METHOD FOR DOCUMENT VIEWING
First Claim
1. A method for viewing, on a client-side device, documents requested from a server-side device, the client-side device and server-side device having a communication link therebetween, comprising:
- (a) generating a request from a client-side device to be sent to a server-side device, the request identifying a document;
(b) the server-side device retrieving, in response to receiving the request from the client-side device, the requested document;
(c) the server-side device compressing, using a compression format compatible with the client-side device, the retrieved document into a compressed image;
(d) the server-side device determining that a size of the compressed image is greater than a size of the image rendered on the display;
(e) the server-side device communicating a decompressed image to the client side device when the server side device determines that a size of the compressed image is greater than a size of the image rendered on the display; and
(f) the client-side device displaying the decompressed image.

Abstract
A client-side handheld device requests a server to convert server-side documents into a compression format prior to transmission of said documents to the client. The server retrieves and converts the requested documents to a raster image that is then compressed according to attributes based on information received from the client device in the initial document request. Instead of having to manipulate multiple formats which the original documents are in and supported by the server, the client-side device is preferably optimized in hardware and/or software to support and otherwise take advantage of the requested compression format. The compressed document is then delivered to the client device, in whole or in part, selectively or progressively over time per individual requests prior to displaying the received data to the end-user. Depending on the requested delivery mode, server-side documents are preferably compressed using wavelet compression methods, such as the JPEG 2000 standard, known in the arts. Through such a compression format, documents of sizes (in total bytes) exceeding one or more Megabytes can be compressed down to as small as 30 kilobytes or less.

7. A method for viewing, on a client-side device, documents requested from a server-side device, the client-side device and server-side device having a communication link therebetween, comprising:
-
(a) generating a request from a client-side device to be sent to a server-side device, the request identifying a document, and a section of the document to be sent to the client-side device;
(b) the server-side device rasterizing the requested document;
(c) the server-side device compressing, using a compression format compatible with the client-side device, the rasterized requested document into a compressed image;
(d) the server-side device selecting a section of the compressed image corresponding to the requested section of the requested document;
(e) the server-side device determining that a size of the received compressed image is greater than a size of the image rendered on the display;
(f) the server-side device communicating a decompressed image to the client side device when the server side device determines that a size of the compressed image is greater than a size of the image rendered on the display; and
(g) the client-side device displaying the decompressed image. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14, 15)
