In recent days, the number of users having multiple devices according to time and places continue to increases with the help of wide spreading plurality of mobile devices. Consequently, the need for a user to share a media content on his/her multiple devices; furthermore, this movement brings the expansion of N-screen service focusing on connectivity, mobility, and integrity. N-screen service is platform that mediates the use of content or services on multiple devices with the continuous playing scheme. However, N-screen services have the problem of being provided exclusively by a service provider. This paper aims to implement a continuous playing scheme based on RESTfull and on an open service platform; the prototype was successfully implemented on the Android - PC environment.

Streaming Technology can support the real-time playback without downloading and storing multimedia data in local HDD. So, client browser or plug-in can represent multimedia data before the end of file transmission using streaming technology. Recently, the demand for efficient real-time playback and transmission of large amounts of multimedia data is growing rapidly. But most users' connections over network are not fast and stable enough to download large chunks of multimedia data. In this paper, we propose an intelligent IP streaming system based on personalized media service. The proposed IP streaming system enables users to get an intelligent recommendation of multimedia contents based on the user preference information stored on the streaming server or the home media server. The supposed intelligent IP streaming system consists of Server Metadata Agent, Pumping Server, Contents Storage Server, Client Metadata Agent and Streaming Player. And in order to implement the personalized media service, the user information, user preference information and client device information are managed under database concept. Moreover, users are assured of seamless access of streamed content event if they switch to another client device by implementing streaming system based on user identification and device information. We evaluate our approach with manufacturing home server system and simulation results.

In this paper, we present a service model which serves multimedia contents to end consumer(End-user) that have various mobile communication terminals under a communication & broadcasting converged environment that broadcasting and communication networks are linked. A main feature of this service model is that it has a distribution structure that deliver to end consumer via adaptation of content from production of contents offering End to End (E2E) media QoS and personalized contents consumption. The proposed service model may be used as a reference model for distribution of multimedia content in communication & broadcasting converged environment in the future.

IPTV services, as the convergence service of communication and broadcasting, are regarded as the essential information communication media in the New Economy era by providing the consumers with various services through the collaboration among communications, broadcasting and many of other media service providers. The research starts with recognition that, in the new media era, where communication and broadcasting are converging, there are endless demands for new services and various contents, which are driving forces behind the business model of IPTV. In other words, the research expected that customer satisfaction and purchase intention would be different according to the service quality(contents). It was expected that the difference of the perceived service quality(contents) could cause the difference of the process of adopting new technologies. The study on how consumers are satisfied with services provided, and which factors of the service quality have a more significant effect on consumer satisfaction will provide very valuable information for forecasting future trends in the IPTV market. The research tried to investigate factors which influence on consumer satisfaction and loyalty through an empirical survey with real users of IPTV services. Based on the results, the research suggested effective ways of diffusing IPTV.

Social Media is the open online tool and media platform for sharing and participation of users opinion, experience, viewpoiont, so general situation that is one-side flowing from production to consume doesn't act, and while use of two-way, user create contents use of sharing and participation. This social media include Blog, Social Network Service(SNS), Wiki, User Create Contents(UCC), Micro Blog, 5 types. In broad terms, Social Learning is self-learning that user sharing with coperation and collective intelligence through Social Media, and in few wards Social Learning is learning for Social Media. In this research, we define Social Media and Social Learning, and research of method of use of Elementary Education.

In multi-media, multi-channel era, video viewing using various digital devices via the Internet, not the existing broadcasting network, is emerging as a new broadcasting viewing behavior. OTT service is regarded as the main service of this change of viewing behavior. It is a video service that can seamlessly use any content desired by the user at any time, at any time, any device, any contents, if the Internet connection is available. The purpose of this study is to investigate the factors affecting the satisfaction of OTT service by applying the technology acceptance model (TAM). As a result of analyzing through 303 questionnaires of the early users of OTT service, social pressure, perceived popularity, perceived cost, user reputation, individual innovation, and esthetics set as external factors in this study are partially affects perceived usefulness, perceived ease of use, and perceived enjoyment. In addition, perceived usefulness, ease of use, and enjoyment are directly influencing satisfaction. Based on these results, we discuss the theoretical and practical implications and propose future research direction.

Many countless services form using the Internet technology of things, in order to provide a variety of services in the current also many institutions, have created a new technology and protocols. In this paper, we design the resource service model for the efficient service provided by the system for controlling access to the Internet services of the things, to implement. The resources of the service that the user tries to access modeled using LCRS (Left Child-Right Sibling) tree, by utilizing the service token resource, it is possible to perform access control to services.

Previous U-Commerce researches have dealt with the business support systems for traditional commerce space such as real world shopping malls. This paper investigates U-Commerce business models in service space. The McDonald's Touch-Order case is analyzed from business model perspective and the Media-Embedded Place business model is introduced as a U-Commerce business model for value creation in service space. The media-embedded place business model attaches auto-identification tags to tables or billboards, triggers commercial transaction through the tags, and shares the revenues and the incentives among the place owners and commerce/content providers. This paper analyzes its scenario and applications and illustrates the profitability analysis using so-called 'tag evaluation model'.

Currently, various technological models and services are emerging because of the development of information and communication technology and the convergence of industries. The ICT car field is expanding because of technological convergence in the automobile industry. However, ICT convergence services are still being developed based solely on technology; characterization of users and their needs is lacking. Therefore, two types of ICT car services that apply human-centered design processes are developed in this study. These processes create services and models while considering the quality and functions of products based on users (instead of technology) when developing products or services. Usability evaluation was performed on the developed services; a human-centered design process was applied to the results to confirm that the derived services resulted in high satisfaction. In the future, these research results will provide useful applications when developing ICT car services and strategies.
