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.
