<p>An interactive television system is provided in which a user can use an interactive television application to establish time-based settings. The user may set television program reminders, advance-order pay-per-view programs, schedule programs for recording, and establish parental controls to prevent television viewing during certain times on certain channels. The interactive television application may be used to support video recorder functions such as personal video recorder functions implemented locally on the user's set-top box or other equipment and network-based video recorder functions implemented using servers at cable television headends and other network locations. The interactive television application may also be used to deliver video-on-demand content. When the user requests that video be delivered, conflicts may arise between the requested video delivery and the previously-established time-based settings. The interactive television application may provide the user with on-screen options that allow the user to select how to resolve these conflicts.</p> |
