Abstract

A remote controller and a power control method are disclosed. The remote controller includes a voice recognizer a voice recognizer configured to recognize a voice utterance, a user interface configured to receive a user command; and a controller configured to, when a user command is input through the user interface to enter a voice recognition mode, convert a stand-by mode into an active mode, and convert the active mode into the stand-by mode depending on whether the utterance is recognized within a preset critical time. Accordingly, the remote controller, enabling an operation mode of a voice recognition module which recognizes a user voice utterance to be maintained as an active mode, can reduce power unnecessarily consumed.

Claims

1. A remote controller, comprising:

a communicator;

a voice recognizer;

a user interface; and

a controller configured to;

based on a user command input through the user interface while the remote controller is in a stand-by mode in which a user voice is unrecognizable, convert the stand-by mode into an active mode in which the user voice is recognizable, and

based on receiving a first voice while the remote controller is in the active mode, control the communicator to transmit the first voice to an external display apparatus,

based on receiving a second voice following the first voice while the remote controller is in the active mode of a critical time period, maintain the active mode,

based on not receiving the second voice following the first voice while the remote controller is in the active mode of the critical time period, convert the active mode into the stand-by mode,

based on receiving response information related to the first voice from the external display apparatus after converting the active mode into the stand-by mode, convert the stand-by mode into the active mode,

wherein, in the stand-by mode, the controller is configured to supply a power to the communicator and block power supply to the voice recognizer, and

wherein, in the active mode, the controller is configured to supply the power to the communicator and the voice recognizer.

2. The remote controller of claim 1, wherein the response information is information which notifies that a function is performed by the display apparatus based on control information corresponding to the first voice or a response message is output based on response information received from a dialogue server.

3. The remote controller of claim 1 further comprising:

an output unit,

wherein the controller, based on the remote controller converting from the stand-by mode into the active mode, outputs an alarm message notifying that the stand-by mode is converted into the active mode through at least one of an audio and a video.

4. A power control method in a remote controller, the remote controller comprising a voice recognizer and a communicator, the method comprising:

based on a user command input through the user interface while the remote controller is in a stand-by mode in which a user voice is unrecognizable, converting the stand-by mode into an active mode in which the user voice is recognizable;

based on receiving a first voice while the remote controller is in the active mode, transmitting the first voice to an external display apparatus through the communicator;

based on receiving a second voice following the first voice while the remote controller is in the active mode of a critical time period, maintain the active mode;

based on not receiving the second voice following the first voice while the remote controller is in the active mode of the critical time period, converting the active mode into the stand-by mode; and

based on receiving response information related to the first voice from the external display apparatus after converting the active mode into the stand-by mode, converting the stand-by mode into the active mode,

wherein, in the stand-by mode, a power is supplied to the communicator and power supply to the voice recognizer is blocked, and

wherein, in the active mode, the power is supplied to the communicator and the voice recognizer.

5. The method of claim 4, wherein the response information is information which notifies that a function is performed by the display apparatus based on control information corresponding to the first voice or a response message is output based on response information received from a dialogue server.

6. The method of claim 5, further comprising;

outputting, based on the remote controller converting from the stand-by mode into the active mode, an alarm message notifying that the stand-by mode is converted into the active mode through at least one of an audio and a video.

7. A non transitory computer readable medium storing a power control method in a remote controller the remote controller comprising a voice recognizer and a, the method comprising:

based on a user command input through the user interface while the remote controller is in a stand-by mode in which a user voice is unrecognizable, converting the stand-by mode into an active mode in which the user voice is recognizable;

based on receiving a first voice while the remote controller is in the active mode, transmitting the first voice an external display apparatus;

based on receiving a second voice following the first voice while the remote controller is in the active mode of a critical time period, maintaining the active mode;

based on not receiving the second vice following the first voice while the remote controller is in the active mode of the critical time period, converting the active mode into the stand-by mode; and

based on receiving response information related to the first voice from the external display apparatus after converting the active mode into the stand-by mode, converting the stand-by mode into the active mode,

wherein, in the stand-by mode, a power is supplied to the communicator and power supply to the voice recognizer is blocked, and

wherein, in the active mode, the power is supplied to the communicator and the voice recognizer.
