    • Some embodiments provide an architecture (100) for establishing multi-particpant video conferences. This architecture (100) has a central distributor (125) that receives video images from two or more participants. From the received images, the central distributor (125) generates composite images that the central distributor (125) transmits back to the participants. Each composite image includes a set of sub-images, where each sub-image belongs to one participant. In some embodiments, the central distributor (125) saves network bandwidth by removing each particular participant's image from the composite image that the central distributor (125) sends to the particular participant. In some embodiments, images received from each participant are arranged in the composite in a non-interleaved manner. For instance, in some embodiments, the composite image includes at most one sub-image for each participant, and no two sub-images are interleaved.
    • 一些实施例提供了一种用于建立多参与视频会议的架构(100)。 该架构(100)具有从两个或更多个参与者接收视频图像的中央分配器(125)。 从所接收的图像中,中央分配器(125)生成中央分配器(125)传送回参与者的合成图像。 每个合成图像包括一组子图像,其中每个子图像属于一个参与者。 在一些实施例中,中央分配器(125)通过从中央分配器(125)向特定参与者发送的合成图像中移除每个特定参与者的图像来节省网络带宽。 在一些实施例中,从每个参与者接收的图像以非交错方式排列在复合体中。 例如,在一些实施例中,合成图像对于每个参与者至多包括一个子图像,并且没有两个子图像被交织。
