EN537 Smart Encoder

Introduction

Product Description

The EN537 is an affordable caption encoder for broadcasters requiring basic caption insertion features. The unit offers Automatic Captioning services through our cloud-hosted captioning service Lexi, supports a direct serial port or TCP/IP connection, and can be also be equipped with an optional telco modem.

Please note the EN537 unit does not support using iCap to connect to captioners. However, an iCap account is required for your EN537 to communicate with Lexi over a broadband connection.

List of Features

 Connectivity to EEG’s Cloud-hosted Automatic Captioning service, Lexi.  Encoding of caption data sourced from previously encoded video sources, two RS232 serial ports,

or a dial-up modem (optional)

 Encoding of CTA-708 standard closed captions from native 708 or legacy 608 (SD) sources  Caption relocation from configurable GPI triggers  Modules for web-streaming, scoreboard connectivity, and much more.  Local logging of caption input for future reference  Relay-bypassed master video and auxiliary video paths

EN537 Smart Encoder

Encoder Setup

Quick Network Setup

To use Lexi or access further features on the encoder’s web interface, you must first select Network Settings from the front panel LCD menu and setup 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 publically 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 or any other application from the iCap Encoder.

 Program a Subnet Mask for your network  Lexi 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.

EN537 Smart Encoder

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.

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 section on page 3). The web interface is accessed by entering the IP address assigned to your encoder in your computer’s web browser. If you set the encoder up with a static IP address, the address for your web interface will be the same. 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.

EN537 Smart Encoder

Security Settings and Password Protection

To limit access to the encoder’s web interface for security purposes, you may set up a password through the front panel of your encoder via Setup > Security > Security Mode > Password. This password will be for access to the encoder’s web interface, not the encoder LCD menu. Many of the encoder’s crucial features are controlled via the encoder’s web interface.

Setting Date & Time

The Date and Time can be set by selecting Date/Time from the side menu on the web interface.

Figure 1: Date/Time Settings on the Encoder Web Interface

Updating Your Encoder

Before updating you must first download the latest update file for your encoder model from the product updates section of our website https://eegent.com/support/product_updates

Once you have downloaded the latest version for your encoder model you can apply it to the encoder either through the web interface OR the front panel USB port / LCD Menu.

 Web Interface: Select Update from the left side menu. Browse for the update file

downloaded from our website, then click Upload, and finally click Proceed.

 USB / LCD: Transfer the update file to any USB stick. Insert the memory stick into the front

panel USB port, navigate to the System Setup > Update from the LCD menu, and press enter to proceed and install the update. A message will appear on the LCD screen when the update has finished. Do not remove the memory device while the update is running.

Some updates will require a power-cycle before they take effect; in this case, the encoder will power down automatically once the update is complete.

Lexi Setup and Testing

If you did not indicate interest in Lexi at the purchase of your encoder, please contact EEG technical support at 516-293-7472 to obtain the necessary iCap and Lexi / EEG Cloud credentials. Also, be sure your EN537 is properly setup on your network prior to setting up Lexi (instructions on Page 3).

Please note the EN537 unit does not support use of iCap to connect to captioners. However, an iCap account

IS required for your EN537 to communicate with Lexi over a standard broadband connection.

1. Confirm iCap Connectivity and Know Your iCap Access Code:

 From the main page of EN537 web interface, confirm the iCap Status says Connected to

remote server. If inactive, contact EEG support for credentials.

 Your iCap Access Code can be found in the shipping documentation provided with your

Encoder. This will be used in the next step to enable Lexi to access live program audio from,

and return automatic captions to, your encoder over iCap.

Other Live Captioning Methods

Modem (Optional Add-on)

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. Once connected, the LED on the front panel of your encoder labeled “MDM” will turn green.

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 EN537 supports RS-232, RS-422, and RS-422 Sony (with RS422 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

SDI Caption Bridging

Caption bridging copies captions from the source video (AUX) to the master video output. This happens automatically when you have a captioned video input connected to the AUX connector.

Dual Encoding (Two Video Paths)

The EN537 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 produced closed-captioned video on the respective outputs. For example, if 1080i60 HD-SDI is present on the Master input and NTSC SD-SDI is present on the AUX input, the Master output will be closed-captioned 1080i60 HD-SDI and the AUX output will be closed-captioned NTSC SD-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

Figure 5: GPI Settings Found in “Main” Section of the Encoder Web Interface

EN537 Smart Encoder

Caption Uplink to Web Streaming Media Servers (Streaming Add-On)

The Streaming feature posts real-time caption data to external web services for delivering high-quality webbased closed captioning.

To determine if Streaming is installed on your unit, access your encoder’s web interface, look for an entry that says Streaming 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.

While the HTTP Streaming Uplink module is active, all closed captions through the encoder will be passed to the streaming server. These captions may be locally inserted to the video through iCap, telnet, or dial-up mechanisms (encoders only), or they may be present on the input video, and originally coded using either real-time/roll-up or offline/pop-on workflows.

Before using the Streaming feature, you will need a stream URL for posting captioning data (example: http://in.videolinq.net/caption), a stream ID or username, and a password.

Further instruction for this feature may be found at https://eegent.com/support/resources

Figure 6: Streaming Settings on the Encoder Web Interface

EN537 Smart Encoder

Cloning Live Data to Additional Encoders (Clone Add-On)

The Clone feature re-transmits all control commands and caption data to one or more additional caption encoders. The additional encoders can be connected either through RS-232, or through the Clone TCP/IP interface.

To determine if Clone is installed on your unit, access your encoder’s web interface, look for an entry that says Clone 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.

The master encoder must have the Clone port optional software installed, and then set up through clone section of the web interface. When any “Clone Server” option is enabled, the encoder will copy commands and data that are received through the dial up modem (MA), iCap, telnet, or RS-232 (P1, plus P2 if it is being used for input and not Clone output). You can also choose to copy these commands to the RS-232 port (Start RS-232).

Further documentation for this feature may be found at https://eegent.com/support/resources

EN537 Smart Encoder

XDS Insertion

Extended Data Services (XDS) is an NTSC Field 2 data channel that provides information to viewers about the program that is being aired. XDS is used to transmit FCC-mandated program ratings to allow viewer V-chip filtering. XDS is a part of the CTA-608 standard for SD broadcasts, and should be included in the 608 compatibility bytes of CTA-708 compliant HD broadcasts. XDS insertion is typically controlled through a serial

connection to an automation server and is compatible with Imagine/Harris, Snell, and EEG’s XDS Xpress solution.

XDS data packets can be loaded into the Encoder’s queue with one simple command, and be held for any specified time period. Each individual packet type can be independently set for upstream or local priority, and permanent packets can be stored in Non-Volatile Memory and inserted automatically whenever the Encoder is operating. A List of XDS commands may be found in the Command Reference section of this

manual.

EN537 Smart Encoder

Additional Features

Caption Absence Alarm

The Caption Absence Alarm feature, accessed from the Alarm section of the side menu of the encoder web interface, allows you to set alarms to automatically alert you when caption presence is not detected on the encoder for a certain amount of time. This is a useful feature for monitoring caption activity on your encoder.

Figure 8: GPI Alarm Settings on the Encoder Web Interface

Caption Input Blocking

You can block caption input to your encoder via the following non-relocation GPI functions found in the GPI Settings on your web interface. They are as follows:

 Modem Lockout: Blocks caption input from the Modem  P2 Lockout: Blocks caption input from Serial Port 2  Force Regen: Blocks caption input from Modem, P2, and iCap

Capturing Incoming VANC or 608 Data for Analysis

You can capture and save VANC data from the master video input to a USB stick for review or troubleshooting. Place a USB stick into the USB port on the front panel of your encoder and navigate to Utilites > Capture All VANC from the front panel LCD. Press ENTER to begin downloading the VANC data or CANCEL to exit. To stop capturing VANC data press any front panel key. Depending on the size/type of memory device used, there may be a momentary delay before the device is detected. If you see “Failed: Insert USB Disk”, wait a few seconds and try again. For questions about analyzing your VANC data. Please contact our support team at 516-293-7472 or support@eegent.com

Developer Features

Encoder Command Concept

Encoder Commands allow you to communicate with and control the operation of your encoder either manually or through your custom written software that contains any combination of the commands detailed in this section. All commands begin with a leading control code of <CTRL+A> or the ASCII hex code 01 for developers writing software. All commands must end with a carriage return (the <ENTER> key on a keyboard or 0D in ASCII hex). For manual entry of commands, the three following methods may be used. A Full Command Reference may be found at the end of this section.

Telnet: Commands may be entered through a telnet connection to your encoder only after you’ve enabled a telnet connection through your encoders web interface (select Telnet from the side menu)

Web Terminal: The Command Terminal is found on the web interface of your encoder (select Terminal from the side menu). This emulates the serial port interface to your encoder and allows you to enter commands directly from your encoders web interface (see figure 19).

RS-232: Commands may be entered through an RS-232 connection to your encoder. Default settings on the encoder allow entry through RS-232 right out of the box.

Figure 9: Command Terminal on the Encoder Web Interface

EN537 Smart Encoder

Startup Settings

The Startup Settings Editor enables entry of Encoder commands that will run every time the encoder starts up. Use Startup Settings whenever you want a setting to be “sticky”; settings entered through the Web Terminal or the serial port only are not sticky and will revert to defaults when the encoder is power-cycled. Startup Settings can be accessed via the encoder web interface by selecting Startup Settings from the side menu.

To use the Startup Settings editor, type any Smart Encoder command into the command box. Omit the <CTRL+A> character entirely as this character is implied at the beginning of each line. To add additional commands, press the ‘+’ button and more lines will appear.

When you have entered commands for all the settings that you want to make sticky, click Update Startup Settings. The configuration changes will take the next time the encoder starts up.
