摘要： A method and apparatus is provided for generating or providing any of various types of modifications purposely made to generally known signals, waveforms, conditions, functions, etc. The modifications are sensed, read, detected or interpreted to provide a content control command indicative of the difference between the original signal, waveform, condition, functions, etc., and the modified signal, waveform, condition, function, etc. The content control command may be used to provide content control for a content control system, which in turn may provide control of a selected compliant device.

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： Copy protection normally included in a video signal to prevent unauthorized copying is dynamically modified, by changing an attribute of the copy protection to be added to or present in the video signal. The copy protection can include any signal that affects playability of an attenuated video signal, for example, by triggering an early or late horizontal or vertical retrace (such as caused by sync narrowing or the checker signals described in U.S. Patent 5,583,936). The attribute change (53) is related to scene content carried by the video signal, so that bright and dark scenes carry different copy protection. The attribute being changed can be, for example a checker's low level that is reduced to below the blanking level when the scene content is darker than normal, and increased to above the blanking level when the scene content is brighter than normal. Alternatively, the attribute being changed can be width of a synchronization pulse normally present in the video signal. The brightness of a scene carried by the video signal can be measured directly (52), or alternatively as the change in attenuation in the synchronization pulse received at the input of a sync separator of a typical VCR or TV set.

摘要翻译：复制保护通常包含在视频信号中以防止未经授权的复制动态修改，通过改变复制保护的属性添加到或存在于视频信号中。复制保护可以包括任何影响衰减视频信号的可播放性的信号，例如，通过触发早期或晚期水平或垂直回扫（例如由同步缩小或美国专利5,583,936中描述的检查器信号引起）。属性改变（53）与视频信号携带的场景内容有关，使得明亮和黑暗的场景具有不同的复制保护。被改变的属性可以是，例如，当场景内容比正常情况更暗时，检查者的低电平降低到消隐电平以下，并且当场景内容比正常情况更亮时，增加到消隐电平以上。或者，被改变的属性可以是通常存在于视频信号中的同步脉冲的宽度。视频信号携带的场景的亮度可以直接测量（52），或者作为在典型VCR或电视机的同步分离器的输入端接收到的同步脉冲中的衰减变化来测量。

摘要： Digital content is mastered as a combination of encrypted data and data processing operations that enable use in approved playback environments. Player devices having a processing environment compatible with the content's data processing operations are able to decrypt and play the content. Players can also provide content with basic functions, such as loading data from media, performing network communications, determining playback environment configuration, controlling decryption/playback, and/or performing cryptographic operations using the player's keys. These functions allow the content to implement and enforce its own security policies. If pirates compromise individual players of content titles, new content can be mastered with new security features that block the old attacks. A selective decryption capability can also be provided, enabling on-the-fly watermark insertion so that attacks can be traced back to a particular player. Features to enable migration from legacy formats are also provided.

摘要： Techniques for watermarking and distributing are provided. Content is broken into frames, each frame includes a watermark. Resources request the content and each frame of each resource's acquired version of the content includes a watermark. The frames of each resource's acquired version of the content form unique watermark sequences or unique keys. Each watermark sequence or key is uniquely associated with a particular resource. Each resource is also provided one or more delivery plans for acquiring that resource's uniquely watermark and sequenced version of the content over the network.

摘要： An application media drive, and media are configured so as to cooperate with one another to provide secure access and copying of protected content on the media. The application cooperates with the media drive to identify the media as a cooperating component, and in the process, also identifies the media drive as a cooperating component. The media includes information facilitating such identifying activity, such as a fingerprint indicating the copy protection method used to protect the content. Also included on the media is a guard module that authenticates the application as a cooperating component, establishes secure channel respectively with the application and the media drive for communicating secret information, installs licences included on the media, and only allows access to the protected content if the media is an original copy. The application then manages usage and/or copying of the protected content according to the installed licenses.

摘要： The present invention relates to a method and a system for managing a data object so as to comply with predetermined conditions for usage of the data object. To control the usage of the data object, a set of control data, defining usages of the data object which comply with the predetermined conditions, is created for the data object. The data object is concatenated with the user set of control data, encrypted and transferred to the user. When the user wants to use the data object, a special user program checks whether the usage complies with the control data. If so, the usage is enabled. Otherwise it is disabled.

摘要： An instrumentation system estimates characteristics of a decentralized network, such as: the size, growth rate, and growth acceleration of the network; the number of instances, the rate of propagation, and the acceleration of propagation of a file in the network; and the search and download activities, in the aggregate and for particular files, in the network. A data center in the instrumentation system performs a set of interrelated methods for inferring these and other characteristics of the network. For estimating some characteristics, it identifies and uses a subset of the network, and uses information from the subset to infer or obtain information of the entire network. For estimating other characteristics, it deploys software agents to masquerade as nodes in the network.
