[0027] FIG. 1 illustrates the configuration of an online purchasing system (10) according to one embodiment of the present invention.

[0028] Referring to FIG. 1, an online purchasing system (10) according to one embodiment of the present invention may include a terminal device (100), a content providing device (200), and an access point (300).

[0029] The terminal device (100) can execute various types of applications and can provide the application currently in execution to the user by displaying it visually or audibly. The terminal device (100) may include a display unit for visually displaying the application, an input unit for receiving user input, a communication unit, a memory in which at least one program is stored, and a processor.

[0030] The terminal device (100) may be a mobile terminal such as a smartphone or tablet PC, and depending on the embodiment, may also include a fixed device such as a desktop. Specifically, the terminal device (100) may include a mobile phone, a smartphone, a laptop computer, a digital broadcasting terminal, a PDA (personal digital assistants), a PMP (portable multimedia player), a slate PC, a tablet PC, an ultrabook, a wearable device (e.g., a smartwatch, a smart glass, a head-mounted display), etc.

[0031] The terminal device (100) may be connected to the internet, etc., through a communication network, and the communication network connectable to the terminal device (100) may include a wired network and a wireless network. Specifically, the terminal device (100) may support various communication networks such as a wired internet network, Wi-Fi (Wireless Fidelity), WiBro (Wireless Broadband Internet), Bluetooth, and a mobile communication network. However, the communication network according to the present invention is not limited to the networks listed above and may include a known wireless data network, a known telephone network, a known wired or wireless television network, etc.

[0032] The content providing device (200) is a device capable of providing various content to a user, such as home shopping videos, movies, dramas, photos, and sound, and may be a television, monitor, speaker, etc. However, it is not limited to this, and any device capable of providing various content to a user, such as a kiosk or an outdoor electronic display, may be considered as the content providing device (200).

[0033] Here, the content providing device (200) may transmit a wireless signal containing product information for a preset target product. According to an embodiment, if a target product appears within the content currently being output by the content providing device (200), it is also possible to transmit a wireless signal corresponding to the target product. For example, the content providing device (200) may output content such as home shopping, and may transmit product information for a target product appearing in the home shopping via a wireless signal.

[0034] In this case, the terminal device (100) can extract product information regarding the target product of the home shopping currently being displayed based on a wireless signal received from the content providing device (200), and can provide the extracted product information to the user by outputting it within the terminal device (100). That is, the user can easily obtain product information regarding the target product displayed on the content providing device (200) through the terminal device (100), and can conveniently perform the purchase procedure for the target product based on this information.

[0035] For example, as illustrated in FIG. 2, a separate server (S) may first transmit to a content provider (200) a URL (including a tracking code) containing the name of a merchant selling the target product, detailed product information of the product, and broadcast time information of the content corresponding to the target product (S10).

[0036] Accordingly, the content providing device (200) can convert information received from the server (S) into a wireless signal in an inaudible frequency band and transmit it to the terminal device (100) when viewing the content (S20). Here, the content providing device (200) can provide content such as home shopping channels, movies, and dramas to the user, and during the provision of content, in addition to the sound signal, transmit a wireless signal containing information about home shopping products or target products appearing in the movies, dramas, etc. At this time, the wireless signal can be transmitted as an inaudible sound wave in a frequency band of 18,500 Hz to 24,000 Hz, which is a frequency band that ordinary users cannot hear.

[0037] Next, when a user performs a predetermined setting operation (e.g., shaking up and down) while running an application for online purchase on a terminal device (100), such as a smartphone (S30), the terminal device (100) can calculate product information for a product included in a wireless signal and open a homepage, etc. corresponding to a URL for the product (S40). That is, as shown in FIG. 3(a), the terminal device (100) can run a pre-installed application (1000), and when the setting operation is performed, the terminal device (100) can provide a push message (1010) to the user to confirm whether to move to a product information site of a specific URL. Afterwards, when the user selects, such as by clicking the push message, as shown in FIG. 3(b), the terminal device (100) can use the URL information to access a site where product information for the product is provided and can be purchased.

[0038] Accordingly, the server (S) can proceed with the payment process for the product (S50), check the tracking code (S60), and transmit result data regarding the success or failure of the purchase of the product to the terminal (100) (S70). That is, it can induce the user to more easily proceed with the purchase of the product currently being broadcast.

[0039] The access point (300) can form a local area network (LAN) within a set area, and depending on the embodiment, can simultaneously support a wired internet network and a wireless Wi-Fi network.

[0040] Here, the content providing device (200) can be connected to a wired or wireless communication network through an access point (300), and can receive and output content through the connected wired or wireless communication network.

[0041] Additionally, in the case of the terminal device (100), it may not be connected to the access point (300) when connected via a mobile communication network, but when using a Wi-Fi network, it may be connected to the local area network via the access point (300).

[0042] For example, a content providing device (200), such as an IPTV, may be provided in a home, and the IPTV may be connected to a wired internet network through an access point (300). Afterwards, the user may watch content such as home shopping through the IPTV while holding a terminal device (100), such as a smartphone, and in this case, the terminal device (100) may connect to a Wi-Fi network formed in the home through the access point (300).

[0043] Here, the wireless signal transmitted by the content provider (200) can be distributed to any terminal device (100) located nearby, and in some cases, inconvenience may occur, such as receiving an unnecessary wireless signal from a content provider (200) that the user does not want. To solve this, an online purchasing system according to an embodiment of the present invention can prevent the possibility of unnecessary communication with a content provider (200) that the user did not intend by checking the respective IP information, etc., before connecting the terminal device (100) and the content provider (200). Hereinafter, an online purchasing method according to an embodiment of the present invention will be described with reference to FIG. 4.

[0045] FIG. 4 illustrates a flowchart of an online purchasing method according to one embodiment of the present invention.

[0046] Referring to FIG. 4, the terminal device (100) can receive a wireless signal containing product information about a target product from a content providing device (200) (S110). For example, the content providing device (200) can output and provide content such as a home shopping channel, a movie, or a drama to a user, and at this time, the content providing device (200) can transmit a wireless signal during the provision of content. According to an embodiment, the wireless signal can be added to a voice signal included in the content and transmitted in the form of an inaudible sound wave.

[0047] When transmitting wireless signals as inaudible sound waves, frequencies in the range of 18,500 Hz to 24,000 Hz, which are inaudible to normal users, may be utilized, but are not necessarily limited thereto, and the frequency band of the wireless signal may be adjusted depending on the operating environment and application.

[0048] According to the embodiment, it is also possible to use a beacon signal or a BLE (Bluetooth Low Energy) signal as a wireless signal. In the case of BLE, it is one of the Bluetooth technologies that performs low-power, low-capacity data transmission and reception in a 2.4 GHz frequency band with a reach radius of about 10 meters, and the content provider device (200) can be implemented to transmit a BLE signal. Furthermore, it is also possible to implement the BLE signal as a high frequency or ultrasound and transmit it in an inaudible range.

[0049] Product information included in the wireless signal may include identification information for identifying the target product or the URL (Uniform Resource Locator) address of a web page for proceeding with the purchase of the target product. Here, the target product may include not only objects having a physical form but also various goods and services such as services or content.

[0050] According to an embodiment, product information for a plurality of products may be included in the wireless signal. That is, when a plurality of products appear in the content output by the content providing device (100), product information corresponding to each product may be included in the wireless signal. In this case, the terminal device (100) may select one or more of the plurality of products to proceed with the purchase procedure.

[0051] Afterward, the terminal device (100) can check whether the content provider (200) is connected to the same local area network as the terminal device (100) by using a wireless signal (S120). That is, the terminal device (100) can check whether the content provider (200) is a reliable device or a content provider (200) from which the user intends to receive a wireless signal, and can receive a wireless signal from the content provider (200) only if it is confirmed.

[0052] For example, as illustrated in FIG. 5, there may be cases where a single terminal device (100) receives wireless signals simultaneously from multiple content providers (200a, 200b). In this case, one may be an IPTV (200a) installed in the living room of one's own home, and the other may be an IPTV (200b) of a neighboring house. That is, since the wireless signal transmitted from the IPTV (200b) of the neighboring house is a wireless signal that the user does not want, it is necessary to restrict reception to only the wireless signal transmitted from one's own IPTV (200a), excluding this one.

[0053] To this end, the terminal device (100) can check whether the content provider device (200) is connected to the same local area network as the terminal device (100), and can determine that the content provider device (200) corresponds to a reliable content provider device (200) only if it is connected to the same local area network. That is, since the terminal device (100) is connected to its own access point (300a), such as its home or office, it can determine that the content provider device (200) is its own content provider device (200) only if it is also connected to the same access point (300a). Generally, since both the terminal device (100) and the content provider device (200) are connected to their own access point (300b), if they are connected to the same access point (300a), they can determine that it is a reliable content provider device (200).

[0054] According to an embodiment, it is also possible to determine whether the content provider device (200) is a reliable device based on the connection history of each access point to which the terminal device (100) is connected. That is, even if the terminal device (100) is not currently connected to an access point, the terminal device (100) may have a connection history of previously being connected to an access point such as its home or office. Therefore, by using the connection history, the access point to which the content provider device (200) is currently connected can be compared, and if the comparison result shows that the content provider device (200) is connected to an access point included in the terminal device (100)'s connection history, it can be determined to be a reliable device. That is, even if the terminal device (100) is not currently connected to an access point, the connection history can be used to determine that the content provider device (200) is connected to the same local area network.

[0055] On the other hand, if the access points (300a, 300b) to which the terminal device (100) and the content provider device (200b) connect are different, the wireless signal provided by the content provider device (200b) can be ignored because the content provider device (200b) corresponds to the IPTV of the neighboring house.

[0056] Specifically, when the content provider (200) transmits a wireless signal, it may include information about each access point (300a, 300b) to which the content provider (200a, 200b) is connected, and the terminal device (100) can verify this to distinguish the access points (300a, 300b) to which the content provider (200a, 200b) is connected. For example, the content provider (200) may include its own IP address information or SSID information, etc., in the wireless signal and transmit it.

[0057] In this case, the terminal device (100) can extract the IP address of the content provider (200) included in the wireless signal, and using the extracted IP address, can determine whether the IP address corresponds to the IP address provided by the access point (300) of the local area network to which the terminal device (100) is connected. If the IP address of the content provider (200) corresponds to the IP address of the access point to which the terminal device (100) is connected, it can be determined that they are connected to the same local area network.

[0058] Additionally, according to an embodiment, the terminal device (100) can extract the SSID of the access point (300) to which the content provider (200) is connected from a wireless signal, and can determine whether the extracted SSID matches the SSID of the access point (300) to which the terminal device (100) is connected. If the SSIDs match, it can be determined that they are connected to the same local area network.

[0059] Subsequently, if it is determined that the terminal device (100) is connected to the same local area network, the terminal device (100) can extract product information from the wireless signal and display it within the terminal device (100) (S130). That is, by using a microphone or the like provided in the terminal device (100), the signal corresponding to the inaudible frequency range among the signals received can be demodulated according to a predetermined standard to produce product information for the target product. Here, the product information may include a URL address for the target product, and the terminal device (100) can use this to display a detailed product information page or a purchase homepage within the terminal device (100).

[0060] Accordingly, the user can conveniently obtain product information of target products included in the content currently being output using the terminal device (100), and can also proceed with the purchase process more conveniently.

[0061] According to an embodiment, it is also possible for the terminal device (100) to display product information only when a specific input from the user is authorized. That is, the user may not prefer to receive product information every time according to the wireless signal transmitted by the content provider (100), and may want to receive product information only when the target product they want appears. Accordingly, the terminal device (100) may display product information within the terminal device (100) only when a specific input from the user is authorized.

[0062] Specifically, when the terminal device (100) determines that the content provider device (200) is connected to the same short-range communication network as the terminal device (100), it can determine whether a user's predetermined set action is input to the terminal device (100). That is, the user's movement can be detected using a sensor (not shown) provided within the terminal device (100), and the terminal device (100) can determine whether the detected user's movement corresponds to a set action. For example, when using a smartphone or the like as the terminal device (100), the terminal device (100) may be equipped with various sensors, such as a gyroscope sensor, capable of detecting the user's movement, and accordingly, the terminal device (100) can detect the user's movement using the sensor and determine whether the user's movement corresponds to a predetermined set action.

[0063] Here, if the setting operation is defined as shaking the terminal device (100) up and down or left and right, the terminal device (100) collects sensor data according to the user's movement using a gyroscope sensor, etc., and if the collected data matches or is similar to pre-defined comparison data by a certain level or more, it can be determined that the user's movement corresponds to a pre-determined setting operation.

[0064] Subsequently, when it is determined that a setting operation has been input, the terminal device (100) can extract product information from the wireless signal and display the product information within the terminal device (100). For example, if a user wishes to purchase a product while watching a home shopping channel, the user can receive product information about the target product on the home shopping channel or be directly connected to the purchase page of the target product, thereby allowing the user to proceed with the purchase process more conveniently, simply by performing a predetermined setting operation, such as shaking the terminal device (100), such as a smartphone.

[0065] Next, the terminal device (100) can proceed with the purchase procedure for the target product according to the user's input (S140). For example, the terminal device (100) can calculate a URL address where product information and purchase for the target product can be provided using a wireless signal received from the content provider (200), and can automatically connect to a web page corresponding to the URL address to provide product information and the purchase procedure for the target product to the user.

[0066] Additionally, according to the embodiment, it is possible to execute a specific application within the terminal device (100) to proceed with the purchase procedure for the target product. In this case, the wireless signal may include identification information indicating a specific application, and if such identification information is included, the terminal device (100) may execute the application. Here, the application may provide a detailed description page for the target product extracted from the wireless signal and a purchase procedure, etc.

[0068] FIG. 6 is a flowchart illustrating the operation of an online purchasing system according to an embodiment of the present invention. Referring to FIG. 6, first, a content providing device (200) can transmit a wireless signal to a terminal device (100). The wireless signal may include product information regarding a target product appearing in the content output by the content providing device (200), and information regarding a local area network to which the content providing device (200) is connected. Here, an example is provided in which the IP address of the content providing device (200) is included in the information regarding the local area network and transmitted, but depending on the embodiment, it is also possible to transmit the SSID of the local area network, etc.

[0069] Afterwards, the terminal device (100) can check whether the terminal device (100) is connected to a local area network, and if it is connected to a local area network, it can check whether the content provider device (200) is connected to the same local area network.

[0070] Here, if the terminal device (100) is not connected to a local area network, additional verification can be omitted, and product information included in the wireless signal can be extracted and displayed within the terminal device (100). That is, if the terminal device (100) is connected to a mobile communication network, etc., it is impossible to determine whether the terminal device (100) and the content provider (200) are connected to the same local area network, so product information can be extracted and displayed based on the received wireless signal without additional verification. However, according to the embodiment, even if the terminal device (100) is not connected to a local area network, it is also possible to determine whether the content provider (200) is connected to the same local area network based on the connection history of the access points of the terminal device (100).

[0071] Meanwhile, when the terminal device (100) is connected to a local area network, the IP address of the content provider (200) can be extracted from the wireless signal, and it can be determined whether the IP address corresponds to an IP address within the local area network. Here, if the IP address is not an IP address of the local area network to which the terminal device (100) is connected, processing of the wireless signal can be stopped. That is, since it corresponds to communication with the content provider (200) that the user did not intend, the wireless signal received from the content provider (200) can be ignored.

[0072] On the other hand, if the IP address of the content provider (200) corresponds to the IP address of the local area network to which the terminal device (100) is connected, it can be determined that this corresponds to communication with the content provider (200) intended by the user. Accordingly, product information can be extracted from the wireless signal and displayed within the terminal device (100). Subsequently, the terminal device (100) can proceed with the purchase procedure for the target product, etc., according to the user's input.

[0074] FIG. 7 is a configuration diagram of a content provision system according to an embodiment of the present invention.

[0075] Referring to FIG. 7, a content providing system (20) according to one embodiment of the present invention may include a terminal device (100), a content providing device (200), and an access point (300).

[0076] A terminal device (100) can receive an advertising message pushed from a server (not shown), and the user can select the advertising message by touching it, etc. Here, the advertising message may include product information regarding the target product, and the terminal device (100) can output a wireless signal containing the product information. The wireless signal output by the terminal device (100) may be an inaudible sound wave and may be output through a built-in speaker (not shown) of the terminal device (100). Depending on the embodiment, it is also possible to output the wireless signal as a beacon signal or a BLE signal.

[0077] Subsequently, the content providing device (200) can receive a wireless signal using a built-in microphone, etc., and can extract a target product from product information included in the wireless signal. In addition, the content providing device (200) can search for and output content corresponding to the extracted target product. For example, if the content providing device (200) is an IPTV, it is possible to change to a home shopping channel for the target product.

[0078] However, since the terminal device (100) distributes wireless signals to any content providing device (200) located nearby, inconvenience may occur, such as unnecessary wireless signals being transmitted to content providing devices (200) that the user does not want. To solve this, a content providing system (20) according to an embodiment of the present invention can prevent unnecessary communication with content providing devices (200) that the user did not intend by checking each IP information, etc., before connecting the terminal device (100) and the content providing device (200). Hereinafter, a content providing method according to an embodiment of the present invention will be described with reference to FIGS. 8 and FIGS. 9.

[0079] FIG. 8 is a flowchart of a content provision method according to an embodiment of the present invention, and FIG. 9 is a flowchart showing the operation of a content provision system according to an embodiment of the present invention.

[0080] Referring to FIGS. 8 and 9, the content providing device (200) can receive a wireless signal containing product information about a target product from the terminal device (100) (S210). The terminal device (100) can receive advertising messages, etc. from a separate server (not shown), and the user can select the advertising message by touching it. For example, the user can receive an advertising message containing phrases such as, "OO T-shirt is currently on sale on the AA Home Shopping channel, touch it to check the AA Home Shopping channel on IPTV," and the user can request the content providing device (200) to output the AA Home Shopping channel by touching the advertising message. In this case, the terminal device (100) can generate and transmit a corresponding wireless signal, and the content providing device (200) can receive the wireless signal. Here, the wireless signal may be transmitted in the form of inaudible sound waves.

[0081] Subsequently, the content provider (200) can use a wireless signal to check whether the terminal device (100) is connected to the same local area network as the content provider (200) (S220). That is, the content provider (200) can check whether the terminal device (100) is a reliable device, and can receive a wireless signal from the terminal device (100) only if it is confirmed.

[0082] For example, there may be cases where multiple terminal devices (100) simultaneously transmit wireless signals to the same content provider (200). In this case, one may be the user's terminal device (100), and the others may be terminal devices from a neighboring house. That is, since the wireless signal transmitted from the terminal device from the neighboring house is a wireless signal that the user does not want, it is necessary to exclude it and restrict reception to only the wireless signal transmitted from one's own terminal device (100).

[0083] To this end, the content providing device (200) can check whether the terminal device (100) is currently connected to the same local area network, and can determine that the terminal device (100) corresponds to a trusted terminal device (100) only if it is connected to the same local area network. Generally, since both the terminal device (100) and the content providing device (200) are configured to connect to an access point (300b) provided in one's home or office, if they are connected to the same access point (300a), they can be determined to be a trusted terminal device (100).

[0084] According to an embodiment, it is also possible to determine whether the content providing device (200) is a reliable device based on the connection history of the access points of the terminal device (100). That is, even if the terminal device (100) is not currently connected to an access point, the terminal device (100) may have a connection history of previously being connected to an access point such as its home or office. Therefore, by using the connection history, the content providing device (200) can be compared with the access point currently connected to it, and if the comparison result shows that the content providing device (200) is connected to an access point included in the connection history of the terminal device (100), it can be determined to be a reliable device. That is, even if the terminal device (100) is not currently connected to an access point, it can be determined that it is connected to the same local area network as the content providing device (200) by using the connection history.

[0085] On the other hand, if the access point (300) to which the terminal device (100) and the content provider device (200) connect is different, the wireless signal provided by the terminal device (100) can be ignored because the terminal device (100) corresponds to the terminal device of the neighboring house.

[0086] Specifically, when the terminal device (100) transmits a wireless signal, it may transmit the signal including information about the access point (300) to which the terminal device (100) is connected, and the content provider (200) may verify this to identify the access point (300) to which the terminal device (100) is connected. For example, the terminal device (100) may transmit the signal including its own IP address information or SSID information within the wireless signal. According to an embodiment, the terminal device (100) may transmit the signal including a connection history that includes the IP address information or SSID information of access points previously connected to it.

[0087] In this case, the content provider (200) can extract the IP address of the terminal device (100) included in the wireless signal, and using the extracted IP address, can determine whether the IP address corresponds to the IP address provided by the access point (300) of the local area network to which the content provider (200) is connected. If the IP address of the terminal device (100) corresponds to the IP address of the access point (300) to which the content provider (200) is connected, it can be determined that they are connected to the same local area network.

[0088] According to an embodiment, the content providing device (200) can extract the SSID of the access point (300) to which the terminal device (100) is connected from a wireless signal, and can determine whether the extracted SSID matches the SSID of the access point (300) to which the content providing device (200) is connected. Here, if the SSIDs match, it can be determined that they are connected to the same local area network.

[0089] Subsequently, if connected to the same local area network, the content providing device (200) can output content related to product information included in the wireless signal (S230). That is, the content providing device (200) can extract product information from the wireless signal and search for content in which a target product corresponding to the product information appears. In other words, among the various contents that the content providing device (200) can provide, it can search for and find content corresponding to the product information. After the search is completed, the content providing device (200) can output the searched content and provide it to the user. That is, it can output content regarding the target product that appeared in the advertisement message received by the user through the terminal device (100) and provide it to the user.

[0091] The present invention described above can be implemented as computer-readable code on a medium on which a program is recorded. The computer-readable medium may be one that continuously stores a program executable by a computer, or temporarily stores it for execution or download. Furthermore, the medium may be various recording or storage means in the form of a single or multiple hardware components, and is not limited to a medium directly connected to a computer system but may also exist distributed over a network. Examples of media may include magnetic media such as hard disks, floppy disks, and magnetic tapes; optical recording media such as CD-ROMs and DVDs; magneto-optical media such as floptical disks; and media configured to store program instructions, including ROM, RAM, and flash memory. Additionally, other examples of media may include recording or storage media managed by app stores that distribute applications or sites and servers that supply or distribute various other software. Accordingly, the above detailed description should not be interpreted restrictively in all respects but should be considered exemplary.
