AthenaCloud: A cloud-based platform for multi-device educational software generation

Nowadays, information technologies play an important role in education. In education, mobile and TV applications can be considered a support tool in the teaching - learning process, however, relevant and appropriate mobile and TV applications are not always available; teachers can only judge applications by reviews or anecdotes instead of testing them. These reasons lead to the needs and benefits for creating one?s own mobile application for teaching and learning. In this work, we present a cloud-based platform for multi-device educational software generation (smartphones, tablets, Web, Android-based TV boxes, and smart TV devices) called AthenaCloud. It is important to mention that an open cloud-based platform allows teachers to create their own multi-device software by using a personal computer with Internet access. The goal of this platform is to provide a software tool to help educators upload their electronic contents - or use existing contents in an open repository - and package them in the desired setup file for one of the supported devices and operating systems.

Medical Students’ Challenges and Strategies in Producing Web TV Programs on YouTube

Cooperative learning occurs when students work together in small groups on an assigned project to achieve learning objectives. A classroom assignment given in an English for Specific Purposes course namely, Workplace Communication III, exposed medical students to this method. This assignment required students to produce a Web TV program and upload it to YouTube. In completing their assignment by employing cooperative learning method, the students applied several processes and faced challenges that eventually helped them to improve their communication skills in the English language. This study aimed to identify the challenges faced and the strategies the students employed to overcome those challenges. Seventeen first year medical undergraduates who enrolled in the Workplace Communication III course were involved in this study. Semi-structured focus group interviews and reflective notes were used to collect the data for this study. The challenges faced by students are time constraint, communication and technical difficulties, and a lack of creativity and confidence. The main strategies applied included brainstorming ideas, independent learning, and practices to overcome these challenges. This study could serve as a guideline for the course designers to improve the current course.

User centric content management system for open IPTV over SNS

Coupled schemes between service-oriented architecture (SOA) and Web 2.0 have recently been researched. Web-based content providers and telecommunications company (Telecom) based Internet protocol television (IPTV) providers have struggled against each other to accommodate more three-screen service subscribers. Since the advent of Web 2.0, more abundant reproduced content can be circulated. However, because according to increasing device's resolution and content formats IPTV providers transcode content in advance, network bandwidth, storage and operation costs for content management systems (CMSs) are wasted. In this paper, we present a user centric CMS for open IPTV, which integrates SOA and Web 2.0. Considering content popularity based on a Zipf-like distribution to solve these problems, we analyze the performance between the user centric CMS and the conventional Web syndication system for normalized costs. Based on the user centric CMS, we implement a social Web TV with device-aware function, which can aggregate, transcode, and deploy content over social networking service independently.

Predictive Relationship between Technology Acceptance Readiness and the Intention to Use Malaysian EduwebTV among Library and Media Teachers

Library and Media Teacher (LMT) serves as a catalyst for the implementation of the technology programs conducted in schools. The challenge to the LMT is to be more open and innovative to the innovations introduced in schools from time to time. Their level of readiness to accept new technology in teaching and learning earlier than their colleagues in schools could expedite the diffusion process into the school education system. Therefore, this study was conducted to measure the level of readiness acceptance among LMT in terms of Personal Innovativeness (PI), Personal Innovativeness Information Technology (PIIT) and Computer Self-Efficacy (CSE), and the contribution to the acceptance of Edu web TV in teaching and learning. The study involved 546 respondents consisting of LMT of primary and secondary schools in Malaysia. The findings show that the readiness acceptance level among LMT in terms of PI, PIIT and CSE are moderate. Significant relationships were found between CSE, PI, PIIT and behavioural intentions to use the Edu web TV. The obtained results also show that PIIT and CSE significantly contributed to the intention to use Edu web TV. Therefore, those individuals with higher levels of PIIT and CSE are more open, willing to try and confident in the adoption of new technology in teaching and learning than those with lower levels of PIIT and CSE. These results provide valuable feedback to institutions and educators in enhancing the effectiveness of LMT.

New Audience Message Absorption via Audio Visual Technology

The diversity of audio visual technology has its own effect to audience to obtain message through formal and informal education. Arguably, having acquired such ability, an individual will be able to absorb various media messages. This research seeks to redefine model of audience evolution that proposed by The Donald McGannon Communication Research Center of new audiences by adding an audio visual technology as a meaning-making components in the interpretation of portal web television. The concept of audio visual technology was further developed by adding conceptualization of meaning making in interpreting media messages. This research assumes that audio visual technology input can be exposed and the skills can be transferred to the respondent in a formal setting. The researcher seeks to identify the relevance of audio visual technology in raising the level and capacity of new audience absorbs message. The significance between the audio visual technology via the meaning-making components and the increasing level of new audience absorbs message. A total of 80 first-year media students from University Kebangsaan Malaysia were randomly selected to participate in the experiment. The students were divided into two respective groups, the treatment and the control. Only the treatment group was exposed to audio visual selected interactivity queues such as selected programs, comment, chat rooms and online quizzes. Both groups were later shown online portal web TV (tonton.com.my) that produced by Media Prima Group. The selection of this online portal web TV is justified in it being the first online TV portal that fixed in all Media Prima’s TV station. Findings from the experimental method discovered that students in both groups showed different levels of new audience absorbs message. Findings revealed that individual interpretation of the online portal web TV was dependent on time-binding factors such as experience, knowledge and education as well as the unique cultural conditioning of each individual. The findings of this study suggested that the audio visual technology meaning making component is the distinguishing element for model of audience evolution introduced by The Donald McGannon Communication Research Center in the absorbs message of the new audiences.

Improving IPTV Forwarding Masechanism in IEEE 802.16j MMR Networks Based on Aggregation

Internet protocol television (IPTV) service depends on the network quality of service (QoS) and bandwidth of the broadband service provider. IEEE 802.16j mobile multihop relay Worldwide Interoperability for Microwave Access networks have the opportunity to offer high bandwidth capacity by introducing relay stations. However, to actually satisfy QoS requirements for offering IPTV services (HDTV, SDTV, Web TV, and mobile TV) for heterogeneous users’ requests, providers must use a video server for each IPTV service type, which increases the network load, especially bandwidth consumption and forwarding time. In this paper, we present a solution for forwarding IPTV video streaming to diverse subscribers via an 802.16j broadband wireless access network. In particular, we propose a new multicast tree construction and aggregation mechanism based on the unique property of prime numbers. Performance evaluation results show that the proposed scheme reduces both bandwidth consumption and forwarding time.

A recommender system for the TV on the web: integrating unrated reviews and movie ratings

The activity of Social-TV viewers has grown considerably in the last few years--viewers are no longer passive elements. The Web has socially empowered the viewers in many new different ways, for example, viewers can now rate TV programs, comment them, and suggest TV shows to friends through Web sites. Some innovations have been exploring these new activities of viewers but we are still far from realizing the full potential of this new setting. For example, social interactions on the Web, such as comments and ratings in online forums, create valuable feedback about the targeted TV entertainment shows. In this paper, we address this last setting: a media recommendation algorithm that suggests recommendations based on users' ratings and unrated comments. In contrast to similar approaches that are only ratings-based, we propose the inclusion of sentiment knowledge in recommendations. This approach computes new media recommendations by merging media ratings and comments written by users about specific entertainment shows. This contrasts with existing recommendation methods that explore ratings and metadata but do not analyze what users have to say about particular media programs. In this paper, we argue that text comments are excellent indicators of user satisfaction. Sentiment analysis algorithms offer an analysis of the users' preferences in which the comments may not be associated with an explicit rating. Thus, this analysis will also have an impact on the popularity of a given media show. Thus, the recommendation algorithm--based on matrix factorization by Singular Value Decomposition--will consider both explicit ratings and the output of sentiment analysis algorithms to compute new recommendations. The implemented recommendation framework can be integrated on a Web TV system where users can view and comment entertainment media from a video-on-demand service. The recommendation framework was evaluated on two datasets from IMDb with 53,112 reviews (50 % unrated) and Amazon entertainment media with 698,210 reviews (26 % unrated). Recommendation results with ratings and the inferred preferences--based on the sentiment analysis algorithms--exhibited an improvement over the ratings only based recommendations. This result illustrates the potential of sentiment analysis of user comments in recommendation systems.

Book Review: Caveat Consumer: A User’s Manual to the News

Sunnyvale, CA: Unvarnished Press, 2012. 240 pp. $14.95 pbk. $9.95 Kindle.Here's something to chew on: is like food-you are what you eat.News stories, indeed most media messages, are designed to be as easy to swallow as warm honey, media critic John McManus writes in the second edition of Detecting Bull. language is simple. Articles are short. So are sentences. Images are dramatic. Key points are trumpeted in headlines and lead paragraphs. Why would anyone need help to figure out the news? The simple answer is that a great deal of what looks like news and factual information on the Web, cable and broadcast TV, the radio, even in newspapers, really isn't. Quality journalism is in more trouble than sobriety at a rugby party.McManus joins the scrum, showing how a diet high in Kardashians and low in fact checking and context is bad individuals and democratic society. With this update of Detecting Bull and a new book titled Don't Be Fooled, he offers a disturbing critique of today's media landscape and a guide seeking truth in a world of spin. Both books provide simple rules of thumb on how to detect BS (bald sophistry) in any medium- whether it's face-to-face or Facebook, Fox or NPR, Daily Kos or the Drudge Report.Learning to critically about news and information is essential, McManus says, what James Madison wrote with a goose quill in 1822 is as true as if it were Tweeted today: 'Knowledge will forever govern ignorance, and a people who mean to be their own governors, must arm themselves with the power knowledge gives.'This is familiar ground McManus, a former journalist and professor. In 1994, he published Market-Driven Journalism: Let the Citizen Beware?, which won a research award from the Society of Professional Journalists. So did the first edition of Detecting Bull in 2009. In between, McManus won grants and laurels establishing GradeTheNews. org, a sort of Consumer Reports of news media in the San Francisco Bay Area.His latest works are important additions in the field of media literacy because they combine theory and analysis with practical advice news consumers and professionals. Along the way, McManus quotes from such disparate voices as Lord Northcliffe, A. J. Liebling, and David Carr.Both books draw from the same material but present it differently. Detecting Bull is a textbook, with eleven scholarly but accessible chapters, each followed by exercises and discussion questions students, plus extensive footnotes.McManus begins with a chapter about the importance of critical thinking about news and information. He notes that as newsrooms have fired thousands of professional journalists, the web has exploded with often-bogus claims: News has never been so contested, so up-for-grabs. As a consequence, it has never been so difficult to discern what's reliable from the rest.McManus then explores the demise of mainstream news and the rise of competing narratives on issues such as climate change. While the scientific evidence of global warming is overwhelming, a growing number of Americans doubt the threat is real. McManus blames this in part on the fact that for the first time in history, we can fashion our own news diet, not some neutral editor. If we wish, we can tailor the news to our own biases.The book then discusses truthiness, a send-up about truth by faux journalist Stephen Colbert. On TV, Colbert deadpans that while truth is people who think with the heads, truthiness is those who know with their hearts. McManus writes, At the heart of Colbert's humor lies the incongruity of someone dressed in the authority of a dark suit speaking complete nonsense with absolute conviction. …

An inclusive approach to develop web TV applications

PurposeThis paper aims to present a brief overview of the European “Gentle User Interfaces for Elderly People” (GUIDE) project, which is creating a software framework and design tools that allow developers to efficiently integrate accessibility and personalisation features into their applications, minimizing intervention with existing development process and tools.

The project also contributes to develop standards for hybrid TV and the interoperable user model.Originality/valueThe GUIDE project is a first of its kind to take an end‐to‐end approach to accessible computing through presentations on user‐centred design, accessibility solutions, a software framework for industrial developers and standardization issues for legislators and regulators.

Design of an Alpine Skiing Game Using ActionScript 3.0

Flash is the most popular 2D animation and game development software, supporting vector and media technology at the core, which enables the development of small and pithy games. It is widely used in Web animation, courseware, TV commercials, game development, and other works of design. In this paper, we propose a control movement function and auxiliary functions for an alpine skiing game based on ActionScript 3.0. The control movement function is designed with moving phases (i.e., free fall, sliding, projectile, and landing). The auxiliary functions include drawing path, start/restart movement, and saving the highest score. In addition, for the visual design of our game, we designed animations in connection with a character and background. In order to facilitate testing the friction, users can input a chosen friction value. Without user input, the friction default is set at 0.97.

Virtual machine provisioning through satellite communications in federated Cloud environments

Cloud federation offers plenty of new services and business opportunities. However, many advanced services cannot be implemented in the real Cloud market due to several issues that have not been overcome yet. One of these concerns is the transfer of huge amount of data among federated Clouds. This paper aims to overcome such a limitation proposing an approach based on satellite communications. By comparing performance in data delivery on the Internet and satellite systems, it is evident that satellite technologies are enough ripe to be competitive against systems with a wired infrastructure. Thus, we propose to make use of satellite transmission to implement fast delivery of huge amount of data. Through the discussion of a use case, where a WEB TV company offers a streaming service, we show how to practically apply the proposed strategy in a real scenario, specifying the involvement of Cloud providers, Cloud users, satellite companies and end-user clients.

Multimedia, interactive and hypertextual features in divergent online news platforms: An exploratory study of Flemish online news

This paper argues for not studying the Web as one, homogeneous medium, but instead as a meta–medium that carries various divergent news media like news blogs, discussion forums, Web TV, and RSS news feeds, each with a specific presentation style. Based on a content analysis of Flemish online news media, the level of multimedia, interactivity and hypertext of different divergent news platforms are identified. Results suggest that multiple online platforms are used to present the news, even within meta–media like digital newspapers or portal sites. This analysis also reveals that the use of online news features varies among divergent news platforms, some being innovative and others rather traditional.

User Adoption Model under Service Competitive Market Structure for Next-Generation Media Services

As information technology rapidly develops and the period required to enter new technology shortens, there emerges a wide variety of alternatives for consumers. When there are many alternatives in the market, users choose after making comparisons. This process of making comparisons is our research key. We established a research model to find a mixed effect that comes from new attitudes to technology adoption and alternative’s continuous usage intention. The effect is revealed through a relative attractiveness (RA) factor to explain a user’s process of comparison. We empirically test our research model in the new media services, such as mobile TV, web TV, and mobile IPTV. According to our research results, a continuous usage intention of an existing technology is an important factor to explain the adoption of a new technology. So, the contribution of our research is in finding a role for the RA factor in research in new technology adoption.

Opportunities, restrictions, and challenges for Web TV in China

China has the most active Web TV business in the world. This study concerns Web TV based on peer-to-peer (P2P) streaming technology in China. Adopting the tripartite model of accessibility, content strategies, and revenue sources (ACR), we analyzed the business model of China's Web TV business. In the process of analysis, we surveyed the current situation of Web TV and the leading players. We also touched upon the policy environment, the behavior of Chinese consumers, and challenges from other media. The major findings of this study included: (a) in terms of accessibility, P2P technology was an advantage. However, given the variety of content and the increasing number of Web TV suppliers, P2P technology probably could lead to problems. (b) With regard to content strategies, although having diverse and rich content resources, every Web TV player in China has to face the challenge of content overlap and uniformity in the industry, and private players without their own branded content also need to solve the problem of illegal use of foreign content. (c) The most visible problem in obtaining revenue sources is that Web TV players in China depend too much on advertising with little payment from users and other sources. We suggest it is urgent for Web TV players to cultivate and acquire paid users for the sake of long-term development. We also found that the three factors of accessibility, content strategies, and revenue sources of the Web TV business were closely linked with and influenced each other. The competition between private Web TV ventures and state-owned Web TV suppliers and the impact on China's Web TV industry should be a focus.

Local communities on-line: mapping local Web-TVs in Italy

A wider spreading of broadband in Italy in recent years has led to the birth of many web-TVs originating from a variety of actors (educational institutions, public administrations, informal groups, etc.). A specific role is being played by local communities (neighborhoods, social centers, parishes, etc.) which, thanks to the on-line spreading of video content, can have their own TV channel to reach their members and promote themselves in global networks. This essay will map the distribution of these locally-originated web TVs in Italy investigating their ways of strengthening communication within the community and at the wider level of the global Internet network.
