This paper describes issues and consideration on authoring of interactive multi-view visual content based on MPEG-4. The issues include types of multi-view visual content; scene composition for rendering; functionalities for user-interaction; and multi-view visual content file format. The MPEG-4 standard, which aims to provide an object based audiovisual coding tool, has been developed to address the emerging needs from communications, interactive broadcasting as well as from mixed service models resulting from technological convergence. Due to the feature of object based coding, the use of MPEG-4 can resolve the format diversity problem of multi-view visual contents while providing high interactivity to users. Throughout this paper, we will present which issues need to be determined and how they can be realized by means of MPEG-4 Systems.

최근 정보의 형태는 텍스트나 이미지 기반에서 벗어나 복합 멀티미디어, 즉 동영상 위주로 빠르게 이동하고 있다. 특히 사용자에 의해 제작되고 유통되는 동영상 UCC의 급격한 부상은 사용자의 정보 생산력과 정보 공유, 소비 형태를 능동적으로 변화시키고 있다. PC 뿐 아니라 IPTV에서도 주요 서비스 모델로 관심을 받는 동영상 UCC는 향후 지식 결부형 학습 콘텐츠로 옮아갈 것이라 예상되고 있으며 여기에는 수익 모델의 개발과 저작권 보호 이슈가 해결해야 할 선결 과제로 인식된다. 이에 본 논문은 방송 콘텐츠 제공 표준 기술인 TV-Anytime, 학습객체메타데이터인 LOM(Learning Object Metadata)을 기반으로 OSMU 동영상 UCC 학습 콘텐츠 서비스 모델을 위한 에디터를 설계하고 외부 콘텐츠 소스를 활용할 수 있는 콘텐츠 저작 시나리오에 기반한 메타데이터를 설계하였다. 이를 통해 사용자의 다양한 지식을 활용할 수 있는 UCC 학습 콘텐츠 서비스 모델 발굴과 콘텐츠의 확대 재생산에 있어서 적극적인 저작권 보호가 이루어질 것을 기대한다.

현대에 집필되는 소설이나 시나리오 등의 스토리는 점점 플롯이 복합해지고 캐릭터가 입체적으로 변해가고 있다. 여러 개의 이야기가 동시다발로 진행되고, 다양한 캐릭터들이 복잡한 관계로 얽히면서 갈등 구조를 형성하기 때문에 작가는 창작 과정에서 작품 속 캐릭터들에 대한 정보를 정확하게 인지하고 관리해야 하는 부담이 점점 커지고 있다. 창작 과정에서 생산되는 수많은 정보들에 대한 작가의 인지적 부담은 정보에 대한 작가의 잘못된 기억과 혼란을 초래할 수 있으며, 이는 결국 작품의 완전성과 무결성을 저해하는 요인이 된다. 따라서 본 논문에서는 작가가 작성한 원고를 분석해 캐릭터의 대화 이력을 추적하고, 캐릭터가 아는 정보와 모르는 정보가 무엇인지 추적하여 작품의 모순을 막고 작가의 창작 활동을 도와주는 작품 분석 시스템을 소개한다.

Nowadays, many graphic researchers are interested in 3D outdoor environment. They want to express more realistic natural background with natural phenomenon because computer hardware has become more powerful and increased a demand for a background of 3D natural environment in a content. Especially, e-sports contents and simulation contents with outdoor environment need more natural environment for a background than indoor contents. It is very important technology for a quality of 3D outdoor contents. We propose a software EMtool(Environment Making Tool) for authoring of natural environment for realistic contents. EMtool has been developed to depict relationship and interaction between natural phenomena and include methods for creating natural environment and natural objects. The proposed results are applied to real-time 3D contents such as 3D golf games and simulations for natural objects.

Interest in companion screen services and high-definition television broadcasting services are rising along with the advanced of digital broadcasting communication technology. Not only providing good-quality broadcasting services in the main screen, but also creating added values of companion services in the secondary screen are important. In this paper we suggest a platform and a related authoring tool generating adaptive companion screen services according to user contexts. The Platform providing adaptive companion screen services based on user environment is designed and implemented for real service market. Proposed platform organizes a higher quality content service considering both user contexts and demands of service providers in real time, and the related authoring tool enables a novice user interface designer and service director to make adaptive user interfaces quickly and easily. We developed and simulated this platform in accordance with Korean UHD IBB standard which provides interactive service applications.

The digital cartoons market is looking for a new growth momentum as the radical increases of the demands and markets about the mobile contents with portable instrument popularization. The conventional digital cartoons markets which are based on web-toon, page viewer cartoons and e-paper cartoons have been studied various fields to overcome some limitations such as the traditional cartoons had. The mobile cartoons which have been changed more and more, have some canvas limitations due to the mobile screen size. These limitations lead to the communication problems between the cartoonists and the subscribers and resulting some obstacles of mobile cartoons activations. In this paper, we developed a authoring tool applied the Screen Flow method to overcome inefficiency of conventional authoring methods. This proposed method can reflect the cartoonists' during the process of authoring mobile cartoons, thereafter we studied about the authoring method of mobile cartoons and its effects. For the convenience of users creating and distributing content in a way has been studied.

This paper suggests methods to chronicle and track the history of dialogues exchanged among characters to prevent logical errors of a story. As for stories that are long with many characters, especially in full-length novels and co-written stories, cognitive burden is imposed on a writer. If the writer has confused understanding of a character, then a logical error would enter the story. This would compromise completeness and integrity of writing. Against the backdrop, this paper shows how dialogues among characters are chronicled and tracked by using the aforementioned tracking methods through design of a writer support system that relieves a writer's cognitive burden while supporting the writing and through an analysis of existing novels. In addition, we showed the accuracy results of average 68.5% through the performance evaluation of the query used in the dialogue history tracking.

As augmented reality (AR) technology has been utilized to enhance the user experience, several AR applications have been developed in the cultural heritage domain. Although there has been significant progress in this area, naive augmentation representation becomes an obstacle to provide an enhanced user experience and there has been little research on an effective AR experience methodology that reflects the characteristics of AR technology. Furthermore, the development of temporary content that comes from the absence of the authoring framework restrains the content ecosystem, which is an essential requisite for sustainable service. To resolve these issues, we propose a space-driven AR experience methodology, Spacetelling, to extend established object-oriented augmentation trends and Storyscape that generates spatio-temporal related contents for the spacetelling and supports sustainable service. Moreover, we present the wrap-up system framework covering both features mentioned above for the archeological site tour. Finally, we present our work-in-progress project, K-Culture Time Machine Project, to investigate the practical feasibility of our proposals. Through these proposals, we expect that sustainable AR applications with improved user experience will be possible in the cultural heritage domain.

자막은 청각장애인들의 의사 소통, 정보 전달 및 정보 획득에 중요한 부분을 차지하는 서비스이다. 특히, 지상파 DTV 에서 청각장애인의 방송시청권보장을 위한 일환으로 제공되고 있는 폐쇄자막은 지상파 DTV 뿐만 아니라, 케이블, 위성방송, IPTV 및 VOD 서비스에서도 활용이 가능한 재활용성이 높은 콘텐츠이다. 그러나, 속기사에 의한 실시간 폐쇄자막 서비스가 제공되는 방송환경에서 많은 방송 프로그램의 폐쇄자막들이 일회성으로 사용되고 사라지는 경우가 많다. 본 논문에서는 이러한 폐쇄자막 콘텐츠의 미디어 매체별 재활용성을 높이기 위한 한 방법으로 CEA-708 표준을 지원하는 폐쇄자막의 사전 제작 및 기저작된 자막의 편집을 위한 저작도구를 소개한다.

Recently, discussions on Metaverse, which represents the transcendent world, have been dominant for some time. Cases related to the Metaverse are introduced through various media and are continuously attracting attention as the next generation of the Internet. This study reviews the business model and the ecosystem overview, focusing on service cases related to the Metaverse. The widely used business models include content production and sales, media brokerage fee, and marketing fee. The Metaverse ecosystem is formed around games, with major players in game production, authoring tool & support SW, intelligent cloud service, and game platform expected to lead the market. Results show that a strategy to secure the leadership of the Metaverse, such as the business model expansion conditions, a strategy to foster a game-oriented Metaverse ecosystem, and technology development for the realization of the ultra-realistic Metaverse, is necessary.
