Summary:Scalable video coding technologies provide adaptive video applications in heterogeneous and polytropical conditions. However, the highly hierarchical feature makes the loss or unsuccessful recovery of the base-layer to be catastrophic. In this paper, a distributed scalable video coding scheme using the new advances of compressed sensing is proposed to solve this problem at the energy-constrained encoder. The wavelet coefficients of the video frames have inherent fidelity scalability which is utilized in our scheme. Furthermore, the democracy of measurements reduces the risk of base-layer loss over the packet loss channel. Experimental results show that our scheme outperforms the existing scalable compressed sensing scheme by about 2 dB.
