    Abstract: A system that captures both whiteboard content and audio signals of a meeting using a digital camera and a microphone. The system can be retrofit to any existing whiteboard. It computes the time stamps of pen strokes on the whiteboard by analyzing the sequence of captured snapshots. It also automatically produces a set of key frames representing all the written content on the whiteboard before each erasure. The whiteboard content serves as a visual index to efficiently browse the audio meeting. The system not only captures the whiteboard content, but also helps the users to view and manage the captured meeting content efficiently and securely.

    Abstract: In a client/server network system, multimedia content is streamed from one or more servers to the client. The multimedia content includes multiple media streams that can be streamed to the client from the same server or from different servers. The user is able to modify the playback speed of the multimedia content, allowing the playback to be either speeded up or slowed down.

    Abstract: A skimmed or preview version of multimedia content is provided to a client computer by a server computer using playlists. The skimmed version of multimedia content can be presented to a user of a client computer in less time than presenting the entire multimedia content would require. The server computer maintains skimming information that identifies particular segments of the multimedia content corresponding to the skimmed version. The server computer uses the skimming information to generate a playlist, which in turn is used by the server computer to access the appropriate segments of the multimedia content and provide the segments to the client computer.

    Abstract: A database of objects is distributed between a server computer and multiple client computers as an object oriented virtual world environment (VWE) with multimedia presentation features. A primary database is maintained on the server and includes at least one entry for each object disposed within the VWE. In one implementation a presentation virtual world environment has a multi-user virtual presentation room object (ShowRoom) in which presentation or information element objects (ShowItems) are presented from a server to multiple viewers at multiple client computers. The presentation room object and presentation element objects are global objects in that they are provided from server to client computers as part of a presentation VWE. The presentation element objects provide a model representing a presentation in the presentation VWE. Interface objects at the client computers provide a view of the presentation, with user interface and control elements, which view is separate from the model provided by the presentation element objects.

    Abstract: Annotations are robustly anchored to content. The robust anchoring allows annotations to be associated with the content independently of the format used to store the content. The annotations can be re-anchored to the content after the content has been modified, including modifications to the format used to store the content.

    Abstract: Multimedia content is streamed over a network system from a server computer to a client computer. The client allows a user to enter a variable playback speed and varies the speed at which the multimedia content is rendered at the client. Time-scale modification technology is used to maintain the original pitch of any audio content, thereby maintaining its intelligibility.

    Abstract: The production of synchronization scripts and associated annotated multimedia streams for servers and client computers coupled to each other by a diverse computer network which includes local area networks (LANs) and/or wide area networks (WANs) such as the intermet. Annotated multimedia streams can include a compressed video stream for display in a video window, an accompanying compressed audio stream and annotations. Synchronization scripts include annotation streams for synchronizing the display of video streams with annotations, e.g., displayable events, such textual/graphical data in the form of HTML pages with Java applets to be displayed in one or more event windows. The producer includes a capture module and an author module for capturing video streams and generating annotation streams, respectively. The capture module compresses the video stream using a suitable compression format. Annotation streams include annotation frames which provide either pointer(s) to the event(s) of interest or include displayable data embedded within the annotation stream. Accordingly, each annotation frame includes either an event locator or an event data. In addition, each annotation frame includes an event time marker which corresponds to the time stamp(s) of associated video frame(s) within the video stream. Embedded displayable data include ticker tape data embedded within the annotation stream. Examples of event locators to displayable events include URL addresses pointing to HTML web pages. The video/audio streams and annotation streams are stored in stream server(s) for subsequent retrieval by client computer(s) in a coordinated manner, so that the client computer(s) is able to synchronously display the video frames and displayable event(s) in a video window and event window(s), respectively. In one implementation, annotation streams include a flipper stream for locating HTML pages and a ticker stream which include ticker (tape) data.
