Abstract

In this paper, we present a new error robust method for H.264 video transmission. This scheme uses unequal error protection (UEP) and automatic repeat request (ARQ) protocol to provide better error-resilience performance and efficiently bandwidth utilization. In order to realize the layered video coding with transport prioritization, the proposed scheme adopts different HARQ (hybrid ARQ) schemes for the different priority-data. Simulations are conducted over the AWGN and Rayleigh channels, respectively. Simulation results demonstrate that the UEP scheme improves transmission performance and achieves better video quality than equal error protection (EEP) scheme over wireless channels under the same bandwidth.
