Description
- The present invention relates to a device for controlling television (TV) viewing, and more specifically, to a device for controlling a TV viewing device capable of connecting a TV to a smart phone via a communication network, transmitting an image captured by a built-in camera to the smart phone, displaying an image signal of the smart phone through the TV to implement a TV bidirectional video call between the built-in camera, the TV, and the smart phone, and control TV viewing in linkage with the smart phone via a wireless communication network such that a bidirectional video call using a TV is performable without a separate communication device such as a smart phone.
- Along with popularization and high-speed of the Internet, internet protocol (IP) televisions (TVs) have been manufactured in large size and high-definition, and such a trend of TVs being large in size and being high-definition is expected to be intensified. In addition, with the popularization of smart TVs, TVs are expected to have higher utilization.
- However, despite such a change, TVs have remained at a level of being utilized as a one-way information transmission device.
- In addition, even when TVs are already connected to the Internet, a communication with external devices is achieved using separate communication devices such as smart phones. That is, mostly, even with TVs of high definition, large size, and smart features, a video call is made through a smart phone, which has a relatively small screen, or a voice call is simply made.
- This is a limitation in smooth communication of users with a low level of understanding of information transmission, such as the elderly and children. In addition, in an emergency where it is difficult to use a smart phone, there is no appropriate method of communication with external devices.
- In addition, with the proliferation of single-person households in recent years, the number of generations living with companion animals is increasing, which frequently causes side effects, such as separation anxiety of companion animals and disturbance of a house due to the companion animals remaining alone when the owner leaves the house or goes to work. However, currently, methods of immediately identifying the situation of companion animals by the owner of the companion animals and properly controlling the situation stay at a level of using IP-Cameras, which are devices using a one-way video transmission method, because of the absence of an appropriate method, other than the owner's voice, of controlling companion animals that have separation anxiety and other problems.
- In addition, when there are only children in the house, parents have no choice but to give the children the parents' smart phones for communication with the children, which causes overuse of smart phones because the children use the smart phones freely outside of parental control.
- There is a need to develop a technology for obviating for the above described side effects using high-definition and large sized TVs without depending on smart phones.
- In addition, in order to properly protect eyesight from excessive use of TV, there is a need to appropriately adjust the brightness and color of the TV screen according to the surrounding lighting conditions. However, adjusting functions embedded in TVs need to be manually adjusted by users frequently and most users are unaware of the adjusting functions, and currently there is no method of automatically controlling the functions. Due to the above described side effects and increasing dependence on smart phones, the number of people who wear glasses at an early age is increasing every year.
- Accordingly, there is a need to develop apparatuses for automatically protecting eyesight of viewers by automatically adjusting the brightness and color of a TV screen according to changes in external lighting.
- Modern people spend a considerable amount of time watching TV. It is recommended to watch TV at an appropriate distance and for an appropriate time to protect eyesight and maintain health.
- However, in practice, children and toddlers have difficulty in observing the TV viewing distance and have negative effects due to excessive TV viewing.
- Despite the drawbacks, parents do not have enough methods to control TV viewing when the children continue to watch TV or do not observe the TV viewing distance, so excessive verbal abuse or corporal punishment occurs, which may cause family feuds sometimes that lead to bad relationships between the parents and the children.
- In addition, as TVs have recently become larger and improved, a TV is combined with a game console as an attempt to play various games through a TV screen, and various age groups from infants to teenagers seek pleasure through TVs.
- As such, TV viewing occupies a large part of the family feuds, and currently, there is no solution for control of TV viewing.
- The present invention is directed to providing a device for controlling television (TV) viewing that is capable of connecting a TV to a smart phone via a communication network, transmitting an image captured by an embedded camera to the smart phone, displaying an image signal of the smart phone through the TV to implement TV bidirectional video calling between the embedded camera, the TV, and the smart phone, and control TV viewing in linkage with the smart phone via a wireless communication network such that bidirectional video calling using a TV is performable without a separate communication device, such as a smart phone.
- The present invention is directed to providing a method of protecting eyesight of viewers by automatically adjusting the brightness and color of a TV according to a change in external lighting.
- One aspect of the present invention provides a device for controlling television (TV) viewing capable of bi-directional video calling including:

- wherein 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, and transmit the generated response signal to the smart phone.
- The device may further include a multi-sensor module electrically connected to the controller, and the multi-sensor module may include:
- 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.
- The controller may be configured to, in response to receiving a response signal to a 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 a video call, 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 digital image source or the wireless communication module and output the image data signal and the voice data signal to the TV to perform a bi-directional video call between the built-in camera, the TV, and the smart phone.
- As is apparent from the above, the present invention connects a television (TV) to the smart phone through a communication network to implement a TV interactive content control service so that video calls, security functions, and TV viewing control functions can be performed.
- The present invention can implement various multimedia services by expanding a high-definition multimedia interface (HDMI) channel to two channels.
- The present invention can support a video call between a TV and a smart phone with a simple button operation in case of an emergency situation of the elderly, infants, and children who have difficulty in using a separate communication device.
