	abstract = {Locating content in existing video archives is both a time and bandwidth consuming process since users might have to download and manually watch large portions of superfluous videos. In this paper, we present two novel prototypes using an Internet based video composition and streaming system with a keyword-based search interface that collects, converts, analyses, indexes, and ranks video content. At user requests, the system can automatically sequence out portions of single videos or aggregate content from multiple videos to produce a single, personalized video stream on-the-fly.},

	abstract = {In this article, we evaluate the performance effects of I/O bound workloads on a specific virtual machine, an important component of an enterprise cloud computing infrastructure. In particular, we demonstrate that (1) the I/O workload of one guest system may adversely affect the I/O performance of another for the XEN hypervisor and (2) the general I/O performance is degraded due to various overheads. Next, we have devised a light-weight, complementary, backwards-compatible alternative to hypervisor-based virtualization techniques called Bonsai. Our software provides low-overhead I/O performance isolation by transparently applying traffic shaping to system calls in a cost-effective manner. Using this system, I/O resource consumption can be controlled at a very fine granularity. Furthermore, using video streaming experiments, where we limit the I/O bandwidth available to each service, we show that we are able to achieve the required level of resource isolation on a per process basis with only a negligible CPU overhead and without reducing the I/O performance.},

	abstract = {In this demo, we present DAVVI, a prototype of the next generation multimedia entertainment platform. It delivers multi-quality video content in a torrent-similar way like known systems from Move Networks, Microsoft and Apple do. However, it also provides a brand new, personalized user experience. Through applied search, personalization and recommendation technologies, end-users can efficiently search and retrieve highlights and combine arbitrary events in a customized manner using drag and drop. The created playlists of video segments are then delivered back to the system to improve future search and recommendation results. Here, we demonstrate this system using \mbox{a soccer example.}},
