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. |
