    Unleashing the Power of Edge-Cloud Generative AI in Mobile Networks: A Survey of AIGC Services

    Full text link
    Artificial Intelligence-Generated Content (AIGC) is an automated method for generating, manipulating, and modifying valuable and diverse data using AI algorithms creatively. This survey paper focuses on the deployment of AIGC applications, e.g., ChatGPT and Dall-E, at mobile edge networks, namely mobile AIGC networks, that provide personalized and customized AIGC services in real time while maintaining user privacy. We begin by introducing the background and fundamentals of generative models and the lifecycle of AIGC services at mobile AIGC networks, which includes data collection, training, finetuning, inference, and product management. We then discuss the collaborative cloud-edge-mobile infrastructure and technologies required to support AIGC services and enable users to access AIGC at mobile edge networks. Furthermore, we explore AIGCdriven creative applications and use cases for mobile AIGC networks. Additionally, we discuss the implementation, security, and privacy challenges of deploying mobile AIGC networks. Finally, we highlight some future research directions and open issues for the full realization of mobile AIGC networks

    Technical analysis of content placement algorithms for content delivery network in cloud

    Content placement algorithm is an integral part of the cloud-based content de-livery network. They are responsible for selecting a precise content to be re-posited over the surrogate servers distributed over a geographical region. Although various works are being already carried out in this sector, there are loopholes connected to most of the work, which doesn't have much disclosure. It is already known that quality of service, quality of experience, and the cost is always an essential objective targeting to be improved in existing work. Still, there are various other aspects and underlying reasons which are equally important from the design aspect. Therefore, this paper contributes towards reviewing the existing approaches of content placement algorithm over cloud-based content delivery network targeting to explore open-end re-search issues

    Changing Business Models in the Creative Industries: The cases of Televison, Computer Games and Music Executive Summary

    This research examines the business model response to the change from analogue to digital in the creative industries. Looking at both traditional and emerging business models, the project focuses on three sectors: television, computer games and music. A series of six case studies, two from each sector, provide illustrative cases of the business model response to challenges to enforcement of copyright and the advent of digital technologies. This paper reports on the findings of qualitative research into business models comprising six case studies from 25 semi-structured interviews, participant observation and literature sources. The research incorporates a literature review to establish the business model methodology and analyse the current state of research. The research findings show that the creative industries are in a state of business model experimentation and that the roles of intermediaries are changing. Furthermore, the evidence suggests that the Intellectual Property (IP) framework may be secondary to other influences on business model

    Video delivery networks : challenges, solutions and future directions

    Get PDF
    Internet video ecosystems are faced with the increasing requirements in versatile applications, ubiquitous consumption and freedom of creation and sharing, in which the user experience for high-quality services has become more and more important. Internet is also under tremendous pressure due to the exponential growth in video consumption. Video providers have been using content delivery networks (CDNs) to deliver high-quality video services. However, the new features in video generation and consumption require CDN to address the scalability, quality of service and flexibility challenges. As a result, we need to rethink future CDN for sustainable video delivery. To this end, we give an overview for the Internet video ecosystem evolution. We survey the existing video delivery solutions from the perspective of economic relationships, algorithms, mechanisms and architectures. At the end of the article, we propose a data-driven information plane for video delivery network as the future direction and discuss two case studies to demonstrate its necessity

    A Survey on ChatGPT: AI-Generated Contents, Challenges, and Solutions

    Full text link
    With the widespread use of large artificial intelligence (AI) models such as ChatGPT, AI-generated content (AIGC) has garnered increasing attention and is leading a paradigm shift in content creation and knowledge representation. AIGC uses generative large AI algorithms to assist or replace humans in creating massive, high-quality, and human-like content at a faster pace and lower cost, based on user-provided prompts. Despite the recent significant progress in AIGC, security, privacy, ethical, and legal challenges still need to be addressed. This paper presents an in-depth survey of working principles, security and privacy threats, state-of-the-art solutions, and future challenges of the AIGC paradigm. Specifically, we first explore the enabling technologies, general architecture of AIGC, and discuss its working modes and key characteristics. Then, we investigate the taxonomy of security and privacy threats to AIGC and highlight the ethical and societal implications of GPT and AIGC technologies. Furthermore, we review the state-of-the-art AIGC watermarking approaches for regulatable AIGC paradigms regarding the AIGC model and its produced content. Finally, we identify future challenges and open research directions related to AIGC.Comment: 20 pages, 6 figures, 4 table

    An Empirical Investigation Of Information Technology Mediated Customer Services In China

    Information technology mediated customer service is a reality of the 21st century. More and more companies have moved their customer services from in store and in person to online through computer or mobile devices. Using 208 respondents collected from two Chinese universities, this paper investigates customer preference over two service delivery model (either in store or online) on five type of purchasing (retail, eating-out, banking, travel and entertainment) and their perception difference in customer service quality between those two delivery model. Results show that a majority of Chinese students prefer in store and in person for eating out. For ordering tickets for travel and entertainment, they prefer computer/mobile device. For retail purchasing and banking, less than half of the students prefer in person services. In general, the results show that ordering through computer/mobile devices has become more popular in China and has received higher rating for most of customer service quality except security compared to ordering in store. In addition, it is found that there exist a gender difference in purchasing preference and perception in service delivery quality in China

    The potential of machine mediation in the maintenance of public service media

    Get PDF
    This production study argues predictive analytics (PA) and behavioral targeting (BT) will be useful for public service media (PSM). Whereas PA is the offering of digital content based on personal data, previous browsing behaviors, and user preferences, BT is the nuanced matching of content to audience segments. The topic is of critical importance for leaders of PSM, for media regulators and for audiences. The study draws on network and new media theory to provide context. The rationale for the study is the urgent need for PSM to begin using advanced digital production processes as mediation by machine is giving commercial digital firms a market advantage. An alternative PSM approach would benefit the quality of the public sphere. The use of PA and BT is considered in four cases: the websites of The Guardian and the BBC in the UK, and The Washington Post and CNN in the USA
