Guide Database Loaders

[This is preliminary documentation and subject to change.]

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 dynamic-link libraries (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.
• Correlation between the provided data and the Guide database schema.

Updating the Guide database involves accessing the Microsoft® Jet database engine from the loader DLL. For more information on creating and working with loaders, see the following topics:
