IMAGE DISPLAY APPARATUS, MONITOR APPARATUS AND IMAGE PROCESSING APPARATUS

摘要

According to our invention, linked operation between a monitor apparatus for displaying images, and a set-top box for transmitting image signals to the monitor apparatus via a required interface, can be achieved properly, even if both units are constructed in casings separate from each other. The monitor apparatus uses a CEC line to transmit a CEC vendor command including at least a code associated with unit information, and the set-top box apparatus transmits the CEC vendor command including at least the code associated with the unit information. Upon receiving the vendor command from the set-top box apparatus, the monitor apparatus switches to the linked operation with the set-top box.

主权项

1. A monitor apparatus connected to an image processing apparatus via a given interface, the apparatus configured to display an image based on an image signal input from the image processing apparatus via the given interface, the monitor apparatus comprising:
a communication unit including a transmitter and a receiver, wherein when an operation for controlling a power is performed, the communication unit is configured to transmit a first command, according to the operation, to the image processing apparatus via the given interface, and to receive a second command via the given interface, the second command issued from the image processing apparatus in response to the first command; and a controller configured to control a power of the monitor apparatus in accordance with the second command received by the communication unit, wherein when the communication unit receives from the image processing apparatus a third command for inquiring about a power on/off status of the monitor apparatus whose power is controlled by the first command, and the communication unit is configured to transmit to the image processing apparatus, via the given interface, a fourth command indicative of the power on/off status of the monitor apparatus, in response to reception of the third command.
