This study investigates whether the use of N-screen service affects the use of Home TV service as a supplement or substitution. In this study, we collected 132 available survey answers from CJ Hellovision Tving users. We found supplement relationship between Tving and Home TV, which implies that the more use in Tving service, the use of Home TV increases as much as 36.4%. From the result, some meaningful implications were derived. First, a direction for content price negotiation between N-screen providers and terrestrial broadcasters can be suggested. Second, the result will provide a suggestion for establishing a competitive strategy between N-screen providers and Pay-TV providers. Third, this study may solve copyright dispute between content providers and pay TV operators.

In this paper, we propose proposed mobile wagering platform technology, where the buying lottery contents registered in secure storage through lottery technology can be used as a common experience in smartphones, smart pads, and PCs, etc. Currently, many people are producing and consuming various types of contents in bulk, and it is expected that real-time contents and old contents coexist as IoT(Internet of Things) technology is commonly deployed in the future. Therefore, we need to develop a differentiated service that can compete with global services in lottery contents authoring and collaboration systems to create new markets. Accordingly, we implemented an wagering service platform to occupy cloud markets with high quality lottery contents produced through collaboration.

N스크린 서비스는 하나의 디지털 컨텐츠를 TV, 스마트폰, 태블릿 PC나 노트북 등을 통해 일관성 있는 문맥으로 단절 없이 소비할 수 있는 환경을 마련해 준다. 현재 이 서비스는 TV와 모바일 기기의 스마트화, 클라우드 컴퓨팅의 확산, 홈 네트워킹의 발전, 모바일 웹을 위한 다양한 기술의 발전으로 그 발전 가능성이 매우 큰 서비스이다. 이런 N스크린 서비스는 단순한 연속적 상연 서비스를 넘어 다양한 기기를 동시에 사용하는 협업적 N스크린 서비스로도 진화할 것이다. 이런 환경에서 개발된 SK Planet hoppin 서비스는 TV, PC, 스마트폰, 태블릿 PC간의 연동을 통해, 기기 종류에 제약 없이 구매된 컨텐츠를 상영할 수 있는 통합 미디어를 구현하기 위해 개발되었다. 이를 위해 통신망으로 연결된 미디어 서버 및 hoppin 단말기를 위한 안드로이드 기반의 플랫폼을 개발하였으며, 크래들을 사용한 TV 연결을 통해 모바일 기기를 secondary 스크린으로도 사용될 수 있도록 했다. 이런 서비스는 현재 국내 유일의 형태이며 hoppin은 향후 협업적인 N스크린 서비스로 더욱 발전해 갈 수 있을 것이다.

Due to the high digital technology, various devices such as TV, PC, smartphone, and pad computer are connected to each other using internet and under the circumstance internet services of which the running platforms are mainly PC become "N-screenlized" by extending their service platform to non-PC devices. As a digital TV has outstanding features of being the most influential device in the living room and having the wide spectrum of users, several internet services has been ported on the digital TV platform (in the form of data services) in order to enhance their brand powers. Most of the services, however, failed to get a satisfactory results as the data services are defeated by the broadcasting contents in the competition for the viewer's interests. In the paper, the design guidelines that make data services not to compete with the broadcasting contents are proposed and a prototype of a data service that accommodates the guidelines is introduced. The prototype, called "TV ideal-type world-cup", does not disturb a viewer's watching broadcast contents and channel-changing behavior while it is running and its service flow is designed for a viewer to achieve the goal of service in a few minutes so that the viewer can enjoy the service in a commercial period.

In this paper, content management system (CMS) is introduced to serve IPTV, WEB, Mobile, Smart Devices and others using a single content management system's transcoding engine to overcome the limitations of traditional content management systems. Developed CMS reduced the burden of content management by automatically recognizing one content into several content simultaneously to provide the best content to each device, thereby reducing the burden of CMS additional adoption. The focus is on utilizing automated system for studio content and automatic management of mobile filmed images, and it is planned to develop the One-Stop Service for contents by adding functions for contents production later.

Recently the research convenient for the user interface for the user interface technology that can be applied to the UI according to user's choice being made. To this end, the W3C is underway in a variety of devices from N-Screen service, consistent service delivery and the user's preferences according to UI to support adaptive services for a variety of research environments. In this paper, we studied the basic model-based user interface technology to develop a UI for the user's convenience. Web application applications apply measures will be used to apply the technology acquisition, and next-generation Web applications.

Recently, there is study about interface for user convince. this users interface technology can apply to UI depend on user choice. For that, W3C study various technology which is N-screen service on different device, provide consistent service, and UI adjust service depends on user preference. Therefore, we need UI study based on this model and standard technology. In this paper, study UI technology based on basic model to develop UI for user's convenience. So it can be useful to apply next-generation Web applications and secure web-application measure plans.

방송 환경과 인터넷 환경이 융합되고 스마트 TV의 등장에 따라, 사용자는 복잡한 미디어 서비스 환경에 노출되었다. 이로 인해 사용자가 접하는 미디어 콘텐츠의 종류와 데이터의 양은 기하급수 적으로 증가 하고 있다. 웹과 인터넷을 기반으로 하는 정보기술은 모바일 전자 기술의 발달에 따라 데스크탑 이라는 공간적인 한계를 벗어나 유기적인 유비쿼터스 환경으로 변화하고 있으며, 정보 및 콘텐츠의 개념은 웹문서와 텍스트를 넘어서 UCC, 음악, 영화 등의 모바일 멀티미디어 콘텐츠들로까지 빠르게 확장되고 있다. 또한, N-스크린과 IPTV 서비스의 등장은 사용자로 하여금 장소와 시간에 관계없이 미디어를 취득할 수 있는 이득을 제공할 수 있으나 사용자가 선택은 더욱 힘들어 졌다. 방송 통신 융합 단말에서 콘텐츠에 대한 정보를 제공 받기 위해서는 TV-Anytime 인터페이스, MPEG Query Format 인터페이스, OPEN API 등이 사용 가능하다. TV-Anytime 인터페이스는 대용량 저장 장치를 갖는 방송 단말기에서 메타데이터를 제공 및 검색하기 위한 인터페이스를 제공하며, MPEG Query Format 인터페이스는 MPEG-7을 기반으로 하는 메타데이터를 검색하기 위한 인터페이스를 제공한다. 또한, OPEN API는 업체들을 중심으로 공개적으로 제공 되어지는 API로 개방과 참여를 목적으로 한다. 이에 본 논문에서는 사용자의 콘텐츠 사용 정보를 바탕으로 선호 정보를 생성하고, 이를 바탕으로 콘텐츠에 대해서 강화된 정보를 생성하기 위한 서비스를 설계 및 개발한다.

Multimedia Broadcast communication convergence services are broadcast communication convergence services new form that combines a platform technology for driving the application services of various media-related Internet and TV devices. It is possible to mounted the embedded OS of TV existing technology and to support a variety of smart application services to a TV technology evolved form equipped with various platforms on the OS. The services that are fused in this way, multi-media broadcasting communication convergence new services Open IPTV, Smart TV, mobile IPTV, and N-screen, are services actively focusing on three companies domestic services. However, in order to use the software to connect to the Internet for the provision of services, is inherent software vulnerabilities or the Internet. These vulnerabilities can lead to serious security incidents. Therefore, in this paper, or be able to derive the potential security threats that occur in multimedia broadcasting service environment based on security threats and vulnerabilities of existing threats lead to such security incidents in fact, the security it was carried out through a mock hacking validation for threats. It was also suggested necessary technical security measures that can be protect against security threats revealed by using the verification result through the penetration testing. Has been presented countermeasures in fusion communication service environment of multimedia broadcasting by using these results.
