Abstract:
1. An image display apparatus comprising: a monitor apparatus configured to display images, the monitor apparatus including a first power supply switch; and an image processing apparatus including: a tuner configured to receive a compressed and encoded digital television signal, a second power supply switch, and a controller section including a recognizing section configured to recognize the monitor apparatus connected to the image processing apparatus, the image processing apparatus configured to: a remote controller including a third power supply switch arranged therein, the third power supply switch configured to operate any one of the monitor apparatus and the image processing apparatus; wherein each of the monitor apparatus and the image processing apparatus are configured in separate casings; wherein the monitor apparatus is configured to issue a linked authentication Consumer Electronics Control (CEC) vendor command to the image processing apparatus; wherein the image processing apparatus is configured to issue a linked authentication CEC vendor command to the monitor processing apparatus; wherein the monitor apparatus and the image processing apparatus are configured to operate in a linked operation mode, wherein when the monitor apparatus and the image processing apparatus recognize the respectively issued linked authentication CEC vendor command, the monitor apparatus and the image processing apparatus are configured to switch to linked operation mode; wherein when the monitor apparatus and the image processing apparatus are in linked operation mode, upon power on operation of anyone of the first, second and third power supply switches, the controller section is configured to: transmit a power on command in response to the power on operation to the monitor apparatus via the required interface to turn on the monitor apparatus, issue an inquiring command to the monitor apparatus to obtain information on the power state of the monitor apparatus, receive, from the monitor apparatus, information on a state of power supply of the monitor apparatus controlled by the power on command, which is obtained in response to the inquiring command, and ensure that the monitor apparatus has been turned on based on the received information on the state of power supply of the monitor apparatus, and then control turning on the image processing apparatus, thereby, even when anyone of the first, second, and third power supply switches is operated, the controller section controls the power supply of the monitor apparatus and the power supply of the image processing apparatus in operation with each other, in such a way that both power supply states become equal.
