- a first high-definition multimedia interface (HDMI) inputter of a first channel configured to receive a first image data signal from an HDMI input connector mounted on a set-top box;
- an HDMI outputter configured to output a signal processed image data signal to an HDMI output connector mounted on a TV;
- a video processor having an input terminal connected to the HDMI input connector and an output terminal connected to the HDMI output connector and configured to receive the first image data signal from the HDMI input connector, perform signal processing on the first image data signal according to a plurality of channels, and output the signal processed first image data signal to the HDMI output connector;
- a controller provided with a second HDMI inputter of a second channel for a video and voice call and configured to receive an HDMI signal through the second HDMI inputter, transmit the received HDMI signal to the video processor, and control the video processor to perform signal processing on an image data signal and a voice data signal that are input through the first HDMI inputter and the second HDMI inputter;
- a wireless communication module connected to the controller and configured to receive the HDMI signal through wireless communication;
- an embedded Mom Call button configured to, upon receiving a power signal for a button, generate a call button ON-signal for a video call and transmit the generated call button ON-signal to the controller through the wireless communication module;
- and
- a multi-sensor module electrically connected to the controller and provided with a built-in camera configured to capture an image of surroundings to generate an image signal and transmit the image signal to the controller,
- wherein the controller is configured to, in response to receiving the call button ON-signal from the embedded Mom Call button, generate a video call request signal for requesting a video call to transmit the generated video call request signal to a previously registered phone number of a smart phone through the set-top box and, in response to receiving a response signal to the video call request signal from the smart phone, perform a video and voice call protocol to enable a video call to configure a communication environment in which the TV and the smart phone perform the video call,
- wherein the controller is configured to transmit the image captured by the built-in camera to the smart phone, receive an image data signal and a voice data signal from the smart phone through the wireless communication module to transmit the image data signal and the voice data signal to the TV through the second HDMI inputter, the video processor, and the HDMI outputter to perform a bi-directional video call between the built-in camera, the TV, and the smart phone, and
- the controller is configured to receive and process a control signal generated by manipulation of the smart phone such that the smart phone performing wireless communication transmits and receives interactive content, generate a response signal to the control signal transmitted from the smart phone, transmit the generated response signal to the smart phone, determine whether the TV is in an on state based on whether a hot plug detect signal is detected among the HDMI signals, determine that the TV is in an off state based on the hot plug detect signal not being detected from the TV, and generate a TV power ON signal and transmit the generated TV power ON signal to the TV.
