The present invention relates to digital broadcasting, and more particularly, to a technology related to a product provided through digital broadcasting.

Digital broadcasting is a method of compressing and broadcasting television signals in the form of digital signals rather than analog signals. The digital broadcasting method encodes video and audio signals into digital information, and also encodes system information and program information according to the PSIP (Program and System Information Protocol) standard and transmits them as a transport stream (TS). Then, the digital broadcasting receiver decodes the video and audio streams from the TS and displays them on the screen, and extracts information related to the broadcast program from data other than the video / audio information, and provides the program related information to the viewer through the electronic program guide (EPG). It is displayed on the screen and informed.

Meanwhile, data broadcasting provided according to a digital broadcasting method means that additional data can be added to video and audio signals. There are two types of data broadcast services, depending on whether uplink is used. Here, a return channel or a back channel is a channel connected from a receiver to a broadcasting station and is an essential element for providing a complete interactive TV service.

First of all, a data service that does not use an uplink channel has no interaction through a network, but a service that interacts with a receiver by memory in a digital broadcast receiver. That is, a service for receiving and viewing only data transmitted from a data server of a broadcasting station, and is used to provide EPG, digital text service, simple information related to a program, weather forecast, and stock information. For example, when a product placement (PPL) product is displayed during a drama broadcast, a viewer may request additional information (eg, price, size, etc.) of a desired product through a remote control operation, and at this time, the digital broadcasting receiver may store a memory. Read additional information about the product stored in the and display on the screen. Accordingly, the viewer can check basic additional information about the PPL product.

The uplink data service is a service in which viewers can find detailed information related to broadcast contents or directly participate in a program such as a quiz by interacting through a network. When the uplink channel is supported, more detailed information can be connected to the advertiser's server when the commercial is broadcasted, and the purchase can be made. For example, when a product placement (PPL) product comes out during a drama broadcast, the viewer may request more additional information in addition to the additional information basically provided for the product by operating a remote controller. The request signal is then transmitted to the broadcasting station through an uplink channel, and the broadcasting station returns additional information about the corresponding product. As a result, the merchandise retailer is able to perform advanced product marketing and sales through digital broadcasting.

However, even though two-way communication according to the conventional digital broadcasting is supported, the viewer must bear the inconvenience of checking the additional information and purchasing of PPL products. For example, if a PPL product is provided during a drama broadcast, the broadcasting company sends not only the video / audio information of the drama but also additional information about the product, but at this time, since a large amount of data cannot be sent, the additional information of the product Only essential information is sent. When the viewer requests additional information about a product, the digital broadcasting receiver first reads the additional information (for example, the price and size of the product) stored in the built-in memory and displays it on the screen. However, when the viewer wants more additional information about the product, the viewer communicates with the broadcaster to provide additional information. To this end, the viewer has to operate a lot of buttons on the remote control as instructed through the graphical user interface (GUI). You must accept. That is, the interface for receiving additional information about the product is difficult. In addition, when purchasing a product, a separate action such as ARS must be performed, and it also causes a concern that personal information is leaked by an insecure purchase method. In addition, the broadcaster must be building a lot of information about the product.

SUMMARY OF THE INVENTION The present invention is derived from such a situation, and an object of the present invention is to provide a technical method for supporting a broadcast viewer to easily and securely obtain additional information and purchase a product through a broadcast.

According to an aspect of the present invention, a digital broadcast receiver according to an aspect of the present invention receives a broadcast signal, extracts a product code therefrom, and transmits the RF signal.

According to this aspect of the present invention, the viewer can easily obtain additional information by transmitting the product code to the corresponding server by one button operation using a mobile phone that receives the product code transmitted from the digital broadcasting receiver. It is possible to connect to the purchase quickly, and also to make payments securely by using the mobile phone with enhanced authentication.

The foregoing and further aspects of the present invention will become more apparent through the preferred embodiments described with reference to the accompanying drawings. Hereinafter, the present invention will be described in detail to enable those skilled in the art to easily understand and reproduce the present invention. For reference, in the embodiment of the present invention, it will be assumed that the digital broadcasting method is ATSC.

1 is a schematic network diagram according to an embodiment for implementing the present invention. The product information providing system 10 obtains information about a product, generates a product code, and makes additional information about the product into a DB. Next, the product information providing system 10 transmits a product code to a broadcast transmission system 20 operated by a broadcast brokerage company such as an SO and a DMB provider. According to an example, when the product information providing system 10 is operated by the program provider PP, the product code is transmitted to the broadcast transmission system 20 through the linked data broadcasting together with the corresponding broadcast program including the product. Is provided. According to another example, when the product information providing system 10 is operated by the EPG operator, the EPG operator generates the product code after receiving the product information from the PP and / or the product seller and broadcast broadcasting system 20. To provide. According to another example, the product information providing system 10 may be operated by a broadcast brokerage company.

The broadcast transmission system 20 transmits a broadcast signal as known. In this case, since the broadcast signal includes not only a broadcast program but additional data, a product code may be included in the broadcast signal and transmitted. Since the data broadcast itself is a known technology, a detailed description thereof will be omitted.

The digital broadcast reception device 30 extracts a product code from a broadcast signal and selects a product displayed on a broadcast screen through a remote controller while the viewer watches the broadcast. The digital broadcast reception device 30 RF-delivers a product code for the selected product. The mobile communication terminal receives the product code RF transmitted from the digital broadcast receiving device 30, and transmits the product code to the product information providing system 10 when the terminal user wants the product additional information. The product information providing system 10 transmits product additional information corresponding to the received product code to the mobile communication terminal. When the terminal user wants to purchase a product, a product code is transmitted to the payment system 40, and a product purchase process according to a normal procedure is performed.

As shown, the digital broadcast receiver 30 includes a broadcast receiver 100 for receiving a broadcast signal, a broadcast player 200 for processing and outputting a broadcast signal received by the broadcast receiver 100, and a broadcast; Commodity code extraction unit 300 for extracting the product code included in the signal, the transmitter 400 for RF transmission of the product code extracted by the product code extraction unit 300, and controls the overall device, And a control unit 500 for controlling the output of the product code extracted by the code extracting unit 300 to the transmitting unit.

3 is a block diagram illustrating the configuration of FIG. 2 in more detail. First, the broadcast receiver 100 includes a tuner and a demodulator. The broadcast receiving unit 100 adjusts a sync of a channel under the control of the control unit 500, and then obtains a transport stream (TS) of an actual bit string through demodulation of a demodulator according to a modulation scheme. Serve The modulation method may be determined according to the digital broadcasting method. In the case of the ATSC method, an 8-VSB modulation method is adopted. Accordingly, it is possible to obtain the transport spring TS from the tuned broadcast signal through the application of an 8-VSB demodulator.

The demultiplexer (DEMUX) 210 performs demultiplexing to separate the video bitstream, the audio bitstream, and the service information data section from the transport stream TS. The demultiplexer 210 demultiplexes the video bitstream (MPEG-2 bitstream) and the audio bitstream (AC-3 bitstream) into the MPEG-2 decoder 220 and the AC-3 decoder 230, respectively. This is because the video is MPEG-2 (ISO / IEC 13818-1) and the audio uses AC3 (Dolby Digital sound) in TS generation required for digital broadcasting. The digital video signal decoded by the MPEG-2 decoder 220 is converted into a video display through the display processor 240 and then output as a video signal. For this purpose, the display processor 240 preferably includes an NTSC encoder. The AC-3 decoder 230 decodes the audio bitstream and outputs the audio signal as an audio signal. Each video and audio signal output is provided to a TV receiver which is a display device.

The product code extracting unit 300 is a component for extracting a product code included in the service information data section demultiplexed and output from the demultiplexer 210, and divided into PSI, PSIP, and product code according to the type of service information data. Extract the product code. For example, since the header of the packet constituting the service information data demultiplexed and separated from the demultiplexer 210 has type information for identifying the type of service information, the product code extracting unit 300 checks the header information. Product code can be extracted through.

The product code extracted by the product code extractor 300 may be input directly to the transmitter 400 under the control of the controller 500 or may be input to the transmitter 400 according to an event after storage. The transmitting unit 400 is configured to transmit the product code in accordance with the RF method, preferably RF transmission of the product code in consideration of the specification of the RFID method.

According to an example, when a broadcast signal is transmitted from the broadcast transmission system, the corresponding product code may be synchronized with the broadcast video data including the product in the broadcast stream. In this case, according to an exemplary embodiment, the controller 500 controls the product code extracted by the product code extractor 300 to be inputted to the transmitter 400 according to the output of the corresponding broadcast video screen to transmit the RF. In this case, a message indicating that the product code is transmitting RF may be displayed on the broadcast screen, and such information may be included in the broadcast signal. In addition, the product code may be two or more.

According to another embodiment, the control unit 500 outputs the product code extracted by the product code extraction unit 300 to the transmitter 400 when an event occurs. The event may be an RF transmission command of a product code for the product when the broadcast reproducing unit 200 reproduces a broadcast stream related to the product according to an exemplary embodiment. According to an example, the broadcast reproducing unit 200 may obtain information on reproduction of a broadcast stream related to a product from product page information included in a broadcast signal. The product page information herein refers to a broadcast video screen including a product in a broadcast stream.

The RF transmission command may be a signal wirelessly transmitted from a remote controller or a mobile communication terminal. For this purpose, the digital broadcast reception device 30 may further include a wireless signal receiver 600. The wireless signal receiving unit 600 receives a remote control signal emitted from a remote control device or a mobile communication terminal having a remote control function as a remote control device, decodes it, and transmits it to the control unit 500.

The mobile communication terminal preferably includes a receiver configured to receive a product code RF transmitted from the transmitter 400 in consideration of the RFID scheme. The mobile terminal displays the product information on the received product code on the screen. According to an example, the product code may include a product ID, a product name, a URL for obtaining product additional information, and URL information for purchasing a product. In this case, the mobile communication terminal displays a brand name and, if two or more product codes are received, displays a brand name list. According to another example, the commodity code may be only a commodity ID. The URLs for the product information providing system 10 and the payment system 40 may be specified in advance, or may be a method of transmitting a product ID to a corresponding system according to a product ID selection according to a user's terminal key operation. .

When the user performs a key operation for requesting additional information (preferably a single key designated), the mobile communication terminal accesses the product information providing system 10 through the corresponding URL and transmits the selected product ID and terminal information to transmit the additional information. request. The product information providing system 10 then provides the mobile communication terminal with additional information about the product corresponding to the received product ID, for example, a price, a size, offline store information, etc. when the product is a clothes. When the user performs a key operation for purchasing a product, the mobile communication terminal accesses the payment system 40 through the corresponding URL and transmits the selected product ID and terminal information to request a payment necessary for purchasing the product.
