The present invention discloses a method for providing a packet loss detection and down speeding mechanism for maintaining acceptable quality during a video call. Different scenarios of packet loss requiring different down speeding degrees are accommodated by a two-parted method combined by a low-part and a high-part decision and down speeding mechanisms. The method has a consecutively measured packet loss as input, and uses weighted packet loss parameter of recently measured packet loss to decide whether to down speed, and if so, whether the low-part or high-part down speeding mechanism should be used.
