Design issues of multi-beam satellite transponders have been actively studied. Multi-beam satellite transponders can be used in the first SS/TDMA system for satellite interactive multi-media services in Korea. To be used in SS/TDMA systems, a satellite transponder must have either base-band OBP(On-board Processor) or MSM(Microwave Switching Matrix) on-board switch those are capable to provide inter-connections to many earth stations in different beam coverages or different frequencies, i.e., Ka and Ku band. The use of MSM is considered proper due to a substantial developing cost and the required high techniques in base-band OBP. In this paper, we present a designed scheme of transponder being optimally suitable to the targeted SS/TDMA satellite systems, also analysis the performance.

Development of digital technology is advancing to levels which influence the formation of city landscapes and spaces. The use of media facade is creating modernized city-spaces with contemporary application of various digital mediums. In this way, media facade functions as media-art in an artistic point of view, while also providing the means for buildings to become landmarks in a city-scape point of view. Going a step further, media facade using interaction is drawing a lot of attention as it enables communication with the city inhabitants instead of one-way contents provision. This paper will research such interactive media facade using transparent display glass currently being used as construction building material and its potential growth.

Purpose of this study is to analyze the meaning of the hybrid digital culture and to find out the features of digital fashion shows appearing in the period of the hybrid digital culture as there have been almost no studies on the hybrid cultural values in the fashion shows and on the diachronic socio-cultural viewpoint of fashion show. The characteristics of hybrid digital culture were identified through the analysis of cases, and they were organized into three for this study; 'non-economic creativity', 'interactive communication' and 'transcendence'. Based on these characteristics, the features of hybrid digital cultures in the modern digital fashion shows were classified into the digitalization of presentation form and the acceptance by audience of digitalization using case studies. The features of digital fashion shows which appear through the presentation form in the digital fashion shows are as follows; 'Expansion of presentation media of runway' and 'Destruction of component factors of runway'. The features of digital fashion show in the perspective of audience's acceptance of digitalization are as follows; 'Audience's field experience through the live video', 'Participation by audience in interactive manner' and, 'Immersion in the virtual reality by the audiences'.

This study aims to identify the special features of high-concept funology observed in fashion products and expressional media by exploring funology in an era of high-concept, the emotional paradigm of the 21st century. High-concept funology in today's fashion can be explained as follows: First, 'virtual reality', which is often seen in fashion shows and fashion commercials, enhances consumer participation and involvement with blurred boundaries between the real world and the virtual world. With the expansion of various forms of real-time communication with consumers, positive images of the brand are being projected to the consumers. Second, 'form transformability', which is often found in fashion products, promotes customers' purchase desire as they are able to present themselves in a more versatile way in the fashion product that is changeable in various designs. Third, 'integration of different fields', which is easily found in various fashion goods, engages consumers in a mutual interaction under an entertaining setting with the product that is made to satisfy their needs attuned to their digital lifestyle. Fourth, 'interactive responsiveness', which is mainly recognized in fashion stores and commercials, is characterized by its interactive playfulness that encourages consumer participation through entertainment contents and promotes brand intimacy, eventually adding more value to its name.

The MPEG-4 standard is aimed to define an object based audiovisual coding standard to address the emerging needs from interactive broadcasting. Since a broadcasting program is created on the basis of its objects, it is considered that MPEG-4 is most suitable for interactive broadcasting contents production and it can be retrieved in terms of its properties. But, there is no system that protects the copyright of digital contents and manages copyright and possibility that contents producer and author's copyright receives infringement at process that exchange contents mutually rose very. Therefore, we need to control and distribute contents according to user's permission rights. In this paper, we present the authoring system based on MPEG-4 IPMP for copyright and protection of MPEG-4 contents. The main features of the proposed approach is to provide an MPEG-4 compliant IPMP authoring system in a plug-in type along with standardized interfaces, which is to be able to incorporated into an existing MPEG-4 content authoring system. In this way, it is capable of authoring content to the MP4 file format while accommodating protection and management of content in a unified way. Furthermore, it also allows a user to edit and/or author IPMP information in a more efficient way by offering form based user interfaces.

The scope ID field of IPv6 multicast address indicates the zone of the destination for which a multicast traffic is intended. Without any further examination on the header field, the scope ID enables a router to determine whether the traffic will be forwarded to a subnet or not. For the graceful migration from IPv4 networks to IPv6 networks, various IPv6 applications working through IPv4 networks are indispensable during the migration period. This paper describes development of an interactive remote lecture system providing service integration on voice, image, and data of teaching materials. Access right to the network for dialog among multicast group members is controlled via additional TCP (Transmission Control Protocol) session. A jitter buffer algorithm was implemented to improve the voice communication jitters.
