Keynote Talk

Speaker: Prof Stefano Tubaro, Politecnico di Milano, Italy

Topic: "Robust Streaming, Error Resilience and Error Concealment"

Authors: Matteo Naccari, Marco Tagliasacchi and Stefano Tubaro

 

Abstract

The transmission of coded data through noisy channels, such as wireless links, has become a significant issue for a large variety of applications, calling for innovative methodologies and techniques to improve the resiliency of coded video bitstreams to packet losses. Although the technology advances in the communication devices will provide more reliable transmission channels, data losses are intrinsic in the emerging peer-to-peer video technologies leading to new challenges for the robust video streaming.

In this talk an overview of the error resilience problem in the video coding scenario will be provided, outlining a classification based on where error resiliency can be added in a video coding architecture (transmitter side, receiver side, network infrastructure, etc.) and which are the most relevant coding tools that can be adopted to this purpose (both normative tools, e.g. FMO, and non-normative tools, e.g. forward error codes, error concealment, etc.). When, at the encoder side, protection data is added to the original bitstreams, it is interesting to study what happens if the power correction capabilities of the systems are exceeded. Due to the predictive nature of the conventional video codecs, the effects of packet losses will propagate along time leading to the degradation of a significant number of decoded frames. In this scenario the use of new approaches (like those based on the Distributed Video Coding paradigm) might constitute a valid alternative to the widely adopted forward error correction techniques.

A discussion of future trends and open issues in the development of error resilient coding architectures for robust video streaming will conclude the talk.

 

About the Keynote Speaker

Stefano Tubaro was born in Novara in 1957. He completed his studies in Electronic Engineering at the "Politecnico di Milano", Italy, in 1982. He then joined the "Dipartimento di Elettronica e Informazione" of the "Politecnico di Milano", first as a researcher of the National Research Council, then (in November 1991) as an Associate Professor, and from December 2004 as a Full Professor. In the first years of activities Stefano Tubaro worked on problems related to speech analysis; motion estimation/compensation for video analysis/coding; and vector quantization applied to hybrid video coding.

In the past few years, his research interests have focused on image and video analysis for the geometric and radiometric modeling of 3D scenes; advanced algorithms for video coding and sound processing. Stefano Tubaro authored more than 150 scientific publications on international journals and congresses. He co-authored two books on digital processing of video sequences. He is also a co-author of several patents relative to image processing techniques. Stefano Tubaro coordinates the research activites of the Image and Sound Processing Group (ISPG) at the "Dipartimento di Elettronica e Informazione" of the "Politecnico di Milano" that is involved in several research programs funded by industrial partners, the Italian Government and by the European Commission.
