摘要： A system and method for temporal synchronization of media streams in multimedia collaborative applications (i.e., a multi-user distributed applications used for interaction, both in the synchronous and asynchronous fashion among a group of users) in a wide-area distributed environment. The invention presents two abstractions; event streams and collaboration space, that together provide for coarse-grained temporal synchronization by using separate streams for different media and synchronizing the streams at the client location. VCR-like controls are also provided on groups of components in a collaborative application. The event stream provides many services such as replication, persistence, buffering, reading, and writing to archive. By implementing simple interfaces, existing collaborative applications, media players, and encoders become components that can be used to build complex multimedia collaborative applications. To efficiently implement a seeking function on a data component, the present invention introduces a framework for application-specific updates to a component state.

摘要： A method and apparatus for compressing video data to improve its tolerance to error, especially with a low bit rate network. With this invention video data is divided into a number of frames and each frame is divided into a number of macroblocks. A dependency count is assigned to each macroblock, and if the dependency count for the macroblock exceeds or is equal to a threshold, the dependency block is intra-coded using low bit rate coding algorithm. If the dependency count is below the threshold, the macroblock is inter-coded.

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 client-based system for the fault tolerant delivery of real-time or continuous data streams, such as real-time multimedia streams, e.g., live audio and video clips. Multimedia servers are grouped into two or more sets, for example wherein a first set includes one or more primary servers using odd-numbered ports and a second set includes one or more secondary servers using even-numbered ports. The client requests a multimedia stream through a control server or gateway which routes requests to the multimedia servers; and the client receives the stream directly from a selected (primary) server. The client automatically detects load imbalances and/or failures (complete or partial) and dynamically switches to a secondary server in order to continue receiving the real-time multimedia stream with minimal disruption and while maintaining a balanced load across multiple servers in a distributed network environment. The determination can be made based on: the received bit or frame rate (for video); a bit rate or sample rate (for audio); monitoring a delivery rate or for packets arriving out of order: for example using packet numbering mechanisms available in TCP; sequence numbering or time stamp capabilities of RTP (in combination with the User Datagram Protocol (UDP)). In any case, the determination could be based on the rate measurement or monitoring mechanism falling below (or exceeding) some threshold. Alternately, the primary server or the control server could send an explicit distress or switch signal to the client. An explicit signal can be used for example to switch clients in phases with minimal disruption.
摘要翻译：一种基于客户端的系统，用于实时或连续数据流的容错传送，例如实时多媒体流，例如现场音频和视频剪辑。多媒体服务器被分组为两个或多个集合，例如其中第一集合包括使用奇数端口的一个或多个主服务器，而第二集合包括使用偶数端口的一个或多个辅助服务器。客户端通过将请求路由到多媒体服务器的控制服务器或网关来请求多媒体流; 并且客户端直接从所选（主）服务器接收流。客户端自动检测负载不平衡和/或故障（完全或部分）并动态切换到辅助服务器，以便以最小的中断继续接收实时多媒体流，同时在分布式网络环境中跨多个服务器保持平衡负载。可以基于以下方式进行确定：接收的位或帧速率（用于视频）; 比特率或采样率（音频）; 监视传送速率或者不按顺序到达的数据包：例如使用TCP中可用的分组编号机制; RTP的序列号或时间戳功能（与用户数据报协议（UDP）组合）。无论如何，确定可以基于速率测量或监测机制低于（或超过）一些阈值。或者，主服务器或控制服务器可以向客户端发送明确的遇险或切换信号。例如，可以使用显式信号来以最小的中断阶段切换客户端。

摘要： A multimedia stream is multicasted. A request to perform the multicast is received. A plurality of distribution nodes are assigned to provide the multicast to a plurality of receivers. The assignment of a node is based on the transformation capabilities of that node. The multicast is then performed and the assigned node performs its transformation. The transformed multicast is distributed to a receiver which is suitable for receiving the transformed multicast.

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.
