ISCTE_EAS Interface

This topic applies to Windows Vista.

The ISCTE_EAS interface enables the client to get data from an ATSC emergency alert message (EAS) table. The IAtscPsipParser::GetEAS method returns a pointer to this interface.

For more information about EAS tables, see ANSI-J-STD-042-2002, Emergency Alert Message for Cable.
