Abstract

Nowadays, it is still a challenge to offer high quality and reliable real-time video services over wireless network. In this paper, we studies a new practical scalable video coding (SVC) multicast scheme based on unequal error protection (UEP) framework with priority transmission. Firstly, we propose a 3D layer-based priority ordering method to determine the importance of scalable video bit stream. Then we present an adaptive packetization algorithm to allocate the source and channel code bit rate for ordered layers and guarantee the layers with highest importance could be recovered first. Simulation results show that the proposed scheme offer better performance than existing methods in preserving video quality for different kinds of sequences under various channel conditions.
