Introduction

LexiLocal, EEG’s newest closed captioning product, delivers live, automatic captions on-

premises and off the cloud. LexiLocal provides elevated security and greater control over data

while achieving the same level of performance, precision, and quality as cloud-hosted

companion product Lexi.

What’s in the Box?

The LexiLocal product is a 1-RU server that can run up to 10 simultaneous channels of

captioning service.

Video closed captioning encoders and display devices are sold separately. Compatible products

include all EEG SDI Closed Caption iCap encoders models HD4XX/1490 and up, the EN537 Live

Broadcast Caption Encoder, the AV610 Live Display caption decoder, and the Alta IP software

caption encoder for MPEG-TS and SMPTE 2110.

Each device must be added to the LexiLocal server as described in this guide before they will be

recognized by server. Once connected, LexiLocal will receive encrypted audio data from the

devices and use this to provide AI-powered closed captioning.

It is also possible to use LexiLocal as a connection hub for human real-time captioners. A

captioner must have an installed copy of the iCap PC Client software (available as a free

download at https://eegent.com), and will need to configure the connection to the LexiLocal

server instead of the default public cloud iCap server hub.

Cabling and Networking Setup

The LexiLocal server will require an Ethernet connection to your local network in order to

interface with caption encoding devices, and to allow access to the web controller for initial

configuration and monitoring.

After connecting the Ethernet cable to the open connector on the rear panel of the server and

powering on the device, use the LCD front panel to configure a valid IP address on your

network.

pg. 4

It is recommended to set a static IP address for your LexiLocal server since this IP address will

also need to be entered into the caption encoding devices to establish connectivity. If you must

use DHCP, note that whenever the DHCP address changes, settings in the caption encoder(s)

must also be updated manually.

Using Front Panel Network Settings

On the front panel LCD control press the green CHECK button, also known as the “OK” button,

to enter the menu system, then navigate to “System Setup”, then “Network” and press OK to

access the network settings.

Setting a Static IP (recommended)

First, scroll down the menu and make sure the “Set Config” option is set to “Static”. Then set

the following fields manually:

IP Address: a valid IPv4 address on your local network that is not in use by another device

Subnet Mask: defines the local scope of your network subnet, for example “255.255.255.0” for

a network where the first three digits in the dotted quad are always the same.

Gateway: (optional) defines an address within the subnet owned by a device such as a router

that allows traffic out of the subnet. If all communication is intended to occur within a single

subnet then a gateway setting is not required.

DHCP

To use DHCP, go to “Set Config” in the Network menu and set “DHCP”. The LexiLocal server will

reach out through DHCP to obtain an address automatically from your router, and if successful

will show the address received.

Note that IP addresses obtained from DHCP are subject to change over time, and if the IP

assignment of your LexiLocal server changes, you will need to manually re-configure the server

field in your caption encoding devices and any iCap software used for human captioning or

system monitoring. For this reason, DHCP operation is not recommended unless your router is

configured to consistently provide the same IP assignment to the LexiLocal server. Many

pg. 5

routers can do this based on the hardware MAC address of the server, which you can obtain by

scrolling to “MAC Address” in the Network settings menu.

HTTP Management / Web Controller

Once the LexiLocal server has a valid IP address, you can log in from another computer on the

network to perform HTTP Management through the LexiLocal embedded Web Controller site.

Begin by pointing a browser to the IP address of your LexiLocal server which will then display

the login screen. The default username and password are admin/admin. You should change this

password immediately on logging in to a password meeting your organization’s security policies

and document appropriately.

Changing the HTTP Management Password

Go to the “Users” page from the left menu. Click on the “Edit” icon for the user “admin” and

change the password. Make sure to document this password properly!

You can add additional HTTP management username and password pairs from this page as

needed.

Adding Caption Encoder Devices

Your LexiLocal server can be utilized with one or more iCap compatible EEG or certified third-

party closed caption encoders. The Remote Server setting on each encoder iCap configuration

web page must be configured to point the IP address of the LexiLocal server as opposed to the

default location of the Public iCap cloud system: eegicap.com.

Note: username and password credentials are not shared between a LexiLocal system and the

public cloud iCap system. Therefore, if your caption encoder has been used on public cloud iCap

it will need to be registered in the LexiLocal User database and reconfigured with any new

credentials created in Lexi Local.

To register a new encoder with the LexiLocal server, go to the “Devices” page from the left

menu. Click “Add New” and provide a unique device username and password. Record these

carefully, you will need to copy the same strings into the iCap configuration page on the local

caption encoder.

pg. 6

LexiLocal receives program audio from the caption encoder and sends the caption transcription

to the encoder through Access Codes assigned to an encoder or a group of encoders. When

adding a new encoder, you have the option to allow LexiLocal to create an Access Code with the

same name as the device. Should you wish to create more meaningful access code names,

simply uncheck the default Create an Access Code with this as the primary Device check

box.

Configuring a Caption Encoder to Use LexiLocal

There are some differences in the menus between different EEG and third-party iCap caption

encoding products. These instructions assume an EEG HD492 encoder, but similar steps will

apply for different devices. Please consult your device manual for details or contact EEG

Support with questions.

The caption encoder will need to be able to reach the LexiLocal server on the network before

they can communicate. Usually, if the encoder and the server are on the same local subnet, this

will work without any special considerations. If the encoder and the server are not on the same

local subnet, or if you have any problems with connectivity between the encoder and server,

please consider the following factors:

1. The encoder must have a “Gateway” setting that points to a router that allows it to

communicate to the subnet the LexiLocal server lives on

2. The encoder will communicate with the server using several TCP ports that could be

blocked by some routers - make sure it is able to initiate outbound connections to the

server on TCP ports 9736, 9738, 14000, and 14002.

3. If you have a successful initial connection but then do not get audio data from the

encoder over iCap, also make sure the encoder can stream on UDP port 14010

When the networking setup is complete, navigate to the iCap settings of your caption encoder.

On the HD492, this is done by pointing a browser to the encoder’s web page, logging in if the

security settings require it, and then navigating to “iCap” in the left menu. The page you should

see is shown in the image below.

pg. 7

Follow these steps on the page:

1. Press “Stop” to turn off iCap if it is running and has been previously configured to

connect to the Public iCap cloud system.

2. Set “Company Name”: “LexiLocal”.

3. Set “Username” and “Password” to the username and password credentials already

created for this device on the LexiLocal server in section 7.

4. Set “Server Name / Remote Server” to the IP address of the LexiLocal server.

5. Press “Apply”.

6. Press “Start”.

If the configuration is successful the Status will report “Connected”, the “Server Type” will

report “Local”, and the “iCap Running” field will report “Yes”.

These settings should not need to change again on the encoder unless you change the device

credentials or the LexiLocal server IP address.

If the Status field reports:

•“Unauthorized”: Check the Company Name, Username, Password, and Server Name

settings again. This can mean that the credentials were copied wrong, or that you are

reaching the wrong iCap server.

•“Could not connect”: The encoder may not be able to reach the LexiLocal server at the

IP address given on the required TCP ports. Please consult the network tips in the

previous section.

pg. 8

•“iCap Running: No”: Try pressing the “Start” button again.

Confirming a Caption Encoder is Connected to LexiLocal

If your caption encoder is saying it is connected, you can confirm this on the LexiLocal web

controller. From the left menu, choose “Devices”, and find the caption encoder username you

just configured in the list. Under “Status” in the table, it should say “Online” if the device is

successfully connected.

Licensing for Lexi Automatic Captioning

Depending on your order and ship configuration, the Automatic Captioning component on Lexi

may or may not have an activated license. To check your license status, go in the left menu to

“Settings” and then “License”. If you have a currently activated license that is ready to use, it

will provide the number of “Days Remaining”. Typically demo licenses last for 30 days, and

production licenses are annual.

Activating a Demo

If your demo needs activation, in the “License” page, you should have a unique number in the

License# field identifying your product, but the “Status” reports “Not Licensed”. You may also

see a Notification in the lower left of the screen saying, “Demo license needs activation or

license purge.”

In the License page, find the section that says, “GET ACTIVATION CERTIFICATE” and click the

ACTIVATE LICENSE button. A menu will appear requesting that you leave the LexiLocal box

running continuously during the activation process. If you can do this, click OK.

The process of generating your activation certificate may take about 4 minutes. When it

completes, a file called “activation_certificate_xxxxxxx.json” should download in your browser

to your default Downloads location. Locate this file and email it to suppor[email protected] for

license activation service. EEG Support will service requests as quickly as possible, but please

allow a turnaround time of up to 48 hours.

When your license certificate from EEG Support is returned via email, copy the file to a drive

that will be accessible to the PC that you use to access the LexiLocal web controller. Browse to

the “License” page and in “APPLY LICENSE CERTIFICATE” click the “CHOOSE FILE” button to

select the license file provided to you by EEG. Next, press the green “UPLOAD” button. You

should see a success message, and now your product is ready to use.

pg. 9

Upgrading or Renewing a License

To upgrade your demo to a production license, or to renew an expiring production license,

contact EEG Sales for a quote and payment instructions. The technical process for entering your

license will follow the Activating a Demo process described above.

Beginning an Automatic Captioning Session

Once a caption encoder is connected to LexiLocal and the Automatic Captioning component is

licensed, you will be able to begin an automatic captioning job.

A captioning job will target a specific “Access Code.” An access code is a group of one or more

caption encoders that will receive matching caption data whenever their code is used. Most

commonly an access code will contain only one encoder (the “Primary Device”). However, there

are many use cases for adding “Secondary Devices”, such as backup or archival video feeds, or

feeds with the same audio programming but different graphics or video resolution.

If you opted to create a default access code when adding your device, please skip to the

Creating a Lexi Instance section.

Creating a New Access Code

In the LexiLocal web controller, choose “Access Codes” from the left menu and click the “Add

New” button. Then:

1. Create a unique name

2. For single language captioning, leave “CC Service” set to S1. If you plan to encode

multiple languages of captioning on the same video, you can create additional access

codes that target the same encoder using S2 through S6. (These codes refer to the CTA-

708 standard codes for languages, however different encoder devices may use formats

other than 708 to represent the different track.)

3. For “Primary Device”, select the encoder that will provide the audio track for

transcription and will receive the captions.

4. If desired, add one or more “Secondary Devices” so that additional encoders receive the

same captions. The Secondary Devices will also act as a fallback to provide audio if the

Primary Device disconnects from LexiLocal.

5. Click SUBMIT.

pg. 10

Creating a Lexi Instance

A Lexi “Instance” is a preset that defines the parameters for an automatic captioning job to be

performed by the LexiLocal server. The instance can be turned on and off as needed through

the web controller or HTTP API. You can create any number of instances you wish for different

use cases, but your Lexi Automatic Captioning license will determine how many different Lexi

jobs you can run simultaneously on the server.

To create a new Lexi instance, go to “Lexi” in the LexiLocal web controller main menu. Click Add

New. Then:

1. Provide a name for the Lexi instance you will remember.

2. Choose an access code that include the caption encoders you wish to send data to. You

can select the access code from the list previously created on this LexiLocal server as

described in the previous section.

3. Select a “Topic Model” to use a previously created list of custom vocabulary when

performing automatic captioning. See the next section for information about working

with Topic Models.

4. Click the “Advanced Options” checkbox to configure the caption language service as well

as the caption display parameters such as base row, number of rows, column indent,

and “All Caps”. You may set an inactivity timeout so that the Lexi job will stop after

dialog is not detected in your audio stream for the selected amount of time. The default

value is 10 minutes. Lexi instances that are stopped in this way will need to be manually

restarted later.

5. Click SUBMIT.

Once a Lexi instance is created, you can use the On/Off toggle switch in the table under “State”

to begin captioning. If your encoder is in communication with LexiLocal and sending an audio

stream successfully, you should now begin to see captioning on its output!

Topic Models

Topic Models can be used to enter lists of custom vocabulary to aid the speech recognition

system in learning new words and phrases that are unique to your programming, organization,

or topic domain.

You may create as many Topic Models as you and choose the one that is most appropriate for a

specific channel or event when configuring the Lexi instance (see previous section).
