In this paper, a comparison of a scalable multiple description coding (MDC) scheme and the forward error correction (FEC) coding using Raptor code for the scalable extension of H.264/AVC (SVC) is presented. Unequal and equal protection of the base and enhancement layer with different amount of redundancy at the average burst lengths of 2, 5 and 20 are considered. The experimental results show that scalable MDC is generally preferable at the low redundancy rate and long average burst length, while FEC using Raptor code is favorite in case of high redundancy rate and the channel with short average burst length for the resilient delivery of scalable video.
