Recently, according to development of wired and wireless networks, contents production of user-defined changes a environment producing contents that it get out of manufactured contents offered by mobile telecommunication company. This paper propose a system proposing and registering a contents service provider of mobile telecommunication company for user-defined mobile contents production and transmission. We propose a system using web hosting service for user-defined mobile contents production and solution for system and transmission for contents production of a person and enterprises.

The previous media has the function that was information of the contents was delivered by only content providers, but the current media makes the interactive function between content providers and general receivers. For this reason, the role of receivers are also expanded in the realm of multimedia and receivers have the roles of the sending and getting information for content user, not more receiver. The constituent members relative to content are content providers, users and user-created content. This paper introduces "the wonderland" the animation process management system for high-level user group. Also, most of images which are made of the animation process are publicly accessible, providing the public or the average user group for making resources easily by using "the wonderland." Although, the general user can get an environment to reedit their own new movie with making the most of provided movie sources are scene and cut units, according to one's taste and one's idea. The materialization of process management system can expand dramatically enough contents, and save the time to edit digital animation or movie, control numerous sources, made an animation processing, and the result output. Such "the wonderland" will significantly help to create future content.

The amount of UCCs (User Created Contents) has been increasing rapidly and is associated with a serious copyright problem. Automatic logo detection in videos is an efficient means of overcoming the copyright problem. However, logos have varying characteristics, which make logo detection and recognition very difficult. Especially, there are frequent logo transitions in a video, comprising several video contents. This disrupts accurate video segmentation based on logos. Therefore, this paper proposes an accurate logo transition detection method for recognizing logos in digital video contents. The proposed method accurately segments a video according to logo and efficiently recognizes various types of logos. The experimental results demonstrate the effectiveness of the proposed method for logo detection and video segmentation according to logo.

We developed a convenience-featured Web browser which is intended to enhance Web users' convenience. The integrated convenience functions are VPV(Visited Page Viewer), APV(Aligned Page Viewer), USC(User Specified Capture), and VAC(Video and Audio Converter) which is the most important feature of FLV(FLash Video file) in UCC (User Created Contents). The four functions are considered ad the most needed functions to the Web users and we referred to the opinion of frequent and advanced Web users. We addressed important algorithms and techniques in terms of the implementation of the above four functions. The implementation methods based on the MDI application using rendering technique same as in Internet Explorer 6.0 are shown with codes. The results of implementation is compared with the survey conducted on 134 Computer Science and Multimedia Engineering major students. All four integrated functions are considered to be useful.

Although the amount of UCC(user created content) rapidly grows nowadays, there are various problems in authoring, distribution and management of this abundant content because the platforms for fabrication and replaying content are not compatible and the authoring environments are not sufficiently interoperable with other site or with each other. In this paper, we propose a CMS(content management system) scheme improved in interoperability to solve these problems, and we design a novel system enhancing the efficiency and speed of content distribution and management by minimizing the repetitions in the processes of production, reshaping, and publication. Moreover the proposed system adopts an improved content management technology by changing from simple point-to-point method to the centralized distribution method, and as for the service scheme, we change from the site link method to the database link method, and we also take duplex interlink scheme instead of simplex one. We finally compare the proposed system to the conventional ones as points of view of compatibility and interoperability to prove the improved performance of our system.

The purpose of this paper is to find an policy vision and action plans for the growth of the Korean cultural contents industry as a new growth power in the 21th century. For this purpose, I referred to sundry records to analyze the characteristics, industrial situation and the prospects of the cultural contents industry. I also made an analysis on the outcome of the cultural contents policy with the help of the official concerned in the Ministry of Culture and Tourism, which made it possible for me to draw a few urgent problems of Korean cultural contents industry. With these preceding analyses, I proposed the strategy and action plans of the government policy for the Korean cultural contents industry as follows : strengthening the creative power of the cultural contents industry, systemizing the healthy circulation of the cultural contents, and improvement of the cultural welfare on the basis of contents.

최근 인터넷의 발달로 디지털 콘텐츠 및 UCC(User Created Contents) 산업이 발전하고 있다. 그러나 이로 인한 부작용도 많이 발생한다. 대표적인 문제는 디지털 콘텐츠의 무단 불법복제나 무료배포행위 이다. 이는 디지털 콘텐츠 산업의 성장과 UCC 제작자의 창작의지 를 저해하여 웹 2.0 시대의 중심인 양질의 콘텐츠 생산을 방해한다. 본 논문에서는 위의 문제를 해결하기 위하여 멀티미디어 콘텐츠의 경매 시스템 과 경매 프로세스를 제시하였다. 본 논문에서는 멀티미디어 콘텐츠에 중고의 개념을 도입하였다. 특히, 모바일 상에서 경매가 가능하도록 새로운 시스템 구조를 제안하고, 멀티미디어 콘텐츠의 경매거래 프로세스를 새롭게 제안하였다. 시스템의 성능 분석 결과 주요 경매프로세스는 성능 분석 과정을 통하여 ${\Theta}$(logN) 의 정수 배(m)의 시간을 사용하는 알고리즘임을 소개하고 사용자나 콘텐츠의 양이 폭발적으로 증가하는 경우에도 시스템의 성능에 크게 영향을 받지 않는다는 것을 보인다.

The purpose of this study is to find the UCC (User Created Contents) communication structure in the perspective of smart-phone technologies or SNS (Social Network Service). In developing the research model, we have focused on selecting the success factors appropriate for the UCC through reviewing past researches and on developing more accurate success measures. The model consists of relation each service (Facebook linked in Flickr and so on), relation of trust, transfer to Social Capital and so on . The result shows thar process of trust based in UCC is the most important determinants of structure and organization network. And collaboration relationship is the most important of SNS used in SSO and Open-API technologies. The practice characteristic of UCC has direct and indirect effect on SNS of improving social trust.

As the number of various types of media data such as UCC (User Created Contents) increases, research is actively being carried out in many different fields so as to provide meaningful media services. Amidst these studies, a semantic web-based media classification approach has been proposed; however, it encounters some limitations in video classification because of its underlying ontology derived from meta-information such as video tag and title. In this paper, we define recognized objects in a video and activity that is composed of video objects in a shot, and introduce a reasoning approach based on description logic. We define sequential rules for a sequence of shots in a video and describe how to classify it. For processing the large amount of increasing media data, we utilize Spark streaming, and a distributed in-memory big data processing framework, and describe how to classify media data in parallel. To evaluate the efficiency of the proposed approach, we conducted an experiment using a large amount of media ontology extracted from Youtube videos.

Recently, UCC (User Created Contents) and VoD (Video on Demand), and multimedia content are growing, IP-TV, Smart TV, OHTV (Open Hybrid TV) various services such as multi platform (Multi-platform) environment, services and QoS issues. To solve this problem, the network efficiently, and improve the quality of content is necessary for the system. In this paper, the network of channels State and transmission of multimedia data based on dynamic resource usage, TCP and UDP, Adaptive dual-streaming system used for design and analysis. In addition, the existing TCP and UDP streaming system using a single protocol for analysis and verification of the effectiveness of the difference between and. This is a disaster, and medical/first aid system will be utilized in the field of feed, are ubiquitous.
