With a low complexity and high successful probability, RaptorQ code is considered as an efficient solution for media transmission. However, RaptorQ code is optimal for the purpose of single layer transmission. Therefore, RaptorQ code is not suitable for dependent media transmission, where the successful decoding of the least important layer depends on the successful of the more important layer, especially in Scalable video coding (SVC). In this paper, we propose an unequal error protection scheme to protect layers video in SVC using RaptorQ code named content-aware RaptorQ. Specifically, the layers are encoded based on a window selection probability so that the least important media layers is utilized to protect data of more important media layers. The simulation results demonstrate that the successful decoding probability of the proposed method is improved by 105%, relative to that of RaptorQ.
