Abstract

In this paper, we propose an architecture of multimedia communication terminal that can e used in broadband ISDN environments. To design and implement the multimedia communication terminal, we analyzed the structure of multimedia terminals and the types of services which is recommended by public and private standard or ganization, such as ITU-T, Digital Audio-Visual Council(davic) and ATM Forum. The multifunctional communication terminal designed in this paper could allow inter-working between existing communication terminals on the heterogeneousnetwork and accept current and advanced multimedia communication application flexible. An implemented terminal is consisted of the multimedia processing board and the ATm interface board that is installed in PCI bus on personal computer. The integrated service multimedia communication terminal that is implemented supports retrieval, distributive and conversational communication service simultaneously. And then we performaned functional module test according to the individual communication services.

본 논문은 광대역 ISDN에서 사용될 수 있는 멸티미디어 통신단말의 구조를 제안하였다. 제안한 구조는 ITU-T, Digital Audio-Visual Council(DAVIC), A TM Forum 등의 국제, 사설 표준기구에서 권고하고 있는 멀티미디어단말 및 서비스를 분석한 결과이며, 기존 통신단말과의 연동을 보장하며, 현재 및 미래의 멀티미디어 응용서비스에 유연하게 대처할 수 있는 구조를 갖도록 하였다. 제안한 구조에 따라 설계된 서비스 통합형 멀티미디어 통선단말은 범용 PC에 탑재되는 멸티미디어 처리보드와 ATM 접속보드로 나누어 구현하였다. 구현된 서비스 통합형 멸티미디어 통신단말은 검색, 분배형 통신서비스와 대화형 통신서비스를 동시에 제공하는 것이 가능하며, 이에 따르는 서비스 별의 기능시험을 수행하였다.
