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.

In addition to the methods inherited from IUnknown, the ICAT interface exposes 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.
RegisterForWhenCurrent Registers the client to be notified when the table becomes current.
