A low-latency lip-synchronized videoconferencing system

Abstract

Audio is presented ahead of video in some videoconferencing systems since audio requires less time to process. Audio could be delayed to synchronize with video to achieve lip synchronization; however, the overall audio latency might then become unacceptable. We built a videoconferencing system to achieve lip synchronization with minimal perceived audio… (More)
