The wireless control system of the present invention constitutes a
wireless AV system (101) which forms a wireless transmission network (1)
in which a wireless center unit (102) and a TV main body unit (103) are
connected with each other by a wireless LAN. The wireless center unit
(102) transmits to the TV main body unit (103) control data having, in a
control command, a discrimination code for discriminating between devices
in the wireless AV system (101). The TV main body unit (103) reads out
the discrimination code included in the received control data,
discriminates a device to carry out the control command included in the
control data, and transmits the control data to the discriminated device.
As a result, even when the number of controlled devices that a
controlling device has to control increases, a throughput of the
controlling device for discrimination of control data does not increase,
and therefore the whole system constituted of the controlling device and
the controlled devices can be smoothly operated.
