An information processing device to enable a user to create a program with visual operations, and to enable the stable implementation of many functions with a small number of devices. In a basic core, a pairing unit executes pairing with a user terminal that executes control for causing functional modules, to exhibit prescribed functions. A transmission information generation unit generates transmission information including: prescribed information to be used by the functional modules, to exhibit the prescribed functions or while exhibiting the prescribed functions on the basis of the control by the user terminal; and information indicating a transmission destination, which is one of the functional modules. A connection unit executes control to superimpose the transmission information on a signal for supplying power to the functional modules in the form of electric current and to transmit the signal to the functional modules.
