摘要： Copy protection is provided for the now-unprotected computer monitor port of a computer 100 in two ways: (i) delaying synchronizing signals by a time variable amount and (ii) generating pulses during non-active video. Delay of the synchronizing signal is performed by selecting a fixed offset 203 and selecting either the fixed offset of the pseudorandom delay to be sent to a variable delay generator 260, which delays the horizontal synchronizing signal 201 by the selected amount. This new delayed horizontal synchronizing signal 202 is encoded by the CRT Controller 244 and is then sent to the computer monitor 164, which uses the delayed synchronizing signal 202 as encoded to produce its display in conjunction with a data signal. Thus, if these signals 202, 268 are intercepted by a VGA to TV converter 122, the converter 122 (or any downstream device) is unable to lock onto the correct frequency in order to reproduce the image properly. Horizontal pulse bars 218 may also be generated to render a signal unfit for taping purposes. The horizontal pulse bars 218 are generated to replace the portion of the video signal containing no picture information after vertical picture contraction has occurred. The amplitude of the input signal 212 is reduced, and the amplitude of the pulse bars 218 is increased to be greater than the amplitude of the input signal 212. The horizontal pulse bars 218 are then combined with the attenuated signal 214. When a VHS recorder 116 detects the amplitude of the modified signal, it lowers the amount of gain added to the signal because of the high amplitude of the added pulses. As the data content of the signal is at a much lower amplitude than the added pulses due to the attenuation, the viewable picture after taping is extremely dim and of poor quality.
摘要翻译：通过两种方式为计算机100的现在未受保护的计算机监视器端口提供复制保护：（i）将同步信号延迟时间可变量，以及（ii）在非活动视频期间产生脉冲。通过选择固定偏移203并选择待发送到可变延迟发生器260的伪随机延迟的固定偏移来执行同步信号的延迟，该可变延迟发生器260将水平同步信号201延迟所选择的量。该新的延迟水平同步信号202由CRT控制器244编码，然后被发送到计算机监视器164，计算机监视器164使用经编码的延迟同步信号202以结合数据信号产生其显示。因此，如果这些信号202,268被VGA到TV转换器122截取，则转换器122（或任何下游设备）不能锁定到正确的频率上，以便正确地再现图像。也可以产生水平脉冲条218以使信号不适于胶带目的。生成水平脉冲条218以在垂直图像收缩发生之后替换不包含图像信息的视频信号的部分。输入信号212的幅度减小，并且脉冲条218的幅度增加到大于输入信号212的幅度。然后将水平脉冲条218与衰减信号214组合。当VHS记录器 116检测到修改信号的幅度，由于相加脉冲的高幅度，它降低了添加到信号的增益量。由于信号的数据内容比由于衰减而增加的脉冲低得多的幅度，所以胶带之后的可视图像非常暗淡，质量差。
