Explicating user behavior toward multi-screen adoption and diffusion

PurposeThe purpose of this paper is to analyze user behavior toward multi-screen services by employing neural networks to predict overall customer satisfaction and to prioritize the factors that influence customer intentions.Design/methodology/approachMulti-screen experiences require a new approach incorporating multiple methods. A proposed multi-state analytic approach in which the research model is tested using structural equation modeling was utilized. The results were then used as inputs for a neural network model to predict multi-screen adoption.FindingsThe findings indicate that multi-screen quality significantly influences usability, which subsequently affects the adoption of the technology.Practical implicationsThe policy and managerial implications of multi-screen development are discussed based on the models of acceptance and diffusion.Social implicationsThe emergence of multi-screen services as well as the simultaneous and sequential engagement of users with multiple devices throughout the day challenges the ability of marketers to develop effective communication strategies.Originality/valueThis study provides an in-depth analysis and heuristic data regarding user drivers, market dynamics, and policy implications in the one-source multi-use ecosystem.

New MPEG Transport Standard for Next Generation Hybrid Broadcasting System With IP

MPEG-2 transport system (TS) and ISO base media file format (ISOBFF) standards developed by MPEG have been widely used by various industries and applications including digital broadcasting systems. Recently MPEG has developed a new standard, MPEG Media Transport or MMT, for next generation broadcasting system considering the emerging convergence of digital broadcasting network and the Internet. MMT assumes HTML5 and Internet protocol (IP) as deployment environment and inherits major features of MPEG-2 TS while simplifying unnecessary complicated features in IP environments. It also considers hybrid delivery of multi-screen services. MMT defines an application layer protocol enabling packetization of opaque objects or files without considering the structure of data and media processing unit (MPU) format specific packetization. Synchronization technology of MMT providing flexible synchronization of multimedia components delivered through hybrid environment over multiple devices is built on top of HTML5.

HTML5 기반 융합 서비스의 서비스이동 메커니즘 설계

최근, W3C에서는 웹을 통해 다양한 웹 응용을 제공할 수 있는 기능을 포함하는 HTML5의 표준화가 추진 중이다. 광대역 무선 네트워크의 등장 및 스마트 TV, 태블릿 PC, 스마트 폰과 같은 스마트 단말이 웹 브라우저를 탑재함에 따라 스마트 단말을 통해 언제 어디서나 웹 서비스를 이용하는 것이 가능해졌다. 또한 사용자가 다수의 단말을 보유함에 따라 상황에 맞는 단말을 사용하여 웹 응용을 이용하는 멀티스크린 서비스의 요구가 증가하고 있다. 본 논문에서는 HTML5 기반의 웹 플랫폼에서 웹 객체를 그룹화하는 방안, 이동할 웹 객체의 정보를 추출하는 방안 및 다른 단말로부터 전달받은 웹 객체 정보를 기반으로 새로운 객체를 생성하는 방안을 제안한다. 또한 HTML5 기반 개방형 웹 플랫폼에서 단말 간 웹 응용을 이동하는 웹 서비스 이동 구조를 제안하였으며 이를 구현하여 테스트용 웹 문서와 일반 웹 문서에 대해 크롬 확장기능을 이용하여 검증하였다. 마지막으로 node.js와 웹 소켓을 이용하여 단말 간 객체 정보를 전달하는 메커니즘을 구현하고 제안한 방안을 검증하였다. Recently, the W3C has developed the HTML5 standard which gives the basis for providing various web applications on the web environments. Because of the advent of the smart devices and the broadband wireless network, users can accesse the web applications on the smart devices at anytime and anywhere. In addition, the demand on the multiscreen services, which enables users to use the appropriate device to their situation, has increased, since users have various smart devices. In this paper, we propose the grouping mechanism of web objects on the HTML5 based web platform, the extraction mechanism of the web object information which is used to create the web object on other devices, and the web object creation mechanism based on the received web object information. In addition, we propose the web service migration architecture between devices on the open web platform and implement the grouping, extraction and creation mechanism of the web objects on the test web document and generic web document with Chrome extension. Finally, we implement the delivery mechanism of the web object information between devices using the node.js and the WebSocket technologies.

Research for Standards of N-Screen Service Platform for Smart Public Services

Smartphone (smartpad) and cloud computing has grown rapidly. So, the users started getting interested in multi-screen services. However, various OS / platforms due to the increased content development time and cost. Increase the cost of content development for a multi-screen service, it has been an obstacle. To solve this problem in this study, HTML5-based multi-screen service platform standards specification was established. HTML5 is a specification of the next generation of Web standards. Standards specification established by this study were research in terms of the service provider. And, this standards specification can be used independently of the service infrastructure and device. In addition, this standards specification in order to develop a multi-screen services are efficient and easy to use. For verification adequacy of standards specification established in this study, Scenarios technical entries were mapped by standard specification entries.
