    摘要: 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.

    摘要: 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.

    摘要: 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.

    摘要: 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.

    摘要: 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.

    摘要: An automated system and method for broadcasting meetings over a computer network. The meeting is filmed using an omni-directional camera system and capable of being presented to a viewer both live and on-demand. The system of the present invention includes an automated camera management system for controlling the camera system and an analysis module determining the location of meeting participants in the meeting environments. The method of the present invention includes using the system of the present invention to broadcast an event to a viewer over a computer network. In particular, the method includes filming the event using an omni-directional camera system. Next, the method determines the location of each event participant in the event environment. Finally, a viewer is provided with a user interface for viewing the broadcast event. This user interface allows a viewer to choose which event participant that the viewer would like to view.
