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.

Distributed video mixing

Area tracking systems including a plurality of short range sensors that are communicatively connected to a server and methods of tracking electronic devices. The electronic devices are tracked by polling for the electronic devices, the polling including transmission of electronic addresses corresponding to the electronic devices and determining whether a reply to the poling is received. The electronic addresses are each stored on one of a plurality of lists. Each of the lists may be polled at a different frequency and may include a different number of electronic device addresses.

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.
