본 연구에서는 다양성영화의 온라인 배급 사례를 분석하였다. 영화의 온라인유통은 일반적으로 극장상영 이후에 매체의 다양화를 통한 수익의 확대 측면에서 이루어지나, 다양성영화의 온라인 유통은 현실적으로 유일한 유통배급망일 경우가 많다. 이 연구는 다양성영화의 온라인 유통양상을 분석하여 다양성영화에 적절한 온라인 배급 형태를 고찰하는 것을 목표로 하였다.

In the paper, designed digital contents security module to check unlawfulness reproduction and distribution of digital contents. This paper applied Diffie-Hellman algorithm that use discrete logarithm and random number as primary for public key application to create encryption key that agree each other through communication channel between DCPS and HOST, and applied Triple DES repeat DES 3 times through 2 different encryption key that is selecting ANSI X9.17 that is key management standard, ISO 8732 and PEM(Privacy-Enhanced Mail) etc. by secondary protection for safe transmission of digital contents in transmission line. Designed security module consist of key exchange module, key derivation module and copy protection processing module. Digital contents security module that design in this thesis checks reproduction and distribution of digital contents by unauthenticated user through user certification function and digital contents encryption function, and protect digital contents transmission line.

This study deals with the technical approach related to the protection of digital video contents copyright, which has currently become a major issue in the digital contents market. With the production and distribution of digital video contents rapidly increasing, various policies and technical approaches are being made in relation to the protection of intellectual property rights. The technical approach from a DRM (Digital Rights Management) perspective was made from various angles, but its limitations have also been exposed in terms of convenience and quality. In this study, rather than the existing encoding certification and watermark technologies, it introduces technical approaches from a content-based copy detection method, while suggesting a copy detection method using the representative color sequence. In particular, this study takes into consideration the distribution environment of the domestic video market and deals with the technical approach in a direction that can control the illegal distribution of high quality videos.

With the advancement of the digital convergence of content and platform, Korean film industry sees good opportunities of maximizing the profits and increased distribution opportunities by independent film makers. Nevertheless, the domestic film market almost entirely relies on the box office sales, which seems to be caused by the stagnation of new additional copyright market. The study aims to address the following problems: First, information asymmetry of the revenues to which the contents providers and the service providers are exposed leads to the distrust among digital film contents businesses and the disadvantages to film makers and investors, in particular. Secondly, the VOD(Video on Demand) market of film industry is adversely affected by the illegal uploads and downloads of film contents, which harms the formation of paid additional market. Based on the examination of current legislation and policy options addressing these issues, the study suggests legislative accomodations and cultural industry policy alternatives to promote the additional market of film industry.

With the development of information and communication technology, the production and distribution of digital contents is rapidly increasing, and the distribution of illegally copied contents also increases, causing various problems. In order to prevent illegal distribution of contents, a DRM (Digital Rights Management)-based approach can be used, but in a situation where the contents are already copied and distributed, a method of searching and detecting the duplicated contents is required. In this paper, a duplication detection method based on the contents of video content is proposed. The proposed method divides the video into scene units using the visual rhythm extracted from the video, and hierarchically applies the playback time and color feature values of each divided scene to quickly and efficiently detect duplicate videos in a large database. Through experiments, it was shown that the proposed method can reliably detect various replication modifications.

In recently, as the interest of media contents increase among internet users, a variety of media contents are circulated in the web. Especially, video-media content in media contents attracts internet user's interest. In conjunction with web 2.0, internet users open and share their making contents by themselves. Their attitude about accepting media contents is not passive but aggressive. Additionally, they create new form of distribution of the flow. Video media content for distribution on the Web is created by experts to a professional content, but Web 2.0 era, the UCC (User Create Contents) in the form of self-produced content is the most. The generated media by the general internet users, but self-produced content, provides video information only and has limitations. To satisfy internet users as consumers in the web 2.0 eras, it has needed to provide actual feeling contents that add various effects not just simple media. Therefore, this paper represents the existing media content with simple information based on the concept of ontology and the meaning to the subject for the media content. We will provide an actual feeling how to offer the configuration of a service model (AF-VS : Actual Feeling Video Service).

This study started from the consciousness that the community media practice studies have been confined to the traditional terrestrial broadcasting. The following research results and implications were obtained by analyzing Daedeok-valley Radio's case to elucidate characteristics of online-based community media and content production and distribution characteristics neglected in previous researches. First, online community media activities are civic/citizen media activities that capture the value of local communities, and this locality is realized through media content production and its online distribution. Second, contents of online community media link members of the community, and individuals become nodes, interacting both online and offline. Therefore, online-based citizen media activities can be utilized effectively as a means to enhance civic participation and to achieve the locality of community in online and offline spaces depending on strategies for online contents production and distribution. Utilizing online infrastructures for media content creation and distribution in Korea demonstrates potential opportunities of local online media to be considered as niche media that can increase its own sustainability.

The organic contents of reservoir sediment can offer a good indicator to events in history of lake life. Reservoir sediment have many information of the past and future fingerprint about development direction of life cycle in biological animals. So, in this study we made an effort to know the distribution of organic contents in Daecheong reservoir sediment. Items for this investigations are such as follows: Loss on ignition, COD, Organic carbon, TN, TP, heavy metal contents, Loss on ignitions were determined in 6.44~15.91% and COD were determined in 1.606~6.859%, organic carbon in 1,077~3.743%. Contents of TP and TN were in the range of 0.083~0.757%, and 0.645~0.926%, respectively.

The Internet provides a new distribution channel of digital contents for conventional media firms such as newspaper, magazine and encyclopedia publishers and broadcasting companies with very low marginal production and distribution cost. In comparison to traditional offline channel, there have been various revenue models in online content markets such as advertising model, subscription model, affiliation fee model, etc. In the earlier of the Internet era, most of online content firms provided their services free in order to boost offline revenue or they depend on advertising revenue sources in lieu of attaining revenue from their contents. However, as many online content firms are confronted with many difficulties in attaining revenues from online advertising model, they began to charge their contents. This paper shows why they charge their contents and explores entry conditions when conventional firms enter online content markets. And also this paper discusses managerial implications related to pricing strategies in online content markets.
