    • Techniques are disclosed for video mixing in a distributed computing environment. For example, a method comprises the following steps. At a first mixing device, one or more local video streams are received from one or more sources local to the first mixing device. The first mixing device generates a first partially-composited video stream, wherein the first partially-composited video stream comprises: (i) a partial set of video elements of the one or more local video streams; and (ii) information about video elements of the one or more local video streams. The first mixing device sends the first partially-composited video stream to at least a second mixing device remote from the first mixing device. The first mixing device and the second mixing device may be part of a video conferencing system.
    • 公开了用于分布式计算环境中的视频混合的技术。 例如,一种方法包括以下步骤。 在第一混合装置中,从第一混合装置本地的一个或多个源接收一个或多个局部视频流。 所述第一混合装置产生第一部分合成的视频流,其中所述第一部分合成视频流包括:(i)所述一个或多个本地视频流的视频元素的部分集合; 和(ii)关于一个或多个本地视频流的视频元素的信息。 第一混合装置将第一部分合成的视频流发送到远离第一混合装置的至少第二混合装置。 第一混合装置和第二混合装置可以是视频会议系统的一部分。

    • A camera emulation server enables integration of real and logical digital video streams within a video surveillance system. The camera emulation server produces a logical digital video stream emulating a real video surveillance camera, in which the logical digital video stream includes data other than original video surveillance data. The camera emulation server provides the logical digital video stream to a video management server via a packet-switched network for integration with a real digital video stream that includes video surveillance data captured by a remote physical video surveillance camera. The video management server routes the logical digital video stream and the real digital video stream to a video receiving device for simultaneous display in respective window panes configured in a tiled format on at least one display device of the video receiving device.
    • 相机仿真服务器使视频监控系统中的真实和逻辑数字视频流集成。 相机仿真服务器产生仿真真实视频监控摄像机的逻辑数字视频流,其中逻辑数字视频流包括除了原始视频监控数据之外的数据。 相机仿真服务器通过分组交换网络向视频管理服务器提供逻辑数字视频流,以与包括远程物理视频监控摄像机捕获的视频监控数据的实际数字视频流集成。 视频管理服务器将逻辑数字视频流和实际数字视频流路由到视频接收设备,用于在视频接收设备的至少一个显示设备上以平铺格式配置的相应窗格中同时显示。
