Paper abstract
-----
In this paper, we present an efficient unequal error protection (UEP) scheme for Virtual SPIHT (VSPIHT) coded bitstream. It divides bitstream into two substreams namely critical and noncritical bits, which have different error resilient property. Different BCH codes are used to protect all critical bits and only 30% of the noncritical bits. The remaining noncritical bits are transmitted without any protection. The simulation results demonstrate that proposed three tiers UEP gives 0.2-0.5 dB improvements over equal error protection for binary symmetric channels (BSC).
