摘要： A network-based device creates composite video streams containing video images of users for display on video conferencing screens. Video image streams are cascaded through a series of quad boxes to create combined video streams and ultimately the composite video stream. The composite video stream produces a display grid comprised of a plurality of image boxes. The device uses quad box input port mapping to direct a specific video image stream to a specific image box by controlling the cascade path of each video image stream through the quad boxes in creating the composite video stream. A user interface permits a user to selectively determine the layout of user images on the video conferencing screen. Screen layout extends to size of each user image being incrementally controlled and location of each user image being selectively determined depending upon the size and the number of the various user images. By controlling size and location of each user image, the screen display area available for other uses, such as the display of applications programs, is increased.
摘要翻译：基于网络的设备创建包含用户的视频图像的复合视频流，以在视频会议屏幕上显示。视频图像流通过一系列四方框级联，以创建组合视频流，最终形成复合视频流。复合视频流产生由多个图像盒组成的显示网格。该设备使用四方框输入端口映射来将特定视频图像流引导到特定图像盒，通过在创建复合视频流中通过四通道框架控制每个视频图像流的级联路径。用户界面允许用户选择性地确定视频会议屏幕上用户图像的布局。屏幕布局延伸到逐渐控制的每个用户图像的大小，并且根据各种用户图像的大小和数量来选择性地确定每个用户图像的位置。通过控制每个用户图像的大小和位置，增加了可用于其他用途的屏幕显示区域，例如应用程序的显示。

摘要： The invention described herein provides a method and system for foiling a keylogger by creating a custom keyboard driver and passing the keystrokes directly to the browser in an encrypted format. The browser (which is used to access the Internet) has a component that decrypts the keystroke before it is sent to the website. Thus the present invention enables the user to go to any website and enter sensitive information (passwords, credit card numbers, etc.) without the keystrokes being intercepted by Keyloggers. In general terms, the invention described herein provides a method and system for (1) modifying the keyboard driver, (2) encrypting the keystrokes between the keyboard driver and the browser, and (3) notifying the user if the invention has been compromised.
摘要翻译：本文描述的本发明提供了一种用于通过创建自定义键盘驱动器并以加密格式将键击直接传递到浏览器来打字键盘记录器的方法和系统。浏览器（用于访问互联网）有一个组件，在将其发送到网站之前解密按键。因此，本发明使得用户能够访问任何网站并输入敏感信息（密码，信用卡号码等），而键盘记录器不会被按键击中。一般来说，本文描述的发明提供了一种用于（1）修改键盘驱动程序的方法和系统，（2）加密键盘驱动程序和浏览器之间的按键，以及（3）如果本发明已经受到损害，通知用户。
