Inconvenience such as receiving may occur. In order to solve this problem, the online purchase system according to an embodiment of the present invention checks each IP information before connecting the terminal device 100 and the content providing device 200, so that the user does not intend Possibility of unnecessary communication with the content providing device 200 can be prevented. Hereinafter, an online purchase method according to an embodiment of the present invention will be described with reference to FIG. 4 .

4 illustrates a flow chart of an online purchase method according to an embodiment of the present invention.

Referring to FIG. 4 , the terminal device 100 may receive a radio signal including product information on a target product from the content providing device 200 (S110). For example, the content providing device 200 may output and provide content such as a home shopping channel, movie, or drama to a user. At this time, the content providing device 200 may transmit a wireless signal while providing the content. Depending on embodiments, radio signals may be transmitted in the form of inaudible sound waves in addition to voice signals included in content.

In the case of transmitting a wireless signal as an inaudible sound wave, a frequency of 18,500 Hz to 24,000 Hz, which is a frequency band that can not be heard by normal users, can be used, but is not necessarily limited thereto, and the frequency of the wireless signal depends on the operating environment and application Band can be adjusted.

Depending on the embodiment, it is also possible to use a beacon signal or a Bluetooth Low Energy (BLE) signal as a wireless signal. In the case of BLE, as one of the Bluetooth technologies for transmitting and receiving low-power and low-capacity data in a 2.4GHz frequency band having a reach radius of about 10 meters, the content providing device 200 can be implemented to transmit a BLE signal. Furthermore, it is also possible to transmit the BLE signal in a subaudible range by implementing a high frequency or ultrasonic wave.

The product information included in the wireless signal may include identification information for identifying a target product, URL (Uniform Resource Locator) address of a web page for purchasing a target product, and the like. Here, the target product may include various goods and services, such as services and contents, as well as objects having a physical form.

Depending on the embodiment, product information on a plurality of products may be included in the radio 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 a plurality of products to proceed with a purchase procedure.

Thereafter, the terminal device 100 may check whether the content providing device 200 is accessing the same local area network as the terminal device 100 by using a radio signal (S120). That is, the terminal device 100 can check whether the corresponding content providing device 200 is a trustworthy device or the content providing device 200 that the user intends to receive a wireless signal, and only when the confirmation is made. A radio signal may be received from the corresponding content providing device 200 .

For example, as shown in FIG. 5, there may be cases in which one terminal device 100 simultaneously receives radio signals from a plurality of content providing devices 200a and 200b. In this case, one may be the IPTV 200a installed in the living room of one's house, and the other may be the IPTV 200b of the next house. In other words, since the wireless signal transmitted by the next-door neighbor's IPTV 200b corresponds to a wireless signal that the user does not want, it is necessary to restrict reception to only the wireless signal transmitted by the user's own IPTV 200a.

To this end, the terminal device 100 may check whether the corresponding content providing device 200 is accessing the same local area network as the terminal device 100, and only when connected to the same local area network, the corresponding content providing device 200 ) can be determined to correspond to the reliable content providing device 200. That is, since the terminal device 100 is connected to its own access point 300a, such as its own home or office, its own content providing device 200 only when the content providing device 200 is also connected to the same access point 300a. ) can be determined. In general, since both the terminal device 100 and the content providing device 200 are connected to their own access point 300b, when they are connected to the same access point 300a, it is determined as a reliable content providing device 200. can do.

Depending on the embodiment, it is also possible to determine whether the content providing device 200 is a trustworthy device based on the connection history of each of the access points to which the terminal device 100 has connected. That is, even if the terminal device 100 is not currently accessing an access point, the terminal device 100 may have a connection history of previous connections to an access point such as one's home or office. Therefore, it is possible to compare the access points to which the content providing device 200 is currently connected by using the access history, and as a result of the comparison, when the content providing device 200 is connected to the access point included in the connection history of the terminal device 100, It can be determined by a reliable device. That is, even when the terminal device 100 is not currently connected to the access point, it can be determined that the corresponding content providing device 200 is connected to the same local area network using the access history.

On the other hand, if the access points 300a and 300b to which the terminal device 100 and the content providing device 200b connect are different, the content providing device 200b corresponds to the IPTV next door, and thus the content providing device 200b corresponds to the IPTV of the next door. A radio signal provided by the providing device 200b can be disregarded.

Specifically, when transmitting a radio signal, the content providing device 200 may include and transmit information about each of the access points 300a and 300b to which the corresponding content providing devices 200a and 200b are connected, and the terminal device 100 ) can identify the access points 300a and 300b to which the corresponding content providing devices 200a and 200b are connected. For example, the content providing device 200 may include its own IP address information or SSID information in a wireless signal and transmit it.

In this case, the terminal device 100 may extract the IP address of the content providing device 200 included in the radio signal, and using the extracted IP address, the corresponding IP address corresponds to the local area network to which the terminal device 100 is connected. It may be determined whether the access point 300 corresponds to an IP address provided. If the IP address of the content providing device 200 corresponds to the IP address of the access point to which the terminal device 100 is connected, it can be determined that the terminal device 100 is accessing the same local area network.

In addition, depending on the embodiment, the terminal device 100 may extract the SSID of the access point 300 to which the content providing device 200 is connected from a radio signal, and the extracted SSID is the access point to which the terminal device 100 is connected. It can be determined whether it matches the SSID of the point 300. If the SSIDs match, it can be determined that they are accessing the same local area network.

Thereafter, when it is determined that the terminal device 100 is accessing the same local area network, the terminal device 100 may extract product information from the wireless signal and display the product information in the terminal device 100 (S130). That is, product information on a target product can be calculated by demodulating a signal corresponding to an inaudible frequency region among signals received using a microphone provided in the terminal device 100 according to a predetermined standard. have. Here, the product information may include a URL address of the target product, and the terminal device 100 may display a detailed product information page or a purchase homepage in the terminal device 100 using this.

Accordingly, the user can easily obtain product information of target products included in the currently displayed content using the terminal device 100, and can more conveniently proceed with a purchase procedure for this product.

Depending on the embodiment, it is also possible to allow the terminal device 100 to display product information only when a user's specific input is applied. That is, the user may not prefer to receive product information every time according to a radio signal transmitted by the content providing device 100, and may want to receive product information only when a desired target product appears. Accordingly, the terminal device 100 may display product information within the terminal device 100 only when a specific user input is applied.

Specifically, when it is determined that the content providing device 200 is accessing the same local area network as the terminal device 100, the terminal device 100 determines whether a predetermined setting operation of the user is input to the terminal device 100 thereafter. can do. That is, the user's movement can be detected using a sensor (not shown) provided in the terminal device 100, and the terminal device 100 can determine whether or not the detected user's movement corresponds to the setting operation. . For example, when a smartphone or the like is used as the terminal device 100, the terminal device 100 may be provided with various sensors such as a gyro sensor capable of detecting a user's movement, and accordingly, the terminal device 100 may detect a user's motion using a sensor and determine whether the user's motion corresponds to a predetermined set motion.

Here, when the setting operation is defined as an operation of 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 gyro sensor and the like, and the collected data is predefined. When the comparison data matches or is similar to the compared data by a certain level or more, it may be determined that the user's motion corresponds to a predetermined setting motion.

Then, when it is determined that the setting operation is input, the terminal device 100 can extract product information from the wireless signal and display the product information in the terminal device 100 . For example, when a user wants to purchase a product while watching a home shopping channel, the user simply performs a predetermined setting operation such as shaking the terminal device 100 such as his or her smartphone, and the target product of the home shopping channel. You can receive product information about the product, or directly connect to the purchase page of the target product, so that you can proceed with the purchase process for the product more conveniently.

Subsequently, the terminal device 100 may proceed with a purchase procedure for the target product according to the user's input (S140). For example, the terminal device 100 may use a wireless signal received from the content providing device 200 to provide product information on a target product and calculate a URL address at which purchase is possible, and corresponding to the URL address By automatically linking the web page, it is possible to provide product information and purchase procedures to the user for the target product.

Also, depending on the embodiment, it is possible to execute a specific application in the terminal device 100 to proceed with a purchase procedure for a target product. In this case, identification information indicating a specific application may be included in the radio signal, and when the identification information is included, the terminal device 100 may execute the corresponding application. Here, the corresponding application may be to provide a detailed description page for a target product extracted from a radio signal, a purchase procedure, and the like.

6 is a flowchart illustrating the operation of an online purchase system according to an embodiment of the present invention. Referring to FIG. 6 , first, the content providing device 200 may transmit a radio signal to the terminal device 100 . The radio signal may include product information about a target product appearing in the content output by the content providing device 200 and information about a local area network to which the content providing device 200 is connected. Here, although the case of transmission including the IP address of the content providing device 200 as information on the local area network is exemplified, it is also possible to transmit the SSID of the local area network according to the embodiment.

Then, the terminal device 100 can check whether the terminal device 100 is accessing the local area network, and if it is accessing the local area network, it can check whether the content providing device 200 is accessing the same local area network.

Here, if the terminal device 100 is not accessing the local area network, additional confirmation may be omitted, and product information included in the radio signal may be extracted and displayed in the terminal device 100 . That is, when 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 providing device 200 are connected to the same local area network, and thus the received radio signal without additional confirmation. Based on this, product information can be extracted and displayed. However, depending on the embodiment, even if the terminal device 100 is not accessing a local area network, the content providing device 200 is connected to the same local area network based on the access history of the terminal device 100 to the access points. It is also possible to determine whether or not a communication network is connected.

Meanwhile, when the terminal device 100 is accessing a local area network, an IP address of the content providing device 200 may be extracted from a radio signal, and it may be determined whether the corresponding IP address corresponds to an IP address within the local area network. . Here, if the corresponding IP address is not the IP address of the local area network to which the terminal device 100 is connected, processing of the corresponding radio signal may be stopped. That is, since communication with the content providing device 200 is not intended by the user, the wireless signal received from the content providing device 200 may be ignored.

On the other hand, when the IP address of the content providing device 200 corresponds to the IP address of the local area network to which the terminal device 100 is connected, it can be determined that the communication with the content providing device 200 is intended by the user. can Accordingly, product information can be extracted from the corresponding radio signal and displayed in the terminal device 100 . Thereafter, the terminal device 100 may proceed with a purchase procedure for the target product according to the user's input.

7 is a block diagram of a content providing system according to an embodiment of the present invention.

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

The terminal device 100 may receive an advertisement message pushed from a server (not shown) or the like, and the user may select a corresponding advertisement message by touching or the like. Here, product information on a target product may be included in the advertisement message, and the terminal device 100 may output a radio signal including the product information. The radio signal output by the terminal device 100 may be an inaudible sound file, and may be output through a built-in speaker (not shown) of the terminal device 100 or the like. Depending on the embodiment, it is also possible to output the radio signal as a beacon signal or a BLE signal.

Thereafter, the content providing device 200 may receive a radio signal using a built-in microphone, etc., and may extract a target product from product information included in the radio signal. In addition, the content providing device 200 may search for and output content corresponding to the extracted target product. For example, when the content providing device 200 is an IPTV, it is possible to change to a home shopping channel for a target product.

However, since the terminal device 100 distributes wireless signals to any content providing device 200 located nearby, inconvenience such as transmission of unnecessary radio signals to the content providing device 200 that the user does not want may occur. can In order to solve this problem, the content providing system 20 according to an embodiment of the present invention checks each IP information before connecting the terminal device 100 and the content providing device 200, so that the user can Possibility of unnecessary communication with the content providing device 200 unintentionally can be prevented. Hereinafter, a content providing method according to an embodiment of the present invention will be described with reference to FIGS. 8 and 9 .

8 is a flowchart of a method for providing content according to an embodiment of the present invention, and FIG. 9 is a flowchart illustrating the operation of a system for providing content according to an embodiment of the present invention.

Referring to FIGS. 8 and 9 , the content providing device 200 may receive a radio signal including product information on a target product from the terminal device 100 (S210). The terminal device 100 may receive an advertisement message or the like from a separate server (not shown), and the user may select the corresponding advertisement message by touching or the like. For example, an advertisement message containing phrases such as “OO T-shirt is currently on sale on AA home shopping channel, touch it to check AA home shopping channel on IPTV” can be sent, and the user can touch the advertisement message to view the contents The providing device 200 may request to output an AA home shopping channel. In this case, the terminal device 100 may generate and transmit a corresponding radio signal, and the content providing device 200 may receive the corresponding radio signal. Here, the radio signal may be transmitted in the form of an inaudible sound wave.

Thereafter, the content providing device 200 may check whether the terminal device 100 is accessing the same local area network as the content providing device 200 by using a radio signal (S220). That is, the content providing device 200 can check whether the corresponding terminal device 100 is a trustworthy device, and can receive a radio signal from the corresponding terminal device 100 only when it is confirmed.

For example, there may be cases in which a plurality of terminal devices 100 simultaneously transmit radio signals to the same content providing device 200 . At this time, one may be the user's terminal device 100, and the other may be the terminal device of the next door. That is, since the wireless signal transmitted from the terminal device next door corresponds to the wireless signal that the user does not want, it is necessary to restrict reception of only the wireless signal transmitted from the terminal device 100 of the user except for this.

To this end, the content providing device 200 may check whether the corresponding terminal device 100 is currently accessing the same local area network, and only when accessing the same local area network, the terminal device 100 can be trusted.

On the other hand, if the access point 300 to which the terminal device 100 and the content providing device 200 are connected is different, the terminal device 100 corresponds to the terminal device next door, so the corresponding terminal device 100 ) can be ignored.

Specifically, when the terminal device 100 transmits a radio signal, it may include and transmit information about the access point 300 to which the terminal device 100 is connected, and the content providing device 200 checks this and transmits the corresponding terminal device 100. It is possible to determine the access point 300 to which the device 100 is connected. For example, the terminal device 100's own IP address information or SSID information may be included in the wireless signal and transmitted. Depending on the embodiment, the terminal device 100 may transmit a connection history including IP address information or SSID information of previously accessed access points.

In this case, the content providing device 200 may extract the IP address of the terminal device 100 included in the radio signal, and by using the extracted IP address, the corresponding IP address is a local area network to which the content providing device 200 is connected. It can be determined whether it corresponds to the IP address provided by the access point 300 of . If the IP address of the terminal device 100 corresponds to the IP address of the access point 300 to which the content providing device 200 is connected, it can be determined that they are accessing the same local area network.

Depending on the embodiment, the content providing device 200 may extract the SSID of the access point 300 to which the terminal device 100 is connected from a radio signal, and the extracted SSID is the access point to which the content providing device 200 is connected. It can be determined whether it matches the SSID of (300). If the SSIDs match here, it can be determined that they are accessing the same local area network.

Thereafter, when accessing the same local area network, the content providing device 200 may output content related to product information included in the wireless signal (S230). That is, the content providing device 200 may extract product information from a wireless signal and search for content in which a target product corresponding to the product information appears. That is, among various contents that can be provided by the contents providing device 200, contents corresponding to product information may be searched for and found. Then, when the search is completed, the content providing device 200 may output the searched content and provide it to the user. That is, the content for the target product indicated in the advertisement message received by the user through the terminal device 100 may be output and provided to the user.
