Due to the advent of presumer and digital production of moving picture, a lot of UCC has been generated by editing the previous moving pictures in various way. It causes a lot of problems on copyright, duplication, and content. In reorganizing the contents, it is necessary to increase productivity and reusability by managing production pipeline systematically through the standardization of moving picture content. For this purpose, we try to develop the moving picture content management system that can manage all kinds of information on the production pipeline, based on SCORM of e-learning by considering production, publication and re-editing. Using the meta-data of content object, user and producer can easily search and reuse the contents. Hence, they can choose the contents object according to their preference and reproduce their own creative UCC by reorganizing and packaging the selected objects. The management of copyright by the unit of scene would solve the problem of copyright. The sequencing technique of SCORM as an interactive storytelling method makes it possible to produce individual contents by user's preference.

This paper is aimed at embodying the optimal system for foreign workforce supply of nation in order to introduce qualified foreign workers at the age of eleven thousand foreigners. It is difficult to employ foreign workers qualified and it makes job rosters' confidence fall down which is the supplementary resources when selecting due to the insufficient job seekers' detailed information. Therefore, the moving control system should be added in current system to deal with these problems. For this, in this paper, we propose that the moving picture embedded system applies to the current EPS utilizing multimedia, network and database technologies as regards adding the function of the moving picture synthesis to recent system. It also suggests the advanced foreign employment control system related to the advanced system which makes employers to hire foreign workers satisfying their requirements and demand.

In this paper, we proposes Moving Picture Compression reducing bit numbers within the block by probability in 3D-DCT considered of temporal axis. From Delta Modification theory for frequency components, bit numbers within the block(4$\times$4) were properly compressed by using the Probability Entropy. At the result for the proposed algorithm, we could find that the values of PSNR for resolution and the compression rate were better than existing methods.

Recently, it is studying to provide to users through internet in the SensorWeb of OGC(Open Geospatial Consortium) saving and maintaining data and image information gathered from sensor network. It is necessary to study about data convergence as binding audio and video for delivering the sensing data and image information to users with real-time system. In this article, it suggests how to convergence sensing data and moving picture collected from the sensor network using index. This program indicates both of them that collected sensing data and information identified of moving picture in the integration index and based on this program provides sensing data moving picture at the same time referencing integration index, if the user asks. To verify suggested method designing real-time multimedia service structure using sensor network and image installation and implementing Ubiquitous realtime multimedia system integrating moving picture and sensing data based on index. As a result of this program, it is confirmed providing real-time multimedia service to request information of application service using integration index collected image and sensing data from wireless sensor network and image installation suggested data convergence method.

With the rapid dissemination of Internet and the fast development of IT technology. utilization and circulation of video files through Internet has been widely popularized. To keep playing a central role in information circulation in this ever-changing environment, libraries should pay attention to the circulation of video content, as it emerges to be an important type information resource. In this context, this paper examines the issues surrounding the development of the video content circulation system, while suggesting foundational knowledge required for the development of the system. First, the author reviews the current state of video content utilization and circulation on the internet and examines the related technical developments. Then, the author explains each component of the video content circulation system, while discussing the issues to be considered in the practical implementation of the system. The paper will provide practical guidelines for the librarians in their investigation and/or implementation of the video content circulation service and system.

본 논문에서는 MPEG2(Moving Picture Expert Group 2)비디오 디코더에서 영상데이타를 디코딩하는 기술에 관한 것으로, 종래의 동여상 처리기에서는 허프만 코드화 처리를 하여 정지영상을 부호화한 후 분할기반 부호화 방식의 동영상 처리기법을 사용하였으나 1프레임의 코드화시에도 많은 계산 알고리즘이 필요하고 이미지의 닮음정도를 객관적수치로 표현할 수 없으므로 비슷한 이미지를 중복 코드화 작업 및 전송 작업을 하는 결함이 있었다. 본 눈문에서는 이를 해결하기 위하여 이미지의 닮음정도를 수치화하고 기준값 이하의 영상은 코드화 작업을 하지않고 계산된 영상 변화값에 의해 구현된 영상으로 대체하여 저장 및 전송하도록 하여 시각적으로 전혀 거부감이 없는 동영상을 구현하였다.

This paper proposes an efficient moving picture compression for video sequences with luminance variations. In the proposed algorithm, the luminance variation parameters are estimated and local motions are compensated. To detect the frame required luminance compensation, we employ the frame classification based on the cross entropy between histograms of two successive frames, which can reduce the computational redundancy. Simulation results show that the proposed method yields a higher peak signal to noise ratio (PSNR) than that of the conventional methods, with a low computational load, when the video scene contains large luminance variations.

The moving picture blur noise of LCD is measured and the characteristics of it are evaluated. From the results, blur noise is generated only when the sight line moves while pursuing the moving image and blur noise is not generated when the sight line is fixed. In addition, decrease of gray level by the image blur has a linearity and velocity dependence. The blur noise simulator based on this experimental results is developed. From the results of blur noise simulation, the faster the moving speed of image is, the more blur noise has increased and these agree with the results of measurement. In the result of simulating blur noise characteristics by the duty ratio control of backlight, noise is reduced by lowering of the duty ratio. but the blur noise increases if there is in the both of adjacent two frames. Moreover, the case of doubling the frame rate to 120[Hz], decreasing the moving speed of the image by making an new image between the adjacent two frames brings the reduction of blur noise.

In this paper, we proposed the method computing the optimal solution of Optical Flow(OF) representing the moving information of moving object and improving the operating speed. In order to do that, we computed the optimal solution of OF using the Combinatorial Hough Transform(CHT) and Voting accumulation and simply searched the moving object compared to conventional method.
