Abstract
An improved karaoke network system that allows a user to select and obtain desired information through an interface while a message is displayed between intermissions of karaoke performances. Data files for karaoke performance, displaying messages, and displaying data selection menus are written in a common structure. Each of the data files includes an action region that contains link data. The data files are associated with one another by the link data contained in the action regions of the data files. A chain of related data files are executed by a menu selection operation or a key input operation by the user for performing karaoke performance and displaying messages and data selection menus.
