1 is a view for explaining a conventional power control method.

When a control signal (IR signal) for controlling the TV 110 is lost or disturbed by an obstacle, the power of the TV 110 and the set-top box 120 is out of sync.

In order to synchronize the power so that the power of the TV 110 is turned on or off at the same time when the power of the set-top box 120 is turned on or off, the HDMI-CEC setting must be turned on in each device of the TV 110 and the set-top box 120. It is generally possible to use it.

The HDMI-CEC function provided by the TV 110 has a different name for each manufacturer of the TV 110, making it difficult for a user to understand and access. For example,'LG' is'SIMPLINK','Samsung' is'Anynet+','SONY' is'BRAVIA Sync', and so on.

In the case of a product in which the HDMI-CEC function is deactivated or does not provide the HDMI-CEC function, the remote control 130 processes power to the TV 110 and the set-top box 120 at the same time.

The HDMI-CEC feature enables synchronization of control over device operations, such as device play and stop, start and end.

2 is a flowchart illustrating a method of operating a set-top box for power synchronization between a set-top box and a display device according to an embodiment.

In step 430, the TV may change the setting of HDMI-CEC. In an embodiment, the TV may synchronize the settings of the set-top box and the HDMI-CEC by referring to the setting information of HDMI-CEC included in the received device information of the set-top box. In the embodiment, since the HDMI-CEC setting of the set-top box is changed to OFF, the HDMI-CEC setting of the TV may be changed to OFF.

In step 440, the set-top box may set the HDMI-CEC setting from OFF to ON.

In step 450, the set-top box may transmit device information of the set-top box to the TV. In an embodiment, transmission may include a protocol (ExtraInfo=F100) for changing the setting of HDMI-CEC to ON.

In step 460, the TV may change the setting of HDMI-CEC. In the embodiment, since the HDMI-CEC setting of the set-top box is changed to ON, the HDMI-CEC setting of the TV may be changed to ON.
