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. |
