PROBLEM TO BE SOLVED: To provide a system for transferring still picture with sound data that can display or reproduce desired image data and sound data corresponding to the image data in a fixed time within a decided range at all times independently of a flexible processing speed or communication speed even when all touch panel attached slave terminals access a network server. SOLUTION: In the system consisting of a network server 1, the touch panel attached slave terminals 21-29 that use touch panels to make communication with the network server and to display a desired picture, and a control unit 3 that conducts data transmission reception and protocol conversion or the like between the network server and the touch panel attached slave terminals, when the touch panel attached slave terminals display images, the system periodically broadcasts the image and sound data corresponding to the image to which image number data and touch panel coordinate information are attached, and the touch panel attached slave terminals select and acquire a desired image on the basis of the image number data and the coordinate information and display or reproduce the image and the sound in a fixed time within a decided range. |
