IATSC_MGT Interface
This topic applies to Update Rollup 2 for Microsoft Windows XP Media Center Edition 2005 and later.
The IATSC_MGT interface enables the client to get data from a master guide table (MGT). The MGT describes the program guide information and service information that is delivered in a transport stream, including the table types, the packet identifiers, and the version numbers. The IAtscPsipParser::GetMGT method returns a pointer to this interface.
The MGT may contain one or more table-wide descriptors. In addition, each record in the MGT may have one or more descriptors. To get the table-wide descriptors, use the GetTableDescriptorByIndex method or the GetTableDescriptorByTag method. To get the record descriptors, use the GetRecordDescriptorByIndex method or the GetRecordDescriptorByTag method.
