    Popular videos are often clicked by a mount of users in a short period. With content recommendation, the popular contents could be broadcast to the potential users in wireless network, to save huge transmitting resource. In this paper, the contents propagation model is analyzed due to users' historical behavior, location, and the converging properties in wireless data transmission, with the users' communication log in the Chinese commercial cellular network. And a recommendation scheme is proposed to achieve high energy efficiency.Comment: 6 pages.

    Six emerging trends in media and communications - occasional paper

    This paper examines six emerging trends in media and communications, which highlight that consumers are increasingly using personalised access pathways to communications and content services that cut across different networks, devices and services. Introduction The ACMA monitors industry and consumer data to identify changes in the media and communications environment and their impact on regulatory settings. Previous ACMA research, such as Broken concepts1 and the Emerging issues2 series of papers, has identified areas of regulatory strain resulting from changes in this environment. The ACMA’s 2014 data collection program highlighted six further trends that are of particular interest as they indicate challenges to the regulatory frameworks within which the ACMA works. These trends illustrate how developments in communications device technologies and over-the-top (OTT) services and content offer both: new opportunities for businesses and individuals as consumers and citizens potential challenges to confident and optimal use of these new services. The evolving media and communications environment offers new ways to understand and achieve policy objectives, and may expose alternatives to ’black-letter’ regulation. However, changes in media and communications can also strain the effectiveness and efficiency of existing regulatory settings designed in an environment where content and communication services have been delivered by network owners over dedicated networks and devices. The selected trends highlight that consumers are increasingly using personalised access pathways to communications and content services that cut across different networks, devices and services. This paper looks at the implications of these six trends for existing regulatory settings

    The Datafication of Public Service Media Dreams, Dilemmas and Practical Problems:A Case Study of the Implementation of Personalized Recommendations at the Danish Public Service Media ‘DR’

    Historically, public service broadcasting had no quantifiable knowledge about audiences, nor a great interest in knowing them. Today, the competitive logic of the media markets encourage public service media (PSM) organizations to increase datafication. In this paper we examine how a PSM organization interprets the classic public service obligations of creating societal cohesion and diversity in the new world of key performance indicators, business rules and algorithmic parameters.The paper presents a case study of the implementation of a personalization system for the video on demand service of the Danish PSM ‘DR’. Our empirical findings, based on longitudinal in-depth interviewing, indicate a long and difficult process of datafication of PSM, shaped by both the organizational path dependencies of broadcasting production and the expectations of public service broadcasting

    Children\u27s content regulation and the \u27obesity epidemic\u27

    Full text link
    Some 30 years ago, Australia introduced the Children\u27s Television Standards (CTS) with the twin goals of providing children with high-quality local programs and offering some protection from the perceived harms of television. The most recent review of the CTS occurred in the context of a decade of increasing international concern at rising levels of overweight and obesity, especially in very young children. Overlapping regulatory jurisdictions and co-regulatory frameworks complicate the process of addressing pressing issues of child health, while rapid changes to the media ecology have both extended the amount of programming for children and increased the economic challenges for producers. Our article begins with an overview of the conceptual shifts in priorities articulated in the CTS over time. Using the 2007-09 Review of the CTS as a case study, it then examines the role of research and stakeholder discourses in the CTS review process and critiques the effectiveness of existing regulatory regimes, both in providing access to dedicated children\u27s content and in addressing the problem of escalating obesity levels in the population

    Cooperating broadcast and cellular conditional access system for digital television

    This thesis was submitted for the degree of Doctor of Philosophy and awarded by Brunel University.The lack of interoperability between Pay‐TV service providers and a horizontally integrated business transaction model have compromised the competition in the Pay‐TV market. In addition, the lack of interactivity with customers has resulted in high churn rate and improper security measures have contributed into considerable business loss. These issues are the main cause of high operational costs and subscription fees in the Pay‐TV systems. This paper presents a novel end‐to‐end system architecture for Pay‐TV systems cooperating mobile and broadcasting technologies. It provides a cost‐effective, scalable, dynamic and secure access control mechanism supporting converged services and new business opportunities in Pay‐TV systems. It enhances interactivity, security and potentially reduces customer attrition and operational cost. In this platform, service providers can effectively interact with their customers, personalise their services and adopt appropriate security measures. It breaks up the rigid relationship between a viewer and set‐top box as imposed by traditional conditional access systems, thus, a viewer can fully enjoy his entitlements via an arbitrary set‐top box. Having thoroughly considered state‐of‐the‐art technologies currently being used across the world, the thesis highlights novel use cases and presents the full design and implementation aspects of the system. The design section is enriched by providing possible security structures supported thereby. A business collaboration structure is proposed, followed by a reference model for implementing the system. Finally, the security architectures are analysed to propose the best architecture on the basis of security, complexity and set‐top box production cost criteria

    Rural telecommunications policy reform

    This publication summarises the issues and points to possible changes in rural telecommunications policy. The purpose was not to revisit the usual arguments about the cost of the universal service obligation, or the comparison between metropolitan areas and remote areas. It simply aims to draw together clear thinking about the issues, in the hope of a better outcome for users and providers of telecommunications
