    • Provided are a method and a system for designing an embedded system using a design process for building a general-purpose computer. Specifically, the embedded system design includes adding and removing add-on cards as needed during the development of the embedded system design. The add-on cards are easily obtainable and connect to a circuit board of the embedded system by selecting lines originating from the circuit board. The lines not selected are passed on to other add-on cards connected to previously connected add-on cards. After all the lines from the circuit board are either selected to connect to logic of the add-on cards or remain unselected, information regarding the add-on cards are used to generate a configuration image. The configuration image is transmitted to a programmable processor of the circuit board to enable communication on the selected lines, thus permitting the embedded system to function.
    • 提供了一种使用设计过程来构建通用计算机来设计嵌入式系统的方法和系统。 具体来说,嵌入式系统设计包括在嵌入式系统设计开发过程中根据需要添加和删除附加卡。 通过选择源自电路板的线路,可以轻松获得附加卡并连接到嵌入式系统的电路板。 未选择的行传递到连接到先前连接的附加卡上的其他附加卡。 在选择所有来自电路板的线路以连接到附加卡的逻辑或保持未选择之后,关于附加卡的信息用于生成配置图像。 将配置图像发送到电路板的可编程处理器,以使得能够在所选择的线路上进行通信,从而允许嵌入式系统起作用。

    • 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.
    • 对视频防篡改过程的增强,导致异常低幅度的视频信号被记录在非法拷贝上。 一个版本的增强功能在电视图像的过扫描部分之前,在水平或垂直同步信号之前,但是在活动视频中,将电视接收机或录像带录像机呈现为同步信号的负向波形,从而导致 早期水平或垂直回溯。 一个版本提供(在图片的右侧过扫描部分),交替的灰色和黑色区域的棋盘图案,使得非法拷贝播放的电视机在选定的行中比正常地水平回溯,伴随着相应的水平移位 这些线上的图片信息。 这显着降低了图像的可视性。 在另一个版本中,图片底部过扫描部分的灰色图案导致垂直图像不稳定。 在另一版本中,所选择的水平同步信号变窄,导致不规则的垂直回扫。 还提供了用于从视频信号中去除或衰减这些增强的装置,以允许复制。
