Abstract: The present invention allows communicating devices to control the amount of compression used in packet sessions for transmitting streaming media to and from each other. When a communicating device detects a decrease in performance or quality of service indicative of a limited bandwidth condition, the amount of compression for the current or subsequent sessions is temporarily increased to allow the currently available bandwidth to support the session or subsequent sessions. After a set period of time, or when the limited bandwidth condition is removed, communications associated with the sessions can revert back to transporting uncompressed data or reducing the amount of compression for the sessions, thus using more of the available bandwidth.
