Abstract

A system and method for compressing a data set. The method comprises the steps of: (i) requesting a data set from a server to be sent to a user, (ii) determining the size of the data set to be sent, (iii) compressing the data set, (iv) assigning a compression flag to the compressed data set, (v) sending the compression flag and compressed data set to the user, (vi) inspecting the data set for compression, (vii) uncompressing the data set; and (viii) processing the data set. Alternatively, upon determining the size of the data set to be sent, assigning an uncompressed flag to the data set, sending the uncompressed flag and data set to the user, inspecting the data set for compression, and processing the data set. In another alternative embodiment, upon determining the size of the data set to be sent, sending the uncompressed data set to the user, inspecting the data set for compression, and processing the data set.

Claims

1. A heuristic in-stream data compression system, which comprises:

a first computer device;

a second computer device with a heuristic compression decision logic system that compresses a data set for transmission when an amount of time required to compress, transfer and uncompress the data set is less than the amount of time to transfer the data set without the compression; and

communications system linking the first computer device to the second computer device.

2. The system set forth in claim 1 wherein the first computer device is a desktop computer.

3. The system set forth in claim 1 wherein the communications system is a land-based telephone system.

4. The system set forth in claim 1 wherein the communications system is a satellite based communications system.

5. The system set forth in claim 1 wherein at least one of the linkages between the input device ad the heuristic system is wire-based.

6. The system set forth in claim 1 wherein at least one of the linkages between the input device and the heuristic system is fiber optic based.

7. The system set forth in claim 1 wherein at least one of the linkages between the input device and the heuristic system is wireless.

8. The system as set forth in claim 1 wherein the heuristic compression decision logic system assigns a flag to the data sets the flag having a first condition when the data set is compressed and a second condition when the data set is uncompressed.

9. A system comprising:

a first communication system;

a second communication system; and

a communications infrastructure linking the first and second communication systems, wherein at least one of the first and second communication systems has a heuristic compression decision logic system that compresses data when an amount of time required to compress, transfer and uncompress the data is less than the amount of time to transfer the data without the compression.
