ICME 2015: Over-the-Top Content Delivery: State of the Art and Challenges Ahead

Supported by http://www.dash-player.com/
Tutorial at ICME 2015
June 29 - July 3, 2015
Torino, Italy

Abstract: Over-the-top content delivery is becoming increasingly attractive for both live and on-demand content thanks to the popularity of platforms like YouTube, Vimeo, Netflix, Hulu, Maxdome, etc. In this tutorial, we present state of the art and challenges ahead in over-the-top content delivery. In particular, the goal of this tutorial is to provide an overview of adaptive media delivery, specifically in the context of HTTP adaptive streaming (HAS) including the recently ratified MPEG-DASH standard. The main focus of the tutorial will be on the common problems in HAS deployments such as client design, QoE optimization, multi-screen and hybrid delivery scenarios, and synchronization issues. For each problem, we will examine proposed solutions along with their pros and cons. In the last part of the tutorial, we will look into the open issues and review the work-in-progress and future research directions.

The tutorial will be held on June 29, 2015 in the afternoon.

Slides will be provided on time and a preliminary version (from previous presentations) can be found here and here.

Biography of Presenters

Christian Timmerer received his M.Sc. (Dipl.-Ing.) in January 2003 and his Ph.D. (Dr.techn.) in June 2006 (for research on the adaptation of scalable multimedia content in streaming and constraint environments) both from the Alpen-Adria-Universität Klagenfurt. He is currently an Associate Professor at the Institute of Information Technology (ITEC) within the Multimedia Communication Group. His research interests include immersive multimedia communication, streaming, adaptation, Quality of Experience, and Sensory Experience.

He has published more than 150 papers in these areas and he has organized a number of special sessions and issues in this domain, e.g., “Special Session on MMT/DASH” (MMsys 2011, followed by a special issue in Signal Processing: Image Communication, 2012), “Special Issue on Adaptive Media Streaming” (IEEE JSAC, published 2014). Furthermore, he was the general chair of WIAMIS 2008, QoMEX 2013, and QCMan 2014; will be general chair of ACM Multimedia Systems 2016. He is an editorial board member of IEEE Computer, associate editor for IEEE Transactions on Multimedia, area editor for the Elsevier journal on Signal Processing: Image Communication and a key member of the Interest Groups (IG) on Image and Video Coding as well as Quality of Experience and Director of the Review Board of the IEEE Multimedia Communication Technical Committee. Finally, he writes a regular column for ACM SIGMM Records where he serves as an editor and he is a member of the ACM SIGMM Open Source Software Committee. Dr. Timmerer participated in the work of ISO/MPEG for more then 10 years, notably as the head of the Austrian delegation, coordinator of several core experiments, co-chair of several ad- hoc groups, and as an editor for various standards, notably the MPEG-21 Multimedia Framework and the MPEG Extensible Middleware (MXM which became MPEG-M). His current contributions are in the area of MPEG-V (Media Context and Control) and Dynamic Adaptive Streaming over HTTP (DASH), for which he also serves as an editor. He received various ISO/IEC certificates of appreciation.


Ali C. Begen is with the Video and Content Platforms Research and Advanced Development Group at Cisco. His interests include networked entertainment, Internet multimedia, transport protocols and content delivery. Ali is currently working on architectures and protocols for next-generation video transport and distribution over IP networks, and he is an active contributor in the IETF and MPEG in these areas. Ali holds a Ph.D. degree in electrical and computer engineering from Georgia Tech. He received the Best Student-paper Award at IEEE ICIP 2003, the Most-cited Paper Award from Elsevier Signal Processing: Image Communication in 2008, and the Best-paper Award at Packet Video Workshop 2012. Ali has been an editor for the Consumer Communications and Networking series in the IEEE Communications Magazine since 2011 and an associate editor for the IEEE Transactions on Multimedia since 2013. He is a senior member of the IEEE and a senior member of the ACM. Further information on Ali’s projects, publications and presentations can be found at http://ali.begen.net.
