摘要： Enhancements to a video anticopying process that causes an abnormally low amplitude video signal to be recorded on a illegal copy. The enhancement in one version include 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. In another version, selected horizontal sync pulses are narrowed, causing irregular vertical retraces. In another version, post-pseudo sync pulses that have a minimum level above the minimum level of sync pulses are added to enhance anti-copy effectiveness. The post pseudo-sync pulses may be amplitude modulated.

摘要： 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. In another version a gray pattern at the bottom overscan portion of the picture causes vertical picture instability. In another version selected horizontal sync signals are narrowed, causing irregular vertical retraces. Also provided is apparatus for removing or attenuating these enhancements from the video signal, to allow copying.

摘要： In record or content control management systems, various selected reference, record control, copy protection or control information signals, or other signifiers, are used to identify control signals, for example, bits, to provide control of subsequent use of data, audio and video signals in the analog and digital domain. Method and apparatus are disclosed for modifying the effects of a content control system as well as for modifying an effect of a copy protection signal. To this end, the reference, record control, copy protection signals, or other control information signals, e.g., content control signals, may be modified to cause an erroneous or unintended reading subsequently of the reference or control signals which in turn correspondingly alters the control command of the record or content control system. Further, where a copy protection signal is being used as a control signal, a modification may be made to the copy protection signal to alter the subsequently generated control command while still maintaining copy protection effects in the analog domain and allowing recording in the digital domain. Also, included are unique methods for providing content control.

摘要： A modified Colorstripe™ copy protection process utilizes a basic anti-copy protection (ACP) signal that causes attenuation of a video signal, wherein, in one embodiment, the process modifies (lowers) the level of a front porch portion and adds an incorrect color signal (color burst) in the region of the sync tip. When an illegal copy is made, a pre-blanked end of line portion causes a TV set to trigger the color burst sample pulse ahead of time and cause the incorrect color signal in the sync tip region to be sampled. Thus, since the sync tip region has incorrect color phase or frequency, the resulting illegal copy will have enhanced color distortions. In other embodiments, other portions of the horizontal blanking interval are lowered in level and incorrect color bursts are added to a portion or portions of the back porch and/or a portion of the front porch. A further embodiment employs lowering a back porch portion above a sync tip level near the beginning of a video line to form a pseudo sync/AGC pulse pair. The various embodiments of the process may include an adaptable process, as well as several alternative ACP signals for use in combination with the process.

摘要： A method and apparatus for defeating copy protection signals in a video signal, and also for providing copy protection signals for a video signal, is disclosed. The defeat technique generally utilizes a particular pulse position shifting, modulation, etc., of AGC, normal sync and/or pseudo sync pulses to increase the separation between the pulses. Various embodiments are disclosed including selective shifting of the relative positions of either the sync/pseudo sync or AGC pulses, trimming portions of the sync/pseudo sync and/or the AGC pulses and narrowing of either the sync/pseudo sync and/or the AGC pulses, all to provide the selective position separation between the sync/pseudo sync and AGC pulses. The copy protection technique includes various embodiments for dynamically varying the sync/pseudo sync and AGC pulse separation by applying a modulation of the above position shifting, trimming and/or narrowing techniques over selected time periods to cycle from the copy protection condition to the copy protection defeat condition, back to the copy protection condition.

摘要： Video signals are scrambled by position modulating or switching between two types of modified horizontal sync pulses. These modified horizontal pulses are modulated or switched at a rate that causes a non-interlaced tearing pattern when viewed by an unauthorized viewer, whereby greater concealment is achieved by the invention when compared to the prior art. The modified scrambling process also is adapted to achieve lower tuner AGC artifacts. With added fake vertical sync signals and strategic use of double or multiple horizontal sync pulses per TV line, modern TV sets using count down circuits are also affected vertically to enhance the concealment effects.

摘要： In the known color stripe process for preventing recording of video signals, the color burst present on each line of active video is modified so that any subsequent video tape recording of the video signal shows variations in the color fidelity that appear as undesirable bands or stripes of color error. This color stripe process is defeated first by determining the location of the video lines including the color stripe process, either by prior experimentation or by on-line detection. 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 some of the color stripe bursts or a portion of particular color stripe bursts so that they are no longer effective, and 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. The modified color bursts are defeated, in other versions, by 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.

摘要： In a known copy protection process for preventing recording of video signals, pseudo sync and AGC pulses are present on predetermined lines within the blanking intervals of the video signal so that any subsequent video tape recording of the video signal shows a picture of very low entertainment quality. This copy protection process is defeated first by determining the location of the video lines containing the copy protection using the color burst signal or chroma in the horizontal blanking interval to determine on-line detection. Then some or all of the lines including copy protection signals are modified so as to render the overall video signal recordable. The modification is accomplished in a number of ways, including gain shifting portions of the video signal, level shifting portions of the video signal, bandwidth limiting certain portions of the video signal or replacing certain portions of the video signal with other video elements.
