This game machine system includes a set top box 51 as a receiving unit for
receiving digital data distributed using a broadcast system or a
communication system. In a game dedicated device 52, starting of a game
software item is inhibited until a software start enable signal is
received by the receiving unit. Next to the software start enable signal,
data for substitution or insertion for data of part of the game software
is sent. This data can be commercial ads. The game dedicated machine 52
can judge whether or not the commercial ads have been introduced into and
are in operation in the game software and, if the commercial ads are not
in the game software, the game dedicated machine 52 can be made so as to
be out of operation.
