Abstract

PURPOSE:To allow an AV equipment to be operated in a prescribed way with a simple operation by selecting each AV equipment to be in a prescribed operation when the state detected from each AV equipment is not a state for the prescribed operation and sending a signal controlling each equipment as a remote control code signal. CONSTITUTION:A state detection section 35 detects a state of each AV equipment to detect such that a power supply is switched on or the input mode of a television receiver 13 is in the video mode and sends the result to a 2nd signal processing section 29. When the power supply for the television receiver 13 is not switched on, the 2nd signal processing section 29 gives a command to an instruction generating section 31 to generate an instruction to switch on the power supply for the television receiver 13. Then a remote control signal generating section 33 sends a signal converted into a code corresponding to the manufacture of the television receiver 13 to a remote control signal radiation section 9, from which a signal to switch on the power supply of the television receiver 13 is sent. Thus, a desired operation is implemented to the AV equipment with a comparatively few key operations of twice-thrice.
