In this paper, we design and implement the UHSNS-DRM(Ubi-Home Smart Multimedia Streaming-Digital Right Management) in Ubi-Home. The proposed system support flexible distribution platform for digital content copyright protection and management in Ubi-Home. This system also can provide multimedia streaming service to authorized users who are using PC, STB, PDA, and Portable Device, etc. Furthermore, we adopt concept of domain authentication and it help to improve the efficiency of license management for all devices in Ubi-Home. We design user's location recognition algorithm in order to provide intelligent services. Of course, this algorithm is applied for the proposed system. Start after striking space key 2 times.

In multimedia service of Ubiquitous Home Environment(UHE), the requirements such as intelligent service that is executed automatically without direct order of user and fitted service compatible for each user and comfortable of user, interoperability of multimedia contents between incompatible devices will increase. Multimedia protection and management, authentication and authority administration methods that are suitable for above demands are also required. In this paper, we suggest authentication method suited for UHE and propose user oriented multimedia service(UHMS: Ubiquitous Home Multimedia Service) that provides the interoperability of multimedia between incompatible devices, conducts intelligently the context information (preference information, device information etc.) using sensor module and home server, provides and secure services.

A purpose of this study is to develop multimedia materials of “Technology and Home Economics” subject matter in a national level. Researchers. writers. examiners. deliverers and developers in order to develop multimedia materials were organized of us with 40 People. First. we analyzed the textbooks of "Technology $.$ Home Economics" subject matter and made the idea design Second we got storyboards based on the idea design. Finally. we developed the 1021 multimedia materials based with storyboards. The developed materials were uploaded to the Edunet website. If the materials developed in this study are utilized. students of middle school will be get easily educational motive. and teachers are able to use the multimedia materials to the Technology $.$ Home Economics 1" subject instruction.

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.

Due to the miniaturization and the network supporting functions of home appliances, there is growing need for mobile environment home network system which provides flexibility, mobility and convenience to users. However in home, there are obstacles which make shaded areas and only static and restricted services are available for the existing mobile environment home network system. In this paper, we proposed the mobile environment home network system using Home Robot in order to solve the problem of existing mobile environment home network system.

Deploying advanced home networking technologies and modern home-networked devices in residential environments provides a playground for new home applications and services. Because home multimedia entertainment is among the most essential home applications, this paper presents an appealing home media content sharing scenario: home-networked devices can discover neighboring devices and share local media content, as well as enormous amounts of Internet media content in a convenient and networked manner. This ideal scenario differs from traditional usages that merely offer local media content and require tedious manual operations of connection setup and file transfer among various devices. To achieve this goal, this study proposes a proxy gateway architecture for home multimedia content distribution. The proposed architecture integrates several functional mechanisms, including UPnP-based device discovery, home gateway, Internet media provision, and in-home media content delivery. This design addresses several inherent limitations of device heterogeneity and network interoperability on home and public networks, and allows diverse home-networked devices to play media content in an identical and networked manner. Prototypical implementation of the proposed proxy gateway architecture develops a proof-of-concept software, integrating a BitTorrent peer-to-peer client, a UPnP protocol stack, and a UPnP AV media server, as well as media distribution and management components on the OSGi home gateway platform. Practical demonstration shows the proposed design and scenario realization, offering users an unlimited volume of media content for home multimedia entertainment.

These days, home network connects all home appliances using one of broadband convergence network, is constructed and propagated to more than 10 million house hold. Users can monitor and control statuses of home appliances using mobile terminal through homeserver. For active propagation of home network, high-quality multimedia service is very important. Specially, as digital recorder and digital camera is propagated, new paradigm that private DVDs can be shared in many household shows up. The homeserver is the main part of UbiHome, which can store much multimedia content and through which the user can search and share these contents. For searching and sharing, the metadata of contents is supposed to keep the consistency. These metadata include the description to different format such as Image, movie, and music. Therefore, we intend to provide a RDF model for effectively storing, searching and managing high-quality contents in UbiHome. In this paper, we propose to make Ontology to close semantic approach using RDF/RDF Schema for managing multimedia data in UbiHome. we propose RDF-Based Local Ontology and merging these ontology to RDF-Based Global Ontology.

This paper explains a system that is suitable for detecting software error for multimedia distance education based on home network environment. This system consists of an ED, and ES. ED is an agent that detects an error by hooking techniques for multimedia distance education based on home network environment. ES is an agent that is an error sharing system for multimedia distance education based on home network environment. From the perspective of multimedia collaborative environment, an error application becomes another interactive presentation error is shared with participants engaged in a cooperative work.

A home network is a typical ubiquitous computing network that consists of various consumer devices and service environments. Home networks are requiring increasingly more complicated services, such as multimedia home theater and the monitoring and controlling of heterogeneous devices. Accordingly, a mutually connecting mechanism is needed among heterogeneous devices and services redundant. The current paper presents a Multimedia Room Bridge Adapter (MRBA) system that is designed to manage heterogeneous devices and support various services. In addition, a hardware and software prototype is implemented based on the proposed architecture.

On-going convergence between broadcasting and communication is currently bringing in lots of drastic changes to multimedia services to the home. The FTTH-based home networks will be the interface among the digital home appliances for broadcast digital contents as weil as for broadband data connection. In this paper, we discuss several design issues for home gateway architecture that effectively distributes realtime broadcasting contents (from either the headend in the access network or the satellite/terrestrial broadcasts) to heterogeneous devices in the home network.
