	abstract = {Sports analytics is a growing area of interest, both from a computer system view to manage the technical challenges and from a sport performance view to aid the development of athletes. In this paper, we present Bagadus, a prototype of a sports analytics application using soccer as a case study. Bagadus integrates a sensor system, a soccer analytics annotations system and a video processing system using a video camera array. A prototype is currently installed at Alfheim Stadium in Norway, and in this paper, we describe how the system can follow and zoom in on particular player(s). Next, the system will playout events from the games using stitched panorama video or camera switching mode and create video summaries based on queries to the sensor system. Further- more, we evaluate the system from a systems point of view, benchmarking different approaches, algorithms and trade-offs.},

	abstract = {Efficient delivery of video data over computer networks has been studied extensively for decades. Still, multi-receiver video delivery is challenging, due to heterogeneity and variability in network availability, end node capabilities, and receiver preferences. Our earlier work has shown that content-based networking is a viable technology for fine granularity multi-receiver video streaming. By exploiting this technology, we have demonstrated that each video receiver is provided with fine grained and independent selectivity along the different video quality dimensions region of interest, signal to noise ratio for the luminance and the chrominance planes, and temporal resolution. Here we propose a novel adaptation scheme combining such video streaming with state-of-the-art techniques from the field of adaptation to provide receiver-driven multi-dimensional adaptive video streaming. The scheme allows each client to individually adapt the quality of the received video according to its currently available resources and own preferences. The proposed adaptation scheme is validated experimentally. The results demonstrate adaptation to variations in available bandwidth and CPU resources roughly over two orders of magnitude and that fine grained adaptation is feasible given radically different user preferences.},

	abstract = {It is our great pleasure to welcome you to the Multimedia Computing and Networking Conference (MMCN) 2007 at Electronic Imaging! This year{\textquoteright}s MMCN is the 14th installment of the conference series. MMCN has traditionally served as an opportunity for researchers and practitioners to share their perspectives with others interested in the various aspects of multimedia systems and networks. Thanks to the outstanding efforts of our publicity co-chairs Andreas Mauthe, Wei-Tsang Ooi, and Michael Zink and with the additional support of the ACM SIG Multimedia, the program committee had a good number of papers to choose from. Each original submission was reviewed by at least three reviewers, conflicting review results were addressed in email discussions, and all the papers that received favorable reviews were intensely discussed during the program committee{\textquoteright}s day-long meeting on August 26, 2006, that committee members attended either in person, or by IP or POTS audio conference. The average quality of submission was very high, so that we were able to accept 18 full and seven short papers this year. Putting together MMCN 2007 was a team effort. First of all, we would like to thank the authors for their submissions and for choosing MMCN to highlight their work. Our thanks also go to the program committee members and the external reviewers for their excellent job in evaluating the submissions. We also thank the following colleagues who contributed additional reviews: Sakire Arslan Ay, Jacob Chakareski, Beomjoo Seo, and Leslie S. Liu. We would further like to express our gratitude to the Computer Science department of the University of Massachusetts that hosted the PC meeting, and Michael Zink in particular for being gracious hosts in all aspects. We also want to thank SPIE, IS\&T, and ACM SIG Multimedia for making MMCN possible again this year. The program addresses multimedia systems issues under the topics of video coding, systems and measurements, user perception, resource management, streaming scalability, multimedia systems, and multimedia middleware. In addition to the presentation of the research papers, the program features a keynote speech by Ramesh Sarukkai of Yahoo! Inc., and a panel that will discuss Getting in Touch with the Real World - how multimedia systems interact with physical objects. We hope that you will find the program interesting and thought-provoking and that the conference will provide you with a valuable opportunity to share ideas with other researchers from institutions around the world!

	abstract = {Expressing and analysing data dependency in multimedia streams is promising, since content-aware policies at a transport level would benefit from such services. In this paper we present a format-independent dependency model aimed at specifying, validating and reasoning about structural dependency in multimedia streams. Based on this model, we developed a universal dependency description language and a dependency validation service to serve as an infrastructure for content-aware transport layers. Driven by application knowledge, this special form of a cross-layer design enables lower layers to reason about the impact of data loss and drops during transmission while being unaware of the real data format. We outline, how this infrastructure can be used to build content-aware error protection policies and explain how applications need to specify dependency and prepare media streams in order to gain benefits from those policies. While costs and benefits of a dependency model are only quantifiable in conjunction with special policies, we report on the general worst-case costs of our model here.},
