Abstract: Audio/video programming content is made available to a receiver from a content provider, and meta data is made available to the receiver from a meta data provider. The meta data corresponds to the programming content, and identifies, for each of multiple portions of the programming content, an indicator of a likelihood that the portion is an exciting portion of the content. In one implementation, the meta data includes probabilities that segments of a baseball program are exciting, and is generated by analyzing the audio data of the baseball program for both excited speech and baseball hits. The meta data can then be used to generate a summary for the baseball program.

Abstract: A network system includes a client computer that can present multimedia content to a user and an annotation server that can transmit, to the client computer, annotations for the multimedia content. Users can be presented with annotations generated by other users and can create their own annotations that can be viewed by others. Users can be notified of new annotations by an electronic mail (email) message, can create new annotations by email messages, and can easily access a temporal segment of multimedia content corresponding to a new annotation based on information in email messages.

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 network client such as a streaming multimedia player is provided with the capability of changing playback speeds of a multimedia data stream. To change the playback speed, the client requests a different media stream. The client then initiates the new media stream at a point that corresponds in content to the point in the original data stream at which the speed change was requested. To determine the appropriate presentation time in the new media stream, the client refers to a first set of mappings, that maps presentation times in the original media stream to time-correlated presentation times in a primary or reference media stream. The client then refers to a second set of mappings, associated with the primary reference stream, to determine a time-correlated presentation time in the new media stream. The client then initiates playback of the new media stream at the determined presentation time.

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 internet. 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.
