Overview of Program Guide Services
The Program Guide provided by Broadcast Architecture displays television and supports data services that broadcast television-schedule information to the user. In addition, users can use the Program Guide to tune to a specific show in the schedule and set reminders to watch shows.
The Program Guide maintains current information about program schedules in a Microsoft® Jet database, Tss.mdb. Because broadcast schedule information constantly changes, this Guide database must acquire and update broadcast data on a regular basis. This acquisition and update is done using a loader application.
The following topics examine Program Guide services:
- Guide Data describes the various problems involved in integrating Program Guide information from multiple networks. This section also discusses how dynamic-link libraries (DLLs) can be used to load data into the Guide database.
- Guide Database Loaders outlines the tasks that any loader application for the Guide database must complete to operate successfully. This section also includes details about how to write a custom loader application.
- Loadstub discusses how to work with the Loadstub component, Loadstub.exe, which starts a loader DLL.
- Guide Data Objects covers a set of objects that applications use to retrieve or set values in the Guide database.
- Guide Database Schema provides a detailed description of the tables and fields in the Guide database.
- Program Guide Registry Values defines the values created in the operating-system registry for tuning spaces and their associated loader applications.
