Abstract

A system comprise a management section, a plurality of terminal sections and a coaxial cable. The management section is provided with a predetermined number of video game units and video recorders. The management section further comprises a memory for storing a plurality of video game programs. Each of the video game units executes a video game program to generate a first audio and video signal varying in response to a control signal received from a terminal section. Each of the video recorders storing a plurality of video movies generates a second audio and video signal associated with a video movie. A user of a terminal section selects a desired service from the video games and the video movies. When a video game is selected, the video game program is downloaded into the available game unit provided in the management section. The game unit runs the game program in response to the control signal received from the terminal section where the user is operating a keypad. The video images and sound varying in response to the control signal is transmitted from the management section to the terminal section through the coaxial cable.
