<p><P>PROBLEM TO BE SOLVED: To generate display data transmitted to a client device at high speed while reducing the load of CPU. <P>SOLUTION: The server device for computer system configured to transmit display data generated in the server device to the client device to display it on its display screen, comprises a current display memory area 107a storing current screen display data transmitted to the client device; a scaling circuit 101c for changing the magnification of the current screen display data; a tile division determination circuit 101d dividing the magnification-changed current screen display data to a plurality of display areas; and a comparison/compression circuit 101e comparing the current screen display data with previous screen display data transmitted to the client device for each display area divided by the tile division determination circuit 101d, and determining whether both the display data are differed or not. Display data of a display area for which the difference is determined by the comparison/compression circuit 101e is transmitted to the client device. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
