Abstract :
A rate control approach is proposed to deal with the low delay H.264/AVC video transmission over channels with burst errors by applying stochastic optimization technique. Based on the exponential rate-distortion and the linear variance prediction model, the one pass rate control algorithm will take into account the channel state and round trip delay, and make an immediate decision on the optimal rate allocation for the video frame. Simulation results show that for different end to end delay constraints and round trip delay, the number of lost frames is significantly reduced, and the average reconstruction peek signal to noise ratio is improved by 0.5-1.6dB, compared with the reference rate control scheme [ARA, 01]
