Adaptive audio delay control for multimedia conferencing |
摘要 |
In an illustrative embodiment, an audio/video conferencing system comprises two or more audio/video terminals, in which the transmitted and/or received audio is automatically adjusted to provide synchronization between audio and video during periods of monologue (i.e., single talker active for significant duration). During interactive periods in which more than one talker is active, the audio delay is automatically adjusted to be less than the video delay, thus improving audio conference quality.
