<p>A data management and distribution system for an electronic program guide ("EPG") for television programs comprising an automated data collection subsystem, a manual entry and correction subsystem, a database validation subsystem, an edition generation subsystem, a configuration subsystem, and a status and control subsystem. The system may further comprise a feed generation subsystem if one or more of the EPG providers supported by the EP G distributor requires a live feed of data. The automated data collection subsystem collects EPG data from multiple sources in various formats, filter s the data based on the needs of the EPG providers supported, and places the data in a centralized database in a form suitable to support the different environmental contexts of the EPG providers. The manual entry and correction subsytem permits the EPG distributor to make manual corrections, additions, and deletions to the data stored in the database. The database validation subsystem verifies the data stored in the database in accordance with designated verification options. The edition generation subsystem generates the different editions of the EPG for the different EPG providers supported by the EPG distributor. The configuration subsystem receives information from t he various EPG providers and furnishesthis information to the other subsystems which utilize the information in performing their respective tasks. The stat us and control subsystem monitors the operation of the data management and distribution system as a whole. The various feeds and editions are then transmitted to the EPG providers by, e.g., satellite, wire, cable, etc. The EPG providers receive the feeds and editions and use them provide one or bot h of a dedicated channel EPG and interactive EPG to subscribers.</p> |
