# Information for Teletext


This section provides information specific to Teletext input captions. It describes the fields that appear when you choose **SCC** in the **Source** field in the **Caption Selector** section of the event. For more context, see [Step 1: Identify the source captions that you want](identify-captions-in-the-input.md).

Teletext is a form of data that can contain several types of information, not just captions. Teletext can be present in SDI input, in MXF input, and in TS input, in which case it might be referred to as “DVB teletext.”. 

You can set up to handle teletext in one of the following ways:
+ If you want to extract the entire teletext input, you must set up teletext passthrough. The entire teletext can never be converted to another format. Teletext passthrough is supported only in a TS output. 
+ You can extract individual captions pages (the captions in a specific language) and convert them to another captions format.
+ You cannot extract individual captions pages (the captions in a specific language) and keep them in teletext. 

# Determining the number of captions selectors needed
Number of captions selectors
+ 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. Elemental Live will extract all the data in the teletext, even though there is not a selector to explicitly specify this action.

# Completing the fields in the Captions Selector Group
Fields in the selector group
+ **Source**: Choose **Teletext**.
+ **Page**: This field specifies the page of the desired language. Complete as follows: 
  + If you are setting up teletext passthrough captions (you are creating only one captions selector for the input captions), leave blank: the value is ignored.
  + If you are converting teletext to another format (you are creating several captions selectors, one for each language), specify the page for the desired language. If you leave this field blank, you get a validation error when you save the event.
