This application is based on and claims priority under 35 U.S.C. § 119(a) of a Korean patent application number 10-2019-0023255, filed on Feb. 27, 2019 in the Korean Intellectual Property Office, the disclosure of which is incorporated by reference herein in its entirety.
The disclosure relates to an electronic device and a controlling method of the electronic device, and more particularly, to an electronic device which is capable of preventing interference between an infrared signal received from a remote control device and an infrared signal output from the electronic device, and a controlling method thereof.
Recently, as the number of electronic devices placed in a home of a user increases, integrated remote control systems for effectively controlling a plurality of electronic devices through one remote control have been developed. Among them, an integrated remote control system using an infrared signal, in particular, can be implemented by a method as discussed below.
First, a remote control device (e.g., a remote control) can output an infrared signal for controlling an external device (e.g., a set top box) according to a user input. An electronic device (e.g., a TV) can receive the infrared signal output from the remote control device, and output an infrared signal for controlling an external device based on the received infrared signal. Then, the external device can receive the infrared signal output from the electronic device, and control the operation of the external device based on the received infrared signal.
However, in this case, an infrared signal is not only output from a remote control device but also from an electronic device, and accordingly, interference may occur between the two infrared signals. Also, in case interference occurs between two infrared signals, misrecognition of signals and breakage of a control operation may occur accordingly.
In particular, according to an operation of a user of pushing one of a plurality of control buttons included in a remote control device for a time period longer than or equal to a predetermined time period, if the remote control device repetitively outputs an infrared signal corresponding to the button, there is a high possibility that interference may occur between the infrared signal repetitively output from the remote control device and an infrared signal repetitively output from an electronic device in accordance thereto.
Accordingly, in an integrated remote control system using an infrared signal, a technology that can prevent interference between an infrared signal output from a remote control device and an infrared signal output from an electronic device is needed.
The disclosure was devised according to the aforementioned need, and the purpose of the disclosure is in preventing interference between an infrared signal received from a remote control device and an infrared signal output from an electronic device.
According to an embodiment of the disclosure for achieving the aforementioned purpose, an electronic device may include an infrared signal receiver, an infrared signal transmitter, a memory that stores computer instruction code, and a processor that executes the computer instruction code.

The processor may identify the type of the first infrared signal based on at least one of the length, the cycle, or the pattern of the first infrared signal.
The processor may, based on the received first infrared signal being an infrared signal of a first type output according to a user input of pushing one of a plurality of control buttons included in the remote control device for a time period shorter than a predetermined time period, identify the output timing of the second infrared signal as a first output timing corresponding to the first type. Meanwhile, the processor may, based on the received first infrared signal being an infrared signal of a second type output according to a user input of pushing one of a plurality of control buttons included in the remote control device for a time period longer than or equal to the predetermined time period, identify the output timing of the second infrared signal as a second output timing corresponding to the second type and different from the first output timing.
The processor may receive a plurality of first infrared signals repetitively output according to a user input of pushing one of a plurality of control buttons included in the remote control device for a time period longer than or equal to the predetermined time period from the remote control device through the infrared signal receiver. Also, the processor may, based on receiving each of the plurality of first infrared signals, control the infrared signal transmitter to repetitively output the identified second infrared signal.
The processor may identify the output timing of the second infrared signal such that each of the output timings of the plurality of second infrared signals repetitively output does not overlap with each of the receiving timings of the plurality of received first infrared signals.
The processor may identify the output timing of the second infrared signal such that each of the output sections of the plurality of second infrared signals has a time interval in a predetermined range with each of the receiving sections of the plurality of first infrared signals.
The processor may, based on receiving the plurality of first infrared signals by a predetermined cycle through the infrared signal receiver, may identify the output timing of the second infrared signal such that the plurality of second infrared signals are output through the infrared signal transmitter by the same cycle as the predetermined cycle by which the plurality of first infrared signals are received.
Meanwhile, the time interval in a predetermined range may be from 15 milliseconds (ms) to 37 milliseconds.
Meanwhile, the electronic device may further include a display, and the processor may blast the second infrared signal to the front surface of the electronic device through a waveguide included in the display.

The step of identifying the output timing of the second infrared signal may further include the step of identifying the type of the first infrared signal based on at least one of the length, the cycle, or the pattern of the first infrared signal.
The step of identifying the output timing of the second infrared signal may further include the steps of, based on the received first infrared signal being an infrared signal of a first type output according to a user input of pushing one of a plurality of control buttons included in the remote control device for a time period shorter than a predetermined time period, identifying the output timing of the second infrared signal as a first output timing corresponding to the first type, and based on the received first infrared signal being an infrared signal of a second type output according to a user input of pushing one of a plurality of control buttons included in the remote control device for a time period longer than or equal to the predetermined time period, identifying the output timing of the second infrared signal as a second output timing corresponding to the second type and different from the first output timing.
The step of receiving a first infrared signal may further include the step of receiving a plurality of first infrared signals repetitively output according to a user input of pushing one of a plurality of control buttons included in the remote control device for a time period longer than or equal to the predetermined time period from the remote control device. Meanwhile, the step of outputting the second infrared signal may further include the step of, based on receiving each of the plurality of first infrared signals, repetitively outputting the identified second infrared signal.

Meanwhile, the time interval in a predetermined range may be from 15 milliseconds (ms) to 37 milliseconds.
Meanwhile, in the step of outputting the second infrared signal, the second infrared signal may be blasted to the front surface of the electronic device through a waveguide included in the display of the electronic device.

Various modifications may be made to the embodiments of the disclosure, and there may be various types of embodiments. Accordingly, specific embodiments will be illustrated in drawings, and the embodiments will be described in detail in the detailed description. However, it should be noted that the various embodiments are not for limiting the scope of the disclosure to a specific embodiment, but they should be interpreted to include all modifications, equivalents and/or alternatives of the embodiments of the disclosure. Meanwhile, with respect to the detailed description of the drawings, similar components may be designated by similar reference numerals.
Also, in case it is determined that in describing the embodiments of the disclosure, detailed explanation of related known functions or components may unnecessarily confuse the gist of the disclosure, the detailed explanation will be omitted.
In addition, the embodiments below may be modified in various different forms, and the scope of the technical idea of the disclosure is not limited to the embodiments below. Rather, these embodiments are provided to make the disclosure more sufficient and complete, and to fully convey the technical idea of the disclosure to those skilled in the art.
Meanwhile, the terms used in the disclosure are just used to explain certain embodiments of the disclosure, and are not intended to limit the scope of protection of the disclosure. Also, singular expressions include plural expressions, unless defined obviously differently in the context.
In the disclosure, terms such as “have,” “may have,” “include” and “may include” should be construed as denoting that there are such characteristics (e.g.: elements such as numerical values, functions, operations and components), and the terms are not intended to exclude the existence of additional characteristics.
Also, in the disclosure, the expressions “A and/or B,” “at least one of A and/or B,” or “one or more of A and/or B” and the like may include all possible combinations of the listed items. For example, “A or B,” “at least one of A and B” or “at least one of A or B” refer to all of the following cases: (1) including at least one A, (2) including at least one B or (3) including at least one A and at least one B.
In addition, the expressions “first,” “second” and the like used in the disclosure may be used to describe various elements regardless of any order and/or degree of importance. Also, such expressions are used only to distinguish one element from another element, and are not intended to limit the elements.
Further, the description in the disclosure that one element (e.g., a first element) is “(operatively or communicatively) coupled with/to” or “connected to” another element (e.g., a second element) should be interpreted to include both the case where the one element is directly coupled to the another element, and the case where the one element is coupled to the another element through still another element (e.g.: a third element).
In contrast, the description that one element (e.g., a first element) is “directly coupled” or “directly connected” to another element (e.g., a second element) can be interpreted to mean that still another element (e.g., a third element) does not exist between the one element and the another element.
Also, the expression “configured to” used in the disclosure may be interchangeably used with other expressions such as “suitable for,” “having the capacity to,” “designed to,” “adapted to,” “made to” and “capable of,” depending on cases. Meanwhile, the term “configured to” does not necessarily mean that a device is “specifically designed to” in terms of hardware.
Instead, under some circumstances, the expression “a device configured to” may mean that the device “is capable of” performing an operation together with another device or component. For example, the phrase “a processor configured to perform A, B and C” may mean a dedicated processor (e.g., an embedded processor) for performing the corresponding operations, or a generic-purpose processor (e.g., a CPU or an application processor) that can perform the corresponding operations by executing one or more software programs stored in a memory device.
Further, in the embodiments, ‘a module’ or ‘a part’ may perform at least one function or operation, and may be implemented as hardware or software, or as a combination of hardware and software. Further, a plurality of ‘modules’ or ‘parts’ may be integrated into at least one module and implemented as at least one processor, excluding ‘a module’ or ‘a part’ that needs to be implemented as specific hardware.

As illustrated in
The remote control device 200 may receive a user input for controlling the electronic device 100 and an external device 300, and output an infrared signal for controlling the electronic device 100 and the external device 300 based on the received user input. In particular, the remote control device 200, according to the disclosure, may receive a user input for controlling the external device 300, and output an infrared signal for controlling the external device 300 based on the received user input. For example, the remote control device 200 may be a remote control, but is not limited thereto, and it may be implemented as a smartphone including an infrared transmission module, etc.
The external device 300 may receive an infrared signal output from the electronic device 100, and control the operation of the external device 300 based on the received infrared signal. For example, the external device 300 may be a set top box, a DVD player, or a console game machine, etc., but the type of the external device 300 is also not limited to a specific type as in the cases of the electronic device 100 and the remote control device 200. Also, the number of the external devices 300 that are the subjects of control by the remote control device 200 is not limited to a specific number, either.
According to an embodiment of the disclosure, the electronic device 100 may receive a first infrared signal from the remote control device 200. Specifically, the electronic device 100 may receive a first infrared signal output from the remote control device 200 according to a user input for controlling the external device 300 connected with the electronic device 100.
To be more specific, based on the remote control device 200 receiving a user input for controlling the external device 300 connected with the electronic device 100, the remote control device 200 may output a first infrared signal for controlling the external device 300 based on the received user input. Then, the electronic device 100 may receive the first infrared signal output from the remote control device 200.
The first infrared signal output from the remote control device 200 may include control information such as the control code of the external device 300, and may have one or more of: a specific length, a specific cycle, or a specific pattern. As described below, the type of the first infrared signal may be identified based on the at least one of the length, the cycle, or the pattern of the first infrared signal.
The length of the first infrared signal may refer to the length of a section where the first infrared signal is received, and the cycle of the first infrared signal may refer to a distance between adjacent first infrared signals in a case the same first infrared signal is repetitively received. Also, the pattern of the first infrared signal may be a characteristic included in the first infrared signal, and it may be, for example, a unique characteristic modulated such that a characteristic according to crossing of a high level and a low level varies according to the type of the first infrared signal.
Based on the first infrared signal being received, the electronic device 100 may identify a second infrared signal corresponding to one of control commands for controlling the operation of the external device 300 based on control information included in the received first infrared signal. Specifically, the electronic device 100 may identify a control command corresponding to the received first infrared signal based on the control code included in the received first infrared signal, and identify a second infrared signal corresponding to the identified control command.
For example, based on the first infrared signal being received, the electronic device 100 may identify a control command of “increase channels” as a control command corresponding to the received first infrared signal based on the control code included in the received first infrared signal, and identify a second infrared signal corresponding to the identified control command.
That is, the electronic device 100 does not output the received first infrared signal as it is, but may identify a second infrared signal corresponding to one of control commands for controlling the operation of the external device 300 based on control information included in the received first infrared signal.
Meanwhile, the electronic device 100 may identify the output timing of the second infrared signal based on the type of the first infrared signal. Then, the electronic device 100 may identify the type of the first infrared signal based on at least one of the length, the cycle, or the pattern of the first infrared signal. Also, at least one of the length, the cycle, or the pattern of the first infrared signal may be identified according to the type of a user input that was input through the remote control device 200. In particular, at least one of the length, the cycle, or the pattern of the first infrared signal may be identified according to whether the length of a user input that was input through the remote control device 200 is longer than or equal to a predetermined time period.
Meanwhile, at least one of the length, the cycle, or the pattern of the first infrared signal may be identified according to the speed of a user input that was input through the remote control device 200, the type of a control command corresponding to the user input, etc. For example, the cycle of the first infrared signal may vary according to a user's speed of pushing one of a plurality of control buttons included in the remote control device 200. Meanwhile, in describing the disclosure below, a case wherein at least one of the length, the cycle, or the pattern of the first infrared signal is identified according to whether the length of a user input that was input through the remote control device 200 is longer than or equal to a predetermined time period will be described in detail.
Meanwhile, in describing the disclosure, the length of a user input refers to the length of a user input of pushing one of a plurality of control buttons included in the remote control device 200. That is, a predetermined time period becomes a standard for distinguishing whether a user input a control command corresponding to a control button once by pushing one of a plurality of control buttons included in the remote control device 200 (i.e., a single key input), or a user continuously input a control command corresponding to a control button (i.e., continuous key inputs). It is obvious that a predetermined time period can vary according to a user's setting.
Specifically, the type of the first infrared signal according to the disclosure may include a first type or a second type. An infrared signal of a first type may refer to an infrared signal which is the received first infrared signal output according to a user input of pushing one of a plurality of control buttons included in the remote control device 200 for a time period shorter than a predetermined time period. Meanwhile, an infrared signal of a second type may refer to an infrared signal of a second type which is the received second infrared signal output according to a user input of pushing one of a plurality of control buttons included in the remote control device 200 for a time period longer than or equal to a predetermined time period.
In other words, based on at least one of the length, the cycle, or the pattern of the received first infrared signal, the electronic device 100 may identify whether the received first infrared signal is an infrared signal of a first type which is the received first infrared signal output according to a user input of pushing one of a plurality of control buttons included in the remote control device 200 for a time period shorter than a predetermined time period, or an infrared signal of a second type output according to a user input of pushing one of a plurality of control buttons included in the remote control device 200 for a time period longer than or equal to a predetermined time period.
Meanwhile, unlike a case where a user input of pushing one of a plurality of control buttons included in the remote control device 200 for a time period shorter than a predetermined time period is received through the remote control device 200, based on a user input of pushing one of a plurality of control buttons included in the remote control device 200 for a time period longer than or equal to a predetermined time period being received through the remote control device 200, the remote control device 200 may repetitively output the first infrared signal. In this case, the electronic device 100 may receive a plurality of first infrared signals repetitively output from the remote control device 200. Then, based on each of the plurality of first infrared signals being received, the electronic device 100 may repetitively output the identified second infrared signal.
Meanwhile, the electronic device 100 may identify the output timing of the second infrared signal based on the aforementioned type of the first infrared signal. Specifically, based on the received first infrared signal being an infrared signal of a first type, the electronic device 100 may identify the output timing of the second infrared signal as a first output timing corresponding to the first type. Also, based on the received first infrared signal being an infrared signal of a second type, the electronic device 100 may identify the output timing of the second infrared signal as a second output timing corresponding to the second type.
To be more specific, based on the received first infrared signal being an infrared signal of a first type output according to a user input of pushing one of a plurality of control buttons included in the remote control device 200 for a time period shorter than a predetermined time period, the electronic device 100 may identify the output timing of the second infrared signal as a first output timing corresponding to the first type.
Also, based on the received first infrared signal being an infrared signal of a second type output according to a user input of pushing one of a plurality of control buttons included in the remote control device 200 for a time period longer than or equal to a predetermined time period, the electronic device 100 may identify the output timing of the second infrared signal as a second output timing corresponding to the second type and different from the first output timing.
Specifically, according to an embodiment of the disclosure, based on the received first infrared signal being an infrared signal of a second type, and the electronic device 100 receiving a plurality of first infrared signals repetitively output from the remote control device 200, the electronic device 100 may identify the output timing of the second infrared signal such that each of the output timings of the plurality of second infrared signals repetitively output does not overlap with each of the receiving timings of the plurality of received first infrared signals.
To be more specific, the electronic device 100 may identify the output timing of the second infrared signal such that each of the output sections of the plurality of second infrared signals has a time interval in a predetermined range with each of the receiving sections of the plurality of first infrared signals. Further, based on the plurality of first infrared signals being received by a predetermined cycle, the electronic device 100 may identify the output timing of the second infrared signal such that the plurality of second infrared signals are output by the same cycle as the predetermined cycle by which the plurality of first infrared signals are received. A more detailed explanation about the output timing of the second infrared signal will be made below with reference to the timing diagrams of
Based on the second infrared signal and the output timing of the second infrared signal being identified as described above, the electronic device 100 may output the identified second infrared signal based on the output timing of the identified second infrared signal. Then, the external device 300 may receive the second infrared signal output from the electronic device 100, and control the operation of the external device 300 based on the received second infrared signal.
According to the aforementioned embodiment of the disclosure, interference between an infrared signal received from the remote control device 200 and an infrared signal output from the electronic device 100 can be prevented. Also, in accordance thereto, misrecognition of signals and breakage of a control operation at an external device can be prevented.
As illustrated in
The infrared signal receiver 110-1 may receive an infrared signal output from the outside of the electronic device 100, and the infrared signal transmitter 110-2 may output an infrared signal to the outside of the electronic device 100.
Specifically, the infrared signal receiver 110-1 may include an infrared phototransistor for receiving infrared rays and a demodulation module for demodulating a modulated infrared signal. Also, the infrared signal transmitter 110-2 may include an infrared rays emitting diode (IRED) for generating an infrared signal and a modulation module for modulating an infrared signal. Meanwhile, in the explanation of the disclosure, description of the infrared signal receiver 110-1 and the infrared signal transmitter 110-2 by specifying them as separate components is not intended to restrict the possibility that the infrared signal receiver 110-1 and the infrared signal transmitter 110-2 can be implemented as one component.
In particular, in the various embodiments according to the disclosure, the infrared signal receiver 110-1 may receive a first infrared signal from the remote control device 200. Specifically, the infrared signal receiver 110-1 may receive a first infrared signal output from the remote control device 200 according to a user input for controlling the external device 300 connected with the electronic device 100.
To be more specific, based on the remote control device 200 receiving a user input for controlling the external device 300 connected with the electronic device 100, the remote control device 200 may output a first infrared signal for controlling the external device 300 based on the received user input. Then, the electronic device 100 may receive the first infrared signal output from the remote control device 200.
Meanwhile, the infrared signal transmitter 110-2 may output a second infrared signal based on the output timing of the second infrared signal. Specifically, the processor 130 may control the infrared signal transmitter 110-2 to output a second infrared signal identified based on the identified output timing.
In the memory 120, computer instruction code, which may include at least one command regarding the electronic device 100, may be stored. Also, in the memory 120, an operating system (O/S) for operating the electronic device 100 may be stored. In addition, in the memory 120, various types of software programs or applications for making the electronic device 100 operate according to the various embodiments of the disclosure may be stored. Further, the memory 120 may include a semiconductor memory, such as, a flash memory or a magnetic storage medium, such as, a hard disk, etc.
Specifically, in the memory 120, various types of software modules for making the electronic device 100 operate according to the various embodiments of the disclosure may be stored, and the processor 130 may control the operation of the electronic device 100 by executing the various types of software modules stored in the memory 120. That is, the memory 120 may be accessed by the processor 130, and one or more of reading/recording/correction/deletion/update, etc. of data by the processor 130 may be performed.
Meanwhile, in the disclosure, the term memory 120 may be used as a meaning including a memory 120, a read only memory (ROM) inside the processor 130, a random access memory (RAM), or a memory card installed on the electronic device 100 (e.g., a micro SD card, a memory stick).
In particular, in the various embodiments according to the disclosure, in the memory 120, information on the output timings of the second infrared signal corresponding to each of types of first infrared signals may be stored. Specifically, in the memory 120, information on the first output timing corresponding to the first infrared signal of the first type and information on the second output timing corresponding to the first infrared signal of the second type, etc. may be stored.

Other than the above, various kinds of necessary information may be stored in the memory 120 within a range for achieving the purpose of the disclosure, and information stored in the memory 120 may be updated as it is received from a server or the external device 300 or input by a user.
The processor 130 may control the overall operations of the electronic device 100. Specifically, the processor 130 may be connected with the components of the electronic device 100 including the infrared signal receiver 110-1, the infrared signal transmitter 110-2, and the memory 120 as described above, and may control the overall operations of the electronic device 100 by executing computer instruction code, which may include at least one command, stored in the memory 120 as described above. Also, the memory 130 may perform a process of controlling the electronic device 100 according to the disclosure based on various kinds of information stored in the memory 120.
The processor 130 may be implemented in various ways. For example, the processor 130 may be implemented as at least one of an application specific integrated circuit (ASIC), an embedded processor, a microprocessor, a hardware control logic, a hardware finite state machine (FSM), or a digital signal processor (DSP). Meanwhile, in the disclosure, the term processor 130 may be used as a meaning including one or more of a central processing unit (CPU), a graphic processing unit (GPU), and a main processing unit (MPU), etc.

Hereinafter, a controlling process of the processor 130 according to the disclosure will be described in detail.
According to an embodiment of the disclosure, the processor 130 may receive a first infrared signal output from the remote control device 200 according to a user input for controlling the external device 300 connected with the electronic device 100 through the infrared signal receiver 110-1.
To be more specific, based on the remote control device 200 receiving a user input for controlling the external device 300 connected with the electronic device 100, the remote control device 200 may output a first infrared signal for controlling the external device 300 based on the received user input. Then, the processor 130 may receive the first infrared signal output from the remote control device 200 through the infrared signal receiver 110-1.
The first infrared signal output from the remote control device 200 may include control information such as the control code of the external device 300, and may have one or more of a specific length, a specific cycle, or a specific pattern.

Here, the length of the first infrared signal may refer to the length of a section wherein the first infrared signal is received, and the cycle of the first infrared signal may refer to a distance between adjacent first infrared signals in case the same first infrared signal is repetitively received. Also, the pattern of the first infrared signal may be a characteristic included in the first infrared signal, and it may be, for example, a unique characteristic modulated such that a characteristic according to crossing of a high level and a low level varies according to the type of the first infrared signal.
Based on the first infrared signal being received, the processor 130 may identify a second infrared signal corresponding to one of control commands for controlling the operation of the external device 300 based on control information included in the received first infrared signal. Specifically, the processor 130 may identify a control command corresponding to the received first infrared signal based on the control code included in the received first infrared signal, and identify a second infrared signal corresponding to the identified control command.
For example, based on the first infrared signal being received, the processor 130 may identify a control command “increase channels” as a control command corresponding to the received first infrared signal based on the control code included in the received first infrared signal, and identify a second infrared signal corresponding to the identified control command.
That is, the processor 130 does not control the infrared signal transmitter 110-2 to output the received first infrared signal as it is, but may identify a second infrared signal corresponding to one of control commands for controlling the operation of the external device 300 based on control information included in the received first infrared signal and control the infrared signal transmitter 110-2 to output the second infrared signal.
Meanwhile, the processor 130 may identify the output timing of the second infrared signal based on the type of the first infrared signal. Then, the processor 130 may identify the type of the first infrared signal based on at least one of the length, the cycle, or the pattern of the first infrared signal. Also, at least one of the length, the cycle, or the pattern of the first infrared signal may be identified according to the type of a user input that was input through the remote control device 200. In particular, at least one of the length, the cycle, or the pattern of the first infrared signal may be identified according to whether the length of a user input that was input through the remote control device 200 is longer than or equal to a predetermined time period.
Meanwhile, at least one of the length, the cycle, or the pattern of the first infrared signal may be identified according to the speed of a user input that was input through the remote control device 200, the type of a control command corresponding to the user input, etc. For example, the cycle of the first infrared signal may vary according to a user's speed of pushing one of a plurality of control buttons included in the remote control device 200. Meanwhile, in describing the disclosure below, a case where at least one of the length, the cycle, or the pattern of the first infrared signal is identified according to whether the length of a user input that was input through the remote control device 200 is longer than or equal to a predetermined time period will be described in detail.
Meanwhile, in describing the disclosure, the length of a user input may refer to the length of a user input of pushing one of a plurality of control buttons included in the remote control device 200. That is, a predetermined time period may become a standard for distinguishing whether a user input a control command corresponding to a control button once by pushing one of a plurality of control buttons included in the remote control device 200 (i.e., a single key input), or a user continuously input a control command corresponding to a control button (i.e., continuous key inputs). It is obvious that a predetermined time period can vary according to a user's setting.
Specifically, the type of the first infrared signal according to the disclosure may include a first type and a second type. An infrared signal of a first type may refer to an infrared signal which is the received first infrared signal output according to a user input of pushing one of a plurality of control buttons included in the remote control device 200 for a time period shorter than a predetermined time period. Meanwhile, an infrared signal of a second type may refer to an infrared signal of a second type which is the received second infrared signal output according to a user input of pushing one of a plurality of control buttons included in the remote control device 200 for a time period longer than or equal to a predetermined time period.
In other words, based on at least one of the length, the cycle, or the pattern of the received first infrared signal, the processor 130 may identify whether the received first infrared signal is an infrared signal of a first type which is the received first infrared signal output according to a user input of pushing one of a plurality of control buttons included in the remote control device 200 for a time period shorter than a predetermined time period, or an infrared signal of a second type output according to a user input of pushing one of a plurality of control buttons included in the remote control device 200 for a time period longer than or equal to a predetermined time period.
Meanwhile, unlike a case where a user input of pushing one of a plurality of control buttons included in the remote control device 200 for a time period shorter than a predetermined time period is received through the remote control device 200, based on a user input of pushing one of a plurality of control buttons included in the remote control device 200 for a time period longer than or equal to a predetermined time period being received through the remote control device 200, the remote control device 200 may repetitively output the first infrared signal. In this case, the processor 130 may receive a plurality of first infrared signals repetitively output from the remote control device 200 through the infrared signal receiver 110-1. Then, based on each of the plurality of first infrared signals being received, the processor 130 may repetitively output the identified second infrared signal through the infrared signal transmitter 110-2.
Meanwhile, the processor 130 may identify the output timing of the second infrared signal based on the aforementioned type of the first infrared signal. Specifically, based on the received first infrared signal being an infrared signal of a first type, the processor 130 may identify the output timing of the second infrared signal as a first output timing corresponding to the first type. Also, based on the received first infrared signal being an infrared signal of a second type, the processor 130 may identify the output timing of the second infrared signal as a second output timing corresponding to the second type.
To be more specific, based on the received first infrared signal being an infrared signal of a first type output according to a user input of pushing one of a plurality of control buttons included in the remote control device 200 for a time period shorter than a predetermined time period, the processor 130 may identify the output timing of the second infrared signal as a first output timing corresponding to the first type.
Also, based on the received first infrared signal being an infrared signal of a second type output according to a user input of pushing one of a plurality of control buttons included in the remote control device 200 for a time period longer than or equal to a predetermined time period, the processor 130 may identify the output timing of the second infrared signal as a second output timing corresponding to the second type and different from the first output timing.
Specifically, according to an embodiment of the disclosure, based on the received first infrared signal being an infrared signal of a second type, and the processor 130 receiving a plurality of first infrared signals repetitively output from the remote control device 200 through the infrared signal receiver 110-1, the processor 130 may identify the output timing of the second infrared signal such that each of the output timings of the plurality of second infrared signals repetitively output does not overlap with each of the receiving timings of the plurality of received first infrared signals.
To be more specific, the processor 130 may identify the output timing of the second infrared signal such that each of the output sections of the plurality of second infrared signals has a time interval in a predetermined range with each of the receiving sections of the plurality of first infrared signals. Further, based on the plurality of first infrared signals being received by a predetermined cycle, the processor 130 may identify the output timing of the second infrared signal such that the plurality of second infrared signals are output by the same cycle as the predetermined cycle by which the plurality of first infrared signals are received.
As described above, the output timings of the plurality of second infrared signals may be identified by the relation with the receiving timings of the plurality of received first infrared signals. Information on the receiving timings of the plurality of first infrared signals may be stored in the memory 120 in advance, or it may be received from an external device or a server through a communication interface as will be described below.
More detailed explanation about the output timing of the second infrared signal will be made below with reference to the timing diagrams of
Based on the second infrared signal and the output timing of the second infrared signal being identified as described above, the processor 130 may control the infrared signal transmitter 110-2 to output the second infrared signal identified based on the output timing of the identified second infrared signal. Then, the external device 300 may receive the second infrared signal output from the infrared signal transmitter, and control the operation of the external device 300 based on the received second infrared signal.
