IATSC_ETT Interface
This topic applies to Update Rollup 2 for Microsoft Windows XP Media Center Edition 2005 and later.
The IATSC_ETT interface enables the client to get information from an extended text table (ETT). The IAtscPsipParser::GetETT method returns a pointer to this interface.
An ETT provides text descriptions for events or virtual channels. Each ETT contains a single extended text message (ETM) stream. The ETM stream might contain descriptions for multiple languages.
In addition to the methods inherited from IUnknown, the IATSC_ETT interface exposes the following methods.
| Method | Description |
| GetEtmId | Returns the ETM identifier. |
| GetExtendedMessageText | Returns the message text. |
| GetProtocolVersion | Returns the protocol version of the table. |
| GetVersionNumber | Returns the version number for the ETT. |
| Initialize | Initializes the object. |
