Methods and apparatus for communicating and displaying compressed image data
First Claim
1. A system for processing a compressed image file that describes an image, the system comprising:
- a first computer adapted to create a compressed image tile based on the compressed image file without fully decompressing the compressed image file, the compressed image tile describing a portion of the image;
a second computer adapted to decompress the compressed image tile and display the portion of the image.

Abstract
Methods and apparatus are provided for creating one or more compressed image tiles based on a compressed file that describes a digital image. In particular, the compressed image tiles are created without fully decompressing the compressed file. Each compressed image tile includes data corresponding to a portion of the digital image, and is independent of other compressed image tiles (i.e., may be decompressed without decompressing any other tile). In response to requests to display a desired portion of the digital image at a specific resolution, the compressed image tiles corresponding to the desired portion and the specified resolution are communicated via a band limited communication channel. In this regard, the portions of the digital image may be quickly communicated and displayed, without having to wait for the entire compressed file to be communicated over the band limited channel.
