pixie a Jukebox architecture to support efficient peer content exchange
ACM Multimedia, 2002Co-Authors: Sami Rollins, Kevin C AlmerothAbstract:Peer-to-peer (P2P) content exchange has recently gained attention from both the research and industrial communities. The dynamic nature of peer networks and the resource constraints of peer hosts have introduced a number of unique technical challenges that must be addressed to make large-scale P2P content exchange applications viable. In this work, we present and evaluate Pixie, an architecture that integrates one-to-many distribution of content and peer networks. Pixie provides a valuable data location service as well as a number of scalability properties both in terms of data location and content distribution. Our results indicate that, using a one-to-many scheme, we can significantly reduce the resources consumed in searching for and distributing content across peer networks. These scalability properties will become increasingly important as peer content exchange is extended to support more advanced applications.

an alternative paradigm for scalable on demand applications evaluating and deploying the interactive multimedia Jukebox
IEEE Transactions on Knowledge and Data Engineering, 1999Co-Authors: Kevin C Almeroth, Mostafa H AmmarAbstract:Straightforward, one-way delivery of audio/video through television sets has existed for many decades. In the 1980s, new services like pay-per-view and video-on-demand were touted as the "killer applications" for interactive TV. However, the hype quickly died away, leaving only hard technical problems and costly systems. As an alternative, we propose a new Jukebox paradigm offering flexibility in how programs are requested and scheduled for playout. The Jukebox scheduling paradigm offers flexibility ranging from complete viewer control (true video-on-demand), to complete service provider control (traditional broadcast TV). We first describe our proposed Jukebox paradigm and relate it to other on-demand paradigms. We also describe several critical research issues, including the one-to-many delivery of content, program scheduling policies, server location, and the provision of advanced services like VCR-style interactivity and advanced reservations. In addition, we present our implementation of a Jukebox-based service called the Interactive Multimedia Jukebox (IMJ). The IMJ provides scheduling via the World Wide Web (WWW) and content delivery via the Multicast Backbone (MBone). For the IMJ, we present usage statistics collected during the past couple of years. Furthermore, using this data and a simulation environment, we show that Jukebox systems have the potential to scale to very large numbers of viewers.

the interactive multimedia Jukebox imj a new paradigm for the on demand delivery of audio video
Computer Networks, 1998Co-Authors: Kevin C Almeroth, Mostafa H AmmarAbstract:Abstract Straightforward, one-way delivery of video programming through television sets has existed for many decades. In the 1980s, new services like Pay-Per-View and Video-on-Demand were touted as the “killer application” for next-generation Internet and TV services. However, the hype has quickly died away leaving only hard technical problems and costly systems. As an alternative, and what we propose, is a new paradigm offering flexibility in how programs are requested and scheduled for playout, ranging from complete viewer control (true VoD), to complete service provider control (traditional broadcast or cable TV). In this paper, we describe our proposed Jukebox paradigm and relate it to other on-demand paradigms. Our new paradigm presents some challenges of its own, including how to best schedule viewer requests, how to provide VCR-style interactive functions, and how to track viewer usage patterns. In addition to addressing these issues we also present our implementation of a Jukebox-based service called the Interactive Multimedia Jukebox (IMJ). The IMJ provides scheduling via the World Wide Web (WWW) and content delivery via the Multicast Backbone (MBone). We discuss the challenges of building a functioning system and our ongoing efforts to improve the Jukebox paradigm.

a log stuctured organization for tertiary storage
International Conference on Data Engineering, 1996Co-Authors: D.a. Ford, J MyllymakiAbstract:We present the design of a log-structured tertiary storage (LTS) system. The advantage of this approach is that it allows the system to hide the details of Jukebox robotics and media characteristics behind a uniform, random-access, block-oriented interface. It also allows the system to avoid media mount operations for writes, giving a write performance similar to that of secondary storage.

jukola democratic music choice in a public space
Designing Interactive Systems, 2004Co-Authors: Kenton Ohara, Matthew Lipson, Marcel Jansen, Axel Unger, Huw Jeffries, Peter MacerAbstract:Jukola is an interactive MP3 Jukebox device designed to allow a group of people in a public space to democratically choose the music being played. A public display is used to nominate songs which are subsequently voted on by people in the bar using networked wireless handheld devices. Local bands and artists can also upload their own MP3s to the device over the Web. The paper presents a field trial of the system in a local cafe bar. As well as the value in affording a democratic musical outcome, more importantly the whole process of voting and choice created a rich source of social value and interaction in the form of discussions around music, playful competition, identity management and sense of community.

information Jukebox a semi public device for presenting multimedia information content
Ubiquitous Computing, 2003Co-Authors: Wolfgang Strauss, Monika Fleischmann, Jochen Denzinger, Christoph GroenegressAbstract:The Information Jukebox is a digital enquiry kiosk aimed at browsing media files. It combines a novel gesture-based and hands-free interface with an expressive graphical user interface and an attractive physical design. The system was developed within the context of a media arts exhibition and thus had to meet both functional and semiotic requirements. Unlike comparable systems it offers a complete and playful solution for browsing media.
