  • Patent number: 6230172
    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.

  • Patent number: 6173406
    Abstract: Authentication methods, systems and computer program products ensure that user media streaming requests originate with web documents having an authorized URL. The user makes a streaming request to a media server with a URL including a URL prefix, a path, and the name of a media work to be performed, which URL the media server compares with earlier made URL entries in a pre-established database. If there is a URL correspondence between a URL in the pre-established database and the URL extracted from the HTML document received by the browser from a web server, then streaming of the particular work is authorized.
