Guide Database Loaders

For each tuning space, a corresponding Guide database loader exists. A database loader typically:

• Accesses the Guide database.
• Acquires Program Guide data from a specified source.
• Maps data from the Program Guide source to the appropriate fields in the Guide database.
• Updates the database with the new data.

Guide database loaders are DLLs. The specifics of creating a Guide database loader vary depending on:

• Tuning spaces supported.
• Source of the Program Guide data (for example, downloaded from the Internet versus broadcast live).
• Format of the Program Guide data.
• How the Program Guide data fits into the tables and fields within the Guide database schema.

To update the Guide database, your loader DLL accesses the Microsoft® Jet database engine to edit the Guide database. For more information on creating and working with loaders, see the following sections:
