In this step, you will configure where and how your processed captions are delivered to a caption encoder. For a list of all steps see our Service Wizard Steps below.
Stream Type: Select 608 as your stream type.
Delivery Method: Choose how your output stream will be delivered. For 608 output, only PUSH is available.
608 PUSH
Use this option when SyncWords will push caption data directly to a caption encoder using the CEA-608 protocol. This setup is commonly used for broadcast workflows where captions need to be embedded into an SDI signal by a hardware encoder.
IMPORTANT: 608 Encoder Output is currently in preview. Please contact support for assistance with this feature.
Encoder Address: Enter the IP address (or domain) and port of the caption encoder where SyncWords should send the caption data. The encoder must be network-accessible from SyncWords. Format examples:
- IP address with port: 192.168.1.38:1999
- Domain with port: encoder.domain.com:1999
NOTE: Ensure your caption encoder is configured to listen on the specified port and that the address is network-accessible from SyncWords. Verify firewall rules allow incoming connections from SyncWords IP addresses.
Target Language: Select the language of the captions that will be delivered to the encoder. This dropdown displays all available languages configured in your Service.
Line Count: Defines how many caption lines are displayed per segment on screen. Use the numeric field or slider to set your preferred line count. The default is 3 lines.
Position (from top): Controls the vertical position of the caption text on the output video. Use the slider or numeric input to set the distance from the top of the screen where captions begin. 3 is the top of the screen, 15 is the bottom.
TIP: Keep the number of lines in mind when you set the positioning. New captions will appear on the row selected, older captions will roll up to the row above it. So, if you set 3 lines and start on row 15 you will see captions on rows 15, 14 and 13.
Disable Timeout: Enable this toggle to prevent automatic disconnection when the encoder is not sending keepalives or responses. This is useful when your caption encoder may have temporary communication delays but should maintain an active connection.
NOTE: When Disable Timeout is enabled, the connection will remain open even if the encoder becomes unresponsive. Monitor your connection status to ensure captions are being delivered successfully.
Advanced Settings: Additional configuration options are available in the Advanced Settings section. Details about these optional settings are listed below.
NEXT STEP: Once you’ve entered the required information, click "Continue" to move to Step 6: Preview where you will preview & create your Service.
Navigation Options
At the bottom of the screen, you will see the following actions:
- Cancel - Cancels the creation of your Service and exits the wizard.
- Reset - Clears all fields and settings in the Wizard so you can start over.
- Step Back - Returns to the previous step if you need to modify earlier settings.
- Continue - Moves to the next step of the wizard once the required fields are completed.
NOTE: If you click off the Wizard without Resetting or Canceling your inputs will be saved and you can return to complete the setup later.
Your Service is not created until you have been through all 6 steps and clicked the "Create Service" button.
Advanced Settings
To access the Advanced Settings, click the Advanced Settings dropdown on the page. This section provides optional configuration parameters for authentication and secure connection to your caption encoder.
Use TLS: Enable Use TLS to establish an encrypted connection to your caption encoder. TLS (Transport Layer Security) ensures that caption data transmitted between SyncWords and your encoder remains secure and protected from unauthorized access.
NOTE: When TLS is enabled, your caption encoder must be configured to accept TLS connections. Verify that your encoder supports TLS before enabling this option.
Username: Enter the caption encoder login username if your encoder requires authentication. This field is optional and should only be used if your encoder has been configured with username/password authentication.
Password: Enter the caption encoder login password if your encoder requires authentication. This field is optional and should only be used if your encoder has been configured with username/password authentication.
NOTE: Authentication credentials are securely stored and encrypted. Ensure that the username and password match the credentials configured on your caption encoder.
