摘要： In this invention streaming video data is embedded within a panoramic image for display. The invention teaches a method and system for displaying an image of a scene of interest from a stored environment map of the scene and from video data of the scene. The method includes the steps of: (A) receiving and storing the video data of the scene; (B) selecting an orientation of the scene; (C) retrieving video data according to the selected orientation of the scene; (D) rendering the environment map according to the selected orientation of the scene to generate a first image for the selected orientation; (E) synchronously combining the retrieved video data and the first image to form a composite image for the selected orientation of the scene of interest; and (F) displaying the composite image. In one embodiment the method for displaying the image of the scene of interest further includes a step of continuously receiving video data packets that include image data and sound data. In this embodiment the sound data is continuously played while selected portions of the image data are displayed. In another embodiment, the method for displaying the image of the scene of interest further includes a step of layering the video data and the first image generated by rendering the environment map. In the present invention layering techniques include, for example, drawing order layering, z-buffer-hiding layering, and chroma-key layering.

摘要： A method and system for manipulating or modifying identifiable objects in a standard broadcast or Internet-based multimedia stream according to a control specification and a content specification. Viewers and/or organizations can independently specify acceptable levels of content on multiple dimensions to satisfy the content specification while minimizing the filtering or blocking to the viewers. A fuzz ball control specification is provided for masking some portion of a video frame. Several fuzz ball specifications can be overlaid to address multidimensional content specifications or rating systems. The manipulation of the multimedia stream can take place at the client (set-top box or computer), intermediate node, the content server or a combination thereof. Proxy servers can modify content specifications for outgoing requests, enabling organizations to specify intranet-wide policies. Multicasting can be supported by using a single stream delivered to multiple clients, each modifying the video using a different specification. The specification to facilitate modification can be done at different granularity levels: the video, a group of frames, or individual frame level and can also be time-based. various protocols can be used to provide the content and/or control specification, including the VBI of a standard broadcast, PICS, RTSP and MPEG protocols.

摘要： A method and apparatus for scheduling the transmission of a number of data streams over a common communications link, where each of the data streams conforms to a corresponding set of flow control parameters. Each of the data streams to be transmitted on the communications link is stored in a corresponding queue. The status of each queue is maintained, and a target transmission time is calculated for each queue. Signals are then generated for each queue at a time at least after the target transmission time, and these signals are used to indicate to a corresponding queue that it can transmit a cell on the link. Upon reception of a corresponding signal, a queue then transmits at least one cell onto the communications link.

摘要： In standard token-based LANs (e.g., FDDI, Token Ring) an equal share of the ring bandwidth is made available to each node. Certain nodes (e.g., bridges, routers, servers) require a larger representation (bandwidth) than other nodes. A surrogate (bridge/router) node is presented which achieves this in a standard compliant manner. The bridge/router may serve as a surrogate on each ring representing multiple stations from the other ring. The multiplicity of stations is adjusted either statically or dynamically to provide sufficient added bandwidth to the surrogate to reduce delay and packet loss characteristic of the conventional single station bridge or router. The increased bandwidth utilization and FDDI ring performance resulting from the implementation of this invention is transparent to the individual stations and the ring in a way that is advantageous to both single media and multimedia usages within defined network local and non-local areas.
