Since home network system is usually set up based on the built-in system inside home at the time of construction, it has a difficulty in being compatible with new devices after construction. In this paper, we propose DBS(Dynamic Binding System) that can make links effectively among the devices located in inside and outside of home networks. Implementation of the DBS is based on the ZigBee's binding in WPAN(Wireless Personal Area Network). For this research, we constructed the system consisting of home server that contains proxy server and location server, devices inside home in which tinyOS is embedded, and mobile device that is an emulator. The communication inside home is done by IEEE 802.15.4 protocol and the communication between servers and mobile devices outside home is done by TCP/IP protocol. Regardless of device's address format, the DBS facilitates a link among the devices located inside and outside of home networks. And, introducing a new device into home network can be recognized easily by exchanging messages between devices.

The need for a unified data communication for home digital devices and realtime multimedia services in home network has led to recent research on home gateway over the broadcasting and communication convergence network. In this paper, we discuss requirement for such home gateway design and define services that the home gateway provides. Then, we propose a home gateway architecture aimed to efficient multimedia distribution for heterogeneous devices in the home network. The proposed home gateway has a role of protocol gateway, media server, and media trans-coder. Finally, we show the feasibility of the proposed home gateway in several multimedia distribution scenario.

In this paper, we take advantage of the SEN Remote HMI App as a tool based on Raspberry Pi server for the smart home control. This is a smart home control system built in an open and a low-cost Raspberry Pi as a server, and take advantage of Android-based graphical programming software SEN Remote HMI. If you build it based system expansion and additional works interface via the Raspberry Pi and Arduino, it is expected to be extended to the Internet of Things (IoT) enabling environment for the implementation of smart home.

In this paper, we propose speech interlace using VoiceXML in home network system Existing home network uses Bluetooth, IrDA, wireless LAN and Home RF but these was able to use a long distance such as outdoors or these was difficult to using method. The proposing VoiceXML speech interlace is supported with home network services more than other interface technology in a long distance also speech interlace controls home server using a wire and a wireless phone and is informed of problems to direct calling for user through VoiceXML server. In this paper, such speech interlace is able to use the aspect of home network and supports to practical remote gauge examination, remote control services. And on the basic of that, we evaluate efficiency of purposed method.

In this paper, a video broadcasting system between a home-server-type device and a mobile device is proposed. The home-server-type device can automatically extract semantic information from video contents, such as news, a soccer match, and a baseball game. The indexing results are utilized to convert the original video contents to a digested or arranged format. From the mobile device, a user can make recording requests to the home-server-type devices and can then watch and navigate recorded video contents in a digested form. The novelty of this study is the actual implementation of the proposed system by combining the actual IT environment that is available with indexing algorithms. The implementation of the system is demonstrated along with experimental results of the automatic video indexing algorithms. The overall performance of the developed system is compared with existing state-of-the-art personal video recording products.

유비쿼터스 환경에서 스마트 객체에 부착되는 RFID 태그에는 스마트 객체를 유일하게 식별하기 위한 식별자 만이 저장되고 객체의 상세 정보는 별도의 정보 서버에 분산 저장 및 관리가 된다. 이와 같이 분산되어 있는 정보를 사용하기 위해서는 사용자가 일일이 정보 서버의 위치를 알아 내고, 각 정보 서버로부터 필요한 정보를 얻어 와야 하는 문제가 발생한다. 본 논문에서는 여러 정보 서버에 분산 저장되어 있는 다양한 종류의 객체 정보를 실시간으로 통합하여 사용자에게 제공하고, 또한 객체 정보의 유형 및 특성에 따라 카탈로그 검색, 소유권 변화, 포함 관계 변화, 추적 등의 스마트 객체에 특화된 질의 기능을 제공하기 위한 스마트 객체 정보 통합을 위한 미들웨어의 설계 내용을 소개한다.

Due to the advancements in the capabilities of smart devices and home networks, we are able to easily access multimedia contents stored in a home server. In this paper, we present a wireless media content sharing mechanism for home networks that utilizes UPnP-based DLNA technology. We also present a novel Peer-to-Peer content sharing system that is able to operate on the client as well as server. Our system supports multiple push/pull services simultaneously via a multi-thread technique, and our intuitive user interface facilitates ease of use. Future studies would explore the feasibility of implementing our system in a multi-hop environment or providing a community-wide service.

In this paper, we proposed and designed a novel SNA protocol which operates in the way of a server and a client in the power control system. The proposed SNA protocol includes the information about the mode switching, the saving position of context information, the user trigger, and so forth, which are needed in the power management devices. We consider the application of the SNA protocol to the home network, where message flows between the SNA server and the SNA client. To verify the operation of the SNA protocol, the state transition diagrams of the server in the home gateway and the client in the network device are shown. Hence, we can conclude the SNA can operate without malfuction.

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.
