Abstract:
A set top box client in an enhanced television system stores a table associating time references with events. The table is accessed to synchronize the delivery of events to an enhanced television application that is associated with an underlying video program. The enhanced television system delivers broadcast video, video-on-demand and video from a storage component such as a personal video recorder or a digital video disk player. The enhanced television system further provides an application that provides enhancements to an associated video program by overlaying a user interface, by providing overlaid graphical and/or text information or by providing additional audio information.
