본 논문에서는 비디오 콘텐츠 제작에서 비디오 영상의 합성 효과에 대해서 제안한다. 비디오는 동화상으로 정지 영상에 움직임을 주어 동화상으로 나타낸다. 즉 프레임의 움직임으로 영화는 24 프레임을 TV는 30프레임으로 영상을 전송한다. 영상은 비디오카메라나 여러 광학 렌즈를 통하여 촬영하여 영상을 얻게 되는데 자연 현상을 촬영하여 영상을 얻거나 목적과 필요에 따라 다양한 편집 방법과 효과로 영상을 얻게 된다. 촬영한 영상은 자연 그대로의 메시지를 가지고 있지만 영상의 효과를 주기 위해서 다양한 비디오 효과나 합성을 통하여 새로운 영상을 얻게 된다. 따라서 이러한 영상은 시각 효과가 크고, 메시지 전달의 효과를 갖는다. 본 연구에서는 비디오 영상을 보다 효과적으로 나타내기 위해서 합성을 적용하며, 정지 영상 기법과 동영상 기법의 적용하여 효과에 대한 비교를 나타낸다.

Problem of compatibility, contents protection, contents circulation etc. was caused between contents offerer and consumers by indiscreet rights technical development about digital contents. Therefore, MPEG-21 framework proposed the REL(Right Expression Language) based on XML(extensible Markup Language) by rights expression language for rights management. We designed and implemented of the REL document editing system that rights creation and edit are available efficiently about contents easily without comprehension of MPEG-21 framework and client system that present consumption method of REL document.

Light Drawing is a photographic technique which exposures are made at night or in a darkened room usually by moving a hand-held light source[1]. Due to the limitations of equipment and environment, users having difficulty in drawing a picture in 3D space. If user take a light drawing, they need a camera that have function and darkened environment. Alternative solution is that we can make a light drawing picture by using the computer drawing tool as in Photoshop. Nevertheless, this solution will let the User lose their interest in drawing because this solution cannot synchronize between the real action of human hand motion and the electronic input devices such as mouse and keyboard. This paper proposed a digital content that can make light drawing easier. We used a digital content that will facility Light Drawing easier. We can measure the light spot position by using the stereo camera. Based on the measured position of the light spot, we reproduce light drawing in virtual space by using drawing effect method.

UCC stands right in the center of web 2.0 era represented by share, participation, and openness. Moving picture UCC has been facilitated by If infrastructure advancement and sociocultural changes. Its prospect is expected to be brighter because presumers are spreading, cost of creating and distributing contents is greatly reduced, and there is going to appear more companies utilizing UCC in improving firm's competitiveness. In this paper, various UCC business models are analyzed and hot major issues faced by UCC industry such as profit model and copyright are discussed. In addition, strategies for UCC business success and opportunities and challenges confronted by UCC businesses are discussed.

IPTV contents are based on MPEG2-TS(Moving Picture Expert Group-2 Transport Stream). The Created content is delivered to each home's Set-Top box through the Internet service network, which will be visible on television through the decoding process. The using and spending of content expanding were quite limited in the other existing lines' devices. For this end, provided methods are to convert MPEG2-TS to other format and then transmit it. These methods are causing not only an overload to the system but also its increasing the hardware resource requirements. In this paper, the MPEG2-TS of IPTV's content using RTP(Real time Transport Protocol) provided by the applicable variety of devices and environmental system, was designed and implemented. Through this paper, the existing MPEG2-TS is providing other devices for distribution and consumption that can give better content to the consumers which means that the QoS(Quality of Service) was enhanced. And, the increased consumption and use of content will help the IPTV business to get more development and activation.

Seamless streaming of multimedia content via heterogeneous networks to viewers using a variety of devices has been a desire for many multimedia services, for which the multimedia contents should be adapted to usage environments such as network characteristics, terminal capabilities, and user preferences. Scalability in video coding is one of attractive features to meet dynamically changing requirements of heterogeneous networks. Currently a new scalable video coding (SVC) is standardizing in the Joint Video Team (JVT) of the ISO/IEC Moving Picture Experts Group (MPEG) and the ITU-T Video Coding Experts Group (VCEG), which will be released as Extension 3 of H.264/MPEG-4 AVC. In this paper, we introduce new technologies of SVC and evaluate performance of it especially regarding on overhead bit-rate and coding efficiency to support spatial, temporal, and quality scalability.

Moving Picture Expert Group(MPEG) is the organization foundedin 1998 to establish the standards for compressing and expressing the multimedia contents. The organization has established the technological standards such as MPEG-1, MPEG-2, MPEG-4 and MPEG-7. As the 3D video related standards, there is Multiview Profile which is included in the MPEG-2 video of 1996. However, as the MPEG-2 multiview profile is the standard for compressing the videos from two viewpoints on the object, it is not enough to meet the requirement of multiviewvideo technology. In addition, it does not have the technology on the viewpoint switching that it does not provide the services such as the user interaction. This paper proposes the structure in which the specific viewpoint can be described for video switching in addition to the current MPEG-4 system.

Game and Animation are considered as two different fields. The definition of animation is "moving picture" and game is a kind of animation which can be controlled by users. Actually, many principles of animation are applied to the production of games, and are even more emphasized in the mobile game contents which are becoming popular these days because of the characteristics of mobile devices such as small screen size. In this paper, we study on the application of the 12 principles of animation through the making of a mobile 3D game called "Fly to the music" and that game is going to be serviced in late 2006 by SK Telecom. Moreover, we studied the differences between 3d mobile game animation and ordinary animation.

In recent years, as network technology develops, the usage of streaming services by users is increasing. However, the complexity of streaming services is also increasing due to various terminal environments. Even when streaming the same content, it is necessary to re-encode the content according to the type of service. In order to solve the complexity and latency of the streaming service, Moving Picture Experts Group (MPEG) has standardized the Common Media Application Format (CMAF). In addition, as content transmission using a communication network becomes possible, the Republic of Korea's Ultra High Definition (UHD) broadcasting standard has been enacted as a hybrid standard using a broadcasting network and a communication network. The hybrid service enables various services such as transmitting additional information of contents or providing user-customized contents through a communication network. The Republic of Korea's UHD transmission standard utilizes MPEG Media Transport (MMT), and Mobile MMT is an extension of MMT to provide mobile network-specific functions. This paper proposes a method of inserting CMAF contents suitable for various streaming services using signaling messages of MMT and Mobile MMT. In addition, this paper proposes a model for content insertion system in heterogeneous network environment using broadcasting and communication networks, and verifies the validity of the proposed technology by checking the result of content insertion.
