A system retrieves content from multiple content providers to be displayed
on a Web page. The system verifies the format of the retrieved content
and rejects the retrieved content when the content format is not valid.
When the content format is valid, the retrieved content is stored in a
central database. The content is then extracted from the central database
to generate a schedule indicating particular content to be displayed at a
specific date and time. The Web server displays the appropriate content
at the specified date and time.
