Hereinafter, embodiments of the present invention will be described in detail with reference to FIGS. 2 to 7.

2 is a diagram showing the configuration of an electronic commerce system using digital satellite broadcasting according to an embodiment of the present invention.

In the drawing, reference numeral 110 is a broadcasting program database, 120 is a forwarding database, 130 is a program controller, 140 is an application server, and 150 is a data ENC. 160, Receipt Data Collecting Server, 170 is Multiplexer, 240 is Receiver or Set-Top Box, 280 is Return Data Collecting Server, 290 is An Electronic Commerce Server, 300 represents a Payment / Payment Server, and 400 represents a Subscriber Authorizing Server. Reference numeral 100 denotes a broadcasting center. In the drawing, the return data collection server 280, the e-commerce server 290, the payment / payment server 300 or the subscriber authentication server 400 may be configured to operate outside the broadcasting center.

In the drawing, the broadcast program database 110 stores broadcast data of a program such as a movie, a sports, a music, a news, a home shopping, and the like. The broadcast data of a program stored in the broadcast program database 110 is converted and stored in, for example, MPEG-2 format or stored in a file of any format.

Meanwhile, the forwarding database 120 forwards data such as product catalogue, purchase conditions, and application programs to be transmitted to the receiver through a data service, for example, in response to a home shopping program. Data). Similarly, for example, forwarding data corresponding to a movie program may include information about a director, an award, and an actor related to the movie.

The broadcast control unit 130 extracts broadcast data from the broadcast program database 110 and transmits the broadcast data to the conversion server 140 according to a broadcast schedule associated with an arbitrary TV channel broadcast program, and corresponds to the extracted broadcast program. Forwarding data is extracted from the forwarding database 120 and controlled to be transmitted to the delivery server 150.

The conversion server 140 directly transmits the broadcast data received from the broadcast control unit 130 to, for example, the MPEG-2 format, to the delivery server 150, and converts the broadcast data to the MPEG-2 format if it is another format. To 150.

Then, the transmission server 150 inserts a PID into the broadcast data of television or music extracted and transmitted from the broadcast program database 110 and the forwarding data transmitted from the forwarding database 120, and transmits one MPEG according to a given bandwidth. It is written as -2 and transmitted to the multiplexer 170. The transmission server 150 is configured for each channel of a broadcasting station.

The multiplexer 170 multiplexes and outputs broadcast data transmitted from a plurality of broadcast servers 150 according to each broadcast channel. The multiplexed broadcast data is up-linked to the satellite 210 through the satellite transmission antenna 180.

On the other hand, in the case of cable broadcasting, broadcast data from the multiplexer 170 is transmitted to the receiver through the cable 190. Similarly, in the case of terrestrial broadcasting, broadcast data from the multiplexer 170 is transmitted over the air through an antenna on the ground.

Then, the receiver 240 receives the broadcast signal broadcast through the satellite 210 through the satellite receiving antenna 220 and converts it into a TV signal and outputs it to the TV 250.

At this time, the subscriber can perform electronic commerce while watching the satellite broadcast. That is, such an electronic commerce orders the purchase information to be purchased through the input device such as a remote controller or a wireless keyboard while inputting the purchase information to the receiver 240 while watching TV. After encrypting the purchase information input by the subscriber, the data is transmitted to the return data collection server 280 through a wireless communication network 260 such as PCS or a wired communication network such as a PSTN / dedicated line.

For example, if the subscriber moves frequently or needs to use only wireless communication for reasons such as moving, the receiver 240 may be configured to transmit the return data using the wireless communication network 260. On the other hand, if the subscriber does not want to use wireless communication and wants to transmit the return data using the telephone (PSTN), the subscriber may be configured to be connected to the return data collection server 280 through a modem after joining the telephone. . In addition, when the subscriber is using a dedicated line, the subscriber can be configured to be connected to the return data collection server 280 through a LAN card or an ADSL modem card.

Therefore, in the case where the wireless communication network is set to be used, the receiver 240 transmits the return data as a short message server (SMS) or e-mail using the subscription telephone number of the return data collection server 280 as a receiver. In addition, when the PSTN is configured to use the PSTN, the receiver 240 connects to the return data collection server 280 through a mounted dial-up modem and transmits the return data. And if it is set to use a dedicated line, the receiver 240 transmits the return data to the email account of the return data collection server 280.

Then, the return data collection server 280 collects the return data from the receiver 240 and transmits the return data to the electronic commerce server 290 to be processed.

The return data collection server 280 is configured to receive a phone number from any wireless communication network provider and receive an SMS through the subscribed phone number when it is desired to collect return data through SMS. On the other hand, when the return data is to be collected through the PSTN, the return data collection server 280 is provided with a plurality of modems to communicate with the receiver 240 after subscribing to the PSTN phone possible, for example RAS (Remote Access Service) to provide.

The e-commerce server 290 deciphers the return data received from the return data collection server 280, and then determines whether the return data is valid. At this time, if the received return data is valid, the subscriber ID is checked from the subscriber authentication server 400 using the subscriber ID included in the return data.

Subsequently, the electronic commerce server 290 processes the transaction based on the product information (eg, product code, order quantity) included in the received return data. When the transaction processing is normally performed as described above, the electronic commerce server 290 processes payment through the payment / payment server 300 based on the payment request information included in the return data.

Finally, the electronic commerce server 290 transmits the processing result (transaction confirmation data) to the transaction confirmation data collection server 160 when all the transaction processing is made based on the received return data. Then, the transaction confirmation data collection server 160 transmits the collected transaction confirmation data (Receipt Data) to the transmission server 150, the transmission server 150 transmits the transaction confirmation data to the subscriber through the data service (Data Service) Let's do it.

4 is a flowchart schematically illustrating an electronic commerce method using digital satellite broadcasting according to an embodiment of the present invention.

First, the forwarding data is transmitted by the broadcast control unit 130 and the transmission server 150 of the digital broadcasting center (S110).

The forwarding data transmitted as described above is received by the receiver 240 (S120). As such, when the forwarding data is received by the receiver 240, the receiver executes an application program so that the subscriber can order the goods.

Then, the subscriber inputs the order information through the application program to be executed when you want to order the product (S130). The application is written, for example, as a standard of the Digital Video Broadcasting-Multimedia Home Platform (DVB-MHP) and is executed by a processor embedded in the receiver. The application program may be operated to be applied to all digital broadcasts in common or may be operated differently for each broadcast program. Therefore, if the application program is to be applied in common, the application program from the broadcasting center can be forwarded to the receiver only once, installed and executed, and can be configured to be used as data of the application program by transmitting only product purchase information according to each broadcast program. . On the other hand, when the application program is to be operated differently for each broadcast program, the application program and product purchase information are forwarded whenever necessary so that they are executed in the receiver.

When the subscriber enters all the product information to be purchased and presses the Send button, for example, the application program returns the input order information (return data) to the receiver (S140).

Then, for example, the return data collection server 280 of the receiving side receives the return data and transmits it to the e-commerce server 290 (S160). When the return data is transmitted to the e-commerce server 290 as described above, the e-commerce server 290 performs a transaction processing based on the information of the return data (S170).

When the transaction processing is completed, the electronic commerce server 290 generates a transaction result in a transaction confirmation data format and transmits it to the transaction confirmation data collection server 160. Subsequently, the transaction confirmation data (Receipt Data) transmitted to the transaction confirmation data collection server 160 is transmitted by the transmission server 150 (S180).

Transaction confirmation data sent by the transmission server 150 is received by the receiver 240 of the subscriber is displayed on the TV 250 (S190). In this way, one purchase request from the subscriber and an electronic commerce of transaction and transaction confirmation are all made.

FIG. 5 is a flowchart showing in detail an example of broadcasting data transmission in an electronic commerce system using digital satellite broadcasting shown in FIG. 2.

First, broadcast data of a program to be broadcast in the current broadcast channel is extracted from the broadcast program database 110 (S410). Subsequently, the extracted broadcast data is converted into a data format conforming to the broadcast standard through the conversion server 140 (S420). Subsequently, the converted broadcast data is transmitted through the transmission server 150 (S430).

Subsequently, the transmission server 150 checks whether there is forwarding data to be transmitted to the current broadcast channel through the broadcast control unit 130 (S440). In this case, if there is forwarding data to be transmitted, it is extracted from the forwarding database 120 (S450). Then, the transmission server 150 inserts the extracted forwarding data into the additional stream of the current broadcast channel and transmits it (S460).

Finally, the transmission server 150 checks the transaction confirmation data collection server 160 and checks whether there is transaction confirmation data to be transmitted through the current channel broadcast (S470). At this time, if there is transaction confirmation data to be transmitted, transaction confirmation data is extracted from the transaction confirmation data collection server 160 (S480). Then, the transmission server 150 inserts the transaction confirmation data thus extracted into the additional stream of the current broadcast channel and transmits it (S490).

FIG. 6 is a flowchart showing an example of data processing in a receiver of an electronic commerce system using digital satellite broadcasting shown in FIG. 2.

First, when the subscriber selects a random channel of satellite broadcasting, the receiver receives data of the current channel (S210). The data thus received is decoded.

Subsequently, a processor (for example, a microprocessor or a CPU) of the receiver determines the type of the decoded data (S220), and allows each to be processed according to the result. That is, the type of data is classified into data of TV broadcast or music broadcast, forwarding data related to product order, and transaction confirmation data indicating transaction confirmation.

In this case, in the case of TV broadcast data, the received data is converted into a TV signal (S310) and then output to the TV (S320). Similarly, when the data is music broadcast data, the received data is converted into an audio signal and then output through the audio device.

In the case of forwarding data, all of the forwarding data is downloaded and stored (S230). In this case, if the downloaded forwarding data is an application program, the receiver executes the operation (S240). In this way, the receiver is in a state capable of receiving a product order, it is determined whether the button input from the subscriber (S250).

In this way, if the subscriber wants to search the product information while watching the broadcast, for example, the user clicks the "Product Catalog" button. Then, the receiver extracts the product information from the downloaded forwarding data and displays it on the TV screen (S350). At this time, the display on the screen is performed by an OSD (On Screen Display) or an overlay (Overlay) method.

If the subscriber wishes to continue to order the goods, for example, he clicks the "Order" button. Then, the application program displays general information regarding the quantity of goods that can be purchased, the type of payment method, the delivery date, etc. based on the downloaded forwarding data (S260). Based on such information, the subscriber enters all the order information in the input field displayed on the screen (S270). When the input of the order information is completed, the subscriber clicks, for example, a "Send" button (S280).

Then, the application program encrypts the input order information is converted into a packet (S290). Finally, the receiver returns the converted packet to the receiver (S300). At this time, the receiver has a chip of a terminal for PCS or IMT-2000, for example, and transmits a packet to a telephone number or an e-mail address included in a return address of the received forwarding data. The packet may be transmitted using, for example, a short message service (SMS) or an email service.

FIG. 7 is a flowchart illustrating an example of electronic commerce processing in an electronic commerce server of the electronic commerce system using digital satellite broadcasting shown in FIG. 2.

First, the e-commerce server 290 receives a packet of return data transmitted from the receiver 240 (S510). Since the packet is encrypted by a predetermined encryption algorithm, it is determined whether the packet has valid information after decryption (S520). For example, when the timestamp of the return data transmitted from the receiver is out of the time registered in the valid information, it is determined that the return data is invalid and discards the packet.

At this time, if the packet is valid, the subscriber is authenticated through the subscriber authentication server 400 based on the information of the subscriber ID of the return data (S530). When the subscriber's authentication is completed as described above, the electronic commerce server 290 processes the transaction based on the product code, the order quantity, the payment method, and the delivery information of the return data (S540). At this time, the payment is made through the payment / payment server (300). Finally, the e-commerce server 290 registers the result of the transaction processing (S550).

As described above, when the transaction processing for the subscriber's order is finished, the electronic commerce server 290 generates transaction confirmation data so that the transaction result can be transmitted to the subscriber (S560). The generated transaction confirmation data 160 is transmitted from the electronic commerce server 290 to the transaction confirmation data collection server 160.

Although the above embodiment has been described using digital satellite broadcasting as an example, it is also applicable to wired cable broadcasting and airwave broadcasting.

The present invention provides a shopping program through the conventional satellite broadcasting and commerce receiving a purchase order from the subscriber is not only equipped with the equipment to answer the call in the call center, but also requires a large number of manpower increases costs When the order is congested, the call center cannot respond, and the orderer has to wait until the call is made and solves the problem that the payment is not secure because the user must provide information such as a credit card through the telephone. E-commerce can be performed through the data broadcasting service of digital broadcasting, and since the return data from the set-top box is transmitted through the wireless communication network, the data can be secured and the set-top box can be made mobile.
