    Abstract: Some embodiments provide an architecture for establishing multi-participant video conferences. This architecture has a central distributor that receives video images from two or more participants. From the received images, the central distributor generates composite images that the central distributor 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 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.

    Abstract: Controllers can be used to control the operation of various accessories. Controllers with access to a particular accessory (or group of accessories) can be organized into a controller network to facilitate control. The controller network can include various proxy devices including bridge and tunnel proxies that can relay messages to and from accessories, perform protocol translations, and/or provide communication security. Some proxy devices can include decision logic to enable coordinated control over one or more accessories by the controllers in the controller network.
