In this case,

The guide information constructing unit 115 extracts only the product information from the product information data stream and stores the product information in the supplementary information memory 116 or retrieves the retrieved goods so that the user can select and designate the product information through the screen of the web TV 400 As shown in FIG.

When the product information is transmitted together with the moving picture signal by the Internet broadcasting, which is different from the digital broadcasting of the airwaves, the product information and the connection information linking with the screen to be outputted video are not included in the product information or the video information, May be provided. Accordingly, in the embodiment in which the Internet broadcast signal is provided together with the product information without the connection information, the web TV 400 may be configured such that, at the time when the product information is received, Or the still image is estimated as an image screen linked with the product information, and connection information with the image is generated and stored together with the product information in the additional information memory 116 . In the case where the connection information is stored in the additional information memory 116 as described above, a guide screen for selecting a product is necessary for an embodiment providing the guide screen together with a video screen related to a product that has been viewed or viewed. As in the embodiment of Fig. 7, it is not necessary to present a product name to be selected as a guidance screen and to present a screen that is not related to a product to be selected at all as a background screen.

As in the case of over-the-air broadcasting, when providing commodity information in Internet broadcasting, if the commodity code for the commodity is provided together, information on the same commodity is prevented from being duplicated and stored in the side information memory 116 .

The web TV 400 of FIG. 13 can also provide received product information to viewers in various forms, such as in the digital television 100 described above. That is, when the product name, the product code, and the local information are provided as product information, the additional information is stored in the additional information memory 116 as shown in FIG. 6, and when the viewer requests the guide information forming unit 115, A guide screen of the same type as that of FIG. When the icon data and the real information are provided, they are stored as shown in FIG. 8, and a selection screen is generated and provided in the form as shown in FIG. 9. When coordinate information and global information are provided, At the request of the viewer, a product selection screen as shown in FIG. 11 is generated and displayed on the screen.

When the viewer selects an arbitrary item on the selection screen, the controller 117 controls the network connection / processing unit 110 to transmit the organic information to the Internet according to the protocol, 119). Accordingly, when the requested web document is transmitted from the site of the corresponding URL, the network connection / processing unit 110 delivers the requested web document to the web browser driven by the control unit 117, And converts the video signal into a video signal of a video or a moving picture through the video decoder 112 and the audio decoder 114 and outputs it to the screen so that a viewer who requests information about the commodity So that additional information such as purchase information about the product can be confirmed.

Although all of the embodiments described above are provided to provide viewer information on the Internet on the Internet in order to provide product information when the viewer requests and receive specific information about the product, May be provided through a separate procedure at the request of the user.

The following embodiment provides the RO access information through a separate process and will be described based on the operation of the digital television 100 of FIG.

The digital television 100 stores the product information received together with the broadcast signal in the service information memory 19 so that the user can shop after the end of the viewing without interruption of the viewer's current program viewing. At this time, in order to prevent the product information from being duplicated and stored, the received product code is confirmed. That is, as described above, the section filter unit 18 compares the currently received commodity code with the commodity code of the commodity information in the previously received and stored service information memory 19, and if it is already received, If there is no code, product information having a newly received product code is stored in the service information memory 19.

In addition to the product code, various pieces of information may be selected and used as product identification information used for comparison storage of product information. That is, the product name may be used as product identification information for confirming duplicate storage. However, in the case of using the product name as it is, it may not be classified even though it is another product. Therefore, the name of the place where the product was located or the name of the casting where the product was worn may be stipulated as the product name.

For example, the product recognition information may be used in the form of 'pants (Kim),' 'pants (pa), or' computer (pa).

In the state where the product information is stored in the service information memory 19 without the shopping information of the URL, the viewer can view the broadcast program, or after the broadcast program ends, the control unit 21 stops the decoding of the broadcast program and controls the guide information constituting unit 20 so that the service information memory 19 stores the service information, So that the product information stored up to that point is displayed on the screen of the digital television 100. [

When the viewer selects one product in the state in which the product information is output, the product information including the recognized information product code, the product name, or the product name having the staged information is transmitted to the site, For example, the program is transmitted to a broadcasting station site that is transmitting the broadcasting program. Accordingly, the server of the broadcasting station site searches the connection address of the site which can confirm the product recognition information, obtain the additional information about the product, and transmits the connection information to the network connection part 24 of the digital television 100 ).

The control unit 21 having received the connection information transmits the connection information to the Internet via the network connection unit 24 and receives necessary information from a site capable of obtaining additional information such as purchase information on the selected product And the received information is outputted as an image showing the information required by the web browser function of the network connection unit 24 and the guide information construction unit 20.
