摘要： A system and method for teleconferencing and recording of meetings. The system uses a variety of capture devices (a novel 360° camera, a whiteboard camera, a presenter view camera, a remote view camera, and a microphone array) to provide a rich experience for people who want to participate in a meeting from a distance. The system is also combined with speaker clustering, spatial indexing, and time compression to provide a rich experience for people who miss a meeting and want to watch it afterward.

摘要： An omni-directional camera (a 360 degree camera) is proposed with an integrated microphone array. The primary application for such a camera is videoconferencing and meeting recording, and the device is designed to be placed on a meeting room table. The microphone array is in a planar configuration, and the microphones are located as close to the desktop as possible to eliminate sound reflections from the table. The camera is connected to the microphone array base with a thin cylindrical rod, which is acoustically invisible to the microphone array for the frequency range [50-4000] Hz. This provides a direct path from the person talking to all of the microphones in the array, and can therefore be used for sound source localization (determining the location of the talker) and beam-forming (improving the sound quality of the talker by filtering only sound from a particular direction). The camera array is elevated from the table to provide a near frontal viewpoint of the meeting participants.

摘要： A system that captures both whiteboard content and audio signals of a meeting using a digital camera and a microphone. The system can be retrofit to any existing whiteboard. It computes the time stamps of pen strokes on the whiteboard by analyzing the sequence of captured snapshots. It also automatically produces a set of key frames representing all the written content on the whiteboard before each erasure. The whiteboard content serves as a visual index to efficiently browse the audio meeting. The system not only captures the whiteboard content, but also helps the users to view and manage the captured meeting content efficiently and securely.

摘要： The claimed subject matter provides a system and/or a method that facilitates enhancing incoming data communication connectivity within a network. An analyzer component can evaluate a portion of an incoming data communication targeted for a network to identify a context associated with the data communication. A transfer component can direct the incoming data communication to a cluster within the network based at least in part upon the identified context, wherein the cluster includes a physical entity with pre-existing knowledge of the identified context.

摘要翻译： 所要求保护的主题提供有助于增强网络内的传入数据通信连接性的系统和/或方法。 分析器组件可以评估针对网络的输入数据通信的一部分，以识别与数据通信相关联的上下文。 传输组件可以至少部分地基于所识别的上下文将传入数据通信定向到网络内的集群，其中集群包括具有所识别上下文的预先存在的知识的物理实体。
