Abstract :
In this paper, a low-complexity unequal error protection (UEP) of H.264/AVC coded video using adaptive hierarchical quadrature amplitude modulation (HQAM), which takes into consideration the non-uniformly distributed importance of intracoded frame (I-frame) and predictive coded frame (P-frame) is proposed. Simulation results show that in terms of average peak signal-to-noise ratio (average PSNR), our proposed (EEP) scheme outperforms the equal error protection (EEP) by up to 5 dB
