The output and usage rate of audio-visual materials have sharply increased as the information industry advances and diverse archives became available. However, the awareness of the audio-visual archives are more of a separate record with collateral value. The organizations that hold these materials have very weak system of the various areas such as the categories and archiving methods. Moreover, the management system varies among the organizations, so the users face difficulty retrieving and utilizing the audio-visual materials. Thus, this study examined the feasibility of the synchronized management of audio-visual archives by comparing the descriptive elements of the audio-visual archives in internal key agencies. The study thereby examines the feasibility of the metadata element of the organizations and that of synchronized management to propose the effect of the use of management, retrieval and service of efficient AV materials. The study also proposes the improvement of descriptive element of metadata.

최근 정보통신 제품 및 서비스 산업의 발달로 VOD, Teleshopping 등의 멀티미디어 서비스를 위한 사용자 시스템의 개발이 한창이다. 그러나 구현된 제품이 국제 표준과 일치하지 않으면 제품은 시장 경쟁력을 상실하게 된다. 따라서 관련 프로토콜의 특성을 고려한 적합성 시험은 제품 및 서비스의 상호운용성의 확보를 위해 필수적이다. 본 고는 디지털 음향영상 통신 프로토콜로 자리잡고 있는 DAVIC(Digital Audio Visual Council) 표준의 주요 프로토콜에 대한 구현 제품의 체계적이고 효율적인 프로토콜 시험 방법을 조사 분석하고 향후 연구 과제 및 분야를 제시하고 있다.

Recently with the rapid development of data communication products and service industry, the system on behalf of users for multimedia services such as VoD(Video on Demand), Teleshopping are at the height of development, However, if the new style products and services do not conform to the international standard, the products will come to lose the competitive power in the market. Therefore, it is essential to have conformance testing considered the properties of related protocol for the interoperability of the products and services. As a systematic and efficient conformance testing method of new products in respect of the main protocol of DAVIC(Digital Audio Visual Council) standard, this paper presents the protocol test methodology and architecture ; a single protocol stack an the related protocol stacks testing.

3D 산업의 발달과 함께 음원을 통해 현장에서 느낄 수 있는 입체감을 재현하는 실감 음향 기술에 대한 관심 또한 증가하고 있다. 정확한 실감 음향을 구현하기 위해서 헤드폰과 스피커 시스템을 이용한 연구가 활발하게 진행되고 있다. 특히 스피커를 이용하는 실감 음향 연구는 초다채널 스피커를 이용하여 물리적 음장 재현을 목표로 하는 방법과 소채널 스피커를 이용하여 사용자의 특성을 적용한 인지적 음장 재현을 목표로 하는 방법으로 나뉜다. 헤드폰과 스피커를 이용한 기존 연구들이 사용하는 기술들에 대해서 알아보고, 기존 기술의 장점과 단점에 대해서 분석해본다. 이를 통해 사용자 맞춤형 실감 음향 기술의 구현을 위한 연구 방향과 새롭게 적용할 수 있는 기술들에 제시하고자 한다.

While the broadband multimedia technologies have been developing, the commercial market of digital contents has also been widely spreading. Most of all, digital cartoon market like internet cartoon has been rapidly large so video cartooning continuously has been researched because of lack and variety of cartoon. Until now, video cartooning system has been focused in non-photorealistic rendering and word balloon. But the meaningful frame extraction must take priority for cartooning system when applying in service. In this paper, we propose new automatic frame extraction method for video cartooning system. At frist, we separate video and audio from movie and extract features parameter like MFCC and ZCR from audio data. Audio signal is classified to speech, music and speech+music comparing with already trained audio data using GMM distributor. So we can set speech area. In the video case, we extract frame using general scene change detection method like histogram method and extract meaningful frames in the cartoon using face detection among the already extracted frames. After that, first of all existent face within speech area image transition frame extract automatically. Suitable frame about movie cartooning automatically extract that extraction image transition frame at continuable period of time domain.

Sound equipment has developed rapidly as digital technology has quickly matured. Due to this fact, the necessary knowledge and skills are new. Moreover, improvements in digital surrealism in acoustical modeling have increased the challenges facing future audio engineers. Therefore, the necessity of Instruction in the use of sound equipment is needed for the specialist and amateur, alike. However, it is not easy to loam all kinds of sound equipment and systems which are upgraded often. It is necessary to offer a virtual environment that accurately simulates the manipulation and experiences of new sound recording technologies. The purpose of this study was to design a web based virtual operating system for sound equipment technologies which guide user to learn basic principles of usage and production techniques. The virtual simulation system was designed to aggressively implement an actual equipments so that user manipulation will accurately reflect current equipment usage and behavior.

The purpose of this study is to find out the results of synesthesia speech training using similar language for shaping audiobook text. The audiobook text for training uses Tolstoy's work, and uses similar language of tone, tone, pose, speed, intonation, accent, and expression of emotions. The participants who ten visually impaired trainee in H library were selected for qualitative research. Based on the research questions raised in this study, the results are as follows. First, synesthesia training, in which more than two senses of the five senses work simultaneously in voice training for audio book text shaping, produced the result by visualizing the original purpose, meaning, and background of the text. Second, the use of similar language was helpful in the whole process of expressing the meaning of sentence and dialogue for audiobook text shaping. In addition, although there were some differences among the study subjects, they found commonalities that considered tone, pose, and intonation important. Third, the visually impaired have advanced sensory aspects and memory, which resulted in rapid acquisition of metabolism and acceptance of transmission during training. In addition, the teacher's friendly behavior was a very important key mediator in the training process.
