Group-of-pictures-based unequal error protection for scalable video coding extension of H.264/AVC


We address the problem of unequal error protection ͑UEP͒ for SNR enhancement layer network abstraction layer ͑NAL͒ units of scalable video coding extension of H.264/AVC standard over wireless packet-erasure channel. We develop a UEP scheme by jointly selecting SNR NAL units and allocating unequal amounts of protection to selected NAL units for every group of pictures in the sequence. A simple heuristic algorithm is proposed to quickly derive the protection pattern. Experimental results demonstrate the proposed UEP scheme provides significant error resilience. © 2009 Society of Photo-Optical Instrumentation Engineers.
