Abstract

A real time compression and decompression client-server architecture over bandwidth limited data communications network uses a client application (120) located between a client (130) and a bandwidth limited network (110) and a server (100) located between the bandwidth limited network (110) and an Internet server to send and receive compressed data in an efficient manner across the bandwidth limited network. The native web object formats at the Internet Server are replaced and transformed at the application to a more efficient lossless or lossy compression format. The client application (130) performs the task of decompressing format. The client application (130) performs the task of decompressing and decrypting the new compressed object format from the bandwidth limited network back to the native web object format.
