For practical multimedia streaming services in home networks, seamless binding between two stream formats (Digital Video(DV) and MPEG-4), on two heterogeneous protocols (IEEE1394 and Ethernet), is required. IEEE1394 is the best way for the real-time transmission of high bandwidth Audio/Video(A/V) content inside a home, and Ethernet provides a connection to anywhere, not only in homes, but also outside by using wired or wireless mobile solutions, however, because of differences between the two stream solutions (DV-IEEE1394 and MPEG-4-Ethernet), an appropriate device or function is needed between the two parts. In this paper, the software and hardware architecture of a media gateway are suggested in order to solve the problems. First, hardware architecture was designed to support transcoding functions between DV and MPEG-4 in real-time. It also solves resource limitations between two protocols and related devices such as bandwidth and quality factors. Suggested software architecture coordinates the heterogeneity of transaction management and addressing mechanisms between two protocols. Based on the design requirements of the proposed system, we implemented a prototype media gateway based on the proposed architecture and the performance was evaluates being successful.

Quality controlled gateway CISMeF provides such services for health resources. However, the human cost of maintaining and updating the catalogue are increasingly high. This paper presents the automatic indexing system currently developed in the CISMeF team to be used as such for preliminary indexing, or after human reviewing for the final indexing. The system architecture, using the INTEX platform for MeSH term extraction is detailed. The results of a first evaluation tend to indicate that the automatic indexing strategy is relevant, as it achieves a precision comparable to that of other existing operational systems. Moreover, the system presented in this paper retrieves keyword/qualifier pairs as opposed to single terms, therefore providing a significantly more precise indexing. Further development and tests will be carried out in order to improve the coverage of the dictionaries, and validate the efficiency of the system in the indexers' everyday work.

Subject gateways enable various online users to efficiently use the Internet. Subject gateways allow access to a quality controlled collection of Internet resources. It also enables users to browse the collection by subject. In creating subject gateways, the European Union's DESIRE Project recommends the use of standard formats to make subject gateways compatible with other gateways and bibliographic databases.

EasyNet was conceived as a gateway system to enable end users without searching experience to use online text systems. When the system began in 1987, it was partially sponsored by the National Federation of Abstracting and Indexing Services. Parent company Telebase Systems Inc soon began to offer versions of the service through remarketers, such as EasyLink and CompuServe. By 1993, a user could access over 850 online data bases. Although EasyNet was originally meant for the end user; it has developed into a useful tool for expert searchers., When EasyNet appeared on the commercial market in late 1984, it sparked the interest of occasional online database users and novice, but inquisitive, searchers. Many expert searchers, however, were convinced [...]

The so-called Main Gate is a single box that links energy management and electric utilities with video-on-demand, the Internet, broadband pipes, cable and telecommunications. Residential gateways are in the testing stage, with homes being wired up and video feeds, fax machines and modems being added. The MainGate System developed by Scientific-Atlanta, which is said to be the first two-way home energy-management system, may pave the way for additional communications systems., The Main Gate: It's the entryway from the public switched network into the multiple networks that reside within a house. In concept, it's a single box linking electric utilities and [...]
