Abstract: A system, method and algorithm for performing statistical analysis on an input data source to determine an optimal token size resulting in an increased ratio value is described. Changes to the values of the tokens prior to compression may result in an overall compression increase even if the data source has been previously compressed. Specific techniques for modifying the tokens include varying the base size, rearrangement of the tokens, and modifications by matrix multiplication. After modification of the tokens, compression of the data using one or more lossless compression methods may be performed. The technique may be repeated by using the output of previous compression processes as input to additional entropy and compression optimization.

Abstract: The present invention generally relates to a content delivery system that utilizes editing, caching and compressing to speed the delivery of content from a network, such as the Internet, while conserving bandwidth usage. A local computer sends a request for content to a computer on a first network (the Internet) through a second network (such as an ISP or Intranet). The request is intercepted by a Proxy Server which is coupled to an Editor and Compressor. The Proxy Server returns the requested content to the requestor in a compressed form and in such a manner that the delivery of such content is faster than the current state of the art.
