Paper Abstract

We have developed a document station for automated entry and remote retrieval of image documents, and we present experimental results on remote retrieval via an integrated services digital network (ISDN). The document station consist of a UNIX workstation, a 130 mm rewritable magneto-optical disk subsystem, a code/decode board, character-recognition hardware, and a high-speed image scanner. This station can store 300,000 black-and-white A4 pages at 5.0 seconds per page. The experimentally measured time for retrieving one page at a remote terminal is 1.5 seconds within a 10 Mbps local-area network (LAN) and 2.0 seconds within a 1.5 Mbps ISDN.
