Description

CROSS-REFERENCE TO RELATED APPLICATION(S)

This application claims the benefit under 35 U.S.C. § 119(a) of a Korean patent application filed on Nov. 4, 2013 in the Korean Intellectual Property Office and assigned Serial number 10-2013-0133023, the entire disclosure of which is hereby incorporated by reference.

TECHNICAL FIELD

The present disclosure relates to an Infrared (IR) communication method and an electronic device thereof.

BACKGROUND

Infrared (IR) communication technology is widely used for a remote controller for controlling home appliances, such as a TV, a stereo, or an air conditioner, in a wireless manner. For example, in order to facilitate IR communication between a remote controller and a TV, an IR Transmission (Tx) module is mounted in the front portion of a TV remote controller and an IR Reception (Rx) module is mounted in a TV box.

With the development of the IR communication technology, a smart phone may be used for a remote controller and may transmit data to computer peripherals, such as printer, using IR communication. The IR communication technology has developed into Infrared Data Association (IrDA) technology. The IrDA technology is one of short-range wireless communication technologies of directionally transmitting information in a wireless manner using infrared.

According to the IrDA-1.1 standard, the maximum data size that may be transmitted is 2048 bytes and the maximum transmission rate is 4 Mbps. For bidirectional communication using the IrDA technology, transmitter-side and receiver-side electronic devices each need to include IR transmission/reception modules and a software application program is required in order to perform synchronization for communication.

FIGS. 1A and 1B are diagrams illustrating bidirectional IR communication states between electronic devices according to the related art.

Referring to FIGS. 1A and 1B, a first terminal and a second terminal each have IR Tx/Rx modules (not illustrated) and perform a pairing process in a state in which the terminals (e.g., the IR TX module and the IR RX module of the respective terminals) face each other for IR communication to perform IR communication.

As example, a terminal may correspond to various types of electronic devices, such as smart phone or tablet PC.

FIG. 2 illustrates a bidirectional IR communication process between electronic devices according to the related art.

Referring to FIG. 2, a first terminal 201 and a second terminal 203 are in IR communication.

At operation 205, the first terminal 201 generates a first request signal (Request #1) inquiring about identification of the second terminal 203 and transmits the first request signal using infrared.

At operation 207, the second terminal 203 generates a first response signal (Response #1) responding about identification of the second terminal 203. The response to the first request signal (Response #1) includes identification information of the second terminal 203. The second terminal 203 transmits the first response signal using infrared.

Thereafter, at operations 209, 211, and 213, the first terminal 201 and the second terminal 203 undergo a pairing process. For example, during the pairing process, at operation 209, a request signal (Request #n) is transmitted. At operation 211, a response signal (Response #n) is transmitted. The request signal and the response signal are transmitted and received n times through a plurality of steps and share various information through IR communication. At operation 213, the second terminal 203 pairs with the first terminal 201.

The above information is presented as background information only to assist with an understanding of the present disclosure. No determination has been made, and no assertion is made, as to whether any of the above might be applicable as prior art with regard to the present disclosure.

The operational principle of various embodiments of the present disclosure will be described herein below with reference to the accompanying drawings. In the following description, detailed descriptions of well-known functions or configurations will be omitted because such detailed descriptions may unnecessarily obscure the subject matters of the present disclosure. Furthermore, terms to be described below have been defined by considering functions in various embodiments of the present disclosure, and may be defined differently depending on a user or operator's intention or practice. Therefore, the terms used herein should be understood based on the descriptions made herein.

An IR communication method in an electronic device and the electronic device according to various embodiments of the present disclosure will be described in detail below. The electronic device according to various embodiments of the present disclosure may be configured by including the components illustrated in FIG. 5 and the communication module 230 of the electronic device may further include an IR module.

FIG. 6 is a diagram illustrating a detailed configuration of an electronic device according to an embodiment of the present disclosure.

Referring to FIG. 6, an electronic device, such as a smart phone a tablet PC, or the like may include a IR module 500, an analog processor 600, a digital processor 700, and an application program 800 which is in a freeze state for power saving in a sleep mode.

The freeze state refers to an idle state which an application program enters for power saving, whereas an unfreeze state refers to an activity state in which the sleep mode is released and an application program is activated.

The IR module 500 may include an IR transmitter (TX) 501 and an IR receiver (RX) 502. The IR module 500 may include an IR LED for an IR transmitter 501 for transmitting infrared and a Photo Detector (PD) as an IR receiver 502 for receiving infrared. The IR LED and the PD may be manufactured as one package. Furthermore, the package may include two or more PDs arranged in parallel in order to improve infrared reception sensitivity.

The analog processor 600 may include a TRansistor (TR) 601, an AMPlifier (AMP) 602, a filter 603, and a signal compensator 604. The TR 601 may be a switching element for converting an electrical signal which is input to the IR LED into a rectangular pulse signal, and may be included in the IR module 500 along with the IR LED.

The AMP 602 may be implemented using a preamplifier for amplifying a low-level electrical signal output from the PD to have a predetermined or more level of voltage. The electrical signal output from the PD may be amplified to have a predetermined or more level of voltage by passing through the AMP 602. The filter 603 may be configured to remove the noise component of the electrical signal amplified by the AMP 602 to have the predetermined or more level of voltage and may be implemented using a band-pass filter.

The signal compensator 604 may compensate for the distortion component of the electrical signal that has passed through the filter 603. For example, the signal compensator 604 compensates for undesired amplitude distortion and phase distortion when the electrical signal passes through the AMP and the filter.

The analog processor 600 may be configured by a driver IC. The filter 603 for removing noise components and the signal compensator 604 for compensating for the distortion components may be omitted in the analog processor 600.

The IR module 500 and the analog processor 600 maintain an operable state in which normal power is continuously supplied thereto even when the electronic device is in a sleep mode.

The digital processor 700 converts the analog signals into digital data and determines whether the digital data is valid data. When the digital data is valid data, the digital processor 700 activates the application program 800 which had been in the freeze state so as to be in the unfreeze state.

The digital processor 700 may ignore (e.g., not respond to) the digital data when the digital data is determined not to be valid data and may maintain the application program in the freeze state. The digital processor 700 may be implemented using a Field Programmable Gate Array (FPGA) IC. The digital processor 700 maintains a standby state in which low power is supplied thereto when the electronic device is in the sleep mode. When the voltage level of the analog signal is equal to or larger than a predetermined level, the digital processor 700 may performs witching to the operable state from the standby state.

The digital processor 700 may include a digital converter 701, a data processor 702, and a controller 703.

The digital converter 701 may convert an analog signal output from the analog processor 600 into digital data. The digital converter 701 may be implemented using an Analog-to-Digital Converter (ADC) and may convert the analog signal into the digital data by using a frequency clock signal (e.g., 10 Hz) for the sleep mode.

The data processor 702 may determine whether the digital data is valid data.

The controller 703 may generate an interrupt signal for activating the application program 800 which had been in the freeze state so as to be in the unfreeze state if the digital data is determined to be valid data. For example, the controller 703 may generate the interrupt signal for activating the application program 800 in response to the digital data being determined to be valid. The controller 703 generates the interrupt signal to activate the application program 800 and, thereafter, transmits the digital data to the application program. The interrupt signal and the digital data transmitted from the controller 703 are sequentially transmitted to the application program 800 at predetermined time intervals or are transmitted in one continuous data stream.

According to various embodiments of the present disclosure, the application program 800 may immediately perform IR communication with a party electronic device that had transmitted infrared in response to the digital data transmitted from the controller 703 after being activated by the interrupt signal or may selectively perform IR communication depending on whether a user accepts the IR communication. According to various embodiments of the present disclosure, the application program 800 may be an IR pairing program for performing bi-directional IR communication with the party electronic device. The data processor 702 and the controller 703 may be integrated into one component or may be included in the processor 210 of the electronic device illustrated in FIG. 4.

FIGS. 7A and 7B are display screens of an electronic device according to an embodiment of the present disclosure.

FIG. 8 is a diagram illustrating an IR communication process between electronic devices according to an embodiment of the present disclosure.

According to various embodiments of the present disclosure, a terminal may be an electronic device such as a smart phone, a tablet PC, or the like.

Referring to FIG. 7A, a first terminal (Terminal 1) 710 and a second terminal (Terminal 2) 730 each have an IR module (not illustrated) and perform a pairing process in a state in which the first terminal 710 and the second terminal 730 face each other for IR communication to perform IR communication.

For example, the first terminal 710 may be in an operable state, and the second terminal 730 may be in a sleep mode. The first terminal 710 may display an IR-pairing button on a screen according to a user's request and, when the user touches the IR-pairing button (e.g., in response to the user touching the IR-pairing button), the first terminal 710 generates a request signal Request #1 for immediate performance of the IR pairing and transmits the request signal to the second terminal 730 using infrared. The IR module 500 of the second terminal 730 converts the infrared of the request signal into an electrical signal and outputs the electrical signal. According to various embodiments of the present disclosure, the analog processor 600 of the second terminal 730 amplifies, filters, and compensates the electrical signal, and outputs an analog signal having no distortion and noise (or reduced distortion and noise), the level of which is equal to or larger than a predetermined level. According to various embodiments of the present disclosure, the IR module 500 and the analog processor maintain the operable state in which normal power is continuously supplied thereto even when the second terminal 730 is in the sleep mode.

According to various embodiments of the present disclosure, the digital processor 700 of the second terminal 730 performs a data conversion operation of converting the analog signal into digital data and determines whether the digital data is valid. If the digital data is valid as a result of the determination (e.g., in response to the digital valid being determined to be valid), then the digital processor 700 of the second terminal 730 generates an interrupt signal for activating an application program 800 which is in the freeze state of the sleep mode to be in an unfreeze state. The digital processor 700 of the second terminal 730 transmits all or a portion of digital data in a state in which the application program 800 is activated and the application program 800 identifies the digital data and immediately performs the IR pairing operation with the first terminal (Terminal 1) 710 which has transmitted the request signal (request #1) of the infrared.

For example, a guide message and a touch button for receiving an accept with respect to the IR pairing operation with the first terminal 710 from the user may be displayed on the second terminal (Terminal 2) 730 as illustrated in FIG. 7B. According to whether the user accepts the IR pairing operation (e.g., indicates acceptance in relation to the guide message), the IR pairing may be selectively performed. In contrast, the digital processor 700 of the second terminal 730 ignores the digital data when the digital data is determined not to be valid data (e.g., in response to the digital data being determined not to be valid data) and maintains the freeze state of the application program.

FIG. 9 is a diagram illustrating information for a transmitter-side electronic device according to an embodiment of the present disclosure.

Referring to FIG. 9, the digital data may include the identification information and performance information of the first terminal 710 which has transmitted the request signal (request #1). For example, the terminal information included in the digital data may include a device type, a manufacturer, version, a device identifier (ID), an error detection/correction, backhaul information of the terminal, and/or the like as illustrated in FIG. 9.

The device type, the manufacturer, the version, and the device ID may correspond to the identification information of the terminal and the error detection/correction and backhaul information may correspond to the performance information of the terminal. The terminal information may include various types of information additionally and unnecessary information thereof may be omitted. The digital processor 700 of the second terminal 730 identifies one or more of the device type, the manufacturer, the version, and the device ID of the first terminal and, if the first terminal 710 is a specific terminal having enough performance to perform IR pairing, then the second terminal 730 determines that the digital data is valid or, if the first terminal 710 is not the specific terminal, then the second terminal 730 determines that the digital data is not valid.

According to various embodiments of the present disclosure, the application program 800 identifies not only the device type, manufacturer, version, device ID of the first terminal but also error detection/correction and backhaul information and immediately performs IR pairing with the second terminal 730 or selectively performs IR pairing depending to a user's accept as illustrated in FIG. 7B. On the first terminal 710, a message notifying accept waiting state may be displayed for a predetermined time.

As illustrated in FIG. 8, a first terminal 810 and a second terminal 830 communicate with each other.

At operation 840, the first terminal 810 generates a request signal for performing IR pairing. The first terminal 810 transmits the request signal for IR pairing to the second terminal 830. The first terminal 810 may generate the request signal in response to a user input to the first terminal 810 requesting IR pairing.

At operation 850, the second terminal 820 performs data conversion. For example, in response to receiving the request signal from the first terminal 810, the second terminal 830 performs data conversion. As an example, the IR module 500 of the second terminal 830 converts the infrared of the request signal into an electrical signal and outputs the electrical signal. The second terminal 830 may convert the analog signal into digital data.

At operation 860, the second terminal 830 determines a validity of the data.

At operation 870, the second terminal 830 may wake up. The application on the second terminal 830 may activate and/or wakeup. For example, if the digital data is valid as a result of the determination (e.g., in response to the digital valid being determined to be valid), then the digital processor 700 of the second terminal 830 generates an interrupt signal for activating an application program 800 which is in the freeze state of the sleep mode to be in an unfreeze state. The digital processor 700 of the second terminal 830 transmits all or a portion of digital data in a state in which the application program 800 is activated and the application program 800 identifies the digital data and immediately performs the IR pairing operation with the first terminal (Terminal 1) 810 which has transmitted the request signal (request #1) of the infrared.

At operation 880, the second terminal 830 performs the IR pairing operation with the first terminal 810.

FIG. 10 is a diagram illustrating an operation flowchart for an IR communication method of an electronic device according to an embodiment of the present disclosure.

FIGS. 11A and 11B are display screens of an electronic device according to an embodiment of the present disclosure.

As described above with reference to FIG. 6, a terminal may be an electronic device, such as a smart phone or a tablet PC, which includes the IR module 500, the analog processor 600, the digital processor 700 and the application program 800.

The IR module 500 and the analog processor 600 of the terminal maintain an operable state in which normal power is continuously supplied even when the terminal is in a sleep mode for power saving.

At operation S10, the terminal determines whether an infrared signal is received.

If the terminal determines that an infrared signal is not received at operation S10, then the terminal may return to operation S10 at which the terminal continues to poll for reception (e.g., detection) of an infrared signal.

If infrared is received (e.g., through the photo detector 502 of the IR module 500) at operation S10, then the terminal proceeds to operation S11 at which the photo detector 502 converts the infrared into an electrical signal and outputs the same. The AMP 602 of the analog processor 600 amplifies the electrical signal to have a predetermined or more level of voltage. The filter 603 of the analog processor 600 removes noise components from the amplified electrical signal. The signal compensator 604 of the analog processor 600 performs an analog signal processing operation of compensating for distortion of the electrical signal from which the noise components are removed.

The digital processor 700 maintains a standby state in which low power is continuously supplied when the terminal is in the sleep mode for power saving. If the voltage level of the analog signal is equal to or larger than a predetermined level (e.g., in response to the voltage level of the analog signal being determined to be equal to or larger than a predetermined level), then the digital processor 700 performs switching from the standby mode to the active mode to be in an operable state in which normal power is continuously supplied. The digital converter 701 of the digital processor 700 converts the analog signal into digital data. For example, the digital converter 701 may be implemented using an ADC.

At operation S12, the digital converter 701 performs a digital processing operation of converting the analog signal into the digital data by using a frequency clock signal (e.g., 10 Hz) for the sleep mode.

At operation S13, the terminal determines whether the digital data is valid data. For example, the data processor 701 of the digital processor 700 determines whether the digital data is valid data. As described above with reference to FIG. 9, the digital data may include the identification information and performance information of a counterpart terminal that has requested IR communication. For example, the digital data may include the device type, manufacturer, version, device ID, error detection/correction and backhaul information of the terminal as illustrated as terminal information.

According to various embodiments of the present disclosure, the data processor 702 identifies one or more of the device type, manufacturer, version, and device ID of the counterpart terminal. When the counterpart terminal is a specific terminal having enough performance to perform IR pairing, determines that the digital data is valid or otherwise, determines that the digital data is not valid.

If the terminal determines that the digital data is not valid at operation S13, then the terminal may return to operation S10 at which the terminal polls for reception of an infrared signal.

In contrast, if the terminal determines that the digital data is valid at operation S13, and the terminal may proceed to operation S14 at which the application program state is identified. For example, the controller 703 of the digital processor 700 identifies the application program state. If the application program 800 is not in the freeze state, then the terminal does not generate the interrupt signal to wake up the application program 800.

At operation S15, the terminal determines whether the application program state is in a freeze state. For example, at operation S15, the controller 703 of the digital processor 700 identifies whether the application program 800 for IR communication is in the freeze state for power saving.

If the terminal determines that the application program state is in a freeze state at operation S15 (e.g., in response to determining that the application state is in a freeze state), then the terminal may proceed to operation S15 at which the terminal generates an interrupt signal for activation (e.g., of the application program 800). If the controller 703 of the digital processor 700 determines that the application program 800 is in the freeze state at operation S15, then at operation S16, the controller 703 generates the interrupt signal for activating the application program 800 to be in the unfreeze state. If the application program 800 is determined not to be in the freeze state, then the interrupt signal is not generated.

Thereafter, at operation S17, the terminal transmits digital data to the application program 800 that is in an active state. For example, at operation S17, controller 703 transmits the digital data to the application program that is in the active state. The interrupt signal and the digital data transmitted from the controller 703 are sequentially transmitted to the application program 800 at predetermined time intervals or are transmitted in one continuous data stream.

At operation S18, the application program 800 may immediately perform IR communication with the counterpart terminal that has transmitted infrared in response to the digital data transmitted from the controller 703 or selectively perform IR communication depending on the user's accept. For example, in response to transmission of the digital data to the application program that is in an active state, the terminal may perform IR communication with the counterpart terminal.

Thereafter, at operation S19, the application program 800 performs an operation requested by the user.

As illustrated in FIGS. 11A and 11B, the terminals (e.g., first terminal 1110 (Terminal 1) and second terminal 1130 (Terminal 2)), such as smart phone or tablet PC, may perform bidirectional IR communication between each other and IR communication with a terminal which is in a sleep mode may be performed rapidly and effectively.

According to the various embodiments of the present disclosure, bidirectional IR communication between electronic devices, such as smart phone or tablet PC may be performed immediately by a user's simple manipulation, thereby improving user convenience. In addition, when a transmitter electronic device transmits a request signal using infrared, a receiver electronic device which is in a sleep state performs switching to an activity state in response to the request signal and immediately perform IR communication with the transmitter electronic device, thereby effectively and rapidly performing bidirectional IR communication with the electronic device which is in the sleep mode.

The methods according to the various embodiments described in the claims or specification of the present disclosure may be implemented by hardware, software, or a combination thereof. If the methods are implemented by software, a non-transitory computer-readable storage medium may be provided to store one or more programs (software modules). The one or more programs stored in the non-transitory computer-readable storage medium may be configured for execution by one or more processors in an electronic device.

The one or more programs may include instructions for causing the electronic device to execute the methods according to the various embodiments of the present disclosure described in the claims and/or specification of the present disclosure. These programs (software modules or software) may be stored in RAMs, nonvolatile memories including flash memories, ROMs, EEPROMs, magnetic disc storage devices, CD-ROMs, DVDs, other types of optical storage devices, or magnetic cassettes.

In addition, the programs may be stored in a memory configured by a combination of some or all of such storage devices. In addition, each of the memories may be provided in plurality. In addition, the program may be stored in an attachable storage device that can access the electronic device via a communication network such as the Internet, an Intranet, a Local Area Network (LAN), a Wide LAN (WLAN), and a Storage Area Network (SAN), or a communication network configured in combination of them. The storage device may access the electronic device via an external port. In addition, a separate storage device on a communication network may access a mobile electronic device.

While the present disclosure has been shown and described with reference to various embodiments thereof, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the present disclosure as defined by the appended claims and their equivalents.
