Abstract
A server receives an update image for transmission to a client and encodes and compresses the update image data using a progressive encoding scheme. In one embodiment, the image data is encoded using progressive JPEG encoding and then into a base64 text string. When insufficient network bandwidth is available to transmit all of the image data for the update image, the server transmits only a first portion of the encoded image data, which is sufficient to fully reproduce the original update image but at a lower quality. When more network bandwidth becomes available, an additional portion of the encoded image data is transmitted to the client. The client is able to append the additional portion to the first portion to refine the image represented at the client. This mechanism may be implemented using unmodified web browsers and servers to remote a computer graphical user interface display.
