일반적인 소프트웨어형상관리 시스템들은 멀티미디어 소프트웨어 개발 환경의 특성 및 특징들을 수용하기에 부족하다. 멀티미디어 소프트웨어 개발 환경은 기본적인 개발 도구 외에 컴포넌트(나 라이브러리)들을 인터액티브하게 조합하고 테스트 할 수 있는 비주얼 프로그래밍 환경을 통한 시뮬레이션과 분석을 반복하면서 개발하는 특징을 가지고 있다. 뿐만 아니라, 시뮬레이션 과정 중에는 유사한 기능을 가진 컴포넌트 중에 적합한 컴포넌트를 빠르고 효과적으로 찾기 위한 방법이 필요하다. 본 논문에서는 이러한 멀티미디어 소프트웨어 개발 환경에서 사용하는 시뮬레이션 도구를 체계적으로 지원해줄 수 있는 비주얼 워크스페이스를 기반으로 한 소프트웨어형상관리 방법과 이러한 방법을 수용할 수 있는 소프트웨어형상관리 시스템을 개발하고자 한다. 또한, 개발된 시스템을 실제 시뮬레이션 도구와 연계하여 소프트웨어형상관리 시스템으로써의 적합성을 확인하고자 한다.

In the field of artistic creation, the iterative development of AI-generated video software has pushed the boundaries of multimedia content creation and provided powerful creative tools for non-professionals. This paper extensively examines two leading AI-generated video software, PIKA Labs and RUNWAY, discussing their functions, performance differences, and application scopes in the video generation domain. Through detailed operational examples, a comparative analysis of their functionalities, as well as the advantages and limitations of each in generating video content, is presented. By comparison, it can be found that PIKA Labs and RUNWAY have excellent performance in stability and creativity. Therefore, the purpose of this study is to comprehensively elucidate the operating mechanisms of these two AI software, in order to intuitively demonstrate the advantages of each software. Simultaneously, this study provides valuable references for professionals and creators in the video production field, assisting them in selecting the most suitable tools for different scenarios, thereby advancing the application and development of AI-generated video software in multimedia content creation.

사물 인터넷과 멀티미디어 협동 작업 환경의 필요성을 기술하고, 그 기반 하에 CoAP 기반 스택에서의 오류 처리에 대해서 제안하였다. 본 논문은 CoAP 기반 게이트웨이 소프트웨어 스택에서의 오류 동기화에 대한 내용을 기술한다. 이 시스템은 CS_EDA, CS_ESA로 구성되어 있다. CS_EDA는 CoAP 기반 게이트웨이 소프트웨어 스택 환경에서 멀티미디어 원격 제어를 위하여 오류를 감지하는 에이전트이다. CS_ESA는 CoAP 기반 게이트웨이 소프트웨어 스택 환경에서 멀티미디어 원격 제어를 위하여 오류를 동기화하는 에이전트이다. CoAP 기반 게이트웨이 소프트웨어 스택에서의 멀티미디어 공동 작업 환경의 관점에서 오류 동기화는 협동 작업에 참가하는 참가자에게 상호작용적으로 오류를 동기화한다.

Recently, the rabid development of information technology has brought enormous changes in education. Consolidation of communications and multimedia technologies are enabling the new educational paradigm such as distance learning and virtual education. Furthermore, many studies in the education engineering field report that teaching using multimedia technologies more enhances students' performance than the traditional instructor-teaching method. However, little research regarding the education using multimedia has been done in the MIS filed. None of multimedia-related studies could be found in the top-ranked MIS journals published in Korea for the last five years, and only a few studies were found even worldwide. In this regard, the purpose of this study is to investigate which features of multimedia software are most important to enhance the teaching results of students. From the previous research, we found out the specific features of the educational multimedia software which are considered to affect the students'performance, and defined the research variables related to those educational software features. And, based on the constructivism and motivation theory of the education engineering field a theoretical research model and research hypotheses were developed. Perceived usefulness of the class and a student's perceived interests in the class were used as surrogate variables to measure teaching performance. Total 277 students participated separately in one of the two multimedia classes which have continued for three weeks. One was C programming language class and the other was multimedia CD-title development class. Each student listened for the multimedia session of the class using multimedia software and, at the end of the multimedia session, answered the survey questionnaire. The results of the study show that motivation to the class and the contents of education were statistically significant to the students'performance in the class. That implies, not only in the traditional instructor-teaching method but also in the multimedia class, that the contents of education itself and student's motivation to the class are most important to raise instructional results.

Recently, flash memory is becoming popular as storage system to store and retrieve multimedia files. However, there are few researches about multimedia file system for flash memory based storage devices. We have been designing and developing a novel multimedia file systems for flash memory. In this paper, we describe the semantics of real-time retrieval of multimedia data and present scheduling scheme to guarantee the real-time requirements in our multimedia file system.

Developing tailor made Multimedia courseware ensuring effective implementation of instruction strategies is a challenge that manifests in myriad problems of software design and coding. In this paper an attempt has been made to analyse and identify coding and implementation problems, in the backdrop of using two different multimedia software development tools i.e. Visual Basic and Toolbook, which underpin the development and effectiveness of use of multimedia courseware. Solutions to such problems have been discussed in context of Tool book. The examples presented in this paper are based on the experience of designing and implementation of two large scale professional quality Multimedia courseware development projects.

We address an integrated multimedia framework based on a software agent platform for context-aware multimedia computing. We adopt the FIPA (Foundation for Intelligent Physical Agents) platform which provides agent communications and management mechanisms. In order to express context information, we use MPEG-21 metadata for describing user characteristics and usage environment. We encapsulate such context information as a FIPA message to be delivered between agents. Based on context information, appropriate multimedia content delivery becomes possible. We present our system implementation with a use case scenario and show that our proposed framework is effective for context-aware multimedia computing so that personalization of multimedia consumption can be possible.

In a motion estimation method for use in encoding a moving picture, a full-pixel motion vector is estimated by stochastically sampling a pixel to be processed in a predetermined-sized block of a previous frame or a next frame as a reference frame for each of a plurality of equal-sized blocks in a current frame. Then, a half-pixel motion vector is estimated based on the full-pixel motion vector. Accordingly, both the calculation amount and the calculation time required for the motion estimation are effectively reduced. Further, it can be prevented that the hardware becomes complicated. .
