Abstract

It is an object of this invention to provide a graphic display apparatus that reduces the amount of CG data transferred from a server through a network and that allows three-dimensional characters displayed at a terminal to move smoothly. It is another object of this invention to provide an AV synchronous reproduction apparatus that can synchronize an image with a score the tempo of which is changed during reproduction. According to this invention, when a server instructs a terminal to graphically display three-dimensional characters, the terminal provides a plurality of motion patterns. The server then transmits scenario data to the terminal, and the terminal operates based on the scenario data to switch scenes for graphical displays. The terminal switches the scenes for graphical displays with a timing for a home position which is common or substantially common to a motion pattern being executed and a motion pattern to be executed next.
