Error robustness scheme for H.264 based on LDPC code
With the tremendous increase in the capabilities of wireless multimedia devices and services, the demand to improve quality of such systems within the limited bandwidth resources motivates the interest in robust video transmission. A new unequal error protect (UEP) scheme is proposed based on LDPC code and data partitioning, which can protect much more important bits and correct major error during the transmission over AWGN channel. Our proposed algorithm features assigning an unequal bits number of forward error correction (FEC) to each data partition for H.264, thus, efficiently makes use of available resources. Simulation results demonstrate that this proposed algorithm is more error robust compared to those obtained with the classical EEP technique and common coding mode, such as Turbo code
