Robust Multimedia Coding: Information Theory and Practical Architectures by Rohit Puri Doctor of Philosophy in Engineering Electrical Engineering and Computer Sciences University of California, Berkeley Professor Kannan Ramchandran, Chair The ever increasing proportion of multimedia content over the Internet has fueled tremendous research activity in the field of robust multimedia transmission ...

Over the past decade, rateless codes, i.e., digital fountain codes, have emerged as an efficient and robust solution for reliable data transmission over packet erasure networks and a particularly suitable one for multicasting and broadcasting applications where users may experience variable channel conditions and packet loss rates, such as mobile environments. Luby Transform (LT) and Raptor cod...

The data sensed by different sensors in a sensor network is typically correlated. A natural question is whether the data correlation can be exploited in innovative ways along with network information transfer techniques to design efficient and distributed schemes for the operation of such networks. This necessarily involves a coupling between the issues of compression and networked data transmi...

In this paper, we present a scheme for robust scalable video multicast based on distributed source coding principles. Unlike prediction-based coders, like MPEG-x and H.26x, the proposed framework is designed specifically for lossy wireless channels and directly addresses the problem of drift due to packet losses. The proposed solution is based on recently proposed PRISM (power efficient robust ...
