摘要： Enhancements to a video anticopying process that causes an abnormally low amplitude video signal to be recorded on an illegal copy. 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： A standard video signal is modified such that the modified video can be displayed in a normal fashion on a standard monitor device, yet copies made of the modified video signal by videotape recorders will reproduce a video signal containing disturbances which cause a generally unviewable display on a standard television or other video monitor device. The video signal is converted from a standard frame rate to a predetermined, non-standard frame rate video signal utilizing a videotape recorder modified to record at a non-standard speed.

摘要： A standard video signal is modified such that the modified video can be displayed in a normal fashion on a standard monitor device, yet copies made of the modified video signal by videotape recorders will reproduce a video signal containing disturbances which cause a generally unviewable display on a standard television or other video monitor device. The video signal is converted from a standard frame rate to a predetermined, non-standard frame rate video signal utilizing a videotape recorder modified to record at a non-standard speed. A burst interfering signal also can be added. A method of permitting a normal picture to be displayed from the modified video signal includes adding delay devices to a VCR or video monitor to respond to the non-standard frame rate and filtering or replacing the burst interfering signal.

摘要： Video signal lines are added to or omitted from the ends of individual fields of a video signal to produce a modified video signal whose field length varies at a slow rate. The modified video signal can be broadcast and received by conventional television equipment, normal television reception and viewing being not noticeably affected by the variable field length. However, recording of the modified video signal is inhibited because the field length is not constant. The modified video signal is produced by directly modifying the scanning of televising equipment, or by storing the lines of the video signal in a store and reading them in a controlled manner therefrom. A decoder, for producing a constant field length video signal from the modified video signal, is also disclosed.
摘要翻译：视频信号线被添加到视频信号的各个字段的末端或从其中省略，以产生其长度以较慢速率变化的修改的视频信号。修改的视频信号可以由传统的电视设备广播和接收，正常的电视接收和观看不会受到可变场长度的明显影响。然而，由于场长度不恒定，所以修改后的视频信号的记录被禁止。经修改的视频信号通过直接修改电视设备的扫描，或通过将视频信号的行存储在存储器中并以受控的方式读取来产生。还公开了一种用于从修改的视频信号产生恒定视场长度视频信号的解码器。

摘要： A method and apparatus to inhibit the piracy of motion pictures in theaters by taking advantage of the frame rate discrepancies between film (or digital) display and video camcorders. By alternating specific image display intervals and, shuttering cadences, or with digital video projectors commanding a similar modified display via the digital projector's blanking and display capabilities, so that the projected images occur in a random and/or phase shifted manner, objectionable distortions are produced in an illicitly captured video image, while being invisible to theatrical viewers. In addition, various serrated, slit, multi-quadrant or spotted patterns may be used on mechanical shutters, or simulated on digital displays, to further degrade the quality of illicitly captured video by pirates in theaters.

摘要： The present invention alters a signal slightly after the decoding step so that the quantization loss is made recurring while not obvious to a human viewer of the decoded signal. The slightly altered signal, when re-encoded, is degraded enough to be annoying, without the measures being perceived in the first decoded signal. The present invention can be applied to a decoded digital signal if sufficient register space is available or to an analog signal after AD conversion.

摘要： Novel systems and methods for preventing piracy of motion picture images by recording the images as they are displayed on a movie screen, using a camcorder as a recording device. Two alternative anti-piracy systems and methods are described. The first method is to vary the frame rate of the displayed motion picture images in a random fashion, thus preventing the camcorder from synchronizing its internal frame rate with that of the displayed motion picture image. The second method is to transmit pulsed energy with frequencies in the frequencies of visible light, such as red light in a manner with sufficient transmitted power or frequency to degrade the quality of the recorded image by the recording device. The result is significantly degraded quality of the recorded ima ges. The two embodiments can be used alone or in combination.

摘要： A method and projection system for distorting a recording of a plurality of projected frames is disclosed, comprising a high frame rate display configured to impose a modulation on the projected frames at a frequency that is above the critical fusion frequency of the human visual system, wherein the modulation is of one of shutter width relative to shutter spacing, brightness, frame period, and pseudo-rastering. The high frame rate display may be a tonal display. The projection system may further include hardware for producing low frame rate imagery; an input buffer operatively coupled to said hardware for receiving one of a serial bit stream or blocks of data so as to store at least a predetermined portion of a frame; and a sub-frame generator operatively coupled to said input buffer and to said high frame rate tonal display for applying mathematical modulation techniques to said at least a predetermined portion of a frame.
