Remote Captioning using an EEG iCap Encoder
What is iCap?
An EEG iCap encoder is an on-premise device that can be used to encode captions on top of a live video feed.
This device can be used to provide both remote or on-site captioning. We will discuss the setup for remote captioning in this post. For instructions regarding on-site captioning with an EEG iCap encoder, click here.
How it works
In a nutshell, an audio/video feed will be sent to the iCap encoder to be captioned. This encoder will stream the audio feed to a stenographer using the iCap software from a remote location. While listening to the audio feed, the stenographer will provide captions through their stenography machine to iCap. Once the iCap encoder receives these captions, it will overlay captions on the output video feed for the audience to see.
Network Requirements (for IT Administrators)
Please ensure that the iCap encoder will have a dedicated 3 MB/s connection.
All iCap connections are outbound initiated. After a successful handshake, iCap software can fetch the data it needs. The iCap encoder itself will not need to be accessible from outside your local network.
In strictly managed network environments, the following will ports will need to be opened.
TCP
- 9736
- 9738
- 9744
UDP
- 6900-6910
In strictly managed network environments, the following destination IPs will need to be whitelisted. IP addresses in bold are required while the others are used for load balancing.
USA (East)
- 54.235.150.124
- 54.84.222.79
- 54.85.144.87
USA (West)
- 54.193.101.112
- 52.11.108.94
- 54.193.41.201
- 44.229.71.136
- 18.236.34.114
- 13.52.203.48
Australia
- 54.206.1.214
If your network uses proxy servers, please note that SOCKS 4 is not supported. Support for SOCKS 5 is supported, however.
For more information, please review EEG’s Appnotes. The most recent document about network connectivity requirements can be found here.
Audio/Video Setup
- Connect AC power
- 120-240V
- 50-60 Hz tolerant
- Connect the video source to the Master Video In port
- Uses a BNC connector
- Supports 3D-SDI, HD-SDI, and SD-SDI
- Connect the audio source to Audio In (if applicable)
- Only required if audio is not embedded in to your video feed
- Uses XLR
- A mixing board will be required to send audio to the audience and the encoder.
- The video from the encoder with captions will be delayed by 3-4 seconds. You may need to incorporate a time delay on the mixing board.
- Connect the video output that will be displayed in your venue per your event requirements
- For open captions (where captions cannot be turned off – recommended), you should connect your video output to the Decoder Out port.
- For closed captions (where captions can be turn on and off as needed), you should connect your video output to the Master Video Out port.
- Uses a BNC connector
- Supports 3D-SDI, HD-SDI, and SD-SDI
- Connect an RJ45 network cable to the LAN port
- A DHCP IP address will work or you can set a static IP address
- Please see the network requirements in the previous section
- Power on the device
- If you own your own device, please pass along the device access code so our captioner can access the audio to provide captions.
- If you are renting a device from us, we will supply and already know the access code.
Displaying Test Captions
Being able to test your setup without having a captioner connected to the system will be important as you prepare for your event and save you money. This will ultimately tell you if everything is connected correctly and all settings are as they should be.
- Press the check mark button on the front panel of the iCap encoder
- Navigate to Utilities using the up and down arrows and press the check mark button.
- Navigate to Test Captions and press the check mark button.
- Navigate to Enable and press the check mark button.
- Navigate to On and press the check mark button.
- Exit the menu using the red ‘X’ button.
Please note that test captions will not show up if no video input feed exists.
Troubleshooting
Q: I am trying to display open captions in my venue, but captions are not visible. How can I turn on captions?
A: Press the check mark button on the front panel of the iCap encoder. Navigate to Decoder. Open the Decoder On menu and ensure that the setting is set to On.
Q: Can I change how open captions appear on screen?
A: Yes! Press the check mark button on the front panel of the iCap encoder. Navigate to Decoder. From this menu, you can chance the font size, color, and opacity to the bet fit settings for your event.
