Abstract
According to an embodiment of the present disclosure, a remote control device for transmitting and receiving a control signal to and from a display device may include a Bluetooth circuit configured to establish Bluetooth connection with the display device, an IR circuit configured to output an IR signal, and a controller configured to output an IR signal for controlling the display device or an external device connected to the display device based on information on a video input mode of the display device when Bluetooth connection with the display device is not established.
Claims10
A remote control device for transmitting and receiving a control signal to and from a display device, comprising:
- a Bluetooth circuit configured to establish Bluetooth connection with the display device;
- an infrared (IR) circuit configured to output an IR signal;
- and
- a controller configured to:
- receive IR information related to controlling an external device connected to the display device;
- receiving an input to a button of the remote control device;
- determining whether the Bluetooth connection is established with the display device;
- based on a determination that the Bluetooth connection with the display device is not established, outputting a first IR signal for controlling the external device corresponding to the input button based on determining that a current video input mode of the display device is an external device input mode using a button input history stored in a memory of the remote control device;
- and
- based on a determination that the Bluetooth connection with the display device is established:
- transmitting, to the display device via the Bluetooth connection, information on the input button;
- receiving, from the display device via the Bluetooth connection, an IR key corresponding to the input button;
- and
- outputting a second IR signal according to the received IR key for controlling the external device when the current video input mode of the display device is the external device input mode.
A display system comprising:
- a display device;
- and
- a remote control device configured to transmit and receive a control signal to and from a display device,
- wherein the remote control device is configured to:
- receive IR information related to controlling an external device connected to the display device;
- receive an input to a button of the remote control device;
- determine whether a Bluetooth connection is established with the display device;
- and
- based on a determination that the Bluetooth connection with the display device is not established, outputting a first IR signal for controlling the external device corresponding to the input button based on determining that a current video input mode of the display device is an external device input mode using a button input history stored in a memory of the remote control device,
- wherein based on a determination that the Bluetooth connection is established:
- the remote control device is further configured to transmit, to the display device via the Bluetooth connection, information on the input button;
- the display device is further configured to transmit, to the remote control device via the Bluetooth connection, an IR key corresponding to the input button;
- and
- the remote control device is further configured to output a second IR signal according to the received IR key for controlling the external device when the current video input mode of the display device is the external device input mode.
