1. A method for providing JPEG 2000 compressed image data, containing one or more tiles and one or more precincts, for subsequent transmission to a display, comprising the steps of:
- storing the image data in a codestream, said codestream including a first section having a minimum resolution level of image information of an image using a resolution level-layer-component-position progression ordering and a second section having a maximum resolution level of image details of all of said image using a component-position-resolution level-layer progression ordering.

Abstract
A method and system for displaying an image, includes steps and means for: storing image data in a manner that enables retrieval of different spatial regions of an image at different fidelities; determining an viewer'"'"'s point of gaze on a display; retrieving image data for each spatial region of an image at a fidelity that is a decreasing function of the distance of the regions from the point of gaze; and displaying the retrieved image data on the display.

6. A method for storing JPEG 2000 compressed image data, containing one or more tiles and one or more precincts, for subsequent transmission to a display, comprising the steps of:
-
storing first data having a minimum resolution level of image information using a resolution level-layer-component-position progression ordering; and storing second data having a maximum resolution level of image details using a component-position-resolution level-layer progression ordering; and further comprising the step of; producing a lookup table that associates a spatial location with a byte-count offset for the start of the data packets for each precinct in each tile.

7. A method for providing compressed image data, containing one or more tiles and one or more precincts, comprising the steps of:
-
a) storing first data that represents a minimum resolution level of image information in a first section of a codestream; b) storing second data that represents remaining resolution levels of image details in a second section of said codestream, using a component-position-resolution level-layer progression ordering; c) prioritizing a plurality of data packets of said stored second data; and d) transmitting, in order, said first section and at least part of said plurality of prioritized data packets of said stored second data. - View Dependent Claims (8, 9, 10, 11)

12. A method for storing compressed image data, containing one or more tiles and one or more precincts, for subsequent transmission to a display that is viewed by an observer having a point of gaze, comprising the steps of:
-
a) storing first data that represents a minimum resolution level of image information; b) storing second data that represents remaining resolution levels of image details using a component-position-resolution level-layer progression ordering; and c) producing a lookup table that associates a spatial location with a byte-count offset for the start of the data packets for each precinct in each tile.

13. A method for providing a digital image as compressed image data containing one or more tiles and one or more precincts, comprising the steps of:
-
storing first data of the digital image in a first section of a codestream; and storing second data of said digital image in a second section of said codestream, using a component-position-resolution level-layer progression ordering, said first data and said second data being differently ordered, said second data being higher resolution image information than said first data. - View Dependent Claims (14, 15, 16, 17)

18. A method for storing a digital image as compressed image data containing one or more tiles and one or more precincts, comprising the steps of:
-
storing first data of the digital image; and storing second data of said digital image using a component-position-resolution level-layer progression ordering, said first data and said second data being differently ordered, said second data being higher resolution image information than said first data; and further comprising the step of; producing a lookup table that associates a spatial location with a byte-count offset for the start of the data packets for each precinct in each tile.
