Abstract

본 발명은 단순한 구조를 가진 이미지 데이타 통신 시스템을 제공하고 있다. 이때 필요없는 처리 과정은 삭제되므로 요구된 이미지 데이타는 이미지 데이타를 요구하는 소스의 단자에 빨리 전달되어질 수 있다. 서버(server)와 다수의 단자들은 그 사이에서의 이미다 데이타 통신을 허용하기 위해 서로 연결이 되어 있다. 서버에 제공된 단자 정보 복구 부분은 제1단자로부터 요청된 이미지 데이타가 제2단자로 이미 전달이 되었는지 안되었는지를 판별한다. 판별의 결과가 데이타가 이미 전달되었다는 사실일때 서버에 제공된 이미지 데이타 전송부는 제2단자에 이미지 데이타의 전송을 요구한다. 그리고 제2단자로부터 수신된 이미지 데이타를 제1단자로 전달한다.
각 단자에 제공된 단자 메모리는 이미지 데이타를 저장한다. 그리고 각 단자에 제공된 이미지 데이타 전송부는 서버에서 요청한 이미지 데이타를 단자 메모리에서 판독하며, 그 판독된 이미지 데이타를 서버에 전송한다.

Description

이미지 데이타 통신 시스템
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제1도는 이미지 데이타 통신 시스템에 관한 양호한 실시예를 도시한 블록도,
제2도는 제1도의 이미지 데이타 통신 시스템에서 사용되는 패킷 데이타의 포맷을 도시한 도면.

Claims (4)
