Determining the Number of Captions Selectors Needed - AWS Elemental Live

This is version 2.18 of the AWS Elemental Live documentation. This is the latest version. For prior versions, see the Previous Versions section of AWS Elemental Live and AWS Elemental Statmux Documentation.

Determining the Number of Captions Selectors Needed

  • If you are setting up teletext passthrough captions, create only one captions selector, even if you want to include multiple languages in the output. With this scenario, all languages are automatically extracted and are automatically included in the output.

  • If you are setting up teletext-to-other, create one captions selector for each language that you want to include in the output. For example, one selector to extract English teletext, and one selector to extract Swedish teletext.

  • If you are setting up teletext passthrough in some outputs and teletext-to-other in other outputs, create individual selectors for the teletext-to-other, one for each language being converted. Do not worry about a selector for the teletext passthrough output. AWS Elemental Live will extract all the data in the teletext, even though there is not a selector to explicitly specify this action.
