| Platform SDK: Broadcast Architecture |
For any given broadcast service, one or more sources may provide Program Guide data. Because of the number of sources and formats for Program Guide data, it would be unwieldy for the Program Guide to directly receive Program Guide data. There are simply too many variations.
To address this problem, Broadcast Architecture uses database loader applications. A loader application can be written for any given data source. Each tuning space has an associated Guide database loader. For more information on Guide database loaders, see Guide Database Loaders.
The following illustration shows the relationship between a database loader and the Guide database.
