Method for priority transmission and display of key areas of image data
View Patent ↗A method and an apparatus for selecting, prioritizing, saving, and receiving image data are disclosed. Portions of an image can be selected and the selected portions assigned priorities using preferred embodiments of the present invention. The prioritized image portions can then be saved in a prioritized graphics file. The image can be saved in any graphics file format. When a user accesses the prioritized graphics file, the highest priority portions of the image will be sent to and received by the user first. These highest priority portions will then be displayed to the user. Lower priority portions will subsequently be sent and received until the entire image is displayed to the user. This allows the areas of higher priority to be seen by the user before the user sees areas of lower priority.
1. A method for transmitting a graphics file from a transmitting computer and receiving the graphics file on a receiving computer, the method comprising the steps of:
a) performing the following steps on the transmitting computer:
i) selecting at least one image transmission portion of the graphics file;
ii) assigning a priority to the selected at least one image transmission portion to create a prioritized graphics file; and
iii) transmitting the prioritized graphics file across a network such that higher priority image transmission portions are transmitted before lower priority image transmission portions;
b) performing the following steps on the receiving computer:
i) receiving a first image transmission portion of the prioritized graphics file;
ii) translating the first image transmission portion into image data;
iii) determining the location of the first image transmission portion; and
iv) transferring the image data and the location to an image viewer such that the image viewer can display the first image transmission portion at the location,
wherein the step of transmitting the prioritized graphics file across a network such that higher priority image transmission portions are transmitted before lower priority image transmission portions further comprises the following steps:
A) simulating transmission and reception of the first image transmission portion of the prioritized graphics file;
B) translating the first image transmission portion into image data;
C) determining the location of the first image transmission portion;
D) transferring the image data and the location to an image viewer such that the image viewer can display the first image transmission portion at the location;
E) waiting a delay; and
F) repeating steps A through E in each additional iteration of one or more additional iterations of steps A through E, such that the first image portion is stepped to the next image portion of the prioritized graphics file in the first additional iteration and the next image portion of the prioritized graphics file is sequentially stepped in each subsequent additional iteration, until the entire prioritized graphics file has been transmitted and received.
2. The method of claim 1 wherein the step of translating the image transmission portion of the prioritized graphics file into image data further comprises the step of decompressing the image transmission portion of the prioritized graphics file.
3. The method of claim 1 further comprising the following step that is performed on the transmitting computer:
iv) saving the prioritized graphics file in a prioritized graphics file format.
4. The method of claim 3 wherein the prioritized graphics file format comprises joint picture experts group format, graphics interchange format, or bitmap format.
