  • To transmit multimedia information efficiently and use it in realtime, it needs a private multimedia terminal for service type. But multimedia information terminal was developped for of offered service type in case by case. Accordingly, general multimedia terminal have not been developed yet. Multimedia database structure and standard communication protocol must be designed first to develop the general multimedia terminal. Multimedia database structure needs to store the various multimedia information consistently and, standard communication protocol access the database transparently. In this paper, we design a multimedia database structure and communication protocol that are able to access the multimedia information on distributed database servers in the network.

  • This study was practiced in order to develop a textbook to improve early childhood teachers' ability to use multimedia required by kindergartens and to examine its effects. First, investigation of the status of multimedia application of early childhood teachers in kindergartens was done along with looking through their attitude and anxiety. The expertise and the multimedia education was required in early childhood education and curriculum. As a result, 15 categories and 50 subcategories under 4 themes were drawn through the procedures of qualitative analysis. The conclusions obtained through this study were the following: First, the education for multimedia application related to the tasks required in kindergartens is needed instead of the common education for multimedia application, to improve the ability to use multimedia for early childhood teachers. Second, multimedia education based on visual theory for the purpose of early childhood education, rather than common features-centered multimedia education, is helpful for the improvement of early childhood teachers' ability to use multimedia. Finally, the improvement of early childhood teachers' ability to use multimedia will be a chance to provide children with a better educational environment.

  • The purpose of this study was to develop the computer assisted instruction program in multimedia environment, to examine the relative effects of two types of multimedia learning on science achievement and attitude towards science learning and to investigate the effects of treatment and students' learning ability. The results of this study were summarized as follows: 1. On science achievement; The multimedia learnings were more effective than the traditional one. Difference between multimedia learning I (through individualistic learning) and multimedia learning II(through peer interaction) was not significant. There was not interaction effect of treatment and students' learning ability. 2. On attitude towards science learning; The multimedia learnings were more effective than the traditional one. The multimedia learning I (through individualistic learning) was more effective than the multimedia learning II (through peer interaction). There was no interaction of treatment and students' learning ability. 3. On students' perceptions on multimedia learning; The students in the multimedia classes showed the multimedia learning were good in causing interest. making students absorbed in studies, and giving many learning materials, but not good in a couple of points such as making students bored and not explaining in detail.

  • Currently for the development of internet and network technology, since request of service for the large volume multimedia data has been more increased, multimedia users want the convenience and accuracy of multimedia service system about storing and retrieving of the multimedia contents. To satisfy the request of users, metadata management for the diverse information of multimedia contents is very important. However, the metadata management for the multimedia contents is difficult because the metadata standards are different each other for the type of multimedia data and service. In this paper, we propose the integration metadata management system structure which extends previous metadata management system based on text for the multimedia contents metadata which are expressed differently each other according to the multimedia data or service type.

  • With recent progress of related multimedia computing technologies, it is necessay to retrieve diverse types of multimedia data based on multi-media content and their relationships. However, different from alphanumeric data, it is difficult to provide relevant multimedia information, be-cause multimedia contents and their relationships are implied in multimedia data. Therefore, in case of a multimedia news service system that is a representative multimedia application, most of new services provide relevant news about text articles and retrieval of multimedia news such as video news or image news are provided independently. In this paper, we present an XML-based multimedia news management system, which provides integrating, retrieval, and delivery of relevant multimedia news. Our data model composed of media object, relationship object, and view object represents diverse types of multimedia news content and semantically related multimedia news. In addition, a proposed view mechanism makes it possible to customize multimedia news, and therefore provides multimedia news efficiently.

  • Developing tailor made Multimedia courseware ensuring effective implementation of instruction strategies is a challenge that manifests in myriad problems of software design and coding. In this paper an attempt has been made to analyse and identify coding and implementation problems, in the backdrop of using two different multimedia software development tools i.e. Visual Basic and Toolbook, which underpin the development and effectiveness of use of multimedia courseware. Solutions to such problems have been discussed in context of Tool book. The examples presented in this paper are based on the experience of designing and implementation of two large scale professional quality Multimedia courseware development projects.

  • We address an integrated multimedia framework based on a software agent platform for context-aware multimedia computing. We adopt the FIPA (Foundation for Intelligent Physical Agents) platform which provides agent communications and management mechanisms. In order to express context information, we use MPEG-21 metadata for describing user characteristics and usage environment. We encapsulate such context information as a FIPA message to be delivered between agents. Based on context information, appropriate multimedia content delivery becomes possible. We present our system implementation with a use case scenario and show that our proposed framework is effective for context-aware multimedia computing so that personalization of multimedia consumption can be possible.

  • Multimedia services in the cloud have become a popular trend in the big data environment. However, how to efficiently schedule a large number of multimedia services in the cloud is still an open and challengeable problem. Current cloud-based scheduling algorithms exist the following problems: 1) the content of the multimedia is ignored, and 2) the cloud platform is a known parameter, which makes current solutions are difficult to utilize practically. To resolve the above issues completely, in this work, we propose a novel distributed multimedia scheduling to satisfy the objectives: 1) Develop a general cloud-based multimedia scheduling model which is able to apply to different multimedia applications and service platforms; 2) Design a distributed scheduling algorithm in which each user makes a decision based on its local information without knowing the others' information; 3) The computational complexity of the proposed scheduling algorithm is low and it is asymptotically optimal in any case. Numerous simulations have demonstrated that the proposed scheduling can work well in all the cloud service environments.
