In the terminal B, the game information received by the communication unit 100 is transferred to the game execution unit 108, and a game image is displayed as necessary (1300). Details of step 1300 will be described later with reference to FIG. The above operations are operations when game information is transmitted from the terminal A1000 to the terminal B1100 via the server 2000. Conversely, when game information is transmitted from the terminal B 1100 to the terminal A 1000 via the server 2000, the operation is as follows. The terminal B 1100 transmits the game information to the server using the communication unit 100 (1300). The server acquires the game information acquired through the communication unit 200 using the transfer unit 205, and transmits the game information to the terminal B indicated by the connection ID acquired in step 2003 (2008). In the terminal A1000, the game information received by the communication unit 100 is transferred to the game execution unit 108, and a game image is displayed as necessary (1300). As described above, the operation of transmitting game information from both the terminal A and the terminal B to the opponent is realized.

  When the end of the battle game is instructed from the input device 101, the terminal A1000 (1004) transmits a disconnection request including the terminal ID, game ID, and connection ID to the server (1005), and the terminal B1100 ( 1104) A disconnection request including the terminal ID, game ID, and connection ID is transmitted to the server (1105). The server receives the disconnection request (2009), notifies the terminal A and terminal B corresponding to the connection ID that the line is disconnected, and transmits the terminal ID, game ID, and connection ID, respectively. (2010). In terminal A, the line corresponding to the connection ID is disconnected (1006) and the process ends. In terminal B, the line corresponding to the connection ID is disconnected (1106) and the process ends. As a result, the terminal 1 can communicate with the opponent by text, video, voice, and music while playing a battle game using inter-terminal network communication.

  Next, the input information transmission / reception process 1200 will be described with reference to FIG. First, when a line is connected (1003), character input from the key / pad 102 of the input means 101, image information from the camera 103, audio information and music information from the microphone are acquired (1201). If there is no input, the process proceeds to an input information receiving step (1250) via a line. It is determined whether the input information is input for a game or chat (1204). If the input information is for a game, it is transferred to the game execution means 108 of the terminal 1 and the process proceeds to step 1250. If it is input information, the input information is transmitted to the line indicated by the connection ID received in step 1003 or step 1103 via the communication means 100 (1207), and the process proceeds to step 1254. In step 1250, input information is received from the terminal corresponding to the connection ID using the communication means (1250). If there is no reception information, the input information transmission / reception process 1200 is terminated, and the process proceeds to the game information transmission / reception / display process 1300. In step 1250, if there is received information, it is determined whether or not it is for a game (1252), and if it is for a game, the game execution means 108 is transferred to step 1201 (1256). If the received information is input information, first, the input information transmitted in step 1207 is acquired (1254), and then the input information received in step 1250 is acquired (1255). The acquired input information is once merged and then sorted in chronological order (1256), chat information to be displayed in the chat information display area 307 is created based on the input information (1257), and the process proceeds to step 1201. Thereby, the function which transmits input information to other terminals, and the function which acquires the input information which other terminals transmitted, and convert it into chat information are realizable.

  Next, the game information transmission / reception / display processing 1300 will be described with reference to FIG. First, the game is executed by operating the game execution means 108 (1301).
