<P>PROBLEM TO BE SOLVED: To efficiently recover a communication terminal in a case where a part of image data transmitted from a server device to the communication terminal is missed in the middle of transmission. <P>SOLUTION: Each time display contents on a display unit are switched, a server device 10 generates image data indicating display contents after switching in respective display sizes of XGA, SVGA and VGA and multicast-transmits a group of block image data by resolutions obtained by dividing each of image data items to a communication terminal 30-k. In a case where block image data of XGA are missed in the group of block image data by resolutions transmitted from the server device 10, the communication terminal 30-k interpolates the missed portion using block image data of SVGA or VGA representing the same block image and switches display contents on the display unit based on the image data of XGA in which the missed portion is filled by the interpolation. <P>COPYRIGHT: (C)2009,JPO&INPIT |
