In step S304 of FIG. 3, a determination whether to power on the display apparatus is made. When the display apparatus 190 is to remain in a power off state, the method proceeds to step S305 of FIG. 3.
Referring to FIG. 3, the control unit 110 may detect status information (e.g., power on/off) of the connected display apparatus 190. The control unit 110 may recognize the power on/off of the display apparatus 190 by using the consumer electronics control (CEC) function. The CEC is a control protocol using one (e.g., pin 13, which may be a different pin) of a plurality of pins included in an HDMI. The user may use the remote controller 50 to control an apparatus (e.g., the broadcast receiving apparatus 100 and the display apparatus 190) connected through the HDMI using the CEC.
The CEC function may include, for example, one touch play, system standby, tuner preset transfer, one touch record, timer programming, system information, or tuner control in addition to the power on/off. It will be readily understood by those skilled in the art that the CEC function is not limited to the aforementioned functions as a version is updated. In addition, the CEC may be referred to by various names depending on a manufacturer of the apparatus.
When the control unit 110 determines whether to power on the display apparatus 190 connected to an HDMI port 161 of the input/output unit 160, the control unit 110 may allow the display of the power on/off of the display apparatus 190 on the display unit 150. For example, when the display apparatus 190 is powered off, the display unit 150 may display “TV off” (150c) through control by the control unit 110. Alternatively, when the display apparatus 190 is powered on, the display unit 150 may display “TV on” (150e; referring to FIG. 5A) through control by the control unit 110.
When the power on/off of the display apparatus 190 (e.g., the status information of the display apparatus 190) connected to the HDMI port 161 of the input/output unit 160 is detected, the control unit 110 may store the detected status information of the display apparatus 190 in a storage unit.
