# Information for embedded


This section provides information specific to embedded input captions. It describes the fields that appear when you choose **Embedded** in the **Source** field in the **Caption Selector** section of the event. For more context, see the steps earlier in this section.

Read this section if the input captions you have are any of the following: embedded (EIA-608 or CEA-708), embedded\$1SCTE-20, SCTE-20\$1embedded, or SCTE-20.

**Note**  
For captions in VBI data: If you are extracting embedded captions from the input and using embedded captions in the output, and if the input includes VBI data and you want to include all that data in the output, then do not follow this procedure. Instead, see [Passing through VBI data](captions-in-vbi-data.md).

# Determining the number of captions selectors needed
Number of captions selectors

To determine the number of captions selectors you need to created in the event, follow these rules:
+ **Embedded Passthrough** – Create only one captions selector. With this scenario, all languages are automatically extracted and are automatically included in the output.
+ **Embedded In, Other Out** – If you are setting up embedded-to-other, create one captions selector for each language that you want to include in the output, to a maximum of four selectors.
+ **A combination of Embedded passthrough and Embedded conversion** – If you are setting up embedded passthrough in some outputs and embedded-to-other in other outputs, create one captions selector for each language that you want to include in the output, to a maximum of four selectors. Do not worry about a selector for the embedded passthrough output. Elemental Live will extract all the languages for that output, even though no selector exists to explicitly specify this action. 

# Completing the fields in the captions selector group
Fields in the selector group
+ **Source**: 
  + Choose embedded if the source captions are embedded (EIA-608 or CEA-708), embedded\$1SCTE-20, or SCTE-20\$1embedded.
  + Choose SCTE-20 if the source captions are SCTE-20 alone.

# Completing the fields in the CC channel number
Fields for CC channel number
+ **CC Channel number**: This field specifies the language to extract. Complete as follows: 
  + If you are setting up embedded passthrough only (you are creating only one captions selector for the input embedded captions), this field is ignored, so keep the default.
  + If you are setting up embedded-to-another-format, (you are creating several captions selectors, one for each language), enter the number of the CC instance (from the input) that holds the desired language. For example, if this captions selector is intended to hold the French captions and the French captions are in event 2, enter 2 in this field.
+ **Force 608 to 708 Upconvert**: The embedded source captions can be EIA-608 captions, CEA-708 captions, or both EIA-608 and CEA-708. You can specify how you want these captions to be handled when Elemental Live is ingesting content. The following table describes the behavior for various scenarios.    
[\[See the AWS documentation website for more details\]](http://docs.aws.amazon.com/elemental-live/latest/ug/cc-fields.html)
+ **Use SCTE-20 if Embedded Unavailable**: This field appears only if you set the **Source** to **Embedded**. If the source captions combine embedded (EIA-608 or CEA-708) and SCTE-20, you might want to set this field to **Auto**. Elemental Live will give preference to the 608/708 embedded captions but will switch to use the SCTE-20 captions when necessary. If you set this field to Off, Elemental Live will never use the SCTE-20 captions.
