An efficient coding system is required for immersive teleconference to transmit stereo video. We propose a novel stereo video coding system by exploiting mesh-based disparity estimation and compensation scheme to achieve high coding efficiency and view synthesis ability. Based on the base-layer-enhance-layer structure, this system can provide stereoscopic scalability and compatihility to standa...

This paper proposes an efficient layer-correlated scheme to reduce the bit cost for motion vectors in the 3D wavelet coding. Previous works show that incorporating motion alignment into the lifting structure enables the 3D wavelet coding to provide a competitive performance to the state-of-the-art JVT standard. In general, the temporal wavelet decomposition consists of multiple layers, while ea...

| We examine the rationale for and systems aspects of using layered coding for the transmission of images and video over heterogeneous communication networks. We advocate Multi-resolution Layered Coding (MLC) and present architectural alternatives that can support it within the scope of existing standards and technologies. Since the premise of layered coding is controlled loss, the issues of er...

Resource allocation in wireless networks typically occurs at PHY/MAC layers, while random network coding (RNC) is a network layer strategy. An interesting question is how resource allocation mechanisms can be tuned to improve RNC performance. By means of a differential equation framework which models RNC throughput in terms of lower layer parameters, we propose a gradient based approach that ca...

As the MPEG core experiments have shown, the current FGS video coding scheme suffers from a 2~3dB coding efficiency loss compared with the non-scalable single-layer coding for a wide range of bit rates. This is mainly due to the open-loop enhancement structure that ensures drifting free coding. Two categories of schemes are proposed to address this issue with the same basic idea, i.e., introduc...
