摘要： A program distribution system includes a plurality of set-top boxes that receive broadcast programming and segmentation data from content and information providers. The segmentation information indicates portions of programs that are to be included in skimmed or condensed versions of the received programming, and is produced using manual or automated methods. Automated methods include the use of ancillary production data to detect the most important parts of a program. A user interface allows a user to control time scale modification and skimming during playback, and also allows the user to easily browse to different points within the current program.

摘要： Media content is streamed from a server computer to a client computer. A media file format is used to store data for multiple timeline-altered streams that provides support for switching between the different timeline-altered streams during their presentation. In one aspect, a user can switch between different timeline-altered streams. Upon receiving a user request to switch to a particular timeline-altered stream (the target stream), the client computer accesses a time code stream data object corresponding to the current data unit being presented. The time code stream data object identifies a primary stream presentation time corresponding to the data unit. The client then uses the primary stream presentation time to index into a table of mappings to byte offsets. The table provides a mapping of the primary stream presentation time to a corresponding byte offset of the target stream.

摘要： In a networked client/server system, media content is streamed from a server computer to a client computer. A media file format is used to store data for multiple timeline-altered streams that provides support for switching between the different timeline-altered streams during their presentation. According to one embodiment, a time code stream includes multiple data objects mapping corresponding timeline-altered stream data units to primary stream presentation times, and an index table mapping primary stream presentation times to timeline-altered stream byte offsets.

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： 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.
