Abstract
Described are the architecture of such a system, algorithms for time synchronization during a multiway conferencing session, methods to fight with network imperfections such as jitter to improve synchronization, methods of introducing buffering delays to create handicaps for players with faster connections, methods which help players with synchronization (such as a synchronized metronome during a music conferencing session), methods for synchronized recording and live delivery of synchronized data to the audience watching the distributed interaction live over the Internet.
Claims8
A method for smooth splicing wave fragment comprising:
- selecting a time shift interval;
- performing linear cross-mixing WkW′k=Wk−x during 1-2 ms for backward time shift;
- performing a forward time shift WkW′k=Wk+x and performing linear cross-mixing during a time span of 20 ms if sound data in a playout buffer exceeds a threshold value.
A computer system including a playout buffer module, the playout buffer module comprising:
- means for selecting a time shift interval;
- means for performing linear cross-mixing WkW′k=Wk−x during a first time window for backward time shift;
- and
- means for performing a forward time shift WkW′k=Wk+x and performing linear cross-mixing during a second time window if sound data in a playout buffer exceeds a threshold value.
