1 is a block diagram of an IPTV service system according to an embodiment of the present invention. Referring to the embodiment of FIG. 1, the IPTV service system of the present invention includes a display apparatus 110, a set top box 120, a content server 130, an advertisement server 140, and a network 150.

The display apparatus 110 refers to one of display apparatuses such as a liquid crystal display (LCD) television and a plasma display panel (PDP) television. The display apparatus 110 expresses the multimedia content received from the set top box 120 on a display device such as a liquid crystal so that the user can recognize it visually.

The network 150 is a communication network used to transmit and receive data between the set top box 120 and the content server 130 or the advertisement server 140. Network 150 refers to one of ADSL, FTTH or any communication network that will be developed and commercialized in the future.

The content server 130 stores digital multimedia content such as VOD, and receives a request for providing specific content from the set-top box 120 to transmit data of the corresponding content through the network 150.

The advertisement server 140 is a storage storing advertisement data including advertisement image and detailed information of the corresponding advertisement target, and information data of the advertisement. The information data of the advertisement includes the coordinate information displayed on the screen of the display apparatus 110 in which the advertisement image and the detailed information are connected, the connection information indicating what the detailed information corresponding to the advertisement image is, and the web page corresponding to the advertisement image or the detailed information. URL information and the like.

The set-top box 120 refers to a box placed on a TV set having a home communication terminal function required to use a next generation interactive multimedia communication service such as VOD, image board home shopping, and network game. The set-top box 120 downloads digital multimedia contents through message transmission and reception with the content server 130 and the advertisement server 140, converts an image signal of the corresponding contents, and delivers them to the display apparatus 110.

In the present invention, the set-top box 120 downloads the advertisement data and the information data of the corresponding advertisement from the advertisement server 140 while not downloading the multimedia content from the content server 130. That is, in the set-top box 120, if there is no user input for a predetermined time since the power is turned on or a predetermined time elapses after the last data transmission and reception, the set-top box 120 transmits a message requesting the advertisement data and the information data of the advertisement to the ad server 140. The data is downloaded and stored in the database, and the advertisement management table is updated by referring to the information included in the information data.

Even if the set-top box 120 displays content while downloading the content from the content server 130, since the advertisement data and the information data of the advertisement are already received and stored in the set-top box 120, the content data in the set-top box 120 It is possible to reduce the load of the network 150 and the set-top box 120 itself, which is generated while receiving and advertising data and the like at the same time.

When the subscriber of the IPTV service of the present invention recognizes the advertisement image displayed in step S250 and generates a specific event, the display apparatus 110 transmits the corresponding event occurrence information to the set-top box 120 (S255). The event may be generated by, for example, pressing an identification key of the remote controller or the display apparatus 110.

In the set-top box 120 receiving the event information and detecting the fact that the event occurred, the detailed information is displayed on a part of the screen of the display apparatus 110 by referring to the connection information of the detailed information corresponding to the advertisement image in the advertisement management table. (S260). In this case, the set-top box 120 is displayed on the display apparatus 110 with reference to the start coordinates and end coordinates of the detailed information among the coordinate information stored in the advertisement management table, and may be the same as the display process of the advertisement image. In this case, the displayed detail information may be web page information displayed on the display apparatus 110 by searching URL information of a web page corresponding to an advertisement image from the advertisement management table in the set-top box 120.

When the subscriber of the IPTV service of the present invention recognizes the detailed information displayed in step S260 and generates an event by pressing the confirmation key of the display apparatus 110 or the remote controller, the corresponding event occurrence information is transmitted to the set-top box 120. (S265). In step S265, the set-top box 120 that detects the occurrence of an event searches for connection information of details in the advertisement management table and displays other details on the display device 110, or corresponds to the details in the advertisement management table. Search for the URL information of the web page to be set up the session to the seller server 160, which stores the web page of the URL (S270).

When the session is established in step S270, the set-top box 120 downloads the corresponding webpage information from the seller server 160 (S275) and displays it on the display apparatus 110 (S280). When the subscriber of the IPTV service of the present invention views the corresponding web page displayed on the display apparatus 110 and inputs purchase information about a specific product or service, the purchase information is transmitted to the seller server 160 through the set-top box 120. do.
