    • A system and method for stereoscopic video teleconferencing provides an immersive virtual meeting experience. Each participant is surrounded by at least two video cameras. The system senses the position of each of the participants and uses this information to select, for each participant, camera pairs to capture a stereo pair of video images of each of the other participants. The system is adapted to isolate the image of each participant from the background. The system transforms the stereo pair images to adjust the perspective for the interocular spacing of each participant. The processed stereo pairs of video images are transmitted to the respective participants. For each participant, the system assembles a stereo video display image of a virtual meeting room, combining the stereo pair images of each of the other participants appropriately sized and positioned. Three-dimensional (3D) virtual objects can also be displayed and manipulated by participants.
    • 用于立体视频电话会议的系统和方法提供了沉浸式的虚拟会议体验。 每个参与者被至少两个摄像机包围。 该系统感测每个参与者的位置,并使用该信息为每个参与者选择相机对以捕获每个其他参与者的立体声视频图像对。 该系统适于将每个参与者的图像与背景隔离开来。 系统转换立体声对图像以调整每个参与者的眼间距的透视图。 经处理的视频图像的立体对被发送给相应的参与者。 对于每个参与者,系统组装虚拟会议室的立体声视频显示图像,组合其他每个参与者的立体声对图像适当地大小和定位。 三维(3D)虚拟对象也可以由参与者显示和操纵。

    • It is possible to reduce the time required for a path recalculation and a path switching upon occurrence of a failure. A path generation unit of a transport control server (TCS) S-1 generates normal path information in accordance with information relating to topology of a network to be established and resource information. Moreover, the path generation unit generates in advance backup path information to be used upon occurrence of a failure in accordance with the prediction topology information and the prediction resource information which have been modified in accordance with a predicted failure position. The path generation unit stores the generated prediction path information in a data storage unit. The TCS (S-1) has a path information report unit which reports the generated normal path information to a node N. The TCS (S-1) also has a failure information acquisition unit which detects occurrence of a failure. When the failure information acquisition unit detects an occurrence of a failure, the path information report unit reports the backup path information stored in the data storage unit to the node N.
    • 可以减少路径重新计算所需的时间和发生故障时的路径切换。 传输控制服务器(TCS)S-1的路径生成单元根据与要建立的网络的拓扑有关的信息和资源信息生成正常路径信息。 此外,路径生成单元根据预测拓扑信息和已经根据预测的故障位置进行了修改的预测资源信息,预先生成要发生故障时的备用路径信息。 路径生成单元将生成的预测路径信息存储在数据存储单元中。 TCS(S-1)具有向节点N报告生成的正常路径信息的路径信息报告单元.TCS(S-1)还具有检测故障发生的故障信息获取单元。 当故障信息获取单元检测到故障的发生时,路径信息报告单元将存储在数据存储单元中的备份路径信息报告给节点N.
