摘要： An apparatus and method for applying anti-copy protection to a raster-scanned video signal are described. A square waveform 52 is added to the vertical synchronization pulses 50 of the video signal. The effect of the waveform is not apparent until it has been recorded by a video cassette recorder. The anti-copy protected video signal can therefore be viewed normally on a display device at or near to the picture quality intended by the originator of the video signal, but once recorded, exhibits a reduction in picture quality which makes the video signal quite unattractive to view.

摘要： 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.
摘要翻译：接收装置提供“新的”复制保护信号，其产生对某些规避设备的阻力并且包括改进的可播放性。新的复制保护信号使某些规避设备基本上将复制保护效果传递到录像机，或在兼容设备上引起内容控制的有效性。也就是说，来自接收器的新的复制保护信号导致规避设备添加或增强了防拷贝保护的有效性，这与规避设备的删除或降低防拷贝效能的原始意图相违背。新的复制保护信号是通过在垂直同步信号中插入或添加一个或多个伪同步脉冲或一个或多个伪同步/ AGC脉冲对，紧接在之后的一行之后或之后的两行半行之后的垂直同步信号至少有一条电视线。因此，接收机利用新的复制保护信号来挫败规避装置的各种预定功能。

摘要： Method and apparatus for controlling subsequent permitted use, such as storage, of video on a digital storage device such as a personal video recorder (PVR). An analog video signal is provided with at least one modification to its video characteristics, for instance in the horizontal blanking interval and vertical blanking intervals, which is of the type having the capacity to inhibit making an acceptable analog video recording of the analog video signal. Examples of these modifications are the well known pseudo-sync (automatic gain control), color stripe (color burst modifications), and added back porch pulses. The pattern of presence or absence or nature of the modifications also serves as a code to carry information as to the subsequent permitted use in the digital realm, such as whether the accompanying content of the video signal is allowed to be digitally recorded in digital form in a compatible PVR personal video recorder, and if it is allowed to be recorded, the length of time that the recording is allowed to persist, for instance one day, one week, one month. Hence the modifications to the analog video signal have a dual use in both inhibiting recording in the analog realm and carrying information across the analog video interface so as to control storage (copying) or other use of the video in the digital realm.
摘要翻译：用于控制诸如个人录像机（PVR）的数字存储设备上的视频的后续允许使用（诸如存储）的方法和装置。模拟视频信号具有至少一个对其视频特性的修改，例如在水平消隐间隔和垂直消隐间隔中，其具有禁止对模拟视频信号进行可接受的模拟视频记录的能力。这些修改的实例是众所周知的伪同步（自动增益控制），彩色条纹（彩色脉冲串修改）和添加的后沿脉冲。存在或不存在或者修改的性质的模式还用作携带关于在数字领域中随后允许使用的信息的代码，诸如视频信号的伴随内容是否被允许以数字形式数字地记录一个兼容的PVR个人录像机，如果允许记录，允许记录的持续时间长短，例如一天，一周，一个月。因此，对模拟视频信号的修改在禁止模拟领域的记录和跨模拟视频接口传送信息的同时具有双重用途，以便控制数字领域中的视频的存储（复制）或其他使用。

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： A television (TV) monitor or receiver normally displays only the active portion of a video signal, and generally the HBI (horizontal blanking interval) and/or the VBI (vertical blanking interval) are not displayed. In some TV displays however, there is provision to display at least a portion of a blanking interval (overscan area). In some displays (such as monitors for professional use) the VBI is displayed as a way to allow the user to monitor test, command, and/or reference signals. If there are added pulses such as the well known copy protection signals present in blanking intervals of the video signal that cause a horizontal (or vertical) timing or recovery circuit to result in erroneous timing, then viewing is impaired of at least one blanking interval for the TV display. For example, if added copy protection pulses in the VBI region cause the horizontal phase lock loop circuit in a TV display to cause a mistiming, then viewing of signals in the VBI (overscan area) will be impaired. Such signals may include test signals and/or sync signals. A method and apparatus disclosed here improve or correct timing in TV display circuits to allow better viewing of the blanking intervals. One such method is to reposition and/or to remove or modify at least one added or other pulse in the VBI and/or HBI.

摘要： To prevent the user from moving a content on a bound recording medium to another storage medium more than the maximum number of times permitted by its copyright holder.A recorder includes: a bound recording section for bound-recording at least one data file and at least one management information file for a content; a control section for giving an instruction to move the content to a storage medium; and a drive for recording the content's data on the storage medium. The management information file includes access information for accessing the data file. In response to the instruction to move, the bound recording section reads the data file of the content in accordance with the access information and outputs the content's data, the drive records the content's data on the storage medium, and the control section makes the access information unavailable.
