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.
