Patent number: 10536756Abstract: A method and apparatus is disclosed which reduces or removes the effectiveness of commercial skip systems such as presently found in VCRs, PVRs, etc. which are designed to delete commercials from signal material upon playback of a previously recorded version of the signal material. In an embodiment, the effectiveness of the commercial skip system is reduced or removed by adding a flat field of selected signal level to active line portions of video lines of the signal material. Other embodiments modify the normal fade to black signal indicative of a commercial to provide a fade to non-black signal. In further embodiments, a fade to non-black signal is inserted in an overscan area of the signal picture. Still further embodiments modify audio signals or selected signals in the horizontal blanking interval which may be used in commercial skip systems to detect the presence of commercials.Type: GrantFiled: October 2, 2018Date of Patent: January 14, 2020Assignee: Rovi Solutions CorporationInventors: Ronald Quan, John O.

Patent number: 8014524Abstract: A robust technique to prevent illicit copying of video information notwithstanding the use of image scaling. A watermark is embedded into the video signal (e.g., DVD's content or other video sources) at different scales (i.e., sizes). The watermark is maintained at each scale for a predetermined time duration that is sufficient to allow the detector circuit in a DVD-recorder, DVHS recorder, DVCR, or any other digital format recorder to detect, extract, and process information contained in the watermark. At the end of the predetermined time duration, the watermark is changed to a different scale preferably on a pseudo-random basis to ensure that each one of all the scales in a predetermined scaling range is achieved a predetermined number of times. Thereby the recorder shuts off a number of times during play of the content, each time the detector circuit senses the watermark.Type: GrantFiled: June 14, 2010Date of Patent: September 6, 2011Assignee: Rovi Solutions CorporationInventor: John O. Ryan

Publication number: 20100021133Abstract: Enhancements to a video anticopying process that causes an abnormally low amplitude video signal to be recorded on an illegal copy. In one version, positive going pulses are added to the video signal. The enhancements in one version introduce into the overscan portion of the television picture, just prior to the horizontal or vertical sync signals but in active video, a negative going waveform that appears to the television receiver or videotape recorder to be a sync signal, thereby causing an early horizontal or vertical retrace. One version provides (in the right overscan portion of the picture), a checker pattern of alternating gray and black areas which causes the TV set on which the illegal copy is played to horizontally retrace earlier than normal in selected lines with a consequential horizontal shift of the picture information on those lines. This substantially degrades picture viewability.Type: ApplicationFiled: October 6, 2009Publication date: January 28, 2010Applicant: MACROVISION CORPORATIONInventors: Peter J. WONFOR, Alistair J.
