Crowdsourced Live Streaming over the Cloud

Empowered by today's rich tools for media generation and distribution, and the convenient Internet access, crowdsourced streaming generalizes the single-source streaming paradigm by including massive contributors for a video channel. It calls a joint optimization along the path from crowdsourcers, through streaming servers, to the end-users to minimize the overall latency. The dynamics of the video sources, together with the globalized request demands and the high computation demand from each sourcer, make crowdsourced live streaming challenging even with powerful support from modern cloud computing. In this paper, we present a generic framework that facilitates a cost-effective cloud service for crowdsourced live streaming. Through adaptively leasing, the cloud servers can be provisioned in a fine granularity to accommodate geo-distributed video crowdsourcers. We present an optimal solution to deal with service migration among cloud instances of diverse lease prices. It also addresses the location impact to the streaming quality. To understand the performance of the proposed strategies in the realworld, we have built a prototype system running over the planetlab and the Amazon/Microsoft Cloud. Our extensive experiments demonstrate that the effectiveness of our solution in terms of deployment cost and streaming quality

A Web-based IPTV Content Syndication System for Personalized Content Guide

In this paper, we propose a web-based content syndication system in which users can easily choose IPTV contents. This system generates personalized content guide to provide a list of IPTV contents with respect to user’s interests and statistics information of their online social community. For this, IPTV contents and relevant metadata are collected from various sources and transformed. Then the service and content metadata are processed by user metadata including audience measurement and community metadata. The metadata flows are separated from content flows of transport network. The implementation of IPTV content syndication system demonstrates how to arrange IPTV contents efficiently from content providers to the end user’s screen. We also show that the user metadata including online community information are important for the system’s performance and the user’s satisfaction

Retrospective Study of Healthcare Resources Developed for Patients by Interprofessional Teams

Wayne State University (WSU) emphasizes the importance of interdisciplinary education by having students participate in an Interprofessional Team Visit (IPTV) program. A 60-minute virtual visit is conducted to assess adults aged over 50 years within the Detroit Metropolitan Area (Metro Detroit) community. This project was designed to prepare healthcare students in evaluating the mental, physical, and social health aspects of assigned patients based on specific disciplinary assessments. Upon completion of assessments, the interdisciplinary team provided the patient with resources based on the team and the patient\u27s agreed-upon area of concern. Twenty-eight IPTV teams, consisting of a medical and occupational therapy student and a healthcare professional student from another discipline studying at WSU, were randomly created. The IPTV resource guides created by each team were reviewed and sorted into two categories based on the health or social need of the individual patient. The data identified three main areas of interest, which included medication management, diet and exercise plans, and the use of technology to stay connected to medical professionals, friends, and family. The purpose of this report is to assess the IPTV program’s findings and analyze patients’ concerns based on health or social needs and the resources presented to them

Developing sustainable business models for institutions’ provision of open educational resources: Learning from OpenLearn users’ motivations and experiences

Universities across the globe have, for some time, been exploring the possibilities for achieving public benefit and generating business and visibility through releasing and sharing open educational resources (OER). Many have written about the need to develop sustainable and profitable business models around the production and release of OER. Downes (2006), for example, has questioned the financial sustainability of OER production at scale. Many of the proposed business models focus on OER’s value in generating revenue and detractors of OER have questioned whether they are in competition with formal education. This paper reports on a study intended to broaden the conversation about OER business models to consider the motivations and experiences of OER users as the basis for making a better informed decision about whether OER and formal learning are competitive or complementary with each other. The study focused on OpenLearn - the Open University’s (OU) web-based platform for OER, which hosts hundreds of online courses and videos and is accessed by over 3,000,000 users a year. A large scale survey and follow-up interviews with OpenLearn users worldwide revealed that university provided OER can offer learners a bridge to formal education, allowing them to try out a subject before registering on a formal course and to build confidence in their abilities as learners. In addition, it was found that using OER during formal paid-for study can improve learners’ performance and self-reliance, leading to increased retention and satisfaction with the learning experience

Open educational resources for all? Comparing user motivations and characteristics across The Open University’s iTunes U channel and OpenLearn platform.

With the rise in access to mobile multimedia devices, educational institutions have exploited the iTunes U platform as an additional channel to provide free educational resources with the aim of profile-raising and breaking down barriers to education. For those prepared to invest in content preparation, it is possible to produce interactive, portable material that can be made available globally. Commentators have questioned both the financial implications for platform-specific content production, and the availability of devices for learners to access it (Osborne, 2012). The Open University (OU) makes its free educational resources available on iTunes U and via its web-based open educational resources (OER) platform, OpenLearn. The OU’s OER on iTunes U reached the 60 million download mark in 2013; its OpenLearn platform boasts 27 million unique visitors since 2006. This paper reports the results of a large-scale study of users of the OU’s iTunes U channel and OpenLearn platform. A survey of several thousand users revealed key differences in demographics between those accessing OER via the web and via iTunes U. In addition, the data allowed comparison between three groups: formal learners, informal learners and educators. The study raises questions about whether university-provided OER meet the needs of users and makes recommendations for how content can be modified to suit their needs. As the publishing of OER becomes core to business, we reflect on reasons why understanding users’ motivations and demographics is vital, allowing for needs-led resource provision and content that is adapted to best achieve learner satisfaction, and to deliver institutions’ social mission

Utilization of Flow Concept for Digital Service Requirements Prioritization

We argue that the concept of flow can be useful in investigating how requirements for digital services can be analyzed. We apply Novak et al\u27s (2000) framework to analyze how flow can be utilized for requirements prioritization for digital services. Our findings indicate that the flow can be very useful for requirements development. Furthermore, the findings show that the flow can be potentially used for understanding experiential- and task-oriented user activities. Therefore, we conclude that the flow should be considered as a service requirements prioritization metric not only for digital services dominated by hedonic utility needs by users, but with all digital services. This calls for further research in service requirements method development and on how flow impacts user experience

Co-opetition of TV broadcasters in online video markets : a winning strategy?

This article focuses on TV broadcasters adopting co-opetition strategies for launching online video services. It is claimed that the emergence of online video platforms like YouTube and Netflix is driving TV broadcasters to collaborate with their closest competitors to reduce costs and reach the necessary scale in the global marketplace. The article sheds light on online video platforms that were developed following a co-opetition strategy (Hulu and YouView). The establishment of joint ventures in online video, however, has been scrutinised by competition authorities which fear that collaboration between close competitors lessens rivalry and reduces consumer choice. Therefore, several co-opetition projects (among others BBC’s Kangaroo and Germany’s Gold) have been prohibited by competition authorities
