Patent number: 8374489Abstract: In certain flat screen TV sets, such as LCD monitors, geometric errors can be induced in a video signal by positive going pulses. That is, a shift in a display is provided when one or more positive going pulse is added to the video signal following one or more sync pulse. To illustrate, AGC pulses, generally used for content control and or copy protection in the last lines of an active video field, cause a shift (horizontal displacement) in the picture for these last lines in the active field. Alternatively, turning off or attenuating such positive going pulses in the last lines of the active field, eliminates or reduces the picture shift.Type: GrantFiled: September 23, 2009Date of Patent: February 12, 2013Assignee: Rovi Technologies CorporationInventor: Ronald Quan

Patent number: 8204363Abstract: A copy protection color stripe process is defeated first by determining the location of the video lines including the color stripe process. Then some or all of the lines including the modified color bursts are modified so as to render the overall video signal recordable. The modification is accomplished in a number of ways, including phase shifting the color stripe burst into the correct phase, replacing, attenuating and or eliminating some of the color stripe bursts or at least a portion of particular color burst envelopes so that they are no longer effective, mixing the color stripe burst with color stripe signals of the correct phase so as to eliminate most or all of the phase error present or modifying the horizontal sync pulse signals immediately preceding the modified color bursts so that the modified color bursts are not detected by a VCR and hence have no effect.Type: GrantFiled: August 23, 2010Date of Patent: June 19, 2012Assignee: Rovi Solutions CorporationInventor: Ronald Quan

Patent number: 8116610Abstract: New movies from content providers are often made available on the Internet before being launched in the cinemas. Pre-released movies like DVD Videos for journalists are the main reason for this situation because some journalists seem to make these movies available to the Internet users. However, this causes significant harm to the content providers. According to the invention, the pre-releases are still DVD Videos or other conventional video formats but the playback of such encoded video signal is not possible using only a conventional DVD player or DVD player software because the playback requires additional hardware. An additional box (CP splitter box) splits the original video signal into two different video signals to be projected using two different beamers (A, B) which both are required for generating the whole video content. The beamers have different locations each with a different angle to the silver screen, and each beamer generates only a part of the video.Type: GrantFiled: November 7, 2007Date of Patent: February 14, 2012Assignee: Thomson LicensingInventor: Marco Winter

Patent number: 8059937Abstract: Generally the more effective is the copy protection provided on an optical disc, such as a DVD, the greater is the likelihood that the copy protection will adversely interfere with legitimate uses of the optical disc. It is therefore proposed to include at least one region of subversive data within the content in the data area of an optical disc, and then to prevent access to each such region of subversive data during normal playback of the disc. For a DVD, the subversive data may be incorporated within video objects and/or may be in gaps between files in the DVD_Video zone. It is arranged that there are no navigable paths to the regions of subversive data.Type: GrantFiled: September 10, 2004Date of Patent: November 15, 2011Assignee: Rovi Solutions CorporationInventors: Carmen Laura Basile, Jonny Boyd Reckless, Lee Avery, Glenn Allen Siebert, Kordian Jacek Kurowski
