Abstract

A video teleconferencing system and method transfers video teleconferencing signals from a sender to a receiver. The sender determines decision information based on internal or external factors. The sender may or may not generate a video teleconferencing signal depending on the content of the decision information. If generated, the video teleconferencing signal is encoded at the sender and sent to the receiver. Each sender includes at least one memory module for storing the decoded signal, each memory module is one group. The sender updates its memory module with a copy of each sent video teleconferencing signal. The receiver decodes the signal and presents the signal to the user of the receiver. The receiver stores a copy of the signal in a memory module identified with each specific sender.
