Abstract: The background is a office background consisting of right-half portion of the background and a left-half portion of the background. By loading just one image, both the backgrounds and can be displayed. The event information can be constructed and output by loading (reading) the speakers' images and messages, and by combining the background images with them. Advantages of the invention include that user stress is minimized when loading the information.

Abstract: Double registration or improper registration of the data of participating teams is prevented in an online-participation game system. Provided is a data communication method for game systems in which game meets are carried out by sending transmission files including data of each team to a server from each of a plurality of game terminal devices, and by thus simulating a competition among the teams, the above-mentioned method comprising: a process wherein the game terminal devices generate transmission files including an identification code (login ID) and game data and send the files to the server; and a process wherein the server checks the identification code of the transmission files received and appends the transmission files received to a registration file for the game meet, in the case when the files do not comprise identification codes identical to those in the accepted transmission file group.
