With the help of information technology The problem of building a concrete form with a shapeless media is the starting point of presenting information by means of sound. Audio-Visual System using sound as a medium is a method that presents an auditory material visually and has a role of linking different sensory organs. In a sense, Audio-Visual System transfers a non-concrete sensation to a concrete one. Audio-Visual System presentation by late methods using active and non-active images produced by computerized irregular procedures can be limited because of the limited ways of visual output. On the other side, visualization using active images can induce more diverse expressions using sound as a medium. This study suggests a new way of expression in animations using visualization of various auditory materials and sounds built by Audio-Visual System with active images.

방송의 디지털화가 실현되면서 다가오는 21세기는 새로운 방송문화의 창조가 기대된다. 디지털방송은 인프라스트럭처에서 서비스에 이르는 미디어의 변혁이며, 세계적인 규모로서 특히 지역의 구석구석까지 풍요로운 사회생활을 기대할 수 있을 것이다. 이를 보급하기 위해서는 각국의 시책, 인프라의 정비, 기술규격의 표준화, 값싼 고기능 정보단말, 매력적인 서비스를 동시에 병행하여 유저에게 받아들여질 수 있는 프로세스를 창출하는 것이 필요하다. 디지털방송의 전개는 영상$\cdot$음성부호화 기술의 규격표준화를 계기로 위성$\cdot$지상파$\cdot$케이블의 각 전송매체에서 시작하여 현장감이 넘치는 고품질 텔레비전, 다채널, 멀티미디어정보서비스의 실현을 위해 일본$\cdot$미국$\cdot$유럽 각국에서 동시에 활발하게 추진중에 있다. 이와같은 디지털방송서비스를 실현하는데는 오디오 비쥬얼기술과 통신 및 컴퓨터를 융합한 고도의 기술개발이 필요하다. 미쓰비시전기(이하''동사''라 한다)는 새로운 시대를 열기 위하여 방송국시스템, 집배신네트워크, 가정용수신기, 디지털텔레비전용 CODEC, 기간 LSI 등의 개발에 적극적으로 대처하고 있다.

Terrestrial digital multimedia broadcasting (TDMB) is a method of bringing multimedia images, radio, internet, and television to portable devices through terrestrial digital radio transmissions. TDMB related educations being carried out in colleges are focusing on developing firmware which enables users to choose a wanted service. TDMB transmission frame is made up of synchronization channel (SC), fast information channel (FIC), and main service channel (MSC). Services such as video, audio and date are transmitted in the form of subchannel in the MSC. FIC carries information related to each services and subchannels. This paper presents a TDMB frame analysis simulator for analyzing and displaying FIC data on PC. TDMB frame analysis simulator contains functions such as controlling TDMB receiver through USB, establishing the frequency, bringing FIC to PC, displaying ensemble ID and levels, and displaying informations related to services and subchannels. In addition to that, this simulator has a function of being able to store FIC date and subchannel data. This simulator being developed with C++ is expected to be used to view those data visually so that it helps students to understand the TDMB system better and bring about the educational motivation.

In the design of mobile entertainment systems for historical heritage sites, it is important to not only overcome technical challenges imposed by power requirements, computation limits, and connectivity, but to support group experiences and consider users preferences for situated media consumption. Cultural heritage sites provide an opportunity to entertain and educate the public through the use of mobile media. The proposed system implemented on a Java-enabled mobile phone provides both audio and visual content that is tailored by tracking user movement with GPS, collecting various user inputs and demographics, and allowing for socially acceptable eavesdropping via wireless networking. By designing for the spatial, personal, and social considerations of the environment, we aim to help users navigate the diverse topology of the space and consume the vast quantities of historical media.
