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.
