Abstract
Software and methods are provided for improving contemporary communications between two or more terminal locations of a packet switched network. In a packet switched network incoming packets are stored in buffers until, as in a video conference, playback of the packets occurs. As described herein, a concerted method between storing packets in buffers and adjusting the playback of the packets at a destination terminal locations is provided. In a preferred embodiment, a jitter time is set that estimates the arrival times between at least two packets at the destination terminal location. The jitter time corresponds to a set of conditions for the buffers receiving the incoming packets and for the playback of the packets on a display device. Thereafter, an actual arrival time between incoming packets is measured and compared against the jitter time estimate. If the measured time is faster than or slower than the jitter time estimate, packets are not being received into buffers as desired and adjustments to the jitter time and set of conditions are made. If the measured time is slower than the jitter time estimate, a rapid alteration to the buffers and playback is made. In one embodiment…
