This paper describes a digital convergence platform(DCP) which is implemented based on the MPEG-21 multimedia framework. DCP is a newly proposed solution in this research for the convergence service of future home multimedia environment. DCP is a common platform designed to have the feature of reconfigurability, by means of S/W. which supports to run diverse digital multimedia services. A distributed peer to peer service and transaction model is also a new feature realized in DCP using the MPEG-21 multimedia framework. A prototype DCP is implemented to verify its functions of multimedia service and transactions. The developed DCPs are networked with IP clustering storage systems for the distributed service of multimedia. Successful streaming services of the MPEG-2/4 video and audio are verified with the implemented test-bed system of DCP.

During earthquake, the safety control plane at home is very important to prepare the turnover and falling accident of furniture as a disaster measures. But a lot of people might not have knowledge and education on the safety control plane at home such as the fixing of furniture. Therefore, in this study, the test application of iPhone was developed to enlighten and educate them using the smart phone. Through this application, residents, furniture store employees, moving service workers, builders and etc. will be able to understand the safety control plane at home.

The purpose of this study was to investigate the enforcement strategy for Consumer Service marketing of an e-Commerce shopping mall. An e-CRM for a Cosmetic e-Commerce shopping mall, Data Warehousing(DW) component, analysis of data mining of the DW, and web applications and strategies had to developed for marketing of consumer service satisfaction. The major findings were as follows: An RFM analysis was used for consumer classification, which is a fundamental process of e-CRM application. The components of the DW were web sales data and consumer data fields. The visual process of consumer segmentations (superior consumer class) for e-CRM solutions is presented. The association analysis algorithm of data mining to up-selling and cross-selling indicates an association rule. These e-CRM results apply web DB marketing and operating principles to a shopping mall. Therefore, the system applications of e-CRM to Consumer services indicate a marketing strategy for consumer-oriented management.

국내 홈 네트워크 시장은 여러 업체가 컨소시엄을 구성하여 시범지역을 확대하는 등 점차 보편화 되어가고 그 응용 범위를 확대해 나가는 단계에 있다. 하지만 홈 네트워크 시장의 서비스 및 제품들을 사용하는 사용자들이나 기획 / 개발하는 개발자들이 실제로 체감하는 홈 네트워크 시장의 활성화 정도는 아직 부족한 면이 있다. 홈 네트워크 시장의 활성화 정도가 부족한 원인에는 여러 가지 문제점들이 있지만 그러한 문제점 가운데에는 홈 네트워크 시장의 주 구성원인 사용자와 개발자가 가지고 있는 문제점에 대한 서로간의 관점 차이로 인한 부분도 있을 것이다. 본 연구에서는 홈 네트워크 제품 및 서비스 사용자와 개발자 인터뷰를 통해 문제점을 조사하고 이에 대한 관점의 차이를 분석하고자 하였다. 구체적 문제점 파악을 위해 개발자 관점에서의 개발 프로세스는 '기획, 개발, 판매, 유지보수'의 단계로, 사용자 관점에서의 사용 프로세스는 '구매, 설치, 사용, 이전, AS, 폐기'의 단계로 구분하여 조사하였다. 문제점의 비교를 위해 개발 프로세스와 사용 프로세스를 하나의 제품 및 서비스 라이프사이클로 통합 정의하였고, '판매, 유지보수 / 구매, 설치, 사용, 이전, AS, 폐기' 단계에서 공통된 영역을 찾을 수 있었다. 이 영역에서 사용자와 개발자의 문제점 비교를 통해 두 그룹간의 관점의 차이를 도출하여 각 단계별 홈 네트워크 문제점에 대한 관점의 차이를 확인할 수 있었다.

Smart phone environment have an effect on consumer life style, as well as advances in technology. In this paradigm shift on digital convergence make change to commodities, services, and distribution channels for consumers. HomePlus wholesale that is representative distribution company in Korea launched the new distribution channel model that combined off-line store with online store and mobile shopping system called 'smart mobile virtual store'. That is highly praised by abroad media and festivals. This study is an exploratory study on consumer-centric smart mobile virtual store of HomePlus. There are value and chance for developing the new digital distribution model, in this study, because the case study and evaluation of consumers is important in this momentous time.

Bluetooth is the wireless solution which lay emphasis on Short Range, Low Power, Low Cost using a 2.4GHz frequency hopping. And the wireless interface of digital machinery and the various application studies, which are based on that, is making progress lively. This paper provides "Ethernet Connection for Bluetooth Piconet". Ethernet Connection is usually used in our life and can make the Connection of Internet for Bluetooth Piconet. Therefore, this system forms the basis of "Home or Office Remote Control System".

For the usage of the different standard technology among DRM vendors, the DRM technologies in today could not guarantee the interoperability between the digital contents and digital devices. While users have been guaranteed the protection of contents, they have to put up with the limitation and inconvenience. The Superdistribution methods that InterTrust has proposed is the content distribution technology which is possible to use the content only by the user authentication with the license regardless of the acquisition of the DRM contents. However, it need a additional license with re-authentication from DRM server when the original contents need to be moved to other devices from the own device. In this paper, to reduce the inconveniences of re-authentication and re-issue procedures of the license and continually to protect the rights of contents on the offline, we propose the DRM system that creates domain between home devices and enable users to freely transfer contents with the domain.

As smart phones are becoming popular, an operating system is being used at wearable devices, home appliances and smart TVs. A user is able to use various applications on devices with operating system, but there is an increased threat of hacker. Thus, the technology for detecting the forgery of applications is becoming more important on operating system. To detect the forgery of the application, a digital signature technology is used on the filed of application digital signature. According to W3C recommendation, the signing process of application digital signature must be performed at least twice, and the applications which are signed by the application digital signature have to be validated for all signature files when the application is installed in the operating system. Hence, the performance of the application digital signature validation system is closely related to the installer performance on the operating system. Existing validation system has performance degradation due to redundancy of integrity verification among application components. This research was conducted to improve the performance of the application digital signature validation system. The proposal of validation system which is applied proxy system shows a performance improvement compared to the existing verification system.

These days many DLNA home media network services start in home network area. DLNA networking softwares included in DLNA media devices contains all of server, renderer and controller functions. But a home media device in home media network environment not uses all of DLNA functions but uses only limited functions. Using all of integrated DLNA functions wastes networking and processing resources especially in home media network, because a home media device uses very limited functions. For example, a smart-TV has a main role of playback and a network attached storage has a main role of media content storage. In this paper, we analyze integrated DLNA networking softwares and design DLNA software models representing each home media device so as to utilize device resources efficiently. And we implement DLNA softwares for smart-TV and smart-phone and test resource efficiency.
