In this thesis propose a conceptual design of a platform for better home entertainment experience. Smart phone, smart TV and a personal computer are the most important devices in this platform design. The platform was designed and proposed by a personal computer. The platform provides a high degree of interaction and integration among devices within the environment. The clouds are better than the traditional approaches and it is more acceptable in terms of security and economy.

1999 년부터 상용화된 무선 인터넷 서비스는 국내의 경우 이동통신 3 사가 각기 독자적인 통신 기법 및 서비스 체제를 가지고 있었다. 이로 인하여 서로 다른 이동통신사의 무선 단말기 플랫폼들은 상호 호환성(interoperability)이 없었다. 이러한 비호환성은 단말기 제조업체나 컨텐츠 제작 업체에게 기술적인 어려움은 물론이고 비용적인 측면에서 여러 가지 문제점을 낳았다. 이러한 문제점을 해결하고자 2002 년부터 WIPI(Wireless Internet Platform for Interoperability)라는 표준화된 무선 인터넷 플랫폼의 개발이 시작되어 현재는 WIPI 2.0 을 탑재한 무선 단말기가 출시된 상황이다. 본 논문에서는 WIPI 플랫폼이 탑재된 무선 단말기가 유료화된 컨텐츠를 다운로드 하여 사용할 수 있도록 해주는 다운로드 시스템의 설계 및 구현에 대해서 기술한다. 이를 위해 컨텐츠 다운로드 프로토콜, 최적화된 컨텐츠의 결정기법, 그리고 COD(Compile On Demand)를 이용한 네이티브 코드 적용 기법에 대해 설명한다.

In order for end-users in home networks to receive opportunities for useful services that go beyond legacy Internet Protocol TV (IPTV) services, this paper proposes a service platform that resides on the residential gateway (RG) for interworking between the home network and IPTV. This proposed service platform is called the home-oriented IPTV service platform (HISP) on the RG (HISP-RG). The proposed HISP-RG provides open architecture and functionalities to enable 3rd party IPTV service providers to locally and directly deliver home-oriented IPTV services to end-users in home networks. The HISP-RG can be an "add-on" and not a "built-in" solution for the existing standard RG. This paper introduces several home-oriented IPTV services that can be executed and delivered locally through the HISP-RG. Then, the open architecture and functionalities of the HISP-RG are defined and their requirements are specified. Finally, use cases of the HISP-RG for home-oriented IPTV services are presented.

This paper presents a novel method to design and implement mobile u-health system by defining the essential elements of mobile healthcare services. We choose common service elements for the proposed u-healthcare scheme and design the service platform. Especially we focus on automatic feces or urine sensing u-care scheme to prove the effectiveness of our platform. We construct the system with sensing part with a manikin and a diaper wireless communication part with feces or urine sensing data, and coordinator system based on the u-health platform defined in this paper. Experimental results show that our scheme is useful in the area of u-care service for the handicapped, the elderly, and patients who can hardly move by themselves. In addition the designed scheme offers a realized u-care scheme with the purpose of advanced developing tools for application or service developers.

In this paper, the implementation of creative engineering robot with MCU platform is described. This robot, as a platform of robot system to be used as creative engineering education, has to satisfy restrictions in many aspects in order to study algorithm and apply for the processor based function and pattern recognition application. Considering many restrictions of the mobile platform for creative robot system, we made this robot autonomous by using efficiently the LINUX embedded system. And we choose Marvell Monahan processor(PXA320) as MCU flatform, and used CentOS5.2 as an embedded OS that has the function of robustness and optimality. For flexibility and modularity, the platform has expansion ports. The results of experiment are described to show the pattern matching of creative engineering mobile robot with LINUX programming environments.

The existing fixed telematics facilities for car were restricting of efficiency, utilization, communication, possibility, so it become disconnected with reality in the domestic and foreign market within thy near future, like as the case of 'car-phone'. It is too difficult to make a various business model on the restrict basis. To solve these problems, We suggested Tablet PC system as a new mobile telematics platform. The telematics platform based on the Tablet PC realize the perfect office, because it shows an excellent portability, high power and extension, various input equipment, and environment of communication in the car. To realize this concreteness, it needs a proper marketing strategy for a new business model. For this purpose, We analyzed the structure of industry, selected a proper target market, and established the strategy of marketing. Additionally, We proposed new business models ; particularly Portal site, Car-Home network, Car Software Tuning, and T-Vaccine(Intelligent Car Inspection System). These are made possible by the only Tablet PC platform.

The structure of $IP^2$(IP based-IMT Network Platform) as ubiquitous platform is three-layered model : Middleware including NCPF(Network Control Platform) and SSPF(Service Support Platform), IP-BB(IP-Backbone), Access network including Sensor network. A mobility management(MM) architecture in NCPF is proposed for $IP^2$. It manages routing information and location information separately. The existing method of multicast control in $IP^2$ is Remote Subscription. But Remote Subscription has problem that should be reconstructed whole Multicast tree when sender moves. To solve this problem, we propose a way to put Multicast Manager in NCPF.
