Abstract
Applying ARQ to real time video communication can significantly increa se transmission delay due its retransmission operations. We analyze th is delay and propose an adaptive error control scheme that uses acknow ledgment from the receiver to reduce the delay. We evaluate this schem e using a computer simulation and show that the proposed scheme can re duce the delay by controlling the amount of video data by changing the quantization step size and video frame skipping. It also offers accep table video quality as confirmed by a subjective evaluation test.
