MODELISATION METHOD OF THE DISPLAY OF A REMOTE TERMINAL USING MACROBLOCKS AND MASKS CARACTERIZED BY A MOTION VECTOR AND TRANSPARENCY DATA

摘要

In process for modeling a display coming from an application on a server, the display being destined for a remote terminal, the display is modeled to compose an image according to display information coming from the application by stacked layers, each layer consisting of pixels and being associated with a corresponding first alteration data set, each pixel being characterized by a transparency factor of the pixel; the first alteration data set indicating characteristics of the layer connected with the alterations performed by the application, the resulting image consisting of image pixels and being associated with a second alteration data set, the second alteration data set indicating whether the image was altered due to the modification of the layers by the application, the image pixels being composed of the superimposed corresponding pixels of the layers.
