Scalability is an attractive solution to the problems posed by modern multimedia transmission systems. The key for better performance in scalable coding is joint rate distortion optimization. We present a new stochastic model for scalable coding which models the dependencies among layers, and we derive an optimal joint quantizer selection scheme for memoryless Gaussian sources. Simulation results...
In several telepresence applications the transmitting end is resource constrained, hence multi-view video has to be source coded and transmitted to a location where stereo matching is performed. The effect of video source coding on stereo matching techniques is presently not well understood. In this paper, we present an analysis which quantitatively demonstrates the impact of standard video coding...
While multiview video coding typically focuses on the rate-distortion performance of compressing all frames of all views, we address the problem of designing a pre-encoded frame structure for a streaming server to enable a new functionality-interactive multiview switching, where a streaming client can send requests periodically to a server to switch to different views while continuing uninterrupted...
High error rate is critical to the wireless video transmission. Our paper tackles the problem of robust video streaming over error-prone channels. Basing on an autoresilient multiple-description coding method and a multi-path transmission strategy, further study is done on the computational complexity of rate-distortion optimization for video coding and transmission. A unitary-optimized operation...
