Referring to fig. 3, the control unit 110 may detect status information (e.g., power on/off) of the connected display device 190. The control unit 110 may recognize power on/off of the display device 190 by using a Consumer Electronics Control (CEC) function. CEC is a control protocol using one of a plurality of pins (e.g., the pin 13, which may be a different pin) included in HDMI. The user can control devices (e.g., the broadcast receiving device 100 and the display device 190) connected by using the HDMI of CEC using the remote controller 50.
In addition to power on/off, CEC functions may include, for example, one-key play, system standby, tuner preset transmission, one-key playback, timer programming, system information, or tuner control. Those skilled in the art will readily appreciate that the CEC function is not limited to the above-described functions as versions are updated. In addition, CECs may be referred to by various names depending on the manufacturer of the device.
When the control unit 110 determines whether to power on the display device 190 connected to the HDMI port 161 of the input/output unit 160, the control unit 110 may allow the power on/off of the display device 190 to be displayed on the display unit 150. For example, when the display device 190 is powered off, the display unit 150 may display "TV off (TV off)" (150c) by the control of the control unit 110. Alternatively, when the display device 190 is powered on, the display unit 150 may display "TV on" (150 e; refer to FIG. 5A) by the control of the control unit 110.
When power on/off of the display device 190 (e.g., state information of the display device 190) connected to the HDMI port 161 of the input/output unit 160 is detected, the control unit 110 may store the detected state information of the display device 190 in the storage unit.

Referring to fig. 5A, the control unit 110 of the broadcast receiving apparatus 100 may recognize power-on of the display apparatus 190 by using a Consumer Electronics Control (CEC) function.
The video 190a displayed on the screen of the display device 190 may be different from the decoded video of the audio channel (e.g., channel number 632) selected by the broadcast receiving apparatus 100. For example, the video 190a displayed on the screen of the display device 190 may be a moving photograph corresponding to the content stored in the storage unit. Alternatively, the video 190a displayed on the screen of the display device 190 may be a video received by another tuner unit (not shown).
For example, when the display device 190 is powered on, the display unit 150 may display "TV on" (150e) by the control of the control unit 110.
Referring to fig. 5B, the control unit displays a popup on the display device 190.
When the display device 190 is powered on, the control unit 110 displays a popup 191 on the screen of the display device 190 to select an audio output mode of the broadcast receiving apparatus 100.
The items of the popup 191 may include "STB audio only" (191a) in which only the broadcast receiving apparatus 100 outputs audio, "TV audio on" (191b) in which both the broadcast receiving apparatus 100 and a built-in speaker (not shown) of the display apparatus 190 output audio, and "TV audio/video on" (191c) in which the broadcast receiving apparatus 100 outputs audio and the display apparatus 190 outputs audio, video, and/or additional information. Those skilled in the art will readily appreciate that the audio output modes 191a to 191c included in the popup 191 may be changed according to the function or structure of the broadcast receiving apparatus 100 and/or the display apparatus 190.
The user selects one of the audio output modes (e.g., 191a) using the navigation keys 53 and/or the confirmation keys 54 of the remote controller 50. The control unit (not shown) of the remote controller 50 may output a third control signal corresponding to the selected audio output mode (e.g., an output mode in which only the broadcast receiving apparatus outputs audio) to the broadcast receiving apparatus 100.
