    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.

    Abstract translation: 控制器可用于控制各种配件的运行。 可以将访问特定附件（或一组附件）的控制器组织到控制器网络中以便于控制。 控制器网络可以包括各种代理设备，包括桥接和隧道代理，其可以向附件中传递消息，以及从附件转发消息，执行协议转换和/或提供通信安全性。 一些代理设备可以包括决策逻辑，以便能够通过控制器网络中的控制器对一个或多个附件进行协调控制。

    Abstract: Methods for establishing a direct peer-to-peer (“P2P”) connection between two computers are disclosed. In particular, the methods are designed to work in cases where one or both of the computers are connected to a private network, such private networks being interconnected via a public network, such as the Internet. The connections between the private network and the public network are facilitated by network address translation (“NAT”).

    Abstract translation: 公开了在两台计算机之间建立直接对等（“P2P”）连接的方法。 特别地，这些方法被设计为在一个或两个计算机连接到专用网络的情况下工作，这样的专用网络通过诸如因特网的公共网络互连。 通过网络地址转换（“NAT”），便于私有网络和公网之间的连接。
