Abstract: A Personal TV System receives a plurality of video segments constituting a TV program and information describing each segment, and controls the display of the segments to a viewer in accordance with preferences of the viewer and with the description of each segment. Segments may be omitted or replaced with substitute segments. The viewer may review his preferences and edit or replace them. In a multi-viewer household, the system may prompt a viewer to confirm her preferences. A TV program may contain interactive segments, and when the viewer chooses to interact with a particular segment, the system automatically stores all subsequently received segments for later viewing while the viewer interacts with the selected segment. The system may present TV program choices to the viewer selected and arranged in accordance with her preferences.

Abstract: An editing system has a video store for storing a video sequence and a text store for storing a sequence of text associated with the video sequence. Displays and are provided for displaying the video and the text on the text display. The current text position is indicated by a cursor 10 or by another marker. The frames of the video sequence have time codes associated therewith. Corresponding time codes are associated with the text using the time codes and the rate n of reading words:— The current position in the text is controllable in dependence on the time code of the video frames; and the video frame currently displayed is controllable in dependence upon the current position in the text.

Abstract: A sequence of video frames is assembled from video clips. The frames have time codes associated therewith. It is desired to match sections of the text (T1, T2) to corresponding sections (V1, V2) of the video sequence. Time codes (TCx, TCx+1) corresponding to the time codes of the video frames are entered into the text. A rate n of reading the words of the text is defined. The extent W of the text which matches an associated section of the video is calculated as W=(TCx+1−Tcx).n. On a text display, the extent W of the text which matches the video section is indicated by highlighting or in other ways. More text than matches a video section may be provided. The excess text or overflow text is distinguished on the display by e.g. color from the active text which matches the video section.

Abstract: The method and system for TV user profile data prediction and modeling allows accurate and narrowly focused behavioral clustering. A client-side system classifies television consumers into representative user profiles. The profiles target individual user advertising and program preference category groups. A contextual behavioral profiling system determines the user's monitor behavior and content preferences, and the system may be continually updated with user information. A behavioral model database is queried by various system modules. The programming, including targeted advertising for television and interactive television is based on the profile data prediction, modeling and preference determination. The system is enabled to present a complete program sequence to the viewer based on the preference determination and stored programming.

Abstract: A method for displaying a TV program to a viewer comprising receiving a plurality of TV programs, allowing the viewer to select one of the plurality of received TV programs for viewing, and responding to the viewer selection by displaying the viewer selected program and displaying additional programs in accordance with previously specified display criteria, the additional programs selected in accordance with the previously determined viewing preferences of the viewer. The display criteria are specified by the head-end operator and may include display schedule criteria, selected program criteria, and previously determined viewing preferences criteria. The additional programs may include advertisements.

Abstract: A method for displaying a TV program to a viewer, comprising receiving a plurality of TV programs, allowing the viewer to select one of the plurality of received TV programs for viewing, and responding to the viewer selection by controlling the programming displayed to the viewer in accordance with the viewer selection and with previously determined viewing preferences of the viewer. Controlling the programming displayed to the viewer may include displaying the viewer selected program and additional programs selected in accordance with the previously determined viewing preferences of the viewer. The additional programs may include advertisements.
