Workshop on “Challenges and Solutions for the Mobile Video Operator”
14th September 2012, Alcatel-Lucent Bell Labs, Paris


Ranked top three at the Future Internet Award, the MEDIEVAL project researches and develops innovative technology for video based communications in the next generation Mobile Internet. Starting from current trends in the industry (e.g. Manufacturers and Mobile Telecommunication Operators), the project takes an holistic view at the video distribution value chain and proposes end-to-end solutions introducing specific enhancements at the different layers of the IP protocol stack. In the MEDIEVAL network, a multi-mode mobile device (e.g., enabled with WIFI and Cellular technology) is able to freely roam across heterogeneous wireless access while enjoying optimized Quality of Experience. The combination of flattened IP networks providing unicast and multicast support, intelligent content caching and distribution (CDN) solutions and QoE driven optimizations, enables new use cases that renew the Mobile Operator's role in the video value chain.

In this context, MEDIEVAL invites experts from the academia and the industry for a one-day workshop to be hosted at Alcatel-Lucent Bell Labs, Paris. The main goal of the workshop is to highlight challenges, state of the art results and future research directions in Mobile Video. We are especially interested in the upcoming challenges Mobile Operators will face in the video storm and what mid-long term solutions are yet to be investigated.

The workshop will feature an opening keynote speaker and it will be based on a number of presentations from industry’s key-players and leading academia representatives. In addition MEDIEVAL will partner with other research programs invited to present their innovations. During the coffee breaks, MEDIEVAL staff will drive the participants through our live demos and demonstrate key concepts on three different use cases. The workshop will close with a panel entitled "Will OTT Rule?".

Title: When Coding Met QoE - Making Network Coding go from Theory to Practice [PDF]

Abstract: We present some approaches that illustrate how network coding can improve network efficiency and survivability under different Quality of Experience (QoE) metrics. The notion of QoE itself is highly dependent on application-specific user experience expectations. We first consider QoE as a probability of interruption of video, and show that coding can be used to reduce the probability of interruption, with a behavior akin to error exponents. We apply these principles to stitch effectively cellular networks with 802.11 in order to obtain very low probability of interruption while accessing almost exclusively the 802.11 network. The second QoE measure we consider is high, reliable rate under wireless losses. We show how network coding can avoid interruptions in TCP/IP, by coding over temporary network effects that can lead to significant service interruptions and also by coding over multiple networks simultaneously using a coded version of multipath TCP. In the context of distributed storage, we consider the use of coding to reduce the energy use by fixing a QoE metric of probability of blocking of a request at a data center. Finally, we consider a fourth type of QoE, which is the ability to share socially video in a proximity-based network. The QoE in this case is to provide a seamless social viewing experience over heterogeneous devices. We use network coding in a peer-to-peer proximate network to achieve this QoE.

Title: Mobile Video in the context of mobile offload [PDF]

Abstract: Mobile Video is the most growing traffic on the Internet. With the explosion of wireless access networks, the video streaming services are being challenged and the user experience is currently broken. The talk will present the conditions by which the user experience is broken and what conditions are causing these issues. The talk will also present what recent video technologies changes have improved some of the challenges and what challenges are left. The talk’s main objective is to present the current situation so that options can be investigated to solve the current challenges.

Title: Latest advances in mobile video technologies [PDF]

Abstract: As a recognized pioneer of early cellular technologies in the 80’s and 90’s, InterDigital continues to be a leader in the development of advanced wireless technologies that are at the core of mobile devices, machines, networks and services worldwide. In his presentation, Juan Carlos Zuniga will address the latest advances in mobile video technologies designed to enhance the user's experience while optimizing the network operator's resources utilization.

Title: Mobile Network evolution for better video delivery efficiency [PDF]

Abstract: In this presentation, Pierrick Seite, will give an overview of the challenge brought by mobile video and resulting network evolution. Presentation will start with marketing considerations giving a global survey of the mobile video demand over different regions (Asia/Europe/US). Starting from the, now well known, forecast evolution of the mobile data demand, Pierrick Seite will show that a large part of this traffic is due to mobile video. Of course mobile network can be upgraded to face such traffic explosion; however this solution is not financially acceptable for an operator. Hence, new way for mobile video service delivery needs to be explored. Among major evolutions foreseen, are delivery network as well as the content architecture evolutions. Basically we have two complementary approaches for the delivery: broadcast and unicast. Pierrick Seite will go through various broadcast initiatives, including failure in the past, such as DVB-H. Regarding broadcast, the presentation will focus on the only solution still alive, eMBMS; also saying few words about the trial Orange has with ALU.  Then the presentation will focus on unicast architecture delivery with offloading, basically 3GPP/BBF interworking architecture. Then, the presentation will go rapidly through distribution of network architecture, considering that the distribution of the content delivery (CDN) might lead to the distribution of the mobile network functions. It drives to high-level DMM considerations which will conclude the presentation.

               Title: Smooth delivering for layered streaming in P2P networks [PDF]

Abstract: Scalable Video Coding (SVC) content delivery over peer-to-peer (P2P) networks has drawn great interest from its ability to support large number of users, while simultaneously handling client heterogeneity, in terms of download bandwidth, terminal capabilities and user preferences, using content adaptation. In order to support such system, three essential components need to be considered: overlay construction, layer selection and data scheduling, and adaptation. In this presentation, we consider a pull-based P2P network for delivering optimized SVC layers, and we present a design of algorithms being adopted in ENVISION project for assuring  a smooth quality of experience.

Title: Real-time video quality estimation & monitoring using fuzzy expert system [PDF]

Abstract: Quality of experience (QoE) of multimedia applications has been the focus of extensive research in the last decade. QoE provides valuable input in order to assess the user satisfaction of a particular service. QoE measurement is challenging as it tries to measure a subjective metric that depends on a number of factors that cannot be simply be measured. Involving end-users in the measurement of QoE is simply not feasible for its cost. The objective therefore is to estimate the QoE based on objective QoS metrics. In this work, we propose a fuzzy expert system to estimate quality of experience of video traffic. A number of subjective tests with end-users allowed building a learning base to correlate QoS metrics like packet loss and jitter with user experience in order to define membership functions and fuzzy inference rules for real time estimation of QoE. The estimation algorithm and methodology are implemented in MMT (Montimage Monitoring Tool) to provide a real time monitoring of video applications.

Title: Putting everything together: how mobile networks should evolve to cope with video traffic [PDF]

Abstract: The MEDIEVAL project is a 3-year EU funded project that is tackling the challenges posed by the increasing video traffic load in mobile networks. Following a cross-layer approach, that benefits from the interaction among the different layers, the designed architecture aims at achieving performance improvements unattainable with individual developments. This talk will present the overall MEDIEVAL architecture, which is composed of 4 major pillars: i) enhanced wireless access support, ii) novel IP mobility architecture, iii) transport optimizations and iv) network-aware video services.
