Method and system for transferring repetitive images over computer networks

Abstract

A method and system is provided for enhancing a reproduction of a recurring image of an first computer on a second computer in a computer network. In order to avoid transferring high color depth high volume of data for recurring images on one computer to another, the recurring image is invoked by a low bit identifier. For example, between a controlling and controlled computer, if a controlled computer detects a first screen image wherein the first screen image having a relative high color depth, it identifies the first screen image by assigning a first identifier (ID). Then, the controlled computer produces a low color depth representation of the first screen image to be stored, and sends the first screen image to the controlling computer along with the first ID. The controlling computer compresses and stores the first screen image along with the first ID. When the controlled computer, by using the stored low color depth representation of the first screen image, detects that a second screen image is a part of the first screen image or is the same as the first screen image, it sends the first ID to the controlling computer for invoking the first screen stored on the controlling computer, and the controlling computer retrieves and displays the stored first screen image.
