    • PROBLEM TO BE SOLVED: To provide a video conferencing architecture that uses an efficient method for transmitting data between video-conference participants.SOLUTION: A central distributor that receives video images from two or more participants generates, from the received images, composite images that the central distributor transmits back to the participants. Each composite image includes a set of sub images, and each sub image belongs to one participant. In some embodiments, the central distributor saves network bandwidth by removing each particular participant's image from the composite image that the central distributor 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.
    • 要解决的问题:提供一种视频会议架构,其使用在视频会议参与者之间传输数据的有效方法。解决方案:从两个或多个参与者接收视频图像的中央分配器从接收的图像生成合成图像, 中央经销商传回给与会者。 每个合成图像包括一组子图像,并且每个子图像属于一个参与者。 在一些实施例中,中央分配器通过从中央分配器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。
