웹 콘텐츠의 특성상 분배, 복제 및 조작이 용이하기 때문에 원 정보의 저작권 침해로 인한 재산권 침해 피해가 나날이 증가하고 있어, 막대한 비용이 투자된 웹 콘텐츠의 무단도용을 방지하고 분쟁 발생시 소유권에 대한 분쟁을 해결하기 위한 노력이 계속되고 있다. 본 논문에서는 웹 콘텐츠의 소유권 및 저작권 보호를 위한 오디오 콘텐츠에 대한 워터마크 생성, 삽입 및 검출, 검증 시스템을 설계 및 구현한다. 본 시스템은 저작권 보호에 대한 전문지식이 없는 일반관리자도 용이하게 이용할 수 있는 사용자 인터페이스를 갖추고 있으며, 이러한 디지털 오디오 워터마킹의 적용을 통한 소유권 및 저작권 보호는 궁극적으로 콘텐츠 제작 의뢰자로 하여금 제작 의지를 강화하여 제작 의뢰 건수를 증가시킬 수 있을 것으로 기대되어 문화콘텐츠 등의 디지털 콘텐츠 제작업체의 매출 신장에 도움을 주게될 것이다.

In this paper, the write analysis the application of basic video content of Mobil Device Platform in China and studies the future development scheme. According to the survey, as of 2019, 78% of Chinese total population is the Internet service users and application software users. Mobile Device Platform is independently developed to provide video content application services, which already have 640 million video application users from 2013 to the present. 65% of users install and use more than two video content applications. In China TikTok, Kuai Shou, MeiPai and other video content applications, not only can easily achieve simple user interface and users can directly shoot video content. These production functions is different from YouTube, a famous video platform in the United States. In the video platform market, the core competitiveness is content creation. In the future, the integration of video content of VR, AR and other video projects will expecte to further activate the video platform market.

In this paper, we developed a multi-view video content based on real-world technology and a pilot using the production technology, and provided realistic contents production technology that can select a desired direction at a user 's view point by providing users with various viewpoint images. We also created multi-view video contents that can indirectly experience local cultural tourism resources and produced cyber tour contents based on multi-view video (realistic technology). This technology development can be used to create 3D interactive real-world contents that are used in all public education fields such as libraries, kindergartens, elementary schools, middle schools, elderly universities, housewives classrooms, lifelong education centers, The domestic VR market is still in it's infancy, and it's expected to develop in combination with the 3D market related to games and shopping malls. As the domestic educational trend and the demand for social public education system are growing, it is expected to increase gradually.

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 CPMS(content publication and 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.

For the activation and wide distribution of User Created Contents (UCC) sites have diversified user-created possibilities. Among these contents, User Created Game (UCG) sites are places where users can create and share their game contents with others. The method of UCG development can be classified into two categories according to the uses' level of professionalism. First, the method of using the authoring tools is suggested for those unfamiliar with the development or creation of contents. Although the authoring tool is easy to use, there are many functional limitations. Second, development using program languages is suggested for trained advanced users but has the limitation of a prolonged development period. This paper proposes a new method, generating the script which will expand the current functional limitations entailed behind the authoring tools used by first time and less trained users. In order to verify the proposed method in a real UCG development environment, a framework encompassing GUI, script generating function and program source generating function were constructed.

최근 VR은 다양한 장르에 콘텐츠를 융합함으로써 사용자에게 공간의 제약 없이 현장감 제공이 가능해짐에 따라 관심을 받기 시작했다. 또한 실감 콘텐츠 기술 확보가 가능해짐에 따라 다양한 사용자 체험형 콘텐츠 개발도 가능해지고 있다. 하지만 국내에서 VR산업은 게임분야를 제외하고 활용정도가 낮다. 이에 본 논문에서는 실감형 가상 여행 콘텐츠를 제작하여 HMD에 디스플레이하는 방법을 제안 및 구현한다. 360도 영상과 VR로 표출했기 때문에 개인방송 여행 콘텐츠에서 사용자에게 현지에서 직접 경험하는 듯한 몰입감과 현장감을 제공하고, 사용자 인터페이스를 접목하여 양방향 통신이 가능하도록 설계하여 콘텐츠를 체험하는데 편리성을 극대화하였다.

최근 디지털 홀로그래피는 3차원 영상을 획득, 처리 및 재생을 하지만, 디스플레이 전자 소자 특성에 의한 시야각이 작아서 사용자의 관찰 가능한 시역이 제한적인 단점이 있으며, 따라서 복원된 입체 영상과 사용자 사이에 상호작용 서비스 제공이 용이하지 않는 한계를 지니고 있다. 본 논문에서 우리는 $360^{\circ}$ 전방향 (1,024 시점)의 홀로그래픽 3D 콘텐츠를 FFT 알고리즘을 이용하여 생성하고, 이 콘텐츠를 디스플레이할 수 있으면서 동시에 이 콘텐츠와 사용자 간 상호작용이 가능한, 광시야각 (${\pm}60^{\circ}$) 홀로그래픽 디스플레이 시스템의 설계 및 제작한 결과를 실증한다.

This study organizes an immersive content production pipeline using Meta Quest Pro as an asymmetric virtual environment where mixed reality(MR) and virtual reality(VR) users participate and interact together. Based on this, we compare and analyze the differences in presence and experience provided by the user's experience environment. The proposed production process is to build an integrated development environment using Meta XR All-in-One SDK based on the Unity 3D engine. This includes a real space analysis method using the Room Model function for organic and accurate interaction between MR users in the real world and VR users based on virtual scenes at fixed coordinates. Based on this, this study produces immersive table tennis content where MR and VR users participate together. Finally, we conduct survey experiments to compare and analyze the effects of differences in platform and participation methods on presence and experience using the produced content. As a result, this study confirmed that all users can feel a satisfactory presence and experience within an experience environment where real and virtual correspond.
