ICAT Interface

This topic applies to Update Rollup 2 for Microsoft Windows XP Media Center Edition 2005 and later.

The ICAT interface enables the client to get data from a conditional access table (CAT). The IAtscPsipParser::GetCAT method returns a pointer to this interface.

Methods

The ICAT interface inherits the methods of the IUnknown interface.

In addition, ICAT defines the following methods.

Method	Description
ConvertNextToCurrent	Converts a next table to a current table.
GetCountOfTableDescriptors	Returns the number of descriptors in the CAT.
GetNextTable	Retrieves the next table that follows the current table.
GetTableDescriptorByIndex	Retrieves a table descriptor for the CAT.
GetTableDescriptorByTag	Searches the CAT for a descriptor with the specified descriptor tag.
GetVersionNumber	Returns the version number for the CAT.
Initialize	Initializes the object.
RegisterForNextTable	Registers the client to be notified when a next table arrives that will replace the current table.
