The real-time video education is used as an effective method of operating classes that replaces face-to-face education of instructors and learners in remote areas. However, the existing video call and video conferences system is mainly used, and this is effective in linguistic education because it focuses on lecture through video, but it is not utilized in other education. In this paper, we propose a design model of real-time video system that can improve the effectiveness of science curriculum and mathematics education by providing the functions that can be utilized during class by improving limitations of image - oriented image education.

In this paper, we carry out a cyber group consultation by means of the video-based education system, and verify the effects. For the verification of this study, two assumptions were set up. These assumptions were inspected by selecting 45 students of D elementary school located in a big city, and coming up with a test utilizing one of video-based education systems. Following up, a self-respect test form and a questionnaire were made to verify of the group consultation to the video-based education system, and by analyzing the test form and the questionnaire, the conclusion of this study was finally drawn. The conclusion gained through the process adove is as follows: It turned out that real-time video-based cyber group consultation promoted self-respect and enthusiastic participation of consulters as well as formed emotinal stability and a close affinity between the consultant and the consulter through active interaction. The results of this video-based education system operation will be helpful to broaden the area of elementary school cyber group consultation. Further, it is thought that it will contribute to the basic investigation to verify the educational effects of Multi-point imaging system in the run-up to the operation of full-scale real-time video-based education systems.

최근 회선망의 확충과 멀티미디어기술의 발달로 대용량의 데이터를 보내고 받을 수 있게 되었다. 이에 인터넷 방송이나 원격 화상교육등 질적으로 높은 서비스를 받을 수 있게 되었다. 그러나 멀티캐스트를 중심으로 개발되었을 경우 대부분의 라우터에서 지원하지 못하는 단점이 있으며 멀티캐스트를 지원하는 라우터로 교환할 경우 추가적인 비용부담이 있게 된다. 본 논문에서는 이러한 단점을 극복하기 위해 원격화상교육을 위한 유니캐스트와 P2P를 응용한 에이전트를 설계 및 구현하였다.

화상회의시스템이란 영상 및 멀티미디어를 활용하여 원격 회의를 가능하게 하는 정보전달 매체로 가격이 저렴해지면서 학교 현장에 보급되기 시작하였다. 이 시스템의 활용 범위가 확장되어 교육청과 학교간의 회의뿐만 아니라 실시간 원격연수에도 활용이 가능하게 되었다. 그러나 현장의 교사들은 화상회의 시스템에 대한 지식과 응용 프로그램의 사용 경험 부족으로 적극적인 활용에 어려움을 겪고 있다. 본 연구에서는 현재 학교에 널리 보급되어 있는 MCU방식과 최근 새롭게 개발된 IP 멀티캐스팅 방식의 원격교육 시스템에 대한 장단점을 비교하고 분석하여 교육 현장에 적합한 화상회의시스템에 대한 평가를 할 것이다. 그리고, 실시간 원격교육 프로그램을 위한 화면의 설계 결과와 화상회의 시스템과의 인터페이스 방법에 대한 설계 결과를 제시할 것이다.

최근 초고속 인터넷망의 발전으로 실시간으로 화상 교육 시스템 구축이 가능하게 되었다. 그러나 기존의 화상교육 시스템은 단순히 사용자의 얼굴과 음성만을 전달하기 때문에 교육적인 측면에서 실감나는 교육 시스템으로는 볼 수 없다. 본 연구에서는 웹캠으로 촬영된 영상을 3D 가상공간에 적용시켜 사용자가 교육 현장에서 교육활동이 이루어지는 것과 같은 실감나는 교육 서비스를 제공할 뿐만 아니라 교육에 필요한 문서, 음성, 자료 공유를 실시간으로 할 수 있는 시스템을 개발하였다.

This study analyzed learners' satisfaction and in-depth interviews with teachers after operating a software practical curriculum as a real-time video class for fifth and sixth graders in elementary school. The correlation between learner's presence, class overall, interaction, and real-time video class satisfaction showed that the positive correlation between presence, class overall, interaction, and satisfaction with real-time video classes was somewhat high. There were some differences in the real-time video class participation environment and real-time video class satisfaction, but it was not found to be statistically significant. In the case of teachers, it was difficult to respond to problems occurring in each student's individual environment, interactions between students, and individual feedback problems for a sluggish student. To solve this problem, opinions such as preliminary guidance and verification of real-time video class connection environment, error support for sluggish students and individual class participation environment, and feedback on individual tasks using LMS were suggested.

The proposed QoS Agent System for distance video learning is used unicast and P2P. This method is developed for decreased the traffic of server by control agent. First step capture from stream server's camera, and transmitted streaming data to the first CSplayer(c/s), and outrank CSplayer transmitted streaming data to the subordinate CSplayer controled by QoS Control Agent.

Most homepages of schools are available to publicize activities of education, to load educational materials efficiently. But we can't use current homepages of schools in making characteristic information or sharing educational resources. In this study, this I-CUBE system with RSS was designed and embodied for sharing characteristic educational activities and works in schools. Currently, I-CUBE is being under experimental test for sharing education activities and making community in elementry schools,.

In the multimedia streaming technology, the unicast method require additional cost by an increase traffic according to increase a number of users. The multicast method can solve this problem, but it don't have connection and control information of clients. Now, the most routers support only unicast. Also it has a problem with an exchange of service in other ISP. This paper proposes traffic agent system which is applied unicast and P2P(Peer to Peer) for distance video teaming to overcome this problem. The proposed system decrease the traffic of stream server by control agent, and cut down expenses of network. This system is tested under the distance video leaning using JMF and application software.
