Motivated by the Communication Broadcasting Convergence service, various technical approaches are being used to develop more efficient antenna models. This paper proposes a compact mobile antenna which is attachable to a cell phone and is applicable for Communication Broadcasting Convergence. In the design of the antennas for mobile handsets, size reduction is a crucial factor. In this paper, the compactness of a loop antenna is realized by bending a folded-dipole. A short planar dipole is transformed to a twice folded dipole and a loop antenna to produce a larger input resistance. The current distribution of the antenna is the same as a loop antenna, and its radiation patterns are omni-directional. We also analyze the performance of the RFID antenna by exploring the current-induced near field radiation patterns using a electro-optic field mapping system.

최근 IT(Information Technology)와 타(他)산업 간의 융 복합이 촉진되면서 새로운 융합서비스로 사물지능 통신(M2M, Machine to Machine)이 차세대 지능형 인프라 기반의 핵심 서비스로 부각되고 있다. 사물지능 통신은 기존의 통신 인프라를 활용하여 사물정보의 수집, 가공, 처리를 통해 최종 서비스를 제공하는 기술 분야로 PHY, MAC, 라우팅에 대한 기술 이슈보다는 서비스 관점에서의 네트워크 아키텍처 정의와 기능, 서비스 플랫폼 간의 연동, M2M 단말과 네트워크 간의 인터페이스에 대한 연구가 진행 중이다. 본 논문에서는 사물지능통신 융합서비스를 사용자에게 보다 편리하게 제공하기 위한 기존 플랫폼 간의 연동을 위한 요구사항과 방안을 제안한다.

It has been developed to calculate fuel budget for a geostationary communication and broadcasting satellite. It is quite essential that the pre-launch fuel budget estimation must account for the deterministic transfer and drift orbit maneuver requirements. After on-station, the calculation of satellite lifetime should be based on the estimation of remaining fuel and assessment of actual performance. These estimations step from the proper algorithms to produce the prediction of satellite lifetime. This paper concentrates on the fuel estimation method that was studied for calculation of the propellant budget by using the given algorithms. Applications of this method are discussed for a communication and broadcasting satellite.

The era of convergence is being applied to all areas of Information and Communication Technology (ICT). The convergence of broadcasting service and communication service almost occurs on smart devices including smartphone. The smart hybrid Digital Multimedia Broadcasting (DMB) is a typical example of the convergence of broadcasting and wireless communication service. The hybrid mobile broadcasting service can support seamless video, 3D, high quality, and additional data services based on network connection between the broadcasting and wireless network. The gateway and terminal (including apps on the smartphone) take the role of the main components on the hybrid service. This paper presents the service concept, main components structure, the implementation of gateway and terminals, and field test to the urban areas for the mobile hybrid system.

The user-centric broadcasting environment includes the agent system and personalized broadcasting services for user-adaptive TV watching. In this paper, we propose broadcasting environment consisting of personalized broadcasting services and a multi-agent broadcasting system for the services. The proposed system employs the intelligent agent technology of the Foundation for Intelligent Physical Agents (FIPA) as well as metadata technology of MPEG-7 and TV-Anytime Forum (TVAF). To verify the usefulness of the proposed environment, we implemented a test-bed and demonstrated the proposed agent system with three services including intelligent user-information management service, information mobility service, and content retrieval service.

In the 21st century, broadcasting, communication, and computer have been integrated due to the development of digital technology. Accordingly, to overcome the limit of respective communication media and to maintain them, their independent area shall not be classified. This study is to examine the future environment of digital TV broadcasting, to analyze customizing type service and interactive type TV technology, and to make asymmetric interactive digital TV publication broadcasting system, which is TV broadcasting in the next generation to treat visual image, sound, and various data all together by harmonizing broadcasting and communication like ISDB(Integrate Service Digital Broadcasting). In addition, to develop service on publication broadcasting with high quality, this study is to propose to develop relative devices for TV/PC reception to realize a new communication type TV publication broadcasting, by analyzing technology for producing, sending, transmitting, receiving, and saving to apply to customizing type interactive system and by examining its application.

This study is conducted to achieve following two purposes. First, this study investigates domestic conditions and problems of data broadcasting industry. Second, this study suggests the improving way of the legal and administrative systems in order to promote domestic data broadcasting industry. Survey was conducted with 16 companies and a few business men for gaining data of general condition and analyzing problems about domestic data broadcasting industry. The results are as follow: first, domestic industry was suffering from the lack of man power, finance, and the delay of data broadcasting service schedule. Second, respondents argued there was no the legal basis and the systematic regulation under the current digital broadcasting policy of government. To resolve those problems, this paper proposed the making laws preparing for the fusion service of communication and broadcasting, systematic assistance of government, the way of technology development and technical standardization, and the way of constructing infrastructure and cultivating man power.

A radiation analysis is performed for the Ka and Ku-band transponder of the Communications and Broadcasting Satellite (CBS) that is planned for launch into the geo-synchronous orbit. A particular attention is given to calculation of Total Ionizing Dose (TID) for the mission life time of 15 + 3 years. A numerical modeling of the charged particles at the geo-synchronous orbit is undertaken. The charged particles from the modeling are then transported through the mechanical structure and component housings of the transponder. A set of locations are selected for the detailed calculation of TID. The results from the present calculation show that three-dimensional modeling of the component housings as well as the mechanical structure of the spacecraft is requisite in order to acquire a reliable calculation of TID.
