Patent ID: 7212174

Claim:
A method for sharing an application operating on a host computer operatively coupled to a network, said method comprising the steps of: parsing a display area comprising a plurality of pixels each having a value associated therewith into two or more regions to produce a divided display area wherein each region of said divided display area contains a subset of said plurality of pixels; determining if members of said subsets of said plurality of pixels differ from a like number of associateable subsets each having a like plurality of members consisting of associateable pixels each having a stored-value and further stored in a memory, comparing one of said pixels within each of said subsets of said display area to its respective associateable pixel stored in said memory, said one of said pixels from each subset of said display area being a selected pixel located adjacent to another of said two or more regions of said display area; and transferring those of said adjacent regions which border said selected pixel if said selected pixel has a value that differs from said value of said respective associateable pixel and displaying the transferred pixels on a receiving computer at a remote location.
