In this paper, we first presents the challenges in social-aware video delivery. Then, we present a principal framework for data-driven social video delivery approaches.  ...  The Internet has recently witnessed the convergence of online social network services and online video services: users import videos from content sharing sites, and propagate them along the social connections  ...  Video popularity is a key factor in designing and optimizing video delivery systems, and the change thus has strong implications.  ...

An anatomy of a YouTube meme

Limor Shifman
2011 New Media & Society  
In its concluding section, the article addresses the skyrocketing popularity of mimicking in contemporary digital culture, linking it to economic, social and cultural logics of participation.  ...  Drawing on YouTube popularity-measurements and on user-generated playlists, a corpus of 30 prominent memetic videos was assembled.  ...  Such ads often result in many user-generated imitations (see, for instance, Cadbury's eyebrows advertisement, available at http://www.youtube.com/ watch?v=TVblWq3tDwY).  ...

On Improving the Performance Dependability of Unstructured P2P Systems via Replication [chapter]

Anirban Mondal, Yi Lifu, Masaru Kitsuregawa
2004 Lecture Notes in Computer Science  
The ever-increasing popularity of peer-to-peer (P2P) systems provides a strong motivation for designing a dependable P2P system.  ...  This paper looks at dependability from the viewpoint of system performance and aims at enhancing the dependability of unstructured P2P systems via dynamic replication, while taking into account the disproportionately  ...  To address dynamically changing popularities of files in P2P systems, each peer checks the number of accesses N k (for recent time intervals) for each data file replicated at itself and deletes files,  ...

Probabilistic assignment of movies to storage devices in a video-on-demand system [chapter]

T. D. C. Little, D. Venkatesh
1994 Lecture Notes in Computer Science  
A video-on-demand server must satisfy a large customer base and a diverse archive of movies under changing movie popularity and daily load peaks.  ...  Our approach uses a probabilistic model of movie popularity in data distribution and replication to balance user requests with available disk I/O bandwidth.  ...  We assume that a daily computation of the popularity distribution is sufficient to track its dynamics.  ...

Exploring the Optimal Replication Strategy in P2P-VoD Systems: Characterization and Evaluation

Weijie Wu, John C.S. Lui
2012 IEEE Transactions on Parallel and Distributed Systems  
We address two fundamental issues: (a) what is the optimal replication ratio of a movie if we know its popularity, and (b) how to achieve these optimal ratios in a distributed and dynamic fashion.  ...  We first formally show how movie popularities can impact server's workload, and formulate the video replication as an optimization problem.  ...  Each video file is divided into small pieces called chunks. When a peer joins the system, a local tracker recommends it a set of other peers for downloading its required chunks.  ...

Peer-Assisted Media Streaming: A Holistic Review [chapter]

Yuan Feng, Baochun Li
2010 Studies in Computational Intelligence  
We approach this task by first presenting design objectives of streaming systems in general, and then discuss differences between live and on-demand streaming.  ...  These common and different design objectives motivate the protocol design space in streaming systems, in categories of peer selection, segment scheduling, and distributed caching protocols.  ...  The common way of doing so is to use number of requests for a specific video content to represent its popularity and the number of replicas in the system to reflect its availability.  ...
