Abstract
An electronic mail on which a control command is interpolated is transmitted through a public line, received by a modem section of a gateway, converted to digital data, and supplied to a control section. A CPU of the control section stores the received electronic mail in a RAM, and extracts the control command contained in the electronic mail. The CPU supplies a control signal corresponding to the control command to an interface section. The interface section controls an IR transmission section to transmit a signal corresponding to the control signal supplied from the CPU or outputs a signal through a connection line, and controls a video deck.
