1. A system for displaying an image having a first level of resolution and being represented by a first set of digital data across a bandwidth-limited transmission medium, comprising:
- reduced resolution generating means for creating plural, successively reduced resolution sets of digital data from said first set of digital data;
a digital storage means for storing said first set of digital data and said reduced resolution sets of digital data;
image display means remote from said digital storage means for visually displaying an image having a selective area;
a transmission medium operatively interconnecting said digital storage means and said image display means;
first control means for selecting an image area on said image display means;
second control means for automatically selecting and transmitting the appropriate one of said reduced resolution sets of digital data related to the size of a selected image area and a desired image resolution; and
,third control means for dynamically adjusting the resolution of the digital data transmitted to the image display means to the desired image resolution of the image area.

Abstract
A system and method for storing image data in a location remote from a display device which uses the data. The system uses plural reduced resolution image data sets and geographical coordination between the image being viewed and the data sets to substantially reduce the bandwidth required to transmit the image data and to shorten the time needed for transmission. Automatic transmission of data needed may be utilized.

7. A system for displaying image data in a display remote from a storage device storing said image data, said image data representing an image of a predetermined size, comprising:
-
a communications medium functionally interconnecting said display and said storage device for the transmission of image data; means for generating and storing at said storage device plural sets of image data, each of the sets representing said image at a different resolution; means for arranging the data within each of said plural sets for efficient storage on said storage device; means for selectively transferring a portion of one set of data along the communications medium from the storage device to the display; and
,means for selecting a portion of the image from among the plural sets to be transferred from the storage device to the display. - View Dependent Claims (8, 9, 10, 11, 12)

13. A method of displaying data on a display which is remote from a storage device storing image data, comprising:
-
(a) providing a display and a storage device remote therefrom; (b) functionally interconnecting the display and the storage device; (c) storing an image at a predetermined resolution in said storage device; (d) generating plural reduced resolution images of said image, each of the plural reduced resolution images having a different resolution associated therewith; and
,(e) selectively transferring a portion of one of the reduced resolution images in response to a request from the display for an image. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21)
