In the following description, well-known functions or constructions are not described in detail since they would obscure the invention in unnecessary detail.

Throughout the specification, when an element is referred to as "comprising ", it means that it can include other elements as well, without excluding other elements unless specifically stated otherwise. Also, the terms " part, "" unit," " unit, "and " module" refer to units that process at least one function or operation, May be implemented as a combination.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a diagram illustrating an exemplary system environment for identifying a designated electronic device 200 in accordance with the present invention. The system environment includes the identification device 100 and one or more electronic devices 200 and may further include a remote server 400, a download server 300, and a communication network 500.

This system environment allows the identification device 100 to identify the electronic device 200 to set a set of control codes that can be used in the electronic device 200 and furthermore the identification device 100 can communicate with the remote server 400 Or receive a program or the like from the download server 300 that can be used in the identification device 100. [

As for each device in this system environment, the electronic device 200 is a device installed or provided in an office or a home. The electronic device 200 may be, for example, a TV, a DVD player, a Blu-ray player, an audio cassette, an audio deck, an air conditioner,

The electronic device 200 includes an infrared light receiving unit capable of receiving a wireless infrared signal, and the operation of the electronic device 200 can be controlled according to a wireless remote control signal such as a received infrared signal. As described above, the electronic device 200 receives control signals through a simple remote control interface and can be controlled according to the functions and characteristics of the electronic devices 200.

Here, the electronic device 200 can be classified into two types. The first type is an electronic device 200 in which the electronic device 200 internally reproduces an audio source such as audio content and outputs an audio signal. This first type of electronic device 200 may be, for example, a TV, a DVD player, a Blu-ray player, an audio cassette, an audio deck, and the like. This first type of electronic device 200 includes, for example, a speaker or outputs an audio signal to be provided to the speaker. Accordingly, the first electronic device 200 is configured to output audio or stop output in accordance with a control signal (remote control signal) such as a mute button or the like of the remote control.

The second type is an electronic device 200 in which the electronic device 200 does not reproduce audio reproduced internally, such as audio content, such as audio content. This second type of electronic device 200 is configured to output a signal sound so that the user can confirm the input or reception of the remote control signal.

The control code set includes a remote control code set of the values of the remote control codes to be output from the specific electronic device 200, and the remote control code further includes an output format upon outputting a control signal such as a remote control signal using an infrared ray or the like . Such an output format may be, for example, a time or axis format of a leader code on output (designation of the period and order of '1' and '0' for the output signal, etc.) And the duration and format of the trailer code (designation of the duration and order of '1' and '0' for the output signal).

The control code set may be identified for each electronic device 200 or each manufacturer of the electronic device 200. For example, the control code set may include a manufacturer ID assigned to a manufacturer, an ID of the electronic device 200, Lt; / RTI >

Accordingly, the remote server 400 can transmit the specific control code set to the requesting identification device 100 using the ID included in the request, according to the request received from the identification device 100. [

The communication network 500 is a network that enables data to be transmitted and received between the remote server 400 and / or the download server 300 and the identification device 100. The communication network 500 may be a wired communication network and / or a wireless communication network. For example, the communication network 500 may include a mobile communication network such as CDMA or GSM, a wired communication network such as Wi-Fi, Bluetooth or ZigBee, . ≪ / RTI >

The communication network 500 may constitute an Internet network, for example.

The identification device 100 identifies the electronic device 200 by recognizing the response of the electronic device 200 by sound in response to the transmission of a control signal such as an infrared remote control signal and further identifies the electronic device 200 to be used in the identified electronic device 200 And a control code set.

Each of the blocks of the identification device 100 includes an infrared transmission unit 110 and a diode or the like for transmitting infrared light so that a control signal such as a remote control signal is transmitted by infrared rays under the control of the control unit 170.

The control signal transmitted in this manner is a control signal that is configured in a format capable of recognizing the control signal in the specific electronic device 200 selected by the control unit 170 and is capable of controlling sound in the selected specific electronic device 200. [

The sound signal receiving unit 120 receives a sound signal around the identification device 100. [ The sound signal receiving unit 120 may include a sound sensor for sensing a microphone or sound, and may further include an amplifier and an analog-to-digital converter (ADC).

The sound signal received through the sound signal receiving unit 120 is provided to the control unit 170 as digital data so that the control unit 170 allows the specific electronic equipment 200 selected or explicitly specified by the user So that it is possible to identify whether the electronic device 200 is the electronic device 200 or not.

The storage unit 130 stores various programs and data including a volatile memory and / or a nonvolatile memory. The storage unit 130 stores a program for identifying the electronic device 200, for example, to perform the method according to the present invention, and stores various data to be used in the identification program.

For example, the storage unit 130 may be used to output a control signal for controlling sound output from each electronic device 200 to all the electronic devices 200 that can be selected in the identification device 100 And may store a set of control codes to be used to control all or a particular selected electronic device 200.

In this case, the control data may include a data code (for example, an 8-bit code value) for performing the mute function and an electronic device 200 (For example, an 8-bit code value). The electronic device 200 having no audio output may further include a data code and a maker code for causing an immediate reaction (e.g., a beep) to occur. These data codes and further maker codes constitute a remote control code and can then be transmitted in infrared rays through the infrared transmitter 110 according to the format of each manufacturer

And the control code set can be dynamically downloaded in association with the remote server 400 and the identification program can also be downloaded through the download server 300. [

The wireless communication unit 140 is an interface for connecting to the communication network 500. The wireless communication unit 140 may include a modulator for receiving and transmitting a mobile communication signal such as CDMA, GSM, etc., or a short distance wireless signal such as Wi-Fi or Bluetooth for connecting to the communication network 500. And may be connected to the remote server 400 or the download server 300 through the wireless communication unit 140.

The input unit 150 is an interface for receiving an input from a user using the identification device 100. [ The input unit 150 may include a touch panel or a button, and may transmit the selected input of the touch panel or button to the control unit 170.

The output unit 160 is an interface for outputting data and signals such as video and audio to the user using the identification device 100. [ The output unit 160 may include, for example, a display, a speaker, a vibration element, and the like.

The control unit 170 controls each of the blocks of the identification device 100. The control unit 170 includes a CPU (Central Processing Unit), an MPU (Micro Processor), and the like, which includes one or more execution units capable of loading programs stored in the storage unit 130 and executing commands of the loaded programs. Processor Unit) or AP (Application Processor).

The control unit 170 may control the other blocks by loading the program stored in the storage unit 130 and executing the program.

For example, the control unit 170 loads the identification program stored in the storage unit 130 according to the user's selection, and performs the identification program so that the electronic device 200 designated by the user is connected to any electronic device 200 And controls the designated electronic device 200 through the infrared transmission unit 110 by loading a control code set corresponding to the identified electronic device 200. [

Here, the control code set may further include an output format (signal format) to be used for the remote control signal of the electronic device 200, including each data code and maker code for transmitting the remote control signal. This set of control codes is one package that can control the functions provided by the specific electronic device 200. [ Of course, it is not necessary to store all the control code sets for all the electronic devices 200 in the storage unit 130, and may receive and store them from the remote server 400 according to the identification of the electronic device 200 designated by the user.

If not all of the control code sets are stored in the storage unit 130, a data code for controlling the sound output of each electronic device 200 and a remote control code of the manufacturer code are stored in the storage unit 130, If the control code set is stored in the storage unit 130, a specific remote control code for a control signal to be transmitted for identification may be preliminarily designated, and further, Can be stored in advance.

Using the mapping information and designation information stored in the storage unit 130, the control unit 170 identifies which electronic device 200 is the electronic device 200 specified by the user's recognition or implicitly specified .

For example, the control unit 170 receives the selection of the type (audio deck, video player, air conditioner, TV, refrigerator, etc.) of the electronic device 200 to be identified through the input unit 150, It is possible to identify which electronic device 200 is the electronic device 200 designated by the electronic device 200 or to identify one or more electronic devices 200 200 can identify which electronic device 200 is connected.

The control unit 170 can identify the sound signal output from the designated electronic device 200 and controls the infrared ray transmitting unit 110 and the sound signal receiving unit 120 for this purpose. The control unit 170 also downloads the remote control code set itself or a control code set including the remote control code set from the remote server 400 through the wireless communication unit 140 using the ID of the identified electronic device 200 .

The controller 170 can automatically select a specific one or more electronic devices 200 according to a comparison of sound signals without a direct selection input by a user. Further, the user inputs an input through which the selection is confirmed or one of the selected electronic devices 200 through the input unit 150, and accordingly, the control unit 170 controls the operation of a specific one of the electronic devices 200 The remote control code set can be mapped to the designated electronic device 200.

The detailed control flow performed by the controller 170 will be described in more detail with reference to FIGS. 3 through 5. FIG.

The connection unit 180 may be a parallel bus, a serial bus, or a general purpose input output (GPIO) input / output for transmitting / receiving data of each block of the identification apparatus 100.

Here, the infrared transmitting unit 110 transmits the control signal, but the present invention is not limited thereto. For example, according to the development of electronic technology, the electronic devices 200 can be equipped with wireless communication technologies such as Wi-Fi, wireless LAN, Zigbee, etc., so that the wireless communication unit 140 performs functions of the infrared transmission unit 110 The identification device 100 may be configured.

Fig. 3 is a diagram showing an exemplary control flow in the identification apparatus 100. Fig.

This control flow of FIG. 3 may be performed on the identification device 100 of FIG. 2 and may be accomplished by controlling each of the blocks by the controller 170. The control unit 170 may start loading the identification program stored in the storage unit 130 (S100), and may terminate the identification program through a user input (S200).

Here, this identification program may be a program supplied by the manufacturer of the identification apparatus 100 or an application program (for example, App) downloadable through the download server 300 or the like.

First, after the loading of the identification program, the user inputs an identification request of the electronic device 200 through the input unit 150. In this process, the user can input the type of the electronic device 200 or omit inputting the type of the electronic device 200. [ In the case of inputting the type of the electronic device 200, identification is made in the selectable electronic devices 200 only for the type of the electronic device 200. Otherwise, all the selectable electronic devices 200 stored in the storage device 130 200 may be identified.

Thereafter, in step S110, the controller 170 selects one of the electronic devices 200 to be identified and selects a corresponding remote control code.

In step S120, the level data of the sound signal received through the sound signal receiving unit 120 (for example, the 16-bit data value received through the ADC) is written to the storage unit 130 under the control of the controller 170 do. This step S120 may be omitted (refer to FIG. 5 below) if the selected electronic device 200 does not have an audio output. In this step S120, the received level data value or its average value may be periodically received within a predetermined time (for example, one second) and recorded in the storage unit 130. [

Thereafter, in step S130, a remote control code mapped to the electronic device 200 selected in step S110 is generated according to the designated output format, and is transmitted through the infrared transmission unit 110 as a control signal.

This control signal may be a so-called remote control signal, and is a signal for controlling the sound output from the electronic device 200 selected in the identification device 100. For example, the control signal may be a signal indicating the cancellation of the sound, the release of the muting, or a signal for outputting a beep sound. If the selected electronic device 200 is different from the designated electronic device 200, the designated electronic device 200 will not respond to the control signal.

Thereafter, in step S140, the sound signal receiving unit 120 receives the sound signal, periodically converts the sound signal into level data, and transmits the level data to the control unit 170. The control unit 170 may then store the level data in the storage unit 130. [

Thereafter, in step S150, the control unit 170 determines whether the designated electronic device 200 implied or intended by the user based on the received sound signal, specifically the level data, is the electronic device 200 selected in step S110, ≪ / RTI >

For this identification, the controller 170 may compare the level data received and stored in step S120 with the level data received in step S140 to identify whether the designated electronic device 200 is the selected electronic device 200. [ In this process, the controller 170 calculates the difference between the two levels of data, and determines whether the difference is equal to or higher than the threshold level.

In a situation where the designated electronic device 200 outputs audio through a speaker, output of audio is generally cut off by a control signal such as mute, resulting in a difference in level data. It is possible to easily identify the electronic device 200 by experiment or by a threshold level determined according to the size of the level data of the sound signal received in advance or in step S120.

If the designated electronic device 200 does not have audio output, the determination may be made using the level data of the sound signal received and stored in step S140. For example, the electronic device 200 periodically and continuously receives the sound signal, It is possible to identify whether the designated electronic device 200 is the selected electronic device 200 based on the change in the time axis of the selected electronic device 200. [

A more specific control flow of the selected electronic device 200 for these two types will be described in more detail with reference to FIGS. 4 and 5. FIG.

The identification of the electronic device 200 in this step S150 may be to identify a specific electronic device 200 of a particular manufacturer or to identify a specific manufacturer (or maker).

In step S160, the controller 170 determines whether the currently selected electronic device 200 is the designated electronic device 200 to be identified by the user according to the identification result in step S150, The flow advances to step S170. Otherwise, the flow advances to step S180.

Of course, according to a modification of the application for identification, even if all of the electronic devices 200 are selected to be identified and then the electronic device 200 selected to be selectable by the user is the designated electronic device 200 The process may proceed to step S180. In this case, selection and comparison of all of the selectable electronic devices 200 in step S110 is completed, and then the result is displayed to the user through the output unit 160, and then the user can select the result.

Thereafter, in step S180, the electronic device 200 different from the electronic device 200 selected first in step S110 is selected again from the selectable electronic devices 200, and then the process proceeds to step S120. As a result, the test using the sound signal for another selected electronic device 200 proceeds and steps S120 to S160 are repeated.

In step S170, the controller 170 determines a set of control codes for the selected electronic device 200. In this process, the electronic device 200 selected according to the data communication through the wireless communication unit 140 with the remote server 400, Lt; RTI ID = 0.0 > a < / RTI >

Accordingly, the control unit 170 loads and displays the received or previously stored control code set, and transmits the control signal requested by the user through the infrared transmission unit 110 according to the user's selection.

FIG. 4 is a diagram illustrating an exemplary and specific control flow of step S150 of FIG. 3 for an electronic device 200 having an audio output. The control flow of FIG. 4 is performed for the electronic device 200 having the audio output, and the information about the type is stored in the storage unit 130 in correspondence with the electronic device 200, Or may be directly identified by the data code of the code.

4 is started (S151-1) as the step S150 of FIG. 3 starts and ends (S159-1) by completing the execution of the control flow of FIG. 4 and is performed by the control unit 170 directly, May be controlled by the control unit 170.

First, in step S152-1, the controller 170 determines the difference between the level data of the sound signal received in step S120 and the level data of the sound signal received in step S140.

Here, the level data may be an average value of the sound signal received during a predetermined time for receiving the sound signal in steps S120 and S140, or a value of the sound signal at a specific time.

Then, in step S153-1, it is determined whether or not the difference is equal to or higher than the threshold level. The threshold level here can be configured in various forms. For example, the threshold level may be a predetermined level value through an experiment or the like, or may be a level value determined from the level data from the level data of the sound signal received in step S120.

For example, when the value of the level data received in step S120 has a small size, a relatively small value is determined as the threshold level, and when the value of the level data is relatively large, the large value may be determined as the threshold level.

If it is less than the threshold level in step S153-1, the process shifts to step S159-1 and ends. It is determined that the designated electronic device 200 does not respond to the control signal of the selected remote control code.

If it is equal to or higher than the threshold level, the process proceeds to step S154-1 where a control signal such as a remote control signal of a remote control code capable of controlling the output sound of the currently selected electronic device 200 is controlled by the infrared transmission unit 110 Re-transmit. On the other hand, if the threshold level is equal to or higher than the threshold level, the process may directly shift to step S 158 - 1 as another modified example.

The control signal sent here may be the same signal as the control signal sent out in step S130 and may be a remote control signal, for example, for muting or de-mute (generally by toggling by the electronic device 200) .

Then, in step S155-1, the level data is received through the sound signal receiving unit 120, and temporarily stored in the storage unit 130.

Thereafter, in step S156-1, the difference between the level data of the sound signal in step S155-1 and the level data of the sound signal in step S120 is determined.

In step S157-1, it is determined whether or not the level difference is equal to or less than the specified threshold level. The threshold level here may be different from the threshold level in step S153-1. The determination in step S157-1 may be made to determine whether the sound level is the same, so that it is possible to configure a difference level of a certain magnitude with respect to the sound level in step S120, for example, to be set to a threshold level of a fixed size .

Then, in accordance with the determination in step S157-1, if it is equal to or lower than the threshold level, the electronic device 200 that has transitioned to step S158-1 is determined as the designated electronic device 200. [

On the other hand, if the determination in step S157-1 exceeds the threshold level, the process proceeds to step S159-1 and terminates, or to step S154-1 or to step S120, and repeats several times over several times. The electronic device 200 designated in step S158-1 may be determined.

4, the identification device 100 can automatically and electronically communicate with the electronic device 200 using the sound signal that the electronic device 200 can respond to without the input, setting, or searching by the user, So that the device 200 is identifiable and accordingly a corresponding set of control codes is determined and made available.

5 is a diagram illustrating an exemplary and specific control flow of step S150 of FIG. 3 for an electronic device 200 that does not have an audio output.

The control flow of FIG. 5 is performed for the electronic device 200 having no audio output, and the information about the type is stored in the storage unit 130 as being mapped to the electronic device 200 or may be stored in the remote control code As shown in FIG.

5 is started (S151-2) as the step S150 of FIG. 3 starts and ends by completing the execution of the control flow of FIG. 5 (S159-2) May be controlled by the control unit 170.

First, in step S152-2, the control unit 170 identifies a beep from the level data of the sound signal continuously received on the time axis in step S140.

Such a beep can be output by the electronic device 200 designated as a response or response to the transmission of the control signal in step S130, and is output during the output time (for example, a sound output such as 'ding dong' for one second).

The continuously received level data is data stored and received for a period of time (for example, two seconds, etc.) including the beep, from which the identification of the beep can be made in various ways.

For example, the values of the level data stored on the time axis are compared with each other, and the duration of the level data having a difference equal to or greater than a predetermined size is identified as the same or similar to the output time as described above, It is also possible to identify the beeping sound as to whether a frequency corresponding to the beep exists. There are other ways to identify these beeps.

If it is discriminated at step S153-2 through the identification, the process proceeds to step S154-2. Otherwise, the process returns to step S159-2 and terminates.

In step S154-2, the control unit 170 controls the infrared transmission unit 110 and the like to transmit a control signal such as a remote control signal capable of controlling the sound output from the selected electronic device 200 again. The control signal transmitted here may be the same as the control signal transmitted in step S130.

In step S155-2, the control unit 170 continuously receives the level data of the sound signal through the sound signal receiving unit 120 according to a predetermined period, and stores the received level data in the storage unit 130. [

Thereafter, in step S156-2, a signal sound is identified again from the level data of the sound signals continuously received in step S155-2 as in step S152-2.

These steps S154-2 to S156-2 are repeated according to the determination according to the set repetition times (step S157-2). Such a repetition number may be set at the start of Fig.

After iteration according to the repetition number, it is determined whether the electronic device 200 selected in step S158-2 is the designated electronic device 200. [ This determination can be made by the principle of majority vote in this process, and then the process goes to step S159-2 and ends. And steps S154-2 to S157-2 based on the number of repetitions may be omitted.

5, the identification device 100 automatically and without the need for input, setting, or searching by the user, uses the sound signal that the electronic device 200, which does not have a speaker or the like, can respond to So that the electronic device 200 can be conveniently identified and accordingly a corresponding set of control codes can be determined and used.
