Abstract

Disclosed is an extended system architecture and means to provide check and/or remittance document image processing at the remote sites of a financial institution. It includes: 1. a document image architecture that is scalable from central MVS/ESA* mainframes to remote OS/2* workstation hosts, 2. an image capture capability that uses a common interface for a family of document processors ranging in speed from 30 to 2400 documents per minute (dpm), and 3. a set of remote image system designs that range from central-site controlled to remote-site controlled.

Extended Image Architecture and Design for a Remote Document Image
System

      Disclosed is an extended system architecture and means to
provide check and/or remittance document image processing at the
remote sites of a financial institution.  It includes:
  1.  a document image architecture that is scalable from central
       MVS/ESA* mainframes to remote OS/2* workstation hosts,
  2.  an image capture capability that uses a common interface for a
       family of document processors ranging in speed from 30 to 2400
       documents per minute (dpm), and
  3.  a set of remote image system designs that range from
central-site
       controlled to remote-site controlled.

      Fig. 1 illustrates the modularity of the Extended Image
Architecture which uses consistent core building blocks to maximize
the re-use of IBM's Systems Application Architecture (SAA*) software
across multiple platforms.  With this approach, the MVS/ESA central
environment can be easily extended to OS/400* and OS/2 environments
for the smaller regional and remote document processing centers.  The
modularity is designed for convolving functions from the complex
multiple components of a large MVS/ESA System down to a single OS/2
workstation providing all of the function, and, handling the total
spectrum between these extreme points.

      Another aspect of the architecture's modularity is the
capability to attach any size document processor (transport and
scanner) to any size host, independent of whether it would be with an
MVS/ESA, OS/400 or OS/2 operating system.  The family of document
processors, ranging from low speed (30 dpm) to high speed (2400 dpm),
uses a common controller (e.g., PS/2*) with standard interfaces
(e.g., LU6.2 Token Ring or System/370* Parallel Channel) to
accomplish
this attachment flexibility.

      Subsequent Figures illustrate a set of remote image system
designs that incorporate the following key elements of the Extended
Image Architecture:
  1.  selected windows of images,
  2.  locally distributed whole images at the remote site,
  3.  robust image record structure (for including coded data, full
       image and image window segments),
  4.  local image log,
  5.  exception image management (manages full-image data base for
       back-up use when image window is insufficient),
  6.  real-time window selection decision (i.e., based on codeline
       recognition), and
  7.  integrated data bridge (i.e., image and coded data is
transmitted
       via a Local Area Network (LAN) bridge between the central and
       remote sites).

      Fig. 2 shows two designs for a remote check/remittance image
system.  The first design called Remote Extended is for the case when
central control of the document processing environment is desired.
The coded data (e.g., document codelines) and image windows are sent
to the central site for processing and stora...
