[0001] The present disclosure relates to a method for providing content-related information and a method for providing a wake-up signal.

[0002] For example, a technology is being developed and applied to provide information related to content being played on content playback devices such as set-top boxes, digital TVs, and personal computers (hereinafter referred to as content-related information) through users' mobile terminals such as smartphones and tablet computers.

[0003] For example, in Korean Patent Registration No. 10-1716617 (prior document 1), a technology utilizing augmented reality is disclosed so that when home shopping content is being played on a content playback device, a viewer (user) of home shopping content can receive content-related information through the user's mobile terminal.

[0004] However, according to the technology disclosed in Korean Patent No. 10-1716617, there is a drawback in that users must perform complex tasks, such as running an augmented reality application and then taking a picture of the screen of the home shopping content, in order to receive content-related information.

[0005] Accordingly, the need for technology that can easily provide various content-related information related to content being played on a content playback device through a mobile terminal is increasing.

[0009] The purpose of the technology described in the present disclosure is to provide a method for providing content-related information, which can accurately and efficiently provide content-related information through a mobile terminal based on the correspondence between a user's mobile terminal and a content playback device and an ultrasonic characteristic signal transmitted using ultrasonic waves without requiring a complicated operation by the user, and can also prevent content-related information from being provided through a terminal unrelated to the content playback device, and can minimize the load on the processing of the mobile terminal and save power by switching the state of the mobile terminal based on a wake-up signal.

[0010] Another object of the technology described in the present disclosure is to provide a method for providing a wake-up signal, which accurately and efficiently identifies a mobile terminal that will provide information related to content being played on a content playback device based on a correspondence between a user's mobile terminal and a content playback device, generates a wake-up signal capable of switching the state of the mobile terminal so that the mobile terminal can receive and process ultrasonic characteristic signals transmitted using ultrasonic waves, and transmits the wake-up signal to the mobile terminal, thereby enabling the information related to the content to be accurately and efficiently provided through the mobile terminal, and also enables the information related to the content to be prevented from being provided through a terminal unrelated to the content playback device, and minimizes the load on the processing of the mobile terminal and saves power by switching the state of the mobile terminal based on the wake-up signal.

[0022] <Example 1>

[0023] Hereinafter, a method for providing content-related information according to a first embodiment of the technology described in the present disclosure is described.

[0024] FIG. 1 is an exemplary flowchart of a method for providing content-related information according to a first embodiment of the technology described in the present disclosure, FIG. 2 is a diagram illustrating a schematic configuration of a mobile terminal executing the method for providing content-related information according to the first embodiment of the technology described in the present disclosure, and FIG. 3 is a diagram illustrating an environment in which a mobile terminal executing the method for providing content-related information according to the first embodiment of the technology described in the present disclosure is placed.

[0025] First, referring to FIG. 2, a mobile terminal (100) executing a content-related information providing method according to a first embodiment of the technology described in the present disclosure will be described.

[0026] A mobile terminal (100) refers to a user's mobile terminal, such as a smart phone or tablet computer.

[0027] Referring to FIG. 2, a mobile terminal (100) executing a content-related information providing method according to the first embodiment of the technology described in the present disclosure may include a communication interface (110), an operation processing unit (130), and a storage unit (150).

[0028] The communication interface (110) performs communication with other devices, such as the computing device (300) illustrated in FIG. 3, using a wireless communication network and a mobile communication network. The communication interface (110) may be implemented by a semiconductor device such as a communication chip.

[0029] The operation processing unit (130) can be implemented by semiconductor devices such as a central processing unit (CPU), a graphics processing unit (GPU), and an application specific integrated circuit (ASIC).

[0030] The operation processing unit (130) may be implemented using, for example, a plurality of semiconductor elements. For example, the operation processing unit (130) may be implemented using a first semiconductor element that performs a communication function, a second semiconductor element that performs operation processing, and a third semiconductor element that generates location information of the mobile terminal (100) based on a GPS signal.

[0031] The operation processing unit (130) executes the content-related information providing method according to the first embodiment, and may also control the communication interface (110) and the storage unit (150) to execute the content-related information providing method according to the first embodiment.

[0032] The storage unit (150) stores data. The storage unit (150) may be implemented using a semiconductor device, such as a semiconductor memory. The storage unit (150) may store, for example, network identification information of the mobile terminal (100) described below. The storage unit (150) may also be implemented using, for example, a plurality of semiconductor memories.

[0033] Next, referring to FIG. 3, the environment in which the mobile terminal (100) is placed will be described.

[0034] Referring to FIG. 3, a mobile terminal (100) is connected to a computing device (300) via at least one of a wireless communication network (e.g., a wireless LAN) and a mobile communication network (e.g., an LTE or 5G communication network). Hereinafter, unless otherwise specifically distinguished, the wireless communication network and the mobile communication network are collectively referred to as a wireless communication network.

[0035] Additionally, the mobile terminal (100) may be connected to the content playback device (200) via a wireless communication network. Additionally, the mobile terminal (100) is configured to receive and process ultrasonic characteristic signals transmitted using ultrasonic waves from the content playback device (200).

[0036] A content playback device (200) is a device that receives and signals-processes content from a content transmission device (400) using at least one of a broadcasting network and a communication network and provides the content so that it can be displayed. The content playback device (200) includes, for example, devices such as a digital television, a personal computer, and a set-top box. That is, the content playback device (200) may include not only a digital television or a set-top box that receives and signals-processes content provided in a broadcast format and provides it, but also a computing device that can execute an application that can receive and signals-process content through a communication network and provide it. The content playback device (200) may include, for example, devices such as a CTV (Connected TV) and an ATV (Addressable TV).

[0037] A computing device (300) is connected to a mobile terminal (100), a content playback device (200), and a content transmission device (400) via a wired or wireless communication network. The computing device (300) is configured to create a correspondence between the mobile terminal (100) and the content playback device (200), and to generate a wake-up signal and transmit it to the mobile terminal (100). The computing device (300) is described in more detail through a second embodiment of the technology according to the present disclosure, which will be described later.

[0038] A content transmission device (400) is a device configured to transmit content to a content playback device (200) using at least one of a broadcasting network and a communication network. The content transmission device (400) may be implemented using, for example, a plurality of devices.

[0039] The content playback device (200), the computing device (300), and the content transmission device (400) may be operated by the same entity, but may also be operated by different entities.

[0040] Referring to FIG. 1 below, a method for providing content-related information according to a first embodiment of the technology described in the present disclosure will be described in more detail.

[0041] Referring to FIG. 1, first, a mobile terminal (100) receives a wake-up signal from a pre-designated computing device (300) (step S110).

[0042] The wake-up signal is generated by the computing device (300) and is generated using at least the correspondence between the mobile terminal (100) and the content playback device (200) and the identification information of the content being played by the content playback device (200).

[0043] FIG. 4 is a drawing exemplarily showing a correspondence relationship between a mobile terminal and a content playback device in a method for providing content-related information according to a first embodiment of the technology described in the present disclosure.

[0044] Referring to FIG. 4, for example, a relationship is shown in which a content playback device (200) corresponds to a first mobile terminal (100-1) and a second mobile terminal (100-2), but does not correspond to a third mobile terminal (100-3).

[0045] The correspondence relationship may represent a relationship in which a mobile terminal (100) and a content playback device (200) are included in the same network group or are placed within a pre-specified area more than a pre-specified number of times during a pre-specified period of time.

[0046] For example, referring to FIG. 4, it shows that a first mobile terminal (100-1) and a content playback device (200) are included in the same network group or are placed within a pre-designated area 30 times in one month, a second mobile terminal (100-2) and a content playback device (200) are included in the same network group or are placed within a pre-designated area 20 times in one month, and a third mobile terminal (100-3) and a content playback device (200) are included in the same network group or are placed within a pre-designated area twice in one month. In this case, for example, if the mobile terminal (100) and the content playback device (200) are included in the same network group or are placed within a pre-designated area more than 10 times during one month, the computing device (300) can create a correspondence relationship in which the content playback device (200) corresponds to the first mobile terminal (100-1) and the second mobile terminal (100-2), but does not correspond to the third mobile terminal (100-3).

[0047] The purpose of generating a correspondence relationship is to more accurately identify the target to which information related to the content being provided by the content playback device (200) (hereinafter referred to as "content-related information") will be provided. For example, since the third mobile terminal (100-3) is included in the same network group or is located within a pre-designated area twice within one month, it can be assumed that it is coincidentally included in the same network group as the content playback device (200) or is located within a pre-designated area. Therefore, the third mobile terminal (100-3) is excluded from the target to which content-related information will be provided.

[0048] That is, the first mobile terminal (100-1) and the second mobile terminal (100-2) can each operate as a mobile terminal (100), but the third mobile terminal (100-3) cannot operate as a mobile terminal (100).

[0049] More specifically, the correspondence relationship is generated by the computing device (300) using at least one of the network identification information and location information of the mobile terminal (100) and at least one of the network identification information and location information of the content playback device (200).

[0050] The network identification information of the mobile terminal (100) may be, for example, IP address information of the mobile terminal (100). The network identification information of the content playback device (200) may be, for example, IP address information of the content playback device (200).

[0051] If the mobile terminal (100) and the content playback device (200) are connected to the same network access device, such as an access point (AP), the IP address information of the mobile terminal (100) and the content playback device (200) may be identical when viewed from the outside. Accordingly, based on the IP address information of the mobile terminal (100) and the IP address information of the content playback device (200), the computing device (300) can determine whether the mobile terminal (100) and the content playback device (200) are included in the same network group.

[0052] Additionally, the computing device (300) can use the location information of the mobile terminal (100) and the location information of the content playback device (200) to determine whether the mobile terminal (100) and the content playback device (200) are placed within a pre-designated area.

[0053] The location information of the mobile terminal (100) can be obtained using, for example, GPS information, and the location information of the content playback device (200) can be obtained using location information extracted from address information obtained in advance or network identification information of the content playback device (200).

[0054] Accordingly, the method for providing content-related information according to the first embodiment of the technology described in the present disclosure may further include, before step S110, a step (S150) of transmitting at least one of network identification information and location information of the mobile terminal (100) to the computing device (300). That is, so that the computing device (300) can generate the aforementioned correspondence relationship, the mobile terminal (100) transmits at least one of network identification information and location information of the mobile terminal (100) to the computing device (300).

[0055] Step S150 may be performed, for example, at regular intervals, when the network identification information of the mobile terminal (100) changes, or when the location information of the mobile terminal (100) indicates that the mobile terminal (100) and the content playback device (200) are located within a pre-designated area.

[0056] As described above, the wake-up signal is generated using at least the corresponding relationship between the mobile terminal (100) and the content playback device (200) and the identification information of the content being played in the content playback device (200).

[0057] More specifically, the wake-up signal may be generated when the mobile terminal (100) and the content playback device (200) are determined to be currently included in the same network group or are determined to be located within a pre-designated area.

[0058] For example, even if the correspondence relationship indicates that the mobile terminal (100) (e.g., the first mobile terminal (100-1)) and the content playback device (200) correspond, if the mobile terminal (100) is determined not to be currently included in the same network group or is determined not to be located within a pre-designated area, the computing device (300) does not generate a wake-up signal because there is no need to provide content association information through the mobile terminal (100).

[0059] Whether the mobile terminal (100) and the content playback device (200) are currently included in the same network group or are placed within a pre-designated area can be confirmed, for example, by using at least one of the network identification information and location information of the mobile terminal (100) described above and at least one of the network identification information and location information of the content playback device (200).

[0060] Next, the mobile terminal (100) switches the state of the mobile terminal (100) to a first state in which ultrasonic waves can be received and signal processed for a predetermined time in the wake-up signal based on the wake-up signal received through step S110 (step S120).

[0061] Within the wake-up signal, a pre-defined time can be specified in response to the content. That is, the pre-defined time can be specified in response to conditions such as the length of the content, the display time of products provided within the content, etc.

[0062] As described below, the ultrasonic characteristic signal is transmitted from the content playback device (200) to the mobile terminal (100) using ultrasonic waves.

[0063] For example, if the state of the mobile terminal (100) is always maintained in the first state capable of receiving and processing ultrasonic waves, the load on the computational processing of the mobile terminal (100) increases and the power of the mobile terminal (100) is consumed.

[0064] To prevent such cases, the mobile terminal (100) switches the state of the mobile terminal (100) to a first state in which ultrasonic waves can be received and signal processed for a predetermined time in a wake-up signal only when content-related information is provided, more specifically, only when an ultrasonic characteristic signal is scheduled to be transmitted from the content playback device (200) within a certain time.

[0065] Therefore, the load of the computational processing of the mobile terminal (100) can be minimized and power can be saved.

[0066] Next, the mobile terminal (100), in a state switched to the first state through step S120, checks whether it receives an ultrasonic characteristic signal transmitted based on content from the content playback device (200) for a predetermined time (step S130).

[0067] The ultrasonic characteristic signal may be included in the content, for example, and may be output using the audio output of the content playback device (200).

[0068] For example, an ultrasonic characteristic signal may be inserted into content by a computing device (300) or a content transmission device (400). Since the ultrasonic characteristic signal is an audio signal, it may be output using an audio output device, such as a speaker included in or connected to the content playback device (200). Therefore, even without adding a separate configuration, the content playback device (200) can output the ultrasonic characteristic signal using an audio output.

[0069] Although the ultrasonic characteristic signal is output using the audio output of the content playback device (200), the user (viewer) cannot perceive it because it is outside the audible frequency range. However, since the mobile terminal (100) is in a first state capable of receiving and signal processing ultrasonic waves, it can receive and signal process the ultrasonic characteristic signal.

[0070] In addition, since the content playback device (200) outputs ultrasonic characteristic signals using audio output, the ultrasonic characteristic signals can only be transmitted within a pre-specified range. In addition, if an obstacle (e.g., a wall) that impedes the transmission of ultrasonic waves exists between the content playback device (200) and the mobile terminal (100), the ultrasonic characteristic signals cannot be transmitted to the mobile terminal (100).

[0071] Therefore, for example, when a user views content output using a content playback device (200) and the mobile terminal (100) is placed close to the content playback device (200) (more specifically, close to the user), the ultrasonic characteristic signal can be transmitted to the mobile terminal (100).

[0072] Therefore, based on the correspondence between the mobile terminal (100) and the content playback device (100), it is possible to identify the mobile terminal (100) to provide information related to the content more accurately and efficiently by additionally utilizing the ultrasonic characteristic signal even when the mobile terminal (100) is designated.

[0073] Next, if it is confirmed that an ultrasonic characteristic signal has been received for a predetermined time through step S130, the mobile terminal (100) displays content-related information using the ultrasonic characteristic signal (step S140).

[0074] FIG. 5 is a drawing exemplarily showing an ultrasonic characteristic signal in a method for providing content-related information according to a first embodiment of the technology described in the present disclosure.

[0075] Referring to FIG. 5, the ultrasonic characteristic signal may include metadata regarding information associated with the content.

[0076] For example, metadata may include identification information of an application (generally referred to as an "app") to be executed on a mobile terminal (100) in response to content-related information, and identification information regarding a detailed screen of the application. Metadata may further include information such as identification information of the content and identification information of a channel providing the content. In this case, the mobile terminal (100) may execute and provide the application identified by the metadata, or execute and provide the application by displaying a detailed screen.

[0077] Information such as content identification information and channel identification information providing the content can be used when generating provision details in step S160 described below and transmitting them to a computing device (300).

[0078] The ultrasonic characteristic signal may also include a uniform resource locator (URL) for content-related information. In this case, the mobile terminal (100) may display and provide a web page corresponding to the URL using a mobile web browser.

[0079] Ultrasonic characteristic signals may also include deep links to content-related information. A deep link refers to a link that allows a user to land on a specific location within an application. For example, a deep link can be used to navigate to a specific page (screen) within an application, even if the application is not installed on the mobile terminal (100).

[0080] Content-related information may include at least one of detailed information about a product associated with the content provided by the content playback device (200) and purchase screen information for the product. For example, if the content is home shopping content, the content-related information may include detailed information about the product being promoted in the home shopping content or purchase screen information for the product.

[0081] Meanwhile, the method for providing content-related information according to the first embodiment of the technology described in the present disclosure may further include, after step S140, a step (step S160) of generating a provision history for the content-related information provided through step S140 and transmitting it to a computing device (300).

[0082] Accordingly, the computing device (300) can easily confirm that content-related information has been provided from the mobile terminal (100) based on the provision details.

[0083] Meanwhile, the method for providing content-related information according to the first embodiment of the technology described in the present disclosure may further include a step (step S170) of switching the state of the mobile terminal (100) from a first state to a second state in which ultrasonic signals are not processed or received, if it is determined in step S130 that an ultrasonic characteristic signal has not been received for a predetermined time.

[0084] That is, since there is no longer a need to receive ultrasonic characteristic signals, the mobile terminal (100) switches to a second state in which ultrasonic signals are not processed or received through step S170. Accordingly, the load on the computational processing of the mobile terminal (100) can be minimized and power can be saved.

[0085] As described above, according to the first embodiment, the mobile terminal (100) can receive a wake-up signal generated using the corresponding relationship and content identification information, switch to a first state based on the wake-up signal, receive an ultrasonic characteristic signal, and display content association information using the ultrasonic characteristic signal.

[0086] Accordingly, even without complex operations on the part of the user, based on the correspondence between the user's mobile terminal (100) and the content playback device (100) and the ultrasonic characteristic signals transmitted using ultrasonic waves, information related to the content can be accurately and efficiently provided through the mobile terminal (100). In addition, information related to the content can be prevented from being provided to a terminal unrelated to the content playback device (200). In addition, since the state of the mobile terminal (100) is switched to a state in which the ultrasonic characteristic signals transmitted using ultrasonic waves can be received and processed only when necessary, the load on the computational processing of the mobile terminal (100) can be minimized and power can be saved.

[0087] <Example 2>

[0088] Hereinafter, a method for providing a wake-up signal according to a second embodiment of the technology described in the present disclosure is described.

[0089] In the wake-up signal providing method according to the second embodiment of the technology described in the present disclosure, a detailed description of the same or similar configuration as that of the first embodiment is omitted.

[0090] FIG. 6 is a drawing exemplarily showing a method for providing a wake-up signal according to a second embodiment of the technology described in the present disclosure, and FIG. 7 is a drawing schematically showing a configuration of a computing device that executes the method for providing a wake-up signal according to the second embodiment of the technology described in the present disclosure.

[0091] First, referring to FIG. 7, a computing device (300) executing a wake-up signal providing method according to a second embodiment of the technology described in the present disclosure is described.

[0092] Referring to FIG. 7, a computing device (300) executing a wake-up signal providing method according to the second embodiment of the technology described in the present disclosure may include a communication interface (310), an operation processing unit (330), and a storage unit (350).

[0093] The communication interface (310) performs communication with other devices, such as the mobile terminal (100), content playback device (200), and content transmission device (400) illustrated in FIG. 3, using a wired or wireless communication network. The communication interface (310) may be implemented by a semiconductor device such as a communication chip.

[0094] The operation processing unit (330) can be implemented by semiconductor devices such as a CPU, GPU, and ASIC.

[0095] The operation processing unit (330) may be implemented using, for example, a plurality of semiconductor elements. For example, the operation processing unit (330) may be implemented using a first semiconductor element that performs a communication function and a second semiconductor element that performs operation processing.

[0096] The operation processing unit (330) executes the wake-up signal providing method according to the second embodiment, and may also control the communication interface (310) and the storage unit (350) to execute the wake-up signal providing method according to the second embodiment.

[0097] The storage unit (350) stores data. The storage unit (350) may be implemented using a semiconductor device, such as a semiconductor memory. The storage unit (350) may store, for example, a correspondence relationship between a mobile terminal (100) and a content playback device (100). The storage unit (350) may also be implemented using, for example, a plurality of semiconductor memories.

[0098] Referring to FIG. 6 below, a method for providing a wake-up signal according to a second embodiment of the technology described in the present disclosure will be described in more detail.

[0099] Referring to FIG. 6, first, the computing device (300) creates a correspondence relationship between the mobile terminal (100) and the content playback device (200) (step S210).

[0100] As described above, the correspondence between the mobile terminal (100) and the content playback device (200) is created by the computing device (300) using at least one of the network identification information and location information of the mobile terminal (100) and at least one of the network identification information and location information of the content playback device (200).

[0101] More specifically, the correspondence relationship may represent a relationship in which a mobile terminal (100) and a content playback device (200) are included in the same network group or are placed within a pre-specified area more than a pre-specified number of times during a pre-specified period of time.

[0102] Since the corresponding relationship can be referred to the first embodiment described above, a detailed description is omitted.

[0103] Next, the computing device (300) generates a wake-up signal that switches the state of the mobile terminal (100) to a first state capable of receiving and processing ultrasonic waves for a predetermined period of time using the corresponding relationship generated through at least step S210 and the identification information of the content being played in the content playback device (200) ((step S220).

[0104] Identification information of content being played in the content playback device (200) can be obtained, for example, through communication with the content playback device (200).

[0105] A wake-up signal may be generated when the mobile terminal (100) and the content playback device (200) are determined to be currently included in the same network group or are determined to be located within a pre-designated area.

[0106] The wake-up signal can refer to the first embodiment described above, so a detailed description is omitted.

[0107] Next, the computing device (300) transmits the wake-up signal generated through step S220 to the mobile terminal (100) (step S230).

[0108] For example, a computing device (300) transmits a wake-up signal to a mobile terminal (100) via a wireless communication network.

[0109] Meanwhile, the computing device (300) can receive provision details for information provided by the mobile terminal (100) in connection with content from the mobile terminal (100) (step S240).

[0110] The second embodiment can refer to the first embodiment described above, so a detailed description thereof is omitted.

[0111] As described above, according to the second embodiment, the computing device (300) generates a wake-up signal using the corresponding relationship and content identification information and transmits it to the mobile terminal (100).

[0112] Accordingly, the mobile terminal (100) can be switched to the first state based on the wake-up signal, receive the ultrasonic characteristic signal, and display content-related information using the ultrasonic characteristic signal.

[0113] Accordingly, information related to content can be accurately and efficiently provided through a mobile terminal (100). In addition, information related to content can be prevented from being provided from a terminal unrelated to the content playback device (200). In addition, since the state of the mobile terminal (100) is switched to a state capable of receiving and processing ultrasonic characteristic signals transmitted using ultrasonic waves only when necessary, the load on the computational processing of the mobile terminal (100) can be minimized and power can be saved.
