According to the increase of audio and video data utilization, the presentation of multimedia data contents and the work of retrieving, storing and manipulating a multimedia data have been the focus of recent work. The display for multimedia data should retrieve and access the contents easily that users want to present. This study is about the design and implementation of a system to retrieve multimedia data based on the contents of documentation or the caption information of a multimedia data for retrieving documentation including multimedia data. It intends to develop an filtering step to retrieve all of keyword within the caption information of multimedia data and text of a documentation. Also, the system is designed to retrieve a large amount of data quickly using an inverted file structure available for B+ tree.

With the development of multimedia and network technology, the production of multimedia contents is rapidly increasing. Meanwhile, the technology to search and use the contents is still insufficient. There are standards for multimedia contents to address the problem, but they cannot fully support diverse multimedia data types or ensure their interoperability. In this paper, an ontology-based content search system is proposed to ensure the interoperability of multimedia contents. The ontology is configured by presenting the rules for it using the schema structure of the multimedia description scheme (MDS) of MPEG-7. Based on this ontology, the association of the multimedia data is expanded to design an access system that allows semantic search.

In order to enhance instructional effects of multimedia contents, it is critical to emphasize the importance of interface and the affective aspects of learner characteristics in design processes. The main aim of this research was to assess the needs for evaluating icon design strategies on the basis of children's sensibilities by investigating differences between children and teachers in their sensibilities to the icons used in multimedia contents for elementary education. Some interesting findings were obtained from the research. Children had richer sensibilities to the icons presented in multimedia contents than teachers in terms of the average number of adjectives reflecting sensibilities. Among the children group, children living in urban areas showed richer sensibilities to the contents than those in rural areas. When the frequencies of the use of 5 adjectives commonly used by the two groups were compared, teachers showed positive sensibilities, but children demonstrated some negative sensibilities. Also children demonstrated richer sensibilities to certain contents than teachers. The results of the research indicated the need for evaluating icon design strategies on the basis of children's sensibilities in designing multimedia contents for children.

This study was designed to develop e-Learning multimedia contents to provide the first aid rescuer with the basic resuscitation, members of the public, corporations and any other institutions who wish to learn this skills. It is carried out from October to December in 2001. This program was constructed on the basic of the network-instructional system Design model, this model has severalprogressive steps, which includes the planning, analysis of the contents, development of the contents, instructional design, development of web-based and multimedia, pilot test, implement, and evaluation. The URL of this site is http://www.cyber.hc.ac.kr named as the cyber education program for the basic resuscitatingskill. This contents consisted of 8 chapters providing as follows : Introduction, anatomy and physiology of heart-ling, Adult Cardio-Pulmonary Resuscitation, Adult Foregin-body Air-Obstruction, Child Cardio-Pulmonary Resuscitation, Child Foregin-body Air-Obstruction, Infant Cardio-Pulmonary Resuscitation, Infant Foregin-body Air-Obstruction. To make the learning more interesting, as much animation and videos were integrated. In conclusion, this e-Learning multimedia contents will be useful for student as well as members of the public. It significantly increases the chances of saving the life of person who has collapsed.

Recently, as the era of ubiquitous has arrived, an infrastructure for the short-distance wireless communication has been extended socially, and thus a variety of services are being proposed. The Multimedia Contents Delivery System using the ZigBee, in particular, has an important stance in enlargement of a variety of services in the aspect of individual-oriented service support though Wireless Personal Area Network (WPAN). Nonetheless, the ZigBee, or the IEEE 802.15.4 Standard, has many restrictions on the Multimedia Contents Delivery System due to the low data transport rate. In order to improve the ZigBee which presents a limit on the transport rate at the IEEE 802.15.4 Standard, this thesis has designed the burst mode which is a method of transmitting a certain amount of data in block units at a high speed without any stoppage until the completion of the transmission. Also, to provide a Multimedia Contents Delivery Service with an application of the normal data transmission mode, it improved the transmission performance of the ZigBee. In addition, for the Multimedia Contents Delivery Service under the ubiquitous environment, it designed and implemented a broadcasting Multimedia Contents Delivery System based on the ZigBee to conduct a comparative analysis on the data transmission performance according to the transmission method.

In order to serve effective teaching and teaming environments with an appropriate harmony of hard technologies and soft technologies and to contribute to multimedia contents design and development this study shows that the theoretical backgrounds, producing backgrounds, contents scenario, and related research as well as their use and integration into realistic classroom. In our environments, it is believed that it is possible for us to develop effective mathematics educational multimedia development fitting to our culture and emotion. Thus it is urged that the government should support the professional multimedia development ＆ production association enthusiastically.

Recently, many kinds of TV contents based on multimedia need transmission systems without the saved. In this study, we develop the streaming device and smart app to transmit and play without store for multimedia contents such a broadcasting, internet, VOD, video, and animation. To do this, we compare and analysis main CPU products, broadcasting tuners and interfaces for streaming sources, and memory products. We then design and implement the streaming device which supports 30fps@FHD H.264 decoding and streaming, and multimedia sources with more than three. We develop the software for these requirements. Thissystemis useful to support billing service for multimedia contents.

In recent Information Environment, various Multimedia contents are getting noticed. But, since these contents have various formats of representation and very wide range of information, it was difficult to retrieve contents that user wanted and to utilize it. To solve these problems, many studies presented draft standards for adding metadata to contents, and then, semantic search for contents had become available. Unfortunately, as the number of metadata standards and contents increased, the lack of interoperability between contents was begun and users are faced with difficulty of search contents again. To improve these problems, this paper supports interoperability between metadata standards and expands the semantic relationship between elements and proposes an ontology which is named TOFIC(The Ontology For Imagery Contents) for enhanced semantic search. In TOFIC, the semantic relationships between MPEG-7 and TV-Anytime are classified, and extended new semantics are defined. As a result, semantic search for multimedia contents is enhanced and it is possible to retrieve most of the multimedia contents that exist on the current information environment consistently. In addition, it supports enhanced content-based search for multimedia contents.
