    摘要： Embodiments of the present invention include a video server that can detect and track the image of a pointing indicator in an input video stream representation of a computer display. The video server checks ordered frames of the video signal and determines movements for a pointing indicator such as a mouse arrow. Certain motions by the pointing indicator, such as lingering over a button or menu item or circling a button or menu item can provoke a control action on the server.

    摘要翻译： 本发明的实施例包括可以在计算机显示器的输入视频流表示中检测和跟踪指示指示符的图像的视频服务器。 视频服务器检查视频信号的有序帧，并确定诸如鼠标箭头的指示指示器的移动。 指示指示器的某些运动，例如挥动按钮或菜单项或旋转按钮或菜单项可能会引起服务器上的控制动作。

    摘要： Blogs (and other information sources) are recommended to a user based history of user's online activities. The system: (1) processes the user's web history, (2) identifies blog posts (and web pages) that link to pages read by the user, (3) generates multiple relevance scores for each identified post/page, and (4) produces multiple rankings of the corresponding source blogs (and web sites) by aggregating individual relevance scores (or combinations of relevance scores), according to users' preferences. The system allows the discovery of information sources that are likely to be interesting to the user and allows sources lost in the “long tail” to be seamlessly discovered.

    摘要： Embodiments of the present invention enable the extraction, classification, storage, and supplementation of presentation video. A media system receives a video signal carrying presentation video. The media system processes the video signal and generates images for slides of the presentation. The media system then extracts text from the images and uses the text and other characteristics to classify the images and store them in a database. Additionally, the system enables viewers of the presentation to provide feedback on the presentation, which can be used to supplement the presentation.

    摘要： A method for navigating instructional video presentations is disclosed. The method includes determining a pause mode of a video presentation, and playing the video presentation on a display device. The video presentation has one or more predetermined pause positions. The method also includes, while playing the video presentation, determining that the video presentation has reached one of the one or more pause positions. The method further includes, in accordance with a determination that the video presentation is in a first pause mode, pausing the video presentation at the one of the one or more pause positions and maintaining a display of a paused frame of the video presentation, and, in accordance with a determination that the video presentation is in a second pause mode distinct from the first pause mode, continuing to play the video presentation through the one of the one or more pause positions.

    摘要： A system and method for identifying key frames of a presentation video that include stationary informational content. A sequence of frames is obtained from a presentation video and differences of pixel values between consecutive frames of the sequence of frames are computed. Sets of consecutive frames that are stationary are identified, wherein consecutive frames that are stationary have a proportion of changed pixel values below a first predetermined threshold, and wherein pixel values are deemed to be changed when the difference between the pixel values for corresponding pixels in consecutive frames exceeds a second predetermined threshold. Next, a set of key frames that include stationary informational content is retained. The set of key frames that include stationary informational content is then displayed for user interaction.
