US Patent 8007362 Method of displaying multiple kinds of independently processed display data

A terminal apparatus executes different kinds of network games provided by a server group. The user of the terminal apparatus can register other users who become acquainted with the user through network games in a friend list provided for each user. While the terminal device runs different game programs for different kinds of games, the terminal apparatus runs a common friend list program regardless of the game types. When the display of a game image is set to a window mode, the friend list program displays a friend list in a friend list window that is set separate from a game window. When the display of a game image is set to a full-screen mode, the friend list program displays a friend list synthesized with the game image in the form of a semi-transparent image.
