| 20110002663 | METHOD AND APPARATUS FOR ATTENUATING OR ELIMINATING AT LEAST A PORTION OF COLOR BURST MODIFICATIONS TO A VIDEO SIGNAL - 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. | 01-06-2011 |

| 20110135277 | Method and Apparatus for Providing in a Receiver a Copy Protection Signal That Negates a Circumvention Device and or Provides Improved Playability - A receiving device provides a “new” copy protection signal which causes resistance to certain circumvention devices and includes improved playability. The new copy protection signal causes the certain circumvention devices to pass substantially the copy protection effects to a video recorder, or causes content control effectiveness on a compliant device. That is, the new copy protection signal from the receiver causes the circumvention device to add or enhance copy protection effectiveness, which is contrary to the circumvention device's original intent of removing or reducing copy protection effectiveness. The new copy protection signal is provided by inserting or adding one or more pseudo sync pulses or one or more pseudo sync/AGC pulse pairs immediately after, one line after, or less than two and a half lines after, a vertical sync signal in at least one television line. Thus, the receiver utilizes the new copy protection signal to thwart various intended functions of the circumvention device. | 06-09-2011 |
