – try clicking the Start button found
on this page to connect to the iCap Network. An iCap Connectivity indicator light on the left face of the
encoder will also show green when iCap is connected and red if not connected.

2. Know Your iCap Access Code:
✔Your Access Code is what you provide to your captioner so that they can Access your program audio
and provide live captions through iCap.
✔Your unique Access Code can be found in the shipping documentation provided with your Encoder. It
may also be found by logging into the iCap Admin website at eegicap.com/iCapAdmin
✔ONLY “share” your Access Code with your caption service provider in the iCap Admin site. Your access
code may already be shared with them in iCap Admin if you provided the information to EEG as part of
your order. This can be verified in iCap Admin.
3. Coordinate Testing with Your Caption Service Provider
This step requires your caption provider to connect to your encoder from their iCap software. You MUST connect
your audio/video input to the encoder BEFOREHAND.
✔Once you’ve provided your access code to the captioner and connected your program video/audio to
the encoder you will test your connection to ensure audio is reaching them and caption data is coming
in.
✔Enter the iCap Admin portal. In the Users tab - confirm audio status for your encoder says “Audio OK”
(see figure 3) - this means your captioner is receiving Audio. If the Status says “No Listeners” it means
that the captioner has not yet connected to your access code and you should verify that they have
done so. The Users tab shows all users connected to your encoder and confirms their status.

✔Once you’ve confirmed the audio - click on the Access Codes tab to confirm incoming CC Activity from
your captioner. Once the captioner presses “Start” on their iCap software the CC Activity in iCap Admin
should read “Active” (see figure 4). Alternatively, confirm the CC LED on the front panel of your encoder is
green. This means that your encoder is receiving caption data from your captioner.
Figure 4: iCap Admin Access Codes Tab with CC Status
✔iCap Audio and Caption activity can also be verified locally by taking the following additional measures in
the web interface.
●Check the Audio Packets Sent under the iCap menu in the encoder web interface. If the number is
growing then Audio is being sent to the captioner. If it says 0, check with your captioner to ensure
they have connected.
●Check caption activity by selecting Logs from the side menu on the encoder web interface. Then look
for iCap, and select the log with today’s date. The iCap log will show some communication data which
means that captions are being received.
●Alternatively, you can view the “Clone” logs section which will show all binary commands sent - also
indicating captions are coming through the connection.

Other Live Captioning Methods
Modem
Standard RJ-11 connection. Connect to a phone line to enable dial-up captioning and provide your captioner with
the telephone number associated. Using a PBX or other digital non-POTS system is NOT recommended - many of
these are not compatible with modem communications.
Telnet
Enable Telnet via the encoder’s web interface and select a port. Configure your firewall to allow a captioner to get
to your encoder on the designated port and then give your caption service provider the port number and public
IP address.
RS-232 / RS-422 (Teleprompters or Other Devices)
See hardware section for cabling detail. Serial port settings are controlled through the web interface of the
encoder by selecting Serial Ports from the left side menu or by navigating to System Setup > P1 Mode from the
front panel LCD menu of the encoder. The AV650 supports RS-232, RS-422, and RS-422 Sony (with RS-422 and
RS-422 Sony options configurable on Port 1 only). Default settings are 1200 baud, odd parity, and 7 data bits.
Customized settings are sticky after power cycles. Modem will automatically take priority when active so that the
prompter can be overridden as desired.

Common Applications
Caption Bridging
Caption bridging copies captions in either direct from/to the source video (AUX) from/to the master video output.
This happens automatically when you have a captioned video input connected to one input and a video with no
caption data to the other. The front panel LCD screen will indicate when the encoder is in Bridging mode.
Dual Encoding (Two Video Paths)
The AV650 can caption to two independent video channels, embedding the same closed captions in both
channels. Any two supported video standards can be combined on the inputs to produce closed-captioned video
on the respective outputs. For example, if 2160p60 12G-SDI is present on the Main input and 1080p60 3G-SDI is
present on the Aux input, Main Out 1 will be closed-captioned 2160p60 12G-SDI and the Aux output will be
closed-captioned 1080p60 3G-SDI.
GPI Relocation
GPI Relocation allows on-command placement control of closed captions on your output to avoid blocking
essential action such as screen crawls and emergency information. You can control this feature by accessing the
Main section of the side menu of the encoder web interface and scrolling down to the GPI settings at the bottom.
The screen is mapped into 15 regions from top to bottom that can be protected with the use of GPI settings. If
you are creating a GPI switch and require a diagram of the GPIO Pinout – see the GPIO pinout / wiring detail
found in the Hardware Reference section of the manual

Scoreboard Interface for Stadiums (Caption Text Server Module)
The Scoreboard Interface module is an add-on component that produces a TCP/IP-accessible stream of the
decoded caption output from the Master video signal.
To determine if Text Server is installed on your unit, access your encoder’s web interface, look for an entry that
says Text Server on the left side menu and select it.If you are prompted for a license key, the feature is not
installed and can be purchased by contacting the EEG sales team.
To access closed caption data from the encoder unit with the Scoreboard Interface installed, utilize a TCP/IP
socket interface configured with the following settings.
✔For the IP address to connect to, use the IP that you have set on the front panel on the decoder
✔unit System Setup > Network > IP Address. The receiving unit must be a member of the same subnet as
the encoder.
✔For the port number to connect to, use 2400.
If these settings are correct, the Scoreboard Interface should accept your connection immediately. At this point,
you will receive ASCII text data over the connection which is a copy of the current CC1 caption data.
The output text is formatted using blank spaces and line breaks to approximate the intended appearance of the
CC1 captioning on a 608-compliant decoder. When you are ready to stop receiving the caption text, simply
disconnect at any time. You may connect multiple clients to the Streaming Caption Text Server simultaneously,
but it is better to remove connections that are not in use, as a very large number of simultaneous connections
could eventually have a negative effect on the system resource usage on the encoder or decoder unit.

Timed Playout of Caption Files (CCPlay Module)
CCPlay inserts caption data from imported text or binary files into the encoder’s SDI video output. The caption
data files contain time codes, and insertion into the video can be synced to ANC VITC (embedded in the SDI video
input) or timed with a self-generated video frame clock. CCPlay also allows you to schedule files for future playout
and shift time codes to adjust caption timing. A wide range of caption and subtitle file formats are supported,
including ECF, SCC, SRT, CAP, TT, WebVTT, and more. CCPlay is controlled primarily through the encoder’s web
interface but can also be controlled remotely through an HTTP API - for more information on this API point your
browser to http://{your-encoder’s-ip}/ccplay/api
To determine if CCPlay is installed on your unit, access your encoder’s web interface, look for an entry that says
CCPlay on the left side menu and select it.If you are prompted for an access key, the feature is not installed and
can be purchased by contacting the EEG sales team.
To import caption files into CCPlay, go to the CCPlay tab on the encoder’s web interface. Then, click on the
“Upload” sub-tab. Click in the box labeled “Please select your file”, and an open dialog will appear, allowing you to
navigate the drives accessible from your local computer. Click “Open” when you have selected a file, and then
press “Upload.” Once the file is uploaded, CCPlay checks it for a compatible format. You may see an error message
if your file cannot be understood by CCPlay. When successfully uploaded, your file should now appear in the
“Filelist” sub-tab, along with all other files imported into CCPlay. You can click on the file name to download the
file or view it in your browser. CCPlay also displays compact metadata for each file, including the start and end
time code values. The start time code value is especially important for syncing your file to a time code source, or
setting up the correct self-generated time code for play out.
Further documentation for CCPlay may be found at https://eegent.com/support/resources
