Device for controlling tv viewing, capable of bi-directional video calling

A device for controlling television (TV) viewing that allows bi-directional video call, the device comprising:

• 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;
• an interface signal processor configured to block or transmit an HDMI image data signal output to the TV according to control of the controller;
• and
• a wireless communication module connected to the controller and configured to receive the HDMI signal through wireless communication,
• wherein the device further comprising a multi-sensor module electrically connected to the controller to receive an HDMI signal,
• wherein the multi-sensor module includes:
• an illuminance sensor configured to measure an intensity of light of surroundings, generate an illuminance sensor value, and transmit the generated illuminance sensor value to the controller;
• a human body detection sensor configured to emit infrared rays to a subject and receive infrared rays emitted from the subject to detect movement of the subject;
• an infrared light emitting diode (LED) configured to emit infrared rays to the subject;
• a built-in microphone configured to collect voice signals of surroundings and transmit the voice signals to the controller;
• and
• a built-in camera configured to capture an image of surroundings to generate an image signal and transmit the generated image signal to the controller,
• wherein the controller is configured to adjust image data signals of a red (R) channel, a green (G) channel, and a blue (B) channel among input image data signals according to the illumination sensor value received from the illumination sensor to adjust a brightness of a screen of the TV,
• the controller is configured to, in response to receiving a response signal to a video call request signal from a 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,
• the controller is configured to transmit an 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, and 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 bidirectional 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.
