## Abstract

A television viewing control apparatus includes a distance setting unit, a time setting unit, an ultrasonic sensor, a mounted wireless communication module, and a control unit to perform control to regulate television viewing when a distance between a viewer and the television is measured and the viewer views the television at a position within a set distance or when a remote control signal is received from a smartphone over a wireless network.

## Claims

### Claim 1

A television viewing control apparatus (100) comprising:
a first digital interface connector provided in a digital image source (200);
a second digital interface connector provided in a television (210);
a distance setting unit (140) setting a viewing distance between the television (210) and a viewer;
an ultrasonic sensor (150) measuring a viewing distance between the television (210) and the viewer;
an interface signal processing unit (110) receiving a digital image data signal from the first digital interface connector to process the digital image data signal for each of multiple channels and outputting the resulting signal to the second digital interface connector; and
a controller (104) storing distance information set by the distance setting unit (140) and controlling the interface signal processing unit (110) to block the digital image data signal output from the first digital interface connector to the second digital interface connector when the viewing distance measured by the ultrasonic sensor (150) is within the viewing distance set by the distance setting unit (140),
wherein the television viewing control apparatus (100) further comprises a time setting unit (142) setting a viewing time that the viewer is allowed to continuously view the television (210), and
the controller (104) stores time information set by the time setting unit (142) and further controls the interface signal processing unit (110) in such a manner that when the viewer is detected by the ultrasonic sensor (150) and the viewing time set by the time setting unit (142) elapses, blue light of the digital image data signal provided from the first digital interface connector is adjusted and the digital image data signal of which the blue light is adjusted is reprocessed and is output to the second digital interface connector,
wherein the television viewing control apparatus (100) further comprises a mounted wireless communication module (160) receiving a remote control signal from a smartphone (220) over a wireless network (20) and providing the remote control signal to the controller (104), and
the controller (104) further controls the interface signal processing unit (110) in such a manner that the digital image data signal output from the first digital interface connector to the second digital interface connector is blocked in response to the remote control signal provided from the mounted wireless communication module (160), or further controls the interface signal processing unit (110) in such a manner that the blue light of the digital image data signal provided from the first digital interface connector is adjusted and the digital image data signal of which the blue light is adjusted is reprocessed and output to the second digital interface connector,
wherein the first digital interface connector and the second digital interface connector are provided as connectors of a High-Definition Multimedia Interface (HDMI) standard,
the interface signal processing unit (110) includes:
an HDMI input unit (111) receiving the digital image data signal from the first digital interface connector;
an HDMI output unit (117) outputting the processed digital image data signal to the second digital interface connector;
a switching unit (112) receiving the digital image data signal of each of the multiple channels from the HDMI input unit (111) and being switched to selectively output the digital image data signals for the respective channels by control of the controller (104); and
a TMDS transmitter (113) receiving the digital image data signals for the respective channels from the switching unit (112) and converting the digital image data signals into TMDS level signals for the respective channels for output to the HDMI output unit (117), and
the controller (104) is configured to,
cause switching-off in such a manner that the digital image data signals for the respective channels provided from the HDMI input unit (111) to the switching unit (112) are blocked from being output to the TMDS transmitter (113); or
cause switching-on in such a manner that the digital image data signals of an R channel and a G channel among the digital image data signals for the respective channels provided from the HDMI input unit (111) to the switching unit (112) are transmitted to the TMDS transmitter (113), simultaneously cause switching-off in such a manner that the digital image data signal of a B channel is blocked and is provided to the controller (104) so that the blue light of the digital image data signal is adjusted, and output the digital image data signal of the B channel of which the blue light is adjusted to the TMDS transmitter (113) in such a manner that the TMDS transmitter (113) reprocesses the digital image data signals of the R channel and the G channel and the digital image data signal of the B channel of which the blue light is adjusted.
