Abstract: A method and system for displaying updated, targeted, and/or alternately formatted advertisements to a consumer. The invention may use targeted ads in conjunction with consumer profile information to reach interested consumers. The invention may further detect stale advertisements and replace them with updated advertisements having timely information. The updated advertisements are displayed in place of the stale commercials. The invention may also display alternately formatted advertisements in place of speeded-up advertisements during a fast-forward operation on a personal video recorder. Reward-based content may also be provided, wherein the content is viewable only after one or more advertisements are viewed at normal playback speed. All of these functions are operable with a personal video recorder.

Abstract: An interactive television system is disclosed which utilizes a various distribution networks for simultaneously providing a plurality of viewers with an interactive television program comprising a plurality of signals related in time and content. Video signals are transmitted in a digital format, more than one signal being multiplexed onto a data stream on a single channel. The video signals may be compressed for efficiency. A receiver, in conjunction with a signal selector, selects a particular channel for playback, then selects a particular video signal from the data stream, and decompresses the video signal for playback. Seamless switching between video signals on different channels is provided, as well as seamless switching between video signals that have been multiplexed on the same channel. An alternative embodiment is disclosed wherein the various signals which comprise the interactive program are switched at the head end rather than at the receiver.

Abstract: A Customized Programming creation system provides the ability to transmit Customized Programming offerings to individual users based upon their known profile or their responses to contemporaneous queries. In its basic form, the invention provides for a programming transmission center to maintain a single or multiple MPEG storage server environments. Through the use of digital conversion and MPEG compression standards, a vast library of programming and other information signals can be stored on such file servers. The transmission center selects and accesses programming segments or other information from the storage servers. Through the use of splice points encoded through the MPEG process, the programming transmission center can inconspicuously splice disparate program segments together to create a single custom program stream for delivery to a single user or multiple users of the same profile.
