  • Patent number: 11501731
    Abstract: A process for operating an electronic computing device to assign video streams to watcher devices. The electronic computing device detects objects of interest within a field-of-view of a camera as a function of incident context information. The electronic computing device obtains video display characteristics associated with watcher devices and further determines, based on respective positions of the objects of interest within the field-of-view, a plurality of sub-regions each enclosing at least one of the detected objects of interest and having one or more video attributes. The electronic computing device then assigns, based on the video display characteristics associated with the watcher devices and the video attributes of the sub-regions, each of the sub-regions to a respectively selected one of the watcher devices. The video streams respectively captured corresponding to each of the assigned sub-regions of interest are then transmitted to the respectively selected one of the watcher devices.

  • Patent number: 11095924
    Abstract: A process for providing a time-compressed preview of a pre-buffered video during a push-to-video (PTV) communication session. A video communication device detects a PTV activation command and analyzes a pre-buffered video to detect objects of interest. The video communication device then establishes a PTV communication session with a second video communication device to transmit a time-compressed preview of the pre-buffered video in which some of the video segments in which the objects of interest appear are configured for accelerated playback at the second video communication device. The video communication device transmits a live PTV stream for synchronous playback at the second video communication device only after the transmission of the time-compressed preview of the pre-buffered video is completed.
