Abstract: An RF remote control paired with a first device can be paired with a second device connected to the first device via HDMI-CEC by an easy user operation. A pairing method uses a system including a television receiver (1) as the first device, a moving-image playback device (3) as a second device connected to the first device, and a remote control (5) having been paired with the first device. The pairing method includes first to third steps: the first step of transmitting the identification code of the remote control (5) from the first device to the second device, the identification code being registered in the first device; the second step of transmitting a pairing code from the second device to the first device; and the third step of transmitting the pairing code from the first device to the remote control (5).

Abstract: It provides a video display system capable of effective control of power consumption, safe power-off operation, and resetting from a hang-up state by properly setting power supply to a plug-in module in accordance with the operational request and operational status of a digital broadcast receiving device and the plug-in module, a display device, a plug-in module, and a plug-in module power control method. Each of the digital broadcast receiving device and plug-in module includes an authentication part for equipment authentication thereof, CEC communication part for control signal communication, and a video audio transmitter receiver. The digital broadcast receiving device serves for switching the module power supply part for power supply to the plug-in module from standby power to main power in accordance with the control signal after equipment authentication is obtained for the plug-in module.
