This paper proposes how to develop a multi-sensory virtual reality system based on realistic media that can improve the sense of immersion and reality experienced by the user. We suggest four types of multi-sensory virtual reality system; a realistic media experience system which provides sensory experiences to user by interlocking the media file with the sensory informations and reproducing the sensory information suitable for the scene, a real image-based panorama experience system which maximizes the sense of reality, an experience ball system in which users engage themselves into the system environment to lead the story and immersion of the content through interaction with the system, and a cultural heritage experience system based on hand movement recognition. The suggested systems can be applied in a various area such as education, advertisement, culture and arts, performance, exhibition, sports, game, 4D Experience Center, and so on. We supposed that it can contribute to create a variety of sensible contents services in the realistic media industry through the convergence of media, contents, and devices.

This study tried to analyze the learning effectiveness of multi-media based class by comparing with traditional classroom method. The "Basic Agricultural Technology" course that is one of the required courses of agricultural high school was selected and its contents were digitalized on MS Powerpoint for multi-media based class. The thirty students were sampled for each experimental and control groups. The homogeneity and learning achievement of sample groups were tested for experiment. Same teacher took the classes of two groups and delivered same contents of course. Only difference between two groups was the delivery method, one is traditional classroom teaching method and the other was the multi-media based class. The learning achievements and satisfaction of sample were post-tested in order to analyze the learning effectiveness by comparing two teaching methods. The results showed that there was a significant difference between experimental and control group in learning achievement after ANCOVA controlled pre-test as covariance(F=5.08, p<.05). It means that the learning achievement of multi-media based class was higher than that of traditional classroom group. The results also showed that a significant difference in students’ satisfaction between two groups (t=5.57, p<.001). This study concluded that using multi-media in class could produce more learning achievements and satisfaction of students than traditional classroom method.

Nowadays personal users create a variety of multi-media contents and share them with others through various devices over the Internet since the concept of user created content (UCC) has been widely accepted as a new paradigm in today's multi-media market, which has broken the boundary of contents providers and consumers. This paradigm shift has also introduced a new business model that makes it possible for them to create their own multi-media contents for commercial purpose. This paper proposes a tangible virtual studio using augmented reality to author multi-media contents easily and intuitively for personal broadcasting and personal content generation. It provides a set of tangible interfaces and devices such as visual markers, cameras, movable and rotatable arms carrying cameras, and miniaturized set. They can offer an easy-to-use interface in an immersive environment and an easy switching mechanism between tangible environment and virtual environment. This paper also discusses how to remove inconsistency between real objects and virtual objects during the AR-enabled visualization with a context-adaptable tracking method. The context-adaptable tracking method not only adjusts the locations of invisible markers by interpolating the locations of existing reference markers, but also removes a jumping effect of movable virtual objects when their references are changed from one marker to another.

The English education by Cyber have attracted the interest of people due to the change and development of education situation. To enhance the effect of education in foreign language, it is indispensable to work the production of lecture textbook which makes use of multi-media technique. The purpose of this paper is to search the effect of multi-media textbook and to show how well it could be practically used through the production of multi-media textbook.

The purpose of this study is to investigate the characteristics of diverse contents service of EBS providing on the multi-platform in the era of smart media. This study investigated contents service of EBS in order to seek and suggest EBS's competitiveness in the era of smart media environment. As a result, EBS is providing real-time service, VOD and e-learning, but its current contents service is concentrated on providing e-learning service. This study recommended that EBS need to reinforce contents suitable for various multi-platform uses. It also suggested EBS need to cooperate with diverse webs service and SNS service in order to widen openness of its platform, and to provide not only diverse contents, but also applications by offering mobile and on-demand contents and services. Finally, this study proposed that EBS is needed to move towards a more public and comprehensive media portal.

Digital information society shows a variety of contents of cross-categorial digital media in their inner or outer forms and concepts of the artistic aspects. In order to cope with such a complicated, unexpected trend in digital media and its industry, a new approach in the design process needs to be developed and adjusted with the new equipment of the creativity-thinking process of 'the Multi-Sensory Device (MSD),' 'the Multi-Dimensional Device (MDD),' and 'the Storytelling Device (SD)' in the Prism Effect-based Creativity-Thinking Process (PECTP). The PECTP is in principle designed to practically work with the four distinct techniques: 1) Physical Activity, 2) Linguistic Activity, 3) Visual Activity, and 4) Complex Activity. Consequently, this thesis notes that the nature of the cross-categorial design contents is necessarily non-directional since the creativity power inside the Prism Effect results in openness and diversity.

For a P2P network, the contents distribution is a very important service because the contents provider is not fixed. And in the P2P media streaming, a request peer replays and saves media data simultaneously, and after streaming it acts as a new source peer providing media files to other peers. Therefore streaming and file saying operations should be simultaneously carried out in order to distribute contents through the P2P network. In this paper, a P2P multi-source media streaming system which can replay the contents data during downloading is proposed and implemented. The system reduces the user response time and the number of simultaneous user increases more than two times. Moreover, transmitting a part of media file makes fast distribution and diffusion of contents possible.

The Terrestrial Digital Multimedia Broadcasting (T-DMB) system supplies high quality audio comparable with VCD in 7 inch display and high quality audio comparable CD at the mobile reception environment T-DMB will launch commercial service at the middle of 2005. However the bandwidth for audio data and the number of channels are restricted to 128 kbps and 2 respectively in the current T-DMB standard because of the limitation of available bandwidth for multimedia data. This Paper Proposes a novel media processor structure for providing multi-channel audio contents oyer T-DMB system allowing backward compatibility with the legacy T-DMB receiver. Furthermore. we also Propose an adaptive receiver structure to supply optimal audio contents on various speaker configuration in T-DMB receiver. To provide multi-channel audio contents allowing backward comaptilbity with the legacy T-DMB receiver, the additional data for multi-channel audio are defined as a dependent stream of main audio stream. The OD strucure for control an additional multi-channel audio elementary stream is proposed without changing the BIFS of the legacy T-DMB system.
